Chimney Sweep Service

The shortcut: Sell the annual inspection, not the one-time sweep. A $200 yearly contract beats a $350 one-off you'll never see again — and it's how you survive the slow summer.

Industry: Cleaning & Maintenance Investment level: Low — $3,000-$10,000 Time to launch: 6-10 weeks Best for: People who don't mind ladders, soot, and crawling onto roofs in November. You're a fit if you can drive to clients, lift 40 lbs, and have basic handyman instincts (you've fixed your own gutters or swapped a water heater). What you'll likely make: ~$4-$6K/month after expenses in peak season (Sept-Feb), and ~$1.5-$2.5K/month in the slow stretch (May-Aug), blending out to roughly $40-$55K in year 1. Full math is in Section 3.

Market Opportunity

Most chimney sweeps are one or two people working out of a pickup truck. There's no Molly Maid of chimneys. The field is wide open in almost every metro, and homeowners book whoever shows up first when smoke backs into the living room.

US Janitorial Services (NAICS 561720, where chimney sweeping sits): $112.0B in 2026, growing 1.8% — IBISWorld Janitorial Services Market Size
62,099 cleaning firms across 66,471 establishments (2020 Census), most with fewer than 10 employees. The Chimney Safety Institute of America (CSIA) lists roughly 1,500 certified sweeps nationwide (CSIA Find a Sweep). Thin coverage in most metros.
NFPA 211 says chimneys, fireplaces, and vents should be inspected at least once a year. Homeowners don't know it; every insurer and home inspector does.
Heating-equipment fires cause an average of 48,530 home fires per year, a third tied to failure to clean — NFPA Home Heating Fires Report.

Target customer: Homeowners with wood-burning fireplaces or wood stoves, single-family homes built before 2000, income $90K+. Two strong adjacent customers: real estate agents who need a Level 2 inspection before close, and property inspectors who refer out the chimney portion of their report.

Why this is a good time to start: Wood stove sales jumped during the 2022-2023 energy spike. Those installs are hitting their second or third heating season — exactly when creosote buildup triggers call-backs. More insurers are also requiring a recent inspection report before renewing policies on homes with active fireplaces. The customer doesn't need convincing. They need someone with a ladder and a CSIA card.

Launch With AI

Pro section. Chimney sweeping is an annual-contract-and-realtor-partnership business — AI doesn't climb a roof in November and doesn't run a video camera scope through a flue. But the time you waste hand-typing the realtor cold-walk for Level 2 inspection bids, drafting the annual contract auto-renewal text, and writing the off-season dryer-vent + waterproofing cross-sell is exactly the time you should spend on one more real-estate-office drop-in or one more before/after photo. AI does the writing tail. You do the work that pays — Tuesday morning at 8am on a roof in October with 6 sweeps booked.

The trap most first-year sweeps fall into: they paste their service description into ChatGPT and ship the auto-generated "spring cleaning" copy. AI confidently writes "we deep-clean your chimney for cleaner air" — but the actual buyer is the realtor calling at 4pm Friday because escrow closes Tuesday and they need a Level 2 inspection report tomorrow. AI is for the writing tail (annual contract auto-renewal, realtor + home-inspector partnership, Level 2 inspection report, CSIA cred display, off-season cross-sell) — but every roof-safety call, every flue-condition judgment, every "I refuse this Level 2 because the homeowner won't let me video-scope" call is yours.

Important up-front: AI cannot scope a flue, identify creosote glaze that needs chemical treatment vs. mechanical removal, or have the conversation with the homeowner about why their pre-1990 unlined chimney is a Level 3 inspection risk. It will also confidently miss the 70/30 seasonality + the dryer-vent off-season cross-sell that bridges May-August — and that's the entire year-1 cash flow play. You own every roof decision, every NFPA 211 inspection level call, every photo-doc of every flue; AI scales the writing and the prospecting around them.

The Workflow

Annual contract auto-renewal package (ChatGPT + Jobber + Canva, ~30 min one-time setup). The annual contract is the entire business. Paste:

"I'm a CSIA-certified chimney sweep. I want 50%+ of my Level 1 sweep customers on annual contracts by end of year 1. Build me the auto-renewal package: (a) the at-checkout in-home pitch I deliver at every Level 1 sweep ('You're set for this year — want me to put you on my annual contract? $200/year for inspection + sweep, billed every August so I'm on your calendar before the cold weather hits. I save your card now, you don't think about it again. Want me back next August?' — close rate 50%+ when asked in-home), (b) the 1-page annual contract sell-sheet (Canva: my CSIA badge + cert #, the 4-year value math ($200 × 4 = $800 vs. $325 × 4 = $1,300 = $500 saved), the 'I call you a week ahead' commitment, the cancel-anytime clause, my insurance proof, my Calendly), (c) the auto-renewal Jobber automation that fires August 1st every year ('hi [first name], it's August — your annual contract chimney sweep is coming up. I'll be at [address] [date] at [time] — reply C to confirm, R to reschedule, X to cancel. Card on file billed $200 the morning of the visit'), (d) the post-sweep annual recap email I send every December ('hi [first name], here's your [year] chimney service summary: [date] sweep + Level 1 inspection, creosote rated [Y] (light/moderate/heavy), photos attached, NFPA 211 compliance status. Renews August next year — your card stays on file unless you cancel'), (e) the absolute don'ts: NEVER discount the annual contract below $150 (you bleed margin), NEVER pitch on the phone (in-home close rate 50% vs. phone 15%), NEVER skip the December recap (it's why renewal sticks). Tone: warm friend + senior CSIA sweep. Output paste-ready Jobber automation + Canva sell-sheet."

50 annual contracts at $200 = $10K of locked August revenue before any new customer calls. That's the slow-summer rent paid in advance.
Realtor + home-inspector Level 2 partnership package (ChatGPT + Canva, ~45 min one-time setup). Level 2 inspections are the highest-margin work + pay year-round. Paste:

"I'm a CSIA-certified chimney sweep with a video inspection camera. I want 3 active realtor + home-inspector referral relationships by month 4 (each = 8-15 Level 2 inspections/year at $400-$600 each = $3K-$9K/year). Build me the cold-walk package for 5 brokerages + 5 home-inspector offices/week: (a) the prospect list — find 5 mid-volume realtors at Coldwell Banker / RE/MAX / Compass / Keller Williams (filter to agents with 10+ closed transactions in past 12 months), find 5 InterNACHI- or ASHI-certified home inspectors in my zip, (b) the in-person walk-in pitch I deliver Tuesday-Thursday between 11am-1pm with my CSIA cred + sample Level 2 report + COI: 'hi, I'm [name] from [my brand] — CSIA-certified chimney sweep with video inspection camera. NFPA 211 requires Level 2 inspection at every home sale + after any chimney fire — your escrows need that report. I do same-week Level 2 inspections at $400 (24-hour turnaround on the report), $25 referral fee per closing back to you. Want me to leave 25 cards + a sample report?,' (c) the home-inspector-specific pitch ('your home inspections flag 'chimney needs further evaluation' — that's Level 2 territory I do for you. $400 same-week + I copy you on every report so your client trusts your judgment'), (d) the leave-behind 1-pager + 25 cards + a sample Level 2 report (Canva: my CSIA logo, my video-inspection capability, my 24-hour turnaround commitment, my insurance proof, my Calendly), (e) the 5-day phone follow-up to the agent ('hi [first name], [my name] from [my brand] — wanted to confirm you got my cards. Any escrows closing this week that need a Level 2?'), (f) the absolute don'ts: NEVER promise 'pass guaranteed' (Level 2 reports findings — you don't pre-judge), NEVER skip the COI proof (every realtor's E&O carrier wants it), NEVER offer below $400 on Level 2 (you bleed margin once video + 24-hour turnaround is included). Tone: confident neighbor + senior CSIA sweep. Output paste-ready."

One active realtor relationship = $3K-$9K/year + zero CAC.
Level 2 video-scope inspection report template (ChatGPT + Canva + Loom AI, ~20 min/job). The video-scope report is what insurance + escrow need. Paste:

"I'm a CSIA-certified chimney sweep with video inspection. Build me the per-Level-2-inspection report template every escrow + insurance file needs (NFPA 211-cited, video-evidence-backed): (a) the report header — property address + date + escrow company + my CSIA cert # + insurance proof + contact, (b) the system inventory — chimney type (masonry / prefab metal / lined / unlined), flue dimensions, chimney height, year built (estimated), appliance type (open fireplace / wood stove / pellet stove / gas insert), (c) the visual inspection findings — exterior crown condition (intact / cracked / spalling), cap condition (intact / missing / damaged), exterior masonry condition (intact / efflorescence / step cracking), flashing condition (sealed / failing), interior firebox condition (clean / soot accumulation / refractory damage), smoke chamber condition (parging intact / missing / damaged), (d) the video-scope findings — every 12 inches of flue interior video-recorded + reviewed, creosote rating (Stage 1 light / Stage 2 moderate flake / Stage 3 glazed — different mitigation approach per stage), any structural defects (cracks, voids, missing mortar, displaced flue tiles), any obstructions (debris, animal nests, collapsed liner sections), (e) the NFPA 211 compliance findings — cite specific NFPA 211 sections for any non-compliance (e.g., 'NFPA 211 Section 12.4 requires lined flue for solid-fuel appliances — current chimney is unlined, recommend stainless-steel liner before continued solid-fuel use'), (f) the recommendations — repairs needed before continued use (specific items + estimated cost ranges), repairs recommended within 12 months, items that pass for current use, (g) the photo + video evidence — Loom AI 90-sec narrated video walkthrough for the escrow file (auto-titled + transcribed), still photos of every flagged finding, (h) the customer + tech signatures + cert # for verification, (i) the absolute don'ts: NEVER claim 'pass' (Level 2 reports findings — escrow decides), NEVER recommend a fix I do (creates conflict-of-interest concern — recommend the work, let them decide who does it), NEVER skip the video evidence. Tone: senior CSIA sweep + escrow-aware. Output paste-ready as Canva 4-page report template + Loom narration script."

The video-scope Level 2 report = the difference between $300 verbal-only and $600 escrow-ready.
CSIA cred display + photo-per-job documentation (ChatGPT, ~15 min one-time setup). CSIA + photo doc is the entire post-claim defense. Paste:

"I'm a CSIA-certified chimney sweep. Build me the cred display + photo-doc protocol: (a) the website / Google Business Profile cred block — CSIA logo (download from csia.org member portal) + my cert # + 'Find me on the CSIA Find a Sweep directory: [link],' my certification scope ('NFPA 211 Level 1, 2, 3 inspections + sweep + remediation referral'), my renewal date (3 years from pass), (b) the truck/van decal placement — CSIA badge prominent + my cert # + my Find-a-Sweep QR code (scans straight to my CSIA verification page — every truck I drive past becomes a verifiable credential check), (c) the per-job photo documentation protocol via Jobber (5-10 photos per job, attached to customer profile permanently): 1 exterior cap (proves cap condition before/after), 1 crown (proves crown condition), 1 smoke chamber pre-clean, 1 smoke chamber post-clean (proves I cleaned), 1 flue interior pre-clean (creosote stage), 1 flue interior post-clean, 1 final firebox, (d) the post-job photo-doc email I send every customer ('here are the 7 photos from today's service at [address] — keep these for your insurance file. I retain copies for [Y] years per CSIA standard'), (e) the absolute don'ts: NEVER skip a photo (a homeowner whose house burns 6 months later will sue every contractor who touched the chimney — without photos you defend with memory), NEVER skip the cert # on any official communication (it's verifiable), NEVER claim CSIA cert until I've passed the exam. Tone: senior CSIA sweep + lawyer-aware. Output paste-ready as truck decal + Jobber photo workflow + customer email template."

Photo-per-job is your free defense if a customer's chimney is implicated in a fire 18 months later. Use Jobber's photo feature on every visit.
Off-season dryer-vent + waterproofing cross-sell + summer route plan (ChatGPT, ~20 min one-time setup). May-August = 30% of revenue if you cross-sell right. Paste:

"I'm a CSIA-certified chimney sweep. Sept-Feb is 70% of revenue. I need to fill May-Aug with related services using the same skills + truck + customer list. Build me the off-season cross-sell + summer route plan: (a) the May 1st email blast to my entire customer list ('hi [first name], spring + summer is the perfect time for the work that's harder in winter: dryer vent inspection ($130, NFPA 211 fire-risk report — book before vacation season fills the dryer with extra lint), chimney waterproofing ($400-$900, prevents the freeze-thaw spalling that kills crowns), crown repair ($150-$1,200, fix small cracks before they grow). Book any of these by Memorial Day for $25 off your fall sweep'), (b) the dryer-vent add-on script I run at every off-season job ('while I'm here, want me to inspect your dryer vent? Same fire-risk lens as the chimney work. $100 add-on if same visit, $130 standalone'), (c) the waterproofing seasonal Loom (60-sec video showing what spalling looks like + how the ChimneySaver waterproofing prevents it — sent monthly May-Aug to past customers via email), (d) the property manager pitch for off-season multi-family work ('your buildings have shared chimneys + dryer exhaust stacks — quarterly rotation $300-$600/visit covers both'), (e) the August 15 ramp-up email ('hi [first name], cold weather hits in 6-8 weeks — schedule your annual sweep + inspection before September fills up. Reply with your preferred week'), (f) the absolute don'ts: NEVER discount fall sweeps to fill summer (kills your peak pricing), NEVER skip the waterproofing pitch (highest off-season margin), NEVER promise 'we won't be busy in fall' (you will be — book early). Tone: warm friend + senior CSIA sweep. Output paste-ready email blast + scripts."

Off-season cross-sell = $1,500-$2,500/month of bridge revenue Mar-Aug = the difference between $40K and $55K year-1 net.

Time Saved Per Week

Roughly 3-5 hours/week once your annual contract package, realtor partnership, and Level 2 report template are built:

Annual contract auto-renewal: 1-time setup → fires automatically every August
Realtor + home-inspector cold-walk: 1-time setup → reused on every walk-in
Level 2 inspection report: 60 min/job → 20 min (Canva + Loom AI)
CSIA cred display + photo doc: 1-time setup → fires per Jobber job
Off-season cross-sell + summer route plan: 1-time setup → reviewed annually

Trade that time for: 5 more realtor / home-inspector walk-ins, the Saturday morning re-photographing your truck signage with the cert #, and the InterNACHI / ASHI inspector breakfast where one introduction lands a year of escrow Level 2s.

Your First Win

30 minutes from now your annual contract auto-renewal automation is built in Jobber + the in-home pitch script is laminated for the truck dashboard — every Level 1 sweep customer gets the pitch starting Monday. Open ChatGPT (free tier works). Paste:

"I'm a CSIA-certified chimney sweep in [my city]. The single biggest revenue lever in this business is the annual maintenance contract — converting 50% of my Level 1 sweep customers to a $200/year auto-renewing contract turns a one-time $325 sale into a $200/year × 4-year average = $800 lifetime customer. The conversion happens at the in-home checkout (50% close rate when asked in person) — NEVER on the phone (15% close rate). Build me the complete annual contract package I deploy starting Monday: (a) the in-home pitch script I deliver at the END of every Level 1 sweep job, while I'm still at the customer's house (60-second verbal): 'You're set for this year — but want me to put you on my annual contract? $200/year covers the inspection + sweep, billed every August so I'm on your calendar before the cold weather hits. I save your card now, you don't think about it again until I text you a week ahead. Total over 4 years = $800 vs. $325 × 4 = $1,300 — saves you $500. Want me back next August?,' (b) the 3 objection responses — 'I might move' ('contract transfers to your new address OR you cancel anytime, no fees'), 'I don't use the fireplace much' ('NFPA 211 still recommends annual inspection — wood-burning or not, an unswept flue + an active liner = creosote/animal/water issues that compound'), 'Let me think about it' ('totally — I'll text you the link tomorrow with a 7-day window to lock today's price before next year's rate goes up'), (c) the 1-page annual contract sell-sheet (Canva: my CSIA badge + cert #, the 4-year value math, the 'I call you a week ahead' commitment, the cancel-anytime clause, my insurance proof, my Calendly QR), (d) the Jobber automation that fires August 1st every year — text + email auto-sent to every annual-contract customer ('hi [first name], it's August — your annual contract chimney sweep is coming up. I'll be at [address] [date] at [time] — reply C to confirm, R to reschedule, X to cancel. Card on file billed $200 the morning of the visit'), (e) the post-sweep annual recap email auto-sent every December to every annual-contract customer ('hi [first name], here's your [year] chimney service summary: [date] sweep + Level 1 inspection completed, creosote rated [Y] (light/moderate/heavy), photos attached for your insurance file, NFPA 211 compliance status, your renewal is August [year+1] — card on file unless you cancel'), (f) the absolute don'ts: NEVER pitch the annual contract on the initial booking call (kills trust — pitch only AFTER I've completed the Level 1 work in their home), NEVER discount below $150/year (you bleed margin), NEVER skip the December recap (it's why renewal sticks for 4+ years), NEVER auto-bill more than $25 above the stated rate without 30-day notice. Tone: warm friend + senior CSIA sweep. Output paste-ready as Canva sell-sheet text + Jobber automation flow templates + the laminated in-home pitch script for my truck dashboard."

Set it up Sunday afternoon. Use the in-home pitch on every Level 1 sweep starting Monday. 50% conversion × 12 sweeps in your first peak month = 6 annual contracts × $200/year = $1,200/year of locked-in revenue from one weekend's setup work — and that compounds every August for 4+ years.

Product / Service Offering

You sell three things. The Level 1 sweep gets people to call. The annual contract turns one-time customers into a real business. Level 2 inspections are the highest-margin job and pay your rent in slow months.

Core offerings (typical residential ranges per Angi chimney cleaning cost guide and HomeAdvisor chimney inspection cost):

Level 1 inspection + sweep (one-time): $250-$400. Visual inspection of accessible portions, full sweep with rotary loc system, vacuum all debris, photo report. 60-90 minutes. Your front door.
Annual maintenance contract: $150-$250/yr for inspection + sweep, billed yearly on the saved card. Cheaper per visit than the one-off — but you've locked in the customer for 4-5 years. The actual business.
Level 2 inspection (real-estate transaction or post-event): $300-$600. Required by NFPA 211 when a home is sold, after a chimney fire, or after a major weather event. Includes a video camera scan of the flue interior. The agent or inspector usually pays out of escrow.
Add-ons (where the real margin lives): chimney cap install $150-$400, crown repair $150-$1,200, waterproofing $400-$900, dryer-vent cleaning $100-$200, smoke-chamber parging $400-$800.

Pricing model: Charge a flat rate per service. Never hourly. Annual contracts auto-renew on the saved card every August so you book the September-November rush before it hits. Use Square or Jobber for the saved-card setup. Take payment at the end of the visit.

Revenue Model

Chimney sweeping is the most seasonal cleaning job there is. Roughly 70% of revenue lands between September and February, per CSIA member surveys (Chimney Safety Institute of America). Use peak to load annual contracts that bill year-round, and stack dryer-vent and waterproofing in May-August.

Unit economics (peak month, October, year 1, solo sweep, as of 2026):

Line item	Amount
22 Level 1 sweeps × $325 avg	$7,150
4 Level 2 inspections × $450	$1,800
6 chimney cap installs × $275 blended	$1,650
3 dryer-vent add-ons × $135	$405
Gross revenue	$11,005
Cap parts + supplies (rods, brushes, drop cloths)	-$1,100
Mileage (~900 mi @ $0.40/mi)	-$360
Square processing (2.6% + 15¢, 2026 rate per Square pricing)	-$290
Jobber Core ($29/mo prepaid annual, 2026 rate per Jobber pricing)	-$29
Liability insurance + bond (blended monthly)	-$95
Net (peak month)	~$9,131

A slow June looks different — 6 dryer-vent jobs at $135, 2 waterproofing jobs at $650, 4 annual-contract billings at $200, roughly $3,110 gross. Year 1 blended: $40-$55K net.

Path to your first $5K month (peak season): 16 Level 1 sweeps plus 2 Level 2 inspections plus 3 cap or crown add-ons. About 18-20 service days — full-time, but only 6 months of the year.

Path to your first $10K month (peak season): Add 4-5 annual contracts billing that month plus a second video inspection per week, or hire a part-time W-2 helper for dryer-vent and basic sweeps while you take Level 2 work. Two pairs of hands in October-November is the difference between $9K and $14K. Run the numbers before you hire — labor, comp, and payroll tax can eat 30-40% of what your helper brings in.

Note on LLC fees: California is $70 plus an $800 annual franchise tax (waived first year for LLCs formed 2024+). Texas is $300, no annual fee. Florida is $125 plus $138.75/yr. Full state-by-state list at LLC University 50-state table.

CSIA certification — get it. Roughly $700 all-in. Not legally required, but homeowners search for "CSIA certified" specifically and insurers want a CSIA-certified report on file. The single highest-return purchase on this list.

Legal & Formation

Business entity. Form an LLC (limited liability company) before your first paying job. Chimney work is risky — you're on a roof, dealing with fire-hazard buildup, and a bad inspection report can land you in court when a house burns three months later. A sole proprietorship gives you zero personal-asset protection. If money's tight, run as a sole prop for 30 days while you confirm 5 paying jobs, then file the LLC. Don't skip liability insurance during that window — the $1M / $2M policy is what actually covers you, not the LLC.

Licenses & permits. No federal license. State licensing is rare for chimney sweeps — Oregon and Washington require a general construction-contractor registration, but most states don't. Look up your city or county general business license (most require one, $25-$100/yr) on your municipal clerk's site. CSIA certification isn't legally required, but functionally it's the credential homeowners and insurers ask for. Exam is run by the Chimney Safety Institute of America — one weekend of study, half-day exam.

EIN. Apply free at IRS EIN Online. Apply free at IRS — never pay a third party.

Fire-and-safety standards to know. NFPA 211 is the chimney standard — annual inspection minimum, three inspection levels, triggers for Level 2 (sale, fire, weather event, fuel change). NFPA 90A covers ventilating systems and applies if you add dryer-vent cleaning. Reference both in your service contract.

Labor & employment. Calling a helper a 1099 contractor (independent contractor — you don't withhold tax or carry workers' comp) when they should be W-2 (employee — you withhold tax and carry workers' comp) is the biggest legal risk for any service business. Federally, the DOL economic-realities 6-factor test governs. The 2024 rule isn't enforced administratively as of May 2025, but plaintiffs can still sue you under it. California's 2020 worker-classification law (AB5) uses a 3-prong "ABC" test nearly impossible for a sweep business to pass — sweeping IS what a sweep business does. Once you have one W-2 employee, workers' comp is mandatory in CA, NY, PA, IL, OH, MI, and most other states. Florida requires it at 4 non-construction employees. Texas is the only state where private employers can opt out. Homeowner policies don't cover injured workers — the standard homeowner contract (the ISO HO-3 form) excludes trade-employee work injuries.

Sales tax. 17 states plus DC tax cleaning services per ISSA. California doesn't tax cleaning. Texas taxes chimney and duct cleaning (Texas Comptroller Pub 94-111). Florida taxes commercial cleaning but not residential. Pennsylvania taxes building cleaning at 6% state, including chimney (61 Pa. Code § 60.1). New York taxes interior cleaning.

Marketing & First Customers

Chimney work is intensely local and intensely seasonal. By the time someone smells smoke in their living room, they're calling whoever ranks first on Google. Skip paid lead aggregators in your first season. Thumbtack charges $15-$50 per cleaning lead (Thumbtack help) and Google Local Services Ads average $28/lead (LocaliQ) — fine for a year-2 sweep with reviews, brutal for a brand-new one.

Channels that work for this idea:

Google Business Profile + LSA (Local Services Ads) — claim your free Business Profile in week 1, then turn on the "Google Guaranteed" badge once you have 5 reviews. The badge moves you to the top of "chimney sweep near me" and converts at 2-3x organic listings.
Real estate agent partnerships — find 3-5 mid-volume agents at your local Coldwell Banker, Compass, or Keller Williams office. Offer same-week Level 2 inspections at $400. One agent can send you 8-15 inspections a year.
Property inspector partnerships — home inspectors flag the chimney "needs further evaluation" but don't do the inspection themselves. Drop cards at every InterNACHI- or ASHI-certified inspector in town. Offer a $25 referral fee per booking.
Nextdoor Business — free Business Page plus ~2 free posts a month. Paid Neighborhood Sponsorships run $32-$150/month per zip per Nextdoor for Business. Post about creosote risk in late August.
Door hangers in 2-3 zip codes (older neighborhoods) — print 500 at GotPrint or Vistaprint (~$80) and walk neighborhoods built before 2000. Hit them in late August so the offer's on the fridge when the first cold snap arrives.

Your first 10 customers. Two plays in parallel. Post on Nextdoor and 2-3 local Facebook groups in late August: "CSIA-certified chimney inspection + sweep, $199 for first 10 households (normally $325) — booking through October." The discount converts these into annual contracts on the spot. Walk into 5 real estate offices and pitch the $400 same-week Level 2 deal directly. Agents hand you their cell for the next escrow that needs an inspection.

Week 1-2 — Sign up for the CSIA certified sweep exam. Block a Saturday for the test. Your first 6 months of marketing hinges on this credential.
Week 1 — Get quotes from Hiscox, Next Insurance, and Thimble for $1M / $2M liability plus a $10K bond. Pay annual upfront. Mention "chimney sweep" — some carriers won't quote roof work without an add-on.
Week 2 — Buy the starter kit: rotary loc system, rods, brushes ($400-$600), HEPA chimney vacuum ($250-$500), drop cloths, ladder + harness. Skip the video camera until week 5.
Week 3 — Set up Square (free, $0/mo) and a Jobber 14-day trial. Get a business line through Google Voice ($0) or OpenPhone (~$15/mo). Don't use your personal cell.
Week 4 — Pass the CSIA exam. Add the badge to your website, Google Business Profile, truck signs, door hangers. Target: certified, insured, equipped — spend $3,500-$6,000.
Week 5 — Buy the entry-level video inspection camera ($500-$1,200). Required for Level 2 jobs, your highest-margin work.
Week 6 — Walk 5 real estate offices and 3 home-inspector offices. Pitch $400 same-week Level 2 inspections, offer the $25 inspector referral fee. Target: 1-2 agents send you their next escrow chimney.
Week 7 — Print 500 door hangers and walk 2-3 zip codes with older single-family homes. Post the "$199 first inspection + sweep" promo on Nextdoor and 2 Facebook groups. Target by week 8: 4-6 booked Level 1 sweeps, ~$1,200-$2,000 cash.
Week 9 — Convert completed sweeps into annual contracts. At checkout: "Want me back next August for $200/yr? I'll save your card and call you a week ahead." Target: 50% conversion to annual.
Week 10 — Open a separate business checking account (Mercury, Bluevine, or a local credit union). Mixing personal and business creates a tax mess.
Week 12 — File your LLC if you haven't, apply for the EIN. Switch Square to the LLC's EIN. Target: ~$5-$8K booked for the rest of peak + 8-12 annual contracts on file.

Common Pitfalls

Quoting hourly instead of flat-rate. Hourly punishes you for being good at your job — clean fast, earn less. Fix: Quote a flat per-service rate after a 5-minute walkthrough or video tour. Always.

Skipping CSIA certification because it costs $700. Without the badge, you compete on price alone, and homeowners with money won't call you. Fix: Pay for the exam in week 1, before your first paying job. The $700 pays for itself in two upgraded annual contracts.

Treating every job as one-and-done. A one-time $325 sweep where you don't ask about an annual contract is the same customer who'll Google "chimney sweep near me" next year and call someone else. Fix: At every checkout, offer the annual contract. Save the card. Auto-bill in August.

Ignoring summer. May-August is slow if you only sell sweeps, and fixed costs don't pause. Fix: Add dryer-vent cleaning ($100-$200), waterproofing ($400-$900), and crown repair ($150-$1,200). Same skills, same truck, same customer list.

1099-ing your first helper — especially in California. Calling a helper you control day-to-day a 1099 is the most-litigated issue in service businesses. Plaintiffs sue under the federal economic-realities test; California's AB5 ABC test is nearly impossible to defend. Fix: Hire W-2 from day one. Carry workers' comp. Cheaper than the lawsuit, and roof-fall claims bankrupt uninsured small businesses.

Not photographing every flue. A homeowner whose house burns in February will sue every contractor who touched the chimney in the last 18 months. Without before-and-after photos, you're defending with memory. Fix: Use Jobber's job-photo feature every visit. 5-10 photos per job — exterior, cap, smoke chamber, flue interior, final firebox. Attach to the customer's profile. Free defense.
