Dryer Vent Cleaning Service
The fire-prevention business nobody thinks about until it's too late
Bottom line
Accessible entry point; validate local supply before buying.
Dryer vent cleaning is a $1.5B industry that most people have never heard of — yet the NFPA reports clogged dryer vents cause 15,000+ house fires per year in the US. A one-person operation can run 6–10 jobs a day at $100–$200 per job using a van, a rotary brush kit, and a pressure blower. Margins are exceptional because there's almost no cost of goods. Franchises like Dryer Vent Squad have validated the model; the real money is in building a recurring customer base (annual cleanings) and layering in multi-unit residential contracts.

How It Works
Technicians use rotary brush systems and high-powered blowers to clear lint buildup from residential and commercial dryer ducts. Most jobs take 30–60 minutes and are priced flat ($100–$200 residential, $300+ commercial). Recurring annual maintenance contracts create predictable revenue. Add-on services like vent rerouting or bird guard installation improve ticket size.

Source: SBA 7(a) FOIA dataset, filtered to acquisitions (loans where business age is "Change of Ownership"). Implied deal size assumes an 85% loan-to-purchase ratio, a common SBA change-of-ownership structure. Charge-off rate shown only when 10+ loans have resolved (paid in full or charged off). Interest rates reflect last 24 months only. Actual deal values vary with equity injections, seller financing, and working capital terms.
Pros
- +Near-zero cost of goods — labor and a $5K equipment kit is all it takes
- +Built-in urgency: fire risk creates real demand that doesn't need much selling
- +Recurring model: customers need annual cleanings, creating a loyalty loop
- +Low competition — most markets are fragmented and underserved
- +Multi-unit residential and property management contracts scale fast
Cons
- -Seasonal dips in some markets (though indoor service is year-round)
- -Solo-operator cap: you can only run so many jobs per day without hiring
- -Booking friction — most customers don't know they need it until you educate them
