How to Start a Dryer Vent Cleaning Service From Home

ByGarage Business Blueprint

Dryer vent cleaning is a simple, repeatable service you can run from home with a modest kit and a vehicle.

Why the Work Matters

The U.S. Fire Administration’s report on 2008–2010 data estimated about 2,900 clothes dryer fires in residential buildings each year, causing about 5 deaths, 100 injuries and $35 million in property loss annually.

Failure to clean was the leading factor, at 34% of those fires. Fires peaked in January, and the report found more of them in fall and winter.

Equipment and Rough Costs

Prices below are retail listings as of October 2026 and will vary.

  • Rotary brush kit: Home Depot listed the Gardus LintEater Jr. kit at $16.35, and True Value listed the 10-piece LintEater system at $46.99. These are homeowner-grade; longer runs call for sturdier rod systems.
  • Vacuum: A shop vacuum to catch loosened lint at the dryer end.
  • Manometer or airflow meter: Useful for before-and-after readings. TEquipment listed entry-level digital manometers from Fieldpiece and Testo at $186.15, with Dwyer models from about $213 to $284.
  • Ladder: An extension ladder in good condition for second-story and roof terminations.

Certification, Licensing and Insurance

The Chimney Safety Institute of America offers the Certified Dryer Exhaust Technician (C-DET) credential, which it calls the only nationally recognized credential for dryer vent cleaning. You can qualify through a three-day workshop, a one-day review or an online review, each followed by an exam. CSIA lists a $100 online renewal fee as of April 1, 2026.

Licensing and insurance rules vary by state, county and city, so check locally. General liability insurance is worth pricing before your first job, since you’ll be working inside other people’s homes.

What to Charge

HomeAdvisor’s cost guide, updated June 17, 2026, puts the national average at $145, with most jobs between $104 and $188. It lists roof vents at $150 to $250 and heavy blockages such as bird nests at $120 to $250. Treat these as reference points, not guaranteed rates.

Finding Customers

  • Realtors and home inspectors who flag clogged vents before a sale.
  • Property managers with many units on one schedule.
  • Seasonal reminders in fall and winter, when the USFA data shows dryer fires climb.

Safety and When to Refer Out

  • Ladders: OSHA advises setting extension ladders at a 4-to-1 angle, extending them three feet past the landing, keeping three points of contact and staying 10 feet from power lines.
  • Roofs: Skip steep, wet or fragile roofs unless you have proper fall protection.
  • Rodent nests: The CDC says not to sweep or vacuum droppings dry. Wear gloves, soak the material with disinfectant or a fresh bleach solution and let it sit for about five minutes before removing it.
  • Gas dryers: CSIA notes that blocked vents can trap carbon monoxide from gas dryers. Leave gas line disconnection and any gas smell to a licensed gas technician or the utility.
  • Damaged or plastic ducts: CSIA notes plastic transition ducts are flammable. Recommend metal replacements, and refer rerouting or in-wall repairs to a qualified contractor if that’s beyond your skills.
