What questions should I ask before hiring a dryer vent cleaner?

Ask: (1) what's the flat price and what's included, (2) do you use rotary brushes and HEPA vacuums (not just compressed air or a leaf blower), (3) will you provide before/after documentation, (4) are you fully insured with proof available, and (5) will you diagnose and quote any repairs before starting work.

1. Flat price and what's included. Reputable companies quote a flat inspection fee and a clear cleaning price, with inclusions listed: exterior hood, interior connector, full vent run, booster fan if any, written report. Vague 'starting at' pricing with open-ended add-ons is a red flag.

2. Method. Professional vent cleaning requires a rotary brush sized to your vent diameter plus a HEPA-filtered vacuum at the dryer end. 'Air-only' cleaning (compressed air or leaf blowers) can compact lint further and send it into walls. If the answer is anything but rotary brush + HEPA vacuum, keep looking.

3. Documentation. Before-and-after video (or at minimum photos) plus a written inspection report is standard — you should be able to see what was there and what it looks like now. Without documentation, there's no way to verify the work or file it with insurance.

4. Insurance. Ask for a current certificate of insurance before the appointment. Reputable providers have a standard COI template they can email in minutes. If they resist or delay, that's a signal.

5. Repairs. Some vents need more than cleaning — a damaged exterior hood, a collapsed flex duct, a missing booster fan. A trustworthy pro inspects first, quotes any needed repairs before starting, and lets you decide. Surprise-charge 'we found something while we were in there' is a pattern worth avoiding.

How much does dryer vent cleaning cost in North Jersey?

The Dryer Guys charges a flat $49.99 inspection fee and a $220 routine cleaning for standard residential vent runs — a typical total of $269 plus tax. Pricing is the same across all 11 of our North Jersey service towns. Multi-unit and commercial work is quoted separately after a walkthrough.

Are DIY dryer vent cleaning kits effective?

DIY kits work well for short, straight vent runs under 10 feet with one or fewer elbows, and for clearing the connector behind the dryer. They're significantly less effective on long runs, multi-elbow configurations, or roof-terminating vents — where rotary power and professional-length brush rods plus HEPA vacuum capture make a real difference.

Is dryer vent cleaning worth the cost?

Yes — for most households, annual dryer vent cleaning pays for itself in reduced energy use, extended dryer lifespan, and meaningful fire-risk reduction. The NFPA identifies failure to clean as the leading factor in the 13,000–15,000 home dryer fires reported to U.S. fire departments each year.
