Learn moreDryer Vent Cleaning
Clogged dryer vents are one of the leading causes of house fires in the US — the NFPA reports nearly 15,000 dryer fires per year. Lint buildup in the vent duct restricts airflow, overheats the dryer, and creates a serious ignition risk.
We clean the full duct run from your dryer to the exterior vent cap, clear any blockages, and check the vent path for kinks or damage that reduce efficiency and increase fire risk. Fast to schedule, quick to complete — most vent cleanings take under an hour.

See Exactly What's in Your Flue
We use professional camera inspection equipment to run a live feed through your flue so you can see the condition of your liner, firebox, and chimney structure. No guessing, no vague reports — you see what we see. This is standard on all our inspections.

Learn moreNot the “$89 Chimney Cleaning” Company
You've probably seen the ads: “$89 chimney cleaning, book online!” The crew shows up, declares your chimney dangerously unsafe, and suddenly the bill is $600+. This bait-and-switch is a known and widespread problem in this industry. Here's how we operate differently.
What scam companies do
- ✗Advertise an impossibly low price to get in the door
- ✗Send rotating crews or unlicensed subcontractors
- ✗"Find" urgent problems and pressure you to decide on the spot
- ✗Refuse to show you evidence or explain the repair
- ✗Charges balloon after the work starts
What to look for
- →Licensed and insured — ask for documentation
- →Camera footage so you see conditions yourself
- →Written estimate before any work begins
- →No pressure to approve repairs on the spot
- →Owner or named contractor who stands behind the work
