Duct Cleaning & Sealing

Not every home needs its ducts cleaned every year — but if yours were dirty during a renovation, had rodents, or smell musty at startup, it's the right call. We use NADCA methods and leave your system tighter than we found it.

Our process

What happens after you call

No dispatch runaround, no upsell script. Here's exactly how we work.

01

Access inspection

We inspect duct interiors with cameras before we quote. If they're clean, we tell you.

02

Contain & clean

Negative-air machine plus rotary brushes; we contain debris rather than blowing it into your home.

03

Optional sealing

Aeroseal seals ducts from inside, often cutting leakage by 60–80% — measurable on a duct blaster.

FAQ

Duct Cleaning & Sealing — common questions

No. Most homes need it once every 5–10 years. If a company is pushing annual cleanings, that's a red flag.

Only if your ducts are visibly dirty. A media filter upgrade often does more for allergies than cleaning.

A UL-tested duct sealing system that atomizes sealant inside the ductwork. Great for leaky, buried, or hard-to-access ducts.
