Duct Cleaning Case Studies: Real Homes, Before and After

Every write-up here is a job we actually did in a St. Louis-area home. You see why the homeowner called, what we found inside the ducts, and what we did about it.

No two duct systems are alike, so no two write-ups read the same.

What we found

The condition of the ductwork and blower once we opened the system up, shown in before photos.

What we did

The cleaning, sanitizing or dryer vent work completed, with after photos from the same spots.
