Chimney Inspection & Sweeping

Chimney Cleaning & Inspection in Portland & Seattle — Safe Fires Start Here.

Don't Let Your Chimney Become a Fire Hazard.

Every time you use your wood-burning fireplace, creosote — a flammable black residue — builds up on the inside walls of your chimney. Left unchecked, it’s one of the leading causes of chimney fires. In addition, debris, bird nests, and structural damage can block your flue and send dangerous carbon monoxide back into your home.

NW Duct & Chimney provides thorough chimney sweeping and inspection services for Portland and Seattle homeowners. Our certified technicians clean your flue, remove creosote and debris, and inspect for cracks, blockages, and damage — so you can enjoy your fireplace with complete peace of mind.

Frequently Asked Questions

How often should I have my chimney cleaned?

The National Fire Protection Association recommends annual chimney inspections and cleaning at least once a year if you use your fireplace regularly.

What is creosote and why is it dangerous?

Creosote is a tar-like byproduct of burning wood. It coats the inside of your chimney and is highly flammable — it’s the primary cause of chimney fires.

What does a chimney inspection include?

Our inspection covers the firebox, flue liner, damper, smoke chamber, chimney cap, and exterior masonry. We check for cracks, blockages, and damage.

Do you service gas fireplaces too?

Yes. If we find damaged sections, bird nests, or improper routing, we can repair or replace the ductwork on the same visit.
