Creosote Removal & Fire Safety in Mercer Island
Even in well-appointed homes, wood-burning fireplaces build creosote, and Island owners who enjoy evening fires through the season are no exception. We grade creosote Stage 1 through 3 and remove even hardened glaze with rotary tools or chemical treatment, flue by flue.
After a chimney fire, or if you spot thick black glaze, stop burning that fireplace and call us. We run a Level-2 camera inspection to confirm the liner and custom masonry are intact, then clean and certify the system before you relight.

Creosote Removal & Fire Safety — your questions
How do I know which of my fireplaces has a creosote problem?
We inspect each flue separately and grade the buildup in every one, so you know exactly which fireplace is safe to use and which needs Level-2 cleaning.
What should I do after a chimney fire?
Stop using that fireplace and book a Level-2 inspection. Fires crack liners and tiles, and on custom masonry the damage can be costly if you keep burning. We confirm it's safe before you relight.
Does a gas fireplace produce creosote?
No, gas doesn't produce creosote, but it produces corrosive condensate. So we still inspect gas flues annually — just for different problems than wood-burning ones.
