Creosote Removal in Queens & Long Island
Creosote is the tar-like residue wood smoke leaves inside the flue, and it's highly flammable. Light, flaky buildup comes off with a sweep; hardened or glazed creosote needs specialized tools or chemical treatment.
What is creosote removal?
Creosote is the residue wood smoke leaves on the inside of the flue. It's commonly described in three stages: first-stage is a light, flaky soot; second-stage is crunchy, tar-like flakes; third-stage is a hard, shiny glaze that's very difficult to remove and highly flammable.
First-stage creosote comes off with a normal sweep. Second- and third-stage buildup needs more aggressive mechanical tools or chemical treatments that convert the glaze into something that can be swept out.
Warning signs
- Thick black buildup visible above the damper
