Creosote removal is a specialized service for East Islip homeowners whose chimney has developed second or third-degree creosote buildup that standard annual sweeping cannot fully address. Third-degree creosote — a hardened, tar-like glaze that bonds to the flue liner surface — is the most dangerous and most difficult to remove. It is the primary fuel source for chimney fires, burns at temperatures exceeding 2,000 degrees Fahrenheit, and can destroy a clay tile liner in a single event. DME Maintenance performs professional creosote removal in East Islip, NY and throughout Suffolk County, NY.
Our service area covers all of East Islip and the neighboring communities. Homeowners across East Islip have relied on DME Maintenance, a local Long Island-based chimney company, for annual chimney service for over two decades.
Creosote builds faster in East Islip homes that burn green or unseasoned wood, use low-burning smoldering fires, have oversized flues, or operate fireplaces with restricted air supply. First-degree creosote — light and flaky — is removed routinely in annual sweeping. Second-degree creosote — thicker, shiny, and harder — requires more aggressive rotary cleaning methods. Third-degree creosote requires a chemical treatment protocol applied to the glaze before mechanical removal can be effective. We assess the stage of buildup on every inspection and use the correct method for what we actually find.
