Chimney Sweeping Services on Long Island

Regular chimney sweeping is the single most important thing you can do to protect your home from chimney fires and carbon monoxide poisoning. The Chimney Safety Institute of America (CSIA) and the National Fire Protection Association (NFPA 211) both recommend annual chimney inspections and cleaning for all fuel-burning appliances.

At Capstone Chimney, our Long Island chimney sweeping service goes far beyond a simple brushing. We use professional-grade rotary cleaning systems combined with high-definition video inspection cameras to ensure every square inch of your flue is clean and structurally sound.

Creosote, the primary byproduct of wood combustion, accumulates in three stages. Stage 1 is a light, flaky deposit easily removed by brushing. Stage 2 is a dense, tar-like buildup that requires more aggressive cleaning. Stage 3 creosote is a glazed, hardened coating that is extremely difficult to remove and highly combustible. Our sweeping service addresses all three stages.

Beyond creosote removal, our technicians check for animal nests, leaves, and other obstructions that can block proper ventilation. We inspect the flue liner for cracks, gaps, and deterioration that could allow heat transfer to combustible materials in your walls. We examine the damper operation, smoke shelf condition, and firebox integrity.
