Chimney Sweep & Repair in Islip, NY

Chimneys in Islip have a story.

Islip (ZIP 11751) sits in the Town of Islip on the Great South Bay, and the housing stock reflects two distinct eras. The interior neighborhoods — Oak Street corridor, around the Islip LIRR station, and north toward the highway — are predominantly post-WWII cape cods and ranches built between 1948 and 1968. These homes were constructed with standard clay tile-lined chimneys, and after 60-plus years roughly 55% of inspections we run here show liner cracking or spalling that requires relining. Waterfront homes south toward the Bay and along the Connetquot River face intensified exposure: salt air accelerates mortar joint erosion, crown cracking, and cap deterioration faster than inland locations. We see more crown work and waterproofing requests per inspection in Islip than almost anywhere else in Suffolk. Chimney cap replacement ($199–$349) and crown coat application are frequent first steps before addressing the liner. Full liner replacements in Islip typically run $1,900–$2,700 depending on chimney height and flue count. Permits for chimney work go through the Town of Islip Building Division — standard residential chimney liner work is generally exempt from permit requirements, but full rebuilds and new installations require Town of Islip approval, typically a 7–10 business day review. We handle all permit paperwork included in the project price.
