Why West Islip Homeowners Choose Us
West Islip is a desirable South Shore community with excellent schools and a housing stock of 1960s and 1970s split-levels and hi-ranches. These home styles typically have many small windows across multiple levels, making whole-house replacement projects particularly impactful for energy savings. Our West Islip installations often include basement hopper window replacements and custom-sized windows for split-level stairwell areas that are difficult to fit with standard sizes.

“Our split-level had 18 different window sizes across three levels including the basement hoppers. They measured everything precisely and every window fit perfectly. The stairwell windows were especially tricky but they nailed it.”— Carol A., West Islip
