Stop Window Leaks Before They Cause Damage
At Leak Stoppers Inc, we specialize in window leak detection and repair across Suffolk County, Nassau County, and all of Long Island, ensuring your home stays dry and protected.
Window leaks are one of the most common homeowner complaints, but the truth is most window leaks aren’t caused by the window itself. Water intrusion around windows can come from roofing, gutters, or skylights above, or from poor caulking and clogged weep holes below.

Why Window Leaks Happen
Understanding the source of a leak is critical. Common causes include:
- Leaks at the top of a window – often caused by roofing, gutter, or skylight issues above.
- Leaks at the bottom of a window – usually due to poor caulking on replacement windows or clogged weep holes in vinyl sills or storm windows.
- Wind-driven leaks – water intrusion that only occurs when rain is blown against the wall or window in a certain direction.
- Flange vs. caulked windows – Flange windows (Anderson, Velux, etc.) rely on house wrap to keep water out, while vinyl replacements depend on the existing frame and caulked seams, which can fail over time.
By analyzing the frequency and location of leaks, our experts determine whether the problem is with the window, wall, or roof system.
