Professional window & door leak repair serving Chelsea and surrounding areas.
On the Chelsea side of the Mystic, rain rarely falls straight down when it matters. Nor’easter wind drives water sideways into window perimeters across the city’s wooden triple-deckers and century homes — and perimeters fail by pattern: flashing that gave up decades ago, perimeter seals dried to powder, and trim boards taking the storm full in the face. Window leak repair in Chelsea means finding which layer failed — seal, flashing, or the opening itself — and rebuilding the window’s defense before the next wind-driven rain. Water Damage Pros US repairs leaking windows across Chelsea and Suffolk County, including the interior damage the leaks leave behind.

| Full replacement with flashing | $900 – $2,500 | Per window, flashed correctly |
| Interior plaster + paint restoration | $400 – $1,500 | Included when opened for repair |
A window leak is a season problem, not a one-storm problem. The perimeter that let nor’easter water in this March lets January’s freeze-thaw in next — and every cycle wets the cavity a little deeper. Fix the layer that failed while it’s still a flashing job, not a wall rebuild.
