Window and Door Installation in Westport, CT

Homeowners in Westport, CT call Mosquera Construction when windows and doors need a carpenter, not a sales pitch. Westport work runs from single windows to full-house replacement and new entry doors.

Most Westport homes are shingle-style homes, antique colonials, and coastal contemporary houses, many of them predating 1940 and renovated since. Window work here starts by checking how much the opening has moved and whether the sill is still sound.

Around Compo Beach, Saugatuck, Greens Farms, and Coleytown, houses tend to have antique wood windows next to large glass on coastal contemporary houses. Many projects end up as sliding and swinging patio doors facing the water, plus window replacement.

In Westport, windows and doors have to survive salt spray and wind-driven rain on elevations facing the water. Flashing and sill details are where that battle is won.

Window Replacement Done Right in Westport Homes

On Westport windows, water gets in around the unit, not through it. Proper flashing and a sill pan are what stop it.

Insert replacement works when the old frame is sound. Once rot reaches the sill or jamb, full-frame replacement is the only honest option.

Exterior doors fail at the sill and the bottom of the jamb. Those get repaired before the new unit goes in, then sealed and trimmed.

The goal is a window that looks like it belongs. Trim profiles inside and out are matched to the existing Westport home.

It depends on the number of openings, unit type, and what we find behind the trim. We don't quote by phone, because the number would be wrong. The visit and the written estimate are free.

Same-size replacement often doesn't need one, but enlarging an opening or adding a door does. In Westport that goes through the Town of Westport building department. We confirm before scheduling.

It depends on the frame. If the sill and jambs are solid, an insert works. If there's rot or the opening has moved, full-frame is the right call. We'll tell you after we look.

Yes. We swap one opening at a time and close it right away, so heat loss stays minimal. The sealants and flashing we use are rated to cure in cold weather.
