Windows for Westford Homes
Homes in Westford are antique farm housing on large parcels, with newer custom builds occupying what used to be orchard, which means window openings are rarely square and almost never a stock size. We deal with that by measuring every opening individually rather than ordering off one number and forcing the difference with trim.
A good window installed badly performs worse than a cheap window installed well. The flashing, the shimming, and the air sealing are the job - the unit itself is just a product.
What Westford Properties Actually Need
- The housing stock here
- Subdivision homes on rolling ledgy ground here have decks and patios that have settled unevenly because footings hit rock at different depths across one structure.
- Working on the site
- Grade can vary sharply within a single lot, which changes footing design across one project.
- Permits and inspections
- The town inspects footing depth on site rather than accepting the drawing.
What Goes Wrong in the Nashoba Valley
Windows that don’t operate
Units racked out of square during installation bind, stick, and never seal properly against the weatherstrip.
Water damage behind the trim
Missing or reversed flashing sends water into the wall cavity, rotting the sill and studs invisibly for years.
Drafts and cold spots
Unsealed gaps around the frame let conditioned air out all winter, and no amount of heat fixes a bad install.
