Windows for Cambridge Homes
Homes in Cambridge are late nineteenth-century multifamily stock under local historic protection, interleaved with much-modified postwar construction, 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 Cambridge Properties Actually Need
- The housing stock here
- Triple-deckers and Victorians here have rear porch stacks that carry three floors of egress, and those structures are the most common serious defect found on inspection.
- Working on the site
- Setbacks are measured in inches, so most exterior work happens from staging erected over a neighbour s ground by agreement.
- Permits and inspections
- Historic and neighbourhood conservation districts cover much of the city, and exterior change is reviewed before permit.
What Goes Wrong in Greater Boston
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.
