Window replacement in Hillsborough
Hillsborough is a town of large, architect-built homes, and the windows are central to how each one looks: leaded and divided lites on the Tudors, arched and steel-framed glass on the Mediterraneans, big clean openings on the moderns. When those windows are decades old they cost real money in lost heat and let in road and grounds noise, but replacing them is as much a design job as an efficiency one. We work in wood and wood-clad with the right profiles, divided-lite patterns, and hardware so the new windows read as original.
Hillsborough has no commercial district and strict architectural review for a reason: the town protects its look, and we respect that. We match proportions and sightlines, prepare the design-review submittals, pull the permit, and coordinate cleanly with your architect, designer, or builder when there's one involved.
On the grounds, the work is careful and unhurried, with floors and landscaping protected and the site left exactly as it was, only the home is warmer, quieter, and sealed tight. Most projects run on a planned schedule around the size of the home and the glass.
