Expert Windows in Billerica, Massachusetts

The three we see most often here: sash cords and weight pockets that were foamed solid by a previous installer; double-pane units from the nineties with blown seals and permanent fogging; and rotted sills under windows that were flashed poorly the first time. Locally, aging clapboard siding comes up repeatedly on colonial revivals.

We work out of Charlton, 19 miles away — roughly half an hour. That matters mostly for the unglamorous parts: getting back out for a warranty call, or being on site when the inspector is.

Plan on one to three days for a typical whole-house replacement. Middlesex County weather does move schedules — the full New England temperature range, from below zero in January to the low nineties in July is the usual reason — so we build a weather margin into the date we give you rather than promising one we cannot hold.

It gets photographed and shown to you the same day. Because the repair rate is already agreed, finding rot changes the invoice by a known amount rather than an argued one.

Sometimes. On a colonial revivals we can often match a single elevation closely enough that it reads as original. Where the existing material has faded past matching, we will say so rather than sell you a repair you will be unhappy with.
