Windows and doors in Cornwall Park.

The neighborhood around Cornwall Park, the big wooded park on the north side, is a settled family area of mostly mid-century homes from the 40s through the 70s. A lot of these houses still have their original aluminum sliding windows and sliders, which were standard in that era and are terrible at holding heat: the metal conducts cold, the single glazing sweats, and the rollers wear out. The common job here is trading those tired aluminum sliders for energy-efficient vinyl or fiberglass units.

Cornwall Park homes also tend to back onto green space or a generous yard, so adding or upgrading a patio door to open the kitchen or family room to the backyard is a popular project. We replace old aluminum sliders with smooth-gliding, tight-sealing patio doors, tempered and Low-E, and fix whatever the old door hid in the opening. Window replacement, patio doors, and the occasional egress window for a finished basement are the steady work here.
