Project story
A two-story Sunnyland home from the late 1970s still had its original single-pane aluminum-frame windows. Every one of them. Drafty in winter, condensation on the interior glass most mornings, and heating bills that reflected windows that were essentially open holes in the wall.
Total scope: 22 windows replaced with fiberglass triple-pane units. We measured every opening, ordered the full set (six weeks lead time), and installed over four working days. Every window got full-frame replacement — down to the rough opening, new flashing, and a proper sill pan.
Interior trim was upgraded to a wider, deeper craftsman-profile casing that better matched the era of the house. Exterior trim was replaced with PVC to eliminate the rot maintenance the original wood trim had required. The homeowners noticed the temperature and noise difference within a day. Their first winter heating bill after install was 28% lower than the previous year on comparable weather.
