Clear Results That Make Your Replacements Worth It
Persistent drafts and moisture damage made exterior upgrades unavoidable for this two-story home. A full window and front door replacement was planned after our team identified energy loss areas and worn-out sill sections during inspection. The solution included installing double-glazed low-e windows in the main living spaces and fitting a reinforced fiberglass front door with a composite threshold to improve durability and moisture protection.
The work included selective framing repairs, full flashing replacement and new exterior trim to match existing styling. Over ten days, installers completed the project with staged room access to limit homeowner disruption. Post-installation blower door testing confirmed significant air-seal improvements and energy modeling projected lower heating and cooling costs.
The homeowner reported immediate comfort gains and praised the precise fit and quiet operation of new units. Final inspection passed without issues and we provided a documented maintenance schedule and warranties for both glass and labor.
