Single-pane and early double-pane windows lose 25-30% of the energy in your house. You pay to heat or cool air that’s escaping through the glass and frame. In the DMV — humid summers, cold winters — the bleed is constant.
Drafty windows also let outside noise in, fail to filter UV (your furniture and floors fade), and look tired against an otherwise updated house.
Modern windows are a different product. Low-E coatings, argon fills, fiberglass and composite frames, modern weatherstripping. The right windows, installed right, pay for themselves in energy savings AND make your house feel different to live in.
We install only what we'd put in our own homes. Here's what each option is best at.

Every window is built to your opening. Lead time is typically 4-8 weeks. We schedule the install once delivery is confirmed.
Most whole-house jobs finish in 1-2 days. We protect floors and furniture, work room-by-room, and clean as we go.

Installed cost in the DMV runs $500-$2,400 per window depending on size, material, and brand. Vinyl windows fall on the lower end; wood-clad windows (Andersen, Marvin) on the higher end. Whole-house projects typically save 10-15% over individual windows.
Most whole-house projects finish in 1-2 days of install time. Lead time on custom-built windows is 4-8 weeks from order to delivery.
Depends on install method. We mostly use insert (pocket) installation when the existing frame is sound — fastest, least disruption. Full-frame replacement is needed if the existing frame has rot or for major frame upgrades. We assess at the quote.
Vinyl: lower cost, no painting needed, lifetime warranty, but limited custom sizes. Wood-clad (Andersen, Pella, Marvin): more expensive but premium aesthetic, broader custom options, and higher resale impact. Both perform similarly on energy efficiency now.
Replacing single-pane or 1990s double-pane windows with modern Low-E argon-filled windows typically reduces heating/cooling bills 15-25%. The Department of Energy estimates an average DMV home saves $250-$450/year on energy.
