Get New Custom Replacement Windows for Your Sterling, VA Home

The 2012 International Energy Conservation Code Energy Code set specific standards for the optimal performance of all products installed in residential structures. Replacement windows in Sterling, VA fall under these codes, and require low-E, or low emission glass in all replacement windows. Low-E glass is up to four times more efficient than previously available clear glass, and makes a dramatic difference in the energy efficiency and seasonal comfort of your home.

Replacement windows in Sterling, VA are designed for a variety of installation circumstances and techniques, and can raise your home's resale value and energy efficiency. In a full-frame installation, trim around the old window is removed and the old window frame is replaced. The replacement window is attached to the studs surrounding the window opening, and the trim is replaced.

Retrofit replacement windows are custom-made to match existing finished openings. Builders-grade windows are constructed in specific sizes, depending on the manufacturer, and wood windows come in standard sizes that dictate proper installation techniques. Custom-sized wood windows, the most expensive modern window products, are unusual.
