Window replacement involves removing existing windows and installing new, energy-efficient window systems that improve insulation, reduce air leakage, and enhance overall comfort. Depending on your home’s condition and project scope, window replacement can be completed using retrofit windows or new construction windows.
Proper installation is critical to ensure weather resistance, energy efficiency, and long-term performance—especially in foggy and moisture-prone environments.

Retrofit windows are installed within the existing window frame and are ideal when the surrounding framing and stucco or siding are in good condition.
