We understand the diverse housing stock in Washington, from older Craftsman homes to more modern constructions. Our installation process is adapted to suit these different architectural styles and existing window frames. The steps involve careful removal of old units, thorough inspection and preparation of the rough opening, precise fitting of the new window, and secure sealing and finishing. The scope of the work, including the window's size, material, and any necessary modifications to the opening, will influence the project's overall duration.
