The Job

What "Window Installation" Covers

Window installation is the broader job: setting a window into a brand-new or framed-out opening โ€” think additions, new construction, or a remodel where the opening itself is changing size or location. That's different from swapping an existing window in its current opening (see our window replacement page if that's your project).

Getting a new installation right means correct flashing and weatherproofing from the studs out, level and square setting so the window operates smoothly for years, and proper insulation and air sealing around the frame. Skipping any of that is how homeowners end up with leaks and drafts two winters later.

New InstallationNew or resized opening โ€” additions, remodels, new construction. Full frame-out and weatherproofing from scratch.
ReplacementExisting opening, old window comes out, new insert window goes in. No siding or drywall disruption.
