Replacement Windows in Lake Oswego, OR
Lake Oswego's housing skews upscale and established — mid-century moderns near the Lake, 1980s-through-2000s custom homes in First Addition and along Lakeview Boulevard, and a steady share of waterfront properties with their own window-replacement priorities.
From Oswego Lake to the First Addition, we help homeowners match premium windows — Milgard, Simonton, and Marvin — to homes that deserve them, and install them to last.
Lake Oswego homeowners work with the same Portland team — employee installers, one showroom, one standard. We also serve nearby West Linn and Tualatin.
A team that gets it right.
We don't send strangers to your house. Our window and door installers work for us — the same trained team, year after year. They know the work. They know our standards. And they have a name attached to every job.
Lifetime Windows & Doors has been in the Pacific Northwest since 1998. Same ownership. Same commitment. We're not a franchise. We're not going anywhere.
Not recently. Not after a cleanup. Since 1998. That's what happens when you do the work right and stand behind it.
Windows. Doors. Siding. Done right.
We help Lake Oswego homeowners make the right call on replacement windows, doors, and siding. Here's what that looks like.
Replacement Windows
Your windows should keep your home comfortable and your energy bills low. We carry Milgard, Simonton, and Marvin — premium brands installed by our own employee team. Not subcontractors. The install is what makes the difference, and ours is done right.

Siding
Windows and siding work together. Sometimes the only right way to install new windows is alongside new siding — and doing it any other way leaves the job half-finished. That's why we offer siding. We manage the project, select the materials, and ensure quality. Installation is handled by our trusted partner contractors who work exclusively with our locations.

How much does window replacement cost in Lake Oswego, OR?
The cost depends on your home, the number of windows, the style, and the brand you choose. Premium and wood-look lines run higher. We'll walk you through your options and provide a proposal tailored to your project. Lake Oswego homeowners get a free in-home estimate, so you have an exact price for your home — no guessing.
How long does it take to replace windows in my home?
Most installs run 30–60 minutes per window, and a full-home project is typically 2–4 days. We schedule the timing around your home, not the other way around.
Do you use subcontractors for window installation in Lake Oswego?
No. Our window and door installers are our employees — not subcontractors. The same trained team, year after year. That's one of the biggest things that sets us apart.
How much will I save on my energy bills with new windows?
Pacific Northwest homeowners typically see 12–25% lower heating and cooling costs with high-performance windows. Your exact savings depend on your current windows, your home's size, and the package you choose.
