Window Replacementin Lake Oswego

Windows and doors for Lake Oswego homes.

Lake Oswego homes sit under big firs, on hillsides, and along the water, and a lot of them were built for the view. Getting that view back, without the drafts and the fogged glass, is most of what we do here.

What matters for a window job here.

Two thirds of Lake Oswego homes went up between 1960 and 1999, split almost evenly between the two eras. The older half often still has aluminum or early wood windows. The newer half is now 25 to 45 years old, which is about when dual-pane seals give out and glass starts to fog.

    Built before 1980

    Paint from before 1978 can contain lead, and window work disturbs it. Oregon requires a Lead-Based Paint Renovation license and lead-safe practices for that work. Ask any installer to show you theirs.

Questions fromLake Oswego.

Straight answers.

Do I need a permit to replace windows in Lake Oswego?
Usually not. Oregon's residential code exempts door and window replacement from permits unless a structural member changes, like making an opening bigger, or the opening has to be fire rated. The new windows still have to meet the energy code. If your home is a designated historic landmark, the city may review exterior changes. We check before we quote.
Is lead paint a concern in Lake Oswego homes?
It can be. 46% of Lake Oswego homes were built before 1980, and paint from before 1978 can contain lead. Window work disturbs painted surfaces, so in Oregon a contractor working on a pre-1978 home must hold a Lead-Based Paint Renovation license from the Construction Contractors Board and follow lead-safe practices. Ask any installer to show you theirs.
Are there rebates for new windows in Lake Oswego?
Not many right now. Energy Trust of Oregon discontinued its window incentive for Oregon homes on January 1, 2026, and the federal 25C tax credit does not cover windows installed after 2025. If anyone quotes you a rebate, ask to see it in writing. If your power comes from a city-owned or co-op utility, ask them directly.
Do you charge to come out to Lake Oswego?
No. The consultation is free, in your home, on your schedule. We look at every window and door, measure, walk you through the options, and leave you with a written, itemized quote.
