Window Replacement Built for Hillsboro Homes

Hillsboro sits at the heart of the Silicon Forest, and its housing runs the full range. Older homes near downtown still carry original single-pane windows, and the wave of 1990s to 2010s subdivisions in Orenco Station, Tanasbourne and AmberGlen is now reaching the age where builder-grade windows fog between the panes and leak heat. Replacing them fixes the draft and the energy bill in one trip. Here is what we hold to on every Hillsboro job.

  • Oregon energy code. New and replacement windows in Oregon have to reach a U-factor of 0.30 or lower. We order every Milgard window with the Low-E glass and gas fill that meets it, so your job passes inspection.
  • Egress where it counts. Bedroom windows have to open wide enough for an emergency escape under Oregon code. If your old openings fall short, we tell you before we order, not after.
  • Safety glazing. Windows next to a door, low to the floor, or beside a tub or stairs need tempered glass. We spec it wherever the code calls for it.
  • Permit and inspection. We pull whatever permit your project needs through the City of Hillsboro and meet the inspector, so none of that lands on you.

We replace windows throughout Hillsboro and the neighborhoods around it, from Orenco Station, Tanasbourne and AmberGlen to Jackson School, Reedville, Witch Hazel and Brookwood, plus nearby Aloha, Cornelius and North Plains.

FAQ

Frequently Asked Questions

Have questions about materials, pricing, or installation? Here are the answers homeowners ask us most.

Do I need a permit to replace windows in Hillsboro?-
Often, yes. A full window replacement in Oregon can require a building permit, especially when an opening changes or a bedroom egress window is involved. We check what your Hillsboro job needs, pull any permit through the City of Hillsboro, and meet the inspector so it is signed off correctly.
What window efficiency does Oregon require?+
Oregon code requires new and replacement windows to reach a U-factor of 0.30 or lower. We order Milgard windows with the Low-E glass and gas fill that meets it, so your Hillsboro project passes inspection.
What windows do you install in Hillsboro?+
Milgard vinyl and fiberglass windows, in the styles most Hillsboro homes use: double-hung, casement, slider, picture and bay or bow. We install vinyl and fiberglass, not wood-frame windows.
Do you serve the areas around Hillsboro?+
Yes. We cover Hillsboro and the surrounding Washington County communities, including Aloha, Cornelius and North Plains, and neighborhoods like Orenco Station, Tanasbourne, AmberGlen and Witch Hazel.
