Window Replacement Built for Oregon City Homes

Oregon City is one of the oldest towns in the state, and its housing shows it. The historic neighborhoods around McLoughlin and downtown carry early-1900s homes with original wood or single-pane windows that stick, rattle and leak heat, and on an older home the fix has to respect the way the house was built. Up on the hilltop and out toward Caufield, Holcomb and Beavercreek, the newer subdivisions are now hitting the age where builder-grade windows start to fog and drain heat. New Milgard windows bring the comfort and the energy bill up to date in one trip. Here is what we hold to on every Oregon City 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 Oregon City and meet the inspector, so none of that lands on you.

We replace windows throughout Oregon City and the neighborhoods around it, from McLoughlin and the historic downtown to Hilltop, Caufield, Rose Highlands, Park Place, Barclay Hills and the South End, plus nearby West Linn, Gladstone, Beavercreek and Canby.

We couldn’t be happier with our experience with Gorilla works! The sales guy was awesome-professional, friendly, and great to work with from start to finish. The installers were just as great! They were very friendly, respectful of our home, and did an excellent job installing our new windows. Overall, we are very happy with our new windows and the entire experience. Everyone we dealt with was friendly and professional, and I’m happy to recommend Gorilla Works to anyone looking for new windows.

Gorilla Works did an amazing job with my new privacy fence. It turned out even better than I hoped for. Because the fence is so beautiful, I’m going to need to quit neglecting my yard and bring it up the beauty and quality of the fence. Highly recommend them. Pricing was really good, and they were very even able to start and get done in a shorter timeframe than anticipated.

We had new vinyl windows installed about 4-5 wks ago by Gorilla Works. We needed 15 windows. We thought 15 windows were ordered and getting installed. Installation day came. 14 windows were installed and paid for. We still need a 15th window. After some confusion, some miscommunication. And a call from the owner. We are getting our 15th window!! Yay! You will be glad you went with Gorilla Works!! David, Anton, Isaac, Eric, and Alvin you guys are all exceptional! They will go above and beyond to make sure you have a 5 star experience! You deserve 100 stars!
