The Gorilla Works difference
Why homeowners pick Gorilla Works over the big national brands
Our own crew, start to finish
The people who measure your windows are the people who install them. No subcontractors and no handoffs.
Milgard quality, local pricing
Homeowners regularly tell us our bids came in well under Renewal by Andersen and DaBella for comparable windows.
A warranty that lasts
Qualifying installs carry a limited lifetime warranty, and we're licensed and insured in Oregon and Washington.
What our window customers say
“We had new vinyl windows installed by Gorilla Works. We needed 15 windows… 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!”
Gorilla Works replaced 18 windows for me and my wife and we couldn't be happier. Other bids from DaBella and Renewal by Andersen were 30–40% more for the same product. The team left our home cleaner than they found it.
As an older homeowner, the process was easy and stress-free. Kind, patient, knowledgeable team, smooth install, professional cleanup. Excellent value vs Renewal by Andersen and DaBella.
Really great job, very satisfied. Anton was very helpful. Would definitely recommend them for your window replacements.
Fantastic job replacing our windows — great communication and reasonable pricing, much more reasonable than RBA.
