Headquartered in Portland Oregon, Therm-O-Loc serves the entire Portland Metro area as well as southwest Washington. We are a family owned business. Having resided in the Portland area for over 40 years, we love servicing the place that we call home. The Portland/Vancouver community is very important to us, and we are grateful to have the opportunity to provide exceptional service to those who live here.
Some of the areas that we serve include:
We are quite pleased with the Milgard windows that Dorian and his crew installed as replacements to our old wooden cased windows. We had 20 windows to replace and Dorian and his crew got the job done in one day!! Therm-O-loc was the lowest bid we received and we are very pleased with the end results. We would be pleased to recommend Dorian's company to anyone who would like to know how happy we are.
I have done business with Dorian at Therm-O-Loc for 15 years. He really delivers, consistent, on-time and an all round good guy. I was so happy to have him tear out a terrible window and install one that works for me. He never disappoints.
We are very happy with our 14 new Milgard replacement windows. The price, quality of installation, product, cleanliness, consideration of our animals, general demeanor, and thoughtfulness of you and your crew were excellent. We would be happy to recommend you anytime, and hope you can do some other projects for us in the future.
