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. Good work Dorian. MARY

Over the years, I have had many window projects: replacement windows, new construction windows,french doors, and the latest, Milgard Essence Windows, wood replacement windows for my newly renovated home. Dorian has deliver excellent service and the best prices in the Portland Metro. I am 100% confident that Therm-o-loc is the only call you need to make.

Over more than 10 years I have called around for bids and every time decided on Therm-o-lock window company because Dorian has simply represented the best in the industry.

Dorian and his crew did an excellent job installing our new Milgard sliding glass door. Their workmanship was superior and fast. The end result is that we are very happy with our new door. Great work guys!

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. Thanks again Dorian. Bob & Liz

This started with a knock on the door. I had been interested in replacing my single pane wood windows. Half were painted shut, the other half had broken rope and weights. I got 3 estimates this way, but Dorian came dressed casual, with a great deal. He came with a crew and they did my house in 3 hours. Problem was, the new windows made my poor siding look really bad, so I contracted him and his crew to install hardy plank type siding and paint. I added new gutters and a new garage door and my house was completely transformed. I still have to check the address when I pull up, it was that big of an improvement. My neighbors are all astounded. I wish I could post before and after photos. Dorian is a great guy, and his crew is friendly and top notch. BTW....hasn't been all that cold yet, but the furnace hardly runs and the house is very quiet. Glad we chose Milgard. Still waiting for the rebate. Highly recommended. Ron

We are extremely happy with our new Milgard windows, and Dorian's attention to detail in making sure the completed job met our expectations. Dorian's price was the best we found, and he promised to be on the job, himself, to supervise the work. It was a pleasure to work with Dorian and his crew. We recommend Therm-O-Loc to anyone who wants top quality workmanship and an excellent product.
