Testimonials

Dave Candland was great and communication was wonderful! My new windows look great and I couldn't be happier with them. I had bids from 2 other businesses and Mountain States was able to beat them both for price and quality. Overall very positive experience and would highly recommend.

I was having problems with my Hardie Board siding soaking up water and contacted Mountain States Windows and Siding. They were timely, professional, and helped us get our solution fixed. Great company and service.

We are doing a remodel on part of our home, which presents a need for some additional siding. Ian from Mountain State Windows & Siding went out of his way to help us get information on the siding we have. When we realized it may be hard to get, he went the extra mile to help us find a matching color in available products. Friendly, meaningful service!

Dave and the install crew were amazing from start to finish. We enjoyed the non-pushy sales pitches and the window quality was fantastic. They really made our windows pop! The crew was in constant communication and completed the job extremely quick.

Having served as a carrier pilot in the Navy where ‘attention to detail’ was paramount, it became evident that incorporating that thought process would serve one well in daily life and in future professional endeavors.That credo seems to be sadly lacking in many of today’s trade and construction businesses. That was certainly NOT the issue with Mountain States Windows which was researched and singled out to re-side my home. Upon close inspection of prior completed projects it became clear that this company would be able to retain the look and feel of the house that I personally built 35 years ago. The 2½ story Victorian style house with its intricate characteristics would certainly pose a challenge to any siding and window company but Mountain States was confident in their expertise and guaranteed my complete satisfaction and at a price that was exceptionally reasonable compared to other competitive bids. And the quoted price was exactly the final price paid with no ‘add-on surprise’ expenses for oversights or unforseen problems. Truly a professional operation with the precise outcome I wanted. I would highly recommend this business to anyone who needs siding, windows, or doors.
