Don't just take our word for it...

Joe H.

I am very pleased with Frey Construction. They replaced my roof and gutters. The workers were fast and efficient, and they were always courteous and professional. The office staff was patient and helpful and I appreciated all the time they spent to answer my questions. The quality of work is exceptional and they exceeded my expectations with the clean up afterwards. I highly recommend them!

Brenda A.

Frey has done a lot of work for us and the quality is always great. My favorite thing about them is that they are extremely responsive and professional with great customer service. We've previously worked with them on siding and gutters. Most recently I had some windows replaced. They were very helpful and assisted in removing a wall-mounted shelf, which I consider an above and beyond service.
