Ann Goulet

We highly recommend McDowell Mountain Builders to get the job done right! They are trustworthy and reliable. They transformed our out dated step up/ step down cave-like snail shaped master shower into a beautiful open and well functioning shower. Son Steve Diltz was awesome to work with! He guided us thru this process with great communication via texts, , phone calls and frequent on site visits to monitor work. From planning, to demo, plumbing, electrical, tile, drywall, paint, glass enclosure everyone was professional and courteous. Looking forward to updating other bathrooms in our home!

Jonathan Philipson

We hired McDowell Mountain Builders to build an entertainment wall in our home that we purchased earlier this year. The project included building the center part of the wall out 14 inches and adding tile and shelving as seen in the attached pictures. MMB, led by Steve Diltz, did a superb job in this construction project. The worker who did most of the work was one of the most careful and skilled carpenters I have ever seen. We are so pleased with the final product that we are considering hiring MMB to build an addition on the house ( if the HOA approves it).
