Home Improvement Review

Highly recommend Mainstream. We had an overall excellent experience with them. After some details were overlooked during the initial install, they stood by their word and came out promptly to make it right. Spencer, Marcy, and Tim are friendly, professional, and great to work with. We will be repeat customers and also recommend them to friends and family. Great company for home improvement projects!
