Very thorough,responsive and competitively priced dealer. I had many concerns and questions regarding window replacements for my small ninety year old Oakland bungalow. The folks at Quality Construction Supply, especially Law, thoroughly addressed those concerns. Over the course of several visits Law patiently answered questions and explained options. He also replied promptly to emails and then kept me informed as to the status of my order. The vinyl Milgard windows I finally chose were very competitively priced and are a big improvement in appearance and function over the windows they replaced. June 27, 2014
The dealer was incrediably responsive and professional After having experienced frustration with the difficulty in contacting contractors and other dealers, it was a real pleasure to work with Law and the rest of the staff at Quality Construction. Phones calls returned very quickly, patience in answering our many questions, and then revising multiple quotes as we worked through the process. When all said and done, we are very happy with the end result and look forward to working with Quality Construction again in the future, thanks so much ! April 16, 2014

Stress free experience, highly recommended Quality Construction Supply (QCS) made our shopping experience painless and stress free. Not knowing much about one brand vs the other, they were able to answer all of our questions and allow us to make an informed decision on what to use. Ultimately we chose Milgard and we couldn't be happier with the experience and the results! March 1, 2014
