Angie’s List

“Cornerstone made it simple and easy to get all of our windows replaced. They had a full crew, arrived on time, spread protective covers over everything, and handled the entire window replacement process (including sliders and screens) in a quick and professional manner. We had investigated several other firms and took the recommendations of our complex’s maintenance manager and went with Cornerstone. Based on results, it was one of the best recommendations we have ever received for any kind of home maintenance, upgrade and repair work.”  -Angieslist.com, Mike R. of Rancho Palos Verdes

“From our initial visit in the showroom to the consultation and measuring in our home and then the installation, the products, staff, professionalism and the experience was outstanding.” – Angieslist.com,  Ed B.  of Rancho Palos Verdes

“Excellent!!! extremely pleased with installation of 17 windows. The crew were friendly and very clean. I will be sure to have referals, and my business again” –  Angieslist.com, Diamond S. of Los Angeles.

“I am writing this review because I broke the handle on my sliding door today and went to their shop to inquire about a replacement. They immediately brought me the replacement handle and off I went. No hassles. Cornerstone was awesome when they did the install several years ago. Punctual. Professional. No surprises. My two experiences with Cornerstone have been great and I would recommend them to anyone looking to replace windows or doors. ” -Angieslist.com, Sandra M. of Redondo Beach
