Cornerstone Home Improvements

We used Cornerstone for install of 15 new windows and we will be using them again for new entry and storm doors. I got multiple quotes for both windows and doors from competitors and Cornerstone’s pricing is by far the best on the market. The sales staff is not pushy at all and the installers were so helpful and definitely knew what they were doing. I would recommend them to anyone wanting to make quality improvements to their home that will last for years and years. The company takes great pride in the quality and value of their products and install.

The entire process of replacing 3 windows in our house was so smooth with Cornerstone. The salesman was extremely knowledgeable about the windows, and he was very helpful when discussing the available options and his recommendations. Once the windows arrived, the date of installation was scheduled quickly and it went very smoothly. We are very happy with the outcome. The employees are all extremely professional, and we’ve already set up a time to meet to discuss replacement of a few more windows!

Cornerstone did vinyl siding on our 1940s home. Their quote was in the mid-​to-​low price range, and they had more colors available than any of our other quotes.
The salesman Dennis answered my million questions and found me the color that I couldn’t find through any of the other companies. He was the opposite of pushy. I could tell that they were detail oriented and felt confident in their ability to make our house look great.
The installer James was the only one who touched the house (except for the gutters) so he took 100% of the responsibility for the insulation and siding. I loved that, because he was proud of his work. He was very detail oriented, and if I had a special request he found a way to make it happen. He was a former draftsman at an engineering firm too, so his ability to work around all of the old-​house– quirkiness was truly impressive. Very precise measurement and cutting. Great guy and very professional.
I would recommend Cornerstone with no reservations, and if you can, request James to do the install!

They did a good job on my windows and door installation. The team that installed were professional and kept me updated throughout the process. The only reason that it wasn’t 5 stars is that the door took a lot longer than planned so I had to have two separate installation days. Would use them again
