I was trying to figure out a way to meaningfully impact my curb appeal with a relatively small budget. I decided that a beautiful new entry door in hot burnt orange would be the transformative light remodel that I needed. The professionals at Cornerstone Home Improvements made the whole process painless and fun! Every detail, from selecting the modern style I wanted and acing the color match at the factory, to the installation process, was handled flawlessly by this family-owned and operated business.

Cornerstone is a great company to work with! Jessie was the guy who was assigned to do my windows and he was amazing. Jessie was very friendly and literally got the job done. In just a couple days I have received many compliments on my big picture window that he installed and I have to say I am so glad he was the one assigned to do my home. Thank you so much for beautifying my home, Jessie. Give Jessie three big hugs for being an AWESOME guy! Thanks, Cornerstone!

My neighbor had Cornerstone install some windows so I asked how she liked them. She recommended them and said they were good family company. I called and Dennis came out and gave a very good presentation of the windows they offer. We decided to order 11 windows, including a bay window, and 1 entry door. They sent out a guy to officially measure each window and door. A few weeks later, Brenda called to let me know the windows and door were ready to install.

When Brad and the crew came out they went right to work removing and putting in the new windows and door. Hard job but they knew exactly what needed to be done, cleaned up everything and even put back the window blinds. I very much appreciated they were able to get it done in one day. Windows and door look great! Very happy to recommend them.

We had an original picture window (41 yrs old) replaced with two double hung windows. The office staff is very friendly and kept us informed of the schedule to perform the work. Cornerstone did a very good job removing the old window and installing the new windows. The windows fit great and look great. They did the work in about two hrs and were very professional and considerate of our home during the installation.

We had received a couple of other quotes for this replacement work and Cornerstone was very competitive and I think the windows (ProVia) are very good energy rated windows. They had several selections of brick molding colors to choose from and one that matched our existing trim paint color. I would highly recommend Cornerstone for window replacement work.

Cornerstone did a fantastic job on my vinyl siding. The sales person, Don, was not pushy. The installers did a great job on install and clean up. The owner and office personnel were friendly and helpful when I called to ask questions. Cornerstone was not the highest or lowest quote I received when I compared companies but I chose them because a relative was happy with the siding they installed on her home. They also use a good quality siding (Royal Woodland) and offer a better warranty on their labor than the other companies I compared.

From start to finish the process was very quick and easy. Don was very pleasant to meet with at our in home consult. He was professional and had a great understanding of what we wanted. He did not pressure us to buy now or give us a deadline. After we decided to go with Cornerstone, they called us to let us know the windows were in and able to install them 3 days later. We had 10 windows to install and the crew had the old ones out and new windows placed within 5 hours. They worked efficiently and even fixed some wood rot that was found. My wife and I were extremely pleased with the Cornerstone team, and would highly recommend them to anyone needing windows.
