EXCELLENT Based on 61 reviews Posted on Christian HayesTrustindex verifies that the original source of the review is Google. We’ve been lucky enough to partner with Cornerstone on two major home projects over the years: a complete kitchen remodel and the build out of a full in-law suite in our basement. You’d be hard pressed to find a better company to entrust with these projects. From design phase through to construction, Cornerstone holds their team accountable to the highest standard, and it shows. Everything from communication to finishing work are top notch. Finding a quality contractor can be such a gamble, but we can’t speak highly enough of this team.Posted on Jennifer WongTrustindex verifies that the original source of the review is Google. This team of dedicated professionals will complete your remodel project in no time. They are personable, reliable, and very communicative. They did a top notch job and we get so many compliments on our beautiful kitchen. We were able to login and see exactly what was going to be done and when and there were pictures provided in an online portfolio. They walked us through every step and we have a gorgeous kitchen remodel to show for it. Don't hesitate to call them today!Posted on Chris P.Trustindex verifies that the original source of the review is Google. The design-build team at Cornerstone did a remarkable job turning our closed-off kitchen into a welcoming, open space that adds brightness and appeal to the entire house. The team made the process seamless and stress-free. From cabinet and hardware selections in their studio, to project scheduling and the craftsmanship throughout the build - we appreciated the attention to detail and care for the customer.

WhelanTrustindex verifies that the original source of the review is Google. In 2024 we had Cornerstone update our basement to include an in-law suite and media room. They were a fantastic team to work with! The level of detail they put into their work and communication was excellent. A year later and our basement still looks brand new.Posted on Kathleen FowlerTrustindex verifies that the original source of the review is Google. We had Cornerstone build us a high top for 4 in our basement that faces our large screen TV! Love the opportunity to sit and chat and also the space to put apps for company! They did a great job….exactly what we asked for! Thanks Chris Mike and Molly!!Posted on Shawn HensonTrustindex verifies that the original source of the review is Google. We recently had our kitchen , dining room and living room area renovated by Cornerstone and everything looks amazing. They removed a wall between the narrow kitchen and dining room, opening up the space to look over a large kitchen island towards the living room and dining room space. The range was replaced with a wall oven and the island contains a cooktop. Note: 18 months ago Cornerstone raised the living room floor and built a foyer closet to replace the original closet the previous owners had removed. Pictures attached include the original kitchen, living room and dining room before the floor was raised and before the closet was added. The difference in livability, comfort and entertaining is profound. Thanks to the entire team at Cornerstone... special shout outs to Chris, Hannah, and Mike.Posted on Jonathan ResopTrustindex verifies that the original source of the review is Google. Cornerstone did an amazing job on our recent addition (new master bedroom + bathroom + walk-in closet + entire home re-siding + re-roofing) to our home! I can't recommend them enough! The entire team was amazing, particularly project manager Mike and design manager Hannah. The entire project, while huge, was smooth and seamless. Cornerstone was always professional and easy to work with. Thank you!!!Posted on Keisha JohnsonTrustindex verifies that the original source of the review is Google.
