EXCELLENT Based on 57 reviews M. Whelan2025-06-13Trustindex 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. Kathleen Fowler2025-06-09Trustindex 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!! Shawn Henson2025-05-02Trustindex 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.

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!!! Keisha Johnson2024-11-21Trustindex verifies that the original source of the review is Google. Our renovation experience with Cornerstone Remodeling was both creative and collaborative. Hannah and Heath worked closely with us to achieve every goal that we had and shared ideas that we had not considered previously. Our end result is better than we imagined!

Finding a Contractor and team that have a good work ethic, are organized, trustworthy, and can do a great job on your home renovation is hard to come by. We were able to find all of those qualities and more in the team at Cornerstone Remodeling. My husband and I hired them to help us design and renovate our forever home. Their work has been impeccable and the experience has been wonderful. Going through a 3-story extension of our home was very stressful and the team at Cornerstone made us feel supported, helped us to make difficult decisions, and of course in the end delivered a beautiful product; a spacious upscale kitchen makeover, a luxurious master bath ensuite and an extended basement area that now includes a full walkout. Everyone was extremely professional and the crews worked diligently to ensure the project stayed on schedule to meet our completion date. If you are researching design/build contractors for your next project, then look no further, as we are very satisfied repeat customers. Shawn Henson2024-09-10Trustindex verifies that the original source of the review is Google. Cornerstone has completed several major projects for us; raising the floor of our sunken living room, installing a hall closet that had been removed, removing a 45 yr old screen porch and replacing it with Trex decking, remodeling our family room to remove a wood burning fireplace, install a wall of beautiful windows and sliding door and install an electric fireplace insert. All electrical, drywall and painting was also completed by Cornerstone. Our house is completely transformed. We are very excited for the kitchen remodel in January. Lillian Miller2024-09-05Trustindex verifies that the original source of the review is Google. Cornerstone remodeled our kitchen and a bathroom and also put in new hardwood floors and new lights. Everything looks great and work’s well. We are loving all of it. The people at Cornerstone are very nice, easy to work with and do a great job.

Full Basement Remodel
Remodeling a basement can add livable space and value to a home. Basements are also multifunctional, and provide room for entertaining, relaxing, and family time. Often, remodeling an entire basement can entail a large investment, and Cornerstone offers options to finish the space in phases.
Throughout the process, clients work closely with an in-house designer to ensure project alignment, and the basement renovation goals are met in cohesive and beautiful ways!




Basement With Kitchenette
The addition of a kitchenette or bar is a great way to add another level of entertaining space to a home. In this type of basement renovation, a variety of details can be applied in customized ways. For some, it may include the simple addition of a sink and small refrigerator, and for others, it may encompass the creation of a full bar with wine storage, seating for guests, and additional appliances.
Clients work with an in-house designer to build a space that will be a showstopper – no matter how they’re using it!



Basement With Bed & Bath
Adding a bedroom and bathroom to a basement can increase the value of a home. While many clients desire these spaces for guest use, often they’re needed for relatives or family members for extended periods of time. These spaces can also be used for theatre rooms, dedicated playrooms, or home offices.
No matter the goals, clients work closely with an in-house designer to create areas that are functional and stylish!
