EXCELLENT Based on 67 reviews Posted on Maritza Saint VilTrustindex verifies that the original source of the review is Google. We have wanted to remodel our kitchen for years but were apprehensive about the disruption to our lives and the ubiquitous contractor horror stories. From our very first meetings, the team put us at ease with their level of expertise and organization. Hannah and Chris listened to our desires and concerns. They and their team created a comprehensive plan for our renovation. Once the work actually began, the team continued to be extremely organized and communicative. Any issues that arose were immediately handled and we could not be more thrilled with the result. Major thank you to Hannah, Chris, Kevin, Mason, and the countless others that made helped us obtain our fabulous kitchen!Posted on ChaunceyTrustindex verifies that the original source of the review is Google. Another well known construction company in Severna Park didn’t put a wax seal on our toilet when they did the floors in the bathroom. Needless to say, a slow leak occurred over time, creating mold. PE came in, cleaned up, and made a proper installation to help out our mind at ease.Posted on JULIE OTrustindex verifies that the original source of the review is Google. If you want a professional, talented, skillful organization with integrity, we strongly recommend CONERSTONE REMODELING. We started with Chris and Annamarie, the project developer and designer both with excellent skills in the suggestions of what we could do and the proposed and completed design. Kevin was our project manager. Our entire kitchen and dining room were gutted, ceiling and walls removed etc. We can't imagine a better relationship between homeowners and the project manager. For eight weeks, daily, Kevin kept us completely informed of the upcoming assignments, the tradesmen responsibilities and results expected and answered any questions or concerns we had with clarity and an appreciated demeaner. All major remodels come with some disappointments, communication errors etc. - but not with us and Kevin. Working along with Kevin was Mason. Again we were totally impressed with his skills and determination to complete his tasks impeccably and with a great personality. We don't think we could have had a better carpenter on board then Mason. We are totally content and grateful for the end result on a remodel that transformed our home. The complete organization from the office, the tradesmen to the onsite job workforce exceeded our expectations and we could not give any thing less then an A+ rating. Job well done. Julie and Bill O'H.Posted on Dave GeeTrustindex verifies that the original source of the review is Google. We spoke with several design and build firms before being referred to Cornerstone by a company in the Hunt Valley area—and we’re so glad we found them. What first impressed us was their thoughtful design work, but it was their production team that truly stood out. They managed the project seamlessly, kept us updated every day, and addressed any issues quickly and professionally. Cornerstone remodeled our master bath, kitchen, powder room, and both our front and back stair railings, and we couldn’t be happier with the results.Posted on Abe LazarTrustindex verifies that the original source of the review is Google. Although I did not end up going through with the project (We ended up deciding to sell our home), I do want to say how blown away I was by the entire process. I've already received multiple bids for the addition by other reputable contractors but I was not very impressed by any of them. They seemed rush, didn't measure accurately and left me with more questions than answers. Cornerstone was such a difference! The initial call was similar in that they get all the details about the project but Kara was definitely much more approachable on the phone and answered a lot more of my questions. The real magic started when they arrived for the consultation. A team of 4 or 5 people arrived swooped in to go over every aspect of the project. I felt they really understood what I was trying to accomplish. They took the time to listen, measure and give their suggestions and ideas. I've never experienced anything like this before and it left me feeling like these people really knew and understood the full scope of the project. It made me feel that the other contractors were simply underbidding in order to put in a future change order to hike up the cost down the line as they didn't ask half the questions that Cornerstone did. Cornerstone didn't miss a thing during their assessment and it was very impressive. Having been in the service industry for over 20 years, I can say that Cornerstone really is above and beyond the rest. They truly understand customer service.Posted on JainineTrustindex verifies that the original source of the review is Google. Cornerstone’s design build team was exactly what we were looking for when deciding to remodel our first floor. They were amazing to work with and we can’t recommend them enough. They literally took care of everything and made the process super easy for us. They hold themselves to a very high standard and you can tell in their designs and workmanship. Thank you to the entire Cornerstone team and a special thanks to Chris, Hannah and Phil for turning our kitchen and first floor into a beautiful home we can be proud of. We absolutely love it!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.
