    Cornerstone Foundations did an outstanding job installing helical piers to reinforce our houses foundation in Gibsonville. From the initial consultation to the completion of the project, their team was professional, knowledgeable, and highly efficient. They thoroughly explained the process, answered all our questions, and provided a fair estimate.The installation was completed on schedule, and the crew was respectful of our property, ensuring everything was cleaned up afterward. The quality of their work has given us peace of mind, knowing our home is now secure and stable. We highly recommend Cornerstone Foundations for anyone needing foundation repair. Their expertise and dedication to customer satisfaction are truly commendable!

    Cornerstone is the only company we trust with our foundation. Last year, we had them install helical piers for the side of the house that was sinking. After getting many quotes, they offered the most effective solution for a fair price without being salesman pushy. We were so pleased with the work they did, we called them recently for a dip in the floor. They installed a new girder and dehumidifier and solved the problem. The crew was courteous and did a wonderful job. I’d recommend them to anyone. Thanks, guys!

    Thanks Jon and team! Cornerstone did a great job with our foundation repair based off a structural engineering report. Handled and responded ahead of schedule every step of the way, knowing we were trying to put our house on the market. Again, great job guys.

    Cornerstone handled the repair of a foundation as well as the installation of a dehumidifier at a rental property. They handled it with great care, attention, and the communication throughout was excellent. Would highly recommend Cornerstone and appreciate their help on this project.

    Jonathans crew did an outstanding job, and his foreman, Rafael, was equally impressive. The team was easy to coordinate with, completing the installation of the helical piers quickly and efficiently. Their pricing was competitive and reasonable.

    Honest and informative inspection. They came out for free, inspected my concerns, and did not find any major issues. They did not try to sell me any work I didnt need (other companies may have tried to coerce me into services I didnt need).If I do have any major issues down the road, theyll be the first company I call.

    Cornerstone did an amazing job on my small framed home. Ill never forget watching two men hang dig down to my foundation. It was 90+ degrees that day too. Excellent work. Im very satisfied. Its also affordable.

    My family had an excellent experience with Cornerstone Foundation Repair. Before working with them, we received a structural engineering report that called for extensive repairs and sent it to Cornerstone and other foundation companies for a quote. Jonathan was responsive in putting together the quote and came out to our home to confirm details so that his figures would be accurate. He also talked us through opportunities to be more conservative with the work to still get the desired result and he offered to talk to our engineer to confirm the plans. Based on this and the reasonable price, we felt confident moving forward with Cornerstone. Jonathan continued to be very responsive to our questions when we were finalizing the quote, signing the contract, and starting the work. When his crew came to our home to start the excavation and repairs, they were considerate of our property and left the site very clean each day. The work is high quality and carries a lifetime warranty.

    We had some pretty bad wood rot in our crawlspace. Jonathan, of Cornerstone, did a great job of following the engineers requirements in fixing the problems. The extensive work was done on time and at less cost than quoted. I would recommend Cornerstone for any foundation work you might need.

  • Review 10 (2024-03-19 - Rating: 5)

    Fair pricing. Excellent work. The crew worked tirelessly and efficiently. My home feels more solid now than when iI purchased it almost 31 years ago. I am so grateful. And the transferrable warranty definitely brings peace of mind. Every single team member was in sync with with each other and super-professional. The concrete masonry units are beautifully built and aligned. Just lovely. We walked the interior floors to check for level and bounce and crew followed through. The crew also completed the vapor barrier work with care and cleaned up impeccably after the job was completed.Thank you so so much!I highly recommend this company! Also, to make it easier for them I used the Stonewall Engineering for a structural engineering report. This information makes a job much easier and more accurate to quote.My homes foundation is now is now better than new.

    Reached out to John to get a second opinion about possible structural issues. Diagnosed them, looked at previous work done, and answered all of my questions without charging me a dime. He found some potential work he could do on my house and when I asked him for a quote, he told me I should prioritize the other structural things first. Would recommend and use again (preferably paying him the next time)!!

  • Review 12 (2023-09-08 - Rating: 5)

    Highly recommend! We were given a $45K estimate from another big name in foundation repair. Due to that company’s strong arm sales tactics, I was uncomfortable with proceeding with them and wanted a second opinion. We called Jon out. He took his time to look at our front porch and foundation. He easily could have sold us on repairs after we’d already been prepared we needed “major work” from the other guys. Instead, he was honest and told me what he saw wasn’t a big deal. He made some simple recommendations for some caulk work we could do ourselves. We have some other foundation work that needs to be done and it’s a no- brainer that we will use Cornerstone. I was highly impressed with Jon and extremely appreciative of his honesty.

  • Review 13 (2023-08-02 - Rating: 5)

    Although I did not use Cornerstone for any work, I want to leave my feedback. They came out and address concerns I had with my house. They said it was nothing to be concerned about it, and didnt try to upsell me. Further, they even recommended that I use a different company with smaller equipment for a concrete job and verified how to do the slab. Working with them felt honest. There were no pushy sales tactics. I would not hesitate to give them a call if you have foundation concerns. From my experience, they were professional and honest.

    I bought a 1960s single-family home that had structural issues, and received a copy of the sellers structural engineering report at closing. I sent this report to 4-5 contractors to quote out the work, and ended up choosing Jonathan due to his cost and customer service. The quotes came back from $7,200 - 11,500, and Jonathan was the $7,200. There were 2 others competitive with Jonathan, but I liked his demeanor and customer service better so chose him.The repairs were scheduled around 3-4 weeks out, and I got a call the day of asking if we could push right 1 week due to rain the day prior and day of.The repairs took about 1.5 days, and the crew was super sensitive about COVID, by both minimizing coming in the house, and wearing masks when they did. The yard looked as good as it could after the work, and Im confident in the work, since it comes with a lifetime transferrable warranty.Jonathan was quick on the initial estimate, and tolerable on follow-on paperwork. I view it as a small sacrifice to have to follow-up a bit to get such a competitive price on a project. I also dont really trust contractors that are good at paperwork.

  • Review 15 (2019-01-17 - Rating: 5)

    So I never meet Jonathan in person(due to my job) but he answers his phone quick and returns calls same day. Had cornerstone an a big national brand come out for quotes an Jonathan beat there’s by a third ( and did more work than the others would even quote me for)! Cornerstone will be the only people o recommend for foundation work. oh an my 2yo enjoyed watching the crew with the backhoe dig up an bury the gutters they even waved back to him. Great crew all around.

  • Review 16 (2020-01-27 - Rating: 5)

    Perfect example of a well run local business. I’m very satisfied with the work completed and would 100% recommend this company to others in the area.We had a Structural Engineer come out and evaluate our foundation problems. They wrote us a detailed report of what actions we needed to take. We gave this report to Cornerstone and their team executed the work exactly as the Structural Engineer had recommended. Jonathon and his crew were very friendly and took the time to answer all of our questions. It could not have been a better experience. Thank you everyone at Cornerstone!

  • Review 17 (2018-06-04 - Rating: 5)

    Jonathan was very professional with a written estimate proposal of exactly what services I needed to correct water problem and cracks over doors. All the work was performed as stated on proposal and no hidden or cost overruns at completion. Great job by Jonathan and his crew. As a side note had 2 other established companies propose bids that were much higher for the same job and not very professional. Always wary of any company that states wow you got some serious problems underneath your house and provides a ball park estimate of twice the amount of Cornerstone.

  • Review 18 (2019-05-03 - Rating: 5)

    Jonathan and his crew were awesome. Jonathan responded quickly to all my inquiries and his crew worked so hard and were very polite. Miguel was a great crew leader and they left everything so neat and clean when they were finished. I highly recommend Cornerstone for any foundation repair or waterproofing services.

  • Review 19 (2023-03-27 - Rating: 5)

    I was referred to John after calling several companies who said that they couldnt help me. We had a concrete slab poured for an Endless Pool and it began to settle on one diagonal corner. The pool was not level and I had no idea if this would continue to shift. John came out and analyzed the situation and within 72 hours had a crew out to stabilize the pad with a pier system. We were told that we probably couldnt raise the pad but Johns crew was able to raise it some. Grateful for his expertise, professionalism and rapid response. Highest personal recommendation for John and his team.

    Thomas and the whole crew at Cornerstone did an excellent job with the waterproofing of our crawlspace and repair of several joists and piers in the foundation. The price was competitive, communication clear, everyone was on time and the job was thorough and correct. Would highly recommend!

  • Review 21 (2018-12-06 - Rating: 5)

    I just had a visit from Jonathan at Cornerstone—a free consultation—and he assured me that we didnt need the services of his firm. He was knowledgeable (he described what he would want to see in the crawl space, and confirmed his assumptions when we went into the space), thoughtful (he elicited from me what changes to the drainage around the house might have changed conditions in the crawlspace, and led therefore to the conditions we are seeing in the house), and helpful (he suggested a course of action that wouldnt earn him a dime). I would recommend his company highly to anyone looking for assistance with foundation issues.

  • Review 22 (2017-12-08 - Rating: 5)

    Highest marks for Jon and his crew! We had a 1/2 drop at one corner of our home (back-filled slab foundation), and that might not seem like a big deal compared to some repairs, but it was only going to get worse. We had 3 estimates, two of which came from high-profile companies that you might see on TV. They WAY oversold us on what needed to be done, and those repair estimates were incredibly expensive. When Jon came out, he was considerate of my time and he assessed the issues in a professional way. In fact, he pointed out things that the other people had missed because he owns the company and is not a sales rep. His estimate of the repair and the price was fair. The work was done four days ago and we are thoroughly pleased. My closet door closes now. His crew was pleasant to deal with, very tolerant (and indulgent) of my curiosity, and they stayed on-task. No one wants to go through this, but if they do, the best thing they can do is go through it with Cornerstone.Sonja BeachJamestown, NC

    Props to Cornerstone Foundation Repair!! They have done well BEYOND great service! They are very professional, informational, and affordable. With all of the work they had to do (drainage, hellical piles, lifting the home) they took the time and repaired the yard to where it looked even better than it did before. We already see improvements on the leveling of the house. Would recommend Cornerstone to anybody. 5 stars completely.

  • Review 24 (2017-10-27 - Rating: 5)

    I worked closely with John over the last few months. He is a true professional that conducts himself how I wish everyone in the industry would - he was honest, great at communicating and got his work done right on time.The cherry on top is that John seems to know everyone in the community and has connections for almost any type of repair or job. These are good people!!! :)

  • Review 25 (2018-06-09 - Rating: 5)

    Incredibly professional, responsive, and with a high attention to detail. The team has a very quick turnaround. I was very worried about the work we needed to do but Jonathan and his guys are exceptional. They made short work out of a massive project. I was very impressed with the cost and the guarantee as well.

  • Review 26 (2021-07-14 - Rating: 5)

    Thank you Jonathan and team Cornerstone. Your team made it possible to place our house on the market when we needed to. The repairs were done just as the foundation engineer specified and your work saved the us money on interior repairs. Timely service at a most fair price.

  • Review 27 (2018-01-26 - Rating: 5)

    Working with cornerstone foundation repair was awesome! JOnathan was quick to respond to email and came out to evaluate the problem the very next day! He was super friendly and professional!

  • Review 28 (2019-08-29 - Rating: 5)

    Jon was fantastic! Fortunately, we didnt need repairs at this time, but it was his knowledge, courtesy and communication that give us peace of mind. We wont hesitate to call him if we need repairs in the future!

  • Review 29 (2019-08-28 - Rating: 5)

    Jonathan came by today to assess the sinking corner of our floating slab. Turns out it wasnt that bad. His recommendation was measure the gap and wait and see if it gets worse. Thanks for the honest assessment and helping us understand what is going on.

  • Review 30 (2020-10-23 - Rating: 5)

    I am very happy with the job Cornerstone did on my basement foundation. It was a big job requiring skill and experience. They supported a bowing and cracked brick wall with helical piers and tiebacks, installed waterproofing, a foundation drain, gravity drains, gutter downspout drains, and replaced two large brick window wells. At the completion, they reseeded the yard, put walkway stones back in place, and replanted portions of a privet hedge that had been necessary to remove for access to the yard. I highly recommend this company.

  • Review 31 (2022-01-15 - Rating: 5)

    Jonathan was extremely professional and knowledgeable. He was prompt and prepared to answer any questions we has. He gave good advice and I as confident that he wasnt trying to upcharge or sale me on something I didnt need.

  • Review 32 (2018-04-12 - Rating: 5)

    Jon should be the first and last call anyone makes for foundation repair work. He was prompt, honest, kind, and extremely helpful. He assessed my situation and - get this - told me how to do it myself and save thousands of dollars rather than paying a company to do it! He took over half an hour to explain to me what the problem was and how it could be fixed. Then, when I asked if I could pay him for his time, he refused to take my money. Ive never seen a contractor so honest and so willing to help without being paid. Cornerstone is what every company should be.
