What Our Customers Say

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.

Jonathan's 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.

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!

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

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 home's foundation is now is now "better than new."

We had some pretty bad wood rot in our crawlspace. Jonathan, of Cornerstone, did a great job of following the engineer's 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.

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)!!

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.

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 didn't 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.

Trustworthy company!

I was referred to John after calling several companies who said that they couldn't 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 couldn't raise the pad but John's crew was able to raise it some. Grateful for his expertise, professionalism and rapid response. Highest personal recommendation for John and his team.

John came out, then never sent me an estimate... kind of funny that he emailed me right after I posted this asking me to remove it... I didn't receive a call/text/email from you till now. Three stars assuming technical error. Better communication / some sort of follow up is needed mate

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.

They repair my foundation and they broke a drain pipe that was under the house. It was not a utility pipes that come out of the house so there’s no way I can locate it before repair. The guy that was doing the repair knew he hit the pipe and leaking, instead of patch it up he just put the dirt back and cover it up. Now the whole backyard is black water coming out of the pipe.

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 wasn't trying to upcharge or sale me on something I didn't need.

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.

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.

I bought a 1960's single-family home that had structural issues, and received a copy of the seller's 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 I'm 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 don't really trust contractors that are good at paperwork.

Very prompt and professional! I would recommend them for any foundation issues!

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!

BE CAREULL. Do not sign a contract without reading both pages. He had me write a check (did not accept credit card) for 50% down on a large project over $28,000. The first page says you can cancel within 3 business days. I called to cancel with 1 business day and asked he hold the check until I got another bid. He was recommended by a structural engineer so I did not check BBB. (no positive reviews found). BIG MISTAKE. He cashed the check anyway and when asked to refund the check, he then said he would keep 10% for processing, I then found hidden on the back page with all the warranty information, slipped in the line "10 % for processing". Never shown to me during the contract signing of both front and back page. Its been 2 weeks and he has not sent back any of my large downpayment.

Jon was fantastic! Fortunately, we didn't need repairs at this time, but it was his knowledge, courtesy and communication that give us peace of mind. We won't hesitate to call him if we need repairs in the future!
