    5 star review  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.

    5 star review  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.

  • 5 star review  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.

    5 star review  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!
