High pressure sales tactics, upsell at all costs. Had an agent tell me I had $120k in foundation repairs or else my house would crack like the titanic. The next day an independent engineer said everything was fine and I didn’t need to do anything. Absurd business, now owned by PE.
Have had inspection, and intend to follow the recommendations and have the work done. The inspector, Alex, spent several hours at our home, and did a very carful and complete inspection, including entering tight crawlspaces that must have been an uncomfortable task. The report was detailed and I am confident as to the validity. The recommendation appears reasonable. Alex explained it clearly and he patiently spent as much time with us as my wife and I needed. I look forward to having the work done.
I had the pleasure of working with Mark Brill to get a better understanding of the work that’s needed to repair my foundation. He was extremely thorough on his inspection and a really went into detail on what he found and what the next steps would be. I wouldn’t want to work with any other company that Groundwork’s from now on.
Mark Brill was fantastic in his assessment , very thorough and spent time making us understand the problem and solution . He gave us confidence in the company’s value .
UPDATE 12/22/2025: After submitting my previous review, I was informed by my contractor about some serious shortcomings in the work performed by Groundworks. We discovered that some of the screwjacks were not properly installed and even found that some were not supporting the girders at all. I reached out to my sales contact at Groundworks for help resolving this initially on November 22nd and received response that they would notify the Production Team about the issues. I followed up approximately every week for a month to get some resolution to the poor quality work from Groundworks, but never received any communication from the Production Team at all and had to contact another contractor to have the faulty work fixed. Very disappointed in the work that was uncovered by my contractor, as it is evident that some of the work may have exacerbated the problem we were trying to address. ORIGINAL: Ramon and his crew were exceptional in their communication, performance onsite, and consideration for the neighborhood while they helped me to stop a sinking foundation. Although we ran into issues with the work, Ramon and I were able to work through them to bring the project to an acceptable completion and ahead of schedule. I would recommend using Ramon & Groundworks to address your foundation issues!
Our technician, Nicholas Mahoney was very knowledgeable and thorough about our problem. He was friendly and took his time to explain everything the company did. He showed us the reviews, and he looked not only in the inside he went in and inspected our crawl space. He inspected the outside. He used special equipments to make sure we were level in all our places. Nicholas was very professional and well-mannered.
