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.
