Groundworks did an excellent job with my house projects. Their crew (Lee, Rick and Brad) were excellent. They arrived ahead of schedule and began work immediately. I was kept informed every step of the way and was invited to observe while they explained what they were doing. I would highly recommend Groundworks to anyone needing foundation stabilization.

Had to address groundwater issues under my modular as a result of home inspection as house is for sale. Michael came out and provided an estimate for a sump pump system after determining water issues were related to groundwater. Not gonna lie, was a little breathtaking. Other estimates came in close or a little lower but I liked the system Groundworks used. I also liked the life time warranty and it is transferable to new homeowners. Based on reviews I researched they appear to be really good at honoring their warranty. He was able to coordinate getting the work done prior to closing which did not give them a lot of time. That was another reason I chose to hire them. The crew that came out, Travis D, Garrett and Beau were awesome. The crawl space under my modular is tight so I know this was not an easy task. Hard work and hard workers! I would recommend them for the type of work I had done. Very pleased!

Nick and Tyler did a great job today understanding how the caulking and existing concrete work together, was thorough in their explanation of the process, was professional and cleaned up well. Thank you!

Basement Waterproofing
$25,000
After heavy rain we had Groundworks mitigate water in our basement. They drafted a plan and advised on how to prevent water intruding on the east wall of our house, which consisted of a front and back bedroom. The water was currently only entering from the back bedroom, so Groundworks advised to put in an interior french drain and waterproofing. My wife and I specifically asked whether we should also mitigate the front bedroom, and they advised against because it would entail losing the bedroom closets, and the existing plan would mitigate water for the entire side of the house. We also specifically asked if we had water intrusion later in the front bedroom if it would be covered under the warranty and they confirmed that it would be covered. Now less than 2 years later, I have water in my front basement bedroom every time it rains. I have contacted the company repeatedly, and while they initially, verbally stated that they would correct the work and make things right, they have since claimed that the warranty only covers the back bedroom. They are now advising to do an additional assessment, and for me to pay for additional mitigation. In total, the sales tactics seem unethical, the customer service is atrocious, and I would never pay Groundworks to complete work on any project again. I strongly recommend everyone stay as far away from this company as possible.

Mike and Tyler did a great job leveling our bedroom slab. Very professional and thoughtful in their approach to the project. This is the fourth time we have used groundworks on two different properties. I would go with no one else.

Tyler and Nick were tremendous. Tyler explained everything clearly before beginning and after completion. Job site was left cleaner than it was on arrival. Sales phase (Mr. Clough I believe) was also very professional and compassionate. ( he could sell sand in the Dessert)

AWESOME!!. First KUDOs to Mike and Tyler, very professional and did an outstanding job. The Groundworks team were great from first contact to getting the job done. A special shout-out to Mike and Tyler for their honest work ethics, explaining everything, completing the job, cleaning everything up afterwards and it was raining the whole time. We would hire Groundworks again. Thank You.

Mike and Tyler were very professional and did a wonderful job of not only completing the job, but also explaining the process along the way. I will certainly use Groundworks again should something similar arise.
