Groundworks is absolutely fantastic! The crew that came to our house was by far the best I've ever worked with. They were friendly, quick, and did wonderful work! Our foundation was already moved 2-3 inches back by the time they left! They even helped level out some extra dirt we had sitting in the yard with their equipment. I would 100% use Groundworks again and have even referred them to multiple people already!

I wish I could give them -10 stars. This is the first time I have ever gone out of my way to give a poor review (I give many positive ones). I had a truly terrible experience with Groundworks. They installed a sump pump in my basement so that I could mitigate a one-time water problem and prepare my home for a pre-inspection to put it on the market (that's really the only reason I invested the thousands of dollars. Then months later puddles of water were collecting on the basement floor even though it wasn't raining. Turns out the crew didn't seal the PVC joints for the discharge and water was coming IN the exterior discharge and leaking on to the floor. In other words, there install CAUSED flooding in my basement. I called three times to finally get someone to come address it. He came 40 mins late. I had to leave while he worked and he assured me that the problem would be resolved and the floor would be dry. 45 mins later he called to tell me that he "fixed" the problem, but he spilled water all over the basement. He had one 5 gallon bucket to catch the water, but it was not enough. See the photos for the result. Remember my home inspection? It's tomorrow. I'm completely screwed and it's completely this company's fault. When I got home to review the damage I found the sump pump left unplugged. Honestly, pretty unbelievable. Again, I am the furthest from a complainer. I'm a generous tipper and an all-around decent dude who treats my own customers well. I do, however, pass along my experience as a cautionary tale for anyone considering Groundworks.

First of all, here was our problem: when there was an EXCESSIVE amount of RAIN, our basement would FLOOD to the tune of at LEAST 3 to 5 inches. So we did some research and decided that GroundWorks would be the company to go with... Their Rep (Zane Mitchell) was VERY professional, and gave us a pretty good insight into our options (no pressure), what to expect, and also how the process would flow. Afterwards, after committing to their work, there were pretty much NO surprises, as this was a process that is/was very NEW to me. THEN came the ground crews. These guys were VERY professional - and were considerate enough to inquire of us if there were any issues wrt decisions to make. I'll ADMIT: when Zane told us that these guys would be FINISHED in THREE DAYS, I somewhat DOUBTED that -- but he was CORRECT! These guys COMPLETED the job in THREE DAYS! And -- they EVEN TRENCHED an underground DISCHARGE PATH EXACTLY where we ASKED them to place it! When the completed the job, they took us on a tour through the work area to ask if there was ANYTHING that looked out of place or not completed. We were pretty satisfied. They even cleaned up the work area (e.g., our whole basement) fairly well. From what I saw, I'd DEFINITELY recommend this company to anyone having the basement flooding issues we were having!

Price and Mariano came at specified time and injected our front concrete porch to raise it. Prince explained and showed us what they were doing. Very professional and slab is raised! Would highly recommend!

prompt service

5.0 Margaret L. Evergreen, CO

What I appreciated - aside from the quality of work - was that when issues occurred, I was notified immediately. If someone makes an error, they admitted it and took immediate action.

I paid $13,000 for foundation repairs that did not ever address the 3" of sinking floors to the middle of my floors, after getting 2 separate opinions/quotes from Groundworks and Peak Structural, Inc., owned by the same company. Recently, I have not been able to get in contact with anyone to address my original concerns.

5.0 Sheryle C. Aurora, CO

The team did a great job, very professional and clean

You spend weeks choosing a contractor, you book months out because of availability, they stress your requirements to get the project done, and then they do not show up. I had to call them to find out they were pushing my job a month. No warning, no seeing if I could support the new date, after I did my part and took the day off and got a dog sitter. Groundworks, your customer service is atrocious.

1.0 Bill K. Watkins, CO

I hired peak structural to prevent water from coming in my home. They are now Groundworks. And only dowork under ground. My entire home is under ground. Peak Structural worked on it. With our recent rains, I had a leak from the area I paid to make sure I didn't have a water issue. 2 to 3 gallons a day dripping frommyconcrete ceiling which is under ground. I now tested positive for mold right below where you worked on my home. Any good company would back up their work. But ground works says they don't owe me shit. I think they do . So you 1 last chance to fix it before I file suit. 720 366 0963. I don't want to hear anything other than you will fix it.................no more bullshit.
