5 stars for Miguel, Daniel, and Juan. They installed a basement waterproofing system and sump pump in our home, and we couldn’t be happier with the experience. The team was professional, communicative, courteous, and clearly took pride in their work. They paid close attention to detail, kept the area clean, and worked through a few project-specific challenges with thoughtful problem-solving and craftsmanship. They took the time to answer our questions and made sure we understood the system before wrapping up. Great crew and great experience overall. Highly recommend Groundworks and this team.

So so so happy with this project. Big shout out to Dominic and Eamon for getting this sump pump and down spout extension installed. I was having ground water come up into my garage and needed a solution. Eamonn was the foreman and his team is very clean and professional. Dominic was my project advisor and he was very pleasant to work with and used laser level to measure sinkage of my slab, checked my foundation perimeter , and drew up my house layout so when I was ready to do the project a year later he was still able to reference the layout of my house . Would recommend to a friend for sure

UPDATE: The company reached out immediately after seeing the original post and came out to review the work in person and then sent another team to repair the concrete that had been damaged. The concrete crew was headed by Dylan, who did a great job and was very personable and communicative. The original pictures are now patched up and and while things didn't go as smoothly as I'd hoped the company did ultimately get things handled and I'm content with the final result. ORIGINAL POST: Probably fine for simple jobs but doesn't seem to handle more complicated jobs well or stand behind a job to completion. I contracted Groundworks to try and lift some concrete slabs around a pool I had just purchased. About 2/3rd of the pool was pretty simple and those seemed to lift into place just fine. The back of the pool concrete was a bit more nuanced and would be trickier, which I fully understood going in. It felt like there was only one thing they could do so they just tried the same approach on that concrete (which was not what was told to me by the sales associate) and that ended up cracking the concrete in several places per the below pictures. I knew it was a tougher task and that was possible but assumed they'd at least patch any cracks and was not expecting them to disturb some of the existing structure as much as they did. The large chunk that broke off was tucked in for the rushed walkthrough and 10 minutes after they left I walked around for a closer look and saw the cracks and broken concrete. I reached out with pictures to see if the cracks could just be patched up so water didn't infiltrate the concrete and was told they'd look to fix it quickly but after a week, and a follow-up, with no response I'm less optimistic and will now have to start searching for new contractors to fix the damage left behind. Everyone was nice and for small very straight forward jobs it probably works well but I'd look elsewhere if your job is complicated.

UPDATED ON 7/2/2026: The company reached out immediately after seeing this review. They sent a crew the next day to fix the issue and fully address my concerns. I am now happy with the results, though I wish it hadn’t required a public post to get this matter resolved. ORIGINAL REVIEW: I got several quotes for crawlspace encapsulation and chose Groundworks because the price was competitive and their inspector, Mark, promised 12-month interest-free financing. I was explicit: seal the ground, the walls, and the rim joists — no surprises, and nothing with moving parts to maintain. He talked up a $3,000+ dehumidifier and a "maintenance service" anyway; I said no to both. He confirmed everything I'd asked for was covered, then buried vague product names in the contract instead of plain language. Right before signing, the financing "promise" vanished — suddenly I needed to spend an extra $1,500 just to qualify. Red flag #1, but I'd already invested weeks of planning, so I paid by credit card instead. The crew finished in a couple of hours. Then I noticed they'd skipped the rim joists entirely — just running a foam board from floor to subfloor — leaving my house exposed to the exact cold-air leak I paid them to prevent. When I called, they said it "wasn't in the contract" and wanted more money to fix their own mistake. What followed was weeks of empty promises: an apology that led nowhere, ghosted messages from someone named Steve Moran, and a receptionist who told me the salesman "doesn't work here anymore" — as if that fixes anything. The tape is peeling now. The warranty is worthless. Don't let this happen to you.

Groundworks installed a french drain for us today. The sales rep, Edward Jones was friendly and knowledgeable! Answered all my questions so I completely understood what our water issue was and how to resolve it. I had total confidence in this company after he left. The crew showed up right on time and went over all the details of the job to be sure we were on the same page. I cannot give this crew enough praise. Polite, respectful, hard working, extremely organized from their truck supplies to the way they layed out their work and they left my basement and property spotless. Ramon, Daniel, Miguel and Anthony were the crew members. They really enjoyed working together. Have to give a special shout out to Anthony, the newest member of the crew. This young man was so excited to work for Groundworks and spoke passionately about his future. That says a lot ! This is the company you want to do your work. YouTube Mike Rowe/Groundworks for some great videos.
