Michael B at Groundwork’s did such a great job inspecting our sump pump system and all the basement work we have had done to keep our basement dry and safe. I have truly appreciated this company and every person that has been in our home. He had a trainee with him today who did great as well. Thanks Michael for the great inspection!

Ricky was the technician who came out for a maintenance visit for work we had done a few years ago. He did a great job explaining the inspection he did and the findings. I'm hoping we can work with Ricky in the future on any further work.

We had our garage floor leveled and cracks filled and a basement wall waterproofed (gutter system with pump and wall seal) in Minneapolis in 2024. Both projects were done by people who take pride in their work and strive for the best outcome. Our garage floor was in sad shape, and Andrew spent extra time to get it as level as could be and filled the many cracks thoroughly. One side of the garage went up 4 inches to make it level again. As for our basement, Jeremiah T, Dion R, and Jaden R did a great job installing the gutter system under the floor with the pump, drainage, and wall seal membrane that went with it.

Although the crew was unable to complete the job we had expected, Andrew was amazing to work with. He kept us abreast of everything they ran across including what might happened if they moved forward. He was very informative and helpful. He also contacted other engineers to confirm his decision. He went far beyond helping us, he even assisted us in finding a sub contractor to rebuild the basement wall and sent them measurements and pictures of the space. He is working on getting our down payment returned. Devon and Dion were great to work with as well, friendly and hard workers. Would definitely recommend all three of them.

Dustin, Keiren and Jaden did a great job on the basement. There was a design concern upon arrival and Dustin brainstormed with me and the engineers to come up with a viable solution. There called ahead, kept me updated on the progress all along the way and took time to answer all my questions. I would use Innovative Basement again.

Had John Anderson in from Groundworks to inspect basement on pre-paid inspection. Very friendly, professional and helpful! Suggested a reconfiguration of our dehumidifier that allows us to have more space in our utility room. Highly recommend!

I called Groundworks due to a sinking sidewalk and driveway issue on my 1-year-old build that I had purchased 6 months ago. Groundworks sent out John Maness who was the most professional, and knowledgeable inspector i have ever dealt with when dealing with companies that provide home services! Even though the company is located in Fargo, they sent him out in less than a week, and he was willing to work around my busy work schedule. Johns thorough attention to detail when inspecting my home highlighted not only the issue with my concrete, but also a few hidden issues with moisture that I did not know that I had. John was prepared with all the tools and knowledge necessary to inspect my house, and had a proposal ready to fix my issues within 2 hours! What was even more mind-blowing was the actual cost to repair my concrete, and mitigate the moisture issues that I had with my home was beyond reasonable!!! Also the after service care and service that will come with my repairs and equipment is amazing!!! This company is top-notch and they will not sell you anything they do not need. I had other questions about some things that I noticed with my foundation that i had concerns about. I was informed by john that they're not here to sell me something that I don't need and he was able to show me why the the perceived issues that I had were in fact not an issue. The whole process of repairs were outlined in easy to understand videos showing the root cause of my issues and how they can fix those issues permanently, not just a bandaid! The best part about it is they will come out annually to check their work and make sure that everything is still in working order, and that the repairs that they have made on my concrete is in fact still doing its job!! They had many options for payment to include financing at an amazing rate if someone were unable to afford the repair costs. The whole process was smooth and painless. I would 10/10 recommend ground works for any foundations issues that I had to anyone!!!! Thank you Groundworks for helping me protect my investment!

There was a few communication issues at first with the company but Andrew reached out and fixed the problem. The young men that you sent down to do the basement Noah A, Deion R and Mark F was absolutely amazing, so polite and helpful, they answered all my questions and explained what they did. They had everything done with in a couple hours and made sure all the mess and materials they had to use was cleaned up really good. Please tell them thank you from me for doing such an awesome job.

Jeff was straightforward and compassionate in a very stressful pseudo crisis basement situation, getting us through the inspection/assessment process, proposal and scheduling the project all within 24 hours. He communicated clearly and rolled with all of my questions and ‘big expensive decision’ jitters – addressing my concerns without making it worse.

Service technician Michael Bowers came to our home for our annual inspection and to look at a specific issue we’d been having. This same issue had been looked at by another source a year ago with no resolution. It took Michael less than 15 minutes to assess and find the problem. He explained everything to me and had it resolved that afternoon. Beyond his repairs, I found Michael to be a warm and personable individual, taking time to listen and understand my questions and concerns. I appreciated his time and attention to all we discussed related to our home. He made the entire visit easy and pleasant.

David drove out of his way to look at our basement issues. He sat down with us and really listened to our issues. Then he did a thorough inspection with pictures. He then sat down again with us and went over a plan that fits our budget and goals. Highly suggest working with Groundworks for your basement needs.
