Our Services

Foundation Repair
Do you know how well your home is standing up to the test of time? Is it strong and sturdy or does it feel like it’s on shaky ground? Whether you interpret this figuratively or literally, it’s so important for your home to have a strong foundation.

Crawl Space Repair & Encapsulation
Normally these areas are empty, but you never know what creepy conditions you’ll find there – mold, pest infestation, wet insulation, and much more.

Basement Waterproofing
Water is essential, but other than coming out of faucets for specific needs, you do not want water in your house. This powerful element and force of nature can wreak havoc on your home.

Structural Wall Repair
Repair your failing and crumbling structural walls with our proven products.

I had IBA install a mix of Intellijacks and carbon strips in on one of my basement walls. Dylan really hung in there on the prior project and came up with a workable solution for me — I felt he went far out of his way and demonstrated care that is rare.. During the yearly follow up for that work (which is holding up), it was identified that some Intellijacks for foundation beams would help solidify my house (the beams were wood and not large enough, so the house was shifting). Ricky did a great job explaining the situation and my options. He also spoke at length with me and took time to help me understand when I had questions and got confused. Jeremiah T and Mark F. did the work and were excellent. It was invasive work, but they were pleasant to be around, communicated clearly, were fast, and kept the mess to a minimum and cleaned up afterward. No one wants to have this sort of work be necessary — IBA was recommended by a construction friend and I agree they are a good choice if you do need this sort of work. Professional, thorough, and guarantees included with their products and work.

I had John with Groundworks come look at house after learning my floor was out of level. He drove over and hour each way two times and spent hours in my house measuring, and hours more on the phone with me and discovered a wall that was out of plumb due to rotted supports on an overhang, causing the overhang to pull on the wall. He gave me a $13,000 beam and interior support pole proposal that he said they could do in addition to the overhang supports needing to be replaced by a different contractor, but told me point blank that what he had proposed would likely be for peace of mind only and likely a “net zero” benefit after the supports were replaced by a different contractor, so there was really no need to go through with the work from Groundworks. He could have easily told me their proposal was necessary and I’d have paid it in a heartbeat. Hours upon hours he spent working hard on my issue, identified the issue, told me how to solve it, and Groundworks never charged me a dime, even though I’d have bit hook line and sinker if he told me the proposal was necessary. Really unbelievable level of effort and integrity, I was amazed at how passionately he cared about solving my issue in the best way for me. Once in a lifetime experience.

Chad J was an amazing inspector! I have a home in South Minneapolis with efflorescence and he walked me through all my concerns and then completed a thorough inspection.

Jeff came out to consult about my driveway. He walked me through their process and types of materials the company uses. Overall, great learning experience and price! I flip homes and to learn this company offers warranty transfers to new owners is amazing! Very happy with the visit I had today and look forward to the scheduled work.

The installers Isaiah McKeown and Chris Popouich, called us the day before and the day of the installation to let us know their arrival time. We walked through the project site and reviewed the contract. They answered all questions we had. As they installed the product, they were very careful and protect our property. After the completion of the project, they cleaned up and walked us through the project site. Both Isaiah and Chris were very professional and helpful. I would recommend this company and this crew to anyone. Thanks again for the outstanding job.
