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.

Well, this is the second time I’ve had groundwork’s come do a project, the first time, they waterproofed part of my basement, this time they finished it. I will let the past be the past, there is no sense in bringing up old dirt but I will tell you I was very skeptical about calling them again. I almost went with a whole new company to come in and just see what they could do so I didn’t have to deal with them again. This time around was so easy and so quick, the crew that came out was very knowledgeable and so kind. When John my sales tech came out, I think he was here for around 4 hours! While I drilled him with questions, he was very patient and understanding of my concerns. I am very happy with the way it turned out and I would recommend groundwork’s to anyone looking to waterproof their basement!

My concrete entrance to garage and house was shifting. It created a significant bump to get in the garage and a trip hazard to the house. To replace the driveway would have been a big hit financially. Groundworks was a great solution. They adressed the slabs and apron that were causing the issues. When they were done everything was level and the garage entrance was back to the slight bump that it was originally. The process was really cool to watch and the finished job was exactly what I was looking for. Great job. Thanks Marc and Brandon.

On 12/4/25 the Rush City crew was out for 2 days to remove pavers & a ramp from the garage then dig up floor to make a trench to install anchors to the back of the brick wall which was bowed. Each of the crew (Austin F., Andrew W., RJ, Brandon & Dakota) was friendly & the foreman gave us constant updates on arrival times, access to garage, etc. We would highly recommend them for future projects.

We requested a technician to come out to evaluate some concerns we had but after a thorough inspection we were assured that our foundation and the prior work that was completed by Groundwork’s was indeed sound and working properly. Big shout out to Michael Bowers for providing excellent customer service and professionalism. He took the time to make sure all of my questions were answered and concerns addressed

Superior workmanship and customer service above and beyond as always by Gregg P and Brandon S. Groundworks has always been excellent the multiple times for different issues we have used them over the years. Gregg and Brandon very much lived up to those standards. They were patient, thorough and followed through during a somewhat confusing situation to get the job done well and take care of us. Big shout out to both of them and this is exactly why we keep going back to Groundworks and also keep recommending this company to friends and neighbors! Thanks again Gregg and Brandon!

I really appreciated working with Innovative Basement Authority with securing my house in many ways (Piers, foam, beams, etc.) amounting to many different projects completed at this point. I had five competitive estimates from other companies but the guarantees, price, and options provided by Innovative were hard to beat. Since working with them, their customer service has been top notch.Piers/Beams – Lance and Kyle were the BEST. That was one intense job to dig up the basement and install piers/beams. They were knowledgeable, helpful, conscientious of the house, and personable to work with. They deserve 10 stars.Estimates – Thank you to Chris and Travis for the competitive estimates. Chris was always willing to work with me to provide the most competitive quote with good options. Travis has met all the challenges with insulation and foam. Thank you for all the follow up as well.Foam – Front Steps – Gunnar and Logan stabilized my front steps with foam. They were very considerate of walking through every step, the risks, and the warnings with completing this job. I appreciated their customer centric approach.Foam – Basement – Mark and Andrew were great as well with the basement foam insulation. They too walked me through the expectations of the job and it was a very smooth process.I'm sure I have missed some people who are part of the process. I can tell this Company works as a team which is appreciated. I'm grateful to you all.I feel my house is in great shape to last the next 80+ years. Mostly, I believe I can count on Innovative to be there if there are any concerns in the future.

Brandon C. , Roel L. and Zack B. Did a great job installing our new sump pumps with backup battery. They also insulated our crawl space which will keep our kitchen and dining room floors warmer this winter. They were very easy to work with and answered all of my questions. I wouldn’t hesitate to use them for future projects.
