"Josh, the representative from Basement Gurus was outstanding! We had experienced a water issue in our finished basement. Josh thoroughly examined the interior and exterior of the home and determined that the leak might be plumbing related. Josh could have very easily exploited our ignorance and suggested a solution purely beneficial to his company that may not have addressed the underlying cause of the problem. Instead, he demonstrated his integrity by realistically assessing the situation even if it would jeopardize the sale. This is commendable particularly in this era where cutthroat business practices are commonplace. I highly recommend Basement Gurus. They are fortunate to have an employee like Josh who exhibits concern for the customer at such a high level. "

"Service was great from sales, to installation, to post installation support. Very responsive, very professional. It's hard to find in this 'space'--there are a lot of shady people in basement water damage/repair, and this place exceeded expectations. We've had our repair in place for 4+ years, with only 1 small issue on a wall seam crack, and that was fixed within 24 hours of reporting the issue. Stand up place! Thank you for such great service and support."

"JES Foundation Repair (A Groundworks Company) proposed a solution for my basement wall reinforcement, and waterproofing. I accepted, and a date was set. They did not show up and it took 8 phone calls and 24 hours to find out that they weren't confident in their proposal. They increased the scope and added 50% to the cost. Stupidly, I signed again as time was wasting and I didn't want to start over with new vendors. JES completed the work while I was out of town. When I got back, there had been heavy rain and there was more water in my basement then I had ever experienced. I contacted my rep via text (impossible to get through by phone as he always was in "Training" when I called). His response was " That doesn't look good, I'll make some calls". I had to make the calls. JES sent several new employees out and they proposed additional work at ADDITIONAL cost. Unable to get satisfaction from mgmt. Had another foundation company finish the job. Do not use!"

"The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!"

Foundation Repair questions, answered by experts

Not all cracks in the basement floor signal foundation problems. As the house settles, you’ll notice very thin hairline cracks, which you don’t need to worry about. Cracks that are 1/8 inch or wider should require sealing, while ones that are 1/2 inch or wider require leveling. However, if you have cracks in your basement floor with heaving, you should call a pro to assess the situation. Heaving can lead to uneven flooring, structural issues, and foundation problems.

Foundation repair costs $250 for a minor crack that doesn’t affect the structure’s integrity, although it can cost as much as $800 if it’s a major crack. Call a pro to get it fixed as soon as possible if your crack is bigger than 1/8 inch wide. Additionally, if you need to seal the foundation to fix leaks, it can cost approximately $2,000 to $7,000.

If your concrete steps have crumbled or chipped, you can fix them by removing any chips or flakes, cleaning and wetting the affected area, applying a concrete bonding agent, and finally applying new concrete, usually in the form of Portland cement. For widespread damage, you can consider concrete resurfacing instead. For fixing concrete spalling that has led to deep damage, you might need to remove damaged material, add structural supports, and pour new concrete into a mold.

Yes. Foundation walls are always load-bearing.

Concrete pools are very durable but can crack if not properly maintained. The most significant risk is winter weather and low temperatures when water can seep into crevices and freeze. To avoid damage, use the proper winterization chemicals, and don’t completely drain your pool. Concrete pool repairs cost around $75 per linear foot for small cracks.
