"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."

"Basement Gurus arrived to discuss our basement water issue. Dan patiently went over everything and listened to our concerns and answered our questions. He prepared a proposal to remove 4' of our patio and dig down to the foundation to waterproof the wall and fill the cracks from outside. He also suggested burying a downspout and pipe leading water away from the house and sealing the wall cracks on the inside basement wall. The team arrived as scheduled and worked incredibly hard for several hours a day. They were impressive in the system they followed and how much work they performed each day and were respectful of us and our property. By the end of the job everything was back in place. We wish the expense wasn't necessary, but felt the price was worth it due to the difficulty, the amount, and the quality of the work. We highly recommend Basement Gurus!!"

"If you’re looking for work done the right way. AFS is who to call. I had an emergency repair needing done on UTC campus and that day Mike came out and gave a quote and scheduled service that day. And let me tell you when the Mattgican ( Matthew Martin) and the Parrbear ( Parris Houchins) showed up on the job ( exactly when scheduled) they went straight to work and did such a fantastic job explaining what they were doing and why I knew I made the right choice in calling AFS. If half of their employees are as nice and hard working as those guys anyone they send will be top knotch. Fantastic job guys. You made my day a lot better. Great company don’t hesitate to call them. I’d give them 10 stars!!! Won’t be calling anyone else!!"

"The entire process went extremely well. The estimate was very clear about the scope of work, the crew was professional, on time and carefully about reducing disruption/mess and our basement is dry, as promised. They even went above and beyond and fixed a downspout outside so water would flow away from the house. Once the job was finished, the company rep came out to walk through with us and answer any questions. I have no doubt that if a problem did arise, they'd fix it."

"Customer service was on point. They came when they said they would, they did what they said they would. No hassle, no games. I had a foundation crack in my basement wall which was leaking every time it rained. They came on time (and it was snowing) for the free consultant. Estimate was provided on the spot. They came on time to do the job and did exactly as was described/on the contract. We then had a heavy rain storm the weekend after and the basement is dry."

"Led by Brett Boyles (foreman) out of the York/Red Lion area; Brett, Clarence and John took care of some flooding issues that have been plaguing us for years. They fixed cracked cinder block walls, they put in a BDry system that is BEAUTIFUL, they turned a passive French-Drain system into an active system, and they turned an unhealthy basement into one with healthy air quality. They worked so hard and were so courteous, I feel so much more relaxed now. Brett knows his stuff and the other guys were awesome as well. I am so grateful...NOBODY ELSE will touch my basement ever again.....only 58 Foundations!!! Thank you guys, very much. Sincerely, Dan Crum"

Foundation Repair FAQs, answered by experts

If your foundation is unfinished, has surface damage, or is just plain unappealing, foundation refacing can be another great way to increase your curb appeal and give your foundation a fresh look. Used in conjunction with foundation planting, refacing can completely change the look of your foundation and your home. 

Signs of structural damage include foundation cracks, roof leaks, bouncy floors, crumbling concrete, and cracked or leaning chimneys. Structural damage can make itself apparent in various ways, and sometimes, there may not be obvious signs. Inspect your foundation and roof annually to stay ahead of potentially serious structural problems. 

While it can be difficult to identify a bad foundation at first glance, look for large horizontal cracks, discoloration, bulging basement walls, or signs of water damage. You may also see large gaps between the home and the foundation on the outside or signs of pooling water from a recent storm.

In most cases, it is safe to live in a home with minor foundation problems, but you should not let the issues persist. Virtually all foundations have small cracks from normal settlement, which are not a structural concern but should be sealed to prevent water intrusion. However, major damage—such as large structural cracks, sinking foundations, or bulging walls—can make a home unsafe. Other issues that can pose safety and health risks include poor indoor air quality from mold or pests, uneven floors, and rotten beams or joists. It is always best to have a foundation repair expert or structural engineer inspect any issues to determine if your home is safe to live in.

You can buy a home with foundation issues, but understanding the extent of the problem and what solution you need is critical. If you learn that a home you’re trying to buy has a foundation problem, it’s not necessarily a deal breaker, but you should have a professional assess the issue to see how severe it is and know when to walk away from a foundation problem. Foundation issues can necessitate simple and affordable solutions or complex work that costs thousands.
