"Our church was build in 1920s so the scope of the project increased as the initial water damage was worst than anticipated. Waterproofone addressed those issues and, installed a french drain system, rerouted water spouts, and added an external drain behind the rear of the church. Our basement has been dry ever since and all previous water damage has been replaced or repaired."

"After interviewing a variety of companies to help us out with our water issue in our crawl space, we decided to schedule the work with Pete Westera's Basement System's USA in North East MD and we are so happy with our decision. From the first phone conversation with Tina Reaves (production manager) who scheduled our free estimate, to the estimate appointment with Tim Schlegel (inspector), to the day the work was completed by Jordan (lead technician) and Nate (assistant technician) the experience was a pleasant one. Tina was informative and easy to talk to. Tim was very down to earth, you felt like you could have him over for coffee. He explained everything in great detail and I didn't feel like I was talking to an obnoxious sales guy. He cared about our issues and fixing them the right way and the cost effective way. It was refreshing to have him break down all the parts/equipment to decided what was worth spending the money on and what we could stand to forego while still solving our problem. He created a blueprint on his laptop in our kitchen and explained every detail. He allowed us a few days to make our decision just as we told him that we need and he wasn't pushy with the follow up, but still kept in touch. His personality, attitude and sales tactics were a huge selling factor in the reason that we selected this company. We also loved the idea that the company and the owner were local to our area and that the own was a preacher. They also have an excellent warranty that covers the life of the structure making it comforting to know that the warranty can transfer through multiple owners without any "fine print" snags. They originally had the next available install date about 30 days from the day we received the estimate. Due to our busy life schedule, a honeymoon, and the upcoming cold weather we were in a time crunch and requested to have it done in 2 weeks. Tim and Tina made some calls and made it happen, again helping us out big time. The week before the install we were out of the country on our Honeymoon and I communicated with Tina asking that she reach out to my Mom in the event of any last minute changes, she made a note on the account and everything went smoothly. The install crew arrived on time and the lead Jordan was excellent at communicating with me from the time that they arrived to the house, to excellent detailed description of what they we actually doing as they performed the work, to the time they took a brief lunch break and the follow up the following day when he had to return to finish the drain outside. They were both very courteous, they worked very hard all day, they were easy to talk to and maintained a very clean work environment both inside and outside of my home as they completed this project. The company also offers a financing option of up to 6 months with 0% interest which was very appealing to help us pay off this project in a timely manner without racking up another high interest home project credit card. From start to finish we couldn't be happier. Now 5 days post install I am happy to report that our system is operating properly and it was well worth the money (a very competitive price I might add) to have the piece of mind to know that we received quality workmanship and to no longer have the fear of further expensive water damage or cringing every time that it rains. Thank you very much to Basement Systems USA and their entire team. I will be sure to pass your name along to anyone in the market for your expertise!"

"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!!"

"QUICK, FRIENDLY, and CHEAP!! First, AJ called me within 30 seconds of me texting him asking for an estimate. I sent him a photo of our water leak issue and he immediately responded. He actually explained that we could probably handle the repair ourselves if we were up for it, instead of paying him or someone else. He then walked us through every step in detail and made sure we were comfortable with the directions. So in the end, it cost us $0 in labor and only a small amount for materials, and really demonstrated AJ's integrity and generosity!"

"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!!"

"I highly recommend DryTech for basement foundation repair. Steve Lombardi was amazing! He walked me through the repairs I needed, educated me on the process and was able to schedule the repairs quickly. On the scheduled day for the repairs, the team (Carlos, Alex and Derek) arrived on time. They were very professional and worked quickly. They had to dig up my front and side yard to get to the repairs. After the job was completed (only took 1 day) you cannot tell they were there! They did such a great job on putting everything back in the correct place (including bushes, landscaping lights and mulch) it looks like nothing was done. I could not be happier that I selected DryTech for the job. Do yourself a favor do not waste time looking around- hire the best!"

Foundation Repair FAQs, answered by experts

In order to raise your home to make foundation repairs, you'll need to bring in a structural engineer to help you design the project. You'll also need to see if you're eligible for the permits needed, and contact a foundation repair company near you.

Efflorescence can damage a concrete slab for two to three years. After that, it resolves on its own once the surrounding salts are gone.

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. 

A slab-on-grade or slab foundation is a great option in many areas—usually in warm or moderate climates—and has been a successful foundation style for many decades. Slab foundations don’t require excavation or concrete block wall construction, so they’re the least expensive foundation type. They’re also the fastest to construct and don’t have many issues with moisture or water intrusion. However, they don’t give you extra storage space or potential living space like a crawl space or basement would, and they’re not ideal in colder areas where utility lines can freeze and frost heave can cause major damage.

Yes. Foundation walls are always load-bearing.
