"I recently had the pleasure of working with Oswaldo and his team for a foundation repair project, and I couldn't be more impressed with the service they provided. From the moment they arrived at the job site, Oswaldo displayed exceptional professionalism and expertise. He quickly assessed the areas that needed attention and promptly updated the repair plan to ensure it met the specific requirements of the situation. Despite facing challenging weather conditions—snow and ice melt, followed by heavy rain, and an unexpected flow of water under the house—Oswaldo and his team showcased remarkable perseverance. Their dedication to completing the job, no matter the obstacles, was commendable. Additionally, I appreciated Oswaldo's commitment to communication. He kept me thoroughly updated on the project's progress and any necessary changes, which provided me peace of mind throughout the process. Overall, I highly recommend Oswaldo and his team for any foundation repair needs. Their experti"

"Howard Glancy came to inspect cracks in my home's concrete walls where the foundation was sinking. He, as a Certified Field Inspector, went over the whole house with me, explaining why the walls were cracking, and what should be done to alleviate the problem. Howard explained what JES Foundation would do, approximately how long it would take, and provided a quotation for the repairs. Besides raising the problem walls and ensuring they would be structural sound and guaranteed to stay that way for the remaining life of the house, he also advised me of how JES would repair minor cracks in the remaining building as well as having s sump pump installed to wick away any ground water from damaging any other parts of the structure. Mr. Glancy was very courteous; knowledgeable of his profession; and walked us through any questions we might have had concerning the processes. Due to the permit process taking so long, the work on the house won't start for a few months, and if Mr. Glancy is any indication of the professionalism of the rest of the JES Foundation personnel, I'm confident that the work will be done properly, in a timely manner and to my complete satisfaction."

"This past year, as we were removing the old wood paneling in our basement, we found a diagonal crack along one of our exterior walls. If a crack in a wall is not terrifying enough we had signs of previous water damage and the possibility of a crack in the foundation. We called AA Action Waterproofing to give an assessment and these guys were thorough. Robert spent 3 hours explaining in detail the process by which the damage occurred, the methods to repair said damage, and the steps necessary to maintain the integrity of the basement. He then followed up with a comprehensive report a day later. Based on the quality of this initial assessment we decided to go with them and could not be happier. The work crew lead by Marvin was timely, polite and efficient. They installed an underground drainage system, repaired the wall with carbon fiber slats, and underpinned the rear portion of the house. Unlike other contractors, AA Action provides a guarantee for their work. They are also very easy to work with, prompt with paperwork, and always willing to answer questions. We strongly recommend this company for their service and quality workmanship. Thank you Robert, Marvin and Rhonda."

"We got 5 estimates from companies regarding a leak in our office and adjoining storage unit. This was the only company that accurately pinpointed the problem , which was a leak coming from gaps surrounding our electrical conduit pipe. Other companies had quoted us 6400$ to dig up the front yard and redo everything from the outside. Others wanted to dig up the inside. I’m so glad Mike explained everything to me clearly- and it all came down to common sense. These guys found the exact spot where the leak was coming from, and knew how to fix it. He also suggested replacing our sump pump because it was the original, and mud was starting to back up. He suggested we do this as it would be tragic to fix one problem and have another occur (and subsequent flooding) that could have been prevented. There was a minor connectivity issue with the sump pump a couple weeks later but I called at 9 am, the man who took the call put it in as an emergency because of some water splashing out and the problem was fixed by 11 the same day. Great responsiveness and customer service. I feel confident in my decision to choose this company, and would recommend them to others."

"I could not recommend DES enough! If you have any kids related to keeping your house, safe from water, you must talk to Mark Lane. We had four contractors assess and recommend solutions. All of them were more expensive and none gave us the confidence he did. The work was done under the time estimated and for the exact amount of the quote. Mark came three times to check on progress, and even gave us some groundcover to plant for holding the new soil in place. We recommended our neighbor have DES repair his drainage and water intrusion issue and he was extremely satisfied as well!"

"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!!"

"I called several companies to address an ongoing water problem and some told me they couldn't see me for a month, others didnt provide me with a clear understanding on what the issue was or how to correct it. When I called Brother's Waterproofing, LLC John Enciu was early and not only educated me on my water problem, he systematically when over ever aspect of the job. I have never met anyone who was so well educated in waterproofing and foundation work He is an asset to anyone who has a water problem Today marks two months since the job was done and I'm happy to say, we are BONE DRY!! Thank you John!"

"The project manager, Ms Tiffani Mercer, and her entire staff ensured all aspects of the job were on time and to specs. We were especially impressed with their hands on approach when dealing with County Inspection requirements. The workmanship was superb, professional and clean! Highly recommend and if we have the unfortunate need for other basement foundation services again, All Aspects will be the first company we will call!!"

"We had a crack in our concrete wall from top to bottom, with water leaking inside about mid-way down. We got estimates for this work but the presentation from AquaGuard convinced us they were the ones to go with. So when it came time to do the work I was totally surprised that they could come in, remove our landscaping, dig down about 8' deep and 6' wide to the foundation, repair the wall, put in a silo and sump pump, and restore it all such that you would never know anything had been done. And they did it all in one day! My wife was there and she said she was amazed at how they covered the grass with a tarp and all of the dirt being dug out was placed there so as not to disturb the yard. When I got home I expected to see a big hole and possibly a mess of my yard. As I pulled up to my house I assumed they had not come by so I walked around to the side to see what was going on and was really surprised the work had been done and everything returned to normal. Naturally it has not really rained yet for me to see if the repair has worked but when it does I'm sure, based on how professional the outside work was done and from what my wife indicated, the repair will pass with flying colors. I highly recommend AquaGuard for their professionalism and quality of work."

Foundation Repair questions, answered by experts

Yes. Foundation walls are always load-bearing.

Foundation repair uses methods such as underpinning, slab jacking, or application of hydraulic piers. Each technique is chosen based on structural needs, soil conditions, and damage extent, ensuring a stable and secure foundation.

Tree roots don’t necessarily break through concrete on their own, but they can certainly take advantage of existing cracks, even very small ones. As roots grow, they expand the cracks, making them larger and leading to serious and costly foundation damage. It’s a good idea to have repairs on any foundation cracks you’re concerned about.

If your building department catches you or a contractor doing foundation work without proper permits, they will likely put the work on hold until you secure the necessary permits, which can cause delays of days or even weeks. You can also face violation charges for construction without a permit, which can cost hundreds, depending on where you live.

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.
