"Our house had a partially missing footer because the company who installed our deck removed the footer to install a footer for the deck but failed to repair the footer for the house. There was a crack in the foundation wall as well. The repair included repairing the footer and placing piers to support the footer. And jacking the wall in order to close the crack. Santos Cruz and Anthony Frock did an excellent job explaining the process and executing the repair. Both were professional and courteous."

"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."

"Jason was excellent and I will absolutely use AA Action Waterproofing for future projects. After having two other companies provide estimates for fixing our basement leak problem, I called AA Action for a third quote. The first two companies recommended extensive indoor and outdoor remedies with expensive price tags. I was a bit surprised because our leak is very minor. Enter Jason. Jason was friendly and clearly had extensive experience. He assessed the problem and pointed out that, while we could of course undertake the considerable actions the other companies recommended, it was more than likely that a simple fix of rerouting our gutter drain would fix our problem - a $20 fix that we could do on our own vs. the thousands of dollars in repairs recommended by the other companies. He told us that he could not honestly take our money knowing this small fix was likely all that was required. The remedy worked. It's rare to find Jason's honesty in the home contracting world; I will definitely call AA Action for any future issues."

"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!!"

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"I hired Humberto and company to do some work to my back walk-up; including structure repair, adding a step, burying a pipe for the sump pump and adding some height from the front step plus a railing. Adding waterproofing and concrete surface protection. Humberto carefully explained every suggestion. Always communicated any delay due to weather. He immediately and completely answered questions and concerns. The sub-contractors hired were also professional, punctual, hardworking. Not only on time, but the project was also completed early beyond expectations."

"I had spoken to several contractors, Mr. Matthews took the time to explain the entire process of what was needed and why this option would be better than the prior. He was the ONLY contractor to show me his license and make me feel comfortable with all he explained and made sure I understood all that was needed. I appreciate all the time he gave me and the great work his crew did to get my foundation fixed and drainage issue fixed!! Thanks! Sara"

"I had a great experience with Guardian. The team was on time, hard working, polite, and left the house spotless. They repaired the drywall they needed to cut into and showed me all of the work as it progressed. The work also came with a lifetime guarantee. I would definitely recommend this company.

Foundation Repair FAQs, answered by experts

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. 

Ensures structural stability and long-term safety of the building.

Concrete spalling can be fairly serious, especially if left untreated or in a public area. It can be a tripping hazard and, if not resolved, can lead to structural instability.

The best solution to fix a foundation crack in your basement floor depends on the underlying cause. If you just have hairline cracks from settlements that are no longer growing, the best option is to seal them with a crack sealant. If the cracks continue to grow, one edge rises above the other, or there are signs that water is getting in through the crack, a professional repair will be necessary. Depending on the root cause, your professional may employ foundation underpinning or some other type of stabilization, seal the cracks, or install a drainage system.

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