"I am 64 years old and have never done an online recommendation previously. I am in this instance due to their superior performance on my basement waterproofing and wall anchor project. Everyone affiliated with the company personified competence, conscientiousness and customer service. Have never had a better customer experience-could not recommend them any more highly."

"USA Waterproofing & Foundation Services did an Outstanding job on our basement!! The manager Mark was extremely professional and personable and coordinated the job with our schedule in a timely fashion. Mark sent out a qualified individual (John) to ascertain our dilemma and make the appropriate recommendation to correct the problem. The men that came to actually do the job were Awesome, they worked efficiently and did exactly what was requested in not only a timely fashion but in a proficient manner and went out of their way to come prepared and answered any additional questions we had at the time of the project. I would without reservation Highly Recommend USA Waterproofing, you will not be disappointed!! Additionally, we did quotes with three other companies and USA Waterproofing and Foundation Services had the best pricing and again, their quality of work was Excellent!! I would definitely use this company for any additional work needed at our house in the future."

"They did a quick and good job of replacing our water heater. Called again due to standing water in our yard after every rain. They came out and installed a drain and tied my downspouts into it. They also put the excess dirt against the house to improve the grading. I can say after the fall rains and the repeated freezing/thawing in winter that the drain has kept everything dry and we have had no more water issues in the basement. I would recommend these guys."

"Wyatt did an awesome job. This was a major job. I had a water pipe break just under the house foundation. They initially believed it could be reached from the outside, but determined the break was just under the foundation. Because of this, they needed to break up the concrete floor in the basement at the outside wall. They carefully removed the floor molding and the wood boards before jackhammering a 2 foot by 1 foot hole at the edge of the floor at the outside wall. They were very neat and tidy. The broken pipe was fixed in less than a day. They then cleaned out many of the faucets and came back the next day to adust the water pressure and be sure all faucets were working properly. They kept us informed at all steps of the process and the cost was less than their estimate. We highly recommend Wyatt for your plumbing needs."

Basement Waterproofing questions, answered by experts

You’ll need to reseal the foundation every five to 10 years, depending on the sealant you’ve used, the moisture conditions present in and around your home, and the condition of your foundation. Having a foundation inspection conducted before reapplication can help you catch any problems before you begin resealing. Of course, if you notice any new leaks or other moisture problems at any time, it may be necessary to reseal the foundation sooner.

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.

French drains and yard grading systems are two highly effective ways to fix standing water around the foundation. Since the French drain uses a perforated pipe covered by gravel, you won’t have to worry about water taking the soil away from your foundation. Meanwhile, yard grading levels out the ground to prevent water from gathering around your foundation.

Most houses will have vents in the crawl space. This allows for air passage and energy retention, which in many ways can help control the temperature inside the home. If you are able to consider the cost of a crawl space encapsulation, you may not need your crawl space vents at all. 

The foundation repair that will work best varies based on the extent of the damage, the underlying cause, soil conditions, weather conditions, and more. Permanent foundation solutions like underpinning and exterior drainage solutions are better than temporary fixes that don’t address the source of the issue. Some examples of more temporary solutions include mudjacking or slabjacking, waterproof paint, and dampproofing. The best course of action is to have a reliable foundation specialist inspect your issue, treat the underlying problem, and restabilize your foundation.
