Let�s make your basement or Crawl space dry, We have been servicing Illinois since 1979 and pride ourselves on the quality of work that we provide to our homeowners.

"My basement has always leaked and was never dry. I called Donnie Felton, who was highly recommended by a few friends, he was very knowledgeable and explained exactly what he would do step by step. He showed up the following week and completed the job in two days. My basement is now dry and does not see a drop of water even during the heaviest rain. I love not seeing any water in my basement. I would highly recommend Donnie Felton."

Foundation Recovery Systems, founded in 1992, is a subsidiary of Groundworks, a family of companies that offers superior, proven solutions for your foundation repair, structural repair, crawl space encapsulation, dehumidification, and concrete leveling needs. They currently maintain offices in Kansas City, Moberly, Springfield, and St Louis. Foundation Recovery Systems is a recognized accredited member of the Better Business Bureau and devotes its years of experience, industry knowledge and specialized training to help customers protect their homes or commercial buildings from water damage, concrete sinking, and foundation failure.

"As far as we can tell, the work was effective at stabilizing our foundation, and the on-site crew led by Luke was great, informing us of their progress along the way. However, we expressed in advance our concern about protecting some of our landscaping. We were assured the crew would have boards to cover landscaping on which removed dirt would be piled. This turned out not to be the case. I’ve had quite a bit of expense and labor to restore landscaping that was damaged during the work. This damage could have been avoided. Foundation Recovery sends out $500 coupons to advertise for their work. My attempts to contact Joe and FRS to honor even a part of the $500 coupon to help defray my landscaping costs have gone unanswered. Our salesperson, Joe, was not present during the work and has not been responsive to our followup inquiries. We are very disappointed in the poor customer service from Foundation and its representatives. I cannot recommend this company based on their failure to address our up-front concerns, lack of response to our followup requests, and the false advertising that is associated with the coupons."

Basement Waterproofing questions, answered by experts

Although the two terms are closely related and often used interchangeably, pier and beam foundations and crawl spaces are different things. A pier and beam foundation is made up of concrete piers and wooden beams and creates a space under the home known as a crawl space. There are several types of foundations that create crawl spaces, often collectively known as “crawl space foundations,” but the crawl space itself is separate from the foundation. 

Plan on cleaning your crawl space at least once a year, though twice a year is ideal. During the cleaning, remove any debris or dust and check for potential issues like pest infestations or water damage. The sooner you catch these issues, the easier (and cheaper) it will be to fix them.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

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. 

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.
