"Atlas did a fantastic job. Mike accurately diagnosed the problem (a foundation crack hiding behind wood paneling) and patiently explained it to us new homeowners. For the repair itself, he arrived on time, applied epoxy efficiently, and dealt with some unexpected obstacles. (Some flooring needed to be removed to -literally - get to the bottom of the issue.) Our neighbor highly recommended Atlas, and we see why!"

Foundation Recovery Systems
Foundation Recovery Systems
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."
