"Had a pipe break and flood a section of our finished basement. Kevin with Anthony showed up diagnosed the problem and then recommended a drying company. He called them and they showed right up. Seamless process."

"Thrasher did a good job on the basement foundation and installation of new sump pump. A little pricey. Workers were prompt, courteous and cleaned up when done."

"Dave from Foundation Recovery came and did my annual basement inspection. I’ve had a sump pump - and gutters to direct the water to it - installed by them, for three years. And so far I’ve had no water in my basement. Even during the heavy spring rains in KC. Dave was very friendly and professional, and very knowledgeable about basements and their problems. He answered all my questions to my satisfaction. I appreciate the great service Dave! Thanks."

"This is a great company to use in making a 141 year old basement waterproof. I look foreward to having a waterproo basemant. Craig was pleasant and went the extra mile to make the experience great."

"The installation went well. Since it was done because of water leaking in my basement, there were some issues after a major rain storm. The owner came out per my request and agreed to come back to readdress one area that still needs repair after another big rainstorm in the future."

"Service technician attempted to auger main sewer line with powerful, large auger which he had to transport down basement steps. He was able to clear line up to point where it left house but encountered snag and was unable to retrieve auger. He then televised line and showed me a large mass of tree roots that was blocking sewer line and where the auger was stuck. It took him quite a bit of time and difficulty to free auger. He then informed me that the concrete floor in the corner of the basement would have to be cut out around a clean-out since it was impossible to clear the snag with the auger. He also informed me his company could perform that service but not him since it required a plumber. He called in the request for an estimate in my presence but no one ever called to schedule the work. So I hired another plumber who dug out the floor and found the snag exactly where the technician said it was. Even when the clean-out was removed, the plumber had a difficult time clearing the roots and said that no auger could have cleared it. So I am very happy with the services of this company even though they failed to follow-up with an estimate for the additional work."
