Get matched with top basement waterproofing pros in Grandview, MO

"KC Waterproofing Jim Williams reviewed our property, found our problem, gave several suggestions that we could do to help drainage. Then Connor came out repaired our crack and we are good to go! Iâ m and Connor were very professional and solved our problem. I highly recommend KC Waterproofing!"

"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."

"They called as soon as I searched for a pro and coincidentally, they’re the same pro our friends referred to us as they also got their plumbing services when they bought a home. We didn’t have to wait for a week or so, they made it possible to have the job completed before we left (we were just visiting from Vegas to help our son moved to his new home). Everything went flawless, Trey went above and beyond. He noted other issues that need to be taken care of and he finished it in a timely manner, no hiccups thank God."

"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."

"overall good. All these guys worked very hard to get it done. When hiring a waterproofing company to waterproof a basement I would expect the company to fix any water issues coming into the basement that was uncovered during the process. When we tore sheetrock off the basement wall in one corner we seen a water issue letting water to come in to the bedroom. One guy told us that it was above his pay grade. We had to go thru 2 different handymen before we got it resolved. Again you all advertise waterproofing basements with a lifetime warranty. Other than that your people worked hard to complete our job so please let them know. Thanks."

"Explained exactly what they would do and the condition they would leave the area in. Weâ re good for their word. Very heavy rain just three days afterward and everything held. No water in basement since they did their work and itâ s been 9 months."

"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."

"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."
