i was initially very impressed with their sales pitch and concept they preached. I had gotten bids and they recommended areas that the other company had not. I have had to call then back twice and am getting ready for a 3rd time. They raised an area that did not have a problem, and this has caused my ceramic to crack. I have gotten several professional opinions placing the blame on WCK, but they are not willing to accept any of the blame. Since I have the same tile throughout my house, and it is discontinues, it will cost me a fortune to replace. The initial area that I wanted repaired is as bad or worse than before, and is delaying me in painting my exterior. Even though cable lock was initilly more expensive, I wish that I had chosen them as other family members did (with no problems) a it would have been much cheaper in the lone run.
