Knob Hill installed a reatining wall for me, and every year in the Spring, it sags and gaps between due to the ground freezing and thawing. I'm tired of having the same issue every year, and wasting theirs and my time fixing the same problem over and over. Instead of fixing it ""correctly"" once by motoring the joints, they continue to ""dry stack"" the bricks and every year we have the same problem. This year I contacted them in late Feb and they came to house to investigate the problem in mid-March. Since then they have not retunred any of the 12-15 phone calls I have made. This is extremely unprofessional and frustrating from a customer who just wants the product they bought to be right, since it was never installed correctly to begin with.
