My experience with JNK waterproofing was horrible. They came to quote the retaining wall job and came in at a reasonable price. They also agreed to regrade and pour a new concrete walkway by the garage. The retaining wall - they didnt dig a trench, put any water barrier or weeping tile. They put in one row of cinderblock and told me it would cost more if I wanted another row. They filled the first row with concrete, spilled concrete all over my plants and left garbage in my back yard. The walkway - they didnt dig up the old concrete and poured on top of the old. They splashed concrete all over my house and my neighbours car. They refused to finish the job until I paid in full. (I had already paid all but $500 of the job). I refused to pay in full until the job was complete and they cleaned up. They left and never came back. No relief cuts in the concrete. They removed and didnt rehang they gate to my backyard. They didnt clean up their mess. Absolutely the WORST contractor I have ever hired.
