After paying Joe in full at his request for installing an irrigation system, we didn't see or hear from him for 3 weeks. When he did finally show, he asked for additional money before the job was finished and we declined, he in turn,did not finish the job, and will not return our calls. We had other estimates at the same amount as Joe's, but we chose him to do the job. He had worked for us before with no problems. Very disappointing, we had to hire another contractor to finish his work at additional costs. Don't pay him upfront and get his quote in writing!!!
