David came to help us install some drip lines to water pots around the garden. We found a very big leak, under the boulders that were cemented together. It was an impossible place to fix but David and Hector did not give up. They got the boulder out and did as little damage as possible to fix the leak. Had to cut a root but that was the worst of it. Most people would have walked away from the job but they don't quit. I was so impressed with the knowledge, skill and tenacity. We will definitely be using them again. read more
