David, a great friendly pro who I was very fortunate to have to take care of the plumbing issue I had underneath the house. He replaced part of the hot water copper pipe line, that showed some corrosion and leaking, leading to the kitchen faucet. Well done in the tight crawl space. I’ll surely reach out to him again for any other plumbing issues and definitely would recommend him to others too.
Details: No, repair is not urgent • No, the building is not currently flooded • Leaking pipes • Sink • House

David worked very carefully and efficiently. Before starting, he asked couple of questions in advance, so he knows what the problem is and what to be done. After arriving he checked himself, the work turned out to be more complicated than expected. He gave me a full explanation and let me know how he is going to fix it. And he did it, within his own estimated time frame. I really appreciated his professionalism, patience, and the quality of his work. Will definitely hire him again!
Details: 1 toilet • Municipal water (most common) • House
