Kahn from Master Plumbing did an excellent job on replacing my main pressure water valve. I called him around 8:30am he was at my house at 9:00am. I really appreciated his professionalism and honesty. The quote given online did not change and that made a big difference in the service. I will keep his phone number in my contact and recommend him to anybody who would need plumbing services in the future. Job well done!.
