I had a leak in my shower and wanted to replace the shower head anyway. Company other than Craig Plumbing came out to change out shower head, but leak persisted. I called Craig. He was out promptly. He discovered that the water pressure was much too high in the house and that the pressure regulator was failing. So he fixed the cartridge in the shower. The next day he replaced the pressure regulator. Craig is extremely professional. He keeps you updated on timelines, explains what he is doing without a lot of jargon and charges fair prices. Highly recommend!
