The Practice

Ground-up estates and whole-home remodels, alongside the high-end architects and general contractors building the Peninsula. We set the underground and the rough-in, then come back for the fixtures.

See the membershipsOur Position
Since 1998 we have worked behind the doors of Pacific Heights, Atherton, and Belvedere: new construction, whole-home remodels, and the upkeep in the years between them.
Twenty craftsmen who work with the European fixture houses when a job calls for it, and who go back to the same addresses year after year. We build the water system, and then we stay with it for as long as you will have us.

Testimonials
“I will not hesitate to call them again. The communications, start time, professionalism, workmanship, courteous manner, meticulous attention to detail, and clean up, were an example to other companies and set a gold standard that I doubt can be beaten.”Chris L.
“Professional, kind, and excellent job. Nigel Mulgrew Plumbing replaced my old 100-gallon hot water heater with a high-efficiency tankless one.”Constance F.
“They were respectful, attentive and left zero mess!! The crew showed up on time and replaced the two faucets within an hour.”Loretta W.

The Standard
Behind the stone and the millwork of a great home runs copper, brass, and solder that has to hold for decades with nobody looking at it. Set a concealed valve a quarter inch too deep and the trim will not seat, and the correction is behind finished tile. That is the part of the trade we have spent our time on.
It is why the Peninsula’s high-end general contractors have kept our number for twenty-eight years.
Confidentiality
A crew is inside your home for days at a time, and they see everything in it. Our technicians are background-checked and sign employee NDAs, and we sign an NDA for your property on any project, on request. What the crew sees inside stays inside.
The Crew
We send the same craftsmen back to the same homes, so by the second visit yours is familiar: the valve, the fixtures, what is behind the plaster.
