What Plumbing Service Covers
Most of the plumbing that goes wrong in a Bay Area home sits in the mechanical room, right beside the heating system: the water heater, the gas line feeding it, the hydronic loop under a radiant floor, the condensate drain off a furnace or heat pump. Sending two separate trades to look at one room wastes a day and usually ends with each pointing at the other.
We cover that overlap directly — water heaters of every type, hydronic and radiant circuits, combi boilers, and the gas, water and condensate connections our own equipment depends on. Drain and sewer work, repiping and fixture replacement belong to a licensed plumbing contractor, and we say so rather than take the job.

Water Heaters
Tank, tankless and heat pump, sized to the fixtures actually running at once rather than to whatever came out. We quote the like‑for‑like replacement against the efficient option so the choice is about the house, not about what is on the truck.

Hydronic & Radiant Heating
A cold zone in a radiant floor is almost never the floor. It is a zone valve, an air‑locked loop or a circulator, and finding out which one costs a diagnostic rather than a demolition.
- Zone valve and circulator diagnosis
- Air-locked and unbalanced loops
- Combi boiler installation and service
- Radiant floor repair from $199

- Gas line sizing and appliance hookups
- Leak checks and pressure testing
- Condensate routing and drain work

Frequently Asked Questions
The mechanical side: water heaters of every type, combi boilers, hydronic and radiant heating circuits, and the gas, water and condensate connections that heating and cooling equipment depends on. Our licence is C‑20 — HVAC — so drain and sewer work, repiping and fixture replacement go to a C‑36 plumbing contractor instead, and we will tell you that rather than take the job.
Water heater installation starts from $2,200, heat pump water heaters from $5,500, ductless high‑efficiency combi boiler and water heater installation from $7,000, and radiant floor heating repair from $199. Every visit is quoted itemized and upfront before work begins.
Shut off the water supply to the unit, and the gas or power if it is safe to reach, then call us. A leaking tank almost always means the tank itself has failed and needs replacement rather than repair.
Yes. A single cold zone usually points to a failed zone valve, an air‑locked loop or a circulator problem rather than the floor itself. We diagnose the circuit before proposing any work that involves opening the floor.
Yes, for the connection serving the equipment we install, including sizing, leak checks and permitting where the jurisdiction requires it. Whole‑house gas repiping is outside our scope.
Yes. We work with property managers and building owners across the Bay Area on water heater replacement and hydronic circulation problems, and can schedule around tenant and operating hours.
