San Carlos Plumbers

Full-Service Plumbing for Homeowners & Business Owners

Plumbing Plus has been serving San Mateo County homeowners and property managers since 1984. That's over 40 years under the same brand, built on one straightforward commitment: reliable plumbers, quality work, on time, at a fair price. Founded by Joe Christenson as a retail plumbing store in Poway, the company grew into a full-service operation handling everything from drain cleaning and water filtration to repiping and complete fixture work. Michael De Silva joined the team in 2001 at age 19, trained under experienced professionals, and worked his way up to lead plumber before he and his wife, Rachael, took ownership in May 2010. That continuity matters. We aren't a national franchise or a company that changed hands and reset its history. We're a family-owned business that has earned its reputation one customer at a time.

San Carlos sits at the heart of the mid-Peninsula, a community of established single-family homes that often need repiping, fixture upgrades, and drain maintenance. We serve both residential homeowners and commercial and property management clients across the area. Whether it's a water heater failing on a Sunday morning or a slow drain that's been ignored too long, our red, white, and blue trucks are ready to respond.

When you're ready to schedule or need a plumber now, call us at (858) 630-3141. We offer free, written estimates and 24/7 emergency service, no matter the hour.

What San Carlos Residents Can Expect From Every Visit

Before we touch anything in your home, you'll receive a free, written estimate that details exactly what the job requires and what it will cost. No surprises, no hidden fees. Our pricing reflects the scope of the work, nothing more. Once a technician is on the way, you'll receive an automated text 30 minutes before arrival with information about who's coming. After the job is done, your technician collects payment by tablet and immediately sends photos of the completed work along with your invoice. That level of accountability isn't common in the trades, and we think it should be.

Every plumber we dispatch is screened and background-checked, arrives in uniform, and is trained to treat your property with care. We're also a member of the Plumbing Heating Cooling Contractors Association (PHCC), and our work has been recognized by the Angi Super Service Award, Neighborhood Favorites, Expertise, and Best of HomeAdvisor. We back every job with warranties on both workmanship and materials, and if you're not completely satisfied with the result, we'll make it right.

The Plumb Star Partner™ Membership Program

For San Carlos homeowners who want priority access and year-round peace of mind, our Plumb Star Partner™ membership delivers a level of service that standard customers don't get. 

Plumb Star Partner™ benefits include:

• Front-of-line priority scheduling for routine and emergency calls
• 10% off all plumbing services
• No dispatch fees
• Free estimates on every job
• Annual safety inspection with a water quality test, water pressure check, leak inspection, dye testing of toilets, water meter check, water heater flush, and a sewer camera inspection of one drain
• A one-year workmanship and materials warranty on all work completed while the plan is active

That annual inspection alone covers the kinds of issues that aging Peninsula homes tend to develop quietly: mineral buildup, pressure irregularities, and early-stage leaks before they become costly emergencies. Combined with priority scheduling and discounted service rates, the membership is built for homeowners who want a plumber they can count on before something goes wrong, not just after.

Financing for Repairs That Can't Wait

Unexpected plumbing work doesn't always line up with the budget. Through our partnership with Service Finance, we offer flexible financing plans: short-term options with low interest or longer term plans with lower monthly payments. This helps a necessary repair or upgrade avoid sitting on the back burner.
