Hidden leaks waste thousands of gallons of water a year — and the longer they go undetected, the worse the damage gets. Our San Mateo, CA leak-detection team uses acoustic listening devices, thermal imaging, and tracer-gas tools that find the source without tearing up your walls, floors, or yard.

We arrive with everything calibrated and ready in a fully-stocked truck. Most jobs are diagnosed within 60 minutes and fixed the same visit. We always quote a flat price before any work begins — never an hourly meter that ticks while we work.

Showed up two hours after I called on a Saturday morning. The tech in San Mateo, CA diagnosed a slab leak with thermal imaging in under twenty minutes, gave me a fair flat-rate quote, and had it patched by lunchtime. Five stars without hesitation.

Called four plumbers in San Mateo, CA before someone answered the phone like an adult. Rivermark was on-site by 11, quoted a fair price on a tankless water heater install, and finished the job the same afternoon. They even hauled away the old unit. Refreshingly competent.

Leak Detection FAQs

Frequently asked questions about Leak Detection

Questions we hear most often about Leak Detection in San Mateo, CA.

Talk to a real person
Are your plumbers licensed and insured?
Yes — every technician dispatched to a San Mateo, CA home is fully licensed, bonded, and insured. We carry a $2M general liability policy and worker's comp on every employee. License numbers are printed on our trucks and on every invoice.
What payment methods do you accept?
All major credit cards (Visa, Mastercard, Amex, Discover), debit cards, ACH bank transfer, Apple Pay, Google Pay, cash, and check. We also offer 0% financing for 12 months on jobs over $1,500 through our San Mateo, CA financing partner.
Can you handle commercial plumbing in San Mateo, CA?
Absolutely. We service restaurants, retail spaces, multi-tenant buildings, light industrial, and property management portfolios across San Mateo, CA. We carry the credentials required by most commercial insurance carriers and can provide certificates of insurance same-day.
What's the most common plumbing issue in San Mateo, CA?
Hard water and aging galvanized supply lines are the two biggest culprits in San Mateo, CA. We see a steady stream of water-heater scaling, low water pressure from corroded pipes, and slow drains caused by mineral buildup. A whole-home water-softener install eliminates 80% of these issues.
Why should I choose Rivermark over a national franchise?
Because we live in San Mateo, CA too. Our techs aren't bouncing between four cities — they know the building codes, the local water chemistry, and the most common pipe materials in your neighborhood. And because we're locally owned, our reputation is the business. We can't afford to do a bad job; one of us would run into you at the grocery store.
