San Mateo’s Full-Spectrum Plumbing & Electrical Service Since 1979

San Mateo’s neighborhoods range from pre-war Craftsman bungalows in Baywood and the Hayward Park area, to mid-century ranches in Hillsdale and San Mateo Park, and newer condos and townhomes near Downtown. As one of the largest cities on the Peninsula, San Mateo has an large amount of aging homes with plumbing and electrical systems that need constant attention.

Common issues we see in San Mateo include:

Pre-war and post-war San Mateo homes commonly have corroded galvanized steel supply lines and aging cast-iron drain pipes that cause low pressure, leaks, and water discoloration.
Older San Mateo homes frequently have 60- or 100-amp panels that can’t support EV chargers, heat pump water heaters, or gas-to-electric appliance conversions.
San Mateo homeowners are responsible for their sewer lateral to the city main. Clay laterals in older neighborhoods like Baywood, Hayward Park, and North Shoreview are prone to root intrusion.
San Mateo’s water from the SFPUC system via Cal Water has hardness levels that cause scale buildup in water heaters and fixtures. A water softener protects your plumbing and appliances.

What Our Customers Are Saying

Frequently Asked Questions in San Mateo

Do I need a permit for plumbing or electrical work in San Mateo?2026-04-16T22:24:08+00:00

Most work beyond basic repairs requires a permit through the City of San Mateo Building Division. We pull all necessary permits and schedule inspections on your behalf.

What causes hard water buildup in San Mateo homes?2026-04-16T22:23:33+00:00

San Mateo’s water comes from the SFPUC’s Hetch Hetchy system via Cal Water, with hardness in the moderately hard range. This causes scale in water heaters, reduces fixture performance, and shortens appliance life. A water softener helps.

My home in Baywood has old pipes. Should I repipe?2026-04-16T22:23:03+00:00

Many pre-1950s homes in Baywood, Hayward Park, and North Central still have galvanized steel pipes. Internal corrosion causes low pressure, rusty water, and recurring leaks. A full or partial repipe is usually the best long-term fix.

Who is responsible for sewer lateral repairs in San Mateo?2026-04-16T22:22:41+00:00

Homeowners are responsible for the entire sewer lateral from the house to the city main. Older clay and Orangeburg laterals are common in established San Mateo neighborhoods and are prone to root intrusion and collapse.

Does Caccia serve all San Mateo neighborhoods?2026-04-16T22:21:31+00:00

Yes. We serve all of San Mateo including Baywood, Hayward Park, Hillsdale, San Mateo Park, North Shoreview, San Mateo Village, and the surrounding areas of Burlingame, Foster City, and Belmont.

Can my electrical panel handle an EV charger or heat pump water heater?2026-04-16T22:21:00+00:00

Many older San Mateo homes have 60- or 100-amp panels that aren’t sufficient. We assess your current capacity and handle the panel upgrade and permitting if needed.
