Foster City, CA

Foster City’s Trusted Plumbing & Electrical Service Since 1979

Sea Colony and Marlin Cove date to the 1970s build-out, Isle Cove and Edgewater Isle add townhomes and condominiums along the water, and newer construction has taken the remaining parcels. Nearly all of it sits on the same engineered fill, which is the common thread through the plumbing here.

What our Foster City customers are saying

Jaime replaced the valves in both bathrooms and the kitchen sink, as well as the shower faucets and trim, while Hector replaced the toilet… Even though there was a lot of work to complete in one day, they finished everything on time and did the job neatly and efficiently.

What Our Customers Are Saying

Frequently Asked Questions in Foster City

Do I need a permit for plumbing or electrical work in Foster City?2026-04-16T19:23:37+00:00

Yes. Foster City requires permits for most plumbing and electrical work beyond minor repairs, issued through the city’s Building Division. We handle all permitting and inspections on your behalf.

Why do Foster City homes have similar plumbing issues?2026-04-16T19:23:00+00:00

Because Foster City was built almost entirely between the 1960s and 1970s, most homes have plumbing systems that are now 50-60 years old. Pipes, water heaters, and sewer laterals all reach the end of their useful life around the same time.

Are Foster City homes at risk for slab leaks?2026-04-16T19:22:26+00:00

Many Foster City homes are built on concrete slabs with copper supply lines running underneath. After 50+ years, soil movement and copper corrosion can cause slab leaks. We use electronic leak detection to locate them quickly.

Who is responsible for sewer lateral repairs in Foster City?2026-04-16T19:21:54+00:00

Homeowners are responsible for the sewer lateral from the house to the city main. Foster City’s fill-based soil conditions can cause lateral settling and joint failure, even in relatively newer pipe materials.

Does Caccia serve all of Foster City?2026-04-16T19:21:17+00:00

Yes. We serve all Foster City neighborhoods including the lagoon-side homes, Bay Meadows, Flying Carpet, and the surrounding areas of San Mateo and Belmont.

Can my electrical panel handle an EV charger or heat pump water heater?2026-04-16T19:20:41+00:00

Many Foster City homes have 100-amp panels original to the home. These are often insufficient for modern electrical loads. We assess your current capacity and handle the panel upgrade and permitting if needed.
