Serving Sunnyvale since 1979

Expert Plumbers & Electricians in Sunnyvale, CA

Nearly all of Sunnyvale’s single-family housing is slab on grade, so supply and waste lines run under concrete instead of an accessible crawlspace. Locating a leak precisely matters here, and that is where we start.

Sunnyvale, CA

Sunnyvale’s Full-Spectrum Plumbing & Electrical Service Since 1979

Ponderosa Park, Cherry Chase and Birdland are 1950s ranch homes, the Heritage District holds the oldest stock in the city, and newer apartments have gone up downtown. Nearly the whole city was built after 1950, which keeps the housing more uniform than most of our service area.

What our Sunnyvale customers are saying

They were really easy to schedule with and we were able to complete the entire plumbing and electrical project from estimate to finished product in 1 day. Their pricing is more than fair and both technicians were really friendly and great at explaining the scope of work.

What Our Customers Are Saying

Frequently Asked Questions in Sunnyvale

Do I need a permit for plumbing or electrical work in Sunnyvale?2026-04-16T22:57:17+00:00

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

Why are slab leaks common in Sunnyvale?2026-04-16T22:56:42+00:00

Many Sunnyvale homes, particularly Eichlers and mid-century ranches, are built on concrete slabs with copper pipes running underneath. After 60+ years, soil movement and corrosion cause pinhole leaks beneath the slab. We use electronic detection to locate them precisely.

My home in Cherry Chase has old plumbing. Should I repipe?2026-04-16T22:56:05+00:00

Eichler and mid-century homes in Cherry Chase, Lakewood Village, and similar Sunnyvale neighborhoods are known for aging plumbing. After 60+ years, pinhole leaks and corroded joints are common. A full repipe with modern materials is typically the best investment.

Who is responsible for sewer lateral repairs in Sunnyvale?2026-04-16T22:55:14+00:00

Homeowners are responsible for the sewer lateral from the house to the city main. Older Sunnyvale neighborhoods commonly have clay sewer laterals that are vulnerable to root intrusion and settling.

Does Caccia serve all of Sunnyvale?2026-04-16T22:53:53+00:00

Yes. We serve all Sunnyvale neighborhoods including Cherry Chase, Lakewood Village, Ponderosa Park, Downtown Sunnyvale, and the surrounding areas of Mountain View, Cupertino, and Santa Clara.

Can my electrical panel handle an EV charger or heat pump water heater?2026-04-16T22:53:23+00:00

Many mid-century Sunnyvale homes have 100-amp panels that aren’t sufficient for today’s electrical loads. We assess your current capacity and handle the panel upgrade and all permitting if needed.
