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.

Christian came out and looked at our Shower issue. He gave us options to get the plumbing serviced. He was on time extremely professional and walked us through the process. Very high degree of professionalism.

Kameron is a ROCK STAR!!! In the past 2 weeks he has done 2 jobs on our house. The first was to bring our water heater up to code (huge shout out to Omar who did a great job too), and today he replaced our old toilet with a fancy new tankless integrated bidet. Kameron came yesterday to go over the options, he meticulously researched the toilet I selected, ensuring that we did need a boot and that the toilet would fit in our 80 year old bathroom as well as giving me a detailed, transparent quote of materials and labor. He was here first thing this morning and worked all day making everything perfect. He EVEN primed and painted the wall behind the toilet (something my husband wanted to do but was out of town). He also added caulking to the seam between our sink and the wall, which had eroded. Going “above and beyond” doesn’t begin to describe Kameron’s work, his professional service and his kindness. We have been customers of Caccia plumbing and Kameron exemplifies Caccia at its highest bar. THANK YOU!!!

Best plumber, fixes the problems! I have tried several other plumbers that couldn’t fix the problems and wasted my money. I’ve had several leaks and even if Caccia has to come back to fine tune (threads) and tighten a bit, never have s leak again. Service is on time courteous, clean and quality work.

Caccia did such an amazing job, I would definitely use them again. The technician, Pablo, was extremely communicative. We had a pretty bad water leak in our hot water heater. Pablo pinpointed the issue very quickly, kept in constant contact with me until a decision was made on the best approach, and had the repair done in less than an hour. He was kind, arrived on time, and had the water leak fixed way faster than I had imagined. Overall 10/10 service.

We are impressed with Caccia Plumbing, and always have been! They are well established and known for true expertise, professionalism, and trustworthiness! They have been around for decades! They have done both small jobs and a few larger,, more significant jobs for us. We have always been supremely satisfied. Today, Kameron and Omar did a thorough and efficient job with our shower faucet! They provided us with a few service options with transparent pricing from the basic fix it option up to a more preventative option as well aa an upgrade option for an older house. These guys were awesome and communicative, and they even fixed our side garden gate that was having a minor issue while they were in our easement dealing with our plumbing problem! What a bonus! Five stars and beyond always for Caccia! NOTE: While their prices might be slightly higher than the competition, it is well worth it! Caccia pays their plumbers and electricians very well with good benefits. This investment in their talent shows! Their employees stay with them for a long time. Kameron had been here about 5 years ago for another job, and he remembered it and even had pictures of that previous job. They also put substantial effort into quality training and apprentice programs

I don't often write reviews, but I wanted to make sure to commend the entire team at Caccia. The operations and scheduling staff is responsive, polite, proactive and thorough in keeping me up to date on scheduling. The service staff that came to my home have all been great and I want to especially call out the great and polite/respectful service I received from Nate, Pablo, and Joseph. You can't go wrong calling Caccia.

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.

For more detailed information or to schedule a service, please don’t hesitate to contact our customer service team.
