What Our Clients Say About Our Plumbing Services in Sunnyvale?

Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.

Ron K.

Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!

Allan Huynh

CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

Sunnyvale Plumbing Frequently Asked Questions

What is the Difference Between Commercial and Residential Plumbing Services?

The plumber will then use professional tools to perform the necessary repairs, installations, or maintenance. Throughout the process, the technician will ensure minimal disruption to your home or business and maintain a clean work area. After completing the job, the plumber will test the system to ensure everything is functioning properly and provide guidance on any maintenance or follow-up needed.
