What Our Clients are saying about Guaranteed Plumbing

Brian S.

We used Guaranteed Plumbing (and East Bay Gas Lines), Damen Nikolakakis out of Danville on a recommendation from a business associate. Very happy with the company--prompt and knowledgeable and estimate was given prior to work starting. They did the work quickly and the price I paid was the one they quoted.

A neighbor from Lafayette

We just used Guaranteed Plumbing this past week based on other recommendations on this site and found them very helpful and reasonable. They showed up early, did the work and I thought they did a great job (they ran gas & install logs). Also, got gas logs for Patio and Fireplace.

Jacob B.Customer

A neighbor from Walnut Heights

Guaranteed Plumbing (in Danville) did all of our outside work and I think they did a great job. I worked mostly with Damon and he was great start to finish.

Michael T.Customer

A neighbor from Del Amigo

…I second that - they were great and reasonably priced

Your service department did a great job at my home cleaning out the sewage line. The service tech had a great attitude, and was very patient as he looked for my cleanouts which were covered by landscaping. Due to your work we got things back to normal within the evening.

I am one of their loyal customers and have recommended their services to my friends because of the prompt and courteous service that their plumbing team provides and the high quality of workmanship I can expect every time.
