Guaranteed Plumbing Co, Danville, Ca - What are customers are saying

We just had them install a tankless water heater and a gas line for a fireplace insert. The work was very clean, professional, on time and on budget. They even removed a small shed housing the old water heater (detaching it from the house) and removed all debris.

I cannot believe there are no reviews for Guaranteed Plumbing, Having called on this company several times in the past five years, both plumbing issues and also using them for several remodels, I can personally say they are a great company. Professional, honest, genuine, top notch employees. From the owner, to the receptionist and all of the technicians, I have had very positive experience working with Guaranteed Plumbing. When they schedule an appt., they are on time and complete the work or explain what parts need to be ordered and a return visit is scheduled. They also clean up their mess, which is huge on my scale of critique. And, they are reasonable and deal with an excellent resource for their parts.
