What neighbors say about working with us
“I have worked with Simeone for years now, and they are amazing. Their plumbers, their office, and their ownership have been nothing but responsive and helpful and always make us a priority. Wouldn't use anyone else!!!”
“Amazing people! They really saved my butt on this one. They were able to quickly come out and line a pipe. Very professional. Did an amazing job. Gina and Dominic are fantastic. Cannot recommend them enough.”
“We recently had Simeone Plumbing replace our aging 75-gallon water heater, recirculating pump and leak detector. They responded quickly to our inquiry and Domenic himself came out to review the project and discuss options. …”
Our story
How we came to be
It started in high school
Domenic Simeone found his trade early, plumbing high-end homes in a new development in Sonoma while still in high school. He took pride in getting every detail just right, and that dedication carried him up through the trade.
From new construction to service
After years in new-home construction, Domenic worked with three of Sonoma County's most respected plumbing firms. There he learned what homeowners actually need when something goes wrong: trust, straight answers, and reliable service.
Simeone Plumbing is born
With Gina's support, Domenic started Simeone Plumbing in 2007 with a simple aim: honest, quality care, the kind we'd want in our own homes. Today Domenic, Gina and our team bring that same care to every job across Sonoma County.
