I am a local general contractor that focuses mostly on remodels and additions… I have had Matt at Golden State Plumbing do a few projects for me over the years and would highly recommend him and his crew… He communicates well and is there when he says he’s gonna be there… and does great work…

Matt at Golden State Plumbing has helped us with several jobs this year and the experiences have been consistently outstanding. He is professional, fair in price, respectful of our home and it’s clear he is experienced with what he does. He just recently helped us with switching old copper pipes out from our well to our main water line and a second home on our property. He found several leaks and took care of them for us.

We have called Golden State Plumbing and Drain for several plumbing jobs in and around our home. From major pipe repairs to installing a water softener underneath our kitchen sink and a Moen leak detector. Matt and his team does excellent and efficient work. He is highly experienced and qualified to repair any plumbing issues we may have. I highly recommend his services. Bill and April

I sent Matt down to my dark, damp, sloped basement, and was blown away by how well he got all our leaks – both obvious and hidden – fixed in a timely manner. I have had them out a couple of times as they’re now our no-pressure, easy to work with go-to plumbing service.

Expert Residential Drain Cleaning Services

Has your toilet, shower, or kitchen sink begun to drain too slowly? Hair, toilet paper, grease, and personal grooming products can cause your drains to back up, leading to unpleasant smells and potentially long-term plumbing damage. Instead of using caustic store-bought drain chemicals, call our professional drain cleaning experts! Starting with a thorough inspection, we’ll address any problems with your drains, from clogs & debris to parts repairs.

Innovative and Effective Sewer Line Cleaning

At Golden State Plumbing, we’ve seen how other plumbers work. Because we weren’t happy with the industry standard for sewer line cleaning, we created our own more effective technique! Using this “progressive rodding” method, we’ll open a hole in your in your pipe and then use progressively larger rods to completely remove built-up minerals, debris, tree roots, and other serious clogs.

Keep Your Home’s Water Flowing by Repiping

If your home is several decades old, it may be time to consider repiping with copper or PEX . Even if you haven’t noticed the tell-tale signs of malfunctioning pipes (like leaks, flakes, or rusty water), there may be damage hidden inside your walls. By turning to our expert repipe services, you can rest assured that your pipes are in mint condition and safe from costly damage and unhealthy contaminants.
