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 relying on a store-bought DIY drain cleaner, call on our professional drain cleaning experts! Starting with a thorough inspection, we’ll address any problems with your drains, from clogs 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, and other 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.

Commercial Plumbing Repairs
Our plumbers are experts in helping your business get back to normal. We do a wide variety of commercial repair work ranging from sinks and drains to water lines. For us, there is no job too big or small.

Additionally, with the assistance of a local commercial plumbing contractor, it is possible to easily order replacement parts including faucets, fixtures, drain stoppers or even new drains entirely. Commercial plumbing also extends into thorough drain cleaning and in some cases, even water and sewer line repairs, depending on the problem that is causing issues with your commercial plumbing. Installing new pumps and pump repair is also a common commercial service we offer.

Commercial drain lines can often be a problem for a variety of reasons. Have one of our technicians come out and diagnose your property’s drain issues. If we can’t unclog your drain, no one can.
