Residential Plumbing Services

Residential Plumbers Grass Valley

If your home’s toilets, pipes, showers, or other plumbing fixtures are in need of service, you need the most reliable residential plumbers: Golden State Plumbing! For over 10 years, we’ve brought our unmatched expertise to households throughout Grass Valley, Nevada City, and Auburn, offering professional services at every stage of the process. From initial inspection and diagnosis to spot repairs and full system replacements, nothing is beyond the scope of our residential plumbing pros.

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.

Trust Your Sump Pump to Our Licensed Grass Valley Plumbers

Sump pumps are an absolutely essential aspect of your home, keeping your basement dry and protected from major issues like water damage, mold, and rot. Our residential plumbing company has expertise in every aspect of sump service.

If you suspect an issue, call us right away for timely, professional, and courteous plumbing services!

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. Commercial plumbing services vary depending on your needs and can range from simple repairs of hot water boilers and commercial water heaters to working with the pipes and drains themselves if they are clogged or dysfunctional. 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.

Drain Cleaning

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. We offer a variety of drain cleaning services including jetting, cabling, and snaking. Give us a call to fix your clogged drain today!

Backflow Services

Backflow preventer devices are an essential part of your plumbing and water supply system. If you have a failed backflow inspection or want to get a new backflow installed, we can make the whole process pain free. 

Commercial and Industrial Water Heaters

If your business is in need of an experienced water heater provider then look no further.
