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.

Trust Your Sump Pump to Our Licensed Grass Valley Plumbers
