Our expert technicians handle all plumbing emergencies and routine repairs with precision. From leak detection to fixture replacement, we use advanced diagnostic tools and high-quality materials to ensure lasting solutions. Our team completes repairs efficiently while maintaining clean workspaces and providing clear explanations of all work performed.
Trenchless Pipe Relining
Nuflow trenchless technology allows us to repair damaged pipes without excavation. This minimally invasive method preserves landscapes and structures while creating durable, seamless pipe linings. Ideal for hard-to-reach areas, this solution reduces repair time by up to 50% compared to traditional pipe replacement methods.

We clear stubborn drain blockages using hydro jetting and mechanical snaking equipment. Our technicians identify root causes of recurring clogs and implement preventive solutions. Commercial clients benefit from scheduled maintenance programs that prevent costly downtime from drainage issues.
Water Heater Service
From routine maintenance to complete system replacement, we service all water heater types including solar-powered models. Our technicians diagnose efficiency issues and recommend cost-effective solutions that ensure reliable hot water supply while optimizing energy consumption.

Report
Mom's plumbing was old and deteriorating. 535 Plumbing came in and did a super job installing a new water heater and repiping her home. She is extremely happy with the increased water pressure, super hot water, and clean and clear water.
535 Plumbing inspected the property, provided options to fix the problems, and provided a reasonable estimate. After comparing them with other plumbing companies, we selected 535 Plumbing and we're extremely satisfied with their service. They completed the work as promised, in a timely manner, and stuck to the estimate provided even though there

Called 535 for a leaky toilet and a dripping shower faucet. Scheduled at 9am. Puni, the service technician came in at 9am. ON TIME! Awesome! Not only did Puni do a great job fixing the problems but he is just a nice and pleasant guy. Top notch customer service, punctual, hardworking technicIan and fair pricing. I really cannot ask for more. I will definitely do business with them next time I have plumbing issues. Shane M. You should be proud to have such a great group of people working for you.

Overwhelming, that's how I can best describe my experience with 2 other plumbing companies we've spoken to. We own an old home with a lot of issues, one of them being the plumbing. The first company we spoke to understood what we wanted done, but didn't really take in to consideration what we could afford. Another company sent a representative that wanted to pile on a bunch of stuff on top of what we were already asking. That rep literally walked around our house saying "we can do that" to every little thing he saw. I was beginning to think he

It took me awhile to do this review of the water line installation for my newly purchased refrigerator. Called them after seeing their TV commercial one evening
They didn't do a site inspection but ask me to send pictures instead for the scope of the work needed. Original plan was to run the line from the sink water line to the opposite wall, through the cabinets and behind the range. Owner said going behind the range was usual but I had my doubts because it is a drop in range and not a slide in. Fortunately when the two plumbers came the next day, We came up with an alternative that worked
