Services
Trenchless Sewer Repair
Our certified trenchless sewer repair specialists use cured-in-place pipe technology to fix damaged lines without excavation. This method preserves landscaping, lasts up to 50 years, and works on cast iron, clay, or PVC pipes. Ideal for property owners seeking cost-effective solutions that avoid traditional dig-up methods.
Well Pump Systems
We diagnose and repair all well pump components including pressure switches, tanks, and constant pressure systems. Our licensed technicians restore water access within hours, offering upgrades for homes with multiple bathrooms or irrigation systems. Emergency service ensures same-day water restoration.
Gas Line Services
Our master gas fitters handle leak detection, pipe replacement, and system installations with strict safety protocols. Services include backflow prevention testing and code-compliant repairs for residential and commercial properties. Available 24/7 for urgent gas emergencies.
WaterCop Installation
We install WaterCop automatic shutoff systems with wireless sensors that detect leaks and shut water flow instantly. This technology prevents property damage, conserves water, and integrates with home security systems for round-the-clock protection.
Commercial Plumbing
We provide maintenance, emergency repairs, and preventive services for commercial properties including restaurants, hotels, and government buildings. Our services include hydro-jetting, gas testing, and main sewer line repairs to minimize business disruptions.

Professional, affordable, and no nonsense - Wil did a great job! I was able to get a quote over the phone, and then the same day they were able to come out and replace the hot water heater. They even added the expansion tank, new valves, and gave me some advice on updates needed in our bathroom upstairs.
Ive spoken with several plumbers on different matters and so far this was the best experience.

Very pleased with HMS. They have done work for us at 3 different houses over the past 8 years with the most recent being a sewer relining. The crew worked long hours to get the job done over a few days. Pricing is reasonable for service plumbers. Offered financing too for the expensive relining work.

We have been using HMS Plumbing at our business, Trident Martial Arts, for over 15 years and wouldn't ever use anyone but them. They are always on time, get the job done right, and the prices are good. If you truly want a plumbing company that knows their stuff and understands what good customer service is -- call them!

Basement flooded, sub-pump stopped working, and to top it off the well was over flooded with muddy water. I called HMS Plumbing and Luis was able to arrive 2 hours later!! Luis was able to help us figure out the problems, offer lots of good advice, and installed a whole house water filter the same day. The cost of the whole visit was very affordable (A LOT less than what I thought it should cost). Luis stayed and made sure we understood everything he did and how to maintain the new filter system. Lastly, he gave us many options and ideas for what to do in the future so this kind of thing doesn
