Services
Drain Cleaning
Our drain cleaning specialists use advanced equipment to remove clogs and buildup from residential and commercial plumbing systems. We employ hydro jetting technology to thoroughly clean pipes, prevent future blockages, and restore optimal water flow. This service helps maintain sanitary conditions while extending the lifespan of your plumbing infrastructure through comprehensive maintenance solutions.
Sewer Line Repair
We provide complete sewer line diagnostics and repair services using trenchless technology and traditional excavation methods. Our technicians locate leaks, cracks, and root intrusions through video inspections, then implement durable repairs that meet local code requirements. Emergency sewer backups receive priority scheduling to minimize property damage and health hazards.
Water Heater Installation
Our team installs and maintains conventional tank and tankless water heating systems for residential and commercial properties. We help clients select energy-efficient models that match their hot water demands while ensuring proper installation for safety and performance. Regular maintenance services extend equipment lifespan and maintain manufacturer warranties.
Leak Detection
Using thermal imaging and acoustic listening devices, we identify hidden water leaks in walls, foundations, and underground lines. Our non-invasive detection methods minimize property damage during diagnosis, allowing precise repairs that prevent water waste and structural damage. We provide detailed reports showing leak locations and recommended repair strategies.
Gas Line Installation
We install and service natural gas and propane lines for residential and commercial applications. Our licensed technicians handle appliance hookups, system expansions, and safety inspections while following strict safety protocols. All installations meet local building codes and include pressure testing to ensure leak-free operation for heating systems and appliances.

Love these guys. Dave and his crew are great and their prices are great. I've had them clear drains, re-pipe old houses and even do the small jobs others wouldn't. I recommend these guys for all your plumbing needs.

Dun Well Plumbing has done well for me! I have had two emergency plumbing needs in the last 6 months. 1st, a couple months ago, my water heater had a blow out and spilled water all over. I was at work and wasn't able to take care of it. I called Dun Well and Dave took great care of me. He came out with a new water heater and replaced the old one on the same day! Awesome response! Then just yesterday I had a clog in my kitchen sink line. Water was totally backed up and not draining at all. Dave came out once again at a moments notice and worked very hard to snake my drain. He was very persistent

BEST IN CLASS - I own 80 apartments and trust all my plumbing work to Dave and the Dunwell team. They are super responsive, fairly priced and can fix complex problems they many full service plumbers won't touch. Dun well has the best snakes and equipment in their trucks of many plumbers I have used which usually means the job gets done fast in fewer hours which equals less cost to me. Bravo to Dave and Dun Well. They are simply the best.

I've had them out for services over the past 5 - 6 years, and am very pleased with them. They've always been out when promised, work done properly ( never had to return ) and priced fairly. Technicians have been polite, clean, and neat. I highly recommend you consider them, I'm sure you'll be happy as well!

This is the first time using Dun-Well Plumbing. They tackled a large job replacing sewer lines under a large 47 unit commercial/residential complex. Extremely professional and highly concerned with the water needs of the commercial unit's customers as well as the residential tenants while they worked. The project headed by David was almost painless as far as the inconvenience to tenants.The price was fair and the workers did an excellent job cleaning up. Would highly recommend David and Dun-Well for any project large or small.

I used to work for a plumbing company for 11 years with my husband. Now I have to rely on calling out of the phone book. I have to say nothing but honest service. I had another plumbing company come over and tell me I needed a new sewer line that would cost $8,000. So I decided to get a second quote, and Dave came out and said I only needed to fix the section that was broke, which ended up being the washer line...REALLY!!!! Cost me $650.00 and they were out in 4 hours. They even put chemicals down to get rid of the smell. They came within a few hours. I knew that it didn't seem right, and
