Company Overview

Dennis Diffley Drain Service is recognized as the foremost authority in residential and commercial drain services. With extensive experience, our technicians employ the latest tools and technology. Since our inception in 1976, we have been committed to the Rhode Island area.

Starting in 1976, Dennis founded the company with a simple pickup truck, a shovel, and a big dream. Dennis possessed an exceptional knack for resolving water problems. Today, with 15 committed employees, we are well-known throughout Rhode Island.

Back in 1976, Dennis and I were both out of work, seeking opportunities to support our kids. We came up with the idea to create a business that would fix broken sewer lines. We acquired the equipment we needed through rentals. When winter arrived and the ground froze, we pivoted to drain cleaning. Two determined individuals with a vision, we overcame challenges and thrived. Today, we are recognized as the go-to company for challenging plumbing tasks throughout Rhode Island.

Update: A large sinkhole has opened up above the septic tank they were supposed to collapse and fill. Unfortunately this is under a large deck that was built over that spot, putting it's structural integrity in question. Called Diffley twice. Both times told I ""was on the list."" That was a week ago.

Main drain backed up. Called Dennis Diffley & Sons and they came out within a few hours. Pulled a disgusting amount of grime and tree roots out of the line. Everything is running great now. Low and fair price. Also wore a mask the whole time which is appreciated in these times! Thank you!

They installed a new sewer line for me ,no regrets at all. They worked with me on my timeline, answers all my questions ahead to set the correct expectations and gave me a very good experience
They did professional work, completed on time at a good price with no stories I can but praise them.

I am impressed with the level of customer service and the outstanding professionalism this company displays.
I called to make an appointment for a problem we were having with water backing up in the laundry room, to my surprise they offered an appointment that afternoon at no extra charge.
The technician came out and was extremely experienced and knowledgeable. He found the issue within 10 minutes the problem was resolved within an hour.
I highly recommend this company to anyone who is looking for honesty, professionalism and integrity.

Never use this company!! They never fixed the problem, refused to get our sump pump working which they caused to stop working. They would not try to get the pump started which shut down because they jetted the lines wo taking the pumps out. All the debris from jetting the lines blocked and plugged the pump! They left a mess of water all over the floors. I called the office after they left. They never called back! We had to get an energy service the service the pump! They are horrible!

My kitchen sink wasn't draining, my plumber said the issue was in the main pipe going out to the line and I should call Diffley, they came same day and resolved the issue, I couldn't have been any happier. Great Service and Professionalism.

I get very bad experience with Dennis Diffley, I have requested to call to inform me, no call, no show. The next day, They give 10 min prior notice, I was not able to see did they do the job, their back office support was so bad, and they just don't care. Very very bad customer services. I don't know how a business with such service can still be in business.
