Dennis Diffley Drain Services
Company Overview
Dennis Diffley Drain Service stands as the premier provider of both residential and commercial drain solutions. Our skilled technicians bring years of expertise and utilize cutting-edge technology and tools. We have been dedicated to serving Rhode Island since 1976.
Dennis launched the business in 1976 with just an old pickup truck, a shovel, and a vision. Dennis was a natural at tackling water challenges. After 40 years, our team has grown to 15 employees, and we are recognized across RI.
Back in 1976, Dennis and I were both out of work, seeking opportunities to support our kids. We envisioned a company focused on repairing damaged sewer lines. We acquired the equipment we needed through rentals. When winter arrived and the ground froze, we pivoted to drain cleaning. Two ambitious kids with a dream, we defied the odds and succeeded. Now, we are known as the trusted choice for tough plumbing jobs across Rhode Island.

Mario R.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.
Sara B.I CANNOT say enough great things about these guys! I was pregnant and needed to relocate 2 kids into new rooms, but our basement would NOT stop flooding. they came in highly recommend so of course I expected the price to be insane. Not only were their ideas different form the 3 other quotes, (which after reviewing made way more sense) but they were not the most expensive at all. I am very happy with their work. they made a stressful situation a much calmer one. You don't want a crazy pregnant lady coming at cha! The guys were very nice, and respectful to my house. I would recommend them and also call them again, hopefully I wont have to though :)
Recently purchased house and our basement was getting wet -- but we have a French drain and two sump pumps. Should not be happening. The company we've used in the past at our old house is out of business. First, I called on a weekend. The on call person called me back in less than 30 min and did some trouble shooting over the phone. He helped me decide that it was not an emergency so we did not need to incur the $100 fee to have him come over. We could wait until Monday and get a free estimate on how to fix the problem (which we thought was two dead sump pumps). Called Monday and got an appointment for Tuesday. Technician came out (a bit a late, but that was quickly forgiven). He took the time to explain the systems in the basement -- why they were done like they were, how they could be better and why they didn't need to be changed because they work fine. He also solved the problem of the pumps...one was a power issue (battery back up was hooked to power, but pump wasn't) and one was a float issue. Since it wasn't really any work done, no charge. I can tell you I will call Diffley to make any improvements in the system should we need them or for any other services they perform that we may need. Great service.
Good experience! They were: flexible about appt. times, prompt, friendly, unclogged my drain quickly and efficiently and, with a coupon from Angie's List, charged me a competitive rate. He also suggested a product for ongoing drain maintenance. I would definitely recommend this company to unclog your drain.
Prices seemed a bit high for the quality delivered. Response was good however they were not here long for the money that was spent.
this guy tried to pay me to remove my review. Then he lied to yelp. If review does not go back up then I will go to police about his work and his attention to young girls
When I call what I think is a reputable company, I expect to have the job done properly the first time. This company sent a very inexperienced young family member to do a job at my house. It was horrendous. They did completely redo the work, however they refuse to clean up the cement spills on my driveway. I have asked them to return the driveway to its original condition and the owner refuses. She says I have cost her too much money and I am too picky. If the job was initially done correctly, they would not have had to redo it and cost this owner ""too much money"". Don't use them or be sure you watch their every move and inspect the job before they leave.
