Kirk Durance did a great job inspecting the backflow on my sprinkler system. He let me know what the cost would be for the inspection and the water companies fee in advance, worked with me to find a date and time that would work with my schedule, arrived a promptly, and the inspection was done quickly. In addition, he also answered my question on what he was doing and what a passing score was while he did the testing. The same day, he filed the report with WSSC and sent me a copy. I would definitely recommend him. Less

They were able to give a quick estimate, were professional and knowledgeable, arrived on time, and completed the work promptly. We knock on wood we won't have any more leaks in our house the future, but if we do we'll know who to call. Special thanks to Allan and Danny! Less

I have an older home so have needed to use Durance consistently over the years. They're reliable, professional, friendly, know their stuff, and are really, really organized. Less

We had a collapsed drain overflowing and were told we would have to punch a hole in our foundation which we had just waterproofed. We called Durance for a second opinion and Allan had a smart, creative solution that saved us great trouble and expense. All of the men who worked on our house were courteous and competent. They were quick, communicative and the job was well done. It's very nice to finally know who to call! Less

Had Durance Plumbing come out twice to fix two issues and was happy with the service provided both times - one time they changed our backflow valves that needed to be replaced and the second to flush our tankless hot water heater. In both cases, the quotes were fair/accurate and the employees who did the work were helpful and thoughtful! I also found it helpful that they offered a variety of payment options (including Venmo, cash, CC and check)! I was able to pay with CC after the services were complete and received a copy of the invoice for my records. Less

Used them for a backflow inspection and it was an easy process! Very responsive, took care of the upload to the DC site, and charged a reasonable price. Thanks! Less

Still the best in the DMV! Adam knows his stuff, other techs have come out for unrelated jobs and remarked on his fantastic work. They always go above and beyond, very responsive, not money hungry, top tier work. Wish they did more than just plumbing Less

I received a letter from WSSC indicating I needed to get a Backflow Inspection at my property. Durance Plumbing was super responsive, and professional. Walter came out and was so informative and helpful! If you need an easy to work with backflow inspection service you can trust, definitely go with Durance Plumbing! I would 10/10 recommend. Less

We're so fortunate to have Durance nearby! They're prompt, reasonable, professional, and always get it done right the first time. Our century-old house is full of quirky peculiarities but these folks bring exceptional creativity and elegant problem-solving to every recommendation and repair. Yesterday was the fifth time we've had them perform work over the last dozen years of homeownership and each experience has been a pleasure. Drop them a line! Less
