Plumbing Services In Sterling, Alexandria & Reston, VA

“ Had a leak in our master bathroom after only a month in our new house. I couldn't pinpoint the source and rather than risk significant water damage in the living room below, I called Cardinal Plumbing and they sent out Carlos on a Saturday morning. Carlos was quick, worked clean, found the problem and even recommended an economical contractor for drywall repair since Cardinal doesn't do sheet rock. Carlos was personable and made the repair seem less burdensome. Great reasonable price for the visit too. I have definitely found my go to plumbing company for the new property!” Jon

“ Love cardinal plumbing. Great service by Danny and George. Have been using them for years and always very responsive and great work!” Michelle

“ They were responsive to a holiday weekend call and came to the house promptly. Carlos explained everything to me clearly and he did a great job with our finicky faucets. I would definitely use them again.” Kathryn

“ Had our main sewer line back up raw sewage into our basement on Memorial Day (of course it happens on a holiday.) Called a few companies with no response or the response that they had no one available before I found Cardinal. Chris came out and ran about 130' of snake through our main line before he found the clog and the water started flowing freely. He then ran a camera through to ensure he got it all, and advised us on the potential cause and what we may want to watch out for in the future. He was incredibly professional and explained everything to us throughout the process. He even mopped up the floor when he was done. I felt the fee was more than reasonable for the service performed, especially on a holiday. I would not hesitate to call Cardinal for any future plumbing needs. A+” Kurt

“ We just moved and we bought a house from a couple of DIY idiots lol! Anyway, Carlos came out and found not one, but TWO leaks. Cool. He explained everything and was really fair in pricing. Okay fast forward 2 days later..leak on the bathroom floor again. Well, Carlos came out the next day and found another 2 leaks. Just further up the wall. It was hard to diagnose because it was in a guest shower that's barely ever used. Well he found that they used a piece of grocery plastic bag instead of Teflon tape on one of the pipes. At this point, you have to laugh. Anyway, the point is that even though the previous owners were idiots, we are thankful we found a great plumber that found the issues very quickly and did NOT overcharge. Highly recommend!” Amber

“ Mark K. was extremely professional, helpful, and is very good at his job. He completed everything very efficiently and was open to answering all of our questions. We truly appreciated his conscientiousness, especially since he was working into the evening. He reset a toilet, fixed it from running and removed a toilet and installed a new one in a different bathroom. I would recommend him and Cardinal Plumbing to anyone needing help.” Jan

“ It was very easy to get an appointment to get and estimate and then a following appointment to get the mixers replaced in both my bathrooms. George gave me estimates on both fixing the existing old mixer and replacing them. He recommended which company mixer I should go with. On the day of appointment he told me how much time it would take to complete the work and he did a fantastic job.” Aparna

“ This company was recommended by a friend. I was scheduled between 2 and 4 pm and the plumber was here at 2:30. Inspected the job and gave me a flat rate for fixing the two outdoor faucets. One required replacing the shut off valve and installing a frost free fixture. The space where the current shut off valve was located in the basement was tight and he had to work through a small hall in the dry wall to get to it. I was amazed he was able to do that without ruining the drywall and making a larger hole. My plumber was George A. He was prompt, courteous, professional and skillful. I will definitely request him for the next plumbing job we might need. Will also recommend this company!” Ellen

“ I called about my clogged toilet, This thing had been slow and getting worse. I had a tech from another company come out about it a few years ago and they did not consider it to be bad- but we regularly had issues. Now it was badly clogged. It was easy to make an appointment with Cardinal and I like that they give a 2 hour window (not 4) plus call when they are en route. The tech was friendly (Daniel) and gave me his analysis of the techniques that might be needed to clear my clogged toilet. The first thing he tried was successful and the toilet has never worked better. You know how you break a sweat when the dirty water starts to rise - no more! They did a great job.” Bruce
