Expert Plumbing and HVAC Service Across Sterling, VA

Sam R and Anthony P from Cardinal Plumbing were great - knowledgeable, courteous, and professional. They even caught a detail the county inspectors had missed (by adding a strap around the blue expansion tank in the upper right of the photo). Thanks for great service!

Sam did a great job. Super friendly and helpful.

Had a major water leak at our irrigation main control area. I called several other emergency plumbers, and Cardinal gave me the quickest response time of 30 minutes. Other companies quoted me 3-8 hour response times, which wouldn’t cut it with the amount of water that was gushing out of the pipe....

Other companies quoted me 3-8 hour response times, which wouldn’t cut it with the amount of water that was gushing out of the pipe. Cardinal advised that their tech Sam R. would be there in 30 minutes. Sam called me right afterwards, and told me he was en route. He arrived in less than 30 minutes, figured out how to shut off the water to our irrigation system from the control inlet, diagnosed the issue (PVC pipe sheared at the threads), and performed an emergency temporary repair. The folks who answered the phone at Cardinal were terrific, professional and very accommodating. Sam R. was super fast in his response, profess Close

Sam was extremely professional and took care of our problem with our kitchen faucet. I highly recommend this company!

During a final walk-through for my buyer, I found a very large puddle in the basement and evidence of something leaking. I called Cardinal, and they sent out Yaya, one of their technicians, very quickly To help us diagnose the issue and get a quote before my clients took ownership of the new home....

We were able to work through a Solution that everyone was happy with. I’m so grateful for the fast response and expertise from Cardinal and from Yaya. This is not the first time they have helped me Take great care of my clients and make sure that they have the information that they need while under a deadline. Highly recommend! Close

Sam was AWESOME! I was able to schedule a next day appointment for a water heater issue. Sam was extremely professional, knowledgeable, and efficient. He also identified a few other items for potential replacement but was not pushy about it. I will absolutely use Cardinal Plumbing again in the futur... See more Sam was AWESOME!
