Demarcus was amazing to work with and can be trusted. His prices are reasonable and his work is excellent. Thank you Demarcus for a same day service and fix. My toilet was leaking due to a crack in the porcelain. He made sure it leaked no more by getting me a new toilet. He made sure I understood exactly what he was doing to fix the problem. Thanks again.

I contacted Demarcus with Plumb iQ this morning about issues with two of my toilets, and I couldn’t be more impressed with the service. He was able to come out the same day and quickly take care of both repairs. Demarcus was extremely knowledgeable and took the time to clearly explain what needed to be done and why. It’s not often you find someone who is both efficient and thorough. Highly recommend him if you’re looking for reliable and professional plumbing service!

Highly recommend Mr. Demarcus from Plumb iQ—easily one of the best plumbers in the NOVA area! On his first visit, he explained everything in a way that was super easy to understand and straightforward. Today, he arrived right on time, did a fantastic job, and made sure everything was good to go. Just look at how neat and well-organized the pipes are! Will definitely call him again for any future plumbing needs.

Demarcus did a great job diagnosing a plumbing issue in my basement bathroom, recommending a resolution, ordering and replaced the new toilet quickly. I will work with him for all plumbing needs moving forward.

Today we received impeccable service at an exceptional value by Plumb IQ. Demarcus, who is the owner and operator, responded to our request for an assessment of our leaking shutoff valve assembly. He provided same day service and completed the work promptly and at a fair price. This is our 2nd five star experience with Plumb IQ and will be referring his services to friends and neighbors. Thanks again Demarcus!!
