Nelson Mark Plumbing did a very poor job in repairing my damaged pipes in the basement. I was very disappointed with their service and I do not recommend you to do the same. They only seemed to repair the damage when in fact they actually made it worse. After the so call completion of the job, my pipes bursts and the water flooded the basement. With my luck it happened when I was on vacation. The company did not own up to evening providing further assistance in reducing the cost of the damage. That was very shocking. Moreover, their inadequate services were very expensive. They may seem friendly but their unskillfulness is fully shown in their craftsmanship.
