Bathroom sink hot water pipe common problem

After 13 years of using the bathroom sink hot water pipe for hot water it will leak out drops of water for a year until it create water damage molds. You would have to spray Lysol air spray on it and then clean off the mold with bleach water,sponge, face mask,and eye goggles. Next is to call a plumber to replace the sink hot pipe. You can call a church member plumber for help for you to save money or call a local plumber. My church member plumber only charge my mom $300 for any plumbing repair work in her house.
