Hello all, I'm hoping to finish my basement to add an extra room for listening to music. The basement has brick walls. One corner has mold growing on it. When I bought the house I painted three coats of Dry Lock on the bricks walls and the mold is still forming on that corner. I installed a dehumidifier that drains outside. Yes, I jimmy rigged it with a condensation pump drain outside. It didn't help the mold. I spoke to two contractors. The first contractor said I have a hydraulic water problem, basically ground water making the bricks wet. He wants to break the concrete and install a drain pipe on the outside of the house, to drain the water away from the house. The contractor quoted me $10,000 for the drain. The second contractor wants to install an E-Z Breathe system. I think it just brings fresh air into the house from outside. I don't think I like the sound of that. He wants $2400 to install the machine. Am I overthinking this? Is it just a simple minor problem that I can handle myself. I'd rather fix it myself, with friends.
