"I've learned from experience that it's the Harden way or the wrong way. Harden Custom Homes does an amazing job. They waterproof all the areas where running water is located or can touch. They use a fiberglass board that will never mold or mildew if water were to touch it. AND THEN they even paint over that with a waterproofing sealant. Everything Mark Harden does for his homes is really the tried and true best way to do it. He is competitively priced and extremely detail oriented. I couldn't be happier with the quality I have seen in his work. Nothing short of amazing."
