Mold Awareness Month Tip: When you see signs of moisture damage either on the exterior or interior you can’t just address this at the surface. You have to keep digging until you get to dry materials. If that means tearing out the drywall and the insulation until you get to something dry, so be it. You can’t just fix the surface because it was wet. If you have to replace materials following moisture damage consider using a mold and moisture resistant drywall and a smart vapor retarder with your insulation to add protection to your wall assembly. You will be building in more robustness to an area of your home that is apparently susceptible to moisture intrusion.
That’s from the outside too. If you find some water damage around your window and you tear it out you can’t stop there. Take your screwdriver or awl and probe the wood behind it to find out how far the damage goes. If you don’t correct the problem at the source and replace all the damaged materials, the chances of mold occurring in this area are very good..
So, don’t stop at the surface or just treat the symptoms. You have to exhaust the symptoms and get to the source.
Remember, if you see moisture damage whether inside or outside the building don’t stop digging and probing until you get to dry.
