I need help here ! I bought a brand new home last year with a cold storage room in the basement. The builder left all kinds of wood in there when they poured the concrete. I noticed upon moving in and long after that the mustiness in that room was unbelievable. I had the builder rip out all the wood and install 2 new vents that were stuck open instead of the flap vents he installed which allowed NO circulation of air. When they ripped out of the wood the guy told me that that wood was basically dripping wet it was so humid. Well 1 month after new vents and ripping out all the wood, I bought a thermometer that can read humidity and as soon as I installed it, it went right up to 100% humidity !!! The mustiness smell is still there for sure and my wife thinks is sickening and disgusting. So here are my questions.
1-Why is the humidity levels so high in that room so high to begin with? 2-How can I ventilate better ? 3-How do I get the smell out of there? 4-Is there a health risk ?Any other help would be greatly appreciated. Ottawa, Canada.
