The common signs of poor crawl space insulation can be felt even when you don’t go inside your crawl space. Your crawl space does more than house your Youngstown home’s pipes and ductwork: it can actively change the temperature and air quality in the rest of your house. When the air outside makes it inside your crawl space, it rises into your home, leading your HVAC system to work overtime in order to keep the temperature stable. If your home feels hot during the summer and cold in the winter despite constantly blasting the AC or furnace, then you likely have a crawl space insulation problem. Another way to tell would be with any existing insulation in your crawl space. Crawl spaces are usually insulated with fiberglass, an absorbent material made of fine glass. It takes in the moisture in the air and absorbs it, but if it takes in too much, the weight of the moisture causes the material to sag and break apart. If you go into your crawl space and touch the insulation material and it’s soaked, you’ll know why you’ve been having thermal control problems in your home. Soggy, old insulation material cannot do its job right, so you will have to replace it. If you have an insulation material that isn’t fiberglass, another problem sign would be mold. Other insulation types are made of organic materials, so mold prefers to occupy those kinds of products. The spores from the mold growth in your crawl space make their way into your home because there’s no proper insulation blocking the airways, so the moment you see mold, you need to replace your insulation for the health of your crawl space and those living in your home.
