The crawlspace needs to be insulated properly. So many people believe attaching fiberglass along the underside of your home will keep your home insulated. However, it absorbs moisture, holding it against the homes wooden beams, and allowing mold to fester. This home suffered from this issue, and to address it, the homeowners needed to tackle the mold and what caused the mold so it wouldn't end up coming back. To keep their home healthy, a full encapsulation was installed, properly insulating the home and preventing mold.
This before and after shows that process of applying Spray Foam insulation to the walls of the crawlspace after Cleanspace is installed. Insulation is not needed on the sub-floor because the Spray foam on the walls is working with the cleanspace to encapsulate, waterproof, and insulate. They work better together than apart! Spray Foam is closed-celled so it will not allow water to collect or stick to it.
The before picture shown here is a perfect example of an unhealthy crawl space. The after picture is the same crawl space encapsulated in CleanSpace creating a clean, dry, healthy environment.
When moisture is a constant issue in the crawl space, this can lead to a plethora of issues. For this home it meant that the old fiberglass insulation was water logged and drooping from the HVAC systems. There was also a significant amount of debris that had been caked over the old vapor barrier, and a few wooden posts were damp, but not quite yet irreparable. To get the space healthy we would install a full waterproofing system. We installed a interior perimeter drain system which would collect groundwater and channel it to a newly installed TripleSafe sump pump. From here the water is discharged away from the home. TerraBlock insulation was than laid over the dirt floor and CleanSpace wrapped over it. CleanSpace is a 20 Mil vapor barrier with a woven fiber through it which helps to make it more durable and helps it to protect your home.
This homes crawlspace dirt floor was moist to the touch, and mold spores were creeping up some of the wood. To address the issue we installed a full encapsulation system to keep this space dry and healthy.
