Here, you can see a very spacious crawlspace in Shepherdsville, KY. Unfortunately, this crawlspace has two nasty problems: mold and moisture intrusion. How did this happen? Due to an elevated relative humidity, condensation has created a mold problem. Groundwater intrusion and lack of a vapor barrier have allowed moisture to come in. In this photo, you can see where the mold remeditation team has laid down plastic in order to remediate mold from the wooden subfloor joists. This plastic will be removed and properly disposed of in order to create a clean and healthy crawlspace.
In this photo, you can see the mold remediation has begun. The mold removal team is drawing air out of the crawlspace and filtering it, while scrubbing down the subfloor. The mold spores and fungal debris will fall on this temporary plastic, which will then be removed and disposed of.
In this photo, you can see that the subfloor joists are now free of mold spots and fungal growth. The homeowners were excited that they would not have to smell mildewy, stale air anymore. Why are they smelling mildewy, stale air? It's due to the "Stack Effect", where your home's pressure draws air up from the lowest floor of the house, in this case the crawlspace, and that air disburses through the home, until it flows out from the attic vents.
Here is a before shot of mold and fungal growth along the subfloor joists in the crawlspace. Each joist will be individually scrubbed and washed down with powerful disinfecting agents to kill the existing mold and minimize the risk of mold spores becoming air borne.
Here is the same subfloor joist after it has been scrubbed and treated. The growths are gone and the homeowners were happy to discover that the joists had not become warped or bowed from the constant moisture.
In this picture, you can see that the mold remediation equipment has been removed and the Healthy Spaces crawlspace encapsulation team has begun rolling out the "dimple roll". This product creates a smoother finish under Cleanspace, but it also helps direct ground moisture away from the CleanSpace vapor barrier.
In this photo, you can see that the Healthy Spaces team has begun covering the dimple roll with CleanSpace. This 20 mil thick barrier is guaranteed against rips, tears, and water on top of the liner for 25 years. The Healthy Spaces team has finished testing the sump pump and drainage system, and will now finish encapsulating the crawlspace. The homeowners will have lower relative humidity, higher indoor air quality, and a dry place for extra storage!
Vented dirt crawlspaces are pretty dirty places to work and they can cause indoor air quality problems for your home. In turn, lower indoor air quality can cause increased allergy and asthma symptoms for your family.
