Transformation of Crawlspace in Portland, OR

This customer found a big mess in their crawlspace with falling insulation, water, rodent infestation and mold. To address the issue we installed a full encapsulation. 

Crawlspace Insulation Made to Last in Portland, OR

Many companies still like to use fiberglass as insulation in a crawlspace, but since it is made to exist within a six sided box, a crawlspaces environment doesn't work for it. The access to moisture and critters causes many issues. It is an inviting bedding material for some animals, and also absorbs moisture, holding it against wooden portions of the foundation, leading to mold and mildew. This homes fiberglass was falling down from moisture and had mold spores. After clearing the crawlspace, we applied mold X and did a full encapsulation to give this home insulation made to last!

This homeowner called us up for a vapor barrier replacement. Their old fiberglass insulation had water vapor getting into it and that would pull the insulation down and cause the homes heating bills to go up.
