Colorado Crawl Space Before & After Photos

The homeowners contacted us about an odor emminating from the crawlspace. Upon entering the crawlspace it was clear that the source of the odor was dirty standing water on top of the temporary 6mil liner. With a little investigation work the water source was determined to be a plumbing leak. We bagged and removed the old liner and replaced it with a permanently fastened & Sealed 20 mil, anitmicrobial, cord reinforced CleanSpace liner.

We pulled out years of rodent carcasses, droppings, pine needle bedding, and pine cone food storage from this crawlspace. The earth was lightly regraded for the durable encapsualtion system. We boarded up the holes where rodents had chewed through, added copper wire mesh to and penetrations, and closed cell spray foamed 2" - 3" thick onto the perimeter rim assembly. The walls were already insulated with 2" foamboard, so we sealed the gaps between these as well and tied our floor liner into the 2" foamboard - which doubles as a wall liner to deflect foundation wall moisture down under the liner. 

Rodents had made a pretty comfortable home in this crawlspace. We cleaned up the nests and debris to lay down our dimpled drainage matting and 20 mil thick CleanSpace liner, which we fastened and sealed around the perimeter. Then we reinsulated and sealed up the air gaps around the rim joists & sill plates with closed cell spray foam to help prevent any critters from entering in the future. 

This crawlspace was used for storage of building maintenace items, but was getting lost to the dust and debris. We removed the debris and existing loose layed liner. After installing the CleanSpace Encapsulation System we were able to shut down the dust and create a "Clean Space" to store the salvaged building maintenance items.

This crawlspace needed rodent infested insulation removed & replaced. While we were there we air sealed the perimeter rim assembly to shut down the air & pest infiltration. Copper wire mesh is stuffed into any cracks or crevaces 1/4" or greater before we apply closed cell spray foam 2" to 3" to the whole face of the rim joist,  overlapping the sill plate, & onto the top of the concrete foundation wall. This prevents rodents from chewing through the spray foam. We also bagged and disposed old building materials and clutter. Then we installed an isulation barrier to help keep the air clean and free of fiberglass particles - especially with the wine cellar's air conditioning unit pulling air from the crawlspace. Lastly we HEPA vaccumed the horizonal surfaces creating a clean storage room for the new owners.
