Colorado Crawl Space Before & After Photos

It was important to these new homeowners to clean up the crawlspace for the benefits of a healthier indoor air quality. We remediated the mold, air sealed the perimeter with closed cell spray foam, & encapsulated the earth and walls - creating storage space & making room in the house for the new addition to the family.  

We removed all the subfloor insulation since it was heavily rodent infested. We Closed Cell Spray Foamed the perimeter rim assembly & encapsualted the floor & walls to create a mini basement. Now it's nice and clean!

The subfloor fiberglass batt insulation in this crawlsapce was acting like a sponge - absorbing moisture from the exposed ground - resulting in microbial growth, falling black visqueen, and the insulation itself falling. We removed the black visqueen barrier and insulation, insulated the perimeter exterior walls with 2" foamboard, closed cell spray foamed the perimeter rim assembly, and sealed up the crawlspace with the cleanspace Encapsulation System. Now the subfloor is exposed for plumbing and electrical maintenance and the crawlspace is warmer. We've removed the moisture and source of the indoor allergens that the homeowners were concerned about. 

This crawlspace had exposed earth and gravel. We installed our drainage matting over the floor and our cleanspace liner over the drainage matting and the foundation walls to seal out groundwater seepage from the crawlspace. We have also created a clean dry environment and plenty of storage space.

This homeowner's primary concern was mitigating the Radon. When other Radon contractors refused to get the job done due to height constrictions - we stepped up to plate. We had to get creative in removing obstacles & hazards - We removed the ducting in our way, remediated the mold & rodent infestation, laid down the liner across the floor & walls, and attached the liner to the foundation walls using closed cell spray foam in the inaccessible areas, ran the necessary perforated & PVC pipes and appropriately sized fans to mitigate the Radon to less than 1 pci/L (less than 4 pci/L is acceptable). This family has the piece of mind they deserve!
