Crawl Space Repair Before & After Photos

This homes old 6 mil vapor barrier was ripped and covered in thick layers of mineral deposits. Without realizing how long it had passed since they had last checked their crawl space, they were wanting a long term solution with an encapsulation. For this they called up John's Waterproofing. After learning about the products we use and the fifty years of experience we have, they were ready to get their project rolling!

Customer called due to water getting into crawlspace

When we looked at this crawlspace it was a dirty mess, The dirt floor was damp, electrical wiring was laying on the ground, and the plumbing was sporadic and outdated. Our crew came in and redid the plumbing, lifted up the electrical wires, and encapsulated the crawlspace with TerraBlock, CleanSpace and SprayFoam. 

This homes old vapor barrier had standing water on top of it, which lead to caked on mud. This water moisture had penetrated the old fiberglass insulation, causing it to get heavy with water weight. To solve this water issue, we installed a full crawlspace encapsulation. 

When John's Waterproofing does inspections, one of the first things we take into account is the ensuring all the insulation and vapor barriers are in good condition. In most cases, we find the the fiberglass insulation is falling from the sub-floor and the vapor barriers are crumpled up and exposing the dirt beneath. When we do a full encapsulation the first thing we do is remove those exact things. But, for many homeowners, they don't understand why we have to completely remove them. Fiberglass insulation is the foam material that typically is attached to the sub-floor and around HVAC systems to offer insulation. It is one of the oldest methods of insulation and has been proven not to last when exposed to any outdoor elements. Over time, as moisture seeps into the crawl space, that fiberglass insulation absorbs the moisture in the air causing it to deteriorate. In extreme cases, this is also the root to many mold and mildew problems. By removing all the fiberglass that is sagging and no longer serving its purpose to properly insulate, then we can replace it with our TerraBlock insulation foam that is designed to completely keep water and moisture out. It also improves the homes energy efficiency because TerraBlock is installed along the base of the crawl space versus the sub-floor. This means it can control the environment, regulating temperatures in the crawl space, so that your home doesn't have to exhaust its heating and cooling to keep up with outside temperature changes. Adding to that, it's the same reason we take out a damaged vapor barrier that exposes the earth beneath the home. This is because it offers no protection against the changing environments outside and homeowners end up spending more money on energy costs. Plus, it helps make the crawl space a clean and fresh environment before we start installing our full encapsulation to protect against water damage.
