Unsealed crawl space vents
An undeniable sign of a problem crawl space is open or unsealed vents. Outside air is affecting the environment inside the crawl space in an unhealthy manner.
The fibreglass insulation was absorbing the excessive humidity in the space, and in places had even fallen to the ground. Whether wet or fallen: the insulation isn't doing any good!
Insufficient supports and mould growth
Our inspector noted the growth of mould and mildew - again due to the unhealthy humid environment. The musty, damp smells in the home are caused by mould and mildew, as the spores make their way up and into the home above.
"Laying down plastic doesn't work!"
The homeowners installed plastic on the ground as a way to keep the humidity down, but it was flimsy and not properly sealed to the spray foam insulation.
Keeping the outside air where it belongs... outside!
Encapsulating the space
This heavy duty liner we installed, along with the improved drainage in the space, will keep the unhealthy, humid environment from affecting the space.
Sealing the liner
We sealed the liner together, at the base of the piers and along the existing spray foam insulation - which was in good shape. Now the space is clean, dry and healthy!
