Ineffective Sump Pump
Because of the old vapor barrier surrounding the sump pump, it makes it a little hard to see but you can see that it's covering the sump pump, which makes it very difficult to effectively collect water and drain it outside.
Water on Top of Vapor Barrier
When you have water sitting on top of your vapor barrier, it's doing the complete opposite of what a vapor barrier should be doing! A vapor barrier is supposed to stop water vapor from passing through the crawl space ground, up into the crawl space, and eventually making its way throughout your home due to the stack effect. Having water on top of it is allowing all that moisture into your crawl space, which will eventually create mold and cause the insulation to fall down which is what you can see is happening here.

Sagging Wet Crawl Space Insulation
Fiberglass batt insulation used to be installed between joists and vented the crawl space so outside air could circulate beneath the house. This is the worst thing you could do for your crawl space! The cotton-like material absorbs moisture, causing it to become soggy, and it'll lose its R-value. Aside from it creating a soggy mess, the wet material creates conditions that are ideal for mold to grow.
Insulating Rim Joist
Using spray foam to insulate the rim joists in a crawl space, allows the foam to expand, filling every gap or crack along the way. Because it expands to fill gaps and cracks, it's best used to air-seal and insulate the rim joist that extends around the house. This is where most energy-wasting air leakage takes place in a crawl space.
Crawl Space Vapor Barrier
A vapor barrier slows or prevents the evaporation of ground moisture into the crawl space air. Installing CleanSpace 20 mil vapor barrier is a thick plastic liner, similar to a pool liner, that will completely seal off your home from the earth.
CleanSpace Vapor Barrier
CleanSpace is bright white, which dramatically transforms your crawl space from the nasty pit it was to one you wouldn't hesitate to slide around in.
Crawl Space Sump Pump
An important part of a sealed crawl space is having a reliable sump pump system. Our SmartSump crawl space sump pump comes equipped with an alarm and a battery backup sump pump should you choose to add it. It's exactly what you need to ensure a dry crawl space all the time!
Open Crawl Space Vents
With open vents in your crawl space, it's allowing outside air into the crawl space. That outside air is unconditioned (not heated or cooled with air conditioning) and brings in heat in the summer and cold in the winter.
