Vented Crawl Space Winter Woes

This homeowner tried to make his home more comfortable by applying fiberglass insulation between the floor joists, in his vented crawl space
What Happens To A Vented Crawl Space In The Winter?
Crawl space vents are designed to pull outside air into your home, creating a continuous supply of outside air that moves through the crawl space at all times.
While many would debate the usefulness of ventilating a crawl space at any time of the year, contractors can certainly agree that during cold weather, these vents should be firmly closed. However, the truth of the matter is that few homeowners actually perform this yearly task.
How A Vented Crawl Space Affects Your Home’s Energy Efficiency
The purpose of your crawl space is to house the utilities in your home, including utilities that use energy to create heat, such as your home’s furnace and air duct system, as well as your hot water heater and pipes.
Housing these utilities in the crawl space during the cold winter season means that they will have to continually work harder and use more energy to do their daily task. This has a major impact on your home’s utility bills!

You can see the crawl space list in it’s entirety at the Southface Web site, but as it deals with new construction, I have truncated it here to reflect sealing a crawl space in an existing home.
Here’s the list:
- Moisture can enter the crawlspace when the home is being constructed, creating mold even before the home is completed. Proper drainage, sealing and insulating are important early in construction—before the floor joists are installed.
Rats in the Crawl Space in Hamilton, Ontario
Rats love to live – and die – in damp crawl spaces.
A damp, musty, smelly crawl space is not the best place for a human to live, but mold, mildew, bugs and various other critters love these environments. To eliminate these unwelcome guests, a home owner needs to change the environment.
Omni Basement Systems the basement and crawl space contractor in Hamilton, Ontario who photographed the dead rat, installs the CleanSpace Crawl Space Encapsulation System to help remedy damp crawl spaces. This is a crawl space vapor barrier system that takes into account the crawl space vents and ventilation, the door or hatch, air leaks, conditioning, and more.
