Insulation for Crawl Spaces

Crawl spaces that aren’t properly insulated are prone to water damage from moisture that comes from the ground under your house. This can cause inconvenient (and potentially costly) problems.

If your crawl space is ventilated, it can be hard to keep warm in the winter, and during the summer, it can be difficult to dehumidify, which can result in higher levels of moisture. The professionals at American Insulation can insulate the subfloor and between the floor joists. For unventilated crawl spaces, sealing between the house and crawl space isn’t as important, so in our opinion, it’s best to insulate the walls.

Installing crawl space insulation can help:

  • Reduce your utility bills and maximize the energy efficiency of your home
  • Make your home a more comfortable space
  • Improve the efficiency of your air conditioner and furnace
  • Contribute to a healthier environment
