  Challenge: This crawl space could be described as “high and dry”... but the dirt floor and lack of insulation on the exterior walls made the home’s floor cold during the winter months. 

  Solution: We completely sealed the crawl space from the outside environment, and added spray foam insulation. Spray foam offers a  high R-value, sealing air leaks and also serving as a moisture barrier.

  A Challenging Multi-Level Dirt Crawl Space, Oxford County

  Before

  After

  Problem: This multi-level dirt floor crawl space was a challenge successfully met by our crew! The open vents were resulting in cold floors during the winter. In the summer the crawl space was damp and musty; the foul odour affected the entire home.

  Solution:  We sealed off the open vents and installed a CleanSpace liner vapour barrier system; which totally encapsulates the crawl space. Our crew also applied moisture-resistant spray foam insulation to help make the home more energy efficient.

  Sealing Crawl Space Vents, Southwestern ON

  Before

  After

  Problem:  Open crawl space vents allow for the outside air to easily enter a crawl space. Fluctuations in weather combined with the naturally damp and humid environment in a crawl space means a home is likely to have cold floors, higher humidity and a damp, musty smell.

  Open crawl space vents are also an invitation to pests to live under your home!

  Solution: We replaced all the open vents and installed airtight vent covers. Although the covers are only part of creating a healthy and dry crawl space environment – it’s an important step!

  Fix for a Wet Crawl Space in Southwold, ON

  Before

  After

  Problem:  This wet crawl space was causing problems for these homeowners in southwestern Ontario. The humid and moist environment caused their traditional fiberglass insulation to fall and become ineffective. Their entire home smelled musty as the odours from the crawl space affected their entire home.

  Solution: We sealed off the outside environment which was causing the humid crawl space environment, encapsulating it with our heavy duty CleanSpace® Liner.

  For improved comfort and better energy efficiency, we also used Spray Foam Insulation.

  What a difference!

  Crawl Space Encapsulation London, ON

  Before

  After

  Problem: This dirt floor crawl space is allowing moisture into the home constantly with the earth being exposed. The humidity is high and there are odours in the main level of the home. 

  Solution: By installing an encapsulation system (moisture barrier) we can isolate the home from the earth. We also want to seal off all outside air. This space was also dehumidified to condition the air.
