Frequently asked questions

What is a crawl space?

A crawl space is an alternative to a traditional basement that creates a barrier between the ground and the floor of a house to protect the latter from rising damp. The space cannot be converted and can be between 20 and 180 cm high.

Why is my crawl space wet?

Soil exposed to the open air creates water vapour that evaporates into the crawl space and eventually into your home. In addition to groundwater seepage, there’s often seepage from the outside. Water can therefore enter under the footing , between the footing and the wall, through cracks in the wall or any other unsealed area. This water evaporates upwards, while increasing the humidity of the crawl space. Take care if your beam, joists or any other part of your structure is made of wood, as contact with water and humidity can affect the integrity of your entire structure.

How do you get rid of moisture and contaminants in a crawl space?

To keep mold from spreading and impacting your health and your home, you need to act quickly to decontaminate the crawl space. Then you must repair, seal and block the infiltration points, install insulation between the house and the ground soil, and ensure sufficient air circulation by installing a high-performance dehumidifier in the crawl space.
