Mold in the crawlspace

A problem with a crawl space, often also means mold and rot.

It is high humidity that is the most likely causes of the unpleasant smell that floats in the air and the rot that invades the wooden joists. It is also the one that slowly but surely attacks the structure of your home and gradually weakens it.

Did you know that mold appears on organic building materials when humidity is high ? In the long term, we can even witness the development of rot.

In the crawl space, the mold development is triggered when 60% humidity is maintained for a prolonged period of time. Water vapour is released from the soil into the air. It then condenses in the crawlspace. The result ? An ideal living environment for the development of mold.

In Quebec, due to changes in seasonal temperatures, mold problems in the crawl space are widespread. That’s why it’s so important to have yours checked.

• Do you see mold in the house, especially on the ground floor or at the bottom of the basement walls ?
• Is there condensation on the pipes inside your home, for example, on the plumbing pipes ?

• When you look at the dirt floor, do you see water, especially after a downpour ?
• Do you see sagging structure of your home ?

If you answered yes to one or more of these questions, you may be right to be concerned. Each of these factors may indicate a problematic crawl space, which poses a considerable risk to the strength and safety of your home. So, don’t delay, look for a solution quickly.

What if I find these signs ?

• Dry the crawl space : In the presence of water in the crawl space, it is imperative to drain the water and dry out the crawlspace. After consulting with an expert in the field, you will determine the best course of action. Sometimes it is necessary to install a French drain and/or a sump pump. These two measures can prevent possible accumulations of water.

• Sealing the crawl space : Depending on the case, it becomes necessary to insulate the crawl space with a vapor barrier. This the only way to completely eliminate the humidity that comes from the ground. Once sealed, the crawl space of your home is protected from the primary source of moisture.

• Dehumidify the crawl space : Finally, it may become important to filter and dehumidify the ambient air to prevent the formation of condensation associated with the variation in seasonal temperatures. To do this, you can choose to have a system of dehumidification and filtration installed. This ensures good air quality in all seasons.
