Crawl Space Ventilation: Guidelines on How to Handle Moisture


A basement crawlspace may be one of the areas of the home that is easiest to overlook. It generally is located out of the way of most of your daily activities, and you may seldom see it. Because of its location below ground level, it may be susceptible to high levels of moisture and humidity. This can result in mold growth and water-related property damage, so it is in your best interest find an effective way to remove the moisture and humidity from your crawlspace. While this sounds like a major task to get started working on, you can easily follow a few tips to get the results you desire.

Identify and Repair the Source of the Moisture
As a first step, take time to explore the crawlspace and to determine where the moisture is coming from. In some cases, homeowners will discover that there is a slow leak in a pipe, and this type of issue should be repaired before the area is dried out. If you cannot access the crawlspace, consider contacting a professional to assist with a visual inspection of the area and to schedule repair services as needed.

Waterproof the Area
Just as you would waterproof a basement, you also should waterproof your crawlspace. The crawlspace may have wooden support beams and other critical features that are important to the structural integrity of the home. When they are wet, they may be more likely to rot or to develop mold growth, and both of these issues can be detrimental to the structural integrity of the home. More than that, mold growth can spread throughout the home. You can work with a contractor to determine the best waterproofing solution for your home.

Invest in a Dehumidifier
A final step to take is to invest in a dehumidifier. These are designed to remove the moisture from the air. Even when the basement is waterproof, it may still have a high level of humidity. A dehumidifier is an effective way to keep this space drier. There are several types of dehumidifiers available for you to use in a crawlspace or a basement, and an HVAC contractor can provide you with assistance with the selection and installation of the dehumidifier that is best for you.

If you are concerned about the potential for mold growth or water damage in your home due to moisture in your crawlspace, now is the time to take action. The longer your crawlspace remains moist or wet, it will be increasingly likely for property damage and other issues to develop. You can follow these steps and can seek professional assistance from contractors as needed to improve the condition of your crawlspace and to protect your home.
