Moisture control is an important factor in protecting your home and health. Uncontrolled moisture can lead to mold growth, rotting wood structures, rusting metal components, and other issues. It can also create a damp environment that can be dangerous for humans and pets. To protect against these problems, it’s important to keep your crawlspace dry.

Why is Moisture Control Important?
No matter how large or small a crawlspace may be, it is imperative to have adequate ventilation, a ground covering, and moisture management systems installed. This is true for both residential and commercial crawlspace.
The presence of an excessive amount of moisture in crawlspaces and basements is the most typical problem encountered by homeowners in Charlotte, NC. Because these components are not given the attention they require on a regular basis, moisture problems frequently grow and cause substantial disruptions to the structural components of the home as well as the overall comfort of the people who live there.
When there is an excessive amount of moisture, the crawlspace becomes an ideal environment for the growth of mold and mildew.
When coupled with the air that will eventually be recirculated to the various portions of the living environment, these microorganisms do not contribute anything beneficial. Instead, they provide a number of health hazards, such as allergic reactions, breathing difficulties, and a variety of other respiratory disorders.
In addition, an excessive amount of moisture can cause damage to the structure of your residential or commercial property as well as the furnishings within it. They bring about the rot that affects the foundation by affecting the wooden components. You may also notice a difference in temperature if the crawl area has an excessively high relative humidity.
Because of this, your heating and cooling system needs to operate at maximum capacity, which will eventually lead your monthly energy bill to shoot through the roof.
Ways to Control Moisture in Crawlspace
Controlling moisture in a crawlspace is essential to prevent mold growth, wood rot, and structural damage. Here are several ways to effectively manage water in a crawlspace:
- Encapsulation: Crawlspace encapsulation involves covering the floor and walls with a moisture barrier, such as a thick plastic or specialized vapor barrier. This barrier helps to seal out moisture from the ground and prevents it from entering the crawlspace. The barrier should be properly installed and sealed to create an airtight seal.
- Proper Ventilation: Ensure the crawlspace has adequate ventilation to promote air circulation and reduce moisture buildup. This can be achieved through vents or mechanical ventilation systems such as fans or dehumidifiers. However, sealing the crawlspace completely may be more effective than relying on ventilation alone in certain climates or situations with high humidity.
- Drainage and Grading: Ensure the ground around the crawlspace slopes away from the foundation. This helps to direct rainwater and surface runoff away from the crawlspace, preventing water accumulation. To divert water from the foundation, install and maintain proper drainage systems, such as gutters, downspouts, and French drains.
- Sump Pump Installation: If water accumulates in the crawlspace, installing a sump pump can be beneficial. A sump pump helps to remove water that collects in a sump pit and pumps it out and away from the crawlspace. It is particularly useful in areas with a high water table or frequent flooding.
- Insulation: Insulating the walls and floors of the crawlspace can help regulate temperature and reduce condensation. Insulation also acts as a barrier against moisture intrusion. Choose insulation materials resistant to moisture and mold growth, such as closed-cell spray foam or rigid foam board insulation.
- Proper maintenance: Regularly inspect the crawlspace for signs of water leaks, condensation, or moisture-related issues. Repair any plumbing leaks, fix damaged or malfunctioning gutters and downspouts, and address any problems promptly to prevent moisture buildup.
- Dehumidification: If the crawlspace continues to have moisture issues, consider using a dehumidifier specifically designed for crawlspaces. These dehumidifiers can operate in low-clearance spaces and help maintain optimal humidity levels by removing excess moisture from the air.
Always remember that the optimal method of moisture control in a crawlspace may change depending on variables, including climate, local building standards, and the crawlspace’s unique qualities. If you need help figuring out how to deal with excess moisture in your crawlspace, call the Freedom Crawlspace Services experts.
Best Moisture Level Range for Crawlspace
The best moisture level range for a crawlspace typically falls between 30% and 60% relative humidity. This range helps prevent mold growth, wood rot, and pest infestations. Here’s a breakdown of the recommended moisture levels for a crawlspace:
- Relative Humidity (RH): Relative humidity refers to the amount of moisture in the air compared to the maximum amount it can hold at a given temperature. For a crawlspace, it is generally recommended to maintain a relative humidity level between 30% and 60%. This range balances preventing excess moisture and avoiding overly dry conditions.
- Moisture Content of Wood: Considering the moisture content of the structural wood components in the crawlspace is important. The optimal moisture content of wood typically ranges from 12% to 20%. This range helps prevent wood decay caused by excessive moisture while avoiding issues related to overly dry conditions, such as wood shrinkage and damage.
However, climate, local building codes, and construction materials can affect crawlspace moisture levels. Instead of Freedom Crawlspace Services, consult contractors, house inspectors, or moisture management specialists for specific crawlspace recommendations. A moisture meter or hygrometer can help you maintain crawlspace humidity.
When to Install a Moisture Barrier
Installing a moisture barrier, also known as crawlspace encapsulation, is typically done during the construction phase of a building or as a retrofit measure to address existing moisture issues. Here are some situations when it is advisable to install a moisture barrier:
- New Construction
- High Moisture Levels
- Mold or Pest Problems
- Insulation Upgrades
It is important to keep in mind that only trained specialists like those found at Freedom Crawlspace Services should install a moisture barrier in your crawlspace. We can evaluate your unique circumstances, suggest the best materials and methods, and supervise the moisture barrier installation to guarantee its optimal performance.
