Ideal Crawl Space Humidity As Warmer Weather Approaches Richmond

Spring is right around the corner, but the weather is already beginning to heat up in Richmond and surrounding areas. Is your home as excited as you are? That’s highly doubtful, specifically for homeowners with a crawl space. Your ideal crawl space humidity levels will be tested as the warmer weather approaches, making it important to prepare ahead of time.

Most Richmond natives will tell you the city can become very humid in the Spring and Summer months. The sun may be shining on a beautiful day, but your home’s crawl space is heating up in the process.

Ideal Crawl Space Humidity

Ideal Crawl Space Humidity: What is Relative Humidity?

Controlling moisture accumulation is the key to deterring rot, mold growth and pest infestation. This can be done by maintaining a safe relative humidity in your crawl space. To clarify, relative humidity is how full of water the air is relative to the maximum amount of water it can hold at a given temperature.Ideal Crawl Space Humidity - Moisture Damage

When warm air enters your crawl space, it’s cooled, which raises the relative humidity. As a result, a high relative humidity can cause rot, mold, energy loss and attract pests.

Mold needs at least 70% relative humidity to grow. However, this is considered a loose number. Some molds can grow at a lower relative humidity based on two factors: the relative humidity of the surrounding air in your crawl space to the relative humidity of the surface. These temperature differences can cause mold to grow at lower than 70%.

As you can see, it’s important to monitor your crawl space to prevent costly structural damage. Your ideal relative humidity is 55%, and this should be maintained throughout the year.

Ideal Crawl Space Humidity: Encapsulation

Ideal Crawl Space Humidity - Vapor BarrierThe best way to control humidity is through crawl space encapsulation. Properly sealing your crawl space will prevent water vapors from entering your crawl space, creating a moisture-free and pest-free environment.

Encapsulation involves installing a 20 mil vapor barrier system, sealing crawl space vents and doors, installing a sump pump, and bringing in a dehumidifier. Crawl space encapsulation will quickly reduce humidity and moisture problems by preventing water from entering your crawl space.

Maintaining the ideal relative humidity in your crawl space will deter mold and mildew, which affects the structural integrity and stability of your home.
