The Roanoke region has already experienced it all in 2025 — temperatures bouncing between warm and cold, days filled with sunshine, and torrential rains that caused flooding. As the weather changes, the needs of your crawl space change, too.
Here are some of the most common challenges to maintaining your crawl space during the spring in Southwest Virginia. They all start with moisture and warm weather.
1. Moisture & Humidity
Roanoke sees an average of 3 inches of rainfall each in April and May, and a few heavy downpours are to be expected.
Note: In Roanoke, you can see if your property is within a flood zone by using the City’s Real Estate GIS or FEMA’s National Flood Hazard Layer.
All this moisture from rain and stormwater runoff can easily seep into your crawl space, especially if it’s not properly sealed. Plus, all this drives up humidity levels as spring warms into summer, and your crawl space may need a dehumidifier.
Persistent dampness can lead to mildew and mold growth, wood rot, and at worst, structural damage over time. A wet crawl space also contributes to poor indoor air quality throughout your home, triggering health concerns ranging from allergies to sinus conditions.
2. Pests and Termites
Pests love to nest in warm, damp crawl spaces. And now, with spring temperatures on the rise, termites and other insects are becoming increasingly active. Termites seek out moist environments and can silently cause major damage to wooden beams and joists. Rodents also look for shelter in the sheltered, darker parts of your home, often entering crawl spaces through small cracks or vents.
3. Ventilation and Odors
Many older homes in Roanoke were built with crawl space vents that open and close, something once thought to control crawl space moisture levels. However, in Southwest Virginia’s climate, these vents actually let in more moisture and humidity, leading to musty odors and mold.
If you’ve noticed a persistent smell in your home that you can’t quite place, you should check your crawl space for moisture issues.
Energy Efficiency and Insulation
Did you know that your home’s energy efficiency relies on a well-insulated crawl space?
While you’re in spring maintenance mode, be sure to inspect your crawl space insulation. If you have cracks in your foundation or missing insulation, that allows humid air to enter in the spring and summer, forcing your heating and air conditioning system to work overtime. Encapsulating the crawl space and installing proper insulation can make your home more comfortable and reduce energy bills.
