What's Really Happening Under Your Home
Your crawl space problems stem from the “stack effect.” Warm air naturally rises from your crawl space into your living areas, carrying moisture, mold spores, and contaminants directly to your family. Without proper sealing, your crawl space becomes a breeding ground for health hazards.

Why Encapsulation Isn’t Optional
Hidden threats are real threats.
Clogged gutters, poor grading, flowerbeds planted too close, or even a broken water line, it doesn’t take much for moisture to slip into that overlooked layer beneath your floors. From there, it feeds mold, invites pests, and raises humidity throughout your home, even when you don’t see it.
Damp air doesn’t stay in the crawl space.
Once moisture seeps in, it spreads, not just along the walls or floor, but into the structure above. You may notice more humidity in your living space, musty smells that won’t go away, or difficulty keeping temperatures consistent from room to room.
Your crawl space affects the air your family breathes.
A wet, unsealed crawl space can become a source of odors, allergens, and airborne contaminants. Even if you never enter that space, its condition still impacts your comfort, your air quality, and the health of your home overall.

Common Causes of Crawl Space Problems
Crawl space issues, like flooding and moisture buildup, can arise from both natural factors and human-made conditions. Whether water seeps in from above or below, here are some of the top reasons your crawl space may be experiencing trouble:
Poor Landscape Grading
If your yard isn’t graded correctly, rainwater can pool in areas where it shouldn’t, often leading straight to your crawl space.Gutter and Downspout Issues
Improperly installed gutters or downspouts can cause water to collect near your home’s foundation, allowing it to seep into the crawl space.Nearby Flower Beds
Frequent watering of flower beds placed too close to your home can add extra water pressure on the foundation, potentially leading to crawl space moisture.Broken Water Lines
A damaged water line can leak and allow water to infiltrate the crawl space if it’s close to your home.Excessive Groundwater
High levels of groundwater in the soil can affect the health of your crawl space, causing moisture buildup and potential flooding.
Each of these factors can lead to costly crawl space problems, making prevention and regular maintenance essential.

Benefits of Crawl Space Encapsulation
Improved Air Quality
Encapsulation significantly reduces humidity and improves air quality by preventing moisture from entering your home. Removing moisture greatly reduces the chance of mold growth.Energy Efficiency
Because damp air is more difficult to heat or cool, you can save on heating and cooling bills by sealing your crawl space.Protection Against Flooding
If your crawl space is prone to flooding, a water drainage system can be added beneath the vapor barrier to direct water away from your foundation.Extended Structural Life
Moisture can weaken your foundation over time. Our encapsulation helps to prevent damage and preserve your home’s structural integrity.

Frequently Asked Questions:
Birmingham Crawl Space Repair
Crawl space encapsulation describes the sealing of your crawl space and protecting it against the outside environment. The goal is to prevent outside moisture from flowing into the crawl space and causing moisture-related problems.
It is important to get your crawl space encapsulated because not only does it protect your crawl space from outside moisture, but it can also help keep pests out and even provides a passive defense against radon gas.
While the total cost will depend on the size of your crawl space and the extent of any damage caused by moisture-related problems, crawl space encapsulation costs usually range from $1,500 to $15,000. Southern Dry offers both a free inspection and a detailed cost estimate.
Yes! An encapsulated crawl space provides more than just protection for your home against invasive moisture—it turns your crawl space into a usable space! Whether you want to use it for storage, a cellar, or even an indoor garden space, the ability to use the crawl space safely for these purposes will add value to your home.
Breathe easier with a healthier home. The air in your crawl space inevitably flows up into your living space. But with crawl space encapsulation, the air in your crawl space will be kept cleaner and healthier without all that outside air, moisture, and allergens.
Between having a healthy, safe, and usable crawl space or having a dirty, damp, and musty crawl space, it’s easy to see that crawl space encapsulation will only improve your quality of life in your home.
If your crawl space has a musty odor, you may have a moisture problem in your crawl space and mold has started growing in there. Crawl space encapsulation can keep your crawl space safe and dry, which prevents mold growth since mold requires a certain level of moisture to live.
Termites need a certain level of humidity to survive. With crawl space encapsulation, your crawl space and any wooden support structures within will be kept dry, closing the door on any termites looking for a new home.
Rodent pests love looking for dark, damp, and messy places to build their nests and raise their young. That would make a damp and musty dirt crawl space perfect for them. But with crawl space encapsulation, your crawl space can be made clean and dry. This not only deprives potential rodent pests of the moisture they want, but it also can help discourage rodents by depriving them of nesting materials that a dirt crawl space may offer.
