Crawl Space Moisture Solutions

Dry the space beneath you. Protect everything above.

Your crawl space is a key part of your home’s foundation, but it’s also highly susceptible to water damage. Even if you don’t see standing water, high humidity from a dirt floor or open vents can lead to serious problems like mold growth, wood rot, and sagging floors. This excess moisture can also cause unpleasant odors and harmful mold spores to travel from your crawl space up into your living areas.

At SouthernDry, we provide professional crawl space waterproofing services that solve current moisture problems and help prevent future ones. Our custom-designed systems ensure your crawl space stays dry and healthy, protecting your home’s structure and improving your family’s air quality.

Dangers

Why Crawl Space Moisture Is So Dangerous

The problem isn’t just leaks, it’s humidity.

Dirt floors, open vents, and gaps around pipes allow humid air to rush into your crawl space. Once inside, it settles into the wood framing, fueling mold growth and wood rot. You might never step into the space below your floors, but moisture already has.

That air rises, carrying mold spores and musty odors with it.

As warm air moves upward (known as the stack effect), it pulls contaminated crawl space air into your home through cracks, ducts, and framing gaps. The result? Allergy flare-ups, unpleasant smells, and a constant, subtle threat to your indoor air quality.

Wet crawl spaces damage more than just comfort.

High humidity breaks down wooden joists, subfloors, and sill plates, weakening the very foundation of your home. You may notice soft spots, warped flooring, or sagging near walls. Left unchecked, this damage threatens your home’s structure and resale value.

Importance of Waterproofing

Why Waterproofing Your Crawl Space is Critical

Ignoring moisture in your crawl space can lead to a host of problems that affect your entire home.

  • Protects Your Foundation: Excess moisture and humidity can weaken your wooden floor joists and support beams, leading to costly structural damage and sagging floors.
  • Prevents Mold Growth: A damp, humid environment is a perfect breeding ground for mold and mildew, which can trigger allergies and other respiratory issues.
  • Improves Air Quality: A wet crawl space contributes to poor indoor air quality throughout your home. A sealed and dry crawl space helps ensure the air you breathe is clean and healthy.
  • Discourages Pests: Pests like termites, roaches, and rodents are attracted to damp, dark spaces. Waterproofing your crawl space makes it less hospitable for unwanted guests.
  • Increases Home Value: A dry, protected crawl space is a major selling point and signals that your home has been well-maintained.

Our Waterproofing System

Our Crawl Space Waterproofing System

Every crawl space is different. That’s why your Certified Foundation Specialist will design a system tailored to your home’s conditions. We may recommend one or more of the following components:

  • Certified Foundation Specialist installing a channel in crawl space

    Perimeter drainage channel

    Installed at the base of the crawl space walls, this channel captures both floor and wall seepage. Unlike filtered pipes that clog and fail, our self-cleaning, filterless channel is engineered to work long-term, right where the water is.

  • Crawl space encapsulation and lighting

    Waterproof wall membrane

    A flexible liner is fastened to the crawl space walls to direct water down into the drainage channel. This durable material is the same we use for full encapsulations, built to handle long-term exposure and keep seepage off your foundation walls.

  • Sump pump and channel installed in a crawl space

    Sump pump system

    At the heart of your system is a high-performance sump pump. Our setups include primary and backup models, including battery-powered options for power outages or extreme storms. If water finds its way in, it won’t stay.

  • A dehumidifier hung in a crawl space

    Crawl space dehumidifier

    A commercial-grade dehumidifier maintains consistent moisture control, working automatically to prevent mold, mildew, and pest-friendly conditions. It dries the air, stabilizes the structure, and makes sure your crawl space stays forgotten, in the best way.

Southern Dry was not the cheapest but no where near the most expensive.

My crawlspace was wet, moldy, and just nasty. The insulation was soaking wet and it smelled awful. I called five different companies to come out and give me quotes on what they thought needed to be done. I had quotes all over the board ranging from $7,000 all the way up to $48,000. Southern dry…
