Damp Crawl Spaces: Why It’s a Problem & What to Do About It

Many factors, including seasonal changes and leaks, can lead to crawl space moisture and damaging side effects, such as musty odors, strain on HVAC systems, and reduced energy efficiency. Crawl space vapor barrier solutions and other strategies are highly effective for waterproofing a crawl space.

This page explores facts about moisture-related damage and the crawl space repair strategies used to resolve these issues. Let’s get started.

Is a Wet Crawl Space a Cause for Concern?

Yes, crawl space moisture is a concern. Dampness triggers problems, including mold growth, musty smells, pests, and structural damage. These problems worsen over time, becoming costly to address. A detailed inspection is crucial to identify the underlying cause of moisture and determine whether waterproofing a crawl space is necessary.

What Causes Water in a Crawl Space?

If you notice moisture in your crawl space, it’s important to identify the source, which may include:

Burst Pipes: Undetected pipe leaks within the crawl space can increase humidity as the leaking water evaporates.
Water Runoff: Rainwater runoff can infiltrate the crawl space, especially without proper gutters or landscape grading.
Hot, Humid Air: In the Carolinas, the hot summers and humid air may cause condensation in the crawl, increasing moisture levels.
Saturated Soil: Moisture from heavy rains or snowmelt can seep into the foundation soil around your home and evaporate in the crawl space.
Faulty Gutters and Downspouts: Ineffective gutters and downspouts can funnel water toward your home, leading to crawl space dampness.

Crawl Space Waterproofing Solutions

When addressing moisture, one effective approach is to seal off crawl space areas entirely. This strategy prevents moisture infiltration and reduces energy inefficiencies while protecting against mold growth.

Crawl space vapor barriers block moisture seepage from the ground. These robust liners serve as a highly effective crawl space moisture barrier.
Dehumidifiers address external moisture and groundwater issues, preventing mold and rot by reducing humidity to 50% or lower.
Interior drainage systems are essential for removing water by directing it away through a sump pump system to prevent accumulation.

Sump Pumps protect against flooding and water damage by removing water through a pumping system. These pumps are highly effective for waterproofing a crawl space.
Dehumidifiers remove moisture from the air, ensuring a dry crawl space area.
Encapsulation is highly effective for waterproofing a crawl space. This process can seal off crawl space areas to prevent moisture, pests, and air infiltration.

Crawl Space Encapsulation FAQs

What impact does encapsulation have on controlling crawl space humidity?

Encapsulation plays a crucial role in managing crawl space humidity. By integrating waterproofing and dehumidification techniques, encapsulation effectively reduces humidity levels. This process involves sealing off the crawl space from external elements, preventing water and moist air from infiltrating and creating damp conditions. As a result, encapsulation not only lowers humidity levels but also contributes to a drier and healthier under-home environment, safeguarding your property against moisture-related damage. Contact us to learn more.

Should I Use Encapsulation?

Crawl space encapsulation is undoubtedly a wise investment. Wood rot, mold, and humdity are all hazards that encapsulation protects against. It also makes it more difficult for pests to crawl under your house, deterring animals from spreading feces and other foul odors beneath your floors. Not to mention, the clean white design of our encapsulation barrier makes your crawl space appear a lot more welcoming and easier to use for storage! Encapsulation saves you time, effort, and money in the long run.

Can I install a vapor barrier myself?

DIY installations are not recommended due to potential dangers, costs, and temporary fixes. Professional installation ensures proper fitting and sealing of the vapor barrier, and a thorough evaluation of your crawl space for any additional issues.
