How to Prevent Mold In a Crawl Space, Step by Step

Check out each of these suggestions in greater detail so you know your property is in great shape from the ground up!

Install a vapor barrier.

A vapor barrier consists of thick plastic sheeting placed over the crawl space ground. This barrier prevents moisture from seeping into the crawl space from the ground. To prevent mold, install a high-quality vapor barrier and ensure it covers the entire floor area, overlapping seams, and the walls.

Invest in full encapsulation.

Crawl space encapsulation seals off and protects the crawl space completely. It involves covering the crawl space floor, walls, and ceiling with a durable, heavy-duty plastic sheet. The goal is to create a sealed and conditioned environment that keeps out moisture.

In some cases, a contractor might install insulation along the walls or floor for additional protection. Crawl space encapsulation is an effective solution for homes located in humid or damp environments, or those experiencing moisture-related problems. This includes high humidity, musty odors, or structural damage caused by excess moisture.

Improve ventilation.

As with any other area of your home, improving crawl space ventilation helps avoid mold growth. However, closing up the crawl space can diminish this ventilation, increasing the risk of mold. In turn, adding ventilation can reduce mold risk.

To improve ventilation in the crawl space, install new vents. These are openings in the foundation walls that allow for improved circulation. Also, homeowners need to make sure the vents are clear of any obstructions and are in good working condition.

Also, in cases where natural ventilation is insufficient, you can use mechanical ventilation systems. This includes fans or dehumidifiers. Fans in the crawl space draw in fresh air from the outside and exhaust stale air. Dehumidifiers remove excess moisture from the air. Both keep the space drier and less prone to mold growth.

Insulate the space.

Proper insulation regulates temperature and reduces condensation in a crawl space. Rigid foam insulation or closed-cell spray foam insulation both protect against moisture. Also, these prevent cold surfaces that increase the risk of condensation. Reducing condensation can mean less risk of mold growth.

Maintain your property’s gutters and downspouts.

Gutters and downspouts direct water off the roof away from the home’s foundation. In turn, it’s vital that you keep them clog-free and maintained properly. This means keeping them clear of debris and without leaks around connectors.

Grade the soil.

Grading refers to angling soil on your property. A proper grade means that the soil runs downhill slightly, away from your home. This downward angle allows moisture in the soil to run toward a street or drain rather than gathering in the crawl space.

A landscaping engineer can tell you if your property’s soil needs better grading. They can test its moisture levels as well. In turn, you can decide if it needs a French drain or other irrigation system. These systems work well to keep moisture away from crawl spaces and avoid mold growth.

Perform inspections regularly.

Mold doesn’t typically grow and spread overnight! In turn, regular inspections can help keep mold growth to a minimum. With this in mind, regularly inspect your crawl space for any signs of moisture, leaks, or mold. Address any issues promptly to prevent further mold growth or water damage.

How Serious Is Mold In a Crawl Space?

Homeowners should take mold in a crawl space very seriously! That mold can spread quickly and risk costly damage and health issues. Consider these in more detail:

  • Mold in a crawl space risks structural damage to your home. Mold feeds on wood, insulation, and drywall, risking decay. In some cases, this can compromise your home’s structural integrity, risking costly repairs and renovations.
  • Home occupants can inhale mold spores, risking respiratory problems, allergies, and other health issues. This can also aggravate asthma symptoms, respiratory infections, allergic reactions, and more health conditions.
  • Mold contributes to higher energy bills in your home! Excessive moisture decreases insulation effectiveness, leading to heat loss in winter and heat gain in summer. In turn, a home’s HVAC system needs to work harder to maintain indoor temperatures, leading to higher utility bills.
  • Mold growth often means unpleasant smells throughout a home. If this results from mold in a crawl space, note that carpet shampooing and other cleaning won’t address those smells. In turn, it’s vital to tackle and prevent mold along your home’s underside.
  • Mold in a crawl space can compromise home values! If an appraiser notices mold during a home inspection, a potential buyer may be reluctant to purchase the property. In turn, its value drops. Addressing mold in the crawl space and ensuring a mold-free environment helps protect your home’s value.
