Steps To Repair A Wet Crawlspace

When you encounter a wet crawlspace in your home, it can cause moisture and mold damage to your home's interior and attract unwanted pests. Preventing your crawlspace from becoming wet is a process that should be taken seriously. Here are some tips to help you remedy the situation to dry out your crawlspace and make the area usable:

Divert Exterior Moisture

One of the first steps you should take with keeping moisture out of your crawlspace is to prevent it from entering the space in the first place. Moisture usually seeps into an interior area of your home through outside groundwater saturation, which can come from high water tables, nearby bodies of water, and excessive precipitation saturating the soil. You can install an exterior drainage system around your home's foundation to capture and divert excess groundwater away from your crawlspace.

You can also build up the soil around your home's exterior to create a slope of the soil away from your home. Then, if excessive precipitation causes the soil to become saturated around your home, the moisture will be prompted to flow down the soil's slope and away from your home. Check your home's exterior gutters and drainage system to make sure any roof runoff is not saturating the soil around your home foundation.

Encapsulate Your Crawlspace

Another method to prevent your crawlspace from becoming moisture-soaked is to seal off your basement crawlspace with the use of a waterproof vapor barrier. This barrier seals in your crawlspace to exterior moisture and keeps the space ventilated with air from your home's ventilation system. This provides your crawlspace with air of a humidity level less than the outside air.

During the encapsulation of your crawlspace, the floor and walls are covered in a durable plastic vapor barrier, and all the seams are sealed to prevent leaks. Any crawlspace ventilation ducts are sealed off to prevent outside air from seeping into the crawlspace. Then, any ventilation ducts and structural pillars are also covered to finish the encapsulation.

Maintain the Crawlspace

It is a good idea to install a hygrometer in your crawlspace so you can monitor the humidity levels in the space. Watching the humidity levels will alert you to any possible breaches in your vapor barrier and their seams, as the humidity levels will rise when this occurs.

It is also a good idea to have your encapsulation inspected by an HVAC technician when your HVAC system is inspected. This will help you maintain the waterproof area, prevent inadequate ventilation to the rest of your home's air, and to repair any damage that may occur.
