Reliable Crawl Space Moisture Control in The Greater Hampton Roads Region

Our Team of Experts Offers Moisture Control Solutions For Your Crawl Space.

Stop Moisture Issues Before They Start

Although there are only three primary sources of moisture in a crawl space (humidity, damp ground, flooding/groundwater), they can cause significant issues for homeowners.

In fact, two of the most common results of untreated crawl space moisture are mold growth and foundation damage. Over time, these can result in significant damage to your property or even health issues for those who are exposed to large quantities of mold.

We strategically eliminate any presence of unwanted moisture so that complications don’t arise in the future. With over 250 years of experience between our 35 team members, we’re able to repair any moisture-related damage to your crawl space and ensure that crawl space moisture issues become a thing of the past.

Controlling Crawl Space Moisture

In order to properly regulate crawl space moisture, you’ll need to eliminate the source. Otherwise, you run the risk of experiencing structural damage to your home, which can lead to costly repairs. So, it’s important to seek professional help as soon as possible if you notice water/moisture in your crawl space.

The primary sources of moisture include flooding/groundwater, damp ground, and humidity, and they all need to be accounted for in order to properly treat and protect your crawl space.

The good news is that once your crawl space is properly treated for water and moisture, you won’t have to deal with these problems again in the future.


The source that will need the most immediate attention is flooding, as the moisture of your crawl space can’t be controlled while there is water present in the area. In fact, flooded crawl spaces that are already properly sealed will prevent any water from leaking out.

Our drainage systems, including French drains and sump pumps, are specifically designed to remove large quantities of water so that your crawl space’s moisture can be effectively regulated. If you’ve experienced crawl space flooding, you’ll need to remove the water before these systems can be installed.

Damp Ground

Damp ground can release vapor into the air of the crawl space, which will result in a wet environment over time. After a long enough period, wood may begin to rot even without the presence of standing water.

Since you won’t be able to remove moisture from the soil surrounding your home, encapsulations and vapor barriers will be the most effective method. These will allow you to fully seal the area so that moisture doesn’t affect your crawl space.


As humidity rises, it can contribute to the presence of moisture in your crawlspace. This factor can also seem difficult to accommodate, but it’s easily managed by installing a dehumidifier that will allow you to properly regulate your crawlspace’s condition.

These solutions combined will allow you to have full control over the level of moisture in your crawlspace, allowing you to prevent damage from occurring to your home.

Methods For Controlling Crawl Space Moisture

The condition of your crawl space will dictate what type of treatment it needs in order to get the environment back to normal. Over the years, we’ve optimized our methods for controlling crawl space moisture and broken them down into four categories.

No matter your issue, one (or more) of the following treatment options will be appropriate for your situation.

French Drains/Sump Pumps

With the installation of French drains and sump pumps, you’ll be able to automatically regulate the level of water in your crawl space. As water enters the area, French drains and sump pumps will work on their own to drain any excess fluid and prevent flooding.

Since water won’t be able to accumulate in your crawl space, you’ll greatly reduce the chances of any damage to your foundation occurring. They’re also essential for prepping your crawl space for further treatment options.

Vapor Barriers

When damp ground is openly exposed for an extended period of time, the vapors it produces can lead to a handful of negative consequences. Polyethylene sheeting is used to cover and seal problem areas in order to prevent the accumulation of moisture.

Our vapor barrier options range from 6-millimeter to 20-millimeter polyethylene sheeting. We recommend thicker options for maximum efficiency. However, our thinner options are still suitable options for basic treatment.

Regardless of the chosen thickness, 100% ground coverage and proper sealing are implemented to eliminate the vapors that damp ground gives off.


Without a dehumidifier, you run the risk of outside humidity causing moisture to accumulate within your crawl space. Installing one will help ensure that the air is as dry as possible.

It’s important to note that a dehumidifier will only function optimally if the crawl space is cleaned, cleared of any obstacles, and properly sealed. Otherwise, you may not be able to completely eliminate all moisture issues with a dehumidifier.

Crawl SpaceEncapsulation

By sealing your crawl space, you’ll be able to have full control of the moisture in the environment. A dehumidifier is a necessary treatment along with this process in order to maintain a consistent level of conditions throughout the year.

If there is any flooding in your crawl space, it will need to be completely drained before encapsulation can occur.
