Healthy Waterproofing

You know that smell you associate with old basements? That’s likely mold or mildew caused by seeping water or excess humidity. While it’s typically considered a mere inconvenience, water seepage can not only cause damage to your home, it can impact your family’s health. That’s why basement waterproofing is among the most important, yet one of the most overlooked procedures for many homeowners, which extends to crawl spaces as well. Healthy Air starts beneath your home.

Basement Waterproofing

No matter what material your foundation is built from—bricks, concrete, stone, etc.—seeping water remains a risk as the ground puts pressure on the walls, forcing moisture inside. For homes with basements, a tried and true basement waterproofing process starts with locating the source of any water damage and using a combination of methods to prevent further damage. Each case is different, but an experienced waterproofing specialist can help you decide on the best path for addressing the issues that are specific to your home.

Crawl Space Encapsulation

Just like basements, crawl spaces are susceptible to water damage because they’re the lowest point in your home. To encapsulate your crawl space, the process includes sealing off the walls and/or floors to prevent water seepage from outside and to remove the risk of stale, humid air circulating throughout your home. This sealing process essentially creates a water-tight seal in your crawl space, removing the chance for moisture to enter and cause issues.


Along with waterproofing and encapsulation, you can take steps to remove excess moisture by using an AprilAire dehumidifier. These units are made specifically for basements and crawl spaces.

Dos & Don'ts


contact a professional if you locate or suspect water damage

Standing water, leaks, or puddles in your basement or crawl space could indicate a potential problem. Seek professional assistance to mitigate the issue before it becomes a bigger problem.


neglect mold or mildew smells

Musty smells are indicative of mold or mildew, which spread via spores that can lead to allergic reactions and respiratory issues. If you suspect mold, call a professional


attempt to maintain indoor humidity levels

High levels of humidity can be breeding grounds for mold, mildew, and rot, which can quickly spread through your home. Alternatively, studies have shown viruses thrive in dry air, so finding balance is key to a healthy basement. Try to keep your indoor humidity between 40% and 60%.


forget to divert rainwater

A simple solution to prevent water seepage is to divert rainwater from your downspouts further away from your home. This prevents water from pooling near your foundation where it can cause damage.


consider crawl space encapsulation

It’s easy to put off crawl space encapsulation because you and your family hardly ever retreat beneath your homes. However, that doesn’t make it any less important as Healthy Air begins beneath your home.


assume waterproofing is a set and forget solution

While waterproofing can be extremely reliable, water has a tricky way of finding new cracks and crevices to seep through. Always be mindful of new possible sources of water damage so you can resolve the issue before it’s too late.

Because damp basements promote biological growth, including molds...any moisture problems should be corrected before you proceed.

Not only does waterproofing protect your home and your health. It can also help manage pests and bugs that thrive in moist conditions and help you save money. Remember, a long-term investment that proactively protects your home may be far less than a short-term blow to your budget to suddenly make repairs. Protect your home. Protect your family. Breathe Healthy Air.
