Crawl spaces are very susceptible to water or structural damage. Over time, this damage can lead to other issues like mold growth, pest infestation, or uneven floors inside your home. Crawl spaces are easy to ignore since they’re not actually inside of your home, but just like any other room of the house, it’s important to check it for any problems that could be health-hazardous to you and your family.

Symptoms to Look Out For

Moldy Crawl Space

Mold inside your crawl space is an issue that will undoubtedly get worse if left untreated. Damp environments are highly susceptible to mold growth, and we have plenty of humidity in Missouri negatively impacting the dampness of your crawl space each and every spring and summer. So, if you notice any mold in your crawl space, it’s a tell-tale sign you likely have a moisture issue as well.

Musty Odors In Home

Similarly, if you notice musty odors inside your home, it is likely a sign of mold or mildew issues in your crawl space. The air circulation in your crawl space acts in a manner that’s called “The Stack Effect”, which means that musty air lingers in your crawl space before exiting up, through the floor joists and then through your home itself. This happens because, as you may have felt, your crawl space is the coldest part of your home. Moist, humid air enters your crawl space in warm months through your vents and foundation walls, festers, and then eventually rises to the warm air above. An unkempt crawl space can thus impact the air quality inside your home, so it’s important to repair any moisture and high humidity in your crawl space because it directly results in the health and safety of your home and family.

Sinking Floors

The floor joists in your crawl space can weaken over time from water damage and moisture or high humidity exposure, causing the floors inside your home to sink or sag. If you notice any seemingly sloped or unlevel floors inside your home, you could have structural issues in your crawl space below.


A humid crawl space is typically a sign that too much moisture is being let into your vents and foundation walls, which are either concrete, stone or brick and therefore porous. As is the case with any crawl space issue, crawl space areas damaged by high humidity can worsen over time. After addressing any water issues and sealing or encapsulating your crawl space, you’ll need a high-performing dehumidification and air filtration system to effectively monitor your foundation’s relative humidity and prevent future moisture build-up problems from occurring.

Bugs in Basement or Crawl Space

Bugs and other pests are unwanted in general, but vented, dirt crawl spaces will unfortunately let pests in from time to time. If you notice an increase in unwanted visitors, it could be a sign of crawl space moisture issues. Bugs love to live in dark, damp places, and thus obviously find musty crawl spaces to be particularly attractive habitats. Like with any ecosystem, little bugs entice bigger bugs, and bigger bugs serve as a tasty meal for rodents, which attract bigger rodents or snakes. This is a huge problem to have underneath your home. Fortunately, we can help make your crawl space clean, dry, and safe. If your crawl space is clean and dry, pests won’t find any reason to live there. And if it’s sealed, they can’t get in.

Crawl Space Flooding

Flooding in your crawl space could be a sign of waterproofing issues. Outside water could be funneling in through either cracks in your foundation, crawl space vents, doors and hatchways, or the most common catalyst – the ground itself. If you’ve noticed any signs of water in your crawl space, such as groundwater seepage, discolored walls, condensation, rotting wooden floor joists, or efflorescence, your crawl space may need an inspection to find out where the water is coming from and how to prevent it.

If you are experiencing any of these issues, contact Foundation Recovery Systems. Even if the issue may seem minor right now, it will likely turn into a larger, more expensive issue if left untreated. Need an expert opinion? Give us a call today!
