Know the symptoms of a damaged crawl space and get solutions from NSquare

Crawl spaces are prone to issues with water damage, mold growth, or pest infestation, and these issues can impact the air quality inside your home. Crawl spaces promote air circulation that can sometimes seep into your home through the floorboards. If the air quality in your crawl space is low, it’s likely to cause air quality issues inside your home.

It’s easy to ignore your crawl space since it’s not technically inside your home, but it’s important to keep up with maintenance to prevent any issues from getting worse over time, and they will, if left untreated. If you’ve ignored your crawl space for quite some time, it’s a good idea to look out for certain symptoms that could lead to more serious issues.

Symptoms of Crawl Space Damage:

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 Florida 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. This 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 Crawl Space

Bugs and other pests are unwanted in general, but vented, dirt crawl spaces will unfortunately let critters in from time to time. If you notice an increase in unwanted visitors, however (more than the occasional creepy crawly), 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 permanently. If your crawl space is clean and dry, critters won’t find any reason to live there. And if its sealed, they can’t get in. Don’t take bugs lightly. They only mean one thing for your crawl space, and that’s bad news!

Spotting early symptoms of crawl space issues can save you time, money and headaches in the long run. It’s important to regularly check your crawl space for any of these symptoms to avoid further impact on the air quality inside and structural integrity of your home. Need a second opinion?
