Your home has many different systems and spaces that all work together to help your family live comfortably every day. Each room in your home serves a purpose, whether or not you think about it daily!
For example, your crawl space plays a crucial role in the function and comfort of your house. However, how often do you think about your crawl space? It is one of those spaces that are “out of sight, out of mind,” yet its presence is incredibly important for your home.
Since you aren’t checking your crawl space for damage or issues regularly, there is a chance that it could be suffering behind the scenes while you are unaware. Heavy rain, drainage issues, and plumbing problems can all spark a moisture issue under your house, leaving your crawl space wet and waterlogged. So, what happens if a crawl space gets wet, and will it dry out on its own?
Let’s dive into the details around crawl spaces and lingering moisture below.
First, it’s important to note whether or not you even have a crawl space! Some homes have basements while others simply have a crawl space under their house. A crawl space is a narrow, unfinished space found underneath a home’s first or main living level. It is usually two or three feet in height and provides access to important systems like your plumbing, electrical, and HVAC equipment.
Crawl spaces also offer a reliable buffer between the ground and your living areas to help maintain your internal temperature and to keep out moisture and pests. Unfortunately, unforeseen situations or damage to your crawl space can lead to issues like water problems and pest infestations.
If any of these situations happen to you and your home, it is important to take action right away to prevent further issues. Many crawl spaces are vented to the outside or have some sort of ventilation, but they are tight areas that don’t experience extensive air movement. Waiting too long to address the water can lead to lasting effects for your entire home.
Once water has entered your crawl space, it starts to seep into porous building materials. Insulation and wood framing will absorb the water, leading to a messy, humid environment. Without proper air movement, it will not dry on its own.
Moist air from the crawl space can travel into your living areas, affecting indoor air quality and comfort.
The longer the water remains, the worse the damage becomes. A persistently wet crawl space can compromise your home’s health and safety.
Moisture causes wood to swell, warp, and eventually rot. Floor joists, beams, and subfloors are at risk. Over time, this can make your floors sag or even compromise your home’s structural integrity.
Mold thrives in dark, damp environments like a wet crawl space. Spores can spread into your home, impacting air quality and triggering allergies, asthma, or other respiratory issues.
Rodents, termites, and insects love damp, undisturbed crawl spaces. If your foundation is compromised, pests can enter and build nests, making the problem even worse.
How can you tell if your crawl space is affected? Your home will give you warning signs if you know what to look for:
Warning Sign | What It Could Mean |
Musty smells from vents | Mold or moisture buildup below |
Sagging or uneven flooring | Structural wood rot in the crawl space |
Visible mold or mildew indoors | Mold migration from the crawl space |
High indoor humidity or condensation | Moist air from below seeping into the home |
Water stains around the foundation | Exterior drainage or seepage problems |
A wet crawl space won’t dry out on its own. That’s where crawl space encapsulation comes in. A moisture barrier is a thick, waterproof liner that seals off your crawl space from the ground and walls to stop water vapor and moisture from entering.
Encapsulation protects your crawl space from future water issues, prevents mold, and reduces pest problems. It also increases energy efficiency by maintaining stable temperatures below your home.
So, what happens if a crawl space gets wet? The answer: structural damage, mold, humidity, and pests. It won’t dry out naturally and should never be ignored.
