Problems in your crawl space won’t stay confined below your house. You will notice various symptoms throughout your home, and seeking professional repairs right away is important. Dry Pro can help.

Schedule Free Inspection

Unless you’re playing an intense game of hide-and-seek with the kids, you have no reason to go  underneath your house and into the crawl space. Why would you? After all, many crawl spaces are dark and dingy, and who knows what’s lurking in there. 

True, you should not venture into this area of your Charlotte or Hickory home because it is both dangerous and delicate. However, it’s important for you to be aware of your crawl space’s condition. It impacts the rest of your house and even your family’s quality of life. 

With the help of our team at Dry Pro Foundation and Crawlspace Specialists, you can have a safer and healthier crawl space and home. Below, we’ve compiled a list of the most common problems you will notice throughout your North Carolina home that point to crawl space issues and the need for repair. Keep reading to learn more about what problem signs you should look out for, the effects of an unrepaired crawl space, and how Dry Pro can help. 

Here are the top 7 signs that your crawl space needs repair:

  • Mold
  • Musty Odors
  • Pests
  • High Energy Bills
  • Sagging Floors
  • Drywall Cracks & Nail Pops
  • Sticking Windows & Doors


Mold grows and thrives in your crawl space with the presence of water, humidity, and wood. 
Because of the stack effect, mold spores will become airborne, travel up into the rest of your house, circulate in the air, and mold can start growing in damp areas like bathrooms and kitchens.  
Mold also has a distinct odor and comes in many colors (yellow, white, pink, green, black, and brown). 

Musty Odors

Musty, unpleasant odors that don’t seem to go away after thoroughly cleaning your house can linger because of a nasty crawl space. Again, because of the stack effect, these noxious nuisances will circulate to your main living area.  
Some smells that can overwhelm your home include mold, pest waste, wet insulation, and rotting wood. 


Many pests love damp, moldy environments like crawl spaces. They also can find their way into your main living area.  
If you notice an uptick in bug and pest presence, there could be underlying issues in the crawl space. 

High Energy Bills

If you’ve noticed your energy bills seem higher than normal, it could be more than a simple price increase.  
Your HVAC system could be working overtime to create a comfortable temperature in your home if your crawl space has open vents that let in hot and humid summer air, as well as cold winter air. 

Sagging Floors

Water, humidity, mold, wood rot, and pests can attack the wooden supports and floor joists in your crawl space.  
When the structural integrity of these underlying supports is compromised, they will start to bend under the weight of furniture and people. The floors will sag and feel uneven, soft, and bouncy. 

Drywall Cracks & Nail Pops

Sagging floors can be accompanied by other signs that point to foundation damage within your crawl space.  
If your crawl space foundation is settling and uneven, you’ll notice cracks in your interior drywall on upper floors, most notably diagonal cracks stemming from window and door frames. Round nail pops in drywall are also common. 

Sticking Windows & Doors

Similarly, when your floors start to sag, especially close to a wall, the windows and doors along that wall can become difficult to properly open and shut. They can stick in their frames and doors can swing open or slam shut independently.


Typically, having professional crawl space encapsulation solutions installed is not covered by homeowners insurance. Insurance companies generally look for an event that causes problems like a plumbing leak. 

However, insurance may cover some work if your policy has a mold rider. It’s best to double check your policy with your agent. Regardless, crawl space repair and encapsulation is a worthwhile investment that is not only an immediate fix, but something that will prevent future damage and insurance claims. 

To keep excess water away from your crawl space, you can extend your downspouts away from your house.  

If you can readily see into your crawl space, you can place a digital weather station inside to monitor temperature and humidity. You can also grab any leftover construction materials to help keep the area free of debris. 

However, we do not recommend that you go into your crawl space to inspect it or install any repairs because this is a delicate and dangerous area.  

To ensure your crawl space is permanently repaired and protected, it’s best to leave all installations to highly trained experts.

Our team at Dry Pro has been fixing crawl spaces around Charlotte and Hickory for more than 20 years. We stand by our work because it will keep your home safe and healthy for years to come.

What Happens If You Don’t Act?

If you don’t fix your crawl space issues in a timely manner, these are the possible consequences: 

Let’s examine each of these points more in-depth

Poor Health & Quality of Life

Almost 50% of the air in your home comes from the crawl space, so you could also be breathing in dust, pest waste, and other hazards.  

While mold originating from crawl spaces is not always toxic, it can trigger severe reactions in sensitive people and pets including asthma, allergies, and other respiratory problems. Nobody wants to always be coughing, sneezing, and constantly feeling sick.  

Worsening Structural Problems

Festering water intrusion, moisture, wood rot, and termite damage compromises your crawl space and home’s structural stability.  

Anyone, especially those with mobility issues, can trip on uneven floors, and soft wood could eventually give way and lead to a collapse. All these issues put your family’s physical safety at stake. 

Decreased Home Value

While it’s possible to sell a house with crawl space and other issues, any known damage needs to be documented when you fill out the State of North Carolina Residential Property and Owners’ Association Disclosure Statement.  

However, crawl space problems that lead to issues like sagging floors and mold growth can cause home buyers to take notice. This can make it difficult to sell your house, as well as lower your home’s value.
