Few Utah homeowners pay attention to the condition of their crawl space, the low-lying area that acts as a buffer zone between their home and the ground below. Besides being prone to moisture, the crawl space attracts various pests. This can create problems for you and cause health issues like asthma and allergies. Moreover, inadequate ventilation in the crawl space can cause your home’s cooling and heating costs to soar.

Fortunately, you can avoid getting hit with a hefty bill by repairing crawl space damage early. Here are some tell-tale signs you have crawl space issues:

1. Moisture

One of the most obvious signs your crawl space needs a repair is moisture. There are several ways that moisture can enter your home’s underlying area, including leaks in the roof, groundwater seepage, insufficient insulation, and poor drainage around the foundation.

Your crawl space may also have water damage if you were hit by a flood. Standing water can damage your home’s structure, so you’ll want to act early. If there’s no way for you to check for stagnant water in the crawl space, you can get in touch with Utah water damage restoration specialists to solve the issue. Leaving crawl space cleanup and waterproofing to the professionals is a wise move.

2. Condensation

With high humidity in the crawl space, you will likely experience condensation. When there is too much moisture in the air, surfaces like joists, floors, and foundations will start collecting it. This can harm the structural integrity of your home.

Condensation can also cause crawl space insulation to become wet, which can lead to further damage. You have to go into the crawlspace to check whether the insulation has fallen or sagged. If it has, a professional who has experience in crawl space repair is the best way forward.

3. Mold and Mildew

The moisture and dampness in crawl spaces provide the perfect environment for mold to grow and thrive. Some signs of mold in a crawl space include musty odors, visible mold growth, and signs of water damage or leaks.

To prevent mold growth in crawl spaces, it is important to keep the area well-ventilated and dry by installing vents or a dehumidifier. Additionally, keep the crawl space clean and clear of debris, as this can provide a food source for mold. If mold is already present, get in touch with a good Utah mold clean-up service immediately for removal.

4. Pests

Did you recently spot cave crickets in or around your home? Although they are not harmful, they can be an indication of a wet crawl space. Other pests to watch for are termites, rodents, black widows, snakes, and silverfish.

Sometimes, pests won’t be visible to the naked eye. But that doesn’t mean your crawl space is free of pest activity. If you spot any droppings or pin-sized holes in wood supports, know that pests are present in your crawl space. Have a seasoned exterminator examine it and repair the spaces enabling these animals to enter.

5. High Energy Bills

High energy bills can indicate issues in the crawl space that may affect energy efficiency. A common issue that can lead to high energy bills is insufficient insulation in the crawl space. If the crawl space is not properly insulated, it can lead to heat loss in the winter and heat gain in the summer, which can increase energy consumption and costs.

There are several ways to insulate a crawl space, depending on the specific condition of the space and your budget. Two popular options are fiberglass batts and spray foam insulation. Here’s a brief description of each:

    • Fiberglass batts are one of the more cost-effective options for insulating a crawl space. You can install them between the floor joists to provide a barrier against heat loss.
    • Spray foam insulation can be used to seal and insulate crawl space walls and floors. This option is more expensive, but it can be more effective in preventing air leaks and controlling moisture.

6. Floor Rot

Various factors can lead to floor rot in a home, but one possible cause is a problem with the crawl space. Excess moisture in the crawl space can seep into the flooring materials and cause rot, especially if the crawl space is poorly ventilated.

Plus, if there is a leak in the plumbing or foundation, the water can seep into the crawl space and eventually cause rot to the floors above. If you notice signs of floor rot, call an expert to address the issue—a timely repair can help you avoid investing in a new wood floor.

7. Efflorescence

Efflorescence is a white, powdery substance that can appear on the walls of a crawl space. It is caused by water coming into contact with certain types of building materials and minerals in the soil. If you detect efflorescence, it is a sign your crawl space needs repair.

To address efflorescence, identify and repair the source of water infiltration: this could be from leaks in plumbing, poor drainage, or a high water table. Once the water issue is under control, clean the walls using a mixture of water and muriatic acid. After cleaning, treat the walls with a water-repellent solution to prevent future efflorescence from forming.

8. Musty Odor

Is there a musty smell arising from your home? It could be a sign of a crawl space that needs your attention.

Mold and mildew growth due to high humidity is the most common reason for musty smells in a crawl space. The mold and mildew thrive in damp and poorly ventilated environments and release a musty odor as they grow. Other factors that can contribute to musty odors include pests, insufficient insulation, and lack of regular cleaning and maintenance.

To get rid of the musty smell, a professional inspection of the crawl space is recommended. Get an expert to address the underlying cause of the odor by removing mold or increasing ventilation in the crawl space.

Final verdict

Whether your home is a few months or a decade old, crawl space damage is a serious threat that requires immediate attention. Look for the above signs and seek professional assistance if you notice them in your home. A proactive approach can help extend the life of your home’s foundation and even add to your property’s resale value.


The low-lying space that serves as a barrier between a home and the ground below is rarely given any attention in Utah. Fortunately, by fixing crawl space damage quickly, you can avoid being faced with a big price. The following are some warning indications that your crawl space has problems.
