While searching for a house, you might have discovered the crawl space amenity. In several regions of the U.S., they are quite popular, particularly in residential constructions. It is because they are more affordable in comparison to full basements. 

But, what exactly is the crawl space? 

Well, it is a hollow area between the ground and the first floor. Generally, it is 1 to 3 feet high, providing enough space for a person to enter by crawling- thus the name crawl space. 

This space helps in elevating the house off the ground. Apart from that, it is also used for containing the “guts” such as heater and air conditioning, insulation, electrical wiring, plumbing, and ductwork.

Not to forget, its condition affects the overall health of the property. Therefore, when purchasing a house with crawl space, you need to pay attention to the following things. 

  • Whether the foundation vents into the space are open or closed? 

While you are inspecting the house’s exteriors, check whether or not the foundation vents into the crawl space are open. Many people leave the area open with the thought that the outside air will help dry out the space and keep moisture under control. 

However, the truth is that outside air adds more moisture to the space- leading to mold growth and wood rot. Therefore, if the space is open, you must close it using vent covers. It will help in blocking the air movement, preventing the area from moisture damage. 

  • Are there any signs of moisture coming through open space? 

Generally, the moist air from outside gets collected on cool surfaces like air ducts and water pipes. It causes corrosion, high humidity in the living area, damp insulation, buckled hardwood floors, and much more. In such a situation, you need to take help from a crawl space encapsulation service that can help regulate the moisture and humidity. They will also help in eliminating the condensation in the duct line. 

Moreover, they can help in preventing unhealthy soil gases such as radon gas from entering the house. In fact, for the betterment of you and your family, it is recommended to book an appointment with encapsulation service providers every season. 

  • Is the crawl space a home for pests? 

It is no secret that a dark and moist place is a home for pests like mice, termites, cockroaches, spiders, and more. Besides these, sometimes larger pests or wildlife such as possums and raccoons can also make crawl space their home. They can damage the insulation, air ducts, and wooden framing of the house. 

Fortunately, a home inspection can help reveal the presence of pests in the building. Sealing all the openings, reducing moisture, and getting pest control can help in protecting the property. Plus, it will give you peace of mind that your family is safe. Nonetheless, you should consult encapsulation service providers to properly evaluate the condition of the space. 


Moisture and pests not only destroy property but can also affect your health. Therefore, you must do all these things beforehand. In case you have already signed the contract, take help from professionals to keep the space clean.
