Standards in home building have changed a lot over the years. Better energy efficiency, greater severe weather tolerance and non-toxic building materials are just a few of the perks that modern homes enjoy today thanks to updates to the International Residential Code (IRC). In fact, it’s becoming increasingly popular for homebuilders to go above and beyond IRC requirements to include environmentally friendly features like fresh air, natural light and eco-friendly building materials.
Moisture and Humidity in Your Crawl Space
Improved home building codes, best practices and scientific advancements have shown us how to build crawl spaces that make homes cleaner, healthier and much more energy efficient. However, building codes here in Nebraska, Iowa and Kansas allow both vented and closed crawl spaces, so how do you know what’s right for your home? The answer is all in the moisture and humidity levels. And because we all know how hot and humid summers in the Midwest can be, it’s likely that a closed, or encapsulated, crawl space is the best solution for your home.
Common Crawl Space Problems
It’s obvious to homeowners with basements that water intrusion is a problem. But why does water matter in a home with a dirt floor crawlspace? Read below to learn about how moisture, humidity and chemicals can cause problems for your whole home.
Roof runoff and improper grading can allow water to collect and enter your crawlspace through cracks in the foundation walls.
Mold and fungi: dampness can breed mold and fungi that rises with warm air into your home living space.
Structural damage: high humidity and moisture can cause wood rot and degrade building materials.
Radon can rise through the soil, into your crawlspace and ultimately into the living space.
Poor air quality: Moisture and humidity lead to musty odors, allergens and dust, and rises to enter the living space.
Bugs and critters are attracted by the moisture and humidity and can cause wood rot and structural damage.
Rising energy costs: Vented crawlspaces let in humidity in the summer and cool air in the winter, leading to higher heating and cooling costs.
Symptoms of a Crawl Space Problem
If you experience the following symptoms, your crawlspace could have structural damage, mold or air quality issues.
Foul Odors in the Home
Drywall Cracks in the Interior
Heightened Allergies or Asthma Symptoms
The Benefits of an Encapsulated Crawl Space
Sealing your crawlspace heavily reduces moisture and humidity levels, leading to:
Improved air quality – no musty odors, reduced dust and allergens
Greater durability and reduced risk for structural damage
No bug food, thus no bugs
Increased storage space for you home
15-20% savings in energy costs
Now that you know more about the difference between encapsulation and vented crawl spaces, you may have an idea of what’s best for your home. It’s clear that unsealed crawl spaces allow mold to grow, attract bugs and critters and contribute to poor air quality – not to mention the potential for structural damage and wood rot. So, what can you do?
Watch for symptoms of a crawl space problem.
You may notice musty smells, heightened allergies or asthma symptoms (especially in the winter), drywall cracks inside your home or uneven floors.
