Comprehensive Crawl Space Solution by Midwest Foundation Repair, A Case Study
Challenge
Alexandria, a dedicated sheriff's deputy in Iowa, was faced with a challenging situation. Her crawlspace was perpetually wet, and the absence of proper drainage aggravated the problem. The high water table and lack of encapsulation contributed to the continuous moisture, leading to mold growth and a potential health hazard. Furthermore, Alexandria's concerns extended beyond the structural issues; she wanted to create a safer and healthier environment for her four children. Encapsulating the crawlspace not only promised to address these challenges but also increased the usable space within her home and enhanced its resale value.
Problems With Dirt Crawl Spaces
Prevalence of Vented Dirt Crawl Spaces: Surprisingly, over 250,000 new homes are constructed each year with dirt crawl spaces, and when considering existing homes, the number reaches a staggering 27 million. Vented crawl spaces are a common design feature in many regions, particularly in the Southeastern United States. Despite their prevalence, these crawl spaces pose significant challenges and potential hazards to homeowners.
Building Code Limitations: The building code requirements for vented crawl spaces contribute to the problem. Building regulations often mandate the installation of vents, assuming that they will allow for proper ventilation and moisture control. However, this approach fails to acknowledge the negative consequences that come with vented crawl spaces, such as increased humidity levels and moisture intrusion.
High Humidity and Mold Growth: Crawl spaces with block walls, similar to Alexandria's, are particularly susceptible to moisture-related issues. These crawl spaces often have porous walls with imperfect mortar joints, allowing water to seep in easily. The lack of exterior footing drains and the absence of damp-proof or waterproof wall coatings further exacerbate the problem. The continuous presence of moisture creates a favorable environment for mold growth, leading to potential health risks for residents and structural damage to the home.
Impact on Air Quality: The stack effect, a natural airflow phenomenon in homes, plays a significant role in crawl space issues. It draws humid air from the crawl space into the living areas, leading to a range of problems. Excess humidity can result in musty odors, condensation on windows, and even frost buildup. The compromised air quality can trigger respiratory issues, aggravate asthma and allergies, and impact the overall health and comfort of the home's occupants.
Increased Energy Costs: Vented crawl spaces contribute to higher heating and cooling costs. The presence of excess moisture and the lack of insulation in these spaces make it challenging to maintain a consistent indoor temperature. As a result, homeowners end up using more energy to heat or cool their homes, leading to increased utility bills.
Structural Damage: Moisture intrusion and excessive humidity in crawl spaces can cause significant structural damage over time. Wooden floor joists, beams, and subflooring are particularly vulnerable to moisture-related issues. Rot, decay, and wood-boring insect infestations can compromise the structural integrity of the home, resulting in costly repairs and potentially endangering the safety of its occupants.
Resale Value and Home Aesthetics: Crawl space problems can also negatively impact the resale value of a home. Potential buyers are often deterred by homes with crawl space issues, as they are aware of the associated maintenance costs and potential health risks. Furthermore, visible mold, musty odors, and structural damage can detract from the overall aesthetics of the home, making it less appealing to prospective buyers.
By understanding the extensive problems associated with crawl spaces and the potential risks they pose, homeowners like Alexandria can take proactive steps to address these issues, ensuring the health, safety, and long-term value of their homes.
Problem Diagnosis
When Alexandria reached out to us, System Design Specialist Kevin F. was assigned to her case. During the free consultation, Kevin meticulously assessed the situation, taking into account the wet and muddy state of the crawlspace and the absence of proper drainage. With his expertise, Kevin could identify the specific problems that Alexandria's home faced, ensuring a comprehensive and tailored solution. The following is what Kevin prescribed: crawlspace encapsulation to protect the home from ground moisture, installation of an adequate sump pump, and a Sanidry Sedona system to reduce humidity and purify the air.
Solution
Crawlspace encapsulation is a proven and effective solution to mitigate the problems associated with vented dirt crawl spaces. It involves sealing off the crawl space from the outside environment and implementing a comprehensive moisture control system. By creating a conditioned space, encapsulation helps maintain stable humidity levels, prevent moisture intrusion, and improve indoor air quality.
Vapor Barrier Installation: One of the key components of crawl space encapsulation is the installation of a high-quality vapor barrier. This barrier is typically made of thick, durable material such as polyethylene or reinforced plastic. It is placed on the crawl space floor and extended up the walls, effectively creating a moisture barrier that prevents ground moisture from entering the space.
Sealing Foundation Vents: Encapsulation involves permanently sealing off foundation vents that were originally intended for ventilation. These vents, which contribute to moisture and humidity issues, are closed to prevent outside air and moisture from entering the crawl space. By eliminating the entry points for excess moisture, encapsulation helps maintain a dry and controlled environment.
Insulation and HVAC Integration: Encapsulation also includes insulating the crawl space walls and sometimes even the floor above. This insulation helps to regulate temperature and reduce energy costs by preventing heat loss or gain. Additionally, HVAC (Heating, Ventilation, and Air Conditioning) systems can be extended to include the crawl space, providing conditioned air and further enhancing the overall comfort and efficiency of the home.
Dehumidification and Moisture Control: To address the issue of excess moisture, encapsulation systems often incorporate dehumidifiers or other moisture control mechanisms. These devices help maintain optimal humidity levels in the crawl space, preventing mold growth, musty odors, and structural damage. By effectively controlling moisture, encapsulation improves air quality and protects the home's overall integrity.
Pest Control Measures: Encapsulation acts as a barrier against pests and insects that can infest crawl spaces. The sealed environment prevents easy access for rodents, termites, and other pests, reducing the risk of damage to the home's structure. This aspect of encapsulation helps homeowners protect their investments and avoid costly pest-related repairs.
Long-Term Benefits and Cost Savings: Investing in crawl space encapsulation provides numerous long-term benefits. By addressing moisture issues and improving air quality, encapsulation promotes a healthier living environment for occupants. It also helps protect the home's structural integrity, reducing the likelihood of expensive repairs in the future. Furthermore, encapsulation can lead to energy savings by reducing heating and cooling costs, making it a cost-effective solution in the long run.
Increased Home Value and Marketability: Encapsulating a crawl space can significantly enhance a home's value and marketability. Potential buyers recognize the benefits of a properly encapsulated crawl space, including improved air quality, energy efficiency, and protection against moisture-related issues. Homes with encapsulated crawl spaces often command higher resale values and attract more interested buyers.
By considering these facts about crawl space encapsulation as a solution, homeowners like Alexandria can make informed decisions to improve the conditions of their crawl spaces, leading to a healthier, more energy-efficient, and valuable home.
The Results
After the completion of the crawl space encapsulation and other measures, Alexandria experienced a remarkable transformation in her home. The persistent moisture problems that plagued her crawl space were effectively resolved. With a dry and encapsulated crawl space, Alexandria's basement became free of mold growth, unpleasant odors, and excess humidity. The increased usability of the crawl space allowed for additional storage, further improving the functionality of her home. Moreover, Alexandria's concerns about the health and well-being of her children were addressed.
