Before Crawl Space Encapsulation:

Foundation Cracks and Settlement
The home showed signs of foundation settlement caused by Tennessee’s expansive clay soil and temperature fluctuations. These conditions put pressure on the foundation, leading to structural stress, which caused foundation cracks.

Crawl Space Moisture
Moisture intrusion and inadequate insulation compromised the crawl space environment. The old cellulose insulation had deteriorated, contributing to poor indoor air quality and increasing the risk of mold growth and wood rot.
After Crawl Space Encapsulation:

Stabilized Foundation
To address signs of settlement, AFS installed 10 push piers at depths ranging from 4 to 18 feet beneath the foundation walls. This system permanently stabilized the foundation, prevents further movement, and protects the home’s long-term integrity.

Moisture-Controlled Crawl Space
A complete encapsulation system, including a vapor barrier, crawl space door repair, and dehumidifier, was installed to seal out moisture and control humidity levels. These upgrades created a clean and dry crawl space environment, reducing the risk of future water damage.

Improved Indoor Air Quality
Removing the deteriorated cellulose insulation and sealing the crawl space helped improve the air quality throughout the home. The addition of a dehumidifier further reduced excess moisture, lowering the risk of mold growth and contributing to a healthier living environment.

Crawl Space Encapsulation FAQs
Encapsulation seals the space from external elements, reducing the need for frequent repairs and keeping the crawl space dry and clean.
While crawl space encapsulation offers many benefits, it’s important to weigh a few factors. The initial cost can be high, but it’s offset by long-term energy savings and avoided repairs. You’ll need to commit to annual maintenance to ensure the system remains effective. Proper pre-encapsulation cleaning is crucial to prevent potential gas buildup from decaying organic matter. Despite these considerations, encapsulation typically improves home comfort, energy efficiency, and long-term value for most homeowners.
While DIY crawl space encapsulation may seem cost-effective initially, it can actually end up costing you more in the long run if not done properly. It’s best to leave it to professionals with the experience and knowledge to ensure a successful encapsulation.
