Repairing and Encapsulating a Crawl Space in a Cincinnati, OH, Home

In a 1980s home in Cincinnati, OH, persistent crawl space moisture was leading to insulation failure, high humidity, and structural concerns. Uneven floors and damp conditions left the homeowners feeling frustrated and concerned about long-term damage.
Ohio Basement Authority stepped in with a full encapsulation and stabilization solution.

Before Crawl Space Encapsulation:

Moisture, Mess, and Structural Stress
The homeowners had dealt with moisture-related issues in their crawl space for years. During the inspection, the Ohio Basement Authority team found water-damaged insulation hanging from joists, significant debris buildup, and high humidity levels throughout the space. These conditions were contributing to sagging floors above and increasing the risk of long-term structural and air quality problems. A solution was needed quickly to prevent the situation from worsening.
After Crawl Space Encapsulation:

Insulation and Structural Reinforcement
The crew began by removing all debris and deteriorated insulation, creating a clean slate for repair. They installed ExTremeBloc™ wall insulation panels for superior thermal and moisture protection, and sealed rim joists with spray foam to reduce air leakage. To reinforce the home’s structure, the team installed IntelliJack™ stabilizers and supplemental support beams—repairing floor joists where necessary.

Encapsulation and Moisture Control
Next, a full waterproofing system was installed, including perimeter drainage and a sump pump outfitted with FreezeGuard™ attachments to protect against winter backups. The team then encapsulated the crawl space using CrawlSeal™, a heavy-duty 20-mil vapor barrier laid over drainage matting to improve both drainage and barrier durability. Vent covers sealed exterior openings, and a commercial-grade dehumidifier was added to regulate humidity and prevent mold growth.
