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

Crawl space with plastic vapor barrier on floor and supports; bucket and pipes are visible under wooden beams.

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. Over eight days, the team removed damaged materials, installed advanced insulation and waterproofing systems, and reinforced the structure with IntelliJack™ supports. The result: a dry, stable crawl space and a home protected from future moisture issues.


The Challenge

  • High humidity and failing insulation in the crawl space
  • Uneven floors and signs of structural weakening
  • Need for a long-term moisture and stability solution

The Solution

  • CrawlSeal™ 20-mil vapor barrier and drainage matting
  • ExTremeBloc™ wall insulation and spray foam for rim joists
  • IntelliJack™ stabilizers and supplemental beam installation
  • Sump pump with FreezeGuard™ and dehumidifier system

The Impact

  • Fully encapsulated, dry crawl space
  • Improved structural stability and air quality
  • Long-term protection from water intrusion and humidity

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:

Crawl space with plastic vapor barrier covering the floor and plumbing pipes overhead.

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.

I had an incredible experience with Ohio Basement Authority. I needed significant work done in my basement to help stabilize the floors and support lifting the house over time, and the entire process exceeded my expectations. Scot, the sales rep, was outstanding. His communication, clarity, and ability to walk me through the “what,” “why,” and “how” made a huge difference. As a homeowner, I felt informed and confident every step of the way. He also set the project up seamlessly for the installation team. Daniel, the foreman, and his crew were equally great. He was very communicative, clearly explained what would be done over the two days, and kept me updated throughout the process. The team worked efficiently, stayed on schedule, and did a great job minimizing disruption. They were also very respectful of the space and made sure everything was cleaned up afterward. Overall, the team was professional, knowledgeable, and easy to work with. Their communication, efficiency, and attention to detail really stood out. I would highly recommend working with them, quality work!
