If your crawl space is vented, uninsulated, doesn’t have enough insulation, or has old fiberglass batts, Ohio Basement Authority can solve your crawl space insulation needs.

    Unhealthy Crawl Spaces in Croton, OH, are Properly Insulated and Sealed

    A homeowner in Croton, OH, wondered why his floors were always cold in the winter, and why he was noticing more mice and mold around his house. He rarely goes into the multiple crawl spaces underneath his home, so he didn’t realize the problems were coming from these areas.

    He contacted Ohio Basement Authority after learning more about our company online, and Inspector Brendan Kent completed a thorough evaluation at the 95-year-old home. In the separate crawl spaces, Brendan found moldy and failing insulation, debris, and open vents.

    Not only are these conditions unhealthy for the crawl spaces, they also affect the health of the rest of the home. They can also lead to health problems like asthma and allergies, or make these issues worse.

    Brendan then proposed several permanent crawl space repair options. While the homeowner received repair estimates from other companies, he liked our methods the best.

    One of our expert crews first took great care to remove the insulation and debris from each crawl space, then they placed sheets of insulation on the floors. The crawl spaces were then completely encapsulated in CrawlSeal liner, and ExTremeBloc panels were installed on the walls. All of these products help insulate the crawl spaces and improve their appearance and functionality.

    Spray foam insulation was added to the crawl space rim joists for extra protection, vent covers were installed outside the home to seal the crawl spaces from outside air and pests, and a dehumidifier was installed in the basement to control humidity.

    The owner was excited to have these projects completed so his home will be a healthier and more energy efficient living environment for many more years to come.

    CrawlSeal Encapsulation Improves Health, Appearance of a Crawl Space in Hilliard, OH

    Homeowners in Hilliard, OH, were pleased to have their sump pump and exterior drainage system updated by Ohio Basement Authority in recent years. They also welcomed having return visits with our service techs who performed annual check-ups and maintenance to keep the systems running smoothly.

    During a recent annual maintenance appointment, one of our service technicians noticed a crawl space access near the back of the basement. As he looked inside and further investigated the crawl, he found debris and failing insulation and floor liner. He recommended having the crawl space encapsulated by one of our crews, and the homeowners were eager to have this project completed as well.

    Foreman Milton Castro led his crew in first removing the nuisances from the crawl space. The dirt and gravel crawl space floor was evened out, and thick drainage matting was placed on the floor to enhance the durability of the encapsulation system. The crawl space was then sealed with CrawlSeal liner. Similar to swimming pool liner, CrawlSeal is thick and durable. It acts as a moisture and vapor barrier, helps insulate the crawl space, and improves the appearance of the crawl space. This encapsulation project also has helped create a more functional area that can be used as storage.

    Along with encapsulating the crawl space, we also installed a dehumidifier in the basement to help improve the health and air quality of the home. The compact but powerful and energy-efficient model cleans and filters the air, controls moisture and humidity, and helps reduce odors and the potential for mold growth.

    The homeowners are happy repeat customers who are pleased to have a healthy living environment.

    Crawl Space Encapsulation & Insulation in Plain City, OH

    Homeowners in Plain City, OH, have lived in their house for 22 years, and they wanted to create a healthier storage area in their crawl space.

    While their crawl space did not leak or cause energy penalties, they noticed problems with mice in the past.

    After removing the older insulation and matting, one of Ohio Basement Authority's expert crews encapsulated the crawl space with CrawlSeal liner. This isolates the home from the earth and pests. Drainage matting was placed under the liner to enhance durability, and ExTremeBloc insulation panels were installed on the walls.

    Both the walls and floor are now insulated to save the most money. These products also meet the homeowners' goals of controlling earth moisture, saving energy, and creating a cleaner crawl space.

Problems with vented crawl spaces and fiberglass batts

Decaying fiberglass insulation

Wet fiberglass batts hanging from the floor joists is a common crawl space problem

While fiberglass batt insulation is the cheapest and easiest DIY choice for insulating the crawl space, there are several problems with using fiberglass batts in a vented crawl space:

  • Fiberglass insulation absorbs water and loses its R-value when wet
  • Air passes through fiberglass batts, contributing to uncomfortable rooms upstairs, cold floors, and high energy bills
  • Wet, dirty fiberglass batts support mold growth

Crawl spaces with insulated foundation walls are warmer and drier than crawl spaces with insulation between the floor joists.

Our crawl space insulation process

At Ohio Basement Authority, we specialize in solving crawl space insulation problems. We don’t just winterize crawl space pipes or vents, but instead seal and winterize your entire crawl space foundation to bring your plumbing and heating system inside your home’s conditioned space. Here’s how our process works:

  • Air seal and insulate the rim joist: A tremendous amount of heat is lost through the rim joist that rests on your crawl space foundation. We prevent frigid air from leaking in by sealing gaps around the perimeter of your foundation. Then we reduce conductive heat loss by insulating the rim joist with foam insulation.
  • Insulate crawl space walls with rigid foam: We install high-performance ExTremeBloc™ rigid foam insulation against the crawl space walls. ExTremeBloc™ does what fiberglass can’t: stop air leaks, never lose R-value, and never absorb or be damaged by moisture.
  • Seal & insulate the crawl space floor: In colder climates, we recommend installing foam insulation on the crawl space floor. This specialized flexible insulation is then covered with our CrawlSeal® moisture barrier that completes the sealing process. The crawl space is now isolated from outside conditions.
