Crawl Space Insulation Services in St. Louis, Springfield, St. Charles & Nearby

Crawl space insulation can improve your home's comfort and efficiency

Fiberglass dripping off of the ceilings of a Decatur crawl space

Fiberglass insulation in a crawl space tends to soak up moisture and humidity, growing mold and eventually causing it to "drip" off the ceiling.

Crawl spaces are typically uninsulated and unsealed spaces that tend to soak up the natural cold of the earth around your home. This leads to cold floors and rooms above the crawl space, energy loss, and mold problems. For homeowners with ductwork, pipes or other utilities in the crawl space, energy efficiency problems will be worsened.

Woods Basement Systems, Inc. can help solve all these problems and more in your home with crawl space repair and encapsulation. We offer moisture and mold resistant crawl space insulation materials that are designed to eliminate energy loss and help create a more comfortable home. Call us today at 1-844-204-8198 or contact us online to get started with a free crawl space insulation estimate in St. Louis, Springfield, St. Charles and the nearby areas.

    Jana V. of Louisiana, Missouri discovered that her home's crawl space was collecting water. She did not want any rotting or mold growth to occur, so she called Woods Basement Systems for help.

    Design specialist James F. assessed the situation and decided that a CleanSpace encapsulation system would solve the water leakage. He also decided that insulation of the rim joists would help the homeowner. Foreman Reginald B. headed to the home to get the job started. The crawl space was insulated and sealed with a spray foam. The spray foam, pictured above, was installed in the joists where the wall of the crawl space meets the ceiling of the crawl space. 

    Jana V. no longer has to worry about a wet crawl space, or any energy inefficiency. She now has an insulated and waterproof crawl space.

    In O’Fallon, Illinois homeowner Nathan T. wanted to seal and waterproof his crawlspace. He began to notice that the floor above the crawlspace was sinking in and a smell coming from the space. He heard from a friend who had gotten his crawlspace sealed and waterproofed by Woods Basement Systems that he is now able to use the space for storage and it no longer effects the home above. Because of this, Dan finally decided to call Woods.

    We sent our foreman Dwayne M. and his team out to the home to seal the crawlspace once and for all. They used our patented CleanSpace liner, which is a thick durable liner (similar to a pool liner) to cover the flooring and walls of crawlspace. Now, Dan has peace of mind knowing his crawlspace is sealed and waterproofed.

    William J. from Eureka, Missouri was looking for a way to clean and brighten up his crawlspace. Crawlspaces like the one in William's home are exposed to the earth, which means they are exposed to mold, fungus, rot, and critters. A home with a dirt crawlspace costs more energy to heat and cool, and more energy costs more money.

    Concerned, William decided to call Woods Basement Systems to fix his crawlspace problem. Foreman Micheal Rebenstorff installed a CleanSpace Liner to the floors and walls of William's crawlspace. The CleanSpace Liner has an antimicrobial additive manufactured to the material, which prevents mold growth on the liner. Williams crawlspace is now sealed from the earth, making his home easier to cool and heat.

  • Cleanspace and Spray Foam in Ballwin,MO

    Cleanspace and Spray Foam in Ballwin,MO
    After

    A dirt crawl space under a home can lead to unending problems. The earth has very high humidity in the soil. This water vapor moves easily into the crawl space and upwards into the house environment. Mold thrives and reproduces by producing airborne spores by the millions and some molds are toxic. Insects and critters of all kinds love the damp environment as well. The CleanSpace encapsulation system completely isolates your home from the earth. This dramatically reduces the humidity level in the air which, when combined with sealing outside air and dehumidification, will eliminate mold growth and rot from your crawl space and make the whole house a healthier environment.

    The detail between the foundation wall, the sill plate, the rim joist, and the sub flooring allows for significant air leakage from the outside...especially when pipe wire penetrations are added. It is also this rim joist area that is often poorly insulated. Even when your rim joist is insulated with fiberglass bats, the outside air will still leak in through the bats, because this form of insulation acts as a filter. Spraying expanding foam insulation on the inside surface of the rim joist, to cover the sill plate down to the top of the basement wall, not only seals all air leaks very effectively, but it insulates as well.

Signs of crawl space insulation problems

  • The floor above the crawl space is unpleasantly cold in wintertime
  • During cold weather, you have to keep the heat going nearly all the time to be comfortable in rooms directly above the crawl space
  • Mice or other pests have taken up residence in fiberglass insulation installed between joists in the crawl space
  • Fiberglass batt insulation has fallen out of place from between floor joists in the crawl space
  • The crawl space smells moldy, has visible signs of mold, and/or is damp all the time

Many homes have the wrong type of crawl space insulation

The old-fashioned way to insulate a crawl space was to install fiberglass batt insulation between joists and vent the crawl space so outside air could circulate beneath the house. Unfortunately, this combination usually leads to the problems listed above. Fiberglass insulation doesn't respond well to the moist conditions that can be found in a crawl space.

The cotton-like material absorbs moisture, gets soggy, compresses and loses R-value. Fiberglass batts often end up on the crawl space floor in a soggy mess. The main advantage of fiberglass insulation — low cost — is totally negated when the material ceases to perform its main function.

Benefits of insulating your crawl space with rigid foam

  • Stable and reliable: Unlike fiberglass insulation, rigid foam won't compress, fall out of place or lose its R-value over time. It's a "once-and-done" improvement.
  • Effective air sealing: When joints between foam panels are taped, rigid foam stops air leaks that can waste energy. Fiberglass insulation can't stop air movement.
  • Moisture-proof: Rigid foam won't absorb moisture or be damaged by it.
  • Unfriendly to mold: Mold can't take hold on rigid foam because it contains no organic food source and it doesn't hold moisture.
  • Better ductwork performance: Ducts located in the crawl space benefit from rigid foam installed against crawl space walls.

Rigid foam panels outperform fiberglass in the crawl space

Silverglo Insulation

Long-lasting. Rigid foam insulation can't be damaged by moisture and won't degrade in appearance or R-value over time. In a crawl space, it's usually installed against the interior face of foundation walls.

Rigid foam insulation performs much better than fiberglass in a crawl space. This type of insulation is manufactured in panels of different thicknesses. Installers cut the panels to fit against the interior face of crawl space foundation walls. Panels are secured with adhesive or mechanical fasteners.

We typically insulate crawl space walls with
foam board insulation. This brings the crawl space inside the building envelope, which improves overall home energy performance. This will also help make rooms above the crawl space more comfortable and can help lower heating and cooling bills.

Although rigid foam insulation costs more than fiberglass insulation, it's less expensive when you consider that you'll never have to clean up or redo a mess of damaged, ineffective installation. Rigid foam will deliver the same performance and benefits in 15 years as it does on day #1.

TerraBlock™ insulation is flexible and strong for use on crawl space floors
