Crawl Space Repair

Crawl Space Repair & Insulation Services in Greater St. Louis

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

In this video, learn how to solve home comfort problems caused by an unsealed, uninsulated crawl space.

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.

Dr. Energy Saver St. Louis 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 1-877-622-2308 or contact us online to get started with a free crawl space insulation estimate in St. Louis, Florissant, Ballwin and the nearby areas.

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.

Before and After
  • Crawl Space Insulated with SilverGlo in Rochester, IL
    Before
    Crawl Space Insulated with SilverGlo in Rochester, IL
    After

    Don M. was having trouble keeping his Rochester, IL home comfortable. He had drafts coming into his home from the crawlspace. His energy bills were high from needing to run his air conditioning and heating much longer to get less change in the temperature of his home so he called Woods Basement Systems. Woods recommended insulating and encapsulating his crawl space.

    Woods installed SilverGlo over the foundation walls and rim joists in the crawl space. SilverGlo is a graphite-infused rigid foam insulation that has a reflective surface to create a radiant barrier that reflects heat back into the crawl space. SilverGlo is waterproof and mold-resistant so it also prevents moisture from entering into the crawl space through the foundation walls. It seals drafts out and heated and cooled air in the crawl space.

    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.

    Insulated Knee Wall in O'Fallon,IL
    After

    A knee wall space is created when a finished room is built within a sloped roof. Often, these walls are “insulated” using fiberglass batting. Since fiberglass does not stop air flow, the insulation does next to nothing to air seal and insulate----causing rooms sharing walls with knee walls to be very uncomfortable. Dr. Energy Saver St. Louis air sealed and insulated this O'Fallon, IL homeowner’s knee wall with SilverGlow insulation. Now, inside air can’t get out of the house through the knee wall spaces and outside air can’t get in. This bedroom is comfortable again!

    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.

  • Insulating Attic Hatch in St. Peters, MO

    The average attic hatch is usually poorly insulated, if insulated at all. While some homeowners may attempt to insulate this hatch area with a bat of fiberglass insulation, this is not the best way to air seal or insulate it. Air transfers right through the bat much like air passes through a furnace filter. Dr. Energy Saver St. Louis air seals and insulates attic hatches with our exclusive SilverGlow insulation, which insulates the hatch to an R-20. Air cannot pass through the SilverGlo insulation---coupled with an air seal using one-part foam, the attic hatch area is now sealed tightly.

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.
