Crawl Space Insulation

Crawl Space Insulation Contractor Near Gaithersburg, Bethesda, Rockville

Keep your home comfortable & energy bills low with the right insulation

In this video, Dr. Energy Saver solves home comfort problems caused by an unsealed, uninsulated crawl space. Watch to see how to make your crawl space more energy efficient!

Crawl spaces are shallow structures installed directly into the dirt under your home. As such, they tend to soak up the natural cold of the earth around your home and transfer it into the air in your crawl space.

If you have utilities in your crawl space such as your water heater, furnace, or hot water pipes, your energy bills will suffer. The fluctuation in temperature will force your heating and air conditioning systems to work harder, causing your energy costs to rise.

For your crawl space insulation to perform like it should, it's essential to install the right type of insulation, the right amount of insulation, and use the correct installation technique.

At Dr. Energy Saver Central Maryland, we can improve the condition of your crawl space and the living space above with products that are durable, long lasting, and made especially for the crawl space environment.

    Encapsulated Crawl Space in Edgewater, MD

    Before and after Encapsulated Crawl Space in Edgewater, MD: Millions of homes were built with vented dirt crawl spaces. Now building scientists are realizing that this was a huge mistake by noticing all the problems they are causing. In the winter the old crawlspace vents are letting cold air into the house. In the summer the crawlspace was allowing warm humid air to be created causing a bad smell throughout the house because of the mold that was growing in the crawl space. The crawl space was encapsulated with a liner on the walls and floors. Also the walls were insulated with SilverGo with reflective radiant barrier face.

  • Crawl Space Encapsulation in Annapolis, MD
    Crawl Space Encapsulation in Annapolis, MD

    It is obvious that this Annapolis, MD crawlspace is in desperate need of some attention. One of our home energy comfort specialists was called out to the home because the homeowner was experiencing cold floors and a smelly crawlspace with rodents. Upon inspection, we found that the insulation in the vented crawlspace was wet from humidity coming off the ground, and the plumbing systems and ventilation pipes were all located in the crawlspace.  To remedy this problem, we air sealed and insulated the entire space using our CleanSpace crawlspace Encapsulation 20 mil liner with Silverglo insulation on the walls. This was used to successfully separate the home from the earth. Now, thanks to the Dr. Energy Saver Central MD production team, we have air sealed every hole, crack and crevice, ensuring that no other air leaks will happen in the future. The house is now existing over a nice clean environment that is humidity controlled, with no more musty smell or cold temps! The duct work is now ventilating the house with fresh clean air. This upgrade will save on heating and cooling costs making this home energy efficient 

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 definitely 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.
