Crawl Space Insulation Contractors

Insulating Crawl Spaces in the Washington, DC Metro Area (including Virginia & Maryland Suburbs)


crawl space insulationCrawl spaces aren't given a lot of thought when we think about the most important features in our home. But without proper crawl space insulation, you can end up with comfort problems throughout your home, and lots of wasted energy – and money. Crawl spaces that have dirt floors or moisture problems end up being cold in the winter and damp in the summer.

Do You Have Crawl Space Insulation Problems?

There are a few telltale signs that your crawl space is poorly insulated:

  • The crawl space often feels damp.
  • You can see and/or smell mold.
  • Any existing insulation has shifted or fallen out of place.
  • There are rodents or insects in the crawl space.
  • The floor above crawl space is very cold in the winter, and you have to keep the heat constantly running to keep the room above the crawl space comfortable in cold weather.

The Wrong Crawl Space Insulation

Crawl spaces used to be insulated by installing fiberglass batting between the joists in the space. However, fiberglass is not an optimal solution, because it can get soggy with moisture, compress and lose its insulating value. While fiberglass insulation is a cost-effective option, any money saved by using it is lost when the material no longer works.

Use Rigid Foam Panels for Crawl Space Insulation

Rigid foam panels are made at differing thicknesses, and are cut to perfectly fit crawl space walls. They are then secured with mechanical fasteners or adhesives to make sure they always stay in place.

Crawl Space Encapsulation

Crawl space encapsulation means sealing off your crawl space from the exterior of your house, and rigid foam panels are often used to do this. Though rigid foam costs more to install than fiberglass insulation, it can be less expensive in the long run because it can perform better and won't have to be replaced. It's a one-time solution to an energy-wasting problem.

Benefits Of Rigid Foam For Crawl Space Insulation

1) It's Reliable

Rigid foam won't compress like fiberglass insulation. It stays where it is installed, and retains its R-value over time.

2) Acts as an Air Sealant

When they are taped together, rigid foam panels can stop air leaks, saving energy and money.

3) Stays Dry

Because rigid foam panels don't contain any organic material, they don't absorb moisture, so mold and compression are not a problem.

Learn More About Insulation

We were unaware of what was involved in an energy audit and your audior took the time to explain everything. We were impressed with the report which told us the areas in which we need to take action on. He never pressured us to use any particular contractors, he just suggested that we go to the HomeEnergyTeam web site to select contractors of our own choice. He did an excellent job and we HIGHLY recommend the Home Energy Team Affiliates. We already have recommended them to several of our neighbors. Again, EXCELLENT JOB!

Willie Gantt

Your home energy audit proved to be very informative and helpful. I was not aware of the updraft created inside our walls because of the balloon framing construction. You said that that can cause heat to be pulled out of the house with the draft going up inside the walls and should be re-mediated. You also said that the attic insulation was insufficient and that fiberglass batts can leave spaces for around the edges causing heat loss and that it should have blown in insulation on top of what was there to seal the whole attic and increase the R factor. Thank You for all your advice and expertise. You made me aware of things I should consider and did the upgrades. I can already see the difference on my utility bills!
