The ventilated crawl space beneath your home is often out of sight and out of mind. But this key area can be the source of musty smells, mold, pests, and animal life that make their way into your living spaces. Plus, your uninsulated crawl space could be costing you money! At Standard Insulating Company, our crawl space encapsulation services can improve your home comfort in a number of ways, and provide some other benefits you might not have thought of.

What’s in Your Crawl Space?

Crawl spaces here in the greater Charlotte area — including those in Gastonia, Mooresville, Concord, and Rock Hill — were originally designed for free air flow to help keep homes cool in the summer. Crawl spaces of this design have vents installed and often feature a dirt, concrete, or gravel floor. Unfortunately, this configuration allows pollen, mold, moisture, animal waste, and other unpleasant substances to accumulate in the crawl space area. Over time, this damp, dirty environment can create problems for your family.

Changes in air pressure and leaks throughout a home bring the air from the crawl space into the ground level and upper floors, causing mold, mildew, and moisture to accumulate in your living space. This greatly reduces indoor air quality and will exacerbate asthma, allergy, and other respiratory symptoms. 

Plus, if your crawl space is under-insulated, you could be wasting valuable energy used to heat and cool your home! The dirty air from underneath your home is often a different temperature than the rest of the home, negating the work of your heating and cooling system. 

Crawl Space Encapsulation Benefits

Upgrading your crawl space with encapsulation can improve your home energy efficiency, comfort, and indoor air quality in several ways:

  • Humidity and moisture control
  • Pest protection
  • Improved comfort year-round
  • Energy savings
  • Reduced allergens and mold
  • Cleaner, safer indoor air quality
  • No more cold floors in the morning

Our Encapsulation Services

The professional technicians from Standard Insulating Company will first inspect your crawl space as part of a free energy analysis. Based on that inspection, we’ll be able to recommend ways to improve your home, including the crawl space, attic insulation, wall insulation, and air sealing. If encapsulation is one solution you opt for, here’s our crawl space encapsulation process:

Clean Out Crawl Space

Our team will take out old insulation, debris, and other materials from the crawl space and safely remove them from your property.

Seal & Insulate

Once any debris is cleared out, the crawlspace team will first air seal any gaps or cracks with expanding spray foam. Then we apply insulation to the foundation wall, between the floor joists, and around grates and ductwork. As with all our insulation upgrades, we use Owens Corning fiberglass insulation for the highest quality and performance.

Dehumidifier Installation

To remove moisture and prevent mold and mildew, the technicians will install a dehumidifier inside the crawl space.

Install Clean, White Crawl Space Vapor Barrier

Installing heavy-duty white sealing film is the final step of the crawl space water proofing and encapsulation process. This 12 to 15 mil thick plastic is applied to all surfaces and tape sealed to create a single continuous barrier for crawl space moisture control, to deter pests, and to ensure your insulation stays intact.

Once your crawl space encapsulation is complete, you’ll major a big difference in air quality, comfort, and energy savings!
