Crawl Space Insulation

If your crawl space is uninsulated or poorly insulated, it can cause significant discomfort throughout your whole house due to air infiltration and heat and energy loss.

During your FREE insulation evaluation and thermal imaging test, our technicians will recommend the best insulation products to keep your crawl space dry, energy efficient and structurally sound. We’ll also ensure that your crawl space is thoroughly sealed.

The US Department of Energy recommends that crawl spaces are sealed and insulated. At MGT Insulation, we can help you choose affordable insulation options that will keep your crawl space functioning at top efficiency.

When applying spray foam insulation in a conditioned crawl space that is accessible to the home, fire retardant must also be installed per building code.

Step 1: Diagnostic Testing

Our highly trained technicians use state-of-the-art equipment to identify areas of energy savings for you. An infrared camera, especially done in conjunction with a blower door test, can identify uninsulated and poorly insulated crawl spaces.

Note: We also recommend the investment in an independent energy audit from your utility company. The cost is fairly low and heavily subsidized — meaning that its actual cost would be much higher without the contribution by the utility.

Step 2: Prep Work Area

We carefully protect your home, business, and belongings with thorough worksite preparation, including clean drop cloths, plastic, window jamb protectors, corner guards, and our state-of-the-art Air Scrubber filtration system.

Step 3: Lay Vapor Barrier

A 6-millimeter plastic vapor barrier is placed on the ground to reduce underground moisture from entering your crawlspace.

Step 4: PPE

Our team wears appropriate protection to ensure safety.

Step 5: Apply Insulation

We insulate by spraying our high quality closed-cell spray foam insulation or installing THERMAX™ brand insulation to the walls and rims of your crawlspace.

Step 6: Apply Fire Retardant

We spray an additional fire retardant on the walls and rims of your crawlspace to ensure safety. In conditioned crawl spaces that are accessible to the house, we insulate with spray foam.

Step 7: Post Blower Door Test

We perform another blower door test to increase comfort due to reduced air leakage throughout your crawl space.

Step 8: Health and Safety Check

Our crews perform a “Worst Case Scenario” test to ensure that your structure is safe from carbon monoxide and your family, pets, employees, or customers are protected.

Step 9: Clean Work Area

Our crews know how to broom clean and vacuum!

Step 10: Post Inspection

To ensure that our job is complete, we walk with you through your home or business to inspect the work. During this time, we’ll answer any questions, get your stamp of approval, and have you complete our job satisfaction survey.
