Crawl Space Encapsulation Cost Calculator

Crawl Space Encapsulation is a vital step in maintaining a healthy and energy-efficient home. It involves sealing and insulating the crawl space beneath your house to prevent moisture, pests, and heat loss. One of the critical considerations when planning crawl space encapsulation is the cost. To make this process more accessible, we’ve created the Crawl Space Encapsulation Cost Calculator.


The formula used in this calculator is quite simple. We calculate the total cost based on the following formula:

Total Cost = Area (sq. ft) × Cost per Sq. Ft. ($)

How to Use

Using the Crawl Space Encapsulation Cost Calculator is straightforward:

  1. Enter the length, width, and height of your crawl space in feet.
  2. Input the cost per square foot for encapsulation materials and labor.
  3. Click the “Calculate” button.
  4. The calculator will display the estimated cost for encapsulating your crawl space.


Let’s say you have a crawl space with a length of 30 feet, a width of 20 feet, and a height of 2 feet. The cost per square foot is $5. Using the calculator, the estimated cost would be:

Estimated Cost = 30 ft × 20 ft × 2 ft × $5/sq. ft = $600
