Crawl Space Cost Calculator


Crawl spaces are an essential part of many homes, providing access to utilities and serving as an important foundation element. When considering crawl space projects, it’s crucial to estimate the associated costs accurately. Our Crawl Space Cost Calculator simplifies this process by providing a quick and reliable estimate.


To calculate the cost of a crawl space project, use the following formula:

Total Cost = Length (in feet) × Width (in feet) × Height (in feet) × Cost per Square Foot

How to Use

Using our Crawl Space Cost Calculator is straightforward:

  1. Enter the length of the crawl space in feet in the “Length” field.
  2. Input the width of the crawl space in feet in the “Width” field.
  3. Specify the height of the crawl space in feet in the “Height” field.
  4. Enter the cost per square foot for the project in the “Cost per Square Foot” field.
  5. Click the “Calculate” button.

The calculator will provide you with an estimated cost for your crawl space project.


For example, let’s say you have a crawl space with dimensions of 20 feet in length, 10 feet in width, and 3 feet in height. The cost per square foot for your project is $20. Using our calculator:

Total Cost = 20 ft × 10 ft × 3 ft × $20/sq. ft = $12,000

So, the estimated cost for your crawl space project would be $12,000.
