What this worksheet is and why it helps

The Insulation Cost Worksheet is a simple PDF you can download and use at home. It is free and no signup is required.

The goal is not to give you a firm quote. It is to help you build a reasonable estimate range for your project. That way, when you start comparing prices, you have a better idea of what affects the total.

Insulation pricing can change a lot from one home to another. The real price usually depends on the area being insulated, the R-value target, the material you choose, the age of the home, how easy the space is to access, whether old insulation needs to be removed, and your region. If you want a broader overview of typical ranges, visit insulation costs.

The worksheet is especially helpful if you want to compare more than one option, such as attic vs. crawlspace work, or blown-in insulation vs. batt insulation.

How to use it

You do not need special software or technical knowledge. Just download the PDF, fill in your project details, and use it as a planning tool.

  1. Write down which area you want to insulate, such as the attic, walls, crawlspace, basement, or rim joists.
  2. Estimate the size of the area in square feet.
  3. Add your R-value target. In plain language, R-value means how well insulation slows heat flow. Higher R-value means more resistance to heat moving in or out, but more is not always better after you reach the recommended level for your climate.
  4. Compare material types you are considering, such as blown-in cellulose, fiberglass batts, or spray foam.
  5. Note extra work that may affect price, like air sealing, cleanup, or removing old insulation.
  6. Use your worksheet when reviewing written estimates from licensed and insured installers.

Before you hire anyone, verify the installer's license and insurance yourself, and get the scope of work, price, and the R-value the job will reach in writing before any deposit. You can also review how to vet an insulation installer.
