Affiliate Disclosure

SprayFoamCalc is free to use. Some links on this site are affiliate links: if you click one and then buy a product or request a service, the company may pay us a commission. It costs you nothing extra.

Where you will see them

• The results page, next to the professional-installation and DIY estimates (for example a link to request local quotes, or to a DIY spray foam kit).
• Some guides and articles, where a product or service is mentioned.

Affiliate links are marked as sponsored in the page code, and a note appears near them on the results page.

What it does not change

• The calculator's formulas and price ranges are the same whether or not an affiliate link is shown. We do not raise or lower an estimate to favour a partner.
• Our methodology is public so you can check the numbers yourself.

As an Amazon Associate we would earn from qualifying purchases, should we add Amazon links in future. Questions about this disclosure: kundingwhale@gmail.com.
