Affiliate Disclosure

Crawlspace Lab is reader-supported. When you click certain links on this site and make a purchase, we may earn an affiliate commission from the retailer, at no additional cost to you. This is how we fund the research and verification work behind this site.

What this does not change

Commission structure never determines which products we cover, how we score them, or whether we recommend against a product. Our product database and verdicts are built before we know which programs will approve us, and they don't change if a program does or doesn't.

Retailers we may link to

Depending on program approval status, this may include Sylvane, The Home Depot, and Amazon Associates, as well as select manufacturer direct-affiliate programs. Retailer links are markedrel="nofollow sponsored" per search-engine guidelines for paid or affiliate links.

This complies with the FTC's guidance on clear and conspicuous disclosure of material connections. If you have questions about a specific link, contact us.
