Blueprint Calc is run by a small independent team. We read every message.
Found a bug or a math error?
We want to know. If a calculator produces a number that looks wrong, or an FAQ contains outdated information, email us the specific page and what you were expecting. We prioritize these fixes over everything else.
Are you a manufacturer or retailer?
We partner with a small set of retailers through Impact Radius, Amazon Associates, and direct deals. If you represent a home improvement brand with a product that would genuinely help the DIYers who visit this site, we are open to hearing from you — but we do not accept paid placement that misleads our users.
Contractor / lead-gen partners
For lead-generation partnerships (deck, concrete, roofing, windows, solar) we work with Angi, HomeAdvisor, Modernize, and direct contractor networks. Reach out with your program details and payout terms.
We aim to reply within two business days. High-volume partnership inquiries may take longer.
