About
About BuildMate
BuildMate started with a simple observation: every home project starts with a calculation, and every calculation starts with a Google search. We're building the one platform where the math, the materials, the guides and the AI planning live under one beautiful roof.

Built for accuracy
Every calculator shows its formula, its assumptions and its waste allowance on the page, so you can check the math instead of trusting a black box. Cost tools use published national price ranges with a state adjustment factor.
Documented methods
Guides and cost articles are written and checked in-house using documented calculation methods and published reference information. We do not claim third-party professional review.
Honest and independent
BuildMate is free for homeowners because we believe transparent pricing is the foundation of a better renovation industry.
Privacy first
We don't sell your data. Saved calculations stay in your browser, and you can export or delete them anytime.

Frequently asked questions
- Is BuildMate really free?
- Yes. Every calculator, guide and the AI estimator are free. We may add optional premium features in the future, but the core tools will stay free.
- Where do the cost numbers come from?
- We build low-to-high ranges from publicly published national material and labor pricing, then apply a state cost factor. They're planning ranges, not live local pricing or binding quotes — see our methodology page for the full breakdown.
- Can I save or share my estimate?
- Yes. Each calculator lets you save results to your browser, download a PDF, email them, or share a link.
- How do I request a new calculator?
- Use the contact form or email support@buildmat.app. We build the most-requested tools every month.
