1. Estimates only
Results are estimates for planning and ordering. Real jobs need extra for waste, cuts and breakage, and material yields differ by product. Always check the manufacturer's instructions and your supplier.
2. Codes and permits
Code figures on the site (for example stair rise and run) are common model-code values. Your local building department sets the rules that apply to you. Get permits where required and use a licensed professional for structural, electrical and gas work.
3. No liability
You use the site at your own risk. To the extent permitted by law, we are not liable for material shortfalls, overruns, failed inspections, injury or any other loss.
4. Copying
Print and share your own job sheets freely. Do not copy the calculators or guides to another site.
5. Fair use
No bulk scraping, spam or attempts to break the site.
6. Updates
Terms may change; the date above shows the version in force. Contact crew@builders-tools.com.
