Terms of Service
BuildWise Calculators provides estimates and educational information only. The results from any calculator on this site are estimates based on the inputs you provide and standard industry formulas or published cost ranges. They are not a substitute for professional measurement, engineering review, or licensed contractor estimates.
Do not rely on any calculator output as the sole basis for ordering materials, signing a contract, or making structural decisions. Always verify quantities with your supplier and obtain itemized quotes from licensed contractors for any significant renovation work. Building codes and permit requirements vary by jurisdiction; consult your local building department before starting any project that may require permits.
The site is provided “as is.” Cognitic Labs LLC makes no warranties as to the accuracy, completeness, or fitness for any particular purpose of the calculators or content. Use of this site constitutes acceptance of these terms.
