Construction Calculator FAQ
Do construction calculators replace a contractor quote?+
No. They are planning estimates. Site conditions, waste, local product sizes, labor, and codes can change the final requirement.
Should I add a waste factor?+
Usually yes. Waste factors help cover cuts, spills, uneven surfaces, mistakes, and material variation.
