Frequently asked questions
Why add a contingency buffer on top of materials, labor, and permits? Renovation projects routinely uncover unexpected issues (like hidden water damage) once work begins, so a 15% contingency buffer is a standard planning margin against cost overruns, not an optional extra.
Is the contingency calculated on the total budget or just materials and labor? The contingency percentage is applied to the sum of materials, labor, and permits/fees, giving a buffer proportional to the full estimated project cost.
