How to Estimate Wall Construction Costs - Framing Through Finish
Wall construction costs stack up in layers - framing lumber, sheathing, insulation, drywall, and finish - and each layer has its own material and labor calculation. The framing drives everything: stud spacing (16" or 24" OC), header sizes over openings, and whether the wall is load-bearing change both the material list and the labor hours. A contractor who estimates wall construction by applying a single cost-per-linear-foot rule without accounting for these variables will be right on average and wrong on every individual job.
This guide walks through the layer-by-layer cost buildup for interior wall framing through finish, explains the load-bearing vs. partition distinction that changes the estimate, and covers the stud count math that drives material quantities.
