About

HomeCostLab publishes cost ranges for common home improvement projects.

How the numbers are built

Each guide combines published national cost data with typical contractor pricing schedules, then gives a low-to-high range rather than a single figure. A single figure would be more satisfying and less true.

We do not accept payment for placement inside cost ranges, and we are not a contractor, lead-generation service or marketplace. We do not sell your contact details, because we do not collect them.

What the numbers do not cover

Regional labor rates, permit costs, structural conditions, lead paint, asbestos, frost depth and access all move a real quote well outside a national range. Use these pages to sanity-check a bid, not to replace one.
