About
We publish national cost ranges so homeowners can read a contractor quote before they sign it.

What this site is for
Most people hire a contractor a handful of times in their life. The contractor does it every day. That gap is why a quote can feel unarguable even when it is high, and closing it is the only thing this site does.
Every cost page gives a national range, the average within it, and the reasoning underneath — what drives the number up, what a complete quote should itemize, and when the range does not apply.
Who writes this
Written and edited by the Cost Home Book editorial team
Cost Home Book is written and edited by the Cost Home Book editorial team. The team builds the site's cost models from publicly available US wage statistics, supplier price lists and permit data, and updates each guide as those sources change. It has no affiliation with any contractor, manufacturer or lead-generation service. Figures on this site are estimates for reading a quote, not quotes.
More about the team, how the figures are built, and every guide on the site.
How we are funded
Display advertising, and nothing else. We take no referral fee, no commission and no lead payment from any contractor, manufacturer or marketplace, and we do not sell the pages we price.
No contractor can pay to change a number, to be named in a cost guide, or to have a competitor removed. An advertiser sees a figure when you do. If any of that ever changes, it will be written here before it happens.
What we are not
We are not a contractor, an estimator, or a licensing body. The figures here are national estimates for orientation before you get quoted. They are not a quote, and they cannot account for your house, your access, or your local market.
