Corrections
If a cost figure is wrong for your market, send the project scope, your location and what you actually paid or were quoted. Specific numbers get acted on; general complaints that prices "seem high" are harder to use.
Contractors
We do not sell placement inside calculators and we do not adjust estimates on request. If you want to supply regional pricing data for a trade you work in, we are interested — that improves the figures for everyone.
