How we get these numbers

Published, not estimated.

Every amount goes through three independent checks before it is allowed on the site, and we throw out far more than we keep. We also separate the price of a window from the price of a job: mixing the two produces a range that describes nothing.

Companies that never answer us stay listed with whatever they publish publicly, and giving us prices does not move anyone up a page.
