Editorial Policy
Sources
Every cost figure on this site carries a source line naming where it came from and when it was published. We use published cost guides, manufacturer documentation, building-code and consumer-protection guidance, and homeowner reports. We do not invent prices and we do not accept prices from contractors in exchange for coverage.
Dates
Each guide shows the date it was last updated. Costs move; a figure older than a year should be treated as a starting point, not a quote.
Author
Guides are written by Maren Holloway, home improvement researcher. Maren Holloway is not a contractor, does not sell window replacement, and does not hold a trade licence. See About Maren Holloway for how the guides are researched.
Corrections
If a figure or fact is wrong, tell us at hello@daytonwindowcosts.com. We correct the page and note the change.
What this site is not
It is not professional advice, not a quote, and not a contractor. Decisions about your home should be made with a licensed professional who has seen it.
