Our goal is simple: pages that help you make a better decision, with numbers you can check.

How we write

  • Guides are written for US readers in plain English and focus on the next practical step.
  • We cite public sources, such as federal agencies, when we state a specific fact or recommendation, and link to them.
  • We don't invent statistics, prices, reviews, testimonials or experiences.

Numbers and calculators

  • Repair prices vary widely by location, season and home. We don't publish national price tables unless we can name and verify the source.
  • Calculators show their formulas and assumptions. Default prices are clearly labeled as examples, and you are asked to enter your own local prices.
  • Every result is labeled as a planning estimate, not a contractor quote.

Review and updates

Each page shows a “Last reviewed” date. We review pages when sources change or readers report a problem, and update that date only when a page was actually reviewed.

Advertising

Ads are kept separate from tools and download buttons and are labeled “Advertisement.” Advertisers have no influence on what we publish.

Corrections

If you find an error, please tell us. We fix confirmed errors promptly.
