Our goal is simple: give homeowners cost information they can trust before they talk to a contractor. This page explains how we choose topics, research numbers, and keep our guides up to date.

How we choose topics

We write about the repairs and replacements homeowners actually search for and ask about: what a job costs, how long a system lasts, the warning signs that something is failing, whether it is worth repairing, and what insurance usually covers. Reader questions and correction requests also shape what we write next.

How we research costs

• Public and official sources, such as the U.S. Department of Energy, ENERGY STAR, the Environmental Protection Agency, and the Consumer Product Safety Commission.
• Industry organizations, such as the International Association of Certified Home Inspectors (InterNACHI) for typical component lifespans, and trade associations for roofing, chimneys, and water damage.
• Manufacturer pricing and specifications for equipment such as water heaters, HVAC systems, and generators.
• Published contractor rates and reader-reported quotes, which help us check that our ranges match what people really pay.

We present costs as ranges rather than single numbers, explain what moves the price up or down, and link to our sources where possible.

How articles are written and reviewed

We use AI writing tools to help with research summaries and first drafts. Every article is then reviewed and edited by a human editor before it is published. During review we check prices and facts against our sources, remove anything we cannot support, add practical context, and make sure the article answers the reader’s question clearly.

Keeping guides up to date

Prices change with materials, labor, and regulations. Each guide shows the date it was last reviewed. We revisit our most-read guides at least once a year and update any guide sooner when a reader or a source tells us something has changed.

Corrections

If we get something wrong, we fix it. Send corrections through our Contact page. When a correction changes a key number or recommendation, we update the review date on the article.
