Editorial policy

Last updated September 2026

Independence

Advertisers, contractors and manufacturers have no say in our price ranges or recommendations. We don't accept payment to include, exclude or rank anything.

Accuracy

Figures are reviewed on a regular schedule and when readers report changes. Each page shows when it was last updated.

Corrections

If you find an error, email hello@housemathguide.com with the page address. We review every report and update the page when a correction is needed.

Advertising

HouseMath is supported by display advertising served by Google and its partners. Ads are clearly separated from editorial content, and we don't write content to promote advertisers.

Scope

We cover costs and practical decisions about home projects. We don't give financial, legal, insurance, tax or safety-engineering advice. For those, consult a qualified professional.
