Terms of Use

Educational purpose

MendNook provides general DIY informational content, not professional repair, safety or engineering advice. Dimensions and material recommendations can vary across manufacturers and products; verify your particular system before purchase or repair.

Your responsibility

Use appropriate protective equipment and care with cutting tools and glass. Stop and seek an experienced installer when damage, sharp components or unusual structural systems create a risk.

Content rights

Text and original site graphics may not be copied and republished in substantial part without permission. External source material remains owned by its respective publishers. Links to external references do not imply a partnership.

Calculators and measurement decisions

Tools on MendNook organize the dimensions you enter and produce educational estimates or decision paths. They do not inspect your home, detect a hidden defect, establish a safe installation method, or automatically create a manufacturer's order specification. Review units, measurement points, model details and fit tolerances before ordering or cutting anything.

Sources and corrections

We link to external manufacturers and other sources for context; their recommendations may be updated or may not apply to your exact hardware. MendNook does not control external websites. See our Editorial Policy for how we use sources and handle corrections. You can report a broken link, unclear instruction or calculation concern through our Contact page.

No guarantee

The information is provided as a general reference, without a guarantee of compatibility with every product or installation situation. Verify specifications with the appropriate manufacturer. If a task involves unsafe access, glazing, structural damage, fire-rated doors or child-safety hardware, seek appropriate qualified advice rather than relying on a generic article.
