What is most useful to send
- A figure that looks wrong, with the page address and, if you have it, the source that says otherwise.
- A material, project size or topic you would like covered.
- A supplier, manufacturer or extension guide whose data we should check.
What we cannot do
We cannot give a quote, design your project, or tell you whether a particular job is safe or legal where you live. For anything structural, electrical, or involving permits, ask a qualified professional and your local building department.
We do not answer questions about orders placed on Amazon or with any retailer. Contact the seller for that.
