Contact
The form below is how to contact DIY Totals. Use it for either of two reasons: you spotted a figure that looks wrong, or you want a calculator or material the site does not have yet. A submitted message goes to the site operator by email.
The clearest corrections name the page, the figure you expected, and the figure you saw. That combination lets the operator find the right entry and fix it. Suggestions are just as useful when they name a material or a project type. After you send the form, the site operator receives an email with your message, and an automatic confirmation goes to the address you gave. Replies typically arrive within a few days.
DIY Totals calculators show both imperial and metric units for every material.
How do I report a wrong figure or bad result?
Use the form on this page. Include the page you were on and the figure you expected alongside the figure you saw. That lets the operator find and correct the entry.
How do I suggest a new calculator or material?
Use the form and name the material or project type you want. Project types are as useful as material names, so include both if you can.
Is there a phone number or postal address?
No phone number and no postal address are published. The form on this page is the only contact route.
