Contact
Questions, corrections and suggestions are all welcome.
Good reasons to get in touch
- A figure looks wrong. Tell me which calculator, the numbers you entered and what you expected. A screenshot helps.
- A calculator you'd like. Fencing, decking, retaining walls: suggestions decide what gets built next.
- Retailers and partners. If you sell materials or services covered here, I'm happy to talk.
What I can't help with
I can't give advice on a specific site or survey your job. For anything structural, near a building's foundations, or on very soft ground, ask a local builder or engineer. The calculators are estimates for ordering materials.
