Factual corrections: If a calculator constant, density value, or article claim appears wrong, include the URL, the specific claim, and a primary source reference (manufacturer spec, extension publication, or code citation) if you have one.
Source suggestions: Know of a better or more current source for one of our constants? We welcome primary source references that improve accuracy.
Calculator requests: We are adding estimators over time. If there is a common landscaping or construction material calculation that is hard to find elsewhere, let us know.
General feedback: If a calculator is confusing, returning a clearly wrong result, or breaking on your device, describe the issue and we will look into it.

Project-specific engineering advice (wall design, footing specifications for loads, structural framing). Please consult a licensed contractor or structural engineer in your jurisdiction.
Supplier pricing or availability — we do not have relationships with material suppliers.
Building permit guidance — contact your local building department for permit requirements.

We aim to respond to correction requests within 5 business days. Other inquiries may take longer depending on volume.
