Frequently asked questions

Should a contractor estimate include a contingency?+

Yes — 5-15% depending on project complexity. List it as its own line. This signals to the customer that you're planning realistically, and protects you when surprises happen.

How do I handle change orders?+

Note in the estimate: "Any changes to scope will be billed separately and require written approval before work proceeds." This sets clear expectations from day one.

Estimate or quote — which one should a contractor use?+

For projects with hidden variables (structural, ground conditions), use an estimate. For fixed-scope work like a deck or a single-room job, a quote is more confident and easier to compare.
