Frequently Asked Questions

How long should a construction quote be valid for?

14–30 days. Materials prices (steel, timber, copper) can move 5–10% in a month. State the validity clearly so the client knows to commit.

Do I need a separate contract, or is the signed quote enough?

For jobs under ~$10k a signed quote with clear scope, payment terms, and exclusions usually suffices. For larger jobs, attach standard terms (or use a JCT/AIA/local construction contract) — the quote becomes the schedule of works inside that contract.

How much deposit should I ask for?

20–30% on jobs under $20k; up to 50% on jobs where you have to order long-lead materials upfront. Be ready to itemize the deposit against materials so the client can see where it goes.
