Frequently Asked Questions

What should a contractor estimate include?

A professional estimate should include an itemized list of materials with quantities and unit costs, labor hours broken down by task, project timeline, payment terms, and your company’s license and insurance info. Including these details builds trust and reduces back-and-forth questions from clients.

How do I calculate material costs for an estimate?

Start by creating a detailed takeoff of every material needed for the job, then price each item at current retail rates from suppliers like Home Depot or your wholesale distributor. Add 10–15% for waste and breakage, and update prices regularly since material costs fluctuate throughout the year.

Should I show labor and materials separately?

Yes, separating labor and materials gives your client transparency and builds confidence in your pricing. It also protects you during negotiations—clients can see exactly where costs come from and are less likely to ask for blanket discounts when every line item is justified.

How long should an estimate be valid?

Most contractor estimates are valid for 30 days, though some contractors use 15 or 60 days depending on material price volatility. Always state the expiration date clearly on the estimate so clients understand that pricing may change if they delay approval beyond that window.
