How to Quote a Job: A Complete Estimating Guide

The six-step quote process

1. Walk the job. Don't quote sight-unseen unless it is a $100 service call you have done 50 times. The site visit is where you spot the gotchas that wreck your margin.
2. Write the scope. List exactly what is included AND exactly what is excluded. Excluded items prevent change-order arguments.
3. Price each line item. Materials, labor, subs, permits, equipment rental, disposal — every cost gets its own line, with a unit price.
4. Add contingency. 10% for routine work, 15% for renovation, 20%+ for anything behind a wall or underground. This is not padding — it is the buffer that keeps you whole when reality intrudes.
5. Attach terms. Payment schedule (deposit, progress, final), validity window (typically 30 days), late-fee policy, and your warranty.
6. Present and follow up. Hand-deliver or schedule a call to walk through the quote. Follow up by text or email at 48 hours, then again at one week.

What a winning quote looks like

A winning quote does three things at once: itemizes enough to justify the price, totals to a single confident number at the bottom, and signals professionalism through clean formatting and clear terms. Customers who get three quotes are looking for reasons to disqualify. Don't hand them ammunition.

Include: scope, exclusions, line-item pricing, totals, deposit amount, validity date, your license number, insurance certificate reference, warranty, and a signature block. Send as a PDF — never as a text in the body of an email.

Contingency math

On a $5,000 bathroom remodel, 15% contingency adds $750 to the price. If everything goes smoothly, that $750 is profit. If the subfloor is rotted under the tub (it usually is), the $750 covers the surprise without you having to call the customer for a change order.

Customers do not see your contingency line — it is rolled into your labor or 'site preparation' line item. Internally, you track it as a margin buffer.

The follow-up sequence that wins more jobs

75% of jobs are won by the contractor who follows up first. Send a text within 48 hours: 'Hi Sarah — checking if you had any questions about the quote I sent. Happy to walk through it on a call.' If no answer in a week, follow up again with a soft scarcity nudge: 'I have an opening the week of the 22nd — wanted to give you first option before I book it out.'

Stop chasing after three touches. A customer who has not responded in three weeks is not coming back.
