# [How to negotiate a contractor quote \(without losing the good one\)](https://trymumm.com/guides/negotiate-contractor-quote) > Give contractors the same written scope and compare their prices, materials, timing and warranties. Ask which changes to schedule or scope would improve the offer. Put the agreed work, payment milestones and change-order process in writing. - **Updated:** 2026-07-20 - **Category:** Contractors - **Read time:** 8 min ## Identical scope is everything Give each bidder the same written scope, including materials, removal, installation details and warranty. Ask them to identify exclusions and alternatives separately so you can compare like for like. ## Negotiate labor and materials separately Request a breakdown of materials, labor and overhead. Ask the contractor to explain differences from a comparable bid and price alternatives such as owner-supplied materials or a flexible schedule. Confirm how each option affects warranty and responsibility. ## What you have that they want - Timing flexibility: "I can take your slow week" is worth real money to a contractor filling a gap in the schedule. - A fast, firm decision: "I sign this week at $X" beats vague shopping — contractors discount certainty. - A reasonable deposit schedule: solid deposit now, milestone payments, never full payment up front. - Repeat-work potential: bathrooms after the kitchen, the rental property next year — mention it once, sincerely. - Referrals and reviews: a named promise ("I will write the review and refer my neighbors") costs you nothing and has real value to local shops. ## Lock the paper before the first hammer The negotiation is not done at the number — it is done at the contract. Lock: the change-order rate (the per-hour price for anything outside scope, where projects bleed), the payment schedule tied to milestones, the warranty in writing (workmanship years, separate from manufacturer warranties), start and completion windows, and who pulls permits. A contractor who negotiated in good faith puts all of it in writing without flinching. One who resists paper just told you something. ## Questions people actually ask ## Should I tell each contractor what the others bid? Share the existence of competing bids, and the number when it is real — never invent one. "I have $18,400 from a licensed roofer on the same scope. You are at $21,900. Can you close the gap?" Fabricated numbers get called ("who quoted that?") and poison the relationship. Real numbers move real discounts. ## Is the lowest bid ever the right choice? Sometimes — but check why it is low before falling in love. Missing scope (no disposal, cheaper shingle line, no permit) is the usual answer, and it surfaces later as change orders. Licensed, insured, references you actually call, same written scope — then the low bid is a win, not a trap. ## How much do contractors mark up materials? Ask how the contractor prices materials and what sourcing, delivery and warranty work the markup covers. Compare a fixed materials price with an agreed cost-plus arrangement and documentation. ## When is it rude to negotiate with a contractor? Never, done respectfully — trades expect it on any job over a few thousand dollars. The line is inventing competing bids, grinding after agreement, or treating a one-person shop's emergency rate like retail. Negotiate the scope and the margin, pay fairly and on time, and the good ones will pick your call first next time. ## Related - [How to negotiate a medical bill \(the actual playbook\)](https://trymumm.com/guides/how-to-negotiate-a-medical-bill) - [Out-the-door price: compare the complete car deal](https://trymumm.com/guides/out-the-door-price-car)
