How to negotiate a contractor quote (without losing the good one)
The short answer
Contractor quotes typically come down 8–20% when you get 2–3 bids on identical written scope and negotiate line by line — labor rate and materials markup separately. Name the competing bid without bluffing, offer something real in return (flexible timing, fast decision, deposit), and put the change-order rate and warranty terms in the contract before signing.
Identical scope is everything
You cannot negotiate "a new roof" — you can only negotiate a written scope: tear-off vs overlay, shingle brand and line, underlayment spec, flashing detail, disposal, warranty. Write the scope once (or have the first contractor write it, then use their document) and get every bidder to price THAT. Three bids on the same scope routinely spread 15–30%, and the spread is your negotiation before you say a word.
Negotiate labor and materials separately
The blended quote hides the two margins. Ask for the split. Materials carry a contractor markup (often 10–35%) — on big-ticket items (windows, HVAC units, cabinets), offering to purchase materials yourself or at cost-plus is a real lever. Labor is negotiated on rate and on scope realism: "Your labor is 40% of this quote — the other bid has the same scope at 30%. Walk me through the difference." Sometimes there is a good reason (better crew, faster schedule, real warranty); sometimes there is just margin.
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.

Start freeQuestions 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?
- Typically 10–35% depending on the trade and the item. Big-ticket equipment (HVAC condensers, appliances, windows) carries the most visible markup. You will rarely get zero markup — sourcing and warranty coverage is worth something — but asking for cost-plus on the two or three biggest items routinely saves 5–10% of the job.
- 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.
