Three contractors walk your kitchen remodel and come back with bids of $42,000, $58,000, and $71,000. The instinct is to call the $42,000 contractor and start scheduling. That instinct causes more change orders, more disputes, and more unfinished jobs than almost any other decision homeowners make during a renovation. A bid is not a price tag. It’s a proposal built on assumptions, and those assumptions vary wildly between contractors.
Make sure the bids describe the same project
Before comparing dollar figures, compare scope. Pull up each bid and check what materials are specified. One contractor’s $58,000 bid might include quartz countertops at $65 per square foot installed, while another’s $42,000 bid lists “countertops, allowance $2,800” without naming a material. That’s not a cheaper bid. That’s an incomplete one, and the gap gets filled later with a change order.
Look for these specifics in every bid:
- Exact product names or model numbers for fixtures, appliances, and finishes
- Square footage or linear footage for flooring, tile, and countertops
- Brand and grade of lumber, drywall, or insulation where it matters structurally
- Whether permits, dumpster rental, and site cleanup are included or billed separately
If one bid is missing this detail, call the contractor and ask for it in writing before you compare anything else. A bid without specifics isn’t a lower price. It’s a placeholder.
Break every bid into the same four categories
Contractors format bids differently, which makes side-by-side comparison harder than it should be. Fix this by rebuilding each bid into four buckets: materials, labor, permits and fees, and contractor markup/profit. Most contractors will share this breakdown if asked directly, even if their original proposal lumped everything into a single number.
Here’s why this matters with real numbers. Say two bids for a bathroom remodel both come in around $28,000. Bid A allocates $9,000 to materials, $14,000 to labor, $1,000 to permits, and $4,000 to markup. Bid B allocates $14,000 to materials, $8,000 to labor, $500 to permits, and $5,500 to markup. Bid B is planning for higher-grade materials but budgeting less time for installation. That’s a red flag for tile work, cabinetry, or anything requiring precision, since low labor hours often mean a rushed schedule or a smaller crew than the job needs.
Read the exclusions list as carefully as the inclusions
Every legitimate bid should have a section listing what is not covered. This is often where the real price difference hides. A $45,000 bid that excludes electrical panel upgrades, structural repairs if rot is found, and disposal of old materials can turn into a $53,000 project once work starts. A $52,000 bid that already accounts for a worst-case electrical scenario might finish at exactly $52,000.
Ask each contractor these questions directly and get the answers in writing:
- What happens to the price if you find water damage or rot behind the walls?
- Is the permit fee an estimate or a fixed number, and who pays if it’s higher?
- Does the bid include disposal and dump fees, or will that show up as a separate invoice?
- Are subcontractor costs (electrical, plumbing, HVAC) already locked in, or are they placeholder estimates?
A contractor who answers these clearly and specifically is telling you they’ve actually thought through the job. A contractor who gets vague or annoyed is telling you something else.
Weigh the contractor’s track record against the number on the page
Price comparison only works if you also compare who’s doing the work. Ask each contractor for three references from jobs completed in the last 12 months, and actually call them. Ask the reference two specific questions: did the final cost match the bid within 10%, and did the project finish within two weeks of the promised date. These two data points predict future problems better than almost anything else you can ask.
Check how each contractor is licensed and insured for your specific state and project type. A general contractor without an active license bond, or one carrying only $300,000 in liability insurance for a project involving structural work, is a financial risk regardless of how good their bid looks. Request certificates of insurance directly from the insurance company, not just a photocopy from the contractor, since bids sometimes list coverage that lapsed months ago.
Payment schedules also reveal a lot. A contractor asking for 50% upfront on a $60,000 job is asking you to front $30,000 before a single wall comes down. Standard practice in most states caps deposits at 10% to 30% depending on local law, with the rest tied to completed milestones (framing done, rough-in inspected, drywall hung). A bid with an aggressive upfront payment structure paired with the lowest price should raise more questions, not fewer.
Run the numbers through a simple cost-per-outcome test
Once scope, categories, and exclusions are aligned, compare bids on cost per unit of actual outcome instead of total price. For a deck project, that might mean cost per square foot including footings, railings, and stain. For a full kitchen, it might mean cost per linear foot of cabinetry plus a separate line for countertops and appliances. This strips out bundling tricks where one contractor inflates labor to offset a materials discount, or vice versa.
A $61,000 kitchen bid at $580 per linear foot of cabinetry with soft-close hardware and plywood boxes is a different product than a $54,000 bid at $510 per linear foot with particleboard boxes and standard hinges. Once you see the unit cost and the material grade side by side, the “expensive” bid often turns out to be the better value, and sometimes it doesn’t. The point is you’re now comparing like with like instead of guessing.
Take the three or four bids you’ve collected, rebuild each one using the categories above, and put them in a single spreadsheet with columns for materials, labor, permits, exclusions, and payment terms. Once the numbers are aligned this way, call your top two choices back with specific follow-up questions before signing anything.
