Compare bids by assumptions

Contractor Bid Compare

Enter two or three contractor totals, mark what each bid documents, and see which one is actually ready to compare before you choose by price.

Compare 2-3 contractor bids

A low total is only useful when the written scope, allowances, payment terms, and contractor basics are comparable.

What makes two bids comparable?

Two bids are market evidence only when they price the same written work, terms, access, and risk assumptions.

Same written scope

Comparable when: Each bid names the same rooms, surfaces, fixtures, demolition, prep, cleanup, exclusions, and assumptions.

Weak signal: One bid is a lump sum while another lists detailed inclusions, exclusions, or site assumptions.

Material and allowance parity

Comparable when: Allowances, product lines, quantities, finish level, owner-supplied items, and substitution rules are written down.

Weak signal: One contractor assumes builder-grade materials while another assumes premium fixtures, tile, cabinets, paint, or equipment.

Access, permit, and disposal responsibility

Comparable when: Permit decision, inspection responsibility, parking/loading, HOA or building access, protection, dumpster, and disposal are assigned.

Weak signal: Permit, access, cleanup, disposal, elevator booking, or property-manager requirements are handled verbally or left for later.

Timeline and start window

Comparable when: Start window, expected duration, crew days/hours, lead times, delay handling, and completion or punch-list expectations are written.

Weak signal: The bid says "soon," "about a week," or gives only a verbal schedule without lead-time or delay terms.

Warranty, cleanup, and closeout

Comparable when: Labor warranty, material warranty handling, exclusions, cleanup, punch list, inspection closeout, and callback process are included.

Weak signal: The contractor says they stand behind the work, but warranty duration, exclusions, cleanup, or callbacks are not written.

Payment and change-order terms

Comparable when: Deposit, progress payments, final payment trigger, accepted methods, and written change-order approval before extra work are clear.

Weak signal: Most money is due upfront, change orders are verbal, or extra work can be billed after the fact without written approval.

Which assumptions can change the final price?

Mark these for each bid only when the quote writes down who owns the cost, approval, or closeout responsibility.

Allowance amount and product level

Why it matters: Material allowances can turn a fair-looking bid into an expensive change order if amount, product level, and owner-supplied items are not written.

Ask for: Please show each material allowance amount, assumed product level, owner-supplied item, and who pays if the final selection costs more.

Prep, demo, and repair scope

Why it matters: Prep, demolition, patching, substrate repair, or protection work can be excluded while the total still looks complete.

Ask for: Please state what prep, demolition, patching, repair, protection, and site setup are included or excluded.

Permit, inspection, and disposal responsibility

Why it matters: Permit fees, inspections, hauling, dumpsters, and disposal can shift to the homeowner after the quote is accepted.

Ask for: Please state who handles permit decisions, permit fees, inspections, hauling, dumpster or disposal, and closeout documents.

Access, protection, and work-hour limits

Why it matters: Parking, elevator booking, HOA or building access, common-area protection, and work-hour limits can change labor time and schedule.

Ask for: Please show any access assumptions, parking or loading needs, elevator or HOA requirements, protection plan, and work-hour limits.

Hidden-condition and change-order trigger

Why it matters: Hidden damage, old wiring, plumbing surprises, rot, moisture, or framing issues can become open-ended extra work without a written trigger.

Ask for: Please define which hidden conditions could change price, how they will be documented, and what written approval is required before extra work starts.

Cleanup, punch list, and closeout

Why it matters: Cleanup, final walkthrough, punch-list timing, warranty documents, and final payment triggers are often left vague until the end.

Ask for: Please confirm cleanup, final walkthrough, punch-list timing, warranty documents, and what must be complete before final payment.

What counts as documented contractor proof?

Mark a contractor basic only when the proof is written and can be kept with the final quote.

License / registration

Counts as proof: A license or registration number, issuing authority, trade category, and business name that match the contractor or company bidding the work.

Weak signal: A verbal "we are licensed" answer, a number without the issuing authority, or a license that belongs to an unrelated business.

Insurance certificate

Counts as proof: A current certificate of insurance naming the insured business, coverage type, policy dates, and any building or property-manager requirements.

Weak signal: A badge on a website, an expired certificate, or a generic statement that insurance exists without coverage dates or business name.

Written scope

Counts as proof: A written quote or proposal that names the rooms, surfaces, fixtures, materials, allowances, prep/demo, cleanup, exclusions, and assumptions.

Weak signal: A single total with "labor and materials" only, or a text message that does not say what is included or excluded.

Payment schedule

Counts as proof: Deposit amount, payment milestones, final payment trigger, accepted methods, and what must be complete before each payment.

Weak signal: "Pay as we go," "most upfront," or a large deposit request without milestones, completion criteria, or refund/cancellation terms.

Change-order process

Counts as proof: A written rule that extra work requires homeowner approval before work starts, with pricing method, documentation, and who can approve it.

Weak signal: Verbal approval, after-the-fact billing, or "we will figure it out onsite" without unit rates or written approval steps.

Warranty terms

Counts as proof: Written labor warranty length, material warranty handling, exclusions, callback process, and whether warranty transfers if the home is sold.

Weak signal: "We stand behind our work" without duration, exclusions, response process, or distinction between labor and material warranty.

Permit responsibility

Counts as proof: A written permit decision, who pulls the permit, who pays fees, inspection responsibility, schedule impact, and final closeout documents.

Weak signal: "No permit needed" without project-specific reasoning, or assuming the homeowner handles permits without saying so in the bid.

Start date / duration

Counts as proof: Written start window, expected duration, crew days/hours, access needs, cleanup plan, delay terms, and punch-list or closeout expectations.

Weak signal: "We can start soon" or "about a week" without start window, daily access requirements, delay handling, or completion criteria.

    How to use the result

    • The best current candidate should have both a plausible total and enough written assumptions to compare.
    • A lower bid with missing exclusions, warranty, payment terms, or insurance is not automatically cheaper.
    • An above-range bid can still be valid when it clearly documents premium materials, access constraints, permits, or site conditions.
    • Ask every contractor to answer the same missing items before you compare final totals.
    This tool does not choose a contractor for you. It shows which bids are ready for a fair comparison and which ones still need written answers.
