How to Read a Contractor Bid

Every clean contractor bid in 2026 includes eight sections: project scope, materials and equipment, labor by trade with hours, allowances, exclusions, payment schedule, change-order policy, and warranty. ContractShield bids enforce this structure inside the Work Order Marketplace, so three bids on the same project arrive in the same field order.

If a bid is missing a section, ask before signing. Bids that hide labor inside a single bundled total or skip exclusions are doing more than saving space. They are leaving room to walk back scope later.

Open the scope section and confirm every task in your work order is listed. Demo, rough-in, finish, paint, cleanup, and warranty service are all separate items. The order should match the build order. A bid that puts paint before drywall or finish before rough-in is poorly organized, and poor organization usually means a contractor who has not pre-planned the job.

Look for tasks that appear in one bid but not another. That is a scope gap, not a price difference. Ask the contractor without that line whether the task is included under a different heading or excluded entirely.

Brand, model, tier, and quantity. A bid that lists 'quartz countertops' without a brand or tier is using an allowance disguised as a spec. Spec lines should read like 'Cambria Brittanicca, slab 3cm, 38 square feet' not 'quartz countertops.' The same rule applies to fixtures, appliances, flooring, paint, and hardware.

If any material line is vague, ask for an upgrade and downgrade option in writing. ContractShield bids prompt contractors to spec material brand and tier on every line, and a missing brand flags the bid for clarification.

Labor should be listed by trade, with either total hours or total labor cost per trade. A bid that says 'labor: $14,200' is hiding hours. A bid that says 'plumber 32 hours, electrician 24 hours, tile setter 48 hours, carpenter 36 hours' tells you the scope, the schedule, and the cost simultaneously.

Labor hour estimates are also the place where bid variation reveals truth. If three bids show 60, 64, and 95 labor hours on a bathroom remodel, the 95-hour bid is either including scope the others missed or padding hours. Ask before signing.

An allowance is a placeholder dollar amount for a material or fixture that the homeowner has not selected yet. 'Vanity allowance: $1,200' means the bid covers a vanity up to $1,200, and any vanity above that costs extra.

Allowances are the single biggest source of bid confusion. Two bids with identical scope can show very different totals because their allowances are different. Normalize allowances across bids before comparing totals. ContractShield flags allowance mismatches in the side-by-side bid view.

When you can, replace allowances with specs. Once you have selected a vanity, replace 'vanity allowance: $1,200' with 'Wyndham Andover 30-inch vanity in espresso, model WCV810130SES.' The bid becomes a real bid.

Exclusions are what the contractor will not do for the bid price. Common exclusions: surprise repairs found during demo, code upgrades required by the inspector, hazardous material remediation (asbestos, lead paint, mold), permit fees if not listed, and any work caused by the homeowner's own actions or other trades.

A bid with no exclusions is often a bid that will surface those exclusions as change orders mid-project. Ask the contractor without exclusions to add the standard list to the bid. ContractShield bids include an exclusions section by default to make this conversation easier.

Progress payments should tie to milestones, not calendar dates. A clean payment schedule reads like '15% deposit at contract signing, 25% at demo complete, 25% at rough-in inspection pass, 25% at finish complete, 10% at punch list complete.' Calendar-based schedules let payment outrun progress.

Most states have laws capping initial deposits at 10 to 30% of the contract. Check your state law if a contractor asks for more than 30% up front. ContractShield contracts auto-generate milestone-based payment schedules tied to verifiable on-site events.

Three warranty lines matter: labor warranty length, material warranty pass-through, and what voids each. A standard residential labor warranty in 2026 runs 1 to 2 years. Material warranties pass through directly from the manufacturer and require registration within 30 to 90 days.

Void clauses to watch: improper homeowner maintenance, modifications by other contractors, and acts of nature. A warranty that lists 'normal wear and tear' as a void is too vague. Ask for specifics.

Variation across three bids is almost always a scope gap, not a price gap. Walk each line item across all three bids. The line with the most variation is usually the one to ask about. Sometimes you find one contractor included a permit fee that the others left as exclusions. Sometimes one contractor allocated 16 hours to a task that another allocated 4 hours to.

Once scope is normalized, the bid totals usually fall within 10 to 15% of each other. The lowest bid is rarely the right pick. The bid with the cleanest line items and the most realistic labor hour estimates is the right pick. ContractShield surfaces these normalized comparisons inline.
