How to Read a Contractor Bid — Before You Sign Anything

The top of any professional bid should identify: contractor name and company, license number, insurance certificate reference, your name and property address, and the date the bid was prepared and when it expires.

• ✓ Good sign: License number listed. You can verify it with your state licensing board.
• ⚠ Red flag: No license number, no expiration date, or a bid that's been sitting undated for months and may no longer reflect current material prices.

This is the most important section. It defines what the contractor is and is not going to do. Read every sentence. Ambiguity here is expensive later.

• ✓ Good sign: Explicit "included" and "excluded" lists. You want to see "not included: appliance removal" stated directly rather than leaving it to interpretation.
• ⚠ Red flag: Vague language like "kitchen renovation per homeowner specifications" — this is not a scope definition, it's a blank check waiting for a dispute.
• ⚠ Red flag: No list of exclusions. Everything not explicitly excluded is implicitly included — in your mind. In the contractor's mind, it may not be.

What specific materials is the contractor using? "Tile" is not a specification. "Daltile Restore 12x24 in Matte Arctic" is a specification. The difference can be $4,000 in a bathroom renovation.

• ✓ Good sign: Brand, model, grade, and dimensions specified for major materials. "Or equivalent" is acceptable if the specification is clear.
• ⚠ Red flag: Material "allowances" (e.g., "$800 tile allowance"). An allowance means if you pick tile that costs $1,100, you're paying the $300 overage — at contractor markup. Always ask what specific product an allowance is based on.

Labor costs should be broken out by trade or phase — demolition, rough work, finish carpentry, tile installation, painting. A single "labor" line item gives you no ability to evaluate whether the price is reasonable or to identify which trade is doing what.

• ✓ Good sign: Labor broken out by category. You can cross-check against industry averages for your area.
• ⚠ Red flag: Single undifferentiated "labor and materials" lump sum. This is the hardest kind of bid to compare and the easiest to pad with change orders later.

Most structural, electrical, and plumbing work requires permits. The question is: are permit costs included in this bid, and who is responsible for pulling and managing permits?

• ✓ Good sign: "Permit costs included" or "homeowner responsible for permits" — either is fine, as long as it's explicit.
• ⚠ Red flag: No mention of permits on a project that clearly requires them. The cost gets added later as a change order, or the work proceeds without permits (your liability).

How and when you pay matters as much as how much you pay. The payment schedule is a leverage tool — your ability to enforce quality and completion depends on maintaining financial control throughout the project.

• ✓ Good sign: Payments tied to milestones (e.g., "30% at rough-in inspection, 30% at drywall completion, 30% at final walkthrough, 10% at punch list completion"). You pay for work done, not work promised.
• ⚠ Red flag: More than 30% upfront. A contractor asking for 50%+ before work starts has no financial incentive to finish quickly. If they claim they need it for materials, offer to pay materials suppliers directly.
• ⚠ Red flag: Calendar-based payments rather than milestone-based. "First payment due 2 weeks after start" incentivizes starting, not completing.

When does the work start? When does it finish? Are there milestone dates for key phases? A bid with no timeline is a bid with no accountability.

• ✓ Good sign: Specific start date, projected completion date, and key milestone dates. Penalty provisions for schedule overruns signal a contractor who takes timelines seriously.
• ⚠ Red flag: "We'll start when we can" or no completion date at all. Renovation projects without deadline accountability routinely drag months past projected completion.

Changes happen on almost every project. The question is whether changes are handled through a structured process or ad hoc verbal agreements. Get the change order process and markup rates in writing before you sign.

• ✓ Good sign: "All changes require a written change order signed by both parties before work proceeds. Change orders priced at cost + 15%."
• ⚠ Red flag: No change order clause. Disputes about scope changes are one of the most common sources of contractor conflicts — without a documented process, you have no recourse.

What does the contractor stand behind after the job is complete? Labor warranties, material warranties, and manufacturer warranties are all different things.

• ✓ Good sign: Explicit labor warranty period (typically 1 year minimum), plus pass-through of manufacturer warranties on materials and fixtures.
• ⚠ Red flag: No warranty language at all. This is a contractor who doesn't expect to be called back.
