How to Read a Contractor's Bid Before You Sign: Questions, Red Flags, Line Items

A written bid is the one document that tells you how a job is actually going to go — not the sales pitch, not the handshake, not the "we'll take care of you" line. If you can learn to read one properly, you can usually tell which contractors are organized and which ones are guessing before you ever hand over a deposit. This is a companion piece to our full guide on hiring a general contractor in Louisville, which covers cost ranges, verification steps, and permit timelines. This post is narrower: the questions to ask, the red flags to watch for, and how to actually read the bid in front of you.

Start with what the bid is missing, not what it includes

Most bad bids aren't dishonest — they're incomplete. The contractor quoted what they were thinking about and left out what they weren't. Before you compare price, scan for these gaps:

• No start or completion date, even a rough one
• No payment schedule, just a total due
• No mention of permits, on a job that clearly needs one
• "Labor and materials" as a single line, with no breakdown
• No exclusions listed — what's NOT included matters as much as what is

A bid with gaps isn't automatically a bad contractor. It might just mean you need to ask for a revision before you sign. A bid that still has gaps after you ask is a red flag.

Questions to ask before you compare numbers

Ask these on the phone or at the walkthrough, before bids come back, so every contractor is pricing the same scope:

• "What's included in this number, and what's not?"
• "How do you handle conditions you can't see until you start — rock, bad soil, unmarked utilities?"
• "What's your payment schedule, and what triggers each payment?"
• "Who pulls the permit, and is that fee in your number or separate?"
• "What's your estimated start date, and how firm is it?"
• "Can you give me two references from jobs in the last 12 months, in my area?"

If a contractor answers all six without hesitation, they've done this before. If they get vague on the payment schedule or the unforeseen-conditions question, that's where problems usually start.

How to read the payment schedule

A standard, fair payment schedule in Kentucky residential work runs close to 30% deposit, 30% at a mid-project milestone, and 40% on completion. Variations exist for good reasons — a job with expensive custom materials might need a bigger deposit to order them — but the shape should make sense for the work.

What doesn't make sense:

• More than half the contract price due before work starts. At that point you've financed most of the job with no leverage left if something goes wrong.
• A single lump payment due on a vague "completion." Completion should be tied to a specific, inspectable milestone — not a feeling.
• No final payment held back. A small holdback until punch-list items are done gives you real leverage to get a clean finish.

Reading the scope section line by line

The scope is where vague bids hide the most risk. Compare it against what you actually asked for:

• Does it name the materials (brand, grade, thickness) or just say "standard materials"?
• Does it specify quantities — square footage, linear footage, depth — or just a general description?
• Does it note site conditions assumed (access, existing grade, utility locations)?
• Does it separate the main scope from allowances — items priced as a placeholder because the final selection isn't made yet?

A scope that says "excavate and grade backyard" tells you nothing. A scope that says "excavate to 8-inch subgrade across approximately 1,800 sq ft, compact in two lifts, 4 inches of #2 stone base" tells you exactly what you're paying for and gives you something to hold the finished work against.

Red flags that should stop you before you sign

• Verbal-only quotes. If it's not in writing, it's not a commitment — it's a conversation.
• Pressure to sign the same day, especially with a "this price is only good today" line.
• Cash-only requests. No paper trail means no recourse if something goes wrong, and it's often a sign of unreported income or no insurance.
• No proof of license or insurance offered without being asked. A legitimate contractor hands this over before you have to request it.
• Door-to-door solicitation after a storm. Storm-chasing crews collect deposits and move to the next county before problems surface.
• No physical address or local phone number. A real local contractor has a Kentucky number and a truck you could find twice.
• A bid dramatically lower than the others with no explanation. Somebody is missing scope, cutting corners, or planning to make it up in change orders.

What a complete bid actually looks like

Put together, a bid worth signing includes:

• A detailed scope with quantities and materials specified
• A total price broken into major line items, not a single lump sum
• A payment schedule tied to milestones, not arbitrary dates
• A stated start date and realistic duration
• Who's responsible for permits, and whether that cost is included
• What happens if unforeseen conditions show up (rock, bad soil, hidden damage)
• Exclusions — what's explicitly not part of this price
• Proof of license and insurance, offered or easily provided

Comparing two bids the right way

Line up the scopes side by side before you look at the bottom-line numbers. If one bid is itemized and the other is a lump sum, ask the lump-sum contractor to break it down the same way — any legitimate contractor can do this in a day. Once both are itemized the same way, the real differences in price usually trace back to real differences in scope: one assumed haul-off and the other didn't, one included permit fees and the other left them separate, one priced a rock contingency and the other didn't mention rock at all.

That's the whole point of reading a bid carefully — not to catch someone trying to cheat you, but to make sure you're actually comparing the same job twice.

Verify before you sign, not after

A bid can look perfect on paper and still come from a contractor who isn't who they say they are. Confirm the Kentucky license is active, ask for a certificate of insurance naming general liability and workers' comp coverage, and call the two references instead of just reading the Google reviews. Our guide to hiring a general contractor in Louisville walks through the full verification checklist and typical timelines by project type if you want the longer version.

If you're getting ready to request bids on an excavation, site prep, or outdoor living project in Louisville or the surrounding counties, reach out for a written, itemized estimate — Eric and Jerry quote every job themselves, so the person who priced it is the person who shows up.

Why "lowest bid wins" is the wrong strategy

The instinct to take the cheapest number is understandable — nobody wants to overpay. But on a construction bid, price is a function of scope, and scope is a function of what's written down. A contractor who skipped the permit line, assumed no rock contingency, and used a lighter base-stone spec will always come in lower than one who priced the job correctly. The cheap bid doesn't disappear — it comes back as a change order once the work has already started and you have far less leverage to say no.

A useful rule: throw out the lowest bid and the highest bid, and look hardest at the middle ones. The lowest often means missing scope. The highest sometimes means padding, but more often means a contractor who's priced in every contingency because they've been burned before. The middle bids are usually the ones who scoped it accurately.

What to do if a bid comes back vague

Don't walk away immediately — ask for a revision. Send back the specific questions from this post: materials, quantities, payment schedule, permit responsibility, and how unforeseen conditions get handled. A contractor who tightens up the bid without complaint is showing you how they'll handle the job itself. A contractor who gets defensive about being asked to clarify their own bid is telling you something too.

Put it in writing, even the small stuff

Any change to the original scope — a different paver color, an added square footage, a schedule shift — should show up as a written change order with a price attached before the work happens, not as a verbal "yeah, we can do that" on-site. Verbal add-ons are the single most common source of billing disputes on residential jobs, and they're entirely avoidable with a one-line signed change order.

The short version

Read the scope before you read the price. Ask the six questions above before bids even come back. Watch for the red flags — verbal-only quotes, same-day pressure, cash-only, no license or insurance offered. Compare itemized line items, not just totals. And get every change in writing, no matter how small. A contractor who's comfortable putting all of this on paper is a contractor who's done the job enough times to know what belongs in a bid.
