Reading a Bid: 7 Line Items Every Homeowner Should Question

The number at the bottom of a contractor's bid is the smallest part of what matters. The line items above it tell you whether the bid is honest, complete, and likely to hold. Here are seven items every homeowner should know how to read — and question.

1. Allowances vs. specifications

An allowance is a placeholder dollar amount for materials whose specifics have not been finalized. Tile allowance: $4,000. Cabinet allowance: $18,000. Lighting allowance: $2,500. The contractor is committing to do the labor, but the actual selections you make later will adjust the price up or down from the allowance.

The trap: low allowances make a bid look cheap on paper. If your kitchen cabinets have a $12,000 allowance and the cabinets you actually want are $24,000, your final bill jumps $12,000 before you swing a hammer. The right question is, "What does this allowance actually buy me at the showroom you recommend?" If they have not visited a showroom yet, the allowance is a guess.

2. The site preparation line

This usually appears as "site prep" or "demo and protection" or sometimes is folded silently into general conditions. It covers protecting floors and walls in non-work areas, covering furniture, dust barriers, dumpster rental, debris removal, and any selective demolition required to start the actual scope.

A bid that does not have site prep as its own line, or has it suspiciously low (under $2,000 for a substantial remodel), is one of two things: a contractor planning to charge it as a change order later, or a contractor planning to skip it. Neither is what you want.

3. General conditions and overhead

This line covers the contractor's project management cost — the foreman's time, the dumpster, the porta-potty if needed, project insurance, vehicle and fuel costs to and from the site, and the office time spent scheduling subs. It usually runs 10 to 15 percent of direct construction cost on smaller jobs and 7 to 10 percent on larger ones.

If general conditions are missing or absurdly low (under 5 percent), the contractor is hiding the cost in the trade line items, which makes those trades look more expensive than competitors. If general conditions are above 18 percent, you are paying for inefficiency.

4. The MEP allowances (mechanical, electrical, plumbing)

This is where bids diverge most. Two contractors can be within 2 percent of each other on framing, drywall, and finishes, then differ by $30,000 on a kitchen remodel because one of them assumed the existing electrical panel was sufficient and the other assumed a panel upgrade.

Ask each bidder: "What did you assume about the existing electrical capacity, plumbing supply, and HVAC?" If they did not look in the panel or under the sink, the bid is a guess. The cheapest bid that did not assess these systems is almost always the one that produces the largest change orders.

5. Schedule and milestones

A bid with no schedule attached is incomplete. Even a one-page schedule with rough start, mid, and finish dates is enough to evaluate whether the contractor has thought about sequencing. For larger projects, you want a Gantt-style breakdown by trade.

The number that matters is not the start date — it is the substantial completion date. Schedules slip. The question is by how much, and whether the contractor has experience hitting the dates they put in writing. Ask for a recent reference whose project finished within 30 days of the original contract date.

6. Payment schedule

Look at how the bid wants to be paid. A reasonable payment schedule for a residential remodel is something like 10 percent down, then progress payments tied to completed milestones (rough framing complete, drywall complete, etc.), with a 5 to 10 percent retention held until punch list is closed.

Red flags: front-loaded schedules where 50 percent or more is due before substantial work starts; schedules tied to time rather than completion ("payment 2 due 14 days after start"); no retention held; a final payment due on substantial completion rather than after punch list. Each of these shifts risk to you in ways you do not want.

7. Exclusions and assumptions

Most bids list what is included. The honest bids also list what is excluded. Common exclusions include permit fees (sometimes covered, sometimes pass-through), engineering fees, soils tests, hazardous material remediation (asbestos, lead paint), structural surprises (rotted sill plate, undersized headers), and finished design selections beyond a baseline.

If the bid has no exclusions section at all, that is not a sign of generosity. It usually means the contractor will surface those issues as change orders later, and you will not have a frame for what was originally included. Ask explicitly: "What is excluded? What are you assuming about what we will find when we open up the walls?"

How to compare three bids honestly

Side-by-side comparison only works if all three bids cover the same scope. They almost never do out of the gate. Before comparing prices, normalize: take the most complete bid and ask the other two to either match the inclusions or list explicitly what they excluded. Ask each contractor to send their assumptions in writing. Then compare.

The lowest number is the wrong number to chase. The right number is the most complete bid from a contractor whose references actually answer the phone, whose license is verifiable in good standing, and whose schedule and payment terms are reasonable. That is the bid worth signing. The other two were just useful for comparison.
