How to Read a Contractor's Estimate: Allowances, Exclusions and the 9 Lines That Cost You Later

Quick answer

A contractor's estimate is safe to sign only if it is a fixed price, itemized line by line, with every allowance stated in dollars, every exclusion written down, a change-order rule that needs your signature, and a payment schedule that leaves a real final payment for the walkthrough.

A contractor's estimate is safe to sign only if it is a fixed price, itemized line by line, with every allowance stated in dollars, every exclusion written down, a change-order rule that needs your signature, and a payment schedule that leaves a real final payment for the walkthrough. If the paper says 'estimate' with a total and no lines, it is not a price. It is a guess you will pay for later.

Here is how to read one in five minutes, and the nine lines that most often turn into a bigger bill.

First: is it a price or an estimate?

An 'estimate' is a prediction. A 'fixed price' or 'contract price' is a promise. In New Jersey, a registered home improvement contractor's contract for work over $500 has to be in writing with the total price, and any change to it has to be in writing too. Read the top of the page. If it says estimate, ask for the fixed price. If they will not give one, they are asking you to carry the risk of every surprise.

The 9 lines that cost you later

1. Allowances

'Tile allowance: $4/sq ft.' That means the price includes $4 tile. The tile you liked in the showroom is $11. You pay the difference, plus sometimes a markup on it. Ask for allowances that match what you actually picked, or pick before you sign.

2. 'Per plans' or 'as discussed'

There are no plans, or the discussion was in your kitchen with no notes. Every scope item should be a sentence you could hand to a stranger.

3. Exclusions

Look for the list of what is not included. Common ones: permits, debris removal, drywall repair after plumbing, painting, appliance hookup, moving the electrical panel, anything found behind the walls. If there is no exclusions list, ask for one; 'nothing excluded' in writing is the answer you want.

4. Permits

Who pulls them, and is the fee in the price? If the homeowner is asked to pull the permit, walk away. It shifts the liability to you and usually means the contractor is not registered.

5. 'TBD' and 'to be determined on site'

Common for structural work, electrical service, and rot. A fair version states a not-to-exceed number or a unit price ('rotted subfloor: $9 per sq ft'). An open TBD is a blank check.

6. Change orders

The clause should say: no change in scope or price without a written change order signed by you, with the price stated before the work is done. If it says changes are billed at 'time and materials', ask for the rates and a cap.

7. Payment schedule

New Jersey does not let a home improvement contractor collect more than a small portion up front, and you should hold at least 10% to 25% for the final walkthrough. A schedule that is 50% up front, 40% at demolition, 10% at the end means the money is gone before the tile is on the wall.

8. Materials and brands

'Faucet' is not a spec. 'Moen Align single-handle, chrome, model 6190' is. Same for windows, doors, roofing shingles and cabinets. If the brand is not written, the cheapest one arrives.

9. Timeline and finish date

A start date, a finish date, and what happens if they miss it. 'Approximately 4 to 6 weeks' with no start date is not a schedule.

What a good estimate looks like

  • The contractor's legal name, address, phone and New Jersey home improvement contractor registration number printed on it, along with insurance information.
  • One line per trade or task, each with its own number: demolition, plumbing rough, electrical rough, tile, fixtures, paint, cleanup, permit.
  • Allowances in dollars, next to the item, with the brand or product you picked.
  • An exclusions section, even if it is short.
  • A change-order rule that requires your signature.
  • A payment schedule tied to milestones you can see, with a real final payment.
  • A start date, a finish date, and a warranty statement.
  • A note that the price is good for a stated period (ours is 90 days).

Red flags that end the conversation

  • A total with no lines.
  • A price that is good 'today only'.
  • A big deposit before any work, or 'materials deposit' for a job that uses stock materials.
  • Cash discounts. It usually means no permit and no insurance.
  • You pulling the permit.
  • No registration number. Look it up on the New Jersey Division of Consumer Affairs site before you sign anything.
  • A contract that says the contractor can substitute materials of 'equal or greater value' with no approval from you.

Comparing three quotes that are $20,000 apart

Put them side by side and line them up by task. The cheap one is usually missing lines: no permit, no disposal, no drywall repair, a $2 tile allowance. Add those in at the other quotes' prices and the gap closes. Then look at the allowances against what you actually chose. Then look at who does the work: their own crew or subcontractors. Compare the scope, not the total.

How ours reads

One page per trade, every line priced, allowances set to the products you picked with us, an exclusions list that is usually empty, permits included, change orders only with your signature, no deposit on most jobs, and a final payment you hold until we walk the job together. The price is good for 90 days and we match any written quote scope for scope. If you cannot understand a line, we rewrite it.

Questions people ask next

What is an allowance on a contractor estimate?

A placeholder dollar amount for something you have not picked yet, like tile or a faucet. If your choice costs more, you pay the difference. Set allowances to what you actually chose before signing.

What is the difference between an estimate and a quote?

An estimate is a prediction that can change. A quote or fixed price is a promise that changes only with a signed change order. Always ask for the fixed price.

How much deposit can a contractor ask for in New Jersey?

New Jersey limits what a registered home improvement contractor can collect before work starts, and any contract over $500 must be in writing. A big up-front deposit is a warning sign either way. Read our guide on NJ contractor rules and the deposit law for the specifics.

What should a change order include?

A description of the change, the new price or credit, any change to the finish date, and both signatures before the work is done. Verbal changes are how surprise bills happen.

Should the cheapest quote worry me?

Usually. Line the quotes up by task; the cheap one is normally missing permits, disposal, patching or realistic allowances. Once you add those back, it often is not cheap.
