Contractor quote checklist: 10 things to verify before you sign

Run every contractor quote, bid or estimate through these ten points before you sign. Each one is a recurring source of change orders, disputes or disappointment — and each one can be settled up front with a single question to the contractor.

1. 1 Verify who the contractor actually is

   The full business name, address and license number (where your state or country requires one) belong on the quote. Look the contractor up with your state licensing board or local registry, and ask for proof of general liability insurance — and workers’ compensation if they bring a crew. A name on the truck that doesn’t match the name on the quote is a question to settle before you read any further.

2. 2 Read the scope of work like an outsider

   Does the quote say concretely what will be done, where and how? If you couldn’t explain the job to a neighbor from the description alone, it’s too vague. The bigger the number at the bottom, the more that vagueness matters.

3. 3 Hunt for what is NOT included

   The most expensive line items are often the missing ones: demolition, haul-away and disposal, dumpster fees, permits, code upgrades, site protection, and patching or repainting after the work. Ask for an explicit exclusions list — a professional contractor has one ready.

4. 4 Demand brand- and model-level specifications

   “Builder-grade”, “quality paint” or “energy-efficient windows” mean nothing until brand, model or rating is on paper. Without specifications the materials can be downgraded during the job without you noticing — and you can’t compare bids fairly.

5. 5 Count the allowances

   An allowance is a placeholder amount for something not yet chosen — tile, fixtures, appliances. Ask for each one: why is this still open, is the amount realistic for what I actually want, and how is the difference settled? Several large allowances mean the “total” on the quote is not really a total.

6. 6 Judge the deposit and payment schedule

   Payments should follow the progress of the work, with a meaningful final payment due after completion — that is your leverage to get punch-list items finished. A large deposit up front shifts the risk to you; some states cap deposits for home improvement work, so check your local rules before agreeing.

7. 7 Get the change-order rule in writing

   Change orders are where thin bids win back their margin. Have it written down: no extra work without your written approval of a description and price first, at labor rates and markups that are named in the contract today — not invented mid-project.

8. 8 Check the warranty for substance, not the word

   A real warranty names a duration, says what it covers — workmanship, materials or both — and lists the exclusions. “Manufacturer’s warranty applies” covers the product, not the installation. If the workmanship warranty is missing or hedged, have it made concrete before you sign.

9. 9 Read the liability terms and ask about lien releases

   Fine print often caps the contractor’s liability at the invoice amount, or excludes consequential damage. Ask for the full terms and conditions if they aren’t attached. In the US, also ask how lien releases are handled: if a contractor doesn’t pay their subcontractors or suppliers, a mechanic’s lien can land on your property — a release process protects you.

10. 10 Check the tax treatment and distrust price pressure

    Is sales tax (or VAT, depending on your country) included, excluded or partly applied? The quoted number should be the number you’ll actually pay. And be wary of a very short validity period with an announced price increase: pressure to sign quickly is rarely in your interest.

Frequently asked questions

What is the difference between a quote, a bid and an estimate?

Usage varies, but broadly: an estimate is an educated guess that may change, while a quote or bid is a concrete offer for a defined scope at a stated price. The label matters less than the content — check whether the document commits to a scope, a price and conditions. If it calls itself an estimate, ask what would make the price final.

How large a deposit is normal for contractor work?

There is no universal number, and some states cap deposits for home improvement contracts. The principle matters more than the percentage: payments should track the progress of the work, materials-heavy jobs may justify more up front, and a meaningful final payment should be due only after completion.

What is an allowance in a contractor quote?

A placeholder amount for an item not yet selected, such as tile or fixtures. You pay the actual cost later, so the allowance level determines whether the quote total is realistic. Ask what each allowance is based on and how differences are settled — an allowance set low makes a bid look cheaper than it will be.

Do I have to accept the lowest bid?

No — and the lowest bid is often low because something is missing: exclusions, thin allowances, or no change-order terms. Compare bids on the same scope and the same conditions before comparing the price. A bid you can’t line up item-for-item against another isn’t comparable yet.
