What should be included in a contractor estimate?

Short answer

A usable estimate is written and itemized: the contractor's legal name, license number and contact details, a specific scope of work, materials by type and grade, labour, permits, disposal, exclusions, the total price, the payment schedule, the estimated schedule, and how long the price is valid.

Full explanation

An estimate is the document you use to compare bids and, later, to prove what was promised. A single number on a business card is not an estimate.

It should contain:
- Contractor identity — legal business name, physical address, phone, license number and insurance details.
- Scope of work — specific tasks in plain language, room by room or area by area.
- Materials — product, grade, quantity, colour or model where relevant, and who supplies them.
- Labour — crew and hours or a clearly stated fixed labour price.
- Permits and inspections — who applies, who pays.
- Site work — protection, demolition, debris removal and disposal, cleanup.
- Exclusions — everything explicitly not included. This section prevents most disputes.
- Allowances and contingencies — how unknowns such as hidden rot or code upgrades will be priced.
- Total price, and whether it is a fixed price, cost-plus or time and materials.
- Payment schedule tied to milestones.
- Schedule — expected start and substantial completion.
- Validity period and the date of the estimate.
- Warranty summary for labour and materials.

Estimate versus quote versus bid: a quote or fixed-price bid is a firm price for defined work; an estimate can be an informed projection that may move. Ask which one you are receiving, and get it in writing.

State-specific rules

In Florida, confirm the estimate names the exact licensed entity — certified or registered — that will hold the permit, and that permit responsibility is stated. Florida permitting runs through your local building department, and permit fees can be a meaningful line item on larger jobs.

Common mistake to avoid

The exclusions section is the one most homeowners skip and the one that causes most disputes. If disposal, painting, patching or permits are not named, assume they are not included and ask.
