Free Construction Estimate Template (and What Every Line Should Contain)

An estimate is a promise with a price on it. The template below is the structure we see on the estimates that get approved without a “can you explain this?” call. Download it as an Excel workbook or CSV (open either in Google Sheets with File › Import), or copy the structure into the tool you already use.

The eight sections of a construction estimate

1. Header: your business name, license number, phone, email and the estimate number and date.
2. Customer and site: name, phone, email, and the job address (not the billing address if they differ).
3. Scope of work: three to eight plain-English sentences describing what you will do and what “done” looks like.
4. Line items: description, quantity, unit, unit price, line total — grouped by phase or trade.
5. Allowances: items the customer has not chosen yet (tile, fixtures) with the budget you have assumed.
6. Exclusions: what is not included — permits, haul-away, painting, anything a customer might assume.
7. Totals and payment schedule: subtotal, tax if applicable, total, deposit, draws and final.
8. Validity and approval: how long the price holds, and a signature or approval line with a date.

The template

Header and customer block

Estimate #, date, your license number and insurance statement (“Licensed and insured, policy available on request”). Customer name and the job address. If you work in a state that requires a specific disclosure on home-improvement contracts, it goes here, not buried at the end.

Scope of work

Write it the way you would say it on the driveway: “Remove existing 100 A panel and install a new 200 A Square D panel with a 40-space interior. Rewire existing circuits to new breakers. Install new meter base and mast. Coordinate utility disconnect and reconnect. Patch drywall around the panel; painting by owner.” That last clause is the whole reason the scope exists — it tells the customer where your work ends.

Line items

One line per thing a customer could ask about. Group by phase (Demo · Rough-in · Finish) or by trade on a multi-trade job. Quantities with units (sq ft, LF, EA, HR). If you price labor separately from material, keep them on separate lines; if you price by assembly (“Install 20 A circuit, EA”), say so in the scope so nobody asks why there is no wire line.

Allowances and exclusions

Allowances are the budget you have assumed for choices the customer has not made (“Tile allowance: $6/sq ft material”). State that the final price moves with the selection. Exclusions are the list that prevents the most arguments: permit fees, dumpster, painting, landscaping repair, anything behind a wall you cannot see yet. If you had to explain it on a past job, it belongs in exclusions.

Totals, payment schedule, validity

Subtotal, tax where it applies, total. Then the schedule: deposit at signing, draw at a named milestone, balance on completion. Finally a validity line (“Prices valid for 30 days”) and the approval line. A dated approval is what turns the estimate into an agreement.

Mistakes that make customers call back

• A single lump sum with no lines — customers assume the number is negotiable because they cannot see what it buys.
• No exclusions section — every unlisted thing is assumed included.
• Allowances with no number — “tile allowance” with nothing after it is a future dispute.
• No validity date — material prices move; your estimate should expire.
• Separate estimate and invoice formats — when the final invoice does not look like the estimate, every line gets re-examined.

Three tiers beat one price

If the job allows it, present Budget, Standard and Premium as three complete scopes, each with its own line items and total. The customer compares options instead of negotiating a single number, and the middle tier is usually the one that closes. In a spreadsheet that is three copies of the line-item block; in software it is one toggle.

One legal note for the signature line: if the customer signs at their home, the FTC’s Cooling-Off Rule (16 CFR Part 429) gives them until midnight of the third business day to cancel, and requires you to tell them so in writing — add that notice to the estimate you ask them to approve.
