Deck building estimate template — and a generator that fills it in
The line items a deck estimate needs — deck area, railing length, footings and the inspection sequence — plus a generator that drafts one from your description of the build.
Generate this estimate now
Describe the job in plain words. No email needed to see your first estimate — about fifteen seconds for a small job, a little longer for a big one.
What you get — see the format first
A complete estimate you can send to the customer, built from the rate you enter:
| Description | Qty | Unit | Unit price | Total |
|---|---|---|---|---|
| Labor — itemized by task | hrs | hour | your rate | — |
| Materials — with your markup applied | qty | ea / sq ft | cost + markup | — |
| Permits, disposal, access | — | — | — | — |
Plus a plain-English scope summary, assumptions (what had to be guessed), exclusions (what you are not doing — the section that prevents most change-order arguments), and a validity period. Printable, or send the link.
Every figure comes from the rate and markup you supply. We never fill in a market price for you.
An estimating spreadsheet that opens in Excel, Numbers or Google Sheets, or prints to PDF. Pre-filled with the line items a deck building estimate should contain, plus a checklist of what deck building estimating most often leaves out — so you price it before you send, not after.
- Blank — the line items, ready to price by hand.
- Auto-calculating — same sheet with the maths built in; type a quantity and a rate and it totals itself. Formulas work in Excel and Google Sheets.
- Printable — a clean one-page layout to fill in on site or save as PDF.
How deck building jobs are bid
Decks are bid per square foot of deck surface plus per linear foot of railing, and the two scale differently — a small deck with a lot of perimeter is expensive per square foot. Footings are set by code and soil, not by the customer's budget, and the inspection sequence means the frame has to be seen before the boards go on. Material choice drives both cost and labour: composite fastens differently from wood and hides its own fasteners, which takes longer.
What a deck building estimate should contain
- Deck square footage and the height above grade
- Footings: number, diameter, depth to frost line, and concrete volume
- Framing — beams, joists, hangers, ledger and its flashing
- Ledger attachment detail and the fasteners the code requires
- Decking material, board width and the fastening system
- Railing by linear foot, with baluster type and infill
- Stairs: number of risers, stringers, treads and the landing
- Permit and the framing inspection before deck boards go down
- Demolition and disposal of an existing deck, if any
- Labour as carpenter hours by phase — footings, frame, deck, rail
What gets left out of deck building estimates
- Ledger flashing, which is the single most common source of rot and failure
- Frost depth footings priced at the local requirement, not a guess
- Grade and soil at the footing locations, and hand-digging near the house
- Site protection and the route for getting material into a fenced back yard
Your prices, not internet averages
Generic AI quotes national averages. BidWand builds a price book from every estimate you send and every rate you correct, so by the fifth bid it prices like you do — your labor rate, your markup, your exclusions.
