Siding estimate template — and a generator that fills it in
What's behind the old siding decides whether you made money. Here's the structure, plus a generator.
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 siding estimate should contain, plus a checklist of what siding 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 siding jobs are bid
Siding is bid per square of wall area, with trim, corners, and openings priced per linear foot or per unit because they are the detail work that sets the pace. What is behind the old siding — sheathing condition, house wrap, rot around windows — is unknown until removal starts and belongs in the estimate as an allowance rather than a guess. Tear-off and disposal are their own line.
What a siding estimate should contain
- Wall square footage by elevation, and the number of stories
- Siding product, profile and colour
- Tear-off of existing siding, by layer
- Sheathing replacement as an allowance with a per-sheet overage rate
- House wrap or weather-resistive barrier
- Trim: corners, J-channel, window and door surrounds
- Flashing at windows, doors and roof-wall intersections
- Soffit and fascia if included
- Scaffolding or lift on multi-storey elevations
- Dumpster and disposal
- Labor as crew days × rate
What gets left out of siding estimates
- Rotten sheathing found at tear-off — always an allowance, never a silence
- Window flashing details, which is where callbacks and leaks come from
- Scaffolding on two-storey walls, which is real cost and real setup time
- Colour and profile matching when you are only replacing one elevation
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.
