Insulation estimate template — and a generator that fills it in
The line items an insulation estimate needs — square footage, R-value, air sealing and ventilation — plus a generator that drafts one from your description of the space.
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 insulation estimate should contain, plus a checklist of what insulation 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 insulation jobs are bid
Insulation is bid per square foot at a stated R-value, and the R-value is the whole contract — the same square footage at R-30 and R-49 are different jobs. Blown, batt and spray foam price differently per square foot and behave differently in the same cavity. The work that actually determines performance is air sealing before anything is installed, and it is the line most often dropped to win a price. Attic access, depth and heat set the labour, not the area.
What a insulation estimate should contain
- Square footage by area — attic flat, slopes, knee walls, rim joist, crawlspace
- Target R-value per area, stated explicitly
- Material and method — blown cellulose, blown fibreglass, batt, open or closed-cell foam
- Air sealing before installation: top plates, penetrations, chases, attic hatch
- Baffles at the eaves to keep the soffit vents clear
- Attic ventilation — intake and exhaust, and whether it meets the ratio
- Removal and bagging of existing material where required
- Vapour retarder or ignition barrier where code calls for one
- Attic hatch insulation and weatherstripping
- Labour as installer hours, with the access difficulty priced in
What gets left out of insulation estimates
- Air sealing quoted as included but not itemised — then not done
- Knee walls and cantilevers, which are usually the worst part of the envelope
- Can lights, bath fans and flues needing clearance or an airtight cover
- Ventilation checked before adding depth, or the new insulation blocks the soffits
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.
