Insulation contract template — R-value, air sealing and ventilation
An insulation contract is a promise about a number the customer cannot see. R-value, air sealing and ventilation all need stating, especially where a rebate depends on them.
This is a checklist of what a insulation contract has to settle — not a ready-to-sign legal document, and not legal advice. Most states regulate home improvement contracts: required disclosures, cancellation windows, deposit limits and licence display all vary, and some trades carry extra rules. Adapt this, then have a lawyer in your state review it before you put it in front of a customer.

What a insulation contract has to settle
An insulation contract has to commit to an R-value per area and to the evidence that it was achieved — depth markers or bag count, both of which belong in the contract as deliverables. Air sealing is the work that determines whether the insulation performs and the first line dropped to win a price, so it needs itemising as scope rather than described as included. Ventilation must be verified before depth is added, or the job creates a moisture problem. Rebate programmes often dictate exactly what the paperwork must show.
Clauses it needs
- Parties, licence number, and the areas in scope by square footage
- R-value committed per area, stated explicitly
- Evidence of installed value: depth markers or bag count, as a deliverable
- Air sealing itemised as scope, not described as included
- Baffles, and verification that soffit ventilation is adequate before adding depth
- Material and method: blown, batt, open or closed-cell foam
- Removal and disposal of existing material, where in scope
- Ignition or thermal barrier where code requires it
- Rebate or utility programme requirements the paperwork must satisfy
- Occupancy: re-entry time after foam, and ventilation during curing
What insulation contracts actually get argued over
- No depth markers or bag count, so the installed R-value cannot be shown
- Air sealing assumed included, not itemised, and later believed skipped
- Rebate rejected because the documentation lacked a required detail
- Soffits blocked by new depth, producing a moisture callback
The estimate this contract is built on
A contract can only be as clear as the scope it references. BidWand drafts the itemised estimate — labour, materials, exclusions and assumptions — that the scope and exclusions clauses point at.
Draft the insulation estimate this contract references
This generates the estimate, not the contract — describe the job and you get the itemised scope to attach. No email needed to see the first 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.
