What is a insulation installation contract?
Insulation is out of sight once it's in, which is why the paperwork matters. An insulation installation contract records the material, the depth or thickness and the rating the customer is paying for, and what the installer will do about ventilation, old insulation and anything unpleasant found in the attic.
This template covers attics and lofts, walls, crawl spaces and cavity walls, in blown-in loose fill, batts, spray foam, rigid boards or a combination. It records the areas, the product, depth and rating, an editable list of air sealing and preparation, and whether old insulation is left, removed in the price or removed for a separate price. It has a stop-work rule for suspected asbestos, mould, pests, leaks and unsafe wiring, a ventilation and moisture clause, and a re-occupancy clause that appears when spray foam is chosen. It also sets the customer's access and clearing duties, the price, deposit and installation date, an optional rebate clause that keeps the scheme's decision separate from the price, and a workmanship warranty that makes no promises about energy savings.

Using the insulation installation contract, step by step
1 Describe the work
Enter the areas, choose the material and method, and quote the product, depth or thickness and rating as the manufacturer states them.
2 Old insulation and preparation
Choose whether old insulation stays or is removed, add a removal price if separate, and edit the pre-filled air sealing and preparation list.
3 Price and rebate
Enter the price, an optional deposit and the installation date. Name any rebate scheme the customer is applying for to add the paperwork clause.
4 Warranty and send
Set the workmanship warranty in months and the governing law, then send it to the customer to sign.
Tips before you send it
- Photograph the attic before and after, with the depth markers visible. Rebate schemes often ask for exactly that.
- Never disturb vermiculite or other material that may contain asbestos. The contract has you stop and the customer arrange testing.
- Check that bathroom and kitchen fans vent outside, not into the attic. Insulating over them can trap moisture.
- Some rebate schemes only accept registered installers or specific products. Check the scheme's rules before you quote.

Insulation installation contract: frequently asked questions
Does the contract promise lower energy bills?
No. It records the product, depth and rating installed and warrants the workmanship, but states that savings depend on the whole building, its heating and how it's used.
What happens if the installer finds asbestos or mould?
The installer stops work in that area and tells the customer. Testing, specialist removal and repairs aren't included and must be arranged before work continues there.
Who gets the rebate?
The customer applies and the installer provides the invoices, photos and records the scheme asks for. The scheme decides whether to pay, and unless agreed otherwise the customer pays the full price either way.
What about spray foam safety?
If you choose spray foam, the contract adds a clause keeping the household out during spraying and for the manufacturer's re-occupancy period, which the installer gives in writing beforehand.
Can I sign it electronically?
Yes. E-signatures are generally valid for home improvement contracts in the US, UK, EU and Canada, though some places add notice rules for contracts signed at home. FileIt keeps an audit trail with the signed PDF.
