How to write a insulation estimate

A professional insulation estimate builds client trust and reduces disputes. Here's what to include:

1. Break the job into line items

List each task and material separately — don't just quote a lump sum. For a insulation job, this means separating labor from materials, and calling out specific items (e.g., "Air Sealing (attic penetrations)"). Clients who can see the breakdown approve faster and dispute less.

2. Price each line item

Enter a unit price and quantity for each line. If you're charging by the hour, list the hourly rate and estimated hours. Being specific lets you defend your price if a client questions it — and shows you've thought the job through.

3. Include your business header

Put your business name, license number, phone, and email at the top. Many homeowners check license numbers before approving. A professional header signals you're legitimate — crucial if you're bidding against unlicensed competitors.

4. State validity and terms

Most insulation estimates are valid for 30 days. Note that in the document, along with any deposit required before work starts. This protects you from clients circling back months later expecting the same price.

5. Make it easy to approve

Sending a PDF is fine, but clients who can approve with one tap convert faster. ProposalHammer sends the estimate as a link — clients open it on their phone, read it, and tap "Approve." You get notified instantly and can schedule the job right away.
