Get free quotes from local installers

Tell us what you need done and where. We pass it to insulation professionals who cover your area, and they come back to you with prices.

One request, several prices

Three quotes is what tells you whether the first one was fair. One form instead of three phone calls.

Your numbers come too

The area, R-value target and material from the calculator go with the request, so a quote starts from real figures.

No obligation, ever

Compare what comes back and walk away if none of it suits. There is nothing to sign here.

How installers reach you

This is the only part we need from you.

See our privacy policy. We never sell your details to anyone outside this request.

Free, and no obligation to hire anyone.

What happens after you submit

  1. Your request reaches us immediately, with the project details you entered.
  2. We match it against insulation professionals who cover your ZIP code and do the type of work you need.
  3. They contact you directly to arrange a look at the job and give you a price. Most call within a couple of business days.

We are not a contractor and we do not do the work ourselves. We are paid by the professionals and lead services we pass requests to, which is how the calculators on this site stay free — see our disclosure.

Prefer to do it yourself?

Plenty of insulation work is a genuine weekend job, and we would rather tell you that than sell you a contractor you do not need. The calculators price both routes side by side, and the shopping list has everything a DIY attic job needs.

Before you talk to anyone

Knowing your target R-value and roughly how much material the job takes is the difference between comparing quotes and guessing. Our guide to getting good quotes covers what a quote must include and the questions worth asking.
