Is it urgent?

Can wait

Not urgent, and the one on this list to be most skeptical about. Foam is excellent in the assemblies that need it and poor value in the ones that do not — and an open attic floor is usually the second case. If a quote proposes foam everywhere, get a second opinion.

Two things override everything on this page. If anyone has symptoms of carbon monoxide exposure — headache, nausea or dizziness that improves outdoors — leave the building and call the gas utility or the fire service, not a duct company. And if you can smell burning while the dryer is running, unplug it and leave it.

Signs to look for

  • A rim joist or band joist that needs insulating and air sealing together
  • A cathedral or vaulted ceiling with no room for a vent channel and batts
  • An unvented attic assembly where the roof deck itself is the thermal boundary
  • A wall or roof where the existing cavity cannot be dense-packed reliably
  • A quote proposing foam across an open, accessible attic floor, which is the case to question

How the work is done

  1. Choosing closed-cell or open-cell on the basis of the assembly and the vapor requirement, not on preference
  2. Confirming the roof assembly can be unvented before foaming a deck, since getting that wrong traps moisture in the sheathing
  3. Protecting the occupied space and observing the manufacturer re-occupancy time, which is not optional
  4. Covering with an approved thermal barrier where the code requires it, rather than leaving foam exposed

In California specifically

California's Mediterranean on the coast, hot and dry inland climate and its housing stock — stucco ranch and bungalow, tile or composition roofs, slab in the south and raised crawlspace through the Bay Area and the north — decide what is worth doing first. California is also the one state where duct leakage is routinely tested: Title 24 requires a HERS-verified duct test on most furnace or air-conditioner changeouts, so a duct problem here often surfaces as a failed test rather than as a complaint.

Before the technician arrives

Four things worth doing — and the first one is usually the thing people get wrong.

  1. Get a quote for batts or blown-in alongside the foam quote wherever the space is an open, accessible attic floor. If foam costs several times as much for the same R-value in the same place, that is the answer.
  2. Ask for the re-occupancy time in writing and plan to be out for it. It is measured in hours, not minutes.
  3. Ask specifically whether a thermal barrier is required and included. It is a code item and it is sometimes left out of the price.
  4. Never have foam sprayed over active moisture or unrepaired sheathing. It is permanent and it hides what it covers.

How it works

Three steps, and you decide at the end of them.

  1. 1

    You call and describe the problem

    Tell us what you have noticed and where — the room, the smell, the noise, how long it has been going on. Give us your ZIP code and we will match you to a licensed company covering your area. There is no form to fill in.

  2. 2

    A local company takes it from there

    They discuss the problem with you directly, arrange a time to inspect, and agree the work and the price with you before anything starts. That conversation is between you and them.

  3. 3

    You decide whether to go ahead

    You are under no obligation. If the quote or the approach is not what you wanted, you are free to say no and call someone else.

Spray Foam Insulation — FAQs

Do I actually need Spray Foam Insulation done?

Not urgent, and the one on this list to be most skeptical about. Foam is excellent in the assemblies that need it and poor value in the ones that do not — and an open attic floor is usually the second case. If a quote proposes foam everywhere, get a second opinion.

What makes this different in California?

California's Mediterranean on the coast, hot and dry inland climate and its housing stock — stucco ranch and bungalow, tile or composition roofs, slab in the south and raised crawlspace through the Bay Area and the north — decide what is worth doing first. California is also the one state where duct leakage is routinely tested: Title 24 requires a HERS-verified duct test on most furnace or air-conditioner changeouts, so a duct problem here often surfaces as a failed test rather than as a complaint.

Are the companies licensed and insured?

Yes. We only pass calls to licensed, insured operators working in California, and you are welcome to ask to see a license number on arrival.

What does Spray Foam Insulation cost?

It depends on the property, the size of the system and what the inspection finds, so we do not publish a price — a figure quoted on a web page is not one the attending company has agreed to. You get a price before any work starts.
