Is it urgent?

Can wait

Not urgent. The thing to watch is not urgency but verification: loose-fill is sold by the bag and delivered by depth, and the two only match if somebody checks. Ask for depth markers.

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

  • An open attic floor with thin, settled or missing insulation
  • Existing batts with visible gaps around joists, wiring and penetrations
  • Joist tops visible above the insulation line
  • An attic that has been worked in repeatedly and has insulation compressed into paths
  • Wanting to add over existing insulation rather than remove it, where the existing material is dry and clean

How the work is done

  1. Air sealing the ceiling plane first, since loose-fill does not stop air movement through a penetration
  2. Baffling the soffits before blowing, because loose-fill will otherwise block the intake vents
  3. Installing depth markers and blowing to a measured depth across the whole area, including the awkward perimeter
  4. Dam and insulate the attic hatch, which is a large uninsulated hole in an otherwise finished job

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. Ask for depth markers and a photograph of the finished depth in several places, particularly at the perimeter. Bag count is what you are billed on; depth is what you actually bought.
  2. Have the air sealing done first and itemized, not bundled invisibly into a price per square foot.
  3. Clear anything stored in the attic — it will otherwise be buried or moved onto the finished insulation.
  4. Ask whether the attic hatch is being dammed and insulated. It is small, cheap, and usually skipped.

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.

What does Blown-In 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.
