How can you tell your old attic insulation should come out?

  • Droppings or nests up there

    Droppings, shredded paper or tunnels through the insulation usually mean rodents have been living in it, and the smell can drift down through the ceiling. The longer it sits, the worse it gets, and new insulation laid on top only covers the problem.

  • Water stains or matted patches

    Brown stains or insulation that's gone flat and crusty usually point to an old roof leak, and packed-down insulation doesn't slow much heat. If it stays, it can hold moisture against the framing, and topping it up just hides where the water came in.

  • Thin, patchy or dirty insulation

    If you can see the tops of the ceiling joists, or the insulation is deep in the middle and bare at the edges, your house is losing heat both ways, and that usually shows up as a hot upstairs and a higher power bill. When the old layer is too dirty or uneven to build on, taking it out gives you a clean start.

Should old attic insulation come out before new goes in?

Insulation removal in Pasadena means our crew takes the old insulation out of your attic, with a vacuum hose where we can reach and by hand in the tight spots, so whatever goes in next sits on a clean attic floor and not on an old leak or a rodent problem.

Most of the calls I get for this come from someone who's been up the attic ladder and didn't like what they saw, or who wants new insulation and isn't sure the old layer can stay. At QuietCore Pasadena Spray Foam Insulation, the price and the schedule turn mostly on your attic's size, how easy it is to get into, what the old material turns out to be and whether rodents have to be trapped out first, and the written estimate puts all of that in the order we'd do it. We're based in Pasadena and work across the city and the cities around it, including Glendale, Burbank, Arcadia and Altadena.

Details to note before an estimate

  • Rough square footage of the attic
  • Where the attic hatch is
  • Any droppings, nests or odd smells
  • Color and texture of the old insulation

How we handle insulation removal

Before anything comes out, I check what the old material is and whether rodents have been living in it, because that decides everything that follows. If it looks like vermiculite, we leave it alone and point you to a licensed abatement contractor, since that isn't work for an insulation crew. On a regular job, our crew covers the path from the hatch to the door, then pulls the old insulation with a vacuum hose where we can reach and by hand along the low edges, so the eave vents come clear too. With the attic bare, I look for roof leaks, old wiring and open gaps around pipes, lights and the hatch, and I tell you plainly what I find before anything new goes over it.

Removal is usually the first half of the job, and a bare attic is the easiest time to seal those gaps and put new insulation in. For what goes back, I usually lean toward sealing the gaps and laying blown-in fill, loose insulation blown through a hose, because foam costs more and mostly earns it when your ductwork runs through the attic. If the floors stay cold too, crawl space insulation is often the next thing worth a look, and in older houses where the walls were never filled, wall insulation takes care of the rooms that stay drafty after the attic is done.

Work that often comes after removal

  • Crawl space insulation

    If the downstairs floors feel cold or the house smells musty from below, the crawl space is often where the heat is slipping out.

  • Wall insulation

    Plenty of older houses have empty wall cavities, which is why some rooms stay hot or drafty even with a good attic overhead.

    Call (626) 345-7649 or use the form, and we'll set a time for me to come out. If you've seen droppings or pebbly fill up there, mention it so I know what to look for.

  2. I check the attic with you

    I go up, look at the old material and any signs of rodents, and walk you through what I see. You get a written estimate that lays out what comes out, what gets fixed and in what order, so you can see what's driving the price.

    Our own trained crew handles the removal and the cleanup, and the date waits on trapping if rodents turned up. When the crew's through, I go over the bare attic with you before we call the job finished.

Questions before you book insulation removal

How much does attic insulation removal cost in the Los Angeles area?

Attic insulation removal in the Los Angeles area usually costs about $2,000 to $6,000 per project, and that's the going range around here, not a quote from us. Where a job lands depends mostly on the attic's size, what the old material is and how hard the space is to reach, since a tight attic often means removing by hand, which takes longer and costs more. Your written estimate gives you the figure for your own attic.

How long does it take to remove old attic insulation?

It usually takes anywhere from about 4 hours to 2 days or more, depending on how big the attic is and how complicated the job gets. A small, open attic sits at the short end, while a big one with low edges or a rodent cleanup runs longer, so you can plan around the size of your own.

What should I do if my attic has vermiculite insulation?

Leave it alone, because the EPA advises treating vermiculite as if it contains asbestos and not disturbing it. It looks like small loose pebbles, usually gray-brown or silver-gold, poured between the joists. If you decide to have it taken out, the EPA says a trained and accredited asbestos abatement contractor should do it, one that's independent from whoever assessed it so there's no conflict of interest, which is why we send that job elsewhere.

How do I deal with mouse droppings in my attic insulation?

Get the rodents out first, because cleanup guidance says the infestation has to be trapped out completely before the attic is cleaned. Once there's no sign of them, the guidance calls for waiting about 5 days, so the removal date comes after the trapping and that wait. I look for droppings and nesting at the estimate, and the written plan puts those steps in order.

How do I check that an insulation removal company is properly licensed in California?

Ask for their license, and if the job could involve asbestos, make sure they're cleared for it, because the state requires a C-22 asbestos abatement classification for work on 100 square feet or more of asbestos-containing material, or a license qualifier who passed the asbestos certification exam. Asbestos contractors also have to be registered with the state for work that size, and you can look them up on the state's asbestos registrants' database, though a just-expired registration can still show there, so ask whether it's current. We're licensed and fully insured, and vermiculite is a job we hand to abatement contractors.

Do I need a permit to remove attic insulation in Pasadena?

It can, and we find out for you before work starts by checking whether the city or the county covers your address. If your job needs a permit, we pull it and take care of the inspection that goes with it. The City of Pasadena requires any contractor who pulls permits there to hold a city business license, so it's a fair thing to ask anyone you're comparing, and the South Coast AQMD sets its own survey, notification and work rules for asbestos during renovation and demolition.
