How can you tell your house needs better insulation?

  • Hot rooms upstairs

    By late afternoon the bedrooms upstairs or the room over the garage feel much warmer than downstairs, and the AC never seems to catch up. That usually means the attic has thin insulation, gaps that let hot attic air drift down, or both. The longer it goes, the more of every summer power bill goes to cooling the attic instead of your rooms.

  • Drafts and cold floors

    You feel air moving near outlets, the attic hatch or the can lights, or the floors stay cold all winter. Air is slipping through gaps that insulation alone won't stop, and sometimes the crawl space under the floor has little or nothing in it. Left alone, the heater works harder every winter and dust keeps finding its way inside.

  • Old insulation you don't trust

    You look up through the hatch and see flattened batts, water stains, droppings or a loose fill you can't name. Old material that got wet or filled with pests has to come out, and some older loose fill needs checking before anyone disturbs it. Piling new insulation on top just hides the problem, and you end up paying for the job twice.

What does insulating a Pasadena home actually involve?

Home insulation in Pasadena means closing the air leaks between your attic and the rooms below, then adding insulation over them, so the house has fewer drafts and the heating and cooling bills can come down. At QuietCore Pasadena Spray Foam Insulation we're based in Pasadena and do this work across the city and the cities around it, including Glendale, Burbank, Arcadia and Altadena.

Most people call me because the upstairs is hot by afternoon, the house feels drafty, or there's old insulation up there they aren't sure about. The price mostly moves with the size of the attic, how much sealing it needs, whether the old material can stay, and which material suits your house. The schedule turns on the same things, plus anything that has to be fixed before new insulation goes in, like a roof leak or old wiring. If your job needs a permit, we find out whether the city or the county covers your address, then pull it and handle the inspection ourselves.

How we handle home insulation, starting in the attic

Most homes start with the attic, so I go up and look at what's there now, how deep it is, whether it's been wet or chewed through, and what runs across the joists, like ductwork or old wiring. If the old insulation looks questionable, we sort that out before planning anything new, because insulation laid over a leak or bad material only hides it. Then we plan the sealing and insulating as one job, so our crew seals the gaps around can lights, pipes, wires and the hatch, keeps the eave vents clear so the attic can still breathe, and lays the new insulation evenly out to the edges, where it's usually thinnest. When the ducts run through the attic, closed-cell foam, a dense foam that seals and insulates in one pass, can be worth its higher price, but in most houses sealing the gaps and topping up with blown-in fill, loose insulation blown through a hose, does the job for less.

Some houses need work beyond the attic. If the old material is soaked, full of droppings or crushed flat, insulation removal clears it so the new layer starts clean. If the floors stay cold even with a good attic, crawl space insulation under the house is usually the missing piece, and I'll tell you on the visit whether it's worth doing now or later.

Work that often goes with it

  • Insulation removal

    When what's in your attic has gotten wet, gone flat or become a nest, it has to come out before anything new can do its job.

  • Crawl space insulation

    For raised-floor houses where the cold comes up through the floor no matter what the attic has.

Questions about home insulation, answered

How much does home insulation cost in the Los Angeles area?

Installing insulation in the Los Angeles area usually costs about $2 to $7 per square foot of area covered. That spread is why a big attic with lots of sealing lands far from a small one that only needs a top-up. I'll give you your own figure in writing after I've seen the attic.

Does Pasadena Water and Power have a rebate for attic insulation?

Yes, Pasadena Water and Power pays back $0.10 per square foot for upgraded ceiling insulation, plus another $0.05 per square foot when you use a qualified local contractor or buy in Pasadena. It's for residential PWP electric customers, the new insulation has to bring the ceiling to R-30 or higher, R-value being how well insulation slows heat, and it's limited to one rebate per property every 15 years. The utility's Home Improvement Program is the other route, but people who get insulation through it can't also take the rebate, so check the utility's rebate page for the full terms before you choose.

What happens if my attic has vermiculite insulation?

Work stops, because federal attic guidance says not to go ahead over vermiculite, and the EPA advises treating it as if it contains asbestos. You can leave it undisturbed or have it removed, and the EPA says removal should be done by a trained, accredited asbestos abatement contractor separate from whoever assessed it. If I see it on my visit, I'll tell you plainly, and we plan the rest of the job around what you decide.

What is the best way to insulate an attic in an older Pasadena house?

Do it in order, which federal guidance lays out as making sure gas appliances vent safely and the house still gets fresh air, then attic ventilation, then air sealing, and only then insulation. Sealing comes before insulating to get the most energy savings, since insulation can't stop air that's moving through a gap. Done that way, it also helps keep moisture, dust and pests out of the house.

How do I deal with knob and tube wiring before insulating my attic?

Have it replaced or properly boxed first, because federal attic guidance says insulation goes in only after any active knob and tube wiring is dealt with. That makes the electrical work, done by an electrician, the first step of the project. If I spot it on my visit, I'll point it out, and the estimate puts the insulation after that work.

Does an insulation contractor in Pasadena need a license?

California's contractor licensing board has its own classification for insulation contractors, covering anyone who installs insulating material for temperature or sound control. The city also requires a business license for every contractor who pulls permits there. We're licensed and fully insured.
