Blown-in insulation for attic floors

  • Blown cellulose

    Shredded paper treated to resist fire, blown loose across the attic floor. It packs into odd corners well and suits older attics with uneven framing or very little up there now.

  • Blown fiberglass

    Loose glass fiber blown across the attic floor. It's light on the ceiling and doesn't hold water, so it suits topping up an attic that already has fiberglass.

Is blown-in insulation the right fix for my Kennewick attic?

Blown-in insulation is loose fill, usually cellulose or fiberglass, blown through a hose into an even layer across your attic floor, and for many Kennewick houses with a thin or patchy attic it's the most direct way to slow the heat moving through the ceiling.

Most calls start with a hot upstairs, cold floors or a power bill that keeps climbing, and in an older house the thin attic floor is usually a big part of it. The price moves with the size of your attic, how many inches are already up there, how many gaps need sealing and whether old material has to come out first. The schedule turns on clearing the attic and on anything up there that needs fixing before we start, and your estimate writes out what we'd do and why, so you see your own figure before you decide.

Prep, sealing and blown-in insulation, in order

What your attic needs depends on what's up there now and what's leaking through the ceiling, and sometimes the answer is a wider look at your home insulation than the attic alone.

  • Clearing the attic floor

    We ask you to move stored boxes and things out first, so the fill can lie level across the whole attic floor.

  • Dealing with old fill

    Wet or droppings-filled material comes out first through insulation removal, since new fill on top only buries the problem.

  • Sealing the openings

    We seal around can lights, pipes, wiring and the hatch before blowing, so the fill isn't fighting air leaking up from the rooms.

  • Even depth to the edges

    Chutes at the eaves keep the fill off the vents so the attic still breathes, and we blow the edges as deep as the middle.

Blown-in insulation questions we hear

How much does blown-in insulation cost in Kennewick?

The price for your house comes from the visit, because what swings it most, like old fill that has to come out or a lot of openings to seal, only shows once I'm up there. Spray foam costs more because it seals air while it insulates, but sealing the gaps and topping up with loose fill usually wins unless your ductwork runs through the attic. We'll put the figure in writing after we look.

Can blown-in insulation go into my existing walls?

Usually yes, through drill and fill, a common method that blows insulation into each wall cavity through small holes near the top without tearing the wall open. The holes can go on the inside or the outside of the wall, so you can choose which side of the house the work happens from. Our wall insulation page covers that job.

What happens if my attic has vermiculite or knob and tube wiring?

One national attic checklist says work stops if the old fill is vermiculite, the gray-brown pebbly kind that may contain asbestos, and that insulation goes in only after live knob and tube wiring, the old cloth-covered wire run on porcelain knobs, is replaced or properly boxed in. Either one changes the plan before any new fill goes up. If I find it on the visit, I'll tell you plainly before we plan anything else.

How do I know if my attic needs repairs before insulation?

Look for water stains on the ceiling or roof boards, damp spots, sagging framing and signs of mice or other pests, because those need fixing before insulation covers them. The same national checklist has the attic inspected for leaks, moisture, structural and pest damage, and gives the homeowner a list of needed repairs before work begins. I look for all of it on the visit and write down anything that has to come first.

How do I check an insulation contractor in Washington?

Use the state Department of Labor & Industries, called L&I, which has tools to verify a contractor is registered and has a valid bond and insurance. Washington requires every construction contractor to register with L&I, and state law requires them to be bonded and insured. Look up anyone you're thinking of hiring before the work starts.

Do we have to leave the house while you blow in insulation?

Usually not, because the fill goes in from the attic and the dust stays up there with it. We lay covers between the door and the hatch, and keeping pets in a closed room while the blower runs makes the day easier on them.

Blown-in insulation around Kennewick and the state rules behind it

Washington's energy code decides whether open-blown loose fill suits your attic at all. It allows it where the ceiling slopes no more than 3 feet in every 12, which covers a flat ceiling, and where there's at least 30 inches of clear space from the top of the ceiling joist or truss up to the underside of the roof boards at the ridge. The code also calls for a dam, baffle or retainer, a short barrier, wherever loose fill goes in, so it can't spill into the rooms or slide from a higher part of the attic into a lower one. On the visit I check the slope and the headroom, and where your attic steps down or opens at the hatch, we build that barrier before we blow.

Around Kennewick we see plenty of older houses with a few thin inches on the attic floor, plus additions and rooms over the garage where the attic changes height. We meet the same houses on jobs in Pasco and Richland, and we handle them the same way.
