The attic insulation materials we install
Blown-in cellulose
Paper fiber, treated and blown in loose through a hose. It's dense and fills snugly around wires and framing, so it suits attics full of obstacles.
Blown-in fiberglass
Glass fiber blown in the same way and lighter for its depth than cellulose, so it suits ceilings that shouldn't carry extra weight.
What goes into insulating an attic in Kennewick?
Attic insulation in Kennewick, WA is a layer of blown-in fiberglass or cellulose laid over the ceiling below your attic, after the gaps in that ceiling are sealed, so less heat moves between your rooms and the attic.
Most people call about a room over the garage that won't warm up, an upstairs that's hot by afternoon or a power bill that keeps climbing. What moves the price is the size of the attic, how much insulation is already up there and what shape it's in, and how many gaps and ceiling lights need attention first. The schedule turns on the same things, since anything soaked or dirty has to come out and the sealing gets done before new material goes in. Your estimate spells out what your attic needs and why. We're based in Kennewick and work across the cities around it on both sides of the state line.
Attic insulation, from measuring to final depth
Before anything goes in, we measure what's already up there and check every ceiling light, because that decides the rest. If the cold runs past the attic, we'll talk about home insulation as a whole.
Measure what's up there
We check the depth and condition of the old layer, because soaked or droppings-filled material has to come out, not get buried.
Seal the attic floor
We close the gaps around pipes, wires and light fixtures before any insulation goes in, so the new layer isn't fighting a draft.
Choose the material
We choose cellulose or fiberglass to suit your ceiling and attic rather than out of habit, then put it in as blown-in insulation.
Even depth to the edges
Our installers carry full depth out to the eaves and far corners, where older jobs we open up are usually thinnest.
Why Kennewick homeowners call Reliable Kennewick Insulation Services

I come out to see each job myself, so the person who measured your attic and checked its lights is the one who checks the finished work.

Problems named before work starts
If the old layer is soaked, a ceiling light can't be covered or a leak needs fixing first, I'll say so plainly instead of insulating around it. Satisfaction guaranteed.

Questions about attic insulation
How much does it cost to insulate an attic in Kennewick?
Your price comes from the size of the attic and how much work comes before the new layer, so the written estimate is where you'll see your own number. Removing old material or sealing a lot of gaps raises it, and a clean attic that only needs topping up keeps it lower. Spray foam costs more because it seals and insulates at once, but for most attics sealing the gaps and topping up loose fill is the better use of the money, unless your ductwork runs through the attic, where foam can earn its cost.
How much insulation does my attic need?
That depends on what's up there now, because the guidance sets a lower target for an attic that already has some. For homes in climate zones 4 through 8, ENERGY STAR lists an R-value, the measure of how well insulation slows heat, of R60 for a bare attic and R49 where 3 to 4 inches is already in place. That's why the depth gets measured before anything else.
Is cellulose or fiberglass better for my attic?
Neither wins in every attic, because the shape of the attic and the condition of the ceiling decide it. One insulation guide favors cellulose where headroom at the eaves is short or where it costs less per square foot, and fiberglass over an old plaster or sagging ceiling or where the roof has leaked. Fiberglass lets water run through and can recover if a leak is fixed quickly, while wet cellulose mats down and loses its insulating value in that spot even after it dries.
Is it safe to cover recessed ceiling lights with insulation?
Not unless the fixture is rated for insulation contact. Burying a light that isn't rated for it traps heat, which can damage the wiring insulation, shorten the fixture's life or, in the worst case, create a fire hazard. That's the reason the fixtures get checked before any insulation goes near them.
How do I check that an insulation contractor is licensed in Washington?
Use L&I's contractor lookup to confirm a contractor is registered and has a valid bond and insurance. Washington requires every construction contractor to register with L&I, the state's Department of Labor & Industries, and to be bonded and insured, so look up anyone you're weighing before you sign.
How long does attic insulation take, and do we have to leave the house?
With blown-in fiberglass or cellulose you usually don't need to leave, since nothing has to cure and there's no re-entry time, the wait before you can come back inside, the way there is with spray foam. How long we're up there depends on the size of the attic and how much removal and sealing comes first, and I'll tell you what to expect when I write the estimate.
Other work that often goes with it
Blown-in insulation
If your attic just needs topping up, loose fill blown in over sound material reaches the corners and fills around framing that rolls can't cover cleanly.

Attic insulation in Kennewick and the cities around it
Washington's energy code spells out two steps that matter in an attic. In a vented attic with loose fill or batts, it calls for a baffle beside each eave and soffit vent that keeps an opening at least as big as the vent and runs up past the top of the insulation, and it calls for the hatch from the living space to be weatherstripped. It also asks for a baffle or dam wherever loose fill goes in, so it can't spill into the rooms below. We set the baffles before we blow anything in and weatherstrip the hatch, because a buried vent stops the attic from breathing and lets moisture show up in the framing, and a leaky hatch undoes the sealing we just did.
Around here we work in older homes with plaster ceilings and in newer houses with low roofs and tight eaves, and each one points us toward a different material and a different way into the attic. We see the same mix on jobs in Richland and Pasco, so the measuring and the fixture check come first there too.
