Kinds of attic air sealing we do
Sealing, then topping up loose fill
Most attics get the gaps sealed and then a top-up of blown-in insulation, loose fill blown through a hose, over the sealed floor, which usually wins on cost.
Foam where ductwork runs overhead
Spray foam costs more and seals air while it insulates, so it usually earns its place when your ductwork lives up in the attic.
What does attic air sealing do for a drafty house?
At Reliable Kennewick Insulation Services, attic air sealing in Kennewick, WA means closing the gaps in your attic floor around the tops of walls, recessed lights, plumbing vents, exhaust fans and chimneys, so heated or cooled air stops escaping up through the ceiling.
Most people call us about a room that's always cold, an upstairs that bakes all summer or bills that keep climbing, and the attic is often where that air is getting out. The price moves with how many openings there are, how hard they are to reach and whether old insulation has to come off first, and the schedule turns on whether anything up there needs fixing before we start. If the inches already up there are thin, attic insulation goes over the sealed floor afterward, and your estimate writes out what we'd do and why.
Attic air sealing and the work around it
I look at what's in your attic now and what it's covering. That tells us whether sealing alone does it, retrofit insulation should follow, or spray foam insulation makes sense because ductwork runs up there.
Checking the attic first
Before anything gets sealed, we look for soaked or dirty old insulation and droppings, because new work over old trouble just keeps the problem.
Sealing the hidden openings
We seal around the tops of walls, light fixtures, pipes and fans before insulation goes over them, since that's where air slips through.
Matching material to the gap
Small cracks get caulk, rated for high heat near a flue or chimney, and wider holes get foam that fills them.
Keeping the vents clear
The soffit vents under the eaves, ridge vents and gable vents are meant to stay open, so we leave them clear and the attic keeps breathing.

Questions about attic air sealing
How much does attic air sealing cost in Kennewick?
Professional attic air-leak sealing across the US usually costs about $250 to $750 per job, and that's a national figure for the sealing itself, not our price. Complex work, testing, adding insulation and restoring finishes afterward can add substantially to it. I come out and write a free estimate with your own figure.
What attic problems have to be fixed before air sealing?
A Department of Energy attic air sealing guide says not to go ahead when the attic has active knob and tube wiring, vermiculite insulation or bathroom fans vented into the attic. The same guide also lists a leaking roof, an unvented kerosene heater or a gas fireplace, so those are worth looking for at home before you ask for a quote.
How does a gas furnace or water heater change attic air sealing?
The same guide says homes with gas- or oil-fired furnaces, water heaters or boilers on natural draft chimneys, the kind that rely on rising heat to carry exhaust out, need combustion air from outside. It also calls for a backdrafting test, a check that exhaust goes up the chimney instead of spilling back in, so plan on testing as part of the job if you have this equipment.
Should I seal my attic before adding insulation?
Yes, because loose fibrous insulation on its own isn't a dependable air barrier, and air moving through it carries heat right past it. The guide's order is combustion safety and indoor air quality first, then attic ventilation, then sealing, then insulation, so if you're planning new insulation, book the sealing first.
How do I know if my attic air sealing worked?
You can ask about a blower door test, a fan set in a doorway as part of a whole-house test-out, which may help show whether the duct and flue openings into the attic were sealed. An infrared camera used with it can find leaks when the house and attic are far enough apart in temperature. Our work is satisfaction guaranteed.
How long does attic air sealing take?
The time turns on how many openings your attic has, how much old insulation sits over them and whether anything has to be fixed before we start. I'd rather tell you once I've been up there than guess from the driveway.
Work that often goes with it
Retrofit insulation
Once the attic floor is sealed, adding insulation to a finished house is the next step for rooms that still run cold in winter or hot in summer.

When ductwork sits in the attic or a space needs sealing and insulating in one layer, foam handles both jobs at once and costs more for it.

If the inches already up there are thin or packed down, a fresh, even layer over the sealed floor is what slows heat moving through your ceiling.

For electrically heated homes, Benton PUD offers an insulation rebate of $0.06 to $2.00 per square foot, credited on the contractor's invoice, with an approved insulation contractor doing the work and sending in the application. Since the sealing comes before the insulation, it's worth reading Benton PUD's residential rebates while you plan both.
Washington requires every construction contractor to register with the state Department of Labor & Industries and to be bonded and insured, and the state's contractor lookup lets you search by name, license or UBI number before you hire anyone. We're based in Kennewick and work across the cities around it on both sides of the state line. In Pasco and Richland we open plenty of attics where recessed lights, wall tops and bath fans were never sealed, so we seal them the same way there.
