What does attic air sealing do for a Richland house?
Attic air sealing in Richland closes the holes between your attic and the rooms below, so the warm or cool air you pay for stays downstairs instead of slipping up and out. The large gaps make most of the difference, so that's where the work goes.
Most people call us because a room is drafty, the upstairs runs hot or the power bill keeps climbing, and they figure the fix is more attic insulation. Often the air getting through comes first. The price turns on how big your attic is and how easy it is to move around in, how many large gaps it has, and whether anything has to be repaired or pulled out before we seal. The schedule depends on those same things, plus a draft check if anything in the house burns fuel. I'll give you a written estimate that lists each step in the order we'd do it, so you have your own answer instead of a guess.
How can you tell your attic is leaking air?
Rooms that won't stay comfortable
Maybe the upstairs runs hot, the room over the garage stays cold or one end of the house never matches the thermostat. That usually means air is moving through gaps into the attic, and until it's stopped you keep paying to heat and cool air that leaves.
A power bill that keeps climbing
Heating and cooling can cost more each year even when you haven't changed how you live, and leaks are a likely cause. Adding insulation on top won't fix that, because air keeps moving through the gaps underneath it.
Ice dams, dry air and dust
Ice along the eaves in winter, indoor air that feels dry and dust that comes back right after you clean can all point to air moving between the house and the attic. Any one of these is reason enough to have the attic looked at before the bills or the moisture add up.
How we handle attic air sealing
Before anything gets sealed, I check the attic for problems that have to be fixed first, like wet insulation, moldy or rotted rafters, a fan venting into the attic instead of outside, too little ventilation or knob and tube wiring, the old cloth-wrapped kind, because sealing over any of those just hides it. Then we spend our time where the big leaks hide, which is where the wall tops meet the attic floor, above dropped ceilings like the boxed-down areas over cabinets, and behind or under kneewalls, the short walls along the sides of an attic room. Around a flue or chimney the seal has to be a heat-resistant material such as sheet metal, so nothing there can catch fire. We finish with the hatch, the pipes and the can lights, and we keep the eave vents clear so the attic can still breathe.
Sealing is often the first step of a bigger job. In an older house it usually leads into retrofit insulation, adding insulation to a home that's already built and lived in. When an attic is better served by foam than by loose fill, that's our spray foam insulation work.
Seal the gaps, then top up loose fill
This suits most attics we see, because closing the gaps and then adding blown-in insulation, loose fill blown through a hose, gets you most of the comfort for less than foam. We keep the fill even all the way out to the edges, where attics are usually thinnest.
Foam where the ductwork runs
Foam costs more, but it seals air while it insulates, so it earns its price when your heating and cooling ducts run through the attic. If your house doesn't need it, I'll tell you the simpler way will do.

I look at your attic myself

Learned in attics, running since 2023
I started hauling bags into attics as a kid and worked beside my dad for years before starting this business in 2023. He taught me that the part nobody sees still has to be done right, and in air sealing that's nearly all of it.

Attic air sealing and insulation help around Richland
If money is tight, check one thing before you hire anyone. Benton Franklin Community Action Connections provides free weatherization and energy assistance to income-qualified families and individuals in Benton and Franklin counties, and I'd rather you find out whether you qualify than pay for something you could get free.
We're based in Richland and work across the Tri-Cities and the cities around it, including some across the state line in Oregon. The leaks look much the same from house to house, whether it's open wall tops and unsealed can lights in an older ranch house or a bonus room over the garage with kneewalls nobody sealed, and we find the same patterns on jobs in Kennewick and West Richland.
Questions about attic air sealing in Richland
How much does attic air sealing cost in Richland, WA?
There's no set price, because it depends on how much there is to seal and what has to be fixed first, and I only know that once I've been up there. An attic with easy access and dry, clean insulation costs less to seal than one with soaked or dirty fill to clear out or a flue to frame in sheet metal. If you might qualify for the county weatherization help mentioned above, check that first.
What is the best way to air seal an attic before adding insulation?
Seal first, then insulate. Federal guidance on attic air sealing puts combustion safety and indoor ventilation first, then attic ventilation, then sealing, with insulation going in last, and ties that order to the most energy savings. We work in that order too, because insulation laid over an open gap only hides it.
Is attic air sealing safe if I have a gas furnace or water heater?
It's safe when the draft is checked before and after, and that's what we plan for any house with fuel-burning appliances. In some cases a tighter house can make an appliance that vents on its own natural draft pull exhaust back into the rooms, so the second check confirms everything still vents the way it should.
What should I do if my attic has vermiculite insulation?
Leave it alone until an approved lab has tested it for asbestos, which is ENERGY STAR's advice for vermiculite, the gray-brown, pebbly fill. Your local health department can name an approved lab. Mention it when you call, so I can plan the job around it.
How long does attic air sealing take, and do we have to leave the house?
Most families can stay home while we seal, because the work happens in the attic and we mostly pass through the hatch. How long we're up there depends on the attic's size, how easy it is to move around in and whether repairs come first, and I'll tell you what to plan for at the estimate. If foam is part of the job, there's a re-entry time, a wait before you come back in, and we go over it with you before we start.
How do I check an insulation contractor's license in Washington?
Look them up with the Washington State Department of Labor & Industries, which lets you confirm a contractor's registration, bond and insurance. The state requires every construction contractor to register with L&I and to be bonded and insured, so it's worth checking before anyone climbs into your attic.
Insulation work that often goes with air sealing
Retrofit insulation
If your walls have thin insulation or none, retrofit work adds it while you live there, and sealing the attic first helps it do its job.
Spray foam insulation
When heating and cooling ducts run through the attic or a space can't hold loose fill, foam stops air and insulates in the same layer.
