Attic air sealing for Sun Valley homes
Attic air sealing in Sun Valley closes the joints and holes in the ceiling between your attic and the rooms below, which saves energy and helps keep moisture out of the attic. Prime Sun Valley Spray Foam Insulation does it for drafty homes and ahead of new insulation.
If the upstairs runs hot, the room over the garage feels off or the power bill keeps creeping up, the attic ceiling is usually part of it. Warm air slips up through gaps around can lights, pipes, wires and the attic hatch, and outside air gets pulled in behind it. Your price turns on how many of those openings there are, how hard the attic is to get around in and how much old insulation sits on top of them.
The schedule turns on anything that has to be fixed before we seal, which I'll point out when I see the attic, and on paperwork. Washoe County requires a building permit for any project that isn't on its exempt list, so before work starts we check whether your address falls under the county or a city and take care of the permit when your job calls for one. My written estimate lays out what I'd do first and what it costs.
Attic air sealing, safety checks and getting ready for insulation
Problems we sort out first
Before we seal anything, I look at the roof, the bath fans and any gas appliances, because sealing over a problem just traps it in your house. The Department of Energy's attic sealing guide holds off on the work when there's live knob and tube wiring, the old exposed kind, vermiculite insulation or bath fans blowing into the attic. A leaking roof or an unvented kerosene heater or gas fireplace waits on its own fix too. I'll tell you which of these apply to your house and what to plan for.
Closing the gaps in the ceiling
Once the attic is ready, our crew works across the ceiling, sealing the joints and the holes cut for pipes, wires and the hatch. The guide adds solid blocking over big holes and open soffits, and covers over can lights that aren't rated for airtight insulation contact. It matches material to the gap, with caulk for small cracks, foam for medium and large ones and a stiff infill that won't sag for the biggest, and it seals flues with fire-rated caulk and rated collars or sheet metal, kept clear of anything that burns. Ask us which we plan for your attic.
Vents kept open, attic ready
Some openings are supposed to be there. Soffit vents under the roof overhang, ridge and gable vents and combustion air ducts have to stay open to work, and buried eave vents are how an attic stops breathing and moisture shows up in the framing. With the ceiling sealed, the attic is ready for retrofit insulation. Spray foam insulation costs more and seals air while it insulates, but sealing the gaps and topping up loose fill usually wins unless your ductwork runs through the attic.

Attic air sealing questions from Sun Valley
Should my attic be sealed before new insulation goes in?
Yes, seal first. The federal attic sealing guide finishes the air sealing before any insulation goes in, because that order saves the most energy. Once fresh insulation is down, the gaps under it are buried and much harder to reach, so if you're planning insulation, book the sealing ahead of it.
Is attic air sealing safe with a gas furnace or water heater?
It can be, once the appliances are checked. Where a furnace, boiler or water heater uses a natural draft, meaning it vents up the flue on its own, the guide calls for a backdraft test and carbon monoxide detectors. It calls swapping those units for sealed combustion or power-vented models the best approach, an upgrade worth weighing alongside the sealing.
Does sealing the attic help with radon in Sun Valley?
It can cut how much soil gas gets pulled into the house. Gaps in the attic ceiling let air escape out the top, which draws air up from the ground, and sealing them weakens that pull. The state health division reports elevated radon in Nevada homes, recommends testing every home and says testing is easy.
How much does attic air sealing cost in Sun Valley NV?
Weatherization work in Reno usually costs about $550 to $5,300 per project, and that's the area's going rate, not our price. Where your attic lands depends on how many gaps there are, how easy it is to work in and whether anything has to be fixed first. I give you your own figure in writing after I've seen the space.
