Gaps in your attic floor send your cooled air straight up and let desert heat pour down. We find and seal every opening so your AC stops fighting your own house.
Attic air sealing in Sun Valley means finding and closing every gap, crack, and opening in your attic floor so conditioned air stays inside your home where it belongs. Most jobs are done entirely from inside the attic using foam and caulk, with no exterior work and no drywall removal - and most homes are finished in two to six hours.
If your home sits in Sun Valley and your electric bills spike every June, air leaking out of your living space and into the attic is one of the most likely causes. Insulation slows heat transfer through solid surfaces, but it cannot stop air from moving through gaps. Sealing those gaps first is what lets the insulation do its job. For the most complete solution, many homeowners pair attic air sealing with full-home air sealing services to address every pathway at once.
If your bill jumps dramatically in June or July - well beyond what you would expect from running the AC - air leaking from your living space into the attic is a likely cause. Sun Valley summers are long and hot, and an unsealed attic acts like a giant heat pump pulling your cooled air upward. If the bills feel out of proportion to your usage, an attic air sealing assessment is a reasonable first step.
Walk through your home on a hot afternoon and notice whether some rooms feel significantly warmer than others, especially those with recessed lights. Recessed light fixtures are one of the most common air leak points in older homes, and they sit right below your attic. If one end of the house is noticeably harder to cool, air movement through the attic floor is often the reason.
Sun Valley has fine alkaline desert dust that gets into everything, but if you are wiping down shelves and ceiling fan blades every week and the dust comes back quickly, your attic may be pulling in outside air loaded with particles. This is especially common in homes built in the 1970s and 1980s, where gaps around plumbing and wiring were simply never sealed.
Homes built in Sun Valley before modern building codes required air sealing were put up with gaps that were never addressed. If you have lived in your home for years and never had anyone look at the attic from an energy standpoint, there is a reasonable chance you are losing conditioned air every day without knowing it. An energy assessment will tell you exactly what is happening.
We approach every attic air sealing job by working through the attic floor systematically - sealing gaps around plumbing stacks, electrical wiring, top plates, recessed light fixtures, and the attic access hatch itself. These are the spots where most conditioned air escapes, and closing them is what creates real, measurable results. For homeowners who want to go further, we connect attic sealing to retrofit insulation so the attic floor is sealed and insulated in a single coordinated project, giving you the most complete thermal protection possible.
We also work alongside homeowners who have never had any energy work done and do not know where to start. If you want a full picture of what is happening in your home before committing to any specific scope, we can perform a complete assessment and present all the options. Every job includes a walkthrough of what was found and what was sealed, and we can document before-and-after results that are useful if you apply for a utility rebate through NV Energy or claim a federal tax credit.
Best for homes where conditioned air is escaping through gaps around wiring, pipes, and fixtures in the attic floor.
Right for homes with older can lights that open directly into the attic space and act as a direct air bypass.
Ideal for homes where the pull-down attic stair or access hatch has never been weather-stripped or insulated.
For homeowners who want to seal and add or replace insulation in the same visit for the best combined energy benefit.
Sun Valley sits at roughly 4,500 feet in the high desert northeast of Reno, where summer temperatures regularly push past 95 degrees and attic temperatures can climb well above 130 degrees during peak heat. When gaps connect that superheated attic space to your living area, your air conditioner is fighting a battle it cannot win - the load is too high and the leaks are too consistent. The problem runs in both directions: the same gaps that let cooled air escape in summer let warm air out in winter, making your heating system work harder on cold nights when temperatures drop below freezing. Homeowners in Sparks and Spanish Springs face identical conditions across the Truckee Meadows, and attic air sealing delivers the same benefit throughout the region.
A significant share of Sun Valley homes were built between the 1960s and 1980s, when energy codes did not require air sealing and contractors simply did not address attic gaps as a matter of course. Many of these homes have never had any sealing work done at all - the gaps that were there on day one are still there today. The high desert dust that blows in from the surrounding valley also uses these same openings to enter your home, which is why homeowners who seal their attics often notice cleaner air and less frequent dusting as a secondary benefit. For authoritative guidance on home air sealing, the U.S. Department of Energy air sealing guide and the ENERGY STAR seal and insulate program are both reliable references.
We will ask a few basic questions - your home size, when it was built, and what has been bothering you. You will hear back within one business day to schedule a free on-site visit. You do not need to know anything technical before this call.
We go into your attic and look at the current insulation, identify where the gaps and penetrations are, and assess how accessible the attic floor is. This visit usually takes 30 to 60 minutes, and we walk you through what we found before we leave.
You receive a written estimate covering exactly what will be sealed and what it will cost. We explain whether a blower door test is included and answer any questions about scope, timing, and rebate eligibility before you decide anything.
