Gaps and cracks in your home's shell let conditioned air escape year-round. We find them, seal them, and show you the results with before-and-after testing.
Air sealing in Walla Walla means finding and closing the gaps, cracks, and penetrations in your home where outside air enters and conditioned air escapes, most jobs covering an average home in one to two days with work concentrated in the attic, crawl space, and around pipes and wires.
Many Walla Walla homes - particularly those built before 1980 in neighborhoods near downtown or around Whitman College - were constructed without the air barriers and sealing techniques used today. Every gap in your attic floor, every pipe penetration, and every unsealed top plate is a path for heat to escape in winter and push in during summer. The result is higher bills and rooms that never quite reach the temperature you set.
Air sealing works best when paired with insulation upgrades. If your attic has not been addressed, we offer attic air sealing as a focused service, and adding basement insulation below creates a complete thermal shell from top to bottom.
If your gas or electric bill spikes every time Walla Walla temperatures drop - and you have not added appliances or changed your thermostat - your home is likely losing heat faster than it should. Air escaping through gaps in the attic, walls, and around pipes is often the cause. Air sealing is usually the most cost-effective fix before you consider replacing your furnace or windows.
Hold your hand near an electrical outlet on an exterior wall on a cold day. If you feel cool air moving, that outlet connects to a gap running through the wall cavity to the outside. Drafts near baseboards and along window trim are the same signal. These are the types of leaks air sealing addresses directly.
Walla Walla is surrounded by wheat fields and vineyards, and late summer harvest brings elevated dust and particulates into the valley. If your home gets noticeably dirtier during harvest or on windy days, outside air is getting in somewhere it should not. Air sealing significantly reduces the pathways that dust uses to reach your living spaces.
If upstairs bedrooms are noticeably hotter in July and colder in January than the rest of the house, conditioned air is escaping through the attic above them. Corner rooms are also common problem spots because they have more exterior wall surface. These comfort complaints are almost always a sign of air leaks, not just an insulation issue.
We start every job with a diagnostic blower door test - a large fan temporarily placed in a doorway that pressurizes your home and reveals leaks that are invisible to the naked eye. This gives us a real measurement of how much air your home is losing, not just a guess. We seal gaps using the right material for each location: spray foam for small holes around pipes and wires, caulk for cracks along baseboards and window frames, and rigid foam or special tape for larger attic openings. We then run the blower door test again after the work so you can see the before-and-after numbers in writing.
We also offer attic air sealing as a standalone service for homeowners who want to focus on the part of the home where the biggest leaks typically hide. For a complete solution, basement insulation below and air sealing above work together to create a tight thermal envelope from foundation to ridge.
Best for homeowners who want a comprehensive assessment and sealing of all major leakage points throughout the house, with diagnostic testing before and after.
Suited for homeowners who already know their problem area - such as a leaky attic or a drafty crawl space - and want focused work in that zone without a full-house assessment.
Walla Walla's climate creates pressure on your home's shell in both directions. Winter lows can drop into the mid-20s Fahrenheit, while summer highs regularly exceed 100 degrees. Every gap in your home is either letting expensive heat out in January or letting brutal heat in during July. That two-season demand makes the return on air sealing faster here than in milder climates. Avista Utilities serves most Walla Walla homes and has historically offered rebates for air sealing work, sometimes requiring pre-approval before the job starts - so it is worth contacting them before you schedule. Homeowners in College Place face the same climate conditions and older housing stock, and we serve that area on the same terms as Walla Walla proper.
There is also a local benefit that goes beyond energy savings. The Walla Walla Valley is wine and wheat country, and seasonal agricultural activity - especially wheat harvest in late summer - generates elevated levels of fine dust. Homes with significant air leaks let that dust work its way inside through gaps around pipes, attic hatches, and unsealed wall penetrations. Sealing those pathways is one of the most effective things you can do to reduce indoor dust, especially during harvest months. Residents of Pendleton in the Umatilla Basin deal with similar agricultural dust conditions and can benefit from the same approach.
We ask a few questions about your home and what has been prompting the call. We reply within one business day and can usually schedule an initial visit within one to two weeks.
A technician visits your home, does a walkthrough, and runs a blower door test to measure how much air your home is leaking. This test gives a real number - not a guess - and takes about one to two hours with you present.
After the assessment, we explain what was found, give you a written estimate, and walk you through any Avista rebates your project may qualify for before the work begins.
The crew seals gaps using the right material for each location - foam, caulk, or rigid barriers. Most whole-home jobs take one to two days. We run the blower door test again at the end so you see a measurable before-and-after result before we leave.
Free estimate, blower door test included, and no obligation. We reply within one business day.
(509) 516-0681We run a diagnostic blower door test before we start and again when we finish. You leave with a written record showing exactly how much tighter your home is - not just our word that the job was done right. This is the standard for quality air sealing work, and we do not skip it.
Avista serves most Walla Walla homes and has offered rebates for air sealing work, but some programs require pre-approval before the job starts. We know the current rebate landscape and can help you navigate the paperwork so you do not miss savings you are entitled to. Avista energy efficiency programs are worth reviewing before you schedule.
Many Walla Walla homes were built before modern air sealing practices existed, and older construction has gaps that newer homes simply do not have. We know where to look - around old plumbing, wiring, chimneys, and attic hatches - in the homes common to this area. Building Performance Institute (BPI) standards guide how we approach diagnostic testing and sealing.
A tighter home needs to breathe on purpose, not by accident. After sealing, we check that your home still has adequate fresh air exchange. If a small ventilation adjustment is needed, we let you know - so you end up with a home that is both tight and healthy, not just sealed.
The combination of diagnostic testing, proper materials, and local rebate knowledge means you get real, measurable results - not just foam applied in obvious spots. Call or request a free estimate and we will show you exactly what we find.
