Kennewick winds push outside air through every gap in your home - and your furnace or AC pays the price. We find those leaks with a blower door test, seal them with foam and caulk, and prove the results before we leave.
Air sealing services in Kennewick identify and close every gap, crack, and opening in your home's outer shell - around light fixtures, plumbing stacks, rim joists, window frames, and wherever pipes or wires pass through walls. Most whole-home jobs take one to two days. The work starts with a blower door test that makes invisible leaks measurable, and ends with a second test that shows exactly how much the leakage rate improved.
Kennewick's Columbia Basin location means sustained winds are a regular part of life, and those winds push outside air through leaks far more aggressively than in calmer parts of Washington. Even homes with good insulation lose significant heating and cooling energy through air infiltration - which is why air sealing and basement insulation are often done together, since rim joists are among the leakiest spots in older Kennewick homes.
According to the U.S. Department of Energy, a typical home loses roughly 25 to 40 percent of its heating and cooling energy through air leaks. In a climate with temperature swings as wide as Kennewick's, that translates to a meaningful chunk of your utility bill going out through gaps you cannot see.
If you notice a chill near your baseboards, around outlets on exterior walls, or along the floor above an unheated space, that is outside air leaking in. In Kennewick's cold winters, this infiltration is especially noticeable because the temperature difference between inside and outside is large - and it means your furnace is working harder than it needs to.
When attic air leaks into the living space, it brings heat with it - and in a Kennewick summer, attic temperatures can reach extremely high levels. If your upper floor is consistently warmer than the rest of the house even with the AC running, air leaking down from the attic is a likely cause. Air sealing the attic floor is often the single most effective fix.
If your utility bills feel out of proportion to the size of your home or how you use your thermostat, air leakage is one of the first things worth investigating. Kennewick's extreme seasonal temperatures mean a leaky home pays a steep energy penalty year-round. A blower door test can tell you exactly how leaky your home is.
If your home seems to collect dust quickly - especially after a windy stretch typical of Kennewick's Columbia Basin location - that dust is likely entering through air leaks rather than just through open doors and windows. Sealing those entry points reduces how much outdoor air and particulate matter gets pulled inside.
We start every job with a blower door test - a fan mounted in your front door that depressurizes the house so leaks become visible and measurable. That diagnostic step separates targeted, effective work from guesswork. The biggest leaks in most Kennewick homes are in the attic floor - around recessed lights, plumbing stacks, and the gap where interior walls meet the attic. We address those first, then work through the basement rim joist, crawl space, and any other high-leakage zones found during the test. We pair whole-home air sealing with attic air sealing when attic bypasses are the primary source of heat loss - which is the case in the majority of Kennewick homes built before 2000.
We use foam, caulk, and rigid barriers depending on the size and location of each gap. Ventilation is always accounted for - sealing a home correctly means controlled fresh air, not zero fresh air. After sealing, we run a second blower door test to confirm the improvement and document the before-and-after numbers in writing. We also identify whether your project qualifies for Pacific Power rebates or federal tax credits through the Inflation Reduction Act, and we handle the contractor-side documentation so you are not chasing paperwork after the fact.
Full blower door diagnostic followed by sealing all major leakage zones - attic, rim joist, crawl space, and walls. Best for homes with multiple comfort complaints.
Targeted sealing of the attic floor bypasses that cause hot upper floors in summer and cold infiltration in winter. High-impact, single-day job.
Closes the gap between your foundation and framing - one of the most common and overlooked air leakage points in older Kennewick homes.
Sealing gaps and adding or upgrading insulation in the same project for homeowners who want the full energy performance improvement at once.
The Columbia Basin is one of the windiest residential environments in Washington State. Sustained winds of 15 to 25 mph are routine, and gusts in spring and fall regularly exceed 40 mph. That wind pressure forces outside air through every gap in your home's shell far more aggressively than it would in Seattle or Portland. The same crack that barely registers in a calmer climate becomes a significant energy drain here. Homes built in Kennewick before 2000 - which represent a large share of the city's housing stock - were constructed without the air barriers that modern energy codes require, so they tend to be especially leaky.
Air sealing also directly reduces dust infiltration, which is a quality-of-life concern specific to the Columbia Basin. Dust storms roll through the Tri-Cities regularly, and fine particulates enter homes through every gap the wind can find. Homeowners in Pasco and Kennewick who have had air sealing done consistently report that their homes feel cleaner and require less frequent dusting - a benefit that does not show up on the utility bill but matters to families every single day.
Pacific Power serves much of the Kennewick area and offers rebates for qualifying air sealing work through its energy efficiency programs. The Building Performance Institute sets the diagnostic and installation standards we follow - the same standards that Pacific Power requires for rebate-eligible work.
We respond within 1 business day. Let us know your home's age, any comfort complaints you have noticed, and whether you have had prior weatherization work done. No obligation, no pressure.
We set up a blower door test - a large fan in your front door that depressurizes the house - to find exactly where air is leaking in and how severe the problem is. The assessment takes one to two hours and gives you a clear picture before any work begins.
You receive a written estimate that specifies what will be sealed, where, and at what cost. We also walk you through Pacific Power rebate eligibility and any applicable federal tax credits at this stage - not after the invoice.
The crew seals gaps with foam, caulk, or rigid barriers and runs a second blower door test when done. You see the before-and-after numbers in plain terms - proof the job made a real difference, not just a verbal assurance.
Blower door test included with every assessment. Written estimate before work begins. No obligation to move forward.
(509) 206-9343We measure air leakage before we start and again when we finish, then share both numbers with you. That is the only objective way to confirm the work actually improved your home - and it is something many contractors skip entirely.
Sustained winds of 15 to 25 mph are common in Kennewick, and gusts regularly exceed 40 mph. We seal to a standard that holds up under that pressure - not the minimum that passes a mild-climate test. Homes here need tighter work than calmer parts of Washington.
We have worked in homes across Kennewick and the surrounding region. We know which parts of the housing stock have the worst attic bypasses, the most exposed rim joists, and the highest air leakage rates - and we know how to fix them efficiently.
Our contractor registration is current and verifiable through the Washington State Department of Labor and Industries. When a permit is required for your project, we pull it - we do not skip that step to save time at your expense.
Every air sealing job we complete in Kennewick is backed by measured results and a licensed contractor who stands behind the work. If the numbers do not improve, we have not done our job - and we will not leave until they do.
Basement rim joists are among the leakiest spots in older Kennewick homes - air sealing and basement insulation are typically done together as part of the same project.
