Hot, humid air sneaks into Kailua homes through gaps you cannot see - around pipes, outlets, and the attic floor above you. We find every leak, seal it, and prove the improvement with before-and-after testing.
Air sealing in Kailua means finding every gap, crack, and opening where hot outside air sneaks in - and closing those openings with foam, caulk, or weatherstripping - most jobs are completed in one to two days with measurable before-and-after results.
The biggest leaks are rarely the obvious ones around doors and windows. In Kailua homes - especially those built before 1980 - the worst culprits are usually hidden: where pipes or wires pass through walls, around recessed lights in the ceiling, along the edges where walls meet the attic floor above you, and around electrical outlets on exterior walls. The tradewinds that feel pleasant outside can drive warm, moist air through these tiny gaps all day long.
Air sealing works best when combined with attic air sealing - addressing the attic floor boundary is often the highest-impact area in a Kailua home because hot air collects in vented attics and radiates down unless the floor is properly sealed. For homes that also need upgraded thermal barriers, basement insulation can address heat entering from below in homes with raised foundations.
If your Hawaiian Electric bill has been creeping up month after month and you have not added new appliances or changed how you use your AC, air leaks are a likely culprit. In Kailua's climate your cooling system runs almost constantly, and even small gaps can force it to work significantly harder. A noticeable increase during the hotter summer months is one of the clearest signs conditioned air is escaping.
If one bedroom or the back of the house always feels hotter than the front - even with the AC running - that is often a sign that hot outside air is getting in through nearby gaps. In Kailua homes with vented attics, rooms directly below the attic floor are especially prone to this. You should not have to close off a room just to make it livable.
Kailua's humidity is high year-round, and when warm, moist outside air leaks into a cooled home it can condense on cool surfaces and create conditions for mold or mildew. If you notice a persistent musty odor or small dark spots near ceiling edges, air leaks may be allowing humid air to enter faster than your home can manage it. This is worth addressing quickly, because moisture problems get worse over time.
Hold your hand near an electrical outlet on an exterior wall, or near a recessed light in your ceiling. If you feel a faint movement of air - especially on a windy day when the tradewinds are strong - that is outside air coming through gaps in the wall or ceiling. These spots are easy to overlook but are among the most common sources of air leakage in older Kailua homes.
We begin every air sealing job with a blower door test - a large fan placed in your doorway that depressurizes the house and makes air leaks measurable and often physically noticeable. This gives us a documented baseline before any materials are applied, so when we run the test again after sealing you can see the improvement in real numbers. We use spray foam for larger gaps and hard-to-reach areas, and caulk or weatherstripping for smaller cracks around windows and doors.
For homes where the attic floor is the main problem area, we coordinate attic air sealing as part of the same job - addressing both the attic boundary and wall penetrations in one visit. For homes that need additional thermal protection underneath, basement insulation handles the raised-foundation gap that air sealing alone cannot solve.
Best for homeowners who want proof - we measure leakage before and after, giving you documented numbers showing exactly how much the job improved your home.
Best for Kailua homes with vented attics - sealing the boundary between your living space and the hot attic above is often the single highest-impact area to address.
Best for older homes where plumbing, electrical wiring, and decades of settling have opened gaps through walls and ceilings that let outside air pour in.
We provide the before-and-after blower door results and a written summary of the work done - everything you need to apply for Hawaiian Electric rebates and federal tax credits.
Hawaii consistently has the highest residential electricity rates in the country - often two to three times the national average. That means every dollar saved on cooling has more impact here than it would on the mainland. Air sealing projects that might take eight to ten years to pay back in a cooler, cheaper-energy state can pay back much faster in Kailua, where your cooling system runs nearly year-round. Kailua also sits on the windward side of Oahu, where the tradewinds that make the town feel pleasant outdoors also drive warm, moist air through every unintended gap in your home's shell.
We serve homeowners throughout the area, including Kahaluu and Heeia. Homes in these windward communities share the same challenges as Kailua - older post-war construction, salt air that degrades existing seals faster than on the mainland, and AC systems working overtime against a leaky envelope. Kailua's salt air environment also means that exterior seals around windows and doors degrade faster here than they would in a drier climate, so air sealing is worth revisiting every several years.
We respond within one business day. We will ask a few questions - your home's size, when it was built, and what has been prompting your concern - so we come prepared with the right equipment and a realistic estimate of how long the job will take.
We place a large fan in your front doorway to depressurize the house, making air leaks measurable and often physically noticeable. The assessment takes one to two hours, and you can see the results before any work begins. There is no pressure to commit on the spot.
Most jobs take one to two days. We work through the identified areas - attic floor, plumbing and electrical penetrations, wall and ceiling edges - applying foam or caulk to close each gap. You can usually stay in your home, though you may need to stay out of specific rooms for a few hours while foam cures.
We run the blower door test again after completing the work and show you the before-and-after comparison in plain numbers. We also provide a written summary of what was sealed - which you will need to apply for Hawaiian Electric rebates or the federal energy efficiency tax credit.
We test before and after - you see the improvement in real numbers. Free estimate, no commitment.
(808) 556-0595Any contractor can apply foam and leave. We run a blower door test at the start and again at the end, so you have documented proof that the work made a measurable difference. In Kailua, where you are paying some of the highest electricity rates in the country, you deserve to see that in real numbers.
We work throughout Kailua and the surrounding windward communities. We know what to expect in homes built in the 1950s through 1970s - the concrete block walls, the original plumbing penetrations, and the spots that decades of settling and salt air exposure have opened up. We come prepared, not surprised.
Hawaiian Electric rebates and the federal tax credit for air sealing require specific before-and-after documentation. We provide a complete written summary before we leave the job site, so you can submit your rebate application without having to chase down records after the fact.
A well-sealed home needs intentional ventilation management - especially in Kailua's humid climate. We make sure your existing exhaust fans are adequate for the level of sealing we complete, and we discuss any ventilation considerations with you before we finish the job. Learn more from the Building Performance Institute.
With Kailua's electricity rates and the windward coast's persistent heat and humidity, air sealing is one of the fastest-payback improvements you can make to an older home. We bring the testing, the experience, and the documentation process to make sure you get the full benefit.
Target the attic floor boundary specifically - the single highest-impact area for reducing heat gain in most Kailua homes with vented attics.
