Most Lawton homes lose a quarter or more of their heating and cooling through gaps and cracks. We find every one, seal it, and prove the difference with a blower door test.
Most Lawton homes lose a quarter or more of their heating and cooling through gaps and cracks. We find every one, seal it, and prove the difference with a blower door test.
Air sealing in Lawton means finding and plugging every gap, crack, and opening in your home's shell - around pipes, wires, light fixtures, attic hatches, and wall joints - so outside air stops sneaking in and conditioned air stops leaking out. Most jobs take one to two days for a typical home, and the results are verified with a diagnostic blower door test before and after the work.
Air sealing is not the same as insulation. Insulation slows heat transfer through a surface. Air sealing stops the movement of air through gaps entirely. The two work best together, which is why we often pair air sealing with basement insulation or attic work in the same visit. In Lawton's wind-driven climate, a home that has been insulated but not air-sealed is still losing energy every time the south wind picks up - because wind pressure pushes outside air through every small gap with real force. Addressing both problems together is the only way to fully stop the cycle.
If your cooling bills jump dramatically during the hottest weeks of summer - even when you have not changed your habits - that is a strong sign your home is letting in outside air through gaps and cracks. Lawton's summer temperatures regularly exceed 100 degrees, and an air-leaky home forces your air conditioner to run almost constantly just to keep up.
Hold your hand near an electrical outlet on an exterior wall on a windy day. If you feel air moving, that outlet is connected to a gap in your wall cavity that goes straight to the outside. Lawton's persistent winds make this easy to test - the pressure difference between inside and outside is often strong enough to feel clearly.
When some rooms are comfortable and others never quite get there, it usually means air is moving unevenly through the house. Hot attic air leaking into upstairs rooms in summer, or cold air seeping in through a crawl space in winter, creates those temperature differences. This is especially common in Lawton's older neighborhoods.
Bugs, dust, and outdoor odors all enter your home through the same gaps that let air in. If you are finding more insects than usual near light fixtures or baseboards, or if a room smells musty without an obvious moisture source, those are entry points that also leak conditioned air every day.
We start every air sealing job with a blower door test - a diagnostic fan mounted in your front door that depressurizes the house and makes hidden leaks much easier to detect. That test gives us a clear picture of how much air is escaping and where the biggest opportunities are. From there, we work through your attic, crawl space or basement, and any accessible wall penetrations, applying two-component spray foam, acoustic caulk, or weatherstripping depending on the size and location of each gap. Many jobs also benefit from attic air sealing specifically, where the top plates of interior walls and the spaces around recessed lights and plumbing penetrations are sealed from above before any insulation is added on top.
When the work is done, we run the blower door test again and share both numbers with you. The difference tells the story - no need to take our word for it. We also review whether your home needs any ventilation upgrades, since a more airtight home needs controlled fresh air rather than random cracks. Air sealing pairs naturally with basement insulation and wall insulation to create a complete, continuous thermal envelope.
Before-and-after pressure testing that quantifies air leakage and confirms the work made a measurable difference.
Foam and caulk applied to the most leak-prone area in most homes - around pipes, wires, light fixtures, and framing joints in the attic floor.
Gap sealing at floor-to-wall joints, utility penetrations, and rim joists where cold air and moisture commonly enter.
Foam applied to outlet boxes, pipe chases, and any accessible wall penetration that connects your living space to the outside.
Lawton sits in a climate zone that swings from triple-digit summer heat to hard freezes in winter, sometimes within the same month. That kind of thermal stress causes building materials to expand and contract repeatedly, which opens up gaps and cracks over time - even in relatively newer homes. Oklahoma is also one of the windiest regions in the country, and Lawton's persistent south winds push outside air through even small gaps with real force. Wind-driven infiltration is different from passive air leakage - the pressure differential is constantly changing, which means your HVAC system is fighting an uneven battle on every breezy day. Homeowners in Duncan and Chickasha deal with the same wind-driven infiltration and benefit from the same approach.
Lawton's soils add another layer to this problem. The clay-heavy ground across much of Comanche County expands when wet and shrinks during dry spells - and that seasonal movement shifts your home's framing just enough to open new gaps at the base of walls and around utility penetrations over time. Many Lawton homeowners also never had their homes air sealed when they were built, particularly in neighborhoods that went up around Fort Sill in the 1950s through 1970s, when the concept simply was not part of residential construction. Oklahoma also participates in the federal Weatherization Assistance Program, which provides free or low-cost air sealing to income-qualifying households - ask us about eligibility when you call. More information is available at the U.S. Department of Energy.
We ask about your home's age, size, and what prompted you to call. We reply within one business day and most assessments are scheduled within the week. No pressure, no commitment required.
We walk your home and run a blower door test - a diagnostic fan that reveals where air is leaking. We check the attic, crawl space or basement, and main living areas. This typically takes two to three hours.
After the assessment you receive a written estimate that covers what was found, what we recommend sealing first, and the total cost. Ask anything before signing - a straightforward answer is the only kind we give.
We work through the attic, crawl space, and penetrations applying foam and caulk. When finished we run a second blower door test and share both numbers so you can see exactly how much air leakage was reduced.
Free estimate, no obligation. We reply within one business day.
(580) 350-5041We run a diagnostic test before we start and again when we finish, so you have actual air leakage readings from both sides of the job. Those numbers are yours to keep - not just our word that the work made a difference.
Lawton's shrink-swell clay soils have been shifting homes in this area for decades, opening new gaps at wall bases and utility penetrations that most contractors overlook. We specifically inspect those lower areas - not just the attic - on every Lawton job.
We serve homeowners in Lawton, Duncan, Anadarko, Altus, and eight more communities throughout southwest Oklahoma. Local crews who know this climate, these soils, and the aging housing stock that makes air sealing a real priority here.
The federal Energy Efficient Home Improvement Credit can cover up to 30% of qualifying air sealing project costs. We tell you upfront whether your project qualifies so you can take advantage of it at tax time. Certification standards for this work are set by programs like ENERGY STAR.
Air sealing is one of the highest-return improvements you can make to a Lawton home - and the before-and-after blower door test is the clearest proof in the industry that the work was done right. We show you the numbers, explain what they mean, and let the results speak for themselves.
Insulate the walls and rim joists of your basement or foundation to stop cold air from rising into your living space.
