Gaps and cracks you cannot see are draining your energy budget every day. We find them, seal them, and verify the results so you know the work was done right.
Air sealing services in Duncan, OK, mean closing the gaps and cracks in your home where outside air sneaks in and conditioned air leaks out - a process that reduces energy waste and improves comfort, with most whole-home jobs completed in one to two days.
Most of the worst air leaks in a home are invisible. They hide in attic floors, around recessed light fixtures, where pipes and wires pass through framing, and along the joint where your walls meet the attic. You cannot see them, but you pay for them every month on your energy bill. In Duncan, where older housing stock is the norm and Oklahoma's wind pushes outside air through gaps with real force, those leaks are costing more than most homeowners realize.
Air sealing works best when it is paired with insulation upgrades. Combining this service with basement insulation or attic air sealing addresses the envelope from multiple angles and compounds the savings.
If your electric bill climbs dramatically from May through September even though you have not changed your habits, your home is likely losing conditioned air faster than your system can replace it. In Duncan, where summer heat is intense and prolonged, a leaky home forces your air conditioner to run almost constantly - and you pay for every extra minute.
If one room always feels stuffy in summer or cold in winter regardless of what the thermostat says, that room likely has air leaks nearby - often in the ceiling, around an electrical outlet on an exterior wall, or near a window frame. In older Duncan homes, these problem rooms are common because original construction left gaps that were never sealed.
Hold your hand near a recessed light fixture in your ceiling on a windy day. If you feel air movement, that fixture is connected to your attic, which is connected to the outside. Attic hatches that are not insulated or sealed are another major culprit. These are among the biggest air leak sources in Oklahoma homes.
If you have lived in your home for years and no contractor has ever assessed where it loses air, there is a very good chance you have significant leaks. This is especially true for Duncan homes built before the 1980s. A proactive assessment can find problems before they cost you another full season of high bills.
A thorough air sealing project starts with a blower door test - a temporary fan mounted in a doorway depressurizes the house and reveals exactly where air is moving in. That test takes the guesswork out of the job. Instead of spraying foam in obvious spots, we know precisely where your home is losing air before we touch a single surface. Results from a second test after the work confirm that the house is measurably tighter than before we arrived. That verification is something you can keep.
The physical sealing work covers attic floors, top plates, around all penetrations, crawl space rim joists, and anywhere the assessment identifies leakage. This work connects naturally with basement insulation when the lower envelope needs attention, and with attic air sealing when the attic floor is the primary source of leakage. Each upgrade compounds the benefit of the others.
Best for homeowners who want a comprehensive assessment and sealing of every major leak source in one project.
Best for homes where the attic-to-living-space boundary is the primary source of heat gain and air loss.
Best for pier-and-beam or raised-foundation homes where cold or hot air enters from below the living floor.
Best for newer homes or recent renovations where specific problem areas have been identified by an energy audit.
Duncan sits in south-central Oklahoma, where summer temperatures regularly climb above 100 degrees and winter cold snaps can arrive within the same season. That kind of range puts enormous pressure on your HVAC system - and every gap in your home's shell makes it work harder. Oklahoma consistently ranks among the windiest states in the country, and wind pressure pushes outside air through gaps more aggressively than in calmer climates. Homeowners in Duncan often feel drafts that seem out of proportion to the size of the gap, and that is exactly why air sealing delivers noticeable comfort improvements here faster than in many other parts of the country. Customers in Lawton, OK and Chickasha, OK face the same wind-driven leakage problems, and we serve the full region.
A large share of Duncan's housing was built during the mid-20th century oil boom era, before modern energy codes existed. Many of those homes were never designed with air tightness in mind, which means they have significant gaps that have never been addressed. Sealing those gaps is one of the most direct ways to bring an older Duncan home closer to modern performance standards without a full renovation. ENERGY STAR's Seal and Insulate guidance identifies air sealing as the first step before adding insulation - and that order matters.
Contact us by phone or through the contact form and we will follow up within one business day. We will ask about your home's age and any comfort problems you have noticed to come prepared for the assessment.
We mount a temporary fan in a doorway, depressurize the home, and locate exactly where air is moving in. This test takes about an hour and gives us a precise map of your problem areas before any work begins.
After the assessment you receive a written estimate broken down by area - attic, crawl space, living space penetrations - so you understand exactly what you are paying for. This is also the right time to ask about utility rebates and federal tax credits.
The crew moves systematically through every area identified in the assessment, applying foam, caulk, or weatherstripping as needed. A second blower door test after the work confirms your home is measurably tighter - we share those results before we leave.
Free assessment. Verified results. No pressure to commit.
(580) 860-0708We run a blower door test before and after every whole-home project. That means you receive actual numbers showing how much tighter your home is - not just a verbal promise. That documentation is yours to keep.
Our license from the Building Performance Institute-aligned approach and Oklahoma Construction Industries Board licensing means we have met the state's requirements and carry the coverage that protects your home if anything goes wrong.
Most of our air sealing work is on pre-1980 homes where original construction left gaps that have never been addressed. We know where to look in the housing types that make up most of Duncan's neighborhoods - from downtown wood-frame homes to mid-century brick ranches across Stephens County.
Oklahoma Gas and Electric and Oklahoma Natural Gas both offer energy efficiency programs, and federal tax credits are available for qualifying air sealing work. We walk every customer through what applies to their project so no savings are left on the table.
Choosing an air sealing contractor in a smaller market like Duncan means asking the right questions up front. We welcome all of them - license number, insurance, test results, references - because a contractor confident in their work has nothing to hide.
