Serving Duncan, OK and surrounding areas. (580) 860-0708
Hot attic air sneaks into your home through dozens of small gaps. We find them all, seal them tight, and give your AC a fighting chance against Oklahoma summers.
Attic air sealing in Duncan means finding and closing every gap in your attic floor - around light fixtures, plumbing pipes, wall top plates, and the attic hatch - so conditioned air stays inside and outside air stays out. Most jobs are completed in a single day with no disruption to your household.
If your home was built before the mid-1980s, it was almost certainly never professionally sealed. Those gaps let hot attic air pour into your living space all summer, forcing your AC to run harder and longer to keep up. Paired with retrofit insulation, air sealing is the most effective comfort upgrade most Duncan homeowners can make.
The good news is that the work is straightforward. A technician works entirely in the attic - your furniture, your schedule, and your daily routine stay untouched. And once it is done right, the results last for decades.
If rooms directly below your attic feel much hotter than the rest of the house during Duncan summers, hot attic air is pushing through gaps in the ceiling. Your AC is fighting it constantly, which shows up on your OG&E bill. This is one of the clearest signs that sealing work is overdue.
If your cooling costs keep rising without a clear reason, air leaks are one of the most common culprits. Duncan homes sit on clay soils that shift with the seasons, quietly opening new gaps even in houses that were in good shape when you moved in. A steady creep in your summer bill is worth investigating.
Hold your hand near a recessed light or the edges of your attic hatch on a hot day. If you feel warm air moving downward, you have an air leak right there. Recessed lights and attic hatches are among the most common entry points in Oklahoma homes, and they are also among the easiest to seal properly.
Surfaces that seem to get dusty within days of cleaning often have outside air - carrying red clay dust and pollen - being pulled in through attic gaps. Duncan wind drives that air through any opening it can find. If your home feels perpetually dusty, air infiltration from above is worth ruling out before you blame anything else.
Every attic air sealing job starts with a full inspection of the attic floor. We move insulation aside, find every penetration - pipes, wires, light canisters, wall top plates, chimneys - and seal each one with caulk or foam rated for the application. Nothing gets skipped because hidden gaps are just as costly as visible ones. We also address whole-home air sealing when a broader approach makes sense for the home.
For homes that have never been evaluated, we pair sealing work with an assessment of the existing insulation. If what is there is thin, settled, or damaged, we will tell you - and we can handle both jobs at once. Adding insulation on top of unsealed gaps is the most common mistake in this industry, and it is one we do not make. Whether you need sealing only or a combined project with retrofit insulation, we lay out exactly what is there and what it will take to fix it before any work begins.
Best for homes where gaps around plumbing, wiring, and light fixtures are the main source of air leakage - the most common situation in Duncan homes built before 1990.
For homeowners whose attic hatch or pull-down stair is a primary leak point - a quick but high-impact fix that makes a noticeable difference right away.
Ideal for older Duncan homes where insulation is thin and gaps are numerous - we seal first, then top off the insulation in the same visit so you get the full benefit of both improvements.
For homeowners who want a measurable result - we run a before-and-after air leakage test so you have a real number showing the improvement, not just a contractor's assurance.
Duncan sits in south-central Oklahoma where summer temperatures regularly exceed 100 degrees and the cooling season stretches from late April through October. That means your air conditioner is fighting extreme heat for more than half the year. Every gap in your attic floor makes that fight harder. Homeowners here tend to see a faster payback on air sealing than people in milder climates because the energy savings add up across such a long season. On top of the heat, Oklahoma wind creates pressure differences across your home that actively push outside air through any gap it can find - so leaks here are not just passive, they are being driven in by wind pressure.
A significant portion of Duncan homes were built between the 1940s and 1980s, an era when builders paid no attention to air sealing. Many of those homes have also spent decades sitting on clay-heavy soils that expand and contract with Oklahoma rainfall - movement that quietly opens new gaps around wall top plates, chimneys, and penetrations even in homes that were sealed at some point in the past. Homeowners across Marlow and Comanche face the same combination of older housing stock and expansive soils. If your home is more than 15 years old and has never been evaluated, having the attic checked is a reasonable next step.
We will ask a few basic questions - your home's age, size, and any comfort problems you have noticed. We respond within one business day and get you scheduled for an in-home assessment, which is a separate visit from the actual work day.
A technician inspects the attic floor, identifies gaps, and explains what was found in plain language. You receive a written estimate covering exactly what we will do and what it costs. No pressure, no upselling - just a clear picture.
The crew works entirely in the attic, moving insulation aside and sealing each penetration with caulk or foam. Most standard homes are finished in four to eight hours. You stay home, your furniture stays put, and your day continues normally.
Before we leave, we walk you through what was done and provide any paperwork you need for an OG&E rebate or federal tax credit. You will know exactly what was sealed and what to expect in the months ahead.
Free estimate. No pressure. We reply within one business day.
(580) 860-0708Adding insulation over unsealed gaps is the most common mistake in this trade - it makes the insulation look better on paper while leaving the root problem untouched. We seal every gap first. That is the step that makes everything else work, and it is non-negotiable on our jobs.
Oklahoma requires insulation contractors to be licensed through the Oklahoma Construction Industries Board. We hold that license, carry the required insurance, and you can verify our status directly on the CIB website before you sign anything.
We know what Oklahoma Gas and Electric requires for rebate documentation and we handle that paperwork as part of the job. Most contractors do not - which means their customers leave money on the table. We make sure you do not. The federal tax credit paperwork is handled the same way.
We photograph the attic before and during the work so you can see what was there and what we did about it. You should never have to take a contractor's word that the job was done right. The photos, the walkthrough, and the written scope of work give you real accountability - not a promise.
Every one of these proof points comes back to the same thing: we do the job right and we show our work. If you want to understand why Duncan homeowners keep calling us back, that is the short answer.
Add insulation to walls, attics, and crawl spaces in your existing Duncan home without tearing anything apart.
