Duncan homes lose cooled air through dozens of small gaps that traditional insulation never touches. Open-cell foam expands into every crack and seals your home from the inside out.

Open-cell foam insulation in Duncan, OK, seals air leaks and slows heat transfer in a single step, and most residential jobs covering an attic or crawl space are completed in one day.
The problem most Duncan homeowners face is not missing insulation - it is the dozens of small gaps around wires, pipes, and framing that let conditioned air escape and outside heat push in. Traditional batts slow heat, but they do not seal those gaps. Open-cell foam expands on contact, filling every void and creating a continuous barrier that standard insulation cannot match.
For homes that need an airtight envelope, open-cell foam pairs naturally with commercial insulation upgrades for larger buildings, or with closed-cell foam insulation in areas where moisture resistance is the priority.
If your electric bill climbs dramatically from June through August and your habits have not changed, your home is likely losing a significant amount of cooled air through gaps. In Duncan's climate, a home that is not well sealed works your air conditioner harder than it should have to, and you feel it in your wallet every month.
If one bedroom, a bonus room over the garage, or a room at the end of a hallway always feels warmer in summer no matter how long the AC runs, that room likely has an insulation or air-sealing problem. This is especially common in older Duncan homes where insulation was installed unevenly or has settled over the years.
Hold your hand near an electrical outlet on an exterior wall on a windy day. If you feel air moving, outside air is getting in through gaps in your wall cavity. Duncan's persistent winds make this problem worse than in calmer parts of the country, and it means your insulation - whatever is there - is not doing the job on its own.
Go into your attic on a summer afternoon and pay attention to how hot it is. If it feels unbearable and the ceiling below feels noticeably warm, heat is radiating down into your living space. In south-central Oklahoma's summers, an uninsulated or under-insulated attic can reach temperatures that overwhelm even a well-functioning air conditioner.
We install open-cell foam in attics, crawl spaces, interior walls, and the underside of roof decking - wherever air leakage is costing you comfort and money. For attic applications, foam is sprayed directly onto the underside of the roof deck, creating an unvented assembly that keeps conditioned air from escaping through the ceiling plane. For homeowners who want a complete envelope upgrade, this service pairs naturally with closed-cell foam insulation in areas that need vapor resistance as well as air sealing.
For larger or more complex projects - commercial buildings, warehouses, or multi-unit spaces - we also offer commercial insulation services tailored to the different construction types common in Stephens County. We assess the space first and recommend the right product and thickness for your specific application before any work begins.

Best for homes where air leakage from below the floor is driving energy costs and moisture concerns.
Best for renovation projects or new construction where wall framing is accessible for full coverage.

Duncan sits in south-central Oklahoma where summer temperatures regularly climb into the mid-to-upper 90s and the heat index can push well past 100 degrees. Homes without good air sealing and insulation force air conditioners to run almost constantly from May through September. A significant portion of Duncan's housing was built in the 1950s through the 1980s, when insulation standards were far less demanding than they are today - many of those homes have little or no insulation in the walls, and whatever is in the attic has likely settled or degraded over decades. For homeowners in these older neighborhoods, open-cell foam is often the first real air seal the house has ever had, and the difference in comfort is usually immediate. Homeowners across the region in Marlow, OK and Chickasha, OK face the same conditions, and we work throughout the area.
Oklahoma is also one of the windiest states in the country, and Duncan is no exception - the area regularly sees sustained winds and gusts that push outside air through every small gap in a home's envelope. Traditional insulation slows heat movement but does almost nothing to stop wind-driven air infiltration. Open-cell foam seals those pathways, which is why homeowners in windy south-central Oklahoma often see a more dramatic improvement than homeowners in calmer climates. The ENERGY STAR Seal and Insulate program recognizes air sealing combined with insulation as the most effective home energy upgrade available.
Reach out by phone or through the contact form and we will respond within one business day. We will ask a few basic questions about your home's age and the areas you want covered so we come prepared.
We walk through the areas you want insulated - attic, crawl space, walls, or all of the above. We measure the space, assess what is already there, and talk through what we recommend. No cost, no obligation.
You receive a written estimate that states what areas will be covered, how thick the foam will be applied, and the total cost. No surprises on installation day and no verbal-only quotes.
The crew arrives, suits up, and sprays the foam in the areas outlined in your estimate. Most jobs finish in one day. Before leaving, we give you a specific re-entry time - typically 24 hours - and a final walkthrough of the finished work.

(580) 860-0708We have been installing insulation in Duncan and the surrounding communities since 2016. That time in the local market means we know the housing stock, the climate challenges, and the specific issues older south-central Oklahoma homes present. That knowledge shapes every estimate and every installation.
We hold a current license through the Oklahoma Construction Industries Board, the state body that oversees insulation contractors. You can verify any contractor's license on the CIB's public lookup tool before signing anything. We also carry full liability and workers' compensation coverage on every job.
One of the biggest fears homeowners have is not knowing whether the work was actually done right. With open-cell foam, the finished product is visible before any drywall goes up. We walk you through the finished work and answer your questions - you can see the coverage, the thickness, and every area that was treated.
Every job starts with a written estimate that spells out what will be done, where, and at what cost. We do not give verbal quotes over the phone without seeing the space, and we do not start work until you have approved the written scope. You know what you are paying for before anyone picks up a spray gun.
You can check any Oklahoma insulation contractor's license status through the Oklahoma Construction Industries Board. We encourage every homeowner to do exactly that - for us and for any contractor they consider.
