Serving Duncan, OK and surrounding areas. (580) 860-0708
Cold floors and climbing energy bills often start beneath your home. We insulate and seal your crawl space so Oklahoma weather stays where it belongs - outside.
Crawl space insulation in Duncan creates a thermal barrier between the cold or hot ground beneath your home and the living spaces above it. Without it, outdoor temperatures travel straight through your floors. Most jobs take one to two days, and you do not need to leave your home during the work.
In Duncan and across Stephens County, a significant share of homes were built in the 1950s through 1980s with vented crawl spaces - a design that was standard at the time but that lets in humidity, insects, and outside air. After 30 or more years, the original insulation in those spaces has almost certainly compressed, sagged, or been disturbed by plumbing and pest control work. The result is floors that feel cold in January and a heating system that runs longer than it should.
If you are also dealing with moisture issues at the ground level, a crawl space vapor barrier is often installed at the same time. For homes with insulation in other areas that also needs attention, our wall insulation service rounds out the full building envelope.
If you walk across your kitchen or living room on a January morning and the floor feels noticeably cold through your socks, that is a classic sign that little or no insulation is working beneath you. Duncan winters bring hard freezes, and an uninsulated crawl space lets that cold air sit right under your feet.
If your heating or cooling costs have risen over the past few years and nothing changed in your habits, degraded crawl space insulation is a likely culprit. Oklahoma's extreme temperature swings put a heavy load on HVAC systems, and when insulation fails, your system has to run longer to compensate.
A persistent musty or earthy odor - especially in rooms near the floor - often points to moisture problems in the crawl space below. Duncan's clay soils hold water, and when that moisture has nowhere to go, it creates the damp conditions that produce that smell. Left alone, it can lead to mold growth and wood rot.
If you have ever peeked into your crawl space and seen insulation hanging down, bunched up, or missing in patches, it is no longer working. Insulation that has fallen away from the floor joists above it is essentially useless - air moves freely around it. This is especially common in older Duncan homes where the original insulation was never replaced.
We offer two main approaches to crawl space insulation. The first is floor joist insulation - installing batts or spray foam against the floor joists above the crawl space to create a thermal boundary at the base of your living area. The second is full encapsulation - sealing the walls, floor, and any vents of the crawl space itself to turn it into a conditioned space that moisture and pests cannot enter. Both approaches work; encapsulation tends to be more thorough because it blocks moisture entry at the ground level, not just at the floor above.
Moisture control is part of the job, not a separate project. We check for standing water, condensation, and ground moisture before installing anything, because insulation installed over a wet crawl space will fail quickly. A crawl space vapor barrier is often included. We also check any ductwork running through the space - a common source of energy loss in Duncan homes that gas heat systems. If the existing material needs to come out first, our wall insulation team can coordinate the full scope in one visit.
Best for homes where the primary goal is stopping heat loss through the floor - straightforward, effective, and compatible with vented crawl spaces.
Best for homes with persistent moisture, musty odors, or a history of pest activity - seals the entire crawl space environment, not just the floor above.
Best as a standalone improvement or paired with floor joist insulation - stops ground moisture from evaporating into the crawl space and reaching your wood structure.
Best for homes where the original insulation has been in place for decades - old material comes out, the space is inspected, and new insulation goes in clean.
The soils in Stephens County contain a high percentage of clay. Clay soils hold moisture and push it upward toward your home's foundation and crawl space floor. This is a major reason why vapor barriers are essential here, not optional - without one, moisture wicks up from the soil and can rot wood, grow mold, and destroy insulation from below. Duncan summers push above 100 degrees and winters drop well below freezing, meaning the crawl space insulation has to work hard in both directions year-round.
Oklahoma's severe weather season runs roughly from March through June, and Duncan is well within the region that sees frequent high-wind events. After a major storm, it is worth checking your crawl space - water intrusion and debris can damage insulation that was previously fine. Homeowners in Duncan and the surrounding area of Comanche often find crawl space insulation problems after a rough spring. The U.S. Department of Energy recommends crawl space insulation as one of the highest-value weatherization investments for homes in climates with both hot summers and cold winters.
We ask a few questions - your address, approximate home size, and the symptoms you have noticed. We respond to new requests within one business day and schedule the estimate visit at a time that works for you. No obligation.
A contractor accesses your crawl space - usually through an exterior hatch or an interior access panel - and spends 20 to 45 minutes checking insulation condition, moisture levels, the vapor barrier if one exists, and the size of the space. You get a written estimate with a clear breakdown of what is being done and what it costs.
The crew handles everything: old insulation removal if needed, vapor barrier installation, and new insulation. Most jobs finish in one day. You do not need to leave your home - the crew works in the crawl space and cleans up before leaving.
Before leaving, we walk you through what was done and show you photos taken inside the crawl space so you can see the work without having to go in yourself. We also tell you what to watch for - signs of moisture returning, or areas to check after heavy rain.

(580) 860-0708We assess moisture conditions before touching the insulation. Installing over a wet crawl space is one of the most common contractor mistakes in this climate - it traps the problem and causes the new insulation to fail within a few years. We do not skip this step.
Oklahoma requires insulation contractors to be licensed through the Construction Industries Board. You can verify our license status on the CIB website before scheduling. That license also means we carry the insurance that protects you if anything unexpected happens on the job.
A significant share of homes in Duncan were built in the 1950s through 1980s with original crawl space designs that were never updated. We know what to expect in these homes - including the non-standard access points, older vapor barriers, and insulation types common in this part of Stephens County.
You should not have to take a contractor's word for what they did in a space you cannot easily see. We photograph the crawl space before and after the job so you have a clear record of what was installed and the condition of the space when we left.
Crawl space work in Oklahoma is not a one-size-fits-all job. The clay soil conditions, the age of the housing stock, and the severity of the climate here mean that what works in another part of the country does not always apply. We work on homes in Duncan and Stephens County specifically - that local knowledge matters on every job.
