Stillwater Insulation is a licensed insulation contractor serving Norman, OK with home insulation, spray foam, and attic insulation services. We have served Cleveland County homeowners since 2025 and respond to every inquiry within 1 business day.

A large share of Norman homes were built in the 1960s through 1980s, when insulation standards were a fraction of what they are today. Our home insulation service covers attics, walls, floors, and crawl spaces so every part of the building envelope is addressed, not just the easiest access point.
Norman attics see brutal heat every summer - attic temperatures can exceed 150 degrees on a July afternoon, and thin or compressed insulation lets that heat press straight into your living space. Adding blown-in insulation to the attic is the single fastest way to reduce summer cooling bills in a Norman home.
Spray foam is especially useful in Norman homes near the University of Oklahoma campus, where older construction often has gaps around wiring, plumbing, and framing that no amount of batt insulation can seal. It air-seals and insulates in one pass, which makes a real difference in homes with drafty floors and fluctuating room temperatures.
Norman sits on the Canadian River plain, and the clay-heavy soil here holds moisture and releases it upward into crawl spaces. Properly insulating and conditioning the crawl space breaks that moisture cycle, protects floor joists from long-term damage, and keeps floors noticeably warmer in winter.
Norman homes from the 1950s and 1960s were not built with air tightness in mind. Sealing gaps around top plates, light fixtures, plumbing penetrations, and attic hatches before adding insulation is what separates a thorough job from one that just piles more material on top of a leaky shell.
Blown-in cellulose or fiberglass is a natural fit for Norman rental properties and owner-occupied homes alike - it adds coverage quickly without tearing out walls, fills around irregular framing and wiring, and is particularly effective for topping up attics that have original batts that have thinned over decades.
Norman sits in Cleveland County on the Canadian River plain, where the soil is predominantly clay. That soil expands when it absorbs rain and shrinks when it dries out - a cycle that runs every year without fail. The constant movement puts stress on slab foundations and pushes moisture toward crawl spaces and lower wall assemblies. Standard fiberglass batts sitting on a crawl space floor do nothing to slow that moisture, and many Norman homes have been relying on exactly that setup for 40 or 50 years.
The climate piles on from every direction. Norman summers push past 95 degrees regularly, and the heat index adds more. Norman winters bring ice storms - the area is one of the most ice-storm-prone regions in the United States, and freeze-thaw cycles run from December through February. The bulk of Norman housing stock was built between the 1950s and 1990s, when Oklahoma building codes required insulation levels that are well below current recommendations. Homes that have never been upgraded are losing money through the attic and walls every season, and a contractor who has not worked extensively in this area may not recognize which problems are structural versus which are simply underinsulation.
Stillwater Insulation has served Cleveland County homeowners since 2025, and we pull permits through the City of Norman Building Safety Division when the scope of work requires one. We work regularly on the full range of Norman housing - from the small brick ranch homes and craftsman bungalows near the University of Oklahoma campus to the larger slab-foundation houses in the newer subdivisions on the south side of town near 24th Avenue SW.
Norman is roughly 20 miles south of Oklahoma City along Interstate 35, and the city has grown steadily as the metro has expanded. The University of Oklahoma is the defining institution here, and it shapes the housing market in ways a non-local contractor would not anticipate - roughly half of all housing units in Norman are renter-occupied, which means many single-family homes near campus in neighborhoods like Chautauqua and College Addition have had rotating tenants for decades and may have deferred maintenance, disturbed insulation, or incomplete original installation. From the older streets near downtown Norman to the neighborhoods near Lake Thunderbird on the east side, we have worked on homes across the city.
We serve all of Norman and the surrounding area. Homeowners to the north in Edmond are also part of our service territory, as are other communities throughout the Oklahoma City metro and central Oklahoma.
Reach out by phone or through the online estimate form. We ask a few quick questions about your home and the areas you want addressed. We respond within 1 business day.
We come to your Norman home, inspect the attic, crawl space, or walls, and measure the space. You receive a written quote at no charge and no obligation - this visit usually takes 30 to 60 minutes and there is no pressure to commit on the spot.
Most Norman jobs are booked within the same week. The crew arrives with all equipment and materials. Attic blown-in jobs typically finish in a few hours; larger or multi-area projects may take a full day.
When the work is done we walk you through the finished space. For spray foam projects we provide a specific re-entry time before leaving. You will have written documentation of exactly what was installed.

(405) 338-4339Norman is the third-largest city in Oklahoma, with a population of roughly 128,000 people in Cleveland County, located about 20 miles south of Oklahoma City along Interstate 35. The University of Oklahoma is the city's defining institution, enrolling around 27,000 students and employing thousands of faculty and staff. The university shapes the housing market: roughly half of all occupied housing units in Norman are renter-occupied, which is well above the national average. Neighborhoods near campus - including Chautauqua, College Addition, and the streets around Gaylord Family Oklahoma Memorial Stadium - feature homes from the 1920s through 1950s, many of which have been used as rentals for decades.
Norman has expanded steadily to the south and east, with newer subdivisions in areas like Brookhaven and Westport that were built from the 1990s through the 2010s. These homes are now 15 to 30 years old - old enough that insulation, roofing, and mechanical systems are approaching the end of their typical service lives. The city also has Lake Thunderbird State Park on its eastern edge, and the neighborhoods near the lake tend to have larger lots and newer construction. We also serve homeowners to the north in Edmond and throughout the broader Oklahoma City metro area.
