We called on a Monday and had the crew out by Thursday. They blew in new insulation to bring our attic up to the right depth, and the upstairs bedrooms are finally comfortable this summer. The whole job took about three hours, and they cleaned up after themselves.
Sarah M., Stillwater - Attic insulation
Our crawl space was damp and musty, and we were worried about mold. The team installed closed-cell spray foam on the walls and a vapor barrier on the floor. The smell is gone, and our home feels tighter. They explained everything they were doing as they went.
Tom L., Edmond - Crawl space insulation
We had spray foam installed in our attic during a new addition, and the difference in temperature between the old and new parts of the house was noticeable. We ended up having them come back to do the rest of the attic. Our cooling bills dropped by about 20 percent that first summer.

The U.S. Department of Energy recommends R-49 to R-60 for attics in Oklahoma, which is roughly 13 to 16 inches of blown-in material. Most homes built before 1990 fall well short of that target, and the gap shows up every summer and winter on your utility bill.
On a 100°F afternoon in July, your attic can reach 150°F or more. Without enough insulation, that heat radiates straight down into your living space, forcing your air conditioner to work overtime. Proper attic insulation slows that heat transfer and keeps your home comfortable.
Spray foam seals air gaps and delivers the highest R-value per inch, which makes it ideal for crawl spaces, rim joists, and walls. Blown-in insulation is cost-effective for attics and fills irregular spaces that batts cannot reach. The right choice depends on where heat is escaping from your home.
Insulation slows heat transfer, but it does not stop air from moving through gaps around light fixtures, pipes, and wiring. A good contractor air-seals those penetrations before adding insulation. According to the U.S. Department of Energy, this step can reduce heating and cooling costs by up to 15 percent.
If existing insulation is wet, moldy, or pest-damaged, it needs to come out before new material goes in. Adding on top of damaged insulation traps moisture and makes the problem worse. If your insulation is simply old and thin, a contractor can often blow new material right over it to bring coverage up to the right level.
North-central Oklahoma sits on expansive clay soils that hold moisture and shift with wet and dry seasons. That moisture migrates upward into crawl spaces, causing musty smells, wood rot, and higher indoor humidity. Insulating and sealing crawl space walls stops that cycle before it damages your home.
Stillwater Insulation is a licensed, insured insulation contractor based in Stillwater, OK, serving homeowners and businesses across 12 cities in central Oklahoma since 2025. We are licensed by the Oklahoma Construction Industries Board and carry full general liability and workers compensation insurance. Our team has completed hundreds of insulation projects across Payne, Oklahoma, and Cleveland counties, from attic top-offs to whole-home spray foam installations.
If existing insulation is moldy, wet, or damaged by pests, it should be removed before new material goes in. If it is simply old and thin, a contractor can often add new insulation on top to bring coverage up to the right level. A good contractor will inspect what you have and tell you which approach makes sense.
Most homeowners start to notice a difference on their first full heating or cooling bill after insulation is installed. Homes with very poor existing insulation often see larger savings in the first year. The ENERGY STAR program estimates payback periods of three to seven years for most insulation upgrades.
Insulation can be installed any time of year. Summer attic work can be uncomfortable for the crew, but it is safe and effective. Fall is popular in Stillwater because homeowners want to get ahead of winter heating costs, and contractors tend to have more availability than during the peak summer rush.

Stillwater is a mid-sized city of about 50,000 people in north-central Oklahoma, located in Payne County on mostly flat to gently rolling prairie. The city is home to Oklahoma State University, which enrolls around 25,000 students and shapes much of the local economy and housing market. Stillwater has a mix of older in-town neighborhoods near campus - many built in the 1950s through 1980s - and newer subdivisions on the south and west sides of town that have grown steadily over the past 30 years.
The city's downtown historic district on Main Street features older brick commercial buildings and is a gathering spot for locals and students. Neighborhoods around Boone Pickens Stadium and the OSU campus have a high concentration of rental properties, while the southern and western parts of the city are mostly owner-occupied single-family homes. The median home value in Stillwater sits around $175,000 to $185,000, which is below the national median but in line with much of Oklahoma. Stillwater Creek runs through the area, and the flat terrain means drainage and foundation movement on clay soils are common concerns for homeowners.
Whether you live near the OSU campus, in one of Stillwater's older neighborhoods like College Hill and Westwood, or in a newer subdivision on the outskirts, Stillwater Insulation knows the local housing stock and the insulation challenges that come with it. We serve homeowners and businesses all across Stillwater and the surrounding region, and we respond to all estimate requests within 1 business day.
