Stillwater Insulation serves Bartlesville, OK with spray foam, attic insulation, and blown-in insulation for older homes and postwar construction throughout Washington County. We are a licensed insulation contractor and respond within 1 business day.

Spray foam insulation is a strong match for Bartlesville's older housing stock because it fills irregular spaces around original wood framing, brick veneer cavities, and low crawl spaces without requiring the precise fitting that batts demand. Our team installs closed-cell and open-cell spray foam throughout Washington County for homes ranging from 1920s craftsman bungalows to 1960s brick ranches.
A large share of Bartlesville homes built before 1970 have attic insulation that has been in place for decades, often settling to a small fraction of its original thickness. Bringing those attics up to current R-value recommendations is one of the most direct ways to reduce heating and cooling costs in northeast Oklahoma's climate of hot summers and freeze-thaw winters.
Blown-in loose-fill insulation works particularly well in older Bartlesville homes because it can be added over whatever is already in the attic without removing the original material - a practical advantage when the existing batts are still intact but simply too thin. It fills around wiring, HVAC ducts, and framing members that were placed without modern insulation in mind.
Many mid-century Bartlesville homes sit on shallow crawl spaces that were never insulated, leaving first-floor rooms cold in winter and susceptible to moisture from the clay soils below. Insulating and conditioning the crawl space protects the floor structure and makes a noticeable difference in comfort for the rooms directly above.
Older Bartlesville homes - particularly those built before 1960 - often have little or no wall insulation. For homes with wood siding or brick veneer, blown-in wall insulation can be added through small access holes that are patched after installation, improving comfort without requiring a full gut renovation.
Bartlesville's housing stock is older than most cities its size in Oklahoma. Census data shows a significant share of the city's homes were built before 1970, and many go back to the 1940s and 1950s. Homes from that era were built with minimal insulation by today's standards - often just a thin layer of rock wool batts in the attic and no wall or crawl space insulation at all. Decades of settling, moisture exposure, and pest activity have reduced even that original material further. The result is that many Bartlesville homeowners are heating and cooling homes that are far less efficient than they appear from the outside.
Bartlesville's climate adds pressure to that situation. Winters see average lows in the mid-20s Fahrenheit, with repeated freeze-thaw cycles from November through March that stress masonry, foundations, and roofing. Summers reach the low-to-mid 90s with humidity, and severe thunderstorms with hail hit the area every spring. The clay-heavy soil throughout Washington County expands and contracts with seasonal moisture changes, which drives moisture into crawl spaces and pushes against shallow slab foundations. An insulation contractor who understands these conditions will assess your home differently than one who simply measures square footage.
Working in Bartlesville means working in a city where most homes predate modern energy codes by several decades. Our crew pulls permits through the City of Bartlesville when required, and we are familiar with the mix of older brick ranch homes, craftsman bungalows, and postwar construction that makes up most of the city. Working in homes from the 1940s through 1960s requires a different approach than subdivision work - you find original framing, uneven surfaces, and insulation configurations that were standard decades ago but are not common today.
Bartlesville is centered around its distinctive downtown, with older residential neighborhoods surrounding the core and postwar subdivisions spreading outward from there. The city serves as the Washington County seat, which means it draws homeowners from smaller surrounding communities like Dewey and Copan who look to Bartlesville contractors for work they cannot find locally. Our crew is familiar with the full range of construction you find throughout Washington County.
We serve Bartlesville homeowners as part of our northeast Oklahoma coverage, and also work regularly in Owasso to the south, where the newer construction presents a different but equally common set of insulation challenges.
Contact us by phone or online and describe your Bartlesville home and what you are looking to address. We respond within 1 business day and schedule a free site visit at your convenience.
We come to your home, inspect the attic, crawl space, or walls, and document what is there. For older homes, this step often uncovers issues that are not visible from the outside. You get a written quote before any commitment.
Most Bartlesville jobs are scheduled within the same week. The crew arrives with all materials and equipment. Older homes may require a removal step before new insulation goes in - we walk you through that timeline clearly.
After the work is done we walk through the finished space with you and provide written documentation of what was installed and to what specifications. For spray foam jobs, we provide a specific re-entry time before we leave.

(405) 338-4339Bartlesville is a city of about 36,000 people in Washington County in northeastern Oklahoma, roughly 47 miles north of Tulsa. The city has deep ties to the oil industry - it was home to Phillips Petroleum Company for decades, and ConocoPhillips still maintains a significant presence there today. That economic stability helped Bartlesville develop a solid stock of owner-occupied homes over multiple generations, from craftsman bungalows near downtown to mid-century brick ranches in the postwar subdivisions. Johnstone Park along the Caney River is one of the city's longtime gathering spots, and the surrounding neighborhoods reflect the character of a city that has stayed largely consistent in size and character over the past 50 years.
Residential neighborhoods in Bartlesville range from the walkable blocks near downtown - where you find homes from the early 1900s through the 1930s on established lots with mature trees - to the postwar subdivisions that spread outward in the 1950s and 1960s, and a smaller number of newer homes on the edges of town. Most lots are mid-size with mature landscaping. The owner-occupancy rate is relatively high for a city of this size, which means many Bartlesville homeowners have held their properties for years and are ready to make improvements. We also work with homeowners in nearby communities, and cover Claremore and other parts of northeastern Oklahoma as part of our service area.
A large share of Bartlesville homes were built before 1970, and working in that era of construction requires a different approach than subdivision work. We know the original framing patterns, the common insulation deficiencies in postwar brick ranches, and how to work around the constraints of older homes without creating new problems.
Every estimate is documented in writing before work begins. We will not ask you to decide on the spot. For older homes where the full scope is not clear until the attic or crawl space is inspected, we will explain any adjustments to the quote before we proceed.
