Sherman Insulation installs attic insulation, commercial insulation, crawl space insulation, and spray foam for homeowners and businesses in Durant, OK. We know Bryan County housing and respond to new requests within one business day.

Durant has a meaningful commercial and rental property market driven by the Choctaw Nation operations and Southeastern Oklahoma State University. Our commercial insulation services cover everything from small retail spaces to warehouse buildings throughout Bryan County.
Durant's mid-20th century housing stock is the part of town where attic insulation problems show up most often. Homes from the 1950s through the 1970s were built to standards that are well below what is practical today, and settling, moisture, and pest activity have made things worse in many cases.
Bryan County clay soil holds moisture through the wet season and releases it as humidity when things dry out. Crawl space insulation paired with a vapor barrier stops that ground moisture from reaching your floor system, where it degrades insulation and damages wood framing over time.
Spray foam is a strong choice for Durant crawl spaces and hard-to-reach areas like rim joists and irregular attic geometries. Closed-cell foam provides both insulation value and a moisture barrier in one application, which is particularly useful given southeast Oklahoma's humidity.
Older Durant homes - especially those near the SE campus neighborhoods and downtown - often have significant air infiltration through attic bypasses, plumbing penetrations, and deteriorated weatherstripping. Sealing those gaps before adding insulation compounds the energy savings.
Vapor barriers are a high-value upgrade for Durant homes with unprotected crawl spaces. The combination of clay soil moisture and humid Oklahoma summers means unprotected crawl spaces are constantly fighting moisture, and a properly installed barrier removes that problem from the equation.
Durant sits in southeastern Oklahoma where summers are long, humid, and regularly push temperatures into the mid-90s. A large share of the city's housing was built between the 1940s and 1980s, when insulation standards were a fraction of what they are today. Those older brick ranch homes and wood-frame houses throughout Durant's established neighborhoods lose enormous amounts of conditioned air through under-insulated attics, unprotected crawl spaces, and walls with minimal cavity fill - and the heat and humidity make the problem worse every year. The city's rental market, which is substantial because of Southeastern Oklahoma State University, means a portion of that older housing stock has seen years of deferred maintenance on top of the original undersized installation.
Bryan County clay soil compounds the challenge from below. That soil cycles through wet and dry phases with the seasons, and without a proper vapor barrier in the crawl space, ground moisture moves into the floor system and degrades insulation from underneath. Durant also sits in a region with active spring storm seasons - hail and high winds are common from March through June, and storm damage to roofing or attic ventilation often creates insulation problems that do not show up until the next heating or cooling season. Addressing insulation in Durant means accounting for all of these factors, not just picking a material and adding it to the attic.
Our crew works throughout Durant regularly, and we understand the local conditions that affect insulation work here. Durant is the county seat of Bryan County and sits about 90 miles north of Dallas on US-69/US-75. The Southeastern Oklahoma State University campus anchors the central part of the city, and the neighborhoods around it include older homes that are some of the most common calls we get in this area. The north and east sides of town have seen new construction over the past decade, and those newer builds have their own insulation quirks - installation gaps, undersized systems, and slab-on-grade details that differ from what we see in the older housing stock near downtown.
The Choctaw Casino Resort is one of the most visible landmarks in Durant and a useful reference point for most locals. We serve properties throughout the city, from the brick homes near the old downtown core to the lake houses and cabins south of town near Lake Texoma on the Oklahoma side.
We also serve Ardmore, OK to the northwest, and Pottsboro, TX just across the state line on the Texas side of Lake Texoma. If your property is in Durant and you want an honest assessment of what your insulation actually needs, call or reach out online for a free visit.
