Sherman Insulation provides blown-in insulation, attic insulation, spray foam, and crawl space services to homeowners in Gunter, TX. We work throughout Grayson County and respond to new requests within one business day.

Gunter has seen a wave of new construction over the last decade, and many of those homes are already underperforming on attic insulation. Our blown-in insulation service is the fastest way to bring attic R-values up to standard in Gunter homes, working over existing material in most cases without a full tearout.
Gunter attics face intense summer heat on homes both old and new, and inadequate insulation in this area means your air conditioner runs harder and longer through the June-to-September peak. Upgrading attic insulation is the highest-impact project for most Gunter homeowners.
For Gunter homes with rim joists, crawl spaces, or hard-to-reach cavities, closed-cell spray foam provides both insulation and a moisture barrier in a single application. It is a strong option for the older in-town homes near Gunter's downtown core where air sealing and insulation need to happen together.
Grayson County clay soil retains and releases moisture with the seasons, and homes in Gunter with vented crawl spaces are directly exposed to that cycle. Crawl space insulation, paired with a vapor barrier, stops ground moisture from working its way up into your floor system.
Newer Gunter subdivision homes can have significant air leakage at penetrations, sill plates, and attic knee walls even though they look well-built from the outside. Air sealing before insulation upgrades prevents conditioned air from escaping and keeps hot attic air from cycling back into living spaces.
Some older homes near Gunter's historic downtown have original insulation that is past its useful life, compressed, or contaminated from pest activity or water intrusion. Full removal and replacement is the right starting point when the existing material is doing more harm than good.
Gunter has grown fast in recent years, with new subdivisions spreading across land that was farmland just a decade ago. That growth brings a specific set of insulation challenges. Newer homes in these subdivisions were often built to minimum code standards, which means attic insulation that technically meets the letter of the requirement but leaves real performance on the table - especially during a North Texas summer when attic temperatures can climb above 130 degrees Fahrenheit. Many buyers who moved to Gunter from the Dallas suburbs are surprised to find their energy bills higher than expected, and insufficient insulation is frequently the reason.
Gunter also has an older housing stock closer to its historic downtown core. These homes were built in an era when insulation was minimal, air sealing was not standard practice, and vapor management was an afterthought. Grayson County clay soil compounds the issue by pushing ground moisture upward through any crawl space or slab edge that lacks a proper barrier. Whether your home is a new build in a subdivision off US-75 or an older in-town property near Gunter City Park, the insulation needs are distinct, and a contractor who works here regularly understands the difference.
Our crew works throughout Gunter regularly, and we understand the local conditions that affect insulation work here. The newer subdivisions on the growing edges of town are where we see the most blown-in attic upgrades - homes that are two to fifteen years old but were built with just enough insulation to pass inspection. These are straightforward jobs, but they make a real difference to the homeowners. Closer to downtown, we encounter older homes that need a more thorough approach: air sealing first, then insulation, with attention to the floor system if there is a crawl space beneath.
Gunter sits a few miles west of US Highway 75, which connects to Sherman to the north and the growing suburbs of Allen and McKinney to the south. The Gunter Tigers are a well-known name in town, and we have worked on homes throughout the Gunter ISD area. From the newer neighborhoods on the north side of town to the older streets near the historic center, we know what the homes here look like and what they typically need. According to U.S. Census data, the large majority of Gunter homes are owner-occupied, which means most residents here are protecting a long-term investment.

(903) 294-5640Gunter is a small city in Grayson County, about 60 miles north of Dallas along the US-75 corridor. The town has roots as an agricultural community, and the older neighborhoods near the historic downtown reflect that heritage - smaller lots, mature trees, and homes that go back several decades. In recent years, Gunter has become a commuter destination for families working in McKinney, Allen, and Plano, driving rapid growth in new subdivisions on the edges of town. The result is a community where brand-new brick and stone homes sit just a few streets away from mid-century houses that have seen decades of North Texas weather. According to the Gunter, Texas Wikipedia article, the 2020 Census counted roughly 2,200 residents, a number that has continued to climb.
The Gunter Tigers and Gunter ISD are central to the community's identity, and the school district is one of the top reasons families choose to settle here rather than in larger nearby towns. Many properties in and around Gunter sit on larger lots than a typical suburban home, and some include outbuildings, detached garages, or acreage that reflects the area's rural character. Gunter is well-connected to the broader region through US-75, making it easy for our crews to reach from Sherman to the north. We also serve Van Alstyne, TX down the corridor, a town going through a similar growth pattern with its own mix of new and older housing stock.
