Insulating Homes in the County Seat
Spray Foam Insulation in Sulphur Springs starts with the weather. The city's climate table on Wikipedia, based on 1991-2020 normals, lists an average daily high of 94.9F in August, a record high of 115F and about 46.5 inches of rain a year. It also lists an average January low of 34.0F and a record low of -12F. That mix of long, humid summers and short but real cold snaps is why sealing the house matters as much as adding R-value.
A town that grew in stages
Sulphur Springs became a city in 1854, when its first post office opened under the name Bright Star, and it became the Hopkins County seat in 1871. Railroads arrived from Mineola in 1872 and the Cotton Belt line followed in 1887, and the town grew again after World War II as new plants and factories came in. That history shows up in the housing: older frame homes near downtown, post-war and mid-century houses across the middle of town, and newer subdivisions and homes on acreage at the edges. The 2020 census counted 6,966 housing units in the city.
Dairy country around town
The dairy industry was a big part of the local economy from the late 1940s through 1995, and the Southwest Dairy Museum in town tells that story. Many of the old dairy barns and the newer steel shops on surrounding farms are the kind of buildings that sweat and bake without insulation. Closed-cell foam on the steel is our usual fix there.
What we usually find in town
In older houses near the square: thin attic insulation, open wall tops, little or nothing under pier-and-beam floors. In ranch houses from the 1960s through the 1990s: settled blown-in, leaky duct boots and an air handler in a hot attic. In newer homes: attics that meet older code minimums but run hot because ducts sit above the insulation. Each one leads to a different quote.
