Insulating Homes in Denton
Spray Foam Insulation in Denton covers a university city with every kind of house. Denton's record high is 113F, set in 1954, and its record low is -6F, set on February 16, 2021, during the winter storm that left much of Texas without power. Flash floods and severe storms are frequent in spring. That range is why we pay as much attention to air sealing as to R-value here.
A college town
The University of North Texas and Texas Woman's University together enroll more than 45,000 students within city limits, and 29.2% of Denton households in 2020 were one person living alone. Many older houses near the campuses are rentals. For landlords, sealing the attic floor and blowing in to a sensible depth gives the best return per dollar.
Historic neighborhoods
The 1896 courthouse on the Denton Square is on the National Register, and older neighborhoods nearby have frame houses on pier-and-beam foundations. Those usually need ceiling sealing, deeper attic insulation and insulation under the floor. Closed-cell foam under the floor seals the gaps around pipes and wiring that let cold air in during a freeze.
Newer Denton
Newer subdivisions on the edges of the city have the attic issues common across North Texas: equipment in the attic, unsealed duct boots, open chases and uneven blown-in.

Denton Questions
Did the 2021 freeze show where my house leaks?
Often. Pipes that froze and rooms that got coldest point to air leaks and thin insulation. We can check.

Can you insulate under an older pier-and-beam house?
Yes, with closed-cell foam under the floor after checking moisture.
