Attic insulation, radiant barrier and spray foam for Rio Grande City homes and buildings that take full sun all summer. Free inspection and written estimate.

Insulation for the hottest end of the Valley
Rio Grande City sits upriver in Starr County, well inland from the Gulf. Summers here run hotter and drier than in Brownsville or Harlingen, and the afternoon sun bakes roofs from spring to fall. A thin attic lets that heat straight into the house, and the AC runs nearly nonstop trying to catch up.
The city goes back to 1848, and the downtown historic district still has brick buildings by master mason Heinrich Portscheller. Most homes, though, are block and brick houses, newer homes on the edges of town, and manufactured homes on rural lots. Each one needs a different approach, so we start with a free look at the attic and tell you what makes sense.

Rio Grande City insulation FAQ
Does a radiant barrier help in Rio Grande City?
- It can. With so much sun on the roof, a radiant barrier reflects a good share of that heat away from the attic floor.
- It works with attic insulation, not instead of it. Read radiant barrier vs spray foam.
How much attic insulation should I have?
- Starr County is in climate zone 2. ENERGY STAR recommends R-49 for an uninsulated attic here, and adding R-38 when you already have 3 to 4 inches.
- We measure your attic and tell you what to add. See the best insulation for the Valley.
Do you travel out to rural properties in Starr County?
- Yes. We work on homes and buildings outside the city limits as well as in town.
- Tell us about any shops or outbuildings so we can look at them on the same visit.
