Insulation for Weslaco’s older blocks and newer subdivisions
Weslaco was platted in 1919, and the blocks around the original townsite still hold plenty of homes from the town’s early decades. Many of those houses were built long before energy codes. Their attics often have a few inches of settled insulation, or a patchwork of old batts left after years of roof and AC work.
The city has grown a lot since then, with newer subdivisions spreading north along Texas Boulevard and International Boulevard. Those homes usually got the code minimum when they were built. After a long Weslaco cooling season, owners notice the back bedrooms and the rooms under the lowest part of the roof running hot. We start with the attic, since that is where most of the heat comes in.

Weslaco insulation FAQ
How much attic insulation does a Weslaco home need?
- Weslaco 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 what you have and tell you how much to add. See R-value explained.
Should I top up my attic or replace it?
- If the old insulation is dry and clean, adding on top is usually fine.
- If it is wet, moldy or full of droppings, it should come out first. Read when removal makes sense.
Do you insulate converted garages and additions?
- Yes. These rooms often get less insulation than the main house and run hotter.
- We check the walls and the ceiling above the room, then suggest batts, blown in or foam.
What does insulation cost in Weslaco?
- It depends on the area, the material and any removal. You get a written price after a free inspection. See what affects insulation cost.
