Insulation for Castroville homes
Why Castroville attics need attention.
Known as the Little Alsace of Texas, Castroville has a mix of historic houses and newer homes on larger lots. Older homes often have small, hard-to-reach attics with very little insulation, while newer homes may have insulation that has settled below a comfortable depth.
We inspect the attic, measure the insulation and check for air leaks and pests. Then we explain exactly what your home needs, from added insulation to a full removal, cleaning and replacement.

- Clear written quote before any work starts

Recommended R-value
South-Central Texas sits in climate zones 2 and 3. For zones 2 and 3, ENERGY STAR recommends R-49 for an uninsulated attic and R-38 when you already have 3 to 4 inches. We measure your current depth during the free visit.

If CPS Energy is your electric provider: it pays $0.35 per sq ft for contractor-installed attic insulation on projects completed Feb 1, 2026 to Jan 31, 2027. For attics with more than 24" of clearance, the existing level must be R-14 or less and the final level R-38 or more.
Federal tax credit
The federal Energy Efficient Home Improvement Credit (25C) does not apply to insulation placed in service after December 31, 2025, so don’t plan your budget around it.
