Attic Insulation in Waco, TX

The attic is where most homes lose the most energy. In McLennan County's climate, the attic is the primary boundary between outdoor heat and your living space — and if the insulation there is thin, compressed, or missing in areas, your air conditioner is paying for it every month. We upgrade attic insulation for homeowners throughout Waco and McLennan County.

Recommended R-Values for McLennan County

The Department of Energy recommends R-38 to R-60 for attics in this climate zone — depending on the existing insulation type and your HVAC efficiency goals. Most older homes in McLennan County have well under this range, particularly those built before the 1990s. We measure your current depth, calculate your existing R-value, and tell you how much to add to reach the recommended level.

Air Sealing Before Adding Insulation

Adding insulation on top of an air-leaky attic floor delivers less benefit than the R-value suggests. Warm air infiltrating through gaps around light fixtures, plumbing penetrations, and attic hatches carries heat (and moisture) directly into the attic space. We seal these bypasses before adding insulation — this is what separates a proper upgrade from just dumping more material in the attic.
