Blown-In Insulation in San Marcos — FAQ
What R-value should my attic have?
The DOE recommends roughly R-38 to R-60 for attics in most U.S. climates, with the higher end in colder zones. An inspection measures your existing R-value first so you only add the depth needed to reach target instead of over-insulating or guessing.
Cellulose or fiberglass, which is better?
Cellulose is denser, blocks air movement better, and uses recycled content, but it settles more over time and absorbs water if the attic leaks. Loose-fill fiberglass is lighter, settles less, and won't soak up water but allows more air movement at low densities. Both perform well installed to the correct depth; attic conditions and moisture risk decide it.
Can blown-in go on top of existing insulation?
Usually yes, as long as the existing layer is dry and not moldy or matted down. Adding over old insulation is common and effective. The bigger lever is air-sealing the gaps and penetrations first, since loose-fill slows heat transfer but does little to stop air leakage on its own.
Does blown-in insulation settle and lose R-value?
Loose-fill settles somewhat after install, which is why crews blow to a labeled coverage and depth that accounts for it; cellulose settles more than fiberglass. As long as it was installed to the rated coverage chart, the settled depth still delivers the target R-value. Compressing it later, with stored boxes or plywood decking, is what actually kills performance.
How is blown-in priced?
Mainly by attic square footage and the depth needed to hit your target R-value, plus any air-sealing or removal of contaminated old material. Difficult access and low rooflines add labor. Pricing should follow an actual attic measurement, not a phone estimate.
