Owens Corning Blown In Insulation in San Antonio: What to Know First
Owens Corning blown in insulation in San Antonio typically costs $1,400 to $3,800 for a full attic, depending on square footage, current R-value, and whether we’re topping off existing material or starting fresh. Most jobs are completed in one day, and we’re an independent Owens Corning service provider, not a factory branch, so we source the material and install it without any corporate script to follow. If you’re reading this, the odds are good your attic is either under-insulated or the existing Owens Corning fiberglass has settled, gotten damp, or been chewed through by rodents and is no longer doing its job. Call (361) 213-9499 and we’ll give you a straight answer on what’s actually happening up there.
What You Need to Know About Owens Corning Blown In Insulation in San Antonio
Owens Corning makes several blown-in products, but the two you’ll find in most San Antonio attics are AttiCat Pink Fiberglas Blown-In Insulation and ProPink blown-in fiberglass. AttiCat is the one you see at the big box stores, often sold with the free machine rental. ProPink is the contractor-grade version, usually denser and more consistent when installed with commercial equipment. Both are pink, both are fiberglass, and both work fine in theory. What matters more than the bag is what’s already in your attic and whether the install was done properly the first time. We see a lot of DIY AttiCat jobs in San Antonio where the homeowner got the coverage uneven, missed the edges entirely, or blew it so thin it barely moved the R-value. That’s not an Owens Corning problem. That’s an installation reality. We fix both.
How Owens Corning Blown In Insulation Fails in San Antonio Homes – and How We Fix It
- AttiCat Pink Fiberglas settled in older homes. Fiberglass blown-in can settle 10 to 20 percent over its first few years, especially in attics with high temperature swings. In San Antonio, where attic temps regularly hit 140°F in July and August, that settlement happens faster than in cooler climates. We see attics that started with 14 inches of AttiCat sitting at 9 or 10 inches a decade later. The fix is a top-off to restore the target R-value, usually R-38 to R-49 for our climate zone, plus an air-seal pass so the new material isn’t fighting stack-effect heat loss.
- ProPink blown-in gone thin around the perimeter. This is the most common install defect we walk into. The center of the attic has plenty of material, but the outer two feet along the soffits has almost none. That thin band around the edge is where your ceiling meets the outside wall, and it’s a major heat gain path in San Antonio summers. We blow to fill the full cavity, paying special attention to the eaves using baffles to keep airflow moving without burying the soffit vents.
- Moisture-compromised AttiCat from roof leaks or bathroom vent discharge. Owens Corning fiberglass doesn’t absorb water the way cellulose does, but it can mat down when damp, losing its loft and thermal performance. In San Antonio, we regularly find bathrooms vented directly into the attic, dumping humid air into pink fiberglass and flattening it over time. The real fix isn’t just re-blowing insulation. It’s correcting the vent termination and letting the cavity dry before adding new material. Otherwise, you’ll be back in the same spot in three years.
- Rodent damage through AttiCat and ProPink. Rats and squirrels love tunneling through loose-fill fiberglass. The tunnels create thermal voids, and the droppings create a health concern. This doesn’t happen more with Owens Corning than other brands, but homeowners in neighborhoods like Alamo Heights and Terrell Hills, with older tree canopies close to rooflines, deal with it regularly. We don’t just re-blow. We identify entry points, seal them, and then restore the insulation. It’s the only way the fix holds.
- Mixed-material mismatches where AttiCat was layered over old cellulose. Fiberglass over cellulose is fine. The problem is when the cellulose below has gone bad from moisture or pest activity and the new pink stuff is just hiding it. We’ve opened up attics in older San Antonio neighborhoods where the bottom layer was compacted, moldy, and effectively dead, but a previous contractor just blew six inches of AttiCat over it and called it a day. The correct repair is extraction, sanitation, and a clean re-blow. It’s more money up front, but it’s the only fix that actually restores performance and doesn’t create a mold sandwich.
