Owens Corning Blown In Insulation in Austin: What to Know First
Owens Corning blown in insulation in Austin typically costs between $1,800 and $4,200 for a standard 1,500-square-foot attic, depending on existing depth, access, and whether air sealing is needed. Most jobs are completed in one day, and we provide a written price before any work starts. If your Owens Corning fiberglass has settled, gotten matted down by rodents, or was installed thin years ago, this page tells you exactly what happens next. Call (325) 246-2929 and a live person answers, 24/7.

This page is for Austin homeowners who already have Owens Corning insulation in their attic, or who are considering it for a re-insulation job, and want to know what it actually takes to get the R-value back where it belongs. Not every insulation company in Austin will tell you the truth about how Owens Corning products age in our heat. We will.
Key Takeaways

- We provide independent Owens Corning service in Austin: we install it, top it off, and fix what failed, but we are not a manufacturer-authorized dealer
- Every job gets a written price before work begins, covered by our 365-Day Done Right Promise
- Your technician’s name and photo arrive before the visit so you know exactly who is at your door
How Owens Corning Products Fail in Austin, and How We Fix Them
Austin attics reach 140°F and hotter in July. Owens Corning blown in fiberglass handles that heat fine on its own. The problem is almost always what happens to it over years of exposure to attic moisture, roof leaks, pests, and careless access from AC techs and electricians. Here are the failure modes we see most often in Austin homes:
- Settling and R-value loss: Owens Corning AttiCat blown in fiberglass, the most common loose-fill product in Austin attics, is designed to resist settling. But it still compresses over years, especially under roof traffic and storage. We regularly see attics that were blown to R-30 in the early 2000s now testing closer to R-19. The fix is a verified depth top-off, not a guess. We measure with a depth gauge, calculate the existing R-value, and blow additional AttiCat or a compatible loose-fill fiberglass to get where you need to be.
- Rodent damage and contamination: Rats and squirrels love blown in fiberglass. They tunnel through it, nest in it, and leave droppings that contaminate the material. If we find that in your Austin attic, and we do on a regular basis in older neighborhoods like Crestview and Brentwood, the fix starts with removal and sanitation before any new insulation goes in. Blowing fresh Owens Corning over contaminated material doesn’t fix the problem; it hides it.
- Compression from roof work and ductwork: Fiberglass insulation only works when it holds air. Once it’s compressed by someone crawling through the attic or setting plywood across the joists, its R-value drops fast. We see this constantly in attics with AC air handlers or ductwork installed after the original insulation. Six inches of compressed AttiCat performs like three inches. Our fix is fluffing where possible, removing and replacing where not, and setting proper walk paths so the next person through the attic doesn’t wreck it again.
- Uneven installation from the original build: Not every Austin home got the insulation it was supposed to. Some builders blew Owens Corning thin over the center of the attic and skimped at the eaves, around bathroom fans, and over garage ceilings. The homeowner’s energy bill pays for that shortcut every August. We find the shallow spots with a thermal check, mark them, and bring the whole attic to a consistent depth.
- Air leaks under the insulation: Fiberglass, including Owens Corning blown in, does not stop air movement. If the attic floor was never air sealed at penetrations, recessed lights, top plates, and chimney chases, the insulation filters the air instead of stopping it. In Austin, that means hot attic air gets pulled into the house every time the AC runs. Our standard Owens Corning blown in job in Austin includes air sealing on the specific penetrations we find. Without it, you’re paying to insulate an attic that leaks like a screen door.
Our Owens Corning Blown In Insulation Process
This is what a typical Owens Corning blown in insulation job in Austin looks like from the first call to the final walkthrough:
- 1
You call (325) 246-2929. A live person answers, asks a few pointed questions about your attic, your energy bills, and the age of the home. No voicemail tag, no call-back window.
- 2
We schedule the visit and send your tech’s name and photo. Before anyone steps on your property, you know exactly who is showing up: name, face, ID badge, marked uniform. The Threshold Standard, on every job, no exceptions. If anyone else arrives, the visit is free.
- 3
Your tech inspects the attic and tests what’s there. We check existing depth, material type, ventilation, air leaks, and pest activity. If you already have Owens Corning blown in, we’ll tell you honestly whether it needs a top-off or a full removal.
- 4
You get a written price before any work starts. The quote covers materials, labor, air sealing if it’s needed, and cleanup. No post-job surprises. You sign it before we touch the attic, or you don’t.
- 5
We do the work, usually in a single day. That means protecting the access point, removing old material if the job calls for it, air sealing, blowing Owens Corning loose-fill to the specified R-value, and verifying depth with a gauge, not a guess.
- 6
We show you the depth before we leave. Then we hand you the written 365-Day Done Right Promise. If anything fails within a year, we come back and make it right at no charge. That covers labor and materials, in writing.

Why Austin Homeowners Call Aspen Attic Insulation Austin for Owens Corning Work
Plenty of Austin insulation companies will blow fiberglass into an attic. Fewer will stand behind it for a full year, in writing, covering labor and materials. That’s the 365-Day Done Right Promise, and it’s not a marketing line. It’s a contract we hand you at the end of the job. If the insulation fails within a year, we return and fix it at no charge. No argument, no re-quote.

We also show up the way we said we would. Every technician is background-checked and identity-verified. You get the name and photo before the visit.

Garrett Sloane and his crew know Owens Corning loose-fill inside and out, because they see it in Austin attics every week.
FAQs
Topping off Owens Corning blown in fiberglass with a compatible loose-fill fiberglass product does not void your Owens Corning warranty. We use products that meet the same ASTM specifications as Owens Corning loose-fill, so the R-value and fire resistance ratings remain consistent. As an independent Owens Corning service provider, we can’t make warranty claims on Owens Corning’s behalf, but we install to the manufacturer’s stated coverage depth and bag count every time.
For an Austin attic, we recommend R-38 as the practical minimum, which translates to roughly 14 to 16 inches of settled Owens Corning loose-fill fiberglass, depending on the specific product. Homes built before the 1990s often have R-19 or less: not enough for a Austin summer. We’ll tell you what you have now and what you need after we measure it. Call (325) 246-2929 and we’ll give you a free assessment.
Yes. If you have Owens Corning AttiCat or another Owens Corning loose-fill product in your attic, we top off with a matching loose-fill fiberglass that provides the same R-value per inch. We do not mix fiberglass with cellulose in the same attic unless the situation specifically calls for it, and we’ll explain why either way.
If the existing material is dry, uncontaminated, and just shallow, a top-off is almost always cheaper than full replacement. You’re paying for the additional material and the labor to blow it in. Full removal and replacement only makes sense when there’s rodent contamination, water damage, or the existing material has been compressed beyond usefulness. We’ll show you what we find and give you a written price for whichever path makes sense.
Most Owens Corning blown in insulation jobs in Austin are scheduled within a few days, and we keep emergency slots for attics that are actively losing conditioned air or have pest damage. Call (325) 246-2929 and a live person will give you a straight answer on the schedule.
