CertainTeed Blown In Insulation in Austin: What to Know First
CertainTeed blown in insulation in Austin is an independent service we provide, with most jobs completed in a single visit. We install and repair CertainTeed loose-fill fiberglass and cellulose using the brand’s specified densities, and we give you a written price before any work starts. If your attic has settled CertainTeed insulation that’s no longer holding its R-value, or you’re building out a new space and want the CertainTeed product matched correctly, call (325) 246-2929 and we’ll tell you exactly what it’ll take.

This page is for Austin homeowners who already own or are choosing CertainTeed insulation and want a straight answer on how it performs here, what fails, and what a proper install actually costs. We are an independent CertainTeed service provider. We are not affiliated with or authorized by CertainTeed, which means we tell you what’s actually true about the product, not what a manufacturer rep wants you to hear.
How CertainTeed Products Fail – and How We Fix Them
CertainTeed makes solid insulation, but Austin’s climate finds the weak spots. Here’s what we see in attics across the city, from Allandale to Wells Branch:
- CertainTeed InsulSafe fiberglass settling below spec. InsulSafe is designed to be blown at a specific density to hit its rated R-value. When installers fluff it too light, which we see constantly in older Austin ranch homes, it settles 20-30% within five years. R-38 becomes R-26 and your upstairs bedrooms bake. Our fix: we blow additional InsulSafe or GreenFiber cellulose to restore the target R-value, measuring depth and density as we go, not just eyeballing it.
- CertainTeed TrueComfort cellulose losing its fire-retardant treatment. TrueComfort is treated with borates for fire resistance and pest deterrence. After 10-15 years in a humid Austin attic, that treatment degrades, especially near roof leaks or bathroom vents that dump moisture into the cavity. The insulation still insulates, but it’s no longer doing its secondary job. We pull the compromised material and re-blow with fresh TrueComfort or a better-suited product.
- Gaps around recessed lights and attic hatches defeating the whole system. CertainTeed insulation can’t compensate for a bad air seal. We regularly find attics in Crestview and Hyde Park where the CertainTeed material is perfectly installed, but heat pours through unsealed can lights and weather-stripped hatches. We air-seal those penetrations before we touch the insulation. That’s the difference between an insulation job and an insulation fix.
- CertainTeed OPTIMA blown-in fiberglass over a damaged vapor barrier. In homes built before 2000, the original vapor barrier under the CertainTeed material is often torn or missing entirely. Moisture from the living space rises, hits the insulation, and degrades its performance. You can’t see this from the attic hatch. We inspect the barrier as part of every CertainTeed job and repair or replace it before re-blowing.
- Mixed-material attics where someone topped CertainTeed fiberglass with cheap cellulose. This happens more than you’d think. A previous owner or flipper adds a few inches of discount cellulose over settled CertainTeed fiberglass to make it look deep. But the densities don’t mesh, the air sealing underneath was never done, and you end up with an attic that looks insulated and isn’t. We remove the mixed mess, air-seal, and start clean with one consistent CertainTeed product.
Our CertainTeed Blown In Insulation Process
Here’s how a CertainTeed blown in insulation job goes when you call Aspen Attic Insulation Austin:
- 1
Call and talk to a person. A live human answers 24/7. You describe the attic, the age of the house, and any comfort problems you’re chasing. We schedule a visit and send you the technician’s name and photo before anyone shows up.
- 2
Attic inspection and measurement. The tech arrives in a marked uniform, shows a photo ID badge, and goes up. We check existing CertainTeed material, depth, density, air leaks, ventilation, and any moisture damage. We take photos to show you what we see.
- 3
Written price before any work. You get a line-item quote covering the material type, target R-value, square footage, air sealing, and cleanup. The price you see is the price you pay. No add-ons after the fact.
- 4
The blow-in. We use calibrated blowers and blow the CertainTeed material at its specified density, checking depth markers throughout the attic to hit the R-value you paid for. We air-seal penetrations first, because insulation over a leak is still a leak.
- 5
Verification and cleanup. We walk you through the attic photos, confirm the final R-value, and make sure the hatch is sealed properly. We leave the space cleaner than we found it.
- 6
Written guarantee on every job. The 365-Day Done Right Promise covers labor and materials for a full year. If something’s not right, we come back and fix it free.
What CertainTeed Blown In Insulation Costs in Austin
Here are honest ranges for common CertainTeed blown in insulation jobs in Austin. These reflect what we’ve quoted across the city over the past few years and assume a typical single-story home:
| Scenario | Typical Cost Range |
|---|---|
| Top off existing CertainTeed fiberglass to R-38 (1,200 sq ft attic) | $1,100 – $1,800 |
| Full removal and re-blow with CertainTeed TrueComfort cellulose (1,500 sq ft attic) | $2,800 – $4,200 |
| Blow in CertainTeed InsulSafe for new construction or addition (per sq ft, installed) | $0.90 – $1.40 |
| Air sealing + CertainTeed top-off (1,000 sq ft attic) | $1,600 – $2,400 |
| Attic hatch insulation and weatherstripping | $180 – $350 |
What moves the price: attic accessibility, how much settled material needs removal, whether your hatch is adequate, and how much air sealing we need to do. Austin attics with vaulted ceilings or sloped roof lines run higher because the install is slower. We encourage you to call (325) 246-2929 for a written quote based on your actual attic. The estimate is free, and the price is fixed before we start.

FAQs
CertainTeed’s manufacturer warranty applies to the material itself, not the installation labor. When we install CertainTeed blown in insulation, the material warranty stays intact, but our 365-Day Done Right Promise covers the installation in writing. If the install fails within a year, we return and fix it free. Call (325) 246-2929 and we’ll walk you through what the manufacturer will and won’t cover in your situation.
If the existing CertainTeed material is dry, pest-free, and just settled, topping it off is usually the right call and costs less than half of a full replacement. If there’s moisture damage, rodent contamination, or the fire retardant has degraded, we recommend removal and a fresh blow. We’ll show you photos of your attic so you can make the call with your own eyes.
We schedule most CertainTeed blown in insulation jobs within a few days of your call, and we answer the phone 24/7 if you need to reach a person right now. Same-week availability is common outside of peak summer demand. Call (325) 246-2929 and we’ll give you a real schedule window, not a vague range.
Yes. We carry CertainTeed InsulSafe and TrueComfort, and we can match the product already in your attic.
