Icynene Blown In Insulation in Austin: What to Know First
Icynene blown in insulation work in Austin typically runs $1.35 to $2.80 per square foot installed, and most attic jobs we take on are done in a single day. We’re an independent Icynene service provider, not a manufacturer-authorized dealer, which means we repair and install what’s actually best for your home rather than what a brand rep wants sold. If you own a home with Icynene already in the attic and it’s underperforming, or you’re adding blown in insulation to a Icynene-sealed house, call (325) 246-2929 and we’ll give you a written price before anything goes in.

This page is for Austin homeowners who have Icynene foam in their attic or walls and need to understand why it’s not holding heat out, what a real fix costs in this city, and who they can trust to do the work without surprises at the door or on the invoice.
How Icynene Products Fail – and How We Fix Them
Icynene spray foam earned a strong name in Austin for a reason. But like every product installed in a 105-degree attic, it has weak points we see over and over. Here are the five most common Icynene failures we repair, along with what actually causes them and what we do about it.
- Gaps and shrinkage in Icynene Classic open-cell foam. Icynene Classic (now sold as Icynene Classic Ultra) is an open-cell, water-blown foam that can shrink slightly over years of Austin’s extreme heat cycling. When it pulls away from rafters or top plates, a channel opens for attic air to bypass the insulation entirely. We reseal those gaps with compatible blown-in insulation packed tight against the foam, or we re-foam the seam with a compatible product. If you’re losing conditioned air through the attic, this is the first place we look.
- Icynene ProSeal closed-cell foam that’s under-applied at the eaves. ProSeal (also known as Icynene ProSeal LE) is a closed-cell product often specified for the roofline in unvented attics. Contractors sometimes spray it thin at the edges near the soffit vents, leaving a thermal bridge. We see this constantly in older Austin ranch homes. The fix is adding blown-in insulation over the problem area to restore the R-value without tearing out the existing foam.
- Pest damage in open-cell Icynene. Squirrels and roof rats love tunneling through open-cell foam, and Austin has plenty of both. Once Icynene Classic is burrowed through, the insulation value drops fast. We remove the shredded sections, seal the entry point, and install fresh blown-in loose fill in the affected zones. If the foam is too far gone, we’ll tell you plainly and quote replacement.
- Improper installation from day one. Some Austin homes had Icynene installed during the 2000s boom by crews who rushed the job. We find uneven depth, thin spots, and foam that never fully cured. The real problem is you can’t always see it from the attic hatch. We do a full inspection with thermal imaging to find the shallow spots, then build up the layer with blown-in fiberglass or cellulose to hit the R-value the home needs.
- Foam separated from the decking after hail or roof replacement. A new roof tear-off can physically shock the roof deck and break the mechanical bond between Icynene and the sheathing. If your roofer didn’t flag it, you may not know until your electric bill climbs. We re-adhere where possible and add blown-in insulation to close the air gap and keep your cooling dollars in the house.
Our Icynene Blown In Insulation Process
Here’s what a Icynene blown in insulation job looks like with us, from first call to the guarantee in your hand.
- 1
You call (325) 246-2929. A live person answers. We get your address, ask about your Icynene setup, and schedule a time that works for you. Before the visit, we send the technician’s name and photo by text or email so you know exactly who’s coming.
- 2
We inspect the full attic. Our tech checks the Icynene condition, measures existing R-value, looks for gaps, pest damage, moisture, and ventilation problems. We use a thermal camera in most cases to find what the eye misses.
- 3
You get a written price. Before any work starts, we hand you a line-item quote showing exactly what we’ll do, what materials go in, and what it costs. No deposit games, no after-the-fact extras.
- 4
We install the blown-in insulation. For Icynene homes, we typically use fiberglass loose fill from Owens Corning or Johns Manville, or cellulose where it makes sense. The material gets blown to the correct depth and density for the R-value target, and we pack it tight into all transitions where foam meets framing.
- 5
We verify and test. Tech checks final depth against the written spec, confirms the air seal at all seams and penetrations, and documents the job with photos.
- 6
You get the 365-Day Done Right Promise in writing. It covers labor and materials for a full year. If something isn’t right, we come back free and fix it. No fine print beyond that.
What Icynene Blown In Insulation Costs in Austin
Icynene blown in insulation pricing in Austin depends on the area, the depth required, and the condition of the existing foam. Here’s what we typically quote:
- Adding blown-in over existing Icynene in a 1,200-1,500 sq ft attic: $1,600 to $4,200 total, installed
- Full attic re-insulation with blown-in loose fill (foam removed or abandoned): $2,800 to $7,500 total depending on R-value target and attic size
- Spot repair around Icynene gaps or pest damage: $350 to $950 per zone
- Thermal imaging inspection with written recommendation: $150 to $350 (credited toward the job if you hire us)
What moves the price: attic square footage, target R-value, whether old foam must be removed, accessibility, and whether we’re working around stored belongings. We give the price in writing before work starts, always. Call (325) 246-2929 and we’ll come out, inspect the attic, and quote the job so you know the real number before you commit.
Why Austin Homeowners Call Aspen Attic Insulation Austin for Icynene Work
Garrett Sloane has been in Austin attics long enough to know that a Icynene job done wrong is worse than one done never. He grew up in Los Angeles, learned insulation through the building construction program at LA Trade-Technical College, and has spent years working Central Texas homes, from older Allandale ranch houses to new builds near the Domain. If your attic’s working against you, your AC never wins. We send a named, photo-badged technician in a marked uniform to every visit. They’re background-checked and verified through the Threshold Standard, the protocol Aspen Attic Insulation Austin has operated under since 2002. We also keep Reflectix and other brands on hand for situations where a radiant barrier or reflective layer is the smarter move than more blown-in fill. You hire us, you get the right material for the problem, not the material we’re trying to unload.
FAQs
Adding blown-in insulation over existing Icynene foam does not void the Icynene manufacturer’s warranty in most cases, because the foam itself isn’t being altered. What can void a warranty is cutting into the foam or applying incompatible chemicals on top of it. We use only blown-in loose fill products that are chemically compatible with both open-cell and closed-cell Icynene lines. Before we touch anything, we document the existing foam condition with photos so you have a record if a warranty claim ever comes up. Call (325) 246-2929 and we’ll walk through your specific setup.
We do both: we repair damaged or separated Icynene and we install blown-in insulation where it’s needed to restore full attic performance. Some jobs are purely a foam repair, others are purely blown-in, and a lot of Austin homes need both. We’ll tell you which applies after inspection and quote it in writing.
In most cases we can schedule an inspection within 2 to 4 business days, and the actual blown-in installation is usually completed the same day we start. If you call (325) 246-2929, a live person answers 24/7 and can get a tech scheduled while you’re on the phone.
In Austin, it depends on the condition of the foam. If the Icynene is mostly intact with a few gaps or pest-damaged zones, repair plus targeted blown-in is almost always the better value, usually $1,500 to $3,000 cheaper than full removal. If the foam is badly separated, saturated, or more than 30 percent compromised, removing and starting fresh with blown-in loose fill is the honest recommendation. We give both options in writing and let you choose.
Yes, we service homes with both Icynene ProSeal (closed-cell) and Icynene Classic (open-cell) installed, along with the older ProSeal LE formulation. Each has different failure modes and repair approaches, and our techs are trained on the distinctions. We also stock compatible blown-in materials in our Austin operations so the job doesn’t stall waiting on a distributor.
