Our Attic Insulation Services in Austin
Attic Insulation Top-Up
Top-ups are our most common call in Austin, especially in 1940s-1970s bungalows where the original batts have settled or shifted. Most top-up jobs in Austin run $1,800-$3,200. We don’t blow new material over the old without first checking what’s underneath. Collapsed rock wool, rodent damage, or moisture-stained cellulose gets documented in your photo record before we recommend adding anything on top. In neighborhoods like Brentwood and Travis Heights, we regularly find original insulation that’s performing at half its labeled R-value because air leaks through the assembly have been undercutting it for decades.
Blown-In Attic Insulation
Blown-in fiberglass or cellulose is the standard replacement for failed batts in Austin’s pier-and-beam stock. Most full attic fills run $2,400-$4,200 depending on square footage and the R-value we’re targeting. We source materials from Knauf, CertainTeed, and GreenFiber, so there’s no proprietary lock-in forcing you toward a product you didn’t choose. Every blown-in job we do in Austin includes baffles and ventilation prep first. Without them, your attic hits 150°F in July and the new insulation cooks from above while conditioned air escapes through the ceiling below.
Attic Batt Insulation
Batt jobs make sense in Austin when the attic has limited access, unusual framing, or when the homeowner needs a specific material for compatibility with an existing assembly. Rockwool batts handle Austin’s heat well and don’t degrade as quickly as some fiberglass products in extreme attic temperatures. Most batt installations in Austin run $2,200-$3,800. We cut each piece to fit the bay, not compress it in, because compressed batt loses R-value fast. Your written scope specifies the material, the R-value, and the installation method before we start.
Attic Insulation Replacement
Full replacement is the right call when the existing material is contaminated, water-damaged, or so far below modern code that a top-up won’t get you where you need to be. In Austin, this often follows a roof leak, a rodent infestation, or a homeowner who’s finally pursuing Austin Energy’s Green Building rebate and needs to hit a verified R-value and air-leakage benchmark. Most replacements run $3,200-$5,500. We remove the old material, seal the assembly, and install new insulation to the specified performance target. The blower-door test proves the number.
Attic Baffles & Ventilation Prep
This is where we start on every job that matters. Baffles keep soffit vents open so air can move across the underside of the roof deck, preventing the moisture buildup that ruins insulation from below and the heat buildup that degrades it from above. In Austin’s unvented or poorly vented attics, skipping this step means your new insulation fails early. Baffle and prep work is typically bundled into our insulation quotes, but standalone ventilation corrections run $800-$1,600. We document the baffle installation in your photo record so you can verify it was done.

Trusted Brands We Service in Austin
We stock and install materials from Knauf, Rockwool, CertainTeed, Icynene, and other major manufacturers, with no exclusive arrangement locking us into any single product line. For Austin homeowners, that means we match the material to the assembly and the performance target, not to a distributor’s quarterly push. If your Green Building rebate application requires a specific R-value or product certification, we source accordingly and document the batch numbers in your job record. Most materials are available without extended lead times, so we’re not adding weeks to your project waiting on a truck from out of state.
Common Attic Insulation Problems We See in Austin Homes
- Solar gain destroys unprotected blown-in insulation. Attics in Austin without radiant barriers or proper ventilation regularly exceed 150°F in July and August. Insulation installed without baffles or a radiant barrier first degrades faster than its rated lifespan, and the homeowner never sees the performance they paid for.
- Winter Storm Uri exposed the cold-weather gap. February 2021 froze pipes in unconditioned attics across Hyde Park, Cherrywood, and Brentwood. Homes built for heat with minimal original insulation had no thermal protection when temperatures dropped hard and stayed there. The original batts didn’t fail; they were never specified for that load.
- Pier-and-beam crawl spaces leak directly into attic assemblies. In Travis Heights and surrounding central Austin neighborhoods, open crawl spaces with zero air sealing feed unconditioned air up through wall cavities and into the attic floor. Insulation sitting on a leaky assembly performs well below its labeled R-value because air is moving through it, not just around it.
- ADU and garage conversions lack code-compliant insulation. Austin’s aggressive ADU ordinance created thousands of detached backyard cottages and garage conversions, many insulated by general contractors who stopped at the minimum or missed the attic entirely. These structures often need full retrofit to meet current code and qualify for any rebate program.

FAQs - Attic Insulation in Austin
Yes. Austin Energy’s Green Building program pays tiered rebates only when a blower-door test verifies that your attic insulation and air-sealing work hit specific R-values and air-leakage benchmarks above the Texas state energy code. No blower-door number, no rebate. We run the test before and after every qualifying job, publish both readings in your documented record, and help you file the paperwork. Call (737) 259-7528 if you want to know whether your project qualifies.
Yes. An open crawl space without air sealing undercuts attic insulation performance because unconditioned air moves up through wall cavities and leaks across the attic floor. We seal the top plates and penetrations before adding insulation, then verify the assembly with a blower-door test. In Hyde Park, Brentwood, and Travis Heights, this is standard procedure for us, not an upsell. The alternative is insulation that looks thick on paper and performs thin in practice.
Top up when the existing material is dry, uncontaminated, and structurally intact, just thin or settled. Replace when we find moisture damage, rodent contamination, compressed or collapsed batts, or when you need to hit a specific R-value that the existing material can’t reach even with additional layers. We’ll show you the photo record from your attic inspection and explain which path gets you to your performance target for the lower total cost. Free estimates mean you get that recommendation in writing before deciding.
Yes. Austin’s ADU ordinance requires these structures to meet current building code, including insulation R-values, and many were built by general contractors who stopped at the minimum or missed conditioned attic spaces entirely. We inspect ADU attics regularly in central Austin infill projects and find everything from uninsulated roof decks to batts stuffed in backwards. The fix is usually a targeted retrofit with documented R-value compliance. Call (737) 259-7528 to schedule an inspection.
Yes. A radiant barrier can reduce attic surface temperatures by 20-30°F in peak summer, which directly reduces the radiant heat load on your ducts and ceiling. Spray foam applied to the roof deck creates a conditioned attic that keeps HVAC equipment and ducts out of the 150°F zone entirely. Both are significant investments - radiant barriers typically add $1,200-$2,400 to an insulation job, spray foam attic jobs run $4,500-$8,500 - but in Austin’s climate, the cooling runtime reduction is measurable and often audible. We’ll run the numbers against your current usage and show you the payback timeline in writing.
