Our crews are dispatched from our Austin office and can usually inspect your attic within 24 to 48 hours of your call.

Call (737) 245-6428 to schedule a free attic inspection with a written price before any work starts.
Why Topside Attic Insulation Cedar Park Is Austin’s Preferred Blown-In Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of that work has been right here in Austin. Our crews know the difference between a pier-and-beam bungalow in Travis Heights and a slab-on-grade ranch in North Austin, and we price accordingly rather than applying a one-size-fits-all formula.
Our reviews from Austin customers consistently mention two things: the blower-door numbers we leave behind, and the fact that we actually show up when we say we will. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
Response time to Austin addresses is typically same-day or next-day for inspections, with blown-in installation scheduled within a week once the written scope is approved. We do not use callback windows measured in business days. A live person answers calls 24/7.
What separates us in this market is our refusal to blow insulation over an unsealed attic floor. In Austin’s 150°F summer attics, air sealing top plates, can lights, and duct penetrations is not an upsell. It is a prerequisite. We will not start blowing until it is done.
Our Blown-In Insulation Services in Austin
Blown-In Cellulose
We install GreenFiber cellulose in Austin attics where fire resistance and sound dampening matter, which is most of them. Cellulose is treated with borate for pest and fire resistance, and it performs well in Austin’s humid Climate Zone 2A conditions when paired with proper attic ventilation. Most Austin attic top-ups with cellulose run $2.20 to $3.00 per square foot installed. We were called to a 1950s pier-and-beam bungalow in Travis Heights where the attic had original rockwool insulation that had compacted to less than R-5, and the walls were completely empty. After a quick vermiculite test came back clean, our crew dense-packed the wall cavities with GreenFiber cellulose and blew in Owens Corning fiberglass to bring the attic to R-49, then air-sealed the top plates. The homeowner immediately noticed the AC cycling less, and we scheduled a follow-up to check the under-floor area for the same issue.
Blown-In Fiberglass
Our Blown-In Insulation team installs Owens Corning and Johns Manville fiberglass in Austin homes where moisture management and long-term R-value stability are priorities. Fiberglass does not absorb moisture the way cellulose can, which matters in Austin’s spring and fall humidity spikes. In the 1980s to 2000s slab-on-grade homes that dominate North and South Austin, we frequently pair blown-in fiberglass attic insulation with targeted duct sealing because those HVAC air handlers sitting in 150°F attics will destroy your effective R-value if the ducts are leaking. Typical fiberglass attic installations in Austin run $1.80 to $2.80 per square foot.
Dense-Pack Wall Insulation
Austin’s central-city pier-and-beam bungalows in Hyde Park, Bouldin Creek, and Travis Heights often have empty wall cavities. No insulation at all. We dense-pack these walls with cellulose or fiberglass at 3.5 to 4.0 pounds per cubic foot, creating an air-impermeable barrier that stops convection currents without removing interior drywall. This is specialized work. The material must be installed at precise density or it will settle and leave gaps at the top plate. Our crews have done hundreds of these in Austin’s older neighborhoods. Dense-pack wall jobs typically range from $3,200 to $6,500 for a full home, depending on wall area and access.
Blown-In Top-Up
Not every Austin attic needs full removal. In newer subdivisions across Round Rock and Pflugerville, and in some South Austin builds from the 2000s, existing fiberglass batts may simply be under-depth or poorly distributed. We inspect, measure settled depth, and calculate whether a top-up to current R-49 (or R-60 for Austin Energy rebate-eligible jobs) makes sense versus full replacement. A blown-in top-up in Austin usually runs $1,400 to $3,200. We will tell you honestly if your existing insulation is too compressed, too contaminated, or too poorly air-sealed to justify topping off.

Trusted Brands We Service in Austin
We source materials from Owens Corning, Johns Manville, Knauf, and GreenFiber, among others. No proprietary product lock-in means we specify what actually fits your attic’s condition and your home’s age, not what a manufacturer is pushing this quarter. Our Austin warehouse stocks standard blown-in fiberglass and cellulose for same-week installation on approved jobs. Specialty materials like Rockwool or high-density spray foam components are typically two to three days out. We do not claim exclusive or preferred status with any brand. We claim the right to choose the right material.
Common Blown-In Insulation Problems We See in Austin Homes
- Compacted rockwool in pre-1980 central Austin attics. Original blown-in rockwool settles and loses effective R-value, often dropping below R-5, leaving the top plate and attic floor unevenly covered. In central Austin zip codes like 78757 (Crestview/North Loop), attics frequently contain original 1970s blown-in rockwool that has compacted to near-zero effective R-value and is sometimes laced with vermiculite, so local crews treat hazmat assessment as a mandatory line item before any blown-in work-something not typical in newer suburban markets.
- HVAC air handler and ductwork in unconditioned attics. 1980s to 2000s slab-on-grade homes across North and South Austin commonly have leaky ducts and air handlers in 150 to 160°F attics, which undermines any blown-in insulation unless the ducts are sealed and the attic is encapsulated. Austin’s extraordinary cooling burden makes this a dominant retrofit strategy unique in its scale to this market.
- Vermiculite contamination in older neighborhoods. Crestview, North Loop, and similar zip codes frequently reveal vermiculite-laced patches in original insulation during attic inspections, requiring hazmat assessment and often full removal before new blown-in material can be installed. We price this inspection into every attic quote in those neighborhoods.
- Post-Uri demand for higher R-values. The February 2021 Winter Storm Uri, which drove Austin temps to historic lows and caused widespread pipe failures, exposed how catastrophically under-insulated most Texas homes are on the heating side. Homeowners are now requesting R-49 and R-60 attic values in numbers we did not see before 2021.

FAQs - Blown-In Insulation in Austin
No. We will not blow new insulation over original 1970s rockwool in Crestview or North Loop without first testing for vermiculite and assessing whether the existing material has compacted below useful R-value. In most 78757 attics we inspect, the original rockwool has settled to near-zero effectiveness and requires removal. Call (737) 245-6428 for a free inspection and written scope.
Austin’s combination of 150°F summer attics, municipally-funded Austin Energy rebates for conditioned-attic encapsulation, and a massive stock of 1970s to 2000s homes with HVAC equipment in those hot attics creates a retrofit market unlike Houston, Dallas, or San Antonio. Neighboring cities served by private utilities cannot match Austin Energy’s rebate structure for spray foam encapsulation. Call (737) 245-6428 to discuss whether your home qualifies.
Yes. We treat hazmat assessment as mandatory in North Loop, Crestview, and similar central Austin zip codes with pre-1980 housing stock. The test is quick and included in our inspection fee. If vermiculite is present, we coordinate certified removal before any new blown-in material goes in. Call (737) 245-6428 to schedule.
Current Austin Energy guidelines recommend R-49 to R-60 for attic insulation in this climate zone, a significant jump from the R-19 to R-30 commonly installed in 1980s to 2000s construction. Post-Uri, we are seeing more homeowners request R-60 for the heating-side protection. Your written scope will specify the target and the measured depth required to achieve it. Call (737) 245-6428 for a free assessment.
Yes. We dense-pack wall cavities in Austin’s pier-and-beam bungalows from the 1940s to 1960s, including Hyde Park, Travis Heights, and Bouldin Creek. The technique requires drilling small exterior holes or accessing from the attic, then packing cellulose or fiberglass at 3.5 to 4.0 pounds per cubic foot. No interior drywall removal needed in most cases. Call (737) 245-6428 for a written price on your specific home.
