Fast, Reliable Blown-In Insulation Across Brushy Creek
Most blown-in insulation jobs in Brushy Creek run $1,800-$4,200 for a typical 2,000-square-foot attic, and our crews can usually inspect and price the work same-week. We’re familiar with the specific housing stock here - the late-1980s through mid-2000s brick-veneer tract homes in Cat Hollow, Brushy Creek Village, and the surrounding master-planned subdivisions - and we know what the original builder-grade insulation looks like after 20 to 40 years. Dispatch and scheduling are coordinated from our Austin office, but crews serve Brushy Creek locally. Call (737) 245-6428 for a written price before any work starts.
Why Topside Attic Insulation Cedar Park Is Brushy Creek’s Preferred Blown-In Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of them sit right here in Brushy Creek. The pattern is consistent: original blown fiberglass installed to R-19 or R-22, now settled and compressed, with HVAC air handlers creating foot-traffic dead zones that read single-digit R-values on our depth gauges. Homeowners in this area leave reviews that specifically mention the blower-door numbers we provide - they like seeing the proof in CFM50, not hearing promises about “efficiency.”
Response time to Brushy Creek is typically same-week for inspections, and we text when the technician is en route. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. Every job closes with a Documented Photo Record and, on applicable work, before-and-after blower-door readings so you can verify the air-sealing result yourself. The 365-Day Done Right Promise applies to all completed work - if it’s not done right, we make it right.
Our Blown-In Insulation Services in Brushy Creek
Blown-In Cellulose
We use GreenFiber cellulose for most full-coverage jobs in Brushy Creek. Cellulose settles less than fiberglass over time, and it performs better at the temperature extremes this climate throws at attics - 150°F in July and hard freezes like Winter Storm Uri in February. A typical Brushy Creek home running cellulose to R-49 costs between $2,400 and $4,000. We air-seal first: top plates, can lights, penetrations, and the air handler platform. Then we blow. The blower-door test shows the difference in one number.
Blown-In Fiberglass
For homeowners who prefer fiberglass, we stock Owens Corning and Johns Manville products. Fiberglass works well in Brushy Creek attics when it’s blown to proper depth and the attic floor is sealed first. We don’t blow over unsealed surfaces - that’s Haven Standard. A fiberglass top-up or replacement in a 2,000-square-foot Brushy Creek attic typically runs $1,800-$3,400. We mark depth targets on the rafters so you can verify the work yourself later.
Dense-Pack Wall Insulation
The R-13 fiberglass batts in your exterior walls are below current IECC requirements and they don’t stop air movement. Dense-pack cellulose fills the cavity completely, reducing both conductive heat loss and air infiltration. In Brushy Creek’s 1990s brick-veneer homes, this matters especially after Uri - the hard freeze exposed how thin those wall envelopes really are. Dense-pack wall work runs $2,000-$4,500 depending on home size and access. We drill, pack, and patch; the Documented Photo Record shows before, during, and after.
Blown-In Top-Up
This is the most common job we do in Cat Hollow and Brushy Creek Village. The original insulation isn’t necessarily bad - it’s just insufficient and unevenly compressed. After air-sealing the attic floor and the HVAC platform, we top up with blown cellulose or fiberglass to bring the entire space to a uniform R-49. Typical cost: $1,800-$3,200. You keep your original insulation, add the R-value you need, and get the blower-door numbers to prove the air sealing worked.

Common Blown-In Insulation Problems We See in Brushy Creek Homes
- Compressed insulation around attic air handlers. In Cat Hollow and Brushy Creek Village, the original 1990s blown fiberglass was installed to R-19/R-22, and because HVAC air handlers sit in the attic, foot traffic has compacted the insulation to single-digit R-values right around the unit while the eaves still read closer to original depth. We measure this on nearly every inspection.
- Ductwork baking in 150°F attics. Because the ductwork runs through the unconditioned attic, radiant heat gain and duct leakage overwhelm the thin original insulation, forcing the AC to run longer and masking the fact that the insulation itself is the root problem. The homeowner calls the HVAC company; the real fix is in the envelope.
- Wall batts failing during hard freezes. Winter Storm Uri exposed how R-13 wall batts and shallow attic insulation fail to hold heat in these brick-veneer tract homes, leading to burst pipes in exterior walls. The thermal envelope was built to minimal 1990s Texas codes, and it shows when the temperature drops below 20°F.
- Settled fiberglass creating uneven coverage. Over 20-40 years, blown fiberglass settles and shifts, creating thin spots and bare patches. We find this especially above master-bedroom ceilings and near attic access hatches where previous technicians have walked repeatedly without replacing the displaced material.

FAQs - Blown-In Insulation in Brushy Creek
A top-up is usually sufficient if the original fiberglass is dry, uncontaminated, and reasonably distributed. We air-seal the attic floor first, then blow new material over the old to bring everything to a uniform R-49. Full removal is only necessary if there’s rodent damage, water staining, or significant mold - we’ll photograph what we find and show you before recommending anything. Call (737) 245-6428 for a free inspection and written price.
Because technicians and homeowners have walked on it for 20-30 years, compressing the fiberglass to a fraction of its original depth. We were in Cat Hollow on a two-story brick-veneer home where the original blown fiberglass had settled so badly around the attic air handler that the depth gauge read barely 3 inches near the service platform, while the eaves still showed 9 inches. After air-sealing the top plates and the unit platform, we topped up with GreenFiber cellulose to bring the entire attic to a uniform R-49. The homeowner told us the upstairs bonus room finally stopped running 5 degrees warmer than the rest of the house. Call (737) 245-6428 - we’ll measure your depths and show you the photos.
Start with the attic and air sealing - that’s where the biggest return is in Brushy Creek’s climate. But if you had frozen pipes in exterior walls during Uri, dense-pack wall insulation is worth considering. The R-13 batts in your 1990s walls don’t stop air movement, and cellulose packed at 3.5 pounds per cubic foot does both. We can price the attic and walls together or separately; either way, you get a written scope before any work starts.
R-49 for attics, which is the current IECC recommendation for Climate Zone 2A. Your 1996 home was built to R-19 or R-22, so you’re likely undersized by roughly half. R-13 walls can be improved with dense-pack to approximately R-15 plus air sealing, which matters more than the raw R-value number suggests. We’ll specify the target on every written price.
Gray, dusty fiberglass is usually just aged - fiberglass dulls over time as it filters attic air. It’s not automatically a health hazard or a performance problem. What matters is depth, evenness, and whether the attic floor is sealed. We inspect and photograph before recommending anything. If the dust layer is extreme or there’s debris from old ductwork or rodent activity, we’ll flag it. Call (737) 245-6428 for a free inspection - estimates are free, and the written price comes before any work.
