Fast, Reliable Blown-In Insulation Across Shady Hollow
Blown-in insulation in Shady Hollow typically runs $1,800-$4,200 for a full attic, depending on whether we’re topping up settled material or starting fresh after air sealing. Most jobs finish in a single day, and crews dispatched from our Austin office usually reach Shady Hollow properties within 45 minutes. If your home was built between the late 1970s and mid-1990s, the original insulation has likely compressed to a fraction of its labeled R-value, and you’re paying for cooling load that proper blown-in coverage would eliminate.
We know these houses. The slab-on-grade construction, the vented attics, the original blown-in fiberglass that’s now a thin crust over your ceiling drywall. Our Blown-In Insulation team treats Shady Hollow as a core service area, not a distant add-on.

Why Topside Attic Insulation Georgetown Is Shady Hollow’s Preferred Blown-In Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a growing share of them sit in Shady Hollow’s mature canopy. Reviews from Shady Hollow customers consistently mention two things: the blower-door numbers we leave behind, and the photo documentation that shows what was actually done in their attic. Our 365-Day Done Right Promise applies to every job, backed by a written scope and warranty delivered before any work starts.
Response time matters in July, when your attic hits 150°F and your AC runs nonstop. Crews leave our Austin dispatch point and reach Shady Hollow in under an hour. We carry Owens Corning, Johns Manville, Knauf, and GreenFiber materials on our trucks, so we don’t waste a trip ordering product.
Shady Hollow’s unincorporated Travis County status creates specific permit and code requirements that differ from Austin-proper jobs. We’ve navigated those pathways repeatedly. When a previous retrofit lacks proper documentation, we know how to bring the job into compliance without unnecessary rework.
Our Blown-In Insulation Services in Shady Hollow

Blown-In Cellulose
We use GreenFiber cellulose on most Shady Hollow attics because it performs well in our hot, humid Climate Zone 2 summers and settles less than fiberglass over decades. A typical full-coverage job in a 2,000-square-foot Shady Hollow attic runs $2,400-$3,800, including air sealing of top plates and can-light penetrations. Cellulose’s higher density also blocks air movement better than loose fiberglass, which matters when your attic hits 140-160°F and every crack becomes a thermal leak.

Blown-In Fiberglass
For homeowners who prefer synthetic material, we stock Owens Corning and Johns Manville loose-fill fiberglass. In Shady Hollow’s older homes, we often use fiberglass for top-ups when the existing layer is clean and uncompressed. A fiberglass top-up to reach R-38 typically costs $1,800-$2,800. We never blow new material over debris, moisture, or unsealed air leaks - that’s Haven Standard, and it’s non-negotiable.

Dense-Pack Wall Insulation
Shady Hollow’s 1980s slab-on-grade homes were built with empty stud cavities or minimal batt insulation in exterior walls. Dense-pack cellulose, blown at 3.5 pounds per cubic foot, fills those cavities completely and cuts air infiltration through the wall assembly. This service runs $2,200-$4,500 depending on wall area and accessibility. After Winter Storm Uri, we’ve fielded more calls about this from Shady Hollow homeowners who felt how poorly their walls performed during the freeze.

Blown-In Top-Up
This is our most common Shady Hollow service. Original blown-in fiberglass from the 1980s and 1990s has settled to 3-5 inches, often achieving only R-11-R-15. We remove debris, air-seal the attic floor, then blow in material to reach R-38 to R-49 per current Austin Energy guidance. Most Shady Hollow top-ups cost $1,800-$3,200. We recently topped up a 1984 slab-on-grade home near Brodie Lane where the original blown-in fiberglass had settled to about 4 inches, and the eave bays were packed with live-oak leaf litter from the mature canopy. After air-sealing the top plates and baffling the soffits, we blew in GreenFiber cellulose to bring the attic to R-49, restoring even coverage across the vented attic.

Common Blown-In Insulation Problems We See in Shady Hollow Homes

- Soffit vents clogged by live-oak and cedar-elm debris. The dense mature canopy that gives Shady Hollow its name deposits decades of organic material into vented soffits. This compresses and moisture-damages original batt insulation at eave perimeters, creating cold bands that show clearly on thermal imaging. We clear soffits and install baffles before blowing any new material.
- Settled original fiberglass at R-11-R-15 effective value. Thirty to forty-five years of gravity and vibration compress blown-in fiberglass to a fraction of its original thickness. Your ceiling assembly performs worse now than the day it was built, and your AC compensates by running longer cycles in 140-160°F attic heat.
- Unsealed top plates and can-light penetrations. 1980s construction didn’t prioritize attic air sealing. Conditioned air leaks continuously through gaps at wall top plates, electrical penetrations, and recessed can lights. Blowing insulation over these leaks is like throwing a blanket over a window fan - the insulation can’t do its job.
- Permit and code complications from previous retrofits. Because Shady Hollow sits in unincorporated Travis County, missing or misapplied permits from past insulation work can trigger code corrections during resale or when topping up. We verify permit history and bring jobs into compliance before adding material.

FAQs - Blown-In Insulation in Shady Hollow

No - Shady Hollow addresses must be verified individually for Austin Energy rebate eligibility because the neighborhood sits in unincorporated Travis County, not within Austin city limits. We check your specific service address during our estimate and will tell you definitively what’s available. Call (254) 970-2136 and we’ll run that verification before you commit to anything.
Austin Energy recommends R-38 to R-60 for Climate Zone 2 attics, and we specify R-49 as our standard target for Shady Hollow homes. Most original blown-in fiberglass in 1980s construction was installed at R-19 or R-30 nominal and has settled to R-11-R-15 effective, so the gap is substantial. Your written scope will state the target R-value and the installed depth required to achieve it.
Only after we inspect what’s there. If the existing material is clean, dry, and uncompressed, we can blow new insulation over it after air sealing. If it’s debris-laden, moisture-damaged, or rodent-contaminated, we remove it first. We never bury problems under new material - that’s not air sealing first, then insulating. We’ll show you photos of what we found and give you a written price for either approach.
Permit requirements in unincorporated Travis County depend on the scope of work and whether previous retrofits were properly permitted. Simple top-ups in attics without structural modification often don’t require permits, but dense-pack wall work and any electrical or HVAC interaction may. We verify permit status during our initial assessment and handle any required applications as part of our scope. Previous unpermitted work can trigger corrections - we’ll flag that before we start.
Yes, particularly dense-pack wall insulation and proper attic air sealing. The February 2021 freeze exposed how poorly insulated pipe cavities and exterior walls perform in Shady Hollow’s older homes. Blown-in insulation reduces conductive heat loss through walls and ceilings, and air sealing prevents the infiltration that pulls cold air into framing cavities. It’s not a guarantee against freeze damage, but it’s the most cost-effective envelope improvement you can make. Call (254) 970-2136 for a free estimate - we’ll assess your specific vulnerability points.
