Why Topside Attic Insulation Cedar Park Is Georgetown’s Preferred Blown-In Insulation Company
We’ve sealed and insulated over 9,000 homes since 2016, and a significant share of those have been in Georgetown’s two dominant housing eras: the aging Sun City Texas developments and the newer master-planned communities that exploded after 2010. Our crews know the difference between a late-1990s Del Webb slab home on Sun City Boulevard and a 2018 build off Shell Road, and we adjust our approach accordingly.
Georgetown homeowners leave reviews that mention the same things repeatedly: the blower-door numbers we publish, the photo record they receive, and the fact that we answered the phone at 8 PM on a Sunday. Our 365-Day Done Right Promise applies to every job in Georgetown, backed by a written scope and warranty delivered before anyone lifts a tool.
Response time to Georgetown averages same-day or next-day scheduling, with crews carrying Johns Manville and Knauf materials stocked for common cavity depths found in local homes. We don’t route through Dallas or Houston; our Austin office dispatches directly to Georgetown addresses.
Our Blown-In Insulation Services in Georgetown
Blown-In Fiberglass
We blow Owens Corning and Knauf fiberglass in Georgetown attics where the existing insulation has degraded but the cavity remains accessible. Fiberglass doesn’t absorb moisture the way cellulose can, which matters in Georgetown’s warm-humid Climate Zone 3A where attic humidity spikes during spring storms. In Sun City homes with 25-year-old original R-30 that’s settled to R-11 or below, we often remove the compacted layer and blow fresh fiberglass to R-49 or R-60, depending on truss height. Our Blown-In Insulation team documents the before-and-after depth with photos you receive at job completion.
Blown-In Cellulose
Cellulose works well in Georgetown’s flat attics where dense packing is possible and fire-retardant treatment is specified. We source from GreenFiber and treat the material with borate for pest resistance, which matters in areas near the San Gabriel River where roof rats and squirrels are active. Cellulose settles less than older formulations, but we still account for 10-15% loss over the first two years when calculating initial depth. We don’t blow cellulose over unsealed top plates or can lights; that’s Haven Standard Clause 1, and it’s non-negotiable.
Dense-Pack Wall Insulation
The historic wood-frame homes near Georgetown’s downtown square, built from the 1880s through the 1920s, typically have no wall insulation at all. Dense-packing cellulose or fiberglass into closed cavities from the exterior requires drilling access holes, blowing to 3.5-4.0 pounds per cubic foot, and patching with matching siding. We’ve done this on homes along Main Street and in the Olive Street historic district. For Sun City’s slab-on-grade brick veneers, dense-pack isn’t typically needed in walls, but vaulted cathedral ceilings are a different story.
Blown-In Top-Up
This is our most common service call in Georgetown. Original blown-in insulation in Sun City Texas homes from the late 1990s through the 2010s has settled after 25-plus years of 140°F+ thermal cycling. We find R-11 where R-30 was originally installed. A top-up blows additional material over the existing layer after air sealing is complete, bringing the assembly to current IECC code for Zone 3A. We measure existing depth with a ruled probe, photograph every bay, and give you the numbers before we start. Top-ups in Georgetown typically run $1,800-$3,400 for homes under 2,500 square feet.

Common Blown-In Insulation Problems We See in Georgetown Homes
- Settled R-30 in Sun City’s aging slab homes. Original blown-in fiberglass or cellulose installed from the late 1990s through the 2010s has compacted to R-11-R-15 after decades of thermal cycling. The attic looks full until you probe it; then you find 4-6 inches where 12 inches once sat.
- Vaulted cathedral ceilings at R-8 or less. In Sun City Texas, the living room ceilings that soar to the roofline were often insulated with faced batts that have sagged away from the deck, or with minimal blown-in that never filled the cavity. The HVAC runs continuously because the roof deck radiates 140°F heat directly into the room below.
- Post-2010 builder-minimum over unsealed leaks. Master-planned subdivisions off Shell Road, University Avenue, and FM 1460 received code-minimum blown-in installed over top plates, recessed can lights, and plumbing penetrations that were never sealed. The insulation is present but bypassed; conditioned air leaks into the attic all summer.
- February 2021 storm damage to HVAC and pipes. Winter Storm Uri exposed how poorly insulated Georgetown attics protect equipment when temperatures drop to single digits. We’ve replaced insulation in dozens of attics where frozen condensate lines or cracked air handlers traced directly to inadequate R-value and missing air sealing.
Pricing for Blown-In Insulation in Georgetown, TX
Most blown-in insulation jobs in Georgetown fall within these ranges:
| Service | Typical Range |
|---|---|
| Blown-In Top-Up (flat attic, under 2,500 sq ft) | $1,800 - $3,400 |

| Air Sealing + Blown-In (complete package) | $3,200 - $6,500 |
What moves the number: cavity depth and accessibility, whether existing insulation must be removed first, the extent of air sealing required, and whether we’re dealing with a standard flat attic or a complex vaulted section. Sun City homes with multiple cathedral ceilings and settled original insulation typically land in the upper half of these ranges. We provide a written price before any work starts, always, and offer a Free Second Opinion on any competing written estimate. Every job includes a Documented Photo Record and, on applicable work, before-and-after blower-door readings.

FAQs - Blown-In Insulation in Georgetown
Your vaulted cathedral ceiling was likely insulated to R-8 or less by the original builder, or the faced batts have sagged away from the roof deck after 20-plus years of heat cycling. We dense-pack these cavities with blown-in fiberglass to R-38, which creates a continuous thermal barrier between your living space and the 140-150°F roof deck. Call (737) 245-6428 and we’ll probe the cavity depth and give you a written price.
We consistently find R-11 to R-15 where R-30 was originally installed, a 50-60% loss in thermal performance after 25 years of thermal cycling. The material hasn’t disappeared; it has compacted and degraded, leaving your attic far below IECC Zone 3A’s R-38 minimum. A blown-in top-up after air sealing restores performance without full removal. We measure with a ruled probe and show you the photos.
Uri exposed that most pre-2015 Georgetown attics couldn’t protect pipes or HVAC equipment during extended single-digit temperatures. The event drove local code enforcement toward stricter air-sealing requirements and higher R-values for replacement work. We now see more homeowners opting for R-49 to R-60 and comprehensive top-plate sealing, not just for summer cooling loads but for winter resilience. Your blower-door test quantifies the improvement.
Flat attics get loose-fill fiberglass to R-49 or R-60; vaulted cathedral sections get dense-pack fiberglass to R-38, which requires higher density to prevent settling in the sloped cavity. We don’t use the same material or technique for both. The flat attic is vented and accessible; the vaulted section is a sealed assembly that demands different handling. Our crew specifies the approach in your written scope before work begins.
Yes, particularly if the home received builder-minimum blown-in over unsealed top plates and can lights. The insulation is present but thermally bypassed; conditioned air leaks into the attic through gaps the blower-door test will reveal. We’ve worked in subdivisions off Shell Road and FM 1460 where post-2010 homes tested at 3,500+ CFM50 before sealing and dropped below 2,000 after. The insulation was code-compliant on paper; the air leakage wasn’t. Call (737) 245-6428 for a Free Second Opinion on your home’s current performance.
