We’ve worked Jollyville’s brick-veneer subdivisions off Spicewood Springs Road, the ranch-style homes near the TX-620 corridor, and the acreage properties backing up to Bull Creek since 2016. Dispatch runs from our Austin office, but our crews live in the north metro and know the difference between a Jollyville attic built to 1982 Williamson County code and one that got upgraded after a remodel permit. That local knowledge matters because Jollyville’s unincorporated status means most homes here never faced the permit-triggered insulation requirements that Austin-addressed properties a mile south absorbed years ago.
Why Topside Attic Insulation Pflugerville Is Jollyville’s Preferred Blown-In Insulation Company
Our reputation in Jollyville was built on one specific practice: we air-seal before we insulate, every time, and we publish the blower-door numbers to prove it. Homeowners here research thoroughly - they read three-star reviews with the same attention they give five-stars - so we don’t ask for trust. We document.
Response time to Jollyville averages same-day or next-day for standard bookings, with emergency calls for post-storm or post-freeze damage prioritized within hours. Our crews carry Owens Corning, Johns Manville, Knauf, and GreenFiber materials on the truck, so we’re not waiting on a supplier run to finish your job.
What separates us in Jollyville specifically is familiarity with the failure modes of 1970s-1990s tract construction. We know where the uninsulated attic water lines run, which can-light housings are fire-rated and which are just old, and how the top plates in these homes leak like sieves until they’re sealed with foam and caulk. That knowledge saves a return trip.

Our Blown-In Insulation Services in Jollyville
Blown-In Cellulose
We use cellulose - ground and fire-retardant-treated recycled paper - on Jollyville homes where the attic deck needs dense coverage and the homeowner wants a material that settles minimally over time. Cellulose runs about $2.00-$2.80 per square foot in this market. It performs well in Jollyville’s summer attic extremes because it doesn’t degrade as quickly as aged fiberglass under sustained 150°F heat. We specify cellulose most often for full removals and replacements, where the original R-19 batts have compressed to uselessness and need to come out entirely.
Blown-In Fiberglass
Fiberglass - spun glass fibers, non-combustible and moisture-resistant - costs slightly more per square foot in Jollyville, typically $2.20-$3.20 installed. We reach for Owens Corning or CertainTeed fiberglass on top-up jobs where the existing insulation is salvageable but thin, or where the homeowner has allergy sensitivities to cellulose dust. In Jollyville’s 1980s two-stories, we often see fiberglass as the right choice for topping over old batts that are still structurally intact but thermally depleted.
Dense-Pack Wall Insulation
Dense-pack means blowing cellulose or fiberglass into closed wall cavities at pressure, packing it to 3.5-4.0 pounds per cubic foot so it won’t settle and leave a void at the top. This is critical in Jollyville’s older tract homes, where exterior walls were often built with no insulation at all or with thin R-11 batts that have collapsed. We dense-pack from the interior through minimal drywall access holes, or from the exterior if siding is being replaced. Typical dense-pack wall jobs in Jollyville run $1,200-$2,400 for a 2,000-square-foot home, depending on cavity depth and access difficulty.
Blown-In Top-Up
The most common call we get in Jollyville. A blown-in top-up adds loose-fill material over existing insulation to reach current R-49 or R-60 targets. But here’s where Jollyville’s specific housing stock changes the job: we almost never recommend a top-up without first air-sealing the attic floor. The original R-19 batts in these homes were installed with no top-plate sealing, no can-light enclosures, and often open chases around plumbing and electrical penetrations. Blow new material over that, and you’ve paid for R-value that the leaks immediately steal. Our top-ups include blower-door-verified air sealing first. Price range: $1,800-$3,600 for a typical Jollyville attic, with the written scope specifying exactly what gets sealed before any insulation goes in.
Our Blown-In Insulation team treats every Jollyville job as a one-trip operation. We stock materials, carry air-sealing supplies, and photograph everything so you have a Documented Photo Record before we leave.

Before
AfterTrusted Brands We Service in Jollyville
We source blown-in materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in, no single-source requirement. For Jollyville jobs, we typically stock Owens Corning fiberglass and GreenFiber cellulose on the truck, with Rockwool and CertainTeed available next-day if your project specifies them. This matters because Jollyville’s acreage lots and detached workshops sometimes call for specific fire-rated or moisture-resistant formulations that aren’t standard stock. We don’t upcharge for brand selection; the written price reflects the material that solves your specific envelope problem.
Common Blown-In Insulation Problems We See in Jollyville Homes
- Compressed original batts performing at half their rated R-value. On a brick-veneer 1980s two-story off Spicewood Springs Road in Jollyville, we opened the attic hatch to find original R-19 batts compressed to roughly half thickness by 35-plus years of 150°F summer attic cycles, with zero air-sealing around top plates or can lights. After air-sealing the attic floor, we dense-packed the sloped wall sections and blew Owens Corning fiberglass over the deck to an R-49 target, then rerouted an uninsulated attic water line that had frozen during Uri so the top-up wouldn’t just get churned by an open chase. The homeowner’s second summer was their first without a 90-degree upstairs bedroom.
- Uninsulated attic water lines re-buried under new material without proper pipe insulation. February 2021 proved that blown cellulose or fiberglass around a copper line isn’t pipe insulation. We still find contractors in Jollyville who bury attic plumbing under new top-ups and call it protected. It isn’t. We specify foam pipe insulation on any line that runs through conditioned-attic space, then blow around it.
- Detached workshops and oversized garages insulated at the door panel but not the perimeter. Jollyville’s acreage lots often have 24-foot or 28-foot shop doors with R-8 panel insulation but 1/2-inch gaps at the jambs and header. The conditioned air bleeds out, the mini-split runs continuously, and the homeowner blames the attic top-up for the energy bill. We air-seal the envelope first, then insulate - even in outbuildings.
- Top-ups blown over unsealed top plates and can-light penetrations. This is the most expensive mistake we correct. The new material looks thick and even, but the blower-door test reads nearly identical to pre-work because the leaks never got sealed. Every top-up we perform in Jollyville includes written air-sealing scope with post-work blower-door verification.

What moves the price: current insulation condition, attic accessibility, whether air sealing is included (it always is with us), and material choice. We don’t quote over the phone without photos or a site visit - but we do provide a Written Price Before Any Work Starts, always, with no obligation until you sign.

Jollyville’s unincorporated-county status creates a specific pricing dynamic: because these homes start from a lower baseline (original R-19, no air-sealing), the upgrade scope is often larger than an Austin-addressed home of identical size. The payoff is also larger. We’ve seen post-work blower-door reductions of 40-60% in Jollyville homes, versus 20-30% in homes that had some prior air-sealing work.

FAQs - Blown-In Insulation in Jollyville
For a 1985 Jollyville home in Central Texas Climate Zone 2, we target R-49 to R-60 on the attic deck, which is what current IECC code specifies and what your HVAC system was likely sized expecting. Most original construction in Jollyville stopped at R-19 or R-22, so you’re looking at roughly doubling the thermal resistance. We specify the exact target R-value in your written scope before work starts, and we verify depth with a probe before we leave. Call (737) 259-8352 for a free estimate with written pricing.
Because Jollyville’s 1970s-1990s tract homes were built with no top-plate sealing, unsealed can-light housings, and open chases around plumbing and electrical penetrations - leaks that can waste 30% or more of your conditioned air regardless of how deep the insulation pile is. We air-seal first, then insulate, because adding R-value over a leaky attic floor is like putting a thicker blanket on a window you left open. Our before-and-after blower-door numbers prove the difference. Call (737) 259-8352 to see actual results from Jollyville jobs we’ve completed.
Blown-in insulation alone will not prevent frozen pipes; it insulates the attic space, not the pipe itself. For Jollyville homes with attic water lines, we specify foam pipe insulation on any exposed copper or PEX, then blow cellulose or fiberglass around the insulated line - never directly against bare pipe. We also identify and seal open chases that allowed Uri’s sub-zero air to pour into wall cavities. The combination of sealed envelope and properly insulated plumbing is what prevented freeze damage in the homes we’ve upgraded since 2021. Call (737) 259-8352 and we’ll map your specific risk points.
Yes. We regularly insulate detached workshops, barns, and oversized garages on Jollyville’s larger lots, often with 24-foot or 28-foot door openings that standard insulation crews won’t touch. The critical step most miss: air-sealing the perimeter gaps at jambs and headers before blowing insulation. We treat outbuildings with the same written scope and blower-door verification as the main house when conditioned air is involved. Call (737) 259-8352 for a written price on your specific building.
We typically specify Owens Corning or CertainTeed fiberglass for Jollyville top-ups where the existing insulation is structurally intact but thermally depleted, because fiberglass doesn’t retain moisture and performs predictably in our 150°F summer attics. We reach for GreenFiber cellulose when we’re doing a full removal and replacement, or when the homeowner prioritizes recycled content and the attic has no active moisture issues. The written scope specifies the exact material and R-value target before anyone starts. Call (737) 259-8352 to discuss which fits your specific attic condition.
