Blown In Fiberglass Insulation in Cedar Park
Blown In Fiberglass Insulation in Cedar Park remains the most common retrofit we install, because it’s fast, effective, and comes in at a lower price point than spray foam. The job involves blowing loose fiberglass fibers across the attic floor to a uniform depth, typically R-38 to R-49 for this climate zone. For a typical 2,000 sq ft Cedar Park home, expect to pay $1.60 to $2.40 per square foot installed, or roughly $3,200 to $4,800 for the full attic including basic air sealing around penetrations.
When Fiberglass Makes Sense
Fiberglass blown-in works best in wide-open vented attics with decent access, which describes most 1990s-2010s tract homes in Cedar Park. The material settles slightly over the first year, so we over-blow to compensate and hit your target R-value after settlement. Fiberglass doesn’t absorb moisture the way cellulose can, which matters in central Texas attics where summer humidity spikes and roof deck temperatures climb past 140°F. If your attic already has some batts but they’ve sagged, we can either remove them or blow over the top depending on condition.
For Cedar Park homes with shallow roof pitches, blown fiberglass gets into the tight triangle where eaves meet the top plate far better than any batt ever will. That’s where heat sneaks in around the perimeter.
Loose Fill Insulation in Cedar Park
Loose Fill Insulation in Cedar Park often refers to blown cellulose, and it’s the material we recommend most frequently for older tract homes with settled fiberglass batts. The job involves blowing dense-packed or loose cellulose, usually GreenFiber or Knauf products, across the attic floor and into sidewalls where needed. Cost runs $1.40 to $2.10 per square foot for attic floor application, with whole-home retrofit projects in Cedar Park landing between $3,000 and $5,800 depending on square footage and prep work.
Why Cellulose Outperforms in Old Attics
Cellulose packs tighter than fiberglass, which means it resists air movement through the insulation itself. In a Cedar Park attic where the original R-30 batts have slumped to R-19, blowing a fresh R-38 layer of cellulose over the top seals the thermal gaps and restores real performance. The material also settles less over time when installed at proper density, and it fills odd cavities, around trusses, over duct chases, into the corners of hip roofs, that batt insulation never touches.
We stock GreenFiber, Knauf, and Johns Manville loose fill locally, so a Cedar Park job doesn’t wait on a warehouse shipment from Dallas.
Trusted Brands We Service in Cedar Park
We don’t push one brand on every home. We match the product to the problem. For loose fill cellulose in an older Cedar Park attic, we usually reach for GreenFiber or Knauf. For blown fiberglass, Owens Corning and Johns Manville sit on our trucks day to day. Each of these eight brands we carry, including Rockwool and CertainTeed, serves a specific purpose, and we stock enough depth locally that a Cedar Park retrofit doesn’t stall out waiting on materials. Your tech carries what the job needs, not whatever happened to be in the warehouse that week.
Common Blown In Insulation Problems We See in Cedar Park Homes
- Settled builder-grade fiberglass batts: Homes built in the 1990s and 2000s around Cedar Park often got R-30 batts that now measure R-19 or less. That 30% loss in thermal resistance translates directly to hotter upstairs rooms and higher July electric bills.
- Undersized or blocked soffit vents: Many Cedar Park tract homes have soffit vents that are painted over, crushed by blown-in insulation from a prior owner’s DIY job, or simply too few for the attic volume. Trapped heat and moisture then cause new insulation to mat down and lose loft within a few summers.
- Bypasses around recessed lights and bath fans: We regularly find can lights, exhaust fans, and duct chases with no air sealing at all. Hot attic air pours around these gaps and bypasses whatever insulation sits on the attic floor. Upstairs rooms stay hot no matter how much new material goes in.
- Two-story thermal stacking: The open foyer and bonus room designs common in Buttercup Creek and Ranch at Brushy Creek create a chimney effect. Hot air rises through the house, superheats the upstairs ceiling, and the attic insulation takes the hit. If the upstairs runs 10 – 15°F hotter than downstairs in July, the diagnostic points to attic insulation, not your AC.
Last month we were out in the Ranch at Brushy Creek area where the homeowner’s upstairs bedroom was running 14°F hotter than the downstairs despite the AC running nonstop. Our tech found the original fiberglass batts had settled to R-17 and were leaving the ceiling joists exposed. We air-sealed the attic floor and blew in a full R-38 layer of GreenFiber cellulose across the whole attic, including the detached workshop above the garage. Done in one trip with our heavy-duty hose rig, so the homeowner could get back to his normal routine by dinnertime.
Pricing for Blown In Insulation in Cedar Park, TX
Here are real numbers for this market, not vague estimates. Attic floor blow-in over existing insulation runs $1.40 to $1.80 per square foot in Cedar Park. Full removal of old, settled batts plus new blown-in material runs $2.20 to $2.80 per square foot. A 2,000 sq ft home at the mid-range lands around $3,200 to $5,600. Detached workshops and oversized garages add square footage but usually come in at the lower end per foot because they’re simpler spaces. The variables that actually move your price: how much old material needs removal, how much air sealing is required around penetrations, and whether we’re adding radiant barrier or ventilation upgrades at the same time.

FAQs About Blown In Insulation in Cedar Park
A 10 – 15°F temperature difference between your upstairs and downstairs rooms in the afternoon, combined with visible settling or bare ceiling joists in the attic, signals the original insulation has failed and needs air sealing plus a full blow-in, not just more material dumped on top. If the upstairs runs hot even when the AC cycles normally, call (325) 246-2929 for a free assessment.
Yes, we blow insulation into detached workshops, garages, and bonus rooms above garages across Cedar Park regularly. These unconditioned spaces heat up fast in a Texas summer, and a proper R-38 layer in the attic above makes a workshop usable year-round. Our one-trip rig handles detached structures without needing a second visit.
Only if ventilation isn’t addressed at the same time. We check soffit and ridge vent airflow before adding insulation, and we upgrade ventilation where it’s undersized. A properly ventilated attic with R-38 or better insulation actually performs better in Cedar Park’s humid summers, because the insulation keeps conditioned air in the living space and out of the hot attic cavity.
Properly installed blown-in fiberglass or cellulose in Cedar Park attics holds its R-value for 20 to 30 years, provided the attic stays dry and ventilation works. Builder-grade batts, by contrast, often fail within a decade. If you’re seeing settling or temperature splits in a home built before 2015, call us for a free attic inspection and a written quote.
Yes, blown-in material fills the tight eave spaces and irregular cavities of shallow-pitch roofs far better than batts ever can. Cedar Park’s tract homes with 4/12 and 5/12 pitches leave narrow gaps at the perimeter that batts can’t seal. Loose fill flows into those spaces and blocks the heat path completely. To see if your attic qualifies, call (325) 246-2929.
If your Cedar Park attic is under-insulated, settled, or turning your upstairs into a hotbox every summer, call us at (325) 246-2929.
