Owens Corning Blown-In Insulation in Pflugerville: What to Know First
We provide independent Owens Corning blown-in insulation service in Pflugerville, with most attic jobs completed in a single day and pricing put in writing before any work starts. As an independent Owens Corning service provider, we source OEM and quality aftermarket materials directly and carry the full Owens Corning blown-in line, including AttiCat PINK Fiberglass Blown-In Insulation and ProCat Loosefill, alongside Reflectix and other brands for hybrid systems.
This page is for Pflugerville homeowners who already have Owens Corning insulation in place and need top-up, replacement, or correction of a previous install that underperformed. You’ll find actual price ranges below, not a prompt to call for a quote. For a written estimate on your specific attic, call (737) 259-8352.
How Owens Corning Products Fail - and How We Fix Them
- AttiCat PINK Fiberglass settles below labeled R-value in Pflugerville’s high-heat attics. The thermal cycling here, with attic temperatures pushing 140°F through July and August, causes fiberglass loosefill to compact faster than in cooler climates. We see this in homes near Stone Hill Town Center and along Heatherwilde Boulevard where the attic ventilation was marginal to begin with. Our fix: we measure settled depth against the bag chart, calculate the true R-value, then blow additional material to true depth while correcting soffit ventilation blockages that trap heat.
- ProCat Professional Loosefill shows uneven distribution when blown over unsealed top plates. Owens Corning’s ProCat line performs to spec only when the pressure boundary is intact. In Pflugerville’s 1990s-2000s subdivisions, we regularly find top plates and electrical penetrations leaking conditioned air upward, creating thermal bypasses that render even correct insulation depth ineffective. Our fix: we seal every top plate, wire penetration, and can-light housing with fire-rated caulk and rigid foam before the blower truck arrives. The report tells you what the house does. The insulation changes what the house does. Those are two different conversations.
- Owens Corning blown-in over original faced batts creates a double vapor barrier. When previous contractors added AttiCat or ProCat over existing kraft-faced fiberglass batts, the facing becomes a trapped moisture plane. Pflugerville’s spring humidity spikes and occasional winter freeze-thaw cycles make this worse than the dry West Texas climate Owens Corning’s general guidance assumes. Our fix: we remove the original faced batts entirely, air-seal the deck, then install fresh loosefill to a single, uniform layer with no interstitial condensation risk.
- AttiCat installed at insufficient density in wall-slope applications. The AttiCat system is marketed for open attic floors, but Pflugerville’s prevalent 1.5-story and bonus-room designs require dense-pack treatment at kneewalls and sloped ceilings. Standard blown density in these cavities settles and slides. Our fix: we switch to dense-pack methodology for all enclosed slopes, using higher installed density and cavity-by-cavity fill verification, even when the original material spec was standard loosefill.
- Owens Corning insulation compromised by rodent activity in Pflugerville’s established neighborhoods. The greenbelts and creek corridors near Wilbarger Creek and Gilleland Creek feed rodent pressure into older Pflugerville homes. Fiberglass becomes nesting material, and ProCat’s boric acid treatment degrades after saturation. Our fix: we remove contaminated material, sanitize the deck, install metal flashing and hardware cloth at entry points, then blow fresh insulation with a documented photo record of every step.
Our Owens Corning Blown-In Insulation Process

- 1
Scheduled arrival with named technician and text notification. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way. Wes Okafor or a crew lead walks the attic access with you, notes any access limitations, and sets up protective floor covering.
- 2
Blower-door test and attic inspection. We run a pressurization reading that shows, in one number, how much air your building envelope is losing. Most Pflugerville homes built 1995-2010 test between 3,500 and 5,500 CFM50 before work begins.
- 3
Written scope and price before any work starts. Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. We specify Owens Corning material grade, target R-value, air-sealing detail, and cleanup protocol.
- 4
Air sealing first, then insulation. Top plates, can lights, pipe and wire penetrations, chimney chases, and duct boots are sealed with appropriate materials. We never blow insulation over an unsealed attic floor.
- 5
Installation with density verification. AttiCat or ProCat is blown to true depth per manufacturer’s bag chart, adjusted for Pflugerville’s climate zone. We photograph depth markers at multiple locations.
- 6
Post-work blower-door test and documentation. We test again, calculate air leakage reduction, and deliver your Documented Photo Record with before-and-after CFM50 readings, material depth photos, and the written warranty under our 365-Day Done Right Promise.
Before
AfterWhat Owens Corning Blown-In Insulation Costs in Pflugerville
Most attic insulation jobs in a Pflugerville home of 1,800-2,400 square feet run between $1,800 and $3,400 when air sealing and Owens Corning AttiCat or ProCat loosefill are included. Dense-pack wall or slope work adds $800-$1,600 depending on cavity count and access difficulty.
What moves the price: settled material removal, rodent damage repair, accessibility constraints like a 24-inch scuttle hole instead of a full hatch, and whether the home needs baffle installation to protect soffit ventilation. We do not upsell baffles where they are not needed, and we do not skip them where they are.

FAQs
No, adding blown-in insulation does not void Owens Corning’s product warranty, provided the installation follows their published density and depth specifications. We install to those specs and document depth with photos so the warranty record is clean. Call (737) 259-8352 if you need a copy of our installation documentation for your records.
If the existing material is dry, uncompressed, and free of rodent contamination, we can blow additional Owens Corning loosefill on top after air sealing. If we find faced batts underneath, moisture staining, or compressed fiberglass that has lost its loft, we recommend removal and fresh install. We make this determination during inspection and put the reasoning in writing before you decide.
New Owens Corning AttiCat and ProCat will match the pink color of existing fiberglass loosefill, though dye lots vary slightly and new material will sit at full loft while settled old material remains compressed. We do not recommend mixing fiberglass and cellulose, which creates density and moisture-handling mismatches. If your home has a mixed install from a previous contractor, we will note it and recommend correction.
Most jobs are scheduled within 3-5 business days of estimate approval, and standard attic work is completed in one day. Dense-pack wall work or full removal-and-replace projects may run two days. We do not schedule faster than we can execute properly. Call (737) 259-8352 for current availability.
Top-up is cheaper in the short term, typically 40-60% of full replacement cost, but it is only the right choice if the existing material is clean and the air sealing is already complete. In Pflugerville homes where the original install skipped air sealing, topping up wastes money because the new insulation performs at a fraction of its rated R-value. We will show you the blower-door numbers and let you decide with actual data.
