Owens Corning Blown-In Insulation in Schertz: What to Know First
We provide independent Owens Corning blown-in insulation service in Schertz, typically completing attic jobs in one day with a written price delivered before any work starts. Most blown-in fiberglass or cellulose top-ups in a Schertz home run between $1.80 and $3.20 per square foot of attic floor, depending on existing depth and access conditions. This page is for homeowners who already have Owens Corning insulation in place and need a proper assessment, top-up, or replacement, not a sales pitch for switching brands. Call (830) 402-5240 to schedule a free estimate with a written scope, or bring us a competing quote for our free second opinion.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat PINK Fiberglass Blown-In settling below labeled R-value in Schertz’s heat. The AttiCat system is designed for stable Midwestern climates; in Schertz, where attic temperatures exceed 140°F for months, the fiberglass lofts initially but can settle 10-15% faster than spec in homes with poor ventilation. We measure existing depth with a calibrated depth stick at multiple grid points, calculate the true R-value against current settle, and only then specify the top-up volume needed to hit your target.
- Owens Corning ProCat LooseFill cellulose bridging over irregular joist bays in older Schertz homes. ProCat installs dense at 1.6 lbs/ft³, but in the pre-1980s ranch homes common near Schertz’s Old Town, irregular framing and mixed joist spacing create voids the blower hose misses. Our crew walks every bay during installation, using a 12-inch flexible wand to break bridges and ensure corner-to-corner coverage, then photographs each bay for the Documented Photo Record.
- Owens Corning EcoTouch batt-to-blown transitions creating thermal gaps at attic hatches and kneewalls. EcoTouch batts are common in Schertz’s 1990s-era subdivisions; when homeowners later add blown-in without addressing the batt edges, compression at the perimeter drops the effective R-value by 20-30%. We remove or re-fluff compressed batts at transition zones, install rigid Owens Corning Foamular air barriers at hatch openings, then blow new material to maintain continuous thermal boundary.
- Owens Corning blown-in over unsealed top plates in the Sedona subdivision and similar Schertz builds. We see this weekly: beautiful new PINK insulation sitting atop attic floors where top plate joints, can light housings, and duct boots still leak conditioned air directly outside. The insulation performs as an air filter, not a thermal barrier. Our protocol is blower-door test first, seal every penetration with fire-rated caulk and rigid baffles second, then blow insulation third. Seal the leaks first. Then insulate. The attic doesn’t care how thick the insulation is if the air is still moving through it.
- Owens Corning material contaminated by rodent activity in Schertz’s established neighborhoods near Crescent Ridge. Fiberglass and cellulose both harbor pheromones that attract repeat nesting; simply blowing new material over soiled old insulation creates a recurring problem. We remove contaminated Owens Corning product per Texas Department of State Health Services guidelines, sanitize the substrate, install rodent-proofing at entry points, then replace with fresh material, documenting each phase with photos.
Our Owens Corning Blown-In Insulation Process

- 1
Call and scheduling. A live person answers, 24/7. We book a diagnostic visit in Schertz, typically within 48 hours. You receive a text with your technician’s name when they’re en route.
- 2
Blower-door test and attic inspection. We pressurize the house and measure CFM50 leakage, then inspect the attic with thermal imaging. Wes Okafor and his crew have worked the Schertz corridor for several years; we know which builders skipped top-plate sealing in which subdivisions.
- 3
Written price and scope. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No work starts without it.
- 4
Air sealing first. We seal top plates, electrical penetrations, can lights, and duct boots with appropriate fire-rated materials. This is never an upsell; it’s a prerequisite.
- 5
Blown-in installation. We use Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, or GreenFiber materials matched to your specific job, not proprietary lock-in. Depth is verified with a stick photo log.
- 6
Post-work documentation. Final blower-door reading, printed thermal-imaging summary, depth-stick photo log, and your 365-Day Done Right Promise warranty documents. You leave with evidence, not just a receipt.
What Owens Corning Blown-In Insulation Costs in Schertz

These are real Schertz-market ranges based on jobs we’ve completed in neighborhoods from The Crossvine to Willow Grove. The exact price depends on what we find when we inspect.

Our technicians are background-checked and uniformed. Every job gets a Documented Photo Record. On applicable jobs, you receive before-and-after blower-door numbers showing the actual performance change. The 365-Day Done Right Promise means if it’s not done right, we make it right, backed by a written warranty delivered before work starts. We’ve sealed and insulated over 9,000 homes since 2016, every one with a written price first and documentation at completion.
FAQs
No. Owens Corning product warranties cover manufacturing defects in the material itself, not who installs it. Using an independent service provider does not affect material warranty coverage for defective product. We document batch numbers and install dates so any legitimate claim flows directly to Owens Corning. Call (830) 402-5240 if you have specific warranty paperwork you’d like us to review with you.
We can match Owens Corning AttiCat PINK fiberglass or ProCat cellulose to existing material. New fiberglass will be slightly brighter in color than aged product, but thermal performance depends on depth and density, not color match. For top-ups, we calculate total required depth to achieve your target R-value regardless of existing product age. Call for a free estimate and we’ll specify exactly what goes where.
Topping up is cheaper when existing material is clean, dry, and evenly distributed. Removal and replacement is necessary when material is contaminated, severely settled, or installed over an unsealed attic floor where we’d be adding weight to a problem. During our inspection, we test moisture content and depth uniformity, then give you both options in writing with the price difference clear. Estimates are free.
Most attic top-ups finish in one day. Full removals with air sealing typically take two days. We schedule within 48 hours of your call, and a live person answers the phone 24/7 to book you. Call (830) 402-5240 to check current availability.
We use Owens Corning material when it is the correct specification for the job, and we also source from Johns Manville, Knauf, Rockwool, CertainTeed, and others. We do not use “will-fit” generic blown-in product; every bag is labeled, traceable, and installed to manufacturer density specs. Your written scope specifies the exact material before work starts.
