Owens Corning Blown-In Insulation in Cedar Park: What to Know First
We provide independent Owens Corning blown-in insulation service in Cedar Park, typically completing attic retrofits in one day with a written price locked before any work starts. Most Owens Corning top-up or full-replacement jobs in this market run between $1,800 and $4,200 depending on attic square footage and whether the existing fiberglass has settled below the joists. This page is for homeowners who already have Owens Corning insulation in their Cedar Park home and need to know whether to add more, replace what’s there, or pair it with air sealing first. Call (737) 245-6428 and a live person will answer, 24/7.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning ProPink L77 loose-fill fiberglass settles below R-38 in Cedar Park attics within 8-12 years. The 140°F summer attic temperatures in neighborhoods like Buttercup Creek accelerate compression, and homeowners notice the second floor won’t cool below 78°F even with the AC running flat out. We measure current depth against the labeled bag coverage, calculate the shortfall, and blow new ProPink to the correct settled depth, not the initial fluff height.
- Owens Corning AttiCat system installations often skip the top-plate sealing step, because the big-box rental program trains users to blow, not to seal. Conditioned air pumps out through gaps at the wall top plates, so the new R-value performs like old R-19. We run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing - seal every top plate and penetration with fire-rated caulk and foam, then blow.
- Owens Corning EcoTouch batts, when removed for dense-pack wall retrofits, leave voids at electrical boxes and plumbing chases. The kraft facing tears, and installers rarely patch the gaps. Our crew photographs every cavity before dense-packing, then fills with Owens Corning ProPink L77 or, for fire-rated assemblies, Rockwool AFB. You get the photo record with your invoice.
- Owens Corning blown-in jobs done over unsealed can lights create a direct path for attic air into living space. The IC-rated housings still leak 2-4 CFM50 each at the trim ring, and in Cedar Park’s clay-heavy soils, that pressure differential pulls humid crawl space air upstairs. We install sealed LED retrofits or Tenmat covers before any insulation goes near the fixture.
- Owens Corning ProPink blown over old cellulose creates a stratified layer that traps moisture at the interface. Cedar Park’s spring humidity spikes hit 85% RH, and the cellulose wicks while the fiberglass stays dry on top. We remove the cellulose if it’s below 3 inches, air seal the deck, then blow ProPink to a uniform depth with no transition zone.
Our Owens Corning Blown-In Insulation Process
- 1
Call and schedule. A live person answers at (737) 245-6428, 24/7. We book a 2-hour arrival window and text you when the technician is en route.
- 2
Pre-install blower-door test and attic inspection. We measure ACH50 - air changes per hour at 50 Pascals pressure - and photograph existing Owens Corning depth, condition, and any settled areas. Wes Okafor, our owner, trained on blower-door diagnostics at Olive-Harvey College in Chicago, and we don’t skip this step.
- 3
Written price and scope. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1: no work starts without it.
- 4
Air sealing first. Top plates, can lights, plumbing penetrations, and chimney chases get sealed with fire-rated materials. Seal the leaks first. Then insulate. The order matters more than the product.
- 5
Blown-in installation to labeled coverage. We use Owens Corning ProPink L77 for attics, or dense-pack L77 for open wall cavities, calculating bags by the manufacturer’s settled-depth chart, not guesswork.
- 6
Post-test, photo record, and documentation. We run the blower-door again, hand you the before-and-after ACH50 numbers, and deliver your Documented Photo Record before the crew leaves.

FAQs
No, adding insulation to manufacturer specifications does not void any product warranty, but improper installation - like covering soffit vents or non-IC-rated fixtures - can create coverage disputes with your builder or roofer. We photograph every vent and fixture before covering anything, and that photo record goes in your file. Call (737) 245-6428 if you want us to review your home’s specific warranty terms before we start.
Top up if the existing fiberglass is dry, uncompressed below the joists, and free of rodent contamination; remove and replace if it’s water-stained, compacted from foot traffic, or mixed with older cellulose that creates moisture traps. We test with a moisture meter and visual inspection, then give you both options in writing. Call (737) 245-6428 for a free inspection and written comparison.
Most attic top-ups happen within 3-5 business days of your call; full removals with air sealing typically schedule within 7-10 days. We don’t overbook, and we don’t cancel to chase bigger jobs. Call (737) 245-6428 to check this week’s availability.
We use Owens Corning ProPink L77 loose-fill fiberglass for blown applications, sourced through authorized distributors - but we are an independent Owens Corning service provider, not a factory-authorized dealer. For air-sealing accessories like Tenmat covers or fire-rated foam, we use quality third-party products that meet or exceed OEM specs. We don’t lock you into proprietary materials; if Rockwool or Johns Manville better fits your fire-rating or moisture requirements, we’ll say so in writing.
We hand you a printed before-and-after blower-door report with ACH50 numbers - the pressure-to-airflow figure that tells you exactly how leaky the envelope was. A typical Cedar Park retrofit drops from 4,500 ACH50 to 2,200 ACH50 or better after sealing and insulating. You don’t have to trust our word; you hold the number. Call (737) 245-6428 to schedule your test.
