Owens Corning Blown-In Insulation Nationwide

Owens Corning Blown-In Insulation in Tustin: What to Know First

We provide independent Owens Corning blown-in insulation service in Tustin, typically scheduling within 48 hours and completing most attic jobs in a single day. Most Tustin homes we see need R-38 blown fiberglass or cellulose in the attic, with wall dense-packing where the original batts have settled. You’ll get a written price before anyone lifts a tool, and we don’t start work until you’ve seen it.

How Owens Corning Products Fail - and How We Fix Them

• Owens Corning AttiCat PINK Fiberglass Blown-In settling below labeled R-value. The AttiCat system uses loose-fill fiberglass that can lose 10-15% of its settled depth in the first three years, especially in Tustin’s warm-dry climate where thermal cycling is aggressive. We measure existing depth with a ruled probe, calculate current R-value against the bag label, and blow to compensate - typically 16.5 inches for R-38 - so the homeowner hits code even after future settling.
• Owens Corning ProCat loose-fill developing thermal bypass around recessed cans and top plates. ProCat installs fast, but the material itself doesn’t stop air movement. In a 2019 Tustin Legacy build we tested last March, the blower-door read 3,800 CFM50 with ProCat in place - the insulation was fine, the air leaks were the problem. We pull back the existing fill, seal penetrations with fire-rated caulk and rigid baffles, then reblow. Post-sealing reading: 2,100 CFM50.
• Owens Corning EcoTouch batts compressed by homeowners storing holiday decorations. EcoTouch PINK batts lose R-value permanently when squashed. We find this in about one of every four Tustin attics we enter. Our fix: remove the damaged section, air-seal the floor beneath it, and blow loose-fill to restore uniform coverage without creating future storage temptation.
• Owens Corning blown-in fiberglass migrating away from eaves due to wind-washing. Tustin gets Santa Ana events that pressurize attic vents. Without proper baffling, PINK fiberglass drifts toward the ridge and leaves bare spots at the eaves. We install cardboard or foam baffles at every soffit vent before blowing, then spot-check with a thermal imager before we close up.
• Owens Corning systems installed before 2016 missing California Title 24 compliance documentation. Pre-2016 attics in Tustin often have R-19 or R-30 where R-38 is now required for replacement permits. We photograph existing conditions, note the Owens Corning product line if identifiable, and provide a written R-value report with thermal images that satisfies permit inspectors and future buyers.

Our Owens Corning Blown-In Insulation Process

1. 1
   Call and scheduling. A live person answers. We book a 2-hour arrival window, send a text when the technician is en route, and name the technician you’ll meet.
2. 2
   Attic inspection and blower-door test. We probe existing insulation depth, identify the Owens Corning product line if present, and run a blower-door test - pressurizing the house to 50 pascals to measure air leakage in CFM50. This number goes on your report.
3. 3
   Air sealing before insulation. Seal the leaks first. Then insulate. The R-value on the bag means nothing if conditioned air is moving through the gap around that recessed can. We seal top plates, can lights, plumbing penetrations, and chimney chases with fire-rated materials.
4. 4
   Material selection and written price. We specify Owens Corning AttiCat, ProCat, or a compatible aftermarket loose-fill depending on your attic conditions and budget. You get a flat price, written scope, and written warranty before anyone starts - Haven Standard Clause 1.
5. 5
   Installation and verification. We blow to depth, verify with a ruled probe, and run a post-installation blower-door test on applicable jobs. The before-and-after numbers go on your documented record.
6. 6
   Cleanup and documentation. You receive a Documented Photo Record, thermal images, the written R-value report, and our 365-Day Done Right Promise in writing. We haul away old material if removal was in scope.

What Owens Corning Blown-In Insulation Costs in Tustin

Most attic top-up jobs in Tustin run $1.80 to $2.40 per square foot for Owens Corning blown fiberglass to R-38, with full removal and replacement at $3.50 to $4.80 per square foot. Dense-pack wall work runs higher - typically $2.80 to $4.20 per square foot of wall area - because of the access labor.

What moves the price: attic square footage, existing material condition, accessibility (vaulted ceilings add labor), and whether we find rodent damage requiring cleaning before blowing. We also service Reflectix radiant barrier systems where supplemental insulation is needed. Call (657) 286-7673 for an exact quote - estimates are free, and we offer a Free Second Opinion on any written estimate you’ve already received.

Why Tustin Homeowners Call Topside Attic Insulation Tustin for Owens Corning Work

We’ve sealed and insulated over 9,000 homes since 2016, and a growing share of them are in Tustin Legacy where the post-redevelopment housing stock put blower-door testing on the map as a baseline step. Wes Okafor and our crew know the Owens Corning product lines from hands-on work, not from a distributor brochure - we can tell AttiCat from ProCat by the fiber diameter and binder smell, and we know which Tustin attics have the wind-washing problem before we climb the ladder.

Every job closes with a Documented Photo Record and, on applicable work, before-and-after blower-door numbers you can hand to an HVAC contractor or future buyer. The 365-Day Done Right Promise applies to all completed work. Materials come from Owens Corning, Johns Manville, Knauf, and other manufacturers - no proprietary lock-in, so we specify what fits your house rather than what moves our inventory.
