Owens Corning Blown-In Insulation in Glendale: What to Know First
We provide independent Owens Corning blown-in insulation service throughout Glendale, and most jobs are done same-day or next-day, from assessment to final cleanup. A typical blown-in top-up or full attic install runs $1,100 to $2,800 in Glendale depending on square footage and the existing insulation’s condition, and dense-pack wall work starts around $2,400 for a standard exterior wall. That’s honest pricing with a free estimate before any work begins.
This page is for Glendale homeowners who already have Owens Corning insulation, or are considering it, and want a straight answer about how it holds up, what fails, and what it costs to make it right. We’re an independent Owens Corning service provider, not a factory-authorized dealer, which means we make recommendations based on what’s actually best for your house, not a brand mandate. Call (747) 246-7237 and a live person answers, day or night.
How Owens Corning Products Fail - and How We Fix Them
Owens Corning makes solid insulation products, but nothing lasts forever in a Glendale attic, where summer temps routinely push past 140 degrees at the roof deck. Here’s what we actually see when we get called out.
- AttiCat Fiberglass settling and loss of R-value. Owens Corning’s AttiCat blown-in fiberglass is a good product, but after 10 to 15 years in a Glendale attic it compresses from its own weight and from foot traffic during HVAC or electrical work. We measure the settled depth, calculate the actual remaining R-value, and top up to the DOE-recommended R-38 for this climate zone, which usually means adding 8 to 12 inches.
- ProPink blown-in fiberglass matting at the eaves. In older Glendale homes we frequently find the original ProPink or AttiCat fiberglass has matted down near the soffit vents, where moist air from bath fans and kitchen exhaust condenses. The matted fiberglass blocks airflow and loses insulation value. We remove the matted material, verify soffit ventilation is working, and re-blow the area without blocking the airflow path.
- Cellulose settling around recessed lights and chimneys. Some Glendale homes built in the 1960s through 1980s got Owens Corning cellulose blown in around non-IC-rated can lights and masonry chimneys. That’s a fire-code problem waiting to happen. We install proper barriers, pull the cellulose back to safe clearances, and rebuild the thermal boundary the right way.
- Missing coverage behind knee walls in Spanish-style Glendale homes. The Spanish and Mediterranean-style houses up in the Verdugo foothills have knee walls and sloped ceiling cavities that original installers often skipped. We use Owens Corning’s dense-pack technique for enclosed cavities and a blown-in application for open attic floor sections, so the whole envelope performs together.
- Blown-in top-up over failed original batts. A lot of Glendale attics have 1960s Owens Corning fiberglass batts that have sagged out of the rafter bays. Loose-fill blown over the top is a band-aid; the thermal break remains. We remove or reposition the failed batts first, then blow to full depth, so you’re not paying for insulation that’s just covering up a problem.
Our Owens Corning Blown-In Insulation Process
Every Owens Corning blown-in job in Glendale follows the same steps, whether it’s a top-up in a 1,200-square-foot bungalow in Moorpark or a full attic in a Verdugo Woodlands two-story.
- 1
Free on-site assessment. We come to your Glendale home, measure the attic, check existing R-value, inspect ventilation, and look for air leaks. No trip charge inside the county, and you get an honest recommendation even if the answer is “your insulation is fine.”
- 2
Air sealing first. Blown-in insulation can’t do its job if conditioned air is leaking through top plates, recessed lights, and plumbing penetrations. We seal those openings before we blow a single bag.
- 3
Material selection. We’re brand-agnostic, so we’ll recommend Owens Corning AttiCat fiberglass when it fits the job, or Johns Manville, Knauf, CertainTeed, or GreenFiber cellulose when a different material makes more sense for your specific attic.
- 4
The install. Our background-checked, uniformed crew blows to the target depth, checks density with a gauge, and works around all the obstacles properly: chimneys, can lights, vents, and access hatches.
- 5
Final verification. We show you the depth readings, confirm the coverage is even, and walk the attic with you if you want to see it yourself.
- 6
Done Right Promise. Every job is covered by our lifetime workmanship guarantee. If it’s not done right, we make it right. No runaround, no “call back during business hours.”
What Owens Corning Blown-In Insulation Costs in Glendale
Here’s what we quote in Glendale, and these are real numbers from jobs we’ve done in the past year. Everything includes labor, materials, and cleanup.
- Attic top-up over existing insulation: $1,100 to $1,600 for a typical 1,200 to 1,500 sq ft Glendale home
- Full attic blown-in, including air sealing: $1,800 to $2,800, depending on attic size and accessibility
- Dense-pack wall insulation: $2,400 to $4,500 for a standard single-story exterior wall set
- Insulation removal and re-blow: $2,200 to $3,800 when old material has to come out first (rodent damage, moisture, or fire-code issues)
What moves the price: attic accessibility, whether air sealing is needed, the condition of the existing insulation, and whether we’re doing removal or just a top-up. Seniors and veterans always get 10% off, and you’ll get an exact quote before we start. Call (747) 246-7237 for a free estimate.

FAQs
Owens Corning AttiCat and ProPink blown-in products carry the manufacturer’s limited warranty for the material itself, but our workmanship is covered for life under the Done Right Promise. If our install is ever wrong, we fix it, period. Call (747) 246-7237 with your warranty questions and we’ll give you a straight answer about what’s covered and what’s not.
Yes, we match both material type and existing R-value coverage, so a top-up blends seamlessly with your current Owens Corning insulation rather than mismatching fiberglass over cellulose or vice versa.

Removal and replacement runs roughly twice the cost of a top-up, so we only recommend it when it’s genuinely necessary. Call (747) 246-7237 and we’ll tell you which route is right for your attic, free.
