How Owens Corning Products Fail – and How We Fix Them

Owens Corning makes solid insulation, but no product survives every Los Angeles summer without some attention. Here’s what we actually see in attics across the city:

• AttiCat Pink Fiberglas settling below R-value. Owens Corning’s AttiCat blown-in fiberglass is rated to maintain its R-value, but after years of thermal cycling in Los Angeles attics, we regularly find it compacted to 60-70% of its original depth. That turns an R-30 attic into an R-19 attic, and your cooling bills show it. We remove the settled material, assess whether the attic ventilation contributed to the problem, and re-blow to the correct depth with density checks every 100 square feet.
• ProPink L77 moisture absorption at soffit lines. Along rooflines where soffit vents don’t flow properly, Owens Corning ProPink L77 can wick moisture during coastal June gloom and marine layer mornings, especially in Westside and South Bay neighborhoods. The fiberglass itself doesn’t rot, but damp insulation loses R-value and invites mold into the decking. We identify the ventilation failure first, fix the airflow, then replace the affected insulation. Blaming the insulation without fixing the airflow is how you get the same problem twice.
• Gaps around can lights and bath fans after original installs. A lot of Los Angeles homes got Owens Corning blown in years ago without proper baffling around recessed lights and exhaust fans. The insulation gets pushed back, creating bare spots. Or worse, it sits too close to non-IC-rated fixtures creating a fire hazard. We build proper dams around fixtures, seal air leaks at the fan housings, and re-blow to full depth. This is one of the most common fixes we do, and a lot of homeowners don’t even know the gaps exist until we run a thermal scan.
• AttiCat machine rental jobs done wrong. We love that Owens Corning sells AttiCat to DIY homeowners through home centers, but a rental blower in the wrong hands leads to wildly inconsistent density. Some areas get over-blown, some get almost nothing, and the depth markers vanish. We’ve walked attics where the homeowner paid good money for bags of AttiCat and ended up with worse coverage than what they tore out. We re-blow the entire attic to uniform density, and we do not charge you extra to haul out the failed attempt.
• Owens Corning blown in over old, failed insulation. In pre-1980 Los Angeles homes, we often find Owens Corning blown in layered directly over old rock wool or cellulose that’s been holding moisture for years. The new insulation looks fine on top, but the whole assembly is underperforming and possibly growing mold. Our process in those attics is full extraction to the deck, air sealing, then fresh Owens Corning blown in at proper depth. You cannot fix a rotten base by throwing more material on top of it.

Our Owens Corning Blown In Insulation Process

Here’s exactly how a blown in insulation job goes when you call Aspen Attic Insulation Los Angeles:

1. 1
   Call and talk to a person. You call (213) 376-3824. No phone tree, no call-back window. We ask what’s going on, what you’re feeling in the house, and when you’re available. We schedule a walkthrough.
2. 2
   Meet your tech by name and photo before they arrive. Before the visit, we send you the technician’s name, photo, and what they’ll be doing. When they show up, they’re in a clean marked uniform and they show you a photo ID badge at the door. If anyone other than that named tech arrives, the visit is free and we make it right. That’s the Threshold Standard, and it is not optional.
3. 3
   Attic inspection with real numbers. Your tech goes into the attic, measures existing insulation depth in multiple spots, checks for air leaks, looks at ventilation, and documents what they find with photos. You get a written report with the actual R-value you currently have versus what’s appropriate for Los Angeles.
4. 4
   Written price before any work. We hand you a written price that covers materials, labor, disposal, and any sealing or baffling that needs to happen. That price does not change after the job starts. No post-job surprises, ever.
5. 5
   The blow, done right. We use calibrated blowers, depth markers every 12 feet, and density checks throughout the job. Owens Corning material goes in at the R-value we quoted, wall to wall, with fixtures baffled and soffits protected.
6. 6
   Final check and your written guarantee. We walk the attic with you or show you photos from the job, confirm the R-value achieved, and clean up everything. You get your 365-Day Done Right Promise in writing covering labor and materials. If it’s not right within a year, we come back and fix it free.

What Owens Corning Blown In Insulation Costs in Los Angeles

Here’s what we typically see across Los Angeles for Owens Corning blown in work. These are real ranges based on the jobs we do, not national averages that don’t apply to this market:

What moves the price: access (low-pitch roofs and tight attics take longer), existing insulation condition, whether we’re hauling out old material, and how much air sealing your attic needs. Los Angeles climate matters here. If your attic hits 140°F in August, we may recommend a higher R-value than the national minimums suggest.
