How Owens Corning Products Fail - and How We Fix Them

• AttiCat Pink Fiberglass settling in older Pasadena attics. Owens Corning’s AttiCat blown-in fiberglass works well when installed to spec, but homes built before the 1990s in neighborhoods like Bungalow Heaven often had far less than code. We regularly find R-19 settled to R-11 after twenty years of Pasadena’s summer heat cycling. Our fix: air-seal the attic floor, then top up to R-38 or R-49 depending on your roofline.
• ProPink blown-in fiberglass showing thermal drift in vaulted ceilings. Vaulted and cathedral ceilings common in mid-century Altadena builds let loose-fill fiberglass shift over time, especially where there’s no proper baffling. You get cold spots along the slope. We remove the old fill, install baffles, and dense-pack the cavity so it stays put.
• Dense-pack cellulose settling around recessed lights. When Owens Corning cellulose was blown into walls or sloped ceilings around older can lights, heat from the fixtures accelerates settling. We see this a lot in Pasadena homes with original 1970s lighting. We address the clearance issue first, then re-blow at the correct density.
• Moisture-compromised fiberglass along Pasadena’s older roof valleys. Pasadena’s winter rains find their way into attic spaces through worn valley flashing, and fiberglass loses R-value fast when it gets damp. Owens Corning fiberglass doesn’t wick moisture like cellulose, but it also doesn’t dry easily once soaked. We find the leak, fix the flashing or recommend a roofer, and only then replace the insulation.
• Undersized initial installs from big-box subcontracted crews. We’ve walked into homes where the previous company blew AttiCat to “R-38” but missed entire bays over the garage. That’s not an Owens Corning product failure - it’s an install failure. We measure with a depth gauge before we quote anything, so you know what’s actually up there.

Our Owens Corning Blown-In Insulation Process

1. 1
   Call and talk to a real person. We answer the phone live, every hour. You tell us what’s happening: high utility bills, hot rooms, drafts. We schedule a visit with no trip charge inside the county.
2. 2
   We measure what’s actually there. Walt’s crew checks existing depth, bay coverage, air leaks, and moisture. If you have a written estimate from another company, bring it - we’ll give a free second opinion.
3. 3
   We give you a straight quote. Upfront pricing based on square footage, target R-value, and whether you need air sealing first. No vague “we’ll see how it goes.”
4. 4
   We prep the space. Air sealing comes first when needed. Then we set up containment, run the hose, and blow to spec at the correct density for Owens Corning fiberglass or cellulose.
5. 5
   We verify and clean up. Depth checks in multiple spots, not just by the hatch. Full cleanup. You walk the space with us before we leave.
6. 6
   Done Right Promise. If it’s not done right, we make it right - for the life of the work. That’s not a one-year tagline. It’s our guarantee.

Why Pasadena Homeowners Call Walt’s Insulation for Owens Corning Work

We’re the one down the road. Walt’s Insulation has been locally owned and owner-operated since 2000, with a published address and license number - not a franchise, not a call center. Walt Brenner grew up in San Antonio, where summers teach you fast what bad insulation feels like, and he’s been straight with homeowners since day one. Our techs are background-checked and uniformed, and they know Owens Corning products well enough to tell you when a top-up will do the job versus when you’d be better off with a different brand. We also work with Rockwool, Johns Manville, Knauf, CertainTeed, Icynene, Demilec, GreenFiber, and Reflectix - so we’re not married to any one product line. We answer the phone live because your house doesn’t keep business hours - and neither do we.
