This page is for GreenFiber owners in Glendale who suspect their insulation isn’t performing like it should. Whether you’ve got GreenFiber cellulose in the attic, GreenFiber blown-in fiberglass in the walls, or GreenFiber Sanctu-Fiber in a retrofit, we know how these products behave in Southern California’s dry heat and what to look for when they start to underperform. We’re an independent GreenFiber service provider, not a manufacturer rep, so we tell you what’s actually going on, not what GreenFiber’s marketing department wants you to hear.

How GreenFiber Products Fail - and How We Fix Them

GreenFiber makes solid insulation products, but every material has weak points. Here’s what we find in Glendale homes during energy audits:

• GreenFiber cellulose settling in attics. Cellulose settles over time, and in Glendale’s dry climate, it can lose R-value faster than in humid regions. We regularly find attics in the Verdugo Woodlands and Rossmoyne neighborhoods where 12 inches of GreenFiber cellulose has compacted to 7 or 8. The fix is a top-up blow, and we always verify depth after with a ruler, not a guess.
• GreenFiber Sanctu-Fiber coverage gaps in wall cavities. Sanctu-Fiber is a dense-pack product, and when it’s installed too fast or without proper pressure, you get voids behind outlet boxes and around window framing. During a thermal imaging sweep, these show up as bright blue cold spots along exterior walls. We drill, probe, and fill the gaps, then re-scan to confirm.
• GreenFiber fiberglass batts installed backward in crawl spaces. This one’s common in older Glendale homes near the 2 freeway where DIY work happened before a sale. The kraft paper facing ends up facing the crawl space instead of the living space, trapping moisture. During an audit, we catch this with a simple visual inspection and fix it by flipping or replacing the batts.
• Dust infiltration from cellulose settling around can lights. In Glendale’s older bungalow stock, GreenFiber cellulose around recessed fixtures breaks down into fine dust that drifts into living areas. Homeowners notice more dust on furniture in summer. We address this with insulation dams and air sealing around the fixtures.
• GreenFiber blown-in fiberglass losing coverage after roof work. When roofers or solar installers work in an attic, they push insulation aside and never put it back. We’ve seen Glendale attics with GreenFiber fiberglass shoved into a corner leaving entire sections of ceiling bare. An audit finds it, we rake it back into place and top up.

Our GreenFiber Home Energy Audit Process

Here’s how a GreenFiber audit goes when you call Walt’s Insulation:

1. 1
   You call (747) 246-7237. A real person answers, day or night. We ask about your home, when the insulation was installed, and what you’re noticing: high bills, hot rooms, drafts, dust.
2. 2
   We schedule the audit and show up in a marked truck. Background-checked, uniformed technicians. No surprises at the door.
3. 3
   We run the blower door test. This depressurizes the house and shows us exactly where air is leaking. For GreenFiber homes, this tells us if the insulation itself is the problem or if air sealing is the bigger fish.
4. 4
   We walk the house with a thermal camera. Walls, ceilings, floors, around windows and outlets. We’re looking for voids, settling, moisture, and thermal bridging that GreenFiber products are prone to in Glendale’s climate.
5. 5
   We inspect accessible cavities. Attic, crawl space, rim joists. We measure depth, check coverage, and look for the failure modes above, plus rodent damage and moisture intrusion.
6. 6
   We hand you a written report with photos and a fix list. If repairs are needed, we quote them upfront. If your GreenFiber insulation is fine, we tell you that too. Then you decide what’s worth doing, and we back any work with the Done Right Promise.
