This page is for GreenFiber owners specifically. Whether your GreenFiber cellulose has settled in the attic or you’re weighing a dense-pack wall job, we’ll tell you what your house actually needs, not what runs up a bigger invoice.

How GreenFiber Products Fail - and How We Fix Them

• SANCTUARY cellulose settling and compaction in attics. GreenFiber SANCTUARY is a high-density cellulose, but over 10 to 15 years, even good installation settles in Pasadena’s dry heat, especially along the thermal bypass points near can lights and bathroom fans. R-value drops from R-38 to the low R-20s in spots. We map the attic, identify the settled zones, and blow a measured top-up layer to restore even coverage without overloading the ceiling drywall.
• Moisture wicking in older GreenFiber Cocoon installations. We still find Cocoon-era cellulose in mid-century Pasadena homes near Eaton Canyon and the Arroyo, where humidity pushes up through crawl spaces. Cellulose holds moisture, and once it wicks, it slumps and loses insulating power. We pull the wet material, air-seal the source, and reinstall with proper ventilation in place. Skipping the air seal is how you end up redoing this job in three years.
• Dense-pack wall settling and thermal voids. GreenFiber’s dense-pack wall insulation can settle slightly over decades if the original installer blew at inconsistent pressure. That leaves a cold band near the top plates, which you’ll feel as a persistent draft along exterior walls in winter. We drill and re-dense the voided bays from inside or outside, depending on your siding, and patch cleanly.
• Rodent and pest damage through compromised GreenFiber batts. GreenFiber also makes batt products, and when rodents work through them in Pasadena attics, the resulting tunnels create heat-loss corridors. Rodent proofing is part of our core work. We remove the damaged sections, seal entry points, and re-blow the area so the insulation performs the way it was spec’d.
• Inconsistent coverage from a previous contractor’s rush job. More often than we’d like, we inspect a “finished” GreenFiber blow and find 4 inches in one corner and 14 in another. That’s not a product failure, that’s an installer failure, and it shows up in hot, stuffy rooms in mid-afternoon Pasadena heat. We re-blow to spec and document the depth with photos so you can see what you paid for.

Our GreenFiber Blown-In Insulation Process

Here’s what a real GreenFiber job looks like when you call Walt’s Insulation.

1. 1
   Call and talk to a person. (626) 606-2964. A live person answers, every time, 24/7. You describe what’s going on: cold room, high bill, or a finished attic that just never felt right.
2. 2
   On-site inspection and measurement. We come to your Pasadena home, inspect the attic or walls, measure existing depth, check for moisture, rodent activity, and air leaks. We’ll show you photos of what we find.
3. 3
   Straightforward quote. You get a written number for the exact work, including depth targets and material specs. No vague language. We also offer a free second opinion on any written estimate you’ve already received.
4. 4
   Prep and air sealing where needed. Before we blow GreenFiber, we seal the thermal bypasses. In Pasadena homes, this is where the real energy loss happens: top plates, wire penetrations, can light housings, and flue gaps.
5. 5
   The blow. We install GreenFiber cellulose or fiberglass to spec, working with the brand you already have or topping up with a compatible product for even coverage and correct density.
6. 6
   Cleanup and documentation. We leave the attic cleaner than we found it, show you before and after photos, and explain exactly what was done. Then it’s covered by our lifetime Done Right Promise, because if it’s not done right, we make it right.

What GreenFiber Blown-In Insulation Costs in Pasadena

Attic top-ups in Pasadena, depending on your home’s square footage and existing depth, typically run between $1,400 and $2,800 for a full GreenFiber re-blow to R-38 or higher. Dense-pack wall insulation for a standard 1,200 to 1,600 square foot single-story runs roughly $3,200 to $5,500, with older Pasadena bungalows often landing on the higher end thanks to plaster and lath. Local factors move the price too: access difficulty in tight attics, existing rodent damage, and whether we’re pulling old insulation first. The single biggest cost driver is whether air sealing is needed, which it usually is in Pasadena homes built before 1980.

We price the job upfront with no surprises. Call (626) 606-2964 for a free estimate, and ask about our standing offers: $40 off any repair over $200, and 10% off for seniors and veterans, always.
