GreenFiber insulation removal and replacement in Pomona typically takes one full day for most single-story attics, and we complete the majority of jobs in a single visit. As an independent GreenFiber service provider, Warmline Insulation Co. removes settled, damp, pest-damaged, or contaminated cellulose insulation and replaces it with fresh GreenFiber blown-in product, matched to your home’s existing depth and R-value needs.

This page is for Pomona homeowners who bought a house with GreenFiber insulation already installed, or who had it blown in years ago and now wonder if it’s doing its job. If your attic feels swampy in August, your cooling bills keep climbing, or you’ve spotted rodent activity up there, the insulation is often the first thing that needs to go. Call (626) 341-0830 and a live person answers, 24/7. No voicemail, no phone tree.

How GreenFiber Products Fail - and How We Fix Them

GreenFiber makes a solid cellulose product. We install it regularly. But no insulation lasts forever, especially in Pomona’s climate, where attic temperatures routinely hit 140°F in July and August and winter brings damp marine air. Here’s what we actually see on GreenFiber removal jobs in Pomona homes:

• Settling and density loss in GreenFiber SANCTUARY. Cellulose settles naturally over the first few years. In Pomona attics with poor ventilation, we’ve measured 10 to 14 inches of GreenFiber SANCTUARY settled down to 5 or 6 inches. That cuts the R-value roughly in half. The fix is removal of the settled material and a fresh blow to the depth your ceiling joists actually call for.
• Moisture wicking in older GreenFiber Cocoon applications. GreenFiber Cocoon was marketed for wall cavities. In Pomona homes near the 10 and 57 freeways where drainage is poor, we’ve pulled Cocoon out of walls that wicked moisture from a small plumbing leak or stucco crack and held it against the framing for years. Cellulose doesn’t shed water like foam does. We remove it, dry the cavity, and only then do we reinsulate.
• Rodent tunneling in any blown GreenFiber attic. Rats and mice love cellulose. Pomona’s older neighborhoods, especially around Ganesha Park and Lincoln Park, have mature trees and older sewers, which means rodent pressure is real. Once animals tunnel through GreenFiber, the material is contaminated with droppings and urine. Removal, sanitizing, and rodent proofing have to happen before new insulation goes in. This is one of the most common GreenFiber removal jobs we do in Pomona.
• Fire-retardant degradation over decades. GreenFiber treats cellulose with borate-based fire retardants. Those treatments don’t last forever. In a 30-year-old attic, we’ve tested material that barely smolders when it should resist flame. That’s a safety issue, not just a comfort issue. If your Pomona home’s GreenFiber predates the Clinton administration, it’s time for removal and replacement.
• Dust and particulate release from disturbed GreenFiber. Older GreenFiber breaks down into fine particles. When a homeowner or a pest company disturbs it, that dust ends up in the living space through ceiling penetrations. We remove it with commercial HEPA-filtered vacuums, not a shop vac and a prayer. The difference matters when you have kids or anyone with asthma in the house.

Our GreenFiber Insulation Removal & Replacement Process

Every GreenFiber job in Pomona follows the same disciplined sequence. No shortcuts, no surprises.

1. 1
   Call and diagnosis. You reach a live person at (626) 341-0830. We ask about your home’s age, the rooms that feel hot or cold, and any pest or moisture issues you’ve noticed. If a home energy audit makes sense, we schedule it first so the removal doesn’t happen blind.
2. 2
   Attic inspection. Our background-checked, uniformed technician documents the existing GreenFiber depth, checks for moisture, rodent activity, and framing condition. You get photos and a straight assessment. If the insulation doesn’t actually need to come out, we’ll tell you. Neil Ashford has walked away from jobs that weren’t worth doing, and he’ll do it again.
3. 3
   Removal. We use commercial-grade HEPA vacuums and sealed containment to pull out the old GreenFiber without dusting out your whole house. Rodent-contaminated material goes into sealed bags and off your property the same day.
4. 4
   Prep and air sealing. Before new insulation goes in, we seal ceiling penetrations, top plates, and any gaps that let conditioned air leak into the attic. Insulation without air sealing is half a job.
5. 5
   Fresh GreenFiber installation. We blow in new GreenFiber to the depth that matches your climate zone and energy goals. Most jobs are completed in a single visit.
6. 6
   Test and guarantee. We verify depth and coverage, show you the results, and back the work with our 90-Day Done Right Promise. If it’s not done right, we make it right. Written, not verbal.
