This page is for Glendale homeowners who found GreenFiber loose-fill cellulose in their attic, suspect it’s underperforming or contaminated, and want a contractor who will test the building envelope before touching the insulation. We are not affiliated with or authorized by GreenFiber. We are an independent service provider.

How GreenFiber Products Fail - and How We Fix Them

• GreenFiber All Borate loose-fill settling below labeled R-value. In Glendale’s dry-summer climate, cellulose that was blown to R-38 in 2018 often reads R-28 or lower by year five due to vibration from nearby Burbank Airport flight paths and seasonal thermal cycling. We remove the settled material, air-seal the attic floor at top plates and can-light penetrations, then reinstall to true depth with a settled-density calculation.
• GreenFiber Sanctuary blown-in wool blend retaining moisture near roof sheathing. The Sanctuary line’s natural fiber content can wick humidity from bathroom vents that terminate in attics, a code violation we find in roughly 30% of Glendale homes built 1955-1975. We extract the damp batts or loose fill, treat the sheathing with an antimicrobial if staining is present, relocate the vent to exterior, and replace with a borate-treated cellulose or synthetic alternative.
• GreenFiber stabilized cellulose with failed boron treatment attracting rodents. When the borate fire retardant leaches out in attics with active roof leaks, the cellulose becomes palatable to roof rats common in the Verdugo Woodlands and Chevy Chase Canyon areas. We remove the contaminated insulation under negative air pressure, seal entry points with galvanized steel mesh, and reinstall with fresh borate-treated material.
• GreenFiber dense-pack wall insulation slumping in balloon-frame construction. Homes near Glenoaks Boulevard and the 134 corridor often have no top plates, meaning dense-pack cellulose in stud bays can settle into the wall cavity below. We extract through interior or exterior access points, install blocking at the balloon-frame transition, and re-dense-pack with a two-stage fill that locks in place.
• GreenFiber installed over unsealed recessed can lights creating thermal bypasses. Pre-2016 GreenFiber installs in Glendale rarely included airtight can-light enclosures. The insulation performs as installed, but conditioned air streams past it through the fixture housings. We remove insulation in the affected zones, install fire-rated LED retrofit housings or Tenmat covers, then reinstall insulation to full depth. Seal the bypasses first. Insulation over air leaks is just expensive noise reduction.

Our GreenFiber Insulation Removal & Replacement Process

1. 1
   Call and scheduling. A live person answers, or you text. We schedule a site visit with a named technician. Under Haven Standard: Arrive on schedule, you get a named technician and a text when they are on the way.
2. 2
   Blower-door test and attic inspection. We run a blower-door test - a pressurization measurement that shows, in one number, how much air your building envelope is losing - before a single bag is opened. We photograph the existing GreenFiber, note depth, condition, and any contamination. You receive the pre-work photos and CFM50 reading in writing.
3. 3
   Written price and scope. We deliver a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. No work starts without it.
4. 4
   Removal and air sealing. We extract the GreenFiber under negative air pressure, HEPA-filter the attic air, and seal all penetrations, top plates, and bypasses. This is never optional.
5. 5
   Replacement and verification. We install replacement insulation to specified depth, run a post-work blower-door test, and provide printed pre- and post-installation ACH50 numbers side by side. You also receive a Documented Photo Record of the completed work.
6. 6
   365-Day Done Right Promise. If it’s not done right, we make it right. Backed by the written scope you already have.

Why Glendale Homeowners Call Topside Attic Insulation Glendale for GreenFiber Work

We’ve been running jobs across Glendale since 2016, including older ranch-style homes near the Verdugo Woodlands where dense-pack cellulose in balloon-frame walls is still the right call once the blocking is fixed. Wes Okafor learned the trade at Richard J. Daley College, where the curriculum was heavy on air sealing before it was fashionable anywhere, and our crew still runs a blower-door test before opening the first bag.

We are not locked into GreenFiber or any single brand. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber - we specify what performs for your assembly, not what moves our inventory. We also service Reflectix and other radiant barrier systems when the roof deck configuration calls for it. Every job closes with a Documented Photo Record and, on applicable work, printed blower-door numbers. Calls are answered by a live person, 24/7.
