How Owens Corning Products Fail - and How We Fix Them

Owens Corning makes solid insulation, but Los Angeles attics punish every brand eventually. Heat, rodents, and the occasional roof leak are relentless. Here’s what we see most often in LA homes, and what we do about it.

  • Pink fiberglass batt compression in pre-2000 homes. The classic Owens Corning R-19 and R-30 pink batts lose their loft when homeowners pile storage boxes on top or when LA’s heat cycles break down the binder over 20-plus years. A compressed batt loses a third or more of its R-value. We remove the flattened material and replace it with fresh batts or blown-in fiberglass to the correct depth for your climate zone.
  • Rodent-nested batts in crawl spaces and attics. Owens Corning’s EcoTouch batts are soft enough for rats and mice to hollow out into nesting galleries. We see this weekly in neighborhoods like Van Nuys, Sherman Oaks, and Lake Balboa. Contaminated insulation must be removed, not covered. We vacuum out the old material, sanitize the space, seal entry points, and install fresh insulation.
  • Water-damaged batts from Valley roof leaks. When Owens Corning fiberglass gets saturated from a failed roof boot or a broken tile, it mats down and never recovers its R-value. It also holds moisture against framing, which invites mold. We remove the wet material, treat the affected wood, and replace the insulation only after the roof repair is confirmed dry.
  • Vermiculite and old loose-fill mixed with Owens Corning top-layers. Some LA homes built before 1990 have vermiculite under a newer Owens Corning batt layer. If that vermiculite hasn’t been tested, it’s a liability. We remove both layers carefully, contain the dust, and replace with modern Owens Corning or Rockwool batts that meet current code.
  • DIY batts installed backward or gapped. Kraft-faced Owens Corning batts installed with the paper facing the wrong direction trap moisture. Or they’re cut short around can lights and attic hatches, leaving thermal gaps. We pull the failed installs and redo them properly, including air sealing before the new insulation goes in.

Our Owens Corning Insulation Removal & Replacement Process

Here’s how a typical Owens Corning removal and replacement job goes in Los Angeles, from the first call to the final walkthrough.

  1. 1
    Call and schedule. You reach a live person at (855) 657-3403. We ask about the attic size, access, and what you’ve been seeing, then book a visit that fits your schedule.
  2. 2
    On-site assessment. A background-checked, uniformed technician inspects the attic, checks for moisture, rodent activity, and measures the existing insulation depth. We give you a written quote with upfront pricing before any work starts.
  3. 3
    Containment and removal. We seal off the work area, use commercial HEPA-filtered vacuums for loose-fill and debris, and bag all removed material for proper disposal. No dust drifting into your living space.
  4. 4
    Air sealing and prep. Before new insulation goes in, we seal top plates, can light gaps, and attic hatch openings. This step is where most of the energy savings come from, and it’s often skipped by generalists.
  5. 5
    Replacement install. We install fresh Owens Corning, Rockwool, or CertainTeed insulation to the depth your attic needs for LA’s climate. Most jobs are done in a single visit.
  6. 6
    Final check and guarantee. We walk the attic with you, show photos of the finished work, and confirm the 90-Day Done Right Promise in writing. If it’s not right, we come back and make it right.

Why Los Angeles Homeowners Call Warmline Insulation Co. for Owens Corning Work

We’ve been in business since 2011, and Neil Ashford, our owner, grew up in the San Fernando Valley not far from the Hansen Dam recreation area.
