Owens Corning Insulation Removal & Replacement in Long Beach: What to Know First
We provide independent Owens Corning insulation removal and replacement in Long Beach, typically completing attic jobs in one day with a written price before any work starts. Most Owens Corning removal and replacement projects in this market run between $2,800 and $6,400 depending on attic square footage, contamination level, and whether the existing product is fiberglass batts, blown-in PINK Fiberglas, or the older Thermafiber mineral wool lines. This page is for Long Beach homeowners who have identified Owens Corning insulation in their attic, crawl space, or walls and need it removed safely and replaced with documented performance results. Call (424) 415-7031 for a free estimate with a written scope delivered before we schedule.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning PINK Fiberglas blown-in (ProCat, AttiCat systems) settles below labeled R-value in Long Beach’s marine climate. The salt-laden air and seasonal humidity swings in neighborhoods near Belmont Shore and Alamitos Beach accelerate compression in attics with inadequate ventilation. We remove the settled material, seal top plates and can-light penetrations first, then reinstall to true depth with a depth-stripe verification photo.
- Owens Corning EcoTouch batts degrade when installed over unsealed attic floors in pre-1980s Long Beach housing stock. The kraft facing traps moisture against drywall in bungalows near Bixby Knolls where original soffit ventilation was never upgraded. We remove the contaminated batts, map thermal bypasses with a blower-door test, then replace with new material only after ACH50 targets are met.
- Owens Corning Thermafiber SAFB (Sound Attenuation Fire Battles) in shared-wall applications slumps when wet. We see this in duplexes and fourplexes near downtown Long Beach where roof leaks went unaddressed. Removal requires HEPA containment; replacement demands verifying the wall cavity is dry and sealed before any new fire-rated batt goes in.
- Owens Corning FOAMULAR rigid board in crawl spaces loses adhesion at the perimeter rim joist. The EPS boards separate from framing in the clay-heavy soils of Long Beach’s eastside, where seasonal moisture wicks through foundation walls. We remove the failed boards, treat for mold if present, and re-secure with proper mechanical fastening and sealant compatible with the replacement envelope strategy.
- Owens Corning AttiCat loose-fill installed by previous owners without air sealing creates a filtration layer. Fiberglass becomes a gray mat where conditioned air escapes through ceiling penetrations, especially in homes near the 405 corridor with recessed can lights. We vacuum out the stained material, seal every penetration with fire-rated foam or gasketed covers, then reinstall clean insulation with a verified post-work blower-door reading.
Our Owens Corning Insulation Removal & Replacement Process

- 1
Measure first, then insulate - otherwise you’re just trapping the problem. Wes Okafor or a crew lead arrives with a thermal camera and moisture meter, records existing R-values and depths at five attic locations, and runs a blower-door test if air sealing is in scope. You get a one-page report with these numbers before any quote.
- 2
Written price with scope. Under Haven Standard Clause 1, we deliver a flat price, written scope, and written warranty before anyone schedules. No work starts without it.
- 3
Containment and removal. We establish negative air pressure with HEPA filtration for contaminated jobs, bag Owens Corning fiberglass or mineral wool per local disposal requirements, and photo-document the empty cavity condition.
- 4
Air sealing before replacement. Top plates, wire and pipe penetrations, can lights, and chimney chases are sealed with appropriate materials. We do not blow new insulation over an unsealed attic floor - ever.
- 5
Replacement with verified depth. New Owens Corning, Johns Manville, Knauf, or other specified material is installed to labeled depth with stripe verification. Post-work blower-door numbers are recorded on applicable jobs and delivered with your Documented Photo Record.
- 6
Cleanup and closeout. The crew vacuums the work path, re-installs attic decking if removed, and delivers your written warranty, photo record, and blower-door results before leaving. The 365-Day Done Right Promise applies from this date.

FAQs
No - Owens Corning’s product warranties cover defects in the material itself, not the installation or removal by an independent contractor. The warranty on new Owens Corning insulation products applies when installed to manufacturer specifications, which we document with depth readings and photos. If you have concerns about a specific product line, call us at (424) 415-7031 and we’ll review the warranty terms with your written scope.
Same day in most Long Beach attic jobs, provided the cavity is dry and air sealing is complete. Contaminated removals requiring HEPA containment or crawl spaces with standing water may need 24-48 hours for drying or mold treatment before replacement. We’ll tell you during the estimate visit, not after we’ve started.
Repair is rarely practical for fiberglass or mineral wool products - once compressed, wet, or contaminated, the material cannot be restored to labeled R-value. Replacement is the cost-effective path, especially when paired with air sealing that the original installation skipped. We provide both options in writing if repair is genuinely viable; call (424) 415-7031 for a free estimate.
We maintain standard Owens Corning inventory for common Long Beach attic configurations and source specialty lines within 24-48 hours. We do not use “backorder” as a scheduling excuse - if a material is unavailable, we propose an equivalent from Johns Manville, Knauf, or another named manufacturer with comparable specs, in writing, before you decide.
We measure existing R-values and blower-door performance before work begins, then verify both after installation. You receive a one-page report with pre-install depth readings, post-install depth readings, air-sealing locations addressed, and the blower-door result - a single number showing how much less conditioned air your home loses. No performance claim without the number to back it.
