Owens Corning Insulation Removal & Replacement in Los Angeles: What to Know First
We provide independent Owens Corning insulation removal and replacement in Los Angeles, typically completing attic jobs in one to two days with same-week scheduling available. Most Owens Corning retrofits we handle run between $2,800 and $6,500 depending on square footage, contamination level, and whether the attic needs full air sealing before new material goes in. This page is for homeowners who bought or inherited a home with Owens Corning insulation and need it removed safely and replaced with documented performance results. Call (628) 226-1097 for a free written estimate. We answer live, 24/7.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning AttiCat blown-in fiberglass settles below labeled R-value in Los Angeles ceiling assemblies. The loose-fill product, common in 2010-2019 tract builds across the San Fernando Valley, loses 15-25% of its installed thickness within five years due to vibration from LAX flight paths and Santa Ana wind cycles. We vacuum it out, seal top plates and can-light penetrations, then reinstall to true depth with a settled-density calculation.
- Owens Corning PINK Next Gen Fiberglass Batt develops compression gaps around wiring and HVAC runs in older Los Angeles ranch homes. The flexible batt material, designed to friction-fit between 16-inch joists, gets pushed aside by retrofitted electrical in Leimert Park corridor homes where unvented knee walls create hot-side pressure. We remove the displaced batts, install rigid air barriers at knee-wall transitions, then replace with blown-in material that fills irregular cavities.
- Owens Corning Foamular XPS rigid board delaminates in unvented Los Angeles crawl spaces with seasonal moisture spikes. The foil-faced polyiso boards, specified in many 2015-2020 Silver Lake and Echo Park renovations, trap condensation against rim joists during June Gloom cycles. We pull the water-damaged boards, dry the substrate with targeted ventilation, then replace with vapor-permeable assemblies that match the original R-value without repeating the failure.
- Owens Corning EcoTouch batt insulation contaminated by rodent activity in Pasadena and Altadena attic spaces. The formaldehyde-free binder, while safer for indoor air, does not resist gnawing better than competing products. We remove soiled batts with HEPA-contained extraction, sanitize the deck, rodent-proof with galvanized mesh at all penetration points, then reinstall fresh material with a documented photo record of every step.
- Owens Corning ProPink Loosefill L77 shows thermal drift in homes with unsealed soffit chases. The high-coverage product, blown to R-38 spec in many Westside retrofits, gets displaced by wind-washing through bypassed eave vents. We extract the drifted material, install proper baffles and chase dams, then reblow to density with a depth marker photo every fifty square feet.
Our Owens Corning Insulation Removal & Replacement Process

- 1
Call and schedule. A live person answers (628) 226-1097 24/7. We book a site visit, usually within 48 hours in Los Angeles County.
- 2
Blower-door test and attic inspection. Wes Okafor or a trained technician runs a pressurization diagnostic to measure CFM50 leakage before anyone touches the insulation. We photograph existing Owens Corning product labels, depth markers, and any contamination or damage.
- 3
Written price and scope. You get a flat price, written scope, and written warranty before work starts. Haven Standard Clause 1. No exceptions.
- 4
Air sealing first, then removal. We seal top plates, can lights, penetrations, and bypasses. Then we vacuum out the old Owens Corning material with HEPA-contained equipment. Seal the holes first. Then measure the R-value. In that order.
- 5
Replacement and verification. We install new insulation to specified depth and density, run a post-work blower-door test, and provide before-and-after ACH50 numbers, installed R-value documentation, and product data sheets.
- 6
Documented Photo Record delivery. Every photo, every reading, every material spec delivered digitally before the crew leaves. The 365-Day Done Right Promise applies in writing.

Why Los Angeles Homeowners Call Topside Attic Insulation Los Angeles for Owens Corning Work

We are an independent Owens Corning service provider, not a manufacturer-authorized program. That means we source Owens Corning materials when they fit the job, but we also work with Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber if another product solves the problem better. Our technicians are background-checked and uniformed. Calls are answered by a live person, 24/7. Every job gets a written price before work starts and a Documented Photo Record when it ends. On applicable jobs, you receive before-and-after blower-door numbers showing exactly how much air leakage we eliminated. The 365-Day Done Right Promise is in writing, not implied. We have sealed and insulated over 9,000 homes since 2016, every one with the same documentation standard.
FAQs
No. Owens Corning product warranties cover material defects, not installation or removal by independent contractors. If your insulation failed due to a manufacturing defect, we document the product code and install date so you can file a claim directly with Owens Corning while we handle the replacement with new material. Call (628) 226-1097 and we will walk you through the documentation needed.
We source genuine Owens Corning products through standard distribution channels. In some cases, we recommend equivalent or superior materials from other manufacturers, such as Reflectix radiant barriers in specific Los Angeles roof assemblies where Owens Corning does not offer a matching product. We explain the trade-off in writing before you decide.
Replacement is almost always the better value in Los Angeles. Spot-repairing settled AttiCat or displaced batts leaves air leaks unsealed and thermal bridges intact. A full removal and replacement, with proper air sealing, typically pays back in 3-5 years through reduced HVAC load. We will show you both numbers in your written estimate. Call (628) 226-1097 for a free comparison.
Most residential attic jobs finish in one to two days. We schedule within a week of your call, and emergency scheduling is available for contaminated insulation creating indoor air quality issues. Same-week starts are common in the Leimert Park, Silver Lake, and Pasadena areas where our crews are regularly working.
You get a written scope completion checklist, before-and-after blower-door test results in CFM50 and ACH50, installed R-value verification with depth marker photos, product data sheets for all materials used, and a digital Documented Photo Record of the entire process. The 365-Day Done Right Promise warranty is included in writing. This is Haven Standard practice on every job, every time.
