This page is for Pasadena homeowners who have Knauf insulation in their attic, walls, or crawl space and need it removed due to age, contamination, moisture damage, or rodent activity. If you’re researching whether to repair or replace, what Knauf-specific issues to watch for, or what documentation you should receive from any contractor you hire, the details below are drawn from our work in Pasadena attics since 2016.
How Knauf Products Fail - and How We Fix Them
- Knauf EcoBatt settled below labeled R-value in Pasadena’s dry heat. The fiberglass batts compress and shift in attics that cycle above 140°F in July, especially in older Pasadena homes near Bungalow Heaven with minimal roof ventilation. We remove the compressed batts, air seal the attic floor, then replace with new material at full labeled thickness.
- Knauf Jet Stream Ultra blown-in fiberglass stratifies in long-run attics. In the deep, rectangular attics common along Orange Grove Boulevard, the blown material separates by density, leaving thin spots near the eaves. We vacuum out the stratified insulation, verify soffit vent baffles, and reinstall with even distribution confirmed by depth markers every 300 square feet.
- Knauf Insulation with ECOSE Technology holds moisture after roof leaks. The plant-based binder in ECOSE-series batts degrades when wet, creating a musty odor and reduced loft that standard fiberglass wouldn’t show. We remove the affected sections, treat the deck with an antimicrobial, and replace only after moisture readings drop below 15%.
- Knauf Attic Access Insulation gets disturbed by HVAC contractors and never replaced properly. We find this constantly in Pasadena’s 1950s-1970s ranch homes where the original access panel insulation, a Knauf rigid board product, gets tossed aside during ductwork and stuffed back loosely. We replace with a proper insulated access hatch and weatherstrip seal.
- Knauf blow-in blanket system (BIBS) collapses in walls with plumbing leaks. The netting and fiberglass combination in BIBS walls traps water against studs in Pasadena’s occasional heavy winter rains, particularly in additions with flat roofs. We cut selective access, remove the wet system, dry the cavity, and reinstall with a vapor-smart assembly.
Our Knauf Insulation Removal & Replacement Process
- 1
Call and scope. A live person answers (213) 816-5351 24/7. We schedule a site visit, and Wes Okafor or a senior tech arrives with a written price promise, no exceptions.
- 2
Attic assessment with documentation. We photograph existing Knauf product condition, measure settled depth against labeled R-value, and run a blower-door test, a pressurization reading that shows, in one number, how much air your building envelope is losing.
- 3
Air sealing before any new insulation. We seal top plates, can lights, and penetrations. Seal the leaks first. Then insulate. The numbers will tell you why.
- 4
Removal with HEPA containment. Knauf fiberglass is vacuumed into sealed bags, not dragged through your living space. Contaminated material gets manifest-tracked disposal.
- 5
Replacement with verified performance. New Knauf or equivalent material installed to labeled depth, with post-job blower-door numbers and thermal images in your customer folder.
- 6
Written closeout. You receive the written warranty, the photo record, and the before-and-after numbers before we leave. Haven Standard: Have it in writing.

Price moves with attic accessibility (truss spacing, ductwork density), contamination level requiring PPE upgrades, and whether the original Knauf product was installed over unsealed bypasses that must now be addressed. We also service Reflectix and other brands if your project involves mixed materials. Every estimate is free, written, and includes a Free Second Opinion on any competing written quote you bring us.
Why Pasadena Homeowners Call Topside Attic Insulation Pasadena for Knauf Work
We’re independently owned and operated under The Haven Standard since 2016, not a franchise, and we don’t push proprietary products. Our techs know Knauf’s full line from EcoBatt to Jet Stream Ultra to BIBS because we’ve removed and replaced all of them in Pasadena’s specific housing stock, the Craftsmans with knee-wall attics, the midcentury ranches with shallow trusses, the Spanish Revival additions with flat roofs that pool moisture.
Every job gets the 365-Day Done Right Promise, background-checked uniformed technicians, and a text when your tech is en route. The before-and-after blower-door numbers are published on every applicable job, not available on request. And the written price, scope, and warranty arrive before anyone lifts a tool. Haven Standard Clause 1.
FAQs
Knauf’s product warranty covers manufacturing defects, not installation or removal by an independent contractor. As an independent Knauf service provider, we document the original product condition with photos before removal so any legitimate defect claim can still be filed. If you’re concerned about warranty preservation, call (213) 816-5351 and we’ll review what’s documented in your customer folder.
Most residential attic jobs finish in one to two days. Contaminated removals add a day for sanitizing and drying verification. We schedule to minimize disruption, and you’ll get a named technician with a text when they’re on the way. For a specific timeline on your home, call (213) 816-5351 for a free written estimate.
Adding over old insulation is cheaper upfront but usually costs more over time. In Pasadena’s climate, old compressed Knauf product reduces the effective R-value of new material above it, and it traps moisture and rodent debris against the attic deck. We remove and start clean so the new insulation performs at its labeled value, and the blower-door numbers prove the difference. Call for a written price on both approaches.
We source Knauf, Owens Corning, Johns Manville, Rockwool, CertainTeed, and others, no proprietary lock-in. If you want matching Knauf product for aesthetic or warranty continuity, we can specify it. If another material performs better for your specific Pasadena attic conditions, we’ll document why in the written scope before you decide.
We typically schedule within three to five business days for standard jobs, sooner for active moisture or rodent contamination that affects indoor air quality. A live person answers (213) 816-5351 24/7 to check current availability and get your written estimate started.
