How Knauf Products Fail - and How We Fix Them
Knauf makes solid insulation, but Pomona’s specific conditions push every product to its limits. Here’s what we see in the field, what it means for your home, and how we handle each one.
- Knauf EcoBatt (fiberglass batts) with rodent contamination. In Pomona neighborhoods like Westmont and Phillips Ranch, rats and mice tunnel through batt insulation, leaving urine, droppings, and shredded fibers. Batts compress and lose R-value, and the smell travels through the house. We remove every contaminated batt, sanitize the attic deck, seal entry points, and install fresh batts or blown-in. Rodent-soiled Knauf can’t be cleaned, it has to go.
- Knauf Jet Stream blown-in fiberglass settling. Jet Stream is common in Pomona homes built or reinsulated in the 2000s. Over time, especially in attics that hit 140°F during Pomona summers, the loose-fill compacts. You lose up to 20% of your R-value. We extract it with a commercial vacuum rig, air-seal the attic floor, and blow in new material to the correct depth for Southern California’s climate zone.
- Knauf R-13 and R-19 kraft-faced batts with moisture damage. When bathroom fans vent into the attic, which we see regularly in older Pomona ranch homes, kraft facing traps moisture against the drywall. The result is mold staining, sagging batts, and gypsum damage. We remove the affected Knauf, correct the venting, replace any compromised drywall, and install unfaced batts or blown-in with proper airflow.
- Knauf EcoRoll in walls with failed air barriers. EcoRoll batts are fine products, but they were never designed to stop air movement. In Pomona’s older bungalows, especially around Ganesha Park where homes predate modern building codes, walls with only EcoRoll leak air constantly. We remove wall insulation when needed during renovations, air-seal stud bays, and reinstall with a higher-density product or spray foam.
- Vermiculite-lookalike situations. Some Pomona homes from the 1950s and 60s have loose-fill that homeowners assume is old Knauf. It’s not always. If we find material we can’t identify by sight, we test before touching it. Knauf never made vermiculite, but knowing the difference matters for safety and disposal. As an independent contractor, we follow California hazmat protocols when materials are suspect, and we’ll tell you plainly what we found.
Our Knauf Insulation Removal & Replacement Process
Here’s how a typical Knauf job goes from first call to final walkthrough:
- 1
Call and schedule. A real person answers at (626) 341-0830 and books your free estimate. We ask about your home’s age, what’s in the attic now, and any symptoms you’ve noticed like drafts, smells, or high bills.
- 2
On-site inspection. A background-checked, uniformed tech shows up in a marked van. We inspect the attic, crawl space, and walls as needed. We check Knauf’s condition, measure depth, test for moisture, and look for pest activity.
- 3
Your options, in plain language. We tell you exactly what we found and what it’ll cost to fix. No pressure, no scare tactics. Neil Ashford trains every tech to say “this doesn’t need doing” when that’s the honest answer.
- 4
Removal day. We run HEPA-filtered commercial vacuums, bag everything on site, and haul it out through your home with floor protection in place. Most Knauf removal jobs are done the same day.
- 5
Prep, air seal, and replacement. Before any new material goes in, we air-seal penetrations, check venting, and confirm no pest entry points remain. Then we install your replacement: Knauf again, Owens Corning, Rockwool, CertainTeed, or GreenFiber, depending on your goals and budget.
- 6
Final walkthrough and the 90-Day Done Right Promise. We show you the finished space, verify your numbers, and hand you the written guarantee. If it’s not done right, we make it right.
What Knauf Insulation Removal & Replacement Costs in Pomona
Here’s what Pomona homeowners can expect to pay for common Knauf removal scenarios. These are real ranges, not teaser prices. Your quote depends on attic size, access difficulty, contamination level, and what you’re putting back in.
| Job Type | Typical Range in Pomona | What’s Included |
|---|---|---|
| Basic Knauf batt removal, 1,200 sq ft attic | $1,800 - $2,800 | Removal, bagging, haul-off, basic disposal |
| Blown-in Knauf Jet Stream removal, 1,200 sq ft | $2,200 - $3,600 | Vacuum extraction, bagging, haul-off |
| Full removal + air sealing + new blown-in fiberglass | $4,800 - $7,500 | Removal, air sealing, new R-38 blown-in |
| Removal + spray foam replacement (attic floor) | $6,000 - $9,500 | Removal, prep, closed-cell or open-cell spray foam |
| Contamination surcharge (rodent or mold) | Add $500 - $1,500 | Sanitizing, PPE, specialty disposal |
What moves the price: attic accessibility (crawl spaces with low clearance cost more), contamination severity, and whether you’re replacing with fiberglass (lower material cost) or spray foam (higher, but far better air sealing). The $50 Off Any Repair Over $250 and 5% Senior & Veteran discounts apply here too. Call (626) 341-0830 for an exact quote. Estimates are free, and they’re line-itemed so you see exactly what you’re paying for.

FAQs
Yes, in most cases. A standard 1,200 square foot Knauf attic removal takes 4 to 6 hours, and we schedule removal and replacement as a single visit whenever possible. Call (626) 341-0830 in the morning and we can often have a crew out the same day or next.
Only if your time is worth nothing and you already own a commercial vacuum system. Knauf removal means renting equipment, buying contractor bags, hauling material to a disposal site that accepts insulation, and spending hours in a 140-degree Pomona attic. Homeowners who try it usually call us halfway through. Our pricing is upfront, and you’ll get the job done in half the time with none of the cleanup. The honest assessment from Neil Ashford: this is one job where the professional route usually costs less in the end once you factor in equipment rental, disposal fees, and your own labor.
Knauf insulation warranties cover manufacturing defects in the product itself, not installation. Removing old Knauf doesn’t affect a warranty because the warranty applies to the material, not your home. And if you’re replacing with new Knauf, the new material carries its own warranty from the manufacturer. We install to spec so any applicable warranty stays valid.
Depends on your attic and your goals. For most Pomona homes, we recommend blown-in fiberglass to R-38 or higher. For attics with air-sealing needs, spray foam from Icynene or Demilec outperforms batts. We carry Knauf, Owens Corning, Rockwool, CertainTeed, Johns Manville, and GreenFiber, and we’ll show you the cost and performance difference for each option before you decide.
Yes. Knauf batts are common in Pomona crawl spaces, and they fail fast when moisture gets involved. We remove soggy or rodent-damaged batts, address the moisture source, and reinstall with a product suited to below-grade conditions, or we move you to full crawl space encapsulation if that’s the better long-term fix.
