This page is for Anaheim homeowners whose Knauf insulation has been through it: rat droppings in the blown-in fiberglass, urine-soaked batts, tunnels chewed through the R-38, or that smell that creeps into the hallway when the attic heats up. If that sounds like your house, call (657) 214-8224 and a live person answers. Walt Brenner started this company in 2000, and we’ve been cleaning up Knauf attics across Anaheim long enough to know exactly what we’re walking into.

How Knauf Products Fail - and How We Fix Them

• Knauf EcoBatt fiberglass batts hold rodent urine like a sponge. The kraft paper facing wicks moisture, and once rats nest in it, the batt delaminates from the drywall. We see this constantly in older Anaheim ranch houses with original Knauf insulation from the 90s. You can’t spot-clean it. We pull the contaminated batts, sanitize the deck, and blow in fresh Knauf or Owens Corning at the correct R-value for Orange County’s climate zone.
• Knauf Jet Stream blown-in fiberglass compresses into rodent runways. Rats don’t just walk on top of blown-in insulation, they tunnel through it. The material gets matted down to a fraction of its original depth, and suddenly your attic is effectively R-11 instead of R-30. After exclusion, we re-fluff where possible and top off with fresh blown-in so the thermal barrier actually does its job again.
• Kraft-faced Knauf batts give rodents a ready-made nesting material. That brown paper facing? Rats shred it. They strip it off the batt, drag it into corners, and build nests. Homeowners sometimes find shredded kraft paper inside duct boots and wall cavities. Our fix includes sealing entry points first so new nesting material stops arriving, then removing the damaged batts and refitting with unfaced product or a properly installed air barrier.
• Knauf R-38 in unconditioned Anaheim attics traps heat and amplifies odor. When rodents die inside thick insulation, the Anaheim summer heat bakes the odor into everything. A 110-degree attic turns a dead rat into a house-wide smell problem within hours. We locate and remove carcasses during cleanout, then use an antimicrobial fogger on surfaces where odor compounds have soaked in, not just a masking spray.
• Knauf’s paper-backed insulation makes rodent damage harder to spot from the hatch. Because the kraft paper covers the fiberglass, homeowners peeking into the attic see what looks like intact insulation. The damage is underneath. That’s why we do a full walk-through with photos during the inspection so you see exactly what we’re seeing before you spend a dime.

Our Knauf Attic Cleaning & Rodent Proofing Process

1. 1
   Call and talk to a person. You reach a live voice at (657) 214-8224, day or night. We ask about the house, the symptoms, and schedule a walk-through. No trip charge inside the service county.
2. 2
   Full attic inspection with photos. We get into the attic, check the Knauf insulation’s condition, map rodent entry points along the roofline, soffits, and gable vents, and document everything. You get the photos, not just our word.
3. 3
   Upfront quote, no vague ranges. We give you a written number for cleanout, sanitizing, exclusion, and any insulation replacement. You decide what’s in and what’s out. We don’t push work you don’t need.
4. 4
   Containment and removal. We lay down floor protection, use HEPA-filtered vacuums to pull contaminated Knauf fiberglass and debris, and bag everything for disposal. No insulation dust drifting through your living room.
5. 5
   Sanitizing and deodorizing. We treat the decking, joists, and any hard surfaces with an antimicrobial fog that neutralizes rodent odor compounds. If ductwork was affected, we flag it for you to have cleaned by a licensed duct company, we don’t cross trades.
6. 6
   Exclusion and restoration. We seal entry points with galvanized hardware cloth and sealant, re-insulate to the right R-value for Anaheim’s climate, and walk you through the finished attic with before-and-after photos. Every job carries the Done Right Promise: if it’s not done right, we make it right, no runaround.

What Knauf Attic Cleaning & Rodent Proofing Costs in Anaheim

Here’s what we typically see on Anaheim jobs, based on attic square footage and condition:

• Basic cleanout, small attic (under 800 sq ft), light rodent activity: $1,200 to $1,800
• Full cleanout with sanitizing and deodorizing, medium attic (800 to 1,500 sq ft): $1,800 to $2,800
• Complete cleanout, exclusion, and blown-in Knauf replacement, large or heavily contaminated attic: $2,800 to $3,800 and up

What moves the price: attic access (pull-down stairs keep it cheaper, a small hatch adds labor), how much insulation is contaminated, how many entry points need exclusion work, and whether you’re replacing with the same R-value or upgrading. We’ll also give you a free second opinion on any written estimate from another contractor, and if you’re a senior or veteran, it’s 10% off, always. Call (657) 214-8224 for an exact number, estimates are free.
