Knauf Blown-In Insulation in Los Angeles: What to Know First
We install, top up, and replace Knauf blown-in insulation in Los Angeles homes and businesses, and we do it the way the product was designed to be done: dense enough to work, verified with thermal imaging, and guaranteed.

How Knauf Products Fail - and How We Fix Them
Knauf makes solid insulation, but no blown-in product is set-and-forget in Los Angeles. Here’s what we see in the field, and what we actually do about it.
- Knauf Jet Stream Ultra settling in attics. This fiberglass blown-in line is common in L.A. attics, and after five to ten years we routinely measure 15-20% settling, especially where original installers blew it too light. The result is a thermal gap at the top of the assembly. We top up with Knauf Jet Stream Ultra to the correct depth and verify coverage with a thermal camera, not a guess.
- Knauf EcoFill WX dense-pack voids in older walls. Dense-packing older Los Angeles walls through small drill holes is precise work. If the installer didn’t hit the right density of 3.5 pounds per cubic foot, you get voids behind the drywall that show up as cold bands on a winter morning. We re-dense-pack to Knauf’s specified density and check every cavity with an infrared scan.
- Cellulose or fiberglass contamination after roof leaks. Knauf’s blown-in products lose R-value once they get wet. In neighborhoods like Silver Lake and Echo Park with older roof flashing, a small leak can saturate attic insulation for months before the ceiling stain shows. We remove the compromised material, air-seal the source, and re-blow with fresh Knauf product.
- Pest intrusion through unsealed penetrations. Rats and squirrels in Los Angeles attics don’t care what brand your insulation is. They tunnel through Knauf blown-in fiberglass, compress it, and replace the air pockets with nesting material. We remove the damaged insulation, rodent-proof the entry points, and re-install clean Knauf fill.
- Inadequate depth from cut-rate original installs. We measure attics in places like West Adams and Reseda that meet code for a 1990s install but fall far short of today’s R-38 recommendation for Los Angeles County. A top-up with Knauf blown-in fiberglass is a half-day job that returns measurable savings in the first year.

The install. Our background-checked, uniformed technicians run the Knauf blowing machine, hit the correct coverage and density, and keep the work area clean. Most jobs finish in one visit.
- 5
Verification and cleanup. We re-scan with the thermal camera to prove coverage, remove all equipment, and walk you through what was done.

FAQs
No, adding blown-in insulation over existing Knauf material does not void the manufacturer’s warranty, provided the existing material is dry and in good condition and the new material is installed to Knauf’s specified depth and density. We document every job with photos and thermal scans so you have a record if a warranty claim ever comes up.
Most Knauf blown-in jobs are completed in a single visit, and we can often schedule within a few days of your call. Attic top-ups are usually a half-day job; removal and re-installation can take a full day depending on attic size and access.
If the existing Knauf insulation is dry, free of pest damage, and not heavily settled, topping up is significantly cheaper than full replacement. In Los Angeles, a top-up costs roughly half to one-third of a full removal and re-blow. We only recommend replacement when moisture, rodents, or severe contamination make it necessary. Call (213) 782-8141 and we’ll tell you honestly which one your home needs.
