This page is for homeowners who already have Knauf insulation in their West Hollywood walls, or who are considering it for a remodel or addition. If you’re dealing with cold rooms, noise bleeding through shared walls, or drafts that showed up after a previous insulation job, you’re in the right place. We’re Walt’s Insulation, and we’ve been working on West Hollywood homes since 2000.

How Knauf Products Fail - and How We Fix Them

• Knauf EcoBatt settling in older West Hollywood stud bays. EcoBatt fiberglass is a solid product, but in homes built before California’s Title 24 energy code got serious, stud bays are often irregular or underfilled. We regularly find EcoBatt that’s slumped six to eight inches below the top plate, leaving a thermal gap right where heat escapes. We pull the old batts, air-seal the cavity, and refill to full depth. It’s not the product’s fault. It’s an installation problem, and it’s fixable.
• Knauf Jet Stream blown-in wall cavities with voids behind electrical boxes. Jet Stream works well in open bays, but in West Hollywood’s older apartment conversions and duplexes, we find voids behind outlets and switch boxes where the original installer never got good coverage. Those voids act like open windows. We use a borescope to verify fill density, then top off those cavities with injection foam through the existing access points.
• Knauf R-15 or R-13 kraft-faced batts installed backward in framed exterior walls. The kraft facing always goes toward the conditioned side, but we see it flipped in West Hollywood homes more often than anywhere else we work. Facing against the exterior sheathing traps moisture inside the wall cavity, which eventually leads to mold, musty smells, and degraded insulation performance. The fix is straightforward: we remove, check the sheathing for damage, and reinstall correctly.
• Knauf Insulation Board (KIB) on interior party walls with air gaps at joints. In condos and townhomes near Santa Monica Boulevard, sound transmission through shared walls is a constant complaint. Knauf’s rigid boards do a decent job, but if the joints aren’t staggered and sealed, sound finds the gaps. We take the wall down to the studs when needed, seal every seam with acoustic caulk, and stagger the board joints so there’s no continuous path for noise.
• Knauf insulation compressed around plumbing and electrical runs in exterior walls. Compression kills R-value. When insulation gets jammed behind pipes or wiring, it loses a third or more of its rated performance in that area. In West Hollywood, where many homes share walls and chase lines run through exterior cavities, this is a common headache. We notch and split the insulation to fit around penetrations instead of crushing it, then seal around the penetrations to stop air movement.

Our Knauf Wall Insulation Process

Here’s how a typical Knauf wall insulation job goes from start to finish at Walt’s Insulation:

1. 1
   Call and talk to a real person. You call (213) 527-4062. Walt or one of our techs answers. We ask about your house, your symptoms, and what you’ve already tried. No call center. No script.
2. 2
   On-site inspection with a thermal camera. We come out to your West Hollywood home and walk the walls with a thermal imaging camera and a borescope. We’re looking for voids, settling, moisture, and any air sealing gaps. We check inside outlets, behind baseboards, and in the attic above the wall top plates.
3. 3
   Straightforward quote with no surprises. We write up what we found, what we recommend, and what it’ll cost. You get a line-item quote, not a hand-wave estimate. We don’t bundle things you don’t need, and if you already have a written estimate from someone else, bring it in. We’ll give you a free second opinion, no charge.
4. 4
   The work, done right. We remove compromised Knauf insulation where necessary, air-seal the cavities, and install new Knauf products or a compatible option that fits your wall assembly. We use OEM Knauf materials where the job calls for them, and quality aftermarket options only where they genuinely match or exceed the spec. We never downgrade materials to pad a margin.
5. 5
   We verify before we leave. After installation, we re-scan the walls with the thermal camera to confirm full coverage. You see the before and after with your own eyes. Then we clean up. Our techs are background-checked and uniformed, and they don’t leave debris in your yard or dust in your hallway.
6. 6
   The Done Right Promise kicks in. Every Knauf wall insulation job we do is backed by our lifetime workmanship guarantee. If it’s not done right, we make it right. No runaround, no fine print. That’s the whole point of the promise, and it’s been that way since 2000.

What Knauf Wall Insulation Costs in West Hollywood

Here’s the honest math on Knauf wall insulation in West Hollywood, based on what we’ve quoted and installed over the years:

Typical Knauf Wall Insulation Pricing

• Drill-and-fill injection foam into existing exterior walls: $3.00 to $4.20 per square foot of wall area. A standard 1,500 square foot West Hollywood home with 900 square feet of exterior wall usually lands between $2,700 and $3,800.
• Knauf EcoBatt or R-15/R-13 batts for new construction or gut-remodel walls: $1.80 to $2.60 per square foot installed, depending on stud spacing and wall height.
• Interior party wall soundproofing with Knauf insulation board or mineral wool: $2.20 to $3.40 per square foot, including acoustic caulking and joint sealing.
• Removing and replacing failed Knauf insulation in existing walls: Add $0.60 to $1.00 per square foot for removal, disposal, and cavity prep before new insulation goes in.

What moves the price: wall accessibility (are we working from inside or outside?), plaster versus drywall, how many plumbing and electrical penetrations we have to work around, and whether you need air sealing in the same pass. In older West Hollywood buildings near the Sunset Strip and the flats, plaster walls add labor because we’re often patching lathe and matching texture. We give you a firm price before we start. No trip charge anywhere in Los Angeles County. Call (213) 527-4062 for an exact quote on your walls, and remember, seniors and veterans always get 10% off. That’s permanent.

Why West Hollywood Homeowners Call Walt’s Insulation for Knauf Work

We’re the one down the road. Walt’s Insulation has been a local West Hollywood presence since 2000, and Walt Brenner himself is still the guy who answers the phone most days. You’re not calling an 800 number that rings in another state. You’re calling a business with a published address, a real license number, and a last name attached to it. When we say the Done Right Promise backs your Knauf wall insulation, that’s Walt’s name on it, not a corporate legal team’s.

Our techs know Knauf products, but they also know Owens Corning, Rockwool, Johns Manville, CertainTeed, Icynene, Demilec, GreenFiber, and when a specialty product like Reflectix is the right call for a radiant barrier. That matters because sometimes the right fix for a Knauf wall problem isn’t Knauf. Sometimes it’s a hybrid approach that combines what’s already in your walls with a product that solves a specific issue. We’d rather tell you the truth and do the job correctly than sell you a brand name. We do the job right the first time, because coming back to fix it isn’t good for either of us.
