How Johns Manville Products Fail - and How We Fix Them

Johns Manville makes decent insulation, but every product has weak points. Here’s what we actually see in West Hollywood attics, and what we do about it.

• JM ComfortTherm batts losing their vapor barrier. The kraft paper facing on these batts was never designed to handle the humidity swings we get between the coast and the hills. Once that facing peels away or tears, the batt loses its air-sealing function and starts collecting condensation. We remove the compromised batts, assess the framing underneath, and replace with material matched to the specific attic conditions, not just whatever is on the truck.
• JM Spider blown-in fiberglass settling to half its original depth. This is the one we see most often in older West Hollywood condo buildings. Spider was never a dense-pack product, and after 15 to 20 years it can compress enough to drop below R-30 effectiveness in spots. The fix isn’t topping it off; the old material has to come out so we can verify the attic floor and any ductwork before reinstalling.
• Moisture-wicked JM fiberglass from roof leaks or bathroom vent problems. Fiberglass doesn’t rot, but it does hold water against framing and drywall. Once it’s wet, the R-value drops close to zero and it stays that way. We remove the wet material, find the actual source of the moisture, and only then put in new insulation. Skipping step two just means pulling it out again next spring.
• Rodent-damaged and contaminated JM batts. Rats and mice in West Hollywood attics don’t discriminate by brand. If they’ve been living in your Johns Manville insulation, it’s gone: urine-soaked fiberglass isn’t something to clean, it’s something to remove. We handle the removal, sanitize the attic deck, and can do rodent proofing in the same visit if needed.
• Vermiculite and old loose-fill that homeowners assume is Johns Manville. Sometimes what’s up there isn’t what the sticker says. If we find vermiculite or an unidentifiable loose-fill, we stop and test before touching it. This is a safety call, not an upsell. You can’t tell what’s in old insulation by looking at it.

Our Johns Manville Insulation Removal & Replacement Process

Here’s what actually happens when you call us for a Johns Manville insulation job in West Hollywood:

1. 1
   You call, and a person answers. Walt Brenner or one of our crew members picks up, day or night. If it’s urgent, we’ll tell you honestly whether it is.
2. 2
   We inspect what’s up there. We look at the type of Johns Manville product, its age, moisture levels, signs of pests, and how much material we’re dealing with. We’ll show you photos of what we find.
3. 3
   We give you a written estimate. No vague numbers, no “we’ll see how it goes.” The price we quote is the price you pay, and seniors and veterans get 10% off, permanently.
4. 4
   We remove the old material. Commercial HEPA-filtered vacuums for loose-fill or contaminated insulation, hand removal for batts. We seal off the work area and protect your home from dust.
5. 5
   We prep the attic and install the replacement. That means air sealing, checking ventilation, and then installing new insulation, whether it’s fresh Johns Manville, Owens Corning, Rockwool, Knauf, or another brand that fits the job better.
6. 6
   We walk you through the work and leave it clean. You’ll see before-and-after photos. The Done Right Promise covers the workmanship for life. If it’s not done right, we make it right.

Why West Hollywood Homeowners Call Walt’s Insulation for Johns Manville Work

We’ve been doing this since 2000, and we’re not a franchise or a call center. Walt’s Insulation is the one down the road: locally owned, owner-operated, with a published address and a license number you can verify. That matters when someone’s going to be in your attic for two days. Every technician who shows up is background-checked and in uniform, so you know exactly who’s walking through your door.

We work across all the major insulation brands, including Owens Corning, Rockwool, CertainTeed, Knauf, Icynene, and GreenFiber, plus Reflectix for radiant barrier applications. That means when we tell you a replacement material is the right one for your West Hollywood home, it’s because it is, not because it’s our only option. And if anything isn’t right, the Done Right Promise means we come back and fix it. That’s not a warranty card in a drawer; it’s how we’ve stayed in business for over 25 years.

We do the job right the first time, because coming back to fix it isn’t good for either of us.
