How Johns Manville Products Fail - and How We Fix Them
Johns Manville makes solid insulation, but nothing lasts forever, especially in Torrance’s marine layer humidity and summer heat. Here’s what we actually find when we open up attics in this city:
- JM ComfortTherm batts with moisture-wicking facing: ComfortTherm’s kraft facing is designed to manage moisture, but in Torrance’s damp coastal air, that facing can trap condensation against the drywall below if the attic ventilation is weak. We see this a lot in homes near the Del Amo corridor. The fix is full removal, a ventilation check, and a reinstall with the right vapor barrier strategy for your specific attic.
- Climate Pro blown-in fiberglass settling: Climate Pro is a good product, but after 10 to 15 years in a Torrance attic, we routinely find it has settled to half its original R-value, especially in homes where people stored boxes on top of it. Removal is straightforward: we vacuum it out, air seal the penetrations, and blow in fresh material at the correct depth for your R-value target.
- Attic Protector formaldehyde-free batts with rodent damage: Rats and mice love tearing JM batts into nesting material, and Torrance’s mature landscaping gives them plenty of cover. Once rodents get in, the insulation gets shredded, packed down, and soaked with urine. We remove it under containment, sanitize the attic, and rodent-proof before new insulation goes in.
- Vermiculite from pre-1990 homes: If your older Torrance home has vermiculite insulation, it may contain asbestos. We don’t disturb it without testing first. If it tests positive or you want it gone regardless, we handle removal following California safety protocols, and we’ll work with a certified asbestos abatement partner when required.
- JM kraft-faced batts installed upside down: It’s depressingly common. The facing goes toward the living space, and when a previous installer flipped it or skipped it entirely, the insulation underperforms and can trap moisture where you don’t want it. We fix it by removing the old work and reinstalling correctly, with the facing placement right for Torrance’s climate zone.
Our Johns Manville Insulation Removal & Replacement Process
Here’s what a typical Johns Manville removal and replacement job looks like with us, start to finish:
- 1
We show up when we say we will. Background-checked, uniformed techs arrive in a marked truck. You know who’s walking into your house.
- 2
We inspect and test. We check what type of JM product is installed, measure current R-value, look for moisture, rodent activity, and air leaks. If vermiculite is present, we stop and test before anything moves.
- 3
We quote upfront. You get a written price before work starts. No surprise line items. We’ll tell you if the old insulation can come out in one day or if it’s a two-day job.
- 4
We remove under containment. HEPA-filtered vacuums for blown-in material, bagging for batts. We keep dust out of your living space and we don’t track insulation through your house.
- 5
We prep the attic right. Air sealing, ventilation check, rodent proofing if needed. Putting new insulation over the same problems is throwing money away, and we won’t do that to you.
- 6
We install fresh insulation and clean up. New Johns Manville material, or another brand if it’s a better fit for your attic (we also install Reflectix radiant barrier and other brands). Then we leave the space cleaner than we found it, and the whole job is covered by the Done Right Promise for life.

Why Torrance Homeowners Call Walt’s Insulation for Johns Manville Work
Walt Brenner started this company in 2000, and he’s been the one down the road for Torrance homeowners ever since. His crew has worked attics all over the South Bay, including tight retrofit jobs near the Del Amo Fashion Center corridor where headroom is scarce and summers are brutal. A shop instructor at San Antonio College once told Walt that insulation is “the most thankless job that matters most,” and he’s never forgotten it. Good insulation doesn’t announce itself, you just stop noticing the problem.
When you call us for Johns Manville removal and replacement, a live person answers. Not a voicemail, not an answering service, not a call center in another state. You talk to someone who works here, who lives near here, and who can answer questions about JM Climate Pro settling rates or ComfortTherm facing placement without putting you on hold to go Google it. If we recommend removal, we’ll tell you why. If we think your existing insulation just needs an air sealing fix, we’ll tell you that too. Our work is backed by the Done Right Promise: if it’s not done right, we make it right. For life. Seniors and veterans always get 10% off. Always.
Frequently Asked Questions
Johns Manville’s product warranty covers defects in the material itself, not removal or labor, and most warranties are voided by contamination, moisture exposure, or improper installation. As an independent Johns Manville service provider, we don’t process warranty claims for the manufacturer, but we can help you document what we find so you can pursue a claim if one exists. For our part, every removal and replacement job is covered by the Done Right Promise for life.
Most Torrance attics with blown-in material take one full day for removal and one day for new insulation installation. Contaminated jobs with sanitizing and rodent proofing can run two to three days. We’ll give you a timeline with your written estimate, and we’ll stick to it. Call (424) 955-2557 for a schedule check, we answer live 24/7.
Yes, and we’ll usually recommend going higher. Older Torrance homes often have R-19 or R-30 in the attic, and California’s current building code wants R-38 or better. We’ll match what’s there if that’s what you want, but we’ll show you the payback math on upgrading while the attic is already open. The marginal cost of going from R-30 to R-38 is small compared to the energy savings over the next decade.
You don’t always have to. If the old Johns Manville insulation is dry, uncontaminated, and just settled, we can sometimes top it off. But if there’s rodent activity, moisture damage, or mold, adding new insulation buries the problem and makes it worse. We’ll tell you straight which situation you have, and we won’t sell you removal you don’t need. That’s not how Walt’s operates.
Yes. We install Owens Corning, Rockwool, CertainTeed, Knauf, GreenFiber, and others, plus Reflectix radiant barrier. If another brand is a better fit for your Torrance attic, we’ll tell you and explain why. Our job is to fix your house, not to push one manufacturer’s product.
