How Johns Manville Products Fail - and How We Fix Them

Johns Manville makes solid insulation. But Burbank’s specific climate and housing stock create failure patterns we see on a weekly basis. Here’s what actually goes wrong:

• Fiberglass batt compression in 1950s-1970s Burbank attics. Older homes near Magnolia Park and the Verdugo foothills often got R-19 batts packed into shallow 2×6 ceiling joists, which compresses the fibers and guts the R-value. We routinely pull compressed Johns Manville ComfortTherm batts and replace them with blown-in fiberglass at the correct depth for a true R-38.
• Blown-in fiberglass settling below code. Attic Protector loose-fill is designed to resist settling, but Burbank’s summer heat cycling combined with decades of foot traffic from cable installers and AC techs can compress it by 30% or more. We measure the actual depth and top up to current Title 24 standards, not just whatever looked fine in 1998.
• Kraft-faced batts installed upside down in DIY jobs. We see this constantly in Burbank homes that were “insulated” by a previous owner or a handyman. The vapor retarder ends up facing the attic, trapping moisture against the drywall and breeding mold. The fix is removing and reinstalling, or switching to unfaced blown-in coverage.
• Missing baffles causing ice-dam-style moisture issues. Johns Manville insulation against the roof deck without proper baffles blocks soffit ventilation. In Burbank’s winter rains, warm attic air condenses against the fiberglass, soaking it and cutting its effectiveness. We install baffles and verify airflow before adding any material.
• Pest contamination in existing fiberglass. Rats and mice in Burbank attics tunnel through Johns Manville batts, shred the facing, and leave behind waste that ruins the product’s integrity and your air quality. We include removal, sanitization, and rodent proofing with Johns Manville replacement jobs where the damage warrants it.

Our Johns Manville Attic Insulation Process

Every Johns Manville job we run in Burbank follows the same sequence, whether it’s a top-up or a full removal and replacement:

1. 1
   We inspect the entire attic. Neil Ashford or one of our senior techs documents current R-value, checks for air leaks around can lights, plumbing penetrations, and the attic hatch, and looks for moisture or pest signs. You get photos and straight answers.
2. 2
   We air seal first. Insulation without air sealing just traps warm air in your attic. We seal the bypasses that matter, then layer insulation over a clean, sealed ceiling plane.
3. 3
   We choose the right Johns Manville product for your home. For most Burbank attics, that’s loose-fill blown-in fiberglass at the correct depth. If you have specific needs, like a storage deck, we’ll spec the right batt product instead.
4. 4
   We remove or top up as needed. Contaminated or compressed material comes out. Underperforming but sound material gets topped to code. You’ll know which applies before we start.
5. 5
   We verify depth and coverage. We use depth markers in every bay so you can see exactly what you’re getting, no guesswork.
6. 6
   We clean up and walk you through it. The job site gets vacuumed, and we show you the finished attic before we leave. Every Johns Manville job carries our 90-Day Done Right Promise: if it’s not done right, we make it right.

What Johns Manville Attic Insulation Costs in Burbank

Here’s what you can expect to pay in Burbank for common Johns Manville scenarios:

• Attic top-up (existing insulation under R-30): $900 to $1,900 for a typical 1,200-1,500 sq. ft. attic.
• Full attic insulation replacement (removal + new blown-in): $2,200 to $4,200 depending on attic size, access, and contamination.
• Batt installation for storage areas or vaulted ceilings: $1,400 to $2,800 for Johns Manville ComfortTherm or TempControl batts.
• Air sealing + insulation bundle: $2,500 to $4,800 for the full treatment, which is where the actual energy savings come from.

Price moves on attic square footage, how much old material needs to come out, and whether we’re fixing ventilation issues at the same time. You’ll get an upfront price before any work begins, no surprises. Mention the 5% Senior & Veteran discount when you call, and ask about the $50 Off Any Repair Over $250 and the $89 Seasonal Tune-Up.
