How Johns Manville Products Fail – and How We Fix Them

Johns Manville makes decent insulation, but Los Angeles attics punish it in ways the manufacturer’s warranty sheet doesn’t prepare you for. Here’s what we actually see when we open up attics around LA:

• Formaldehyde-bonded fiberglass (pre-2002 ComfortTherm and older JM batts). These break down in high attic heat, and that’s the smell people assume is “just an old house.” In a Los Angeles summer, an attic hits 140 degrees routinely, and old JM batts release more of that chemical odor as they degrade. Full removal plus air sealing is the only real fix. We bag it in sealed contractor bags on-site, never loose through the house.
• JM Attic Protector blown-in fiberglass settling below R-value. Blown-in fiberglass settles over time, and in LA’s dry climate it also gets brittle. We regularly pull out Attic Protector that’s measured 8 inches deep when the bag said it should be 14 for R-38. Once it’s compressed and dusty, no amount of fluffing brings it back. Removal and a clean start with new blown-in material makes more sense than layering on top.
• JM EasyFit batts with rodent damage. Rats and mice in Los Angeles attics love fiberglass for nesting. They shred EasyFit batts into confetti, and that torn material mixed with droppings means removal isn’t optional, it’s a health call. We do full contamination removal with HEPA filtration and sanitize the deck before anything new goes in.
• Moisture-saturated batts from roof leaks or condensation. A JM batt that’s been wet loses its loft permanently. In older Los Angeles homes with no ridge vent or inadequate soffit vents, condensation builds at the roof deck and soaks the top layer of insulation. Wet fiberglass holds no R-value, supports mold growth, and compresses under its own weight. We pull it, assess the ventilation, and recommend the fix before reinsulating.
• DIY layering mistakes on top of existing JM product. We see a lot of attics where someone added unfaced batts over old JM faced batts, which traps moisture between layers. Or they blew cellulose over original 1970s JM fiberglass without air sealing first. These layered installs don’t perform and often hide problems underneath. Removing everything down to the drywall gives us a clean deck for the right air sealing and new insulation, and it’s the only way to actually fix what’s happening below.

Our Johns Manville Insulation Removal Process

Here’s what a Johns Manville removal job looks like when we do it in a Los Angeles home:

1. 1
   We inspect and give you a written price. A technician measures square footage, checks access (scuttle hole, pull-down ladder, or quarter-turn stair), notes the material type, and confirms whether there’s contamination. You get the dollar amount in writing before we touch anything.
2. 2
   We set up containment. Plastic sheeting protects the access point and the path from attic to door. Our HEPA vacuum runs during the whole removal to keep airborne fiberglass dust from moving through your house.
3. 3
   We remove the Johns Manville material. Batts get bagged by hand in sealed contractor bags. Blown-in fiberglass gets vacuumed out with a commercial insulation removal vacuum that pulls material directly into collection bags outside. Nothing loose gets carried through your living space.
4. 4
   We inspect the substrate. Once the old material is out, we check the ceiling drywall, look for rodent entry points, inspect wiring, and assess ventilation. This is the step that tells us what caused the original problem so it doesn’t just repeat.
5. 5
   We clean and prep. The attic deck gets vacuumed clean. If you’re proceeding with new insulation, we air seal gaps and penetrations now, before any new material goes in.
6. 6
   You get photo proof. Before and after photos are delivered to your phone, and your guarantee is in writing on the digital invoice. If anything’s not right within 365 days, we come back and make it right.

What Johns Manville Insulation Removal Costs in Los Angeles

Most Johns Manville removal jobs in Los Angeles run between $1.75 and $3.25 per square foot. A typical 1,200-square-foot attic with blown-in fiberglass lands around $2,100 to $3,900. Here’s what moves the price:

• Material type: blown-in fiberglass vacuums fast; dense-packed batts pulled by hand take more labor.
• Access: a full staircase is faster than a 22-inch scuttle hole, and LA homes built before 1950 tend to have the tight access points.
• Contamination: rodent droppings, water damage, or mold add containment time and disposal fees.
• Disposal volume: heavier material means more trips to the landfill, and Los Angeles County transfer stations charge by the ton.

We quote a fixed price before work starts, so the number we give you is the number you pay. Call (361) 315-4177 and we’ll measure it, look at the attic, and put the price in writing.
