This page is for Long Beach homeowners who already have Johns Manville blown in insulation and need it topped off, removed, or replaced, plus owners deciding whether Johns Manville is the right product for their attic. We’ll cover what fails, what it costs here, and how we handle a Johns Manville job differently than the next guy.

How Johns Manville Products Fail – and How We Fix Them

Johns Manville makes solid insulation, but every product has weak points. These are the specific failures we see on Johns Manville blown in jobs across Long Beach, from Naples to Bixby Knolls.

• Climate Pro settling below its rated R-value. Climate Pro is a loose-fill fiberglass product rated to hold its loft when installed to spec. But when a previous contractor under-installed the bag count or ran the hopper too fast, the material never reaches its labeled depth. In Long Beach, where summer attics hit 140 degrees, a thin layer of Climate Pro lets heat pour through. We pull depth markers, measure in multiple bays, and top off to the bag-count spec Johns Manville publishes, not a guess.
• Attic Protector losing effectiveness after a roof leak. Attic Protector is a formaldehyde-free fiberglass blown in product that trades well for allergy-sensitive households. But fiberglass does not dry out well after a leak. It mats down, holds moisture against the drywall below, and rusts out can light boxes. We’ve pulled Attic Protector in Lakewood Village attics where a small ridge vent leak turned three feet of insulation into wet paperweight. We remove and replace, and we do it before mold becomes a bigger invoice.
• Contamination from rodents nesting in loose-fill. Rats and mice love blown in fiberglass. It’s soft, warm, and private. Once they nest, the insulation is ruined, not just “dirty.” We see this constantly in older Long Beach neighborhoods with detached garages and overgrown citrus trees. The fix is not to fluff it up. We remove the contaminated material, air seal the entry points, and blow fresh Johns Manville product back in.
• Overblown attics with blocked eave vents. You can have too much insulation. When a homeowner or a handyman keeps adding bags to fix a comfort problem without air sealing first, the loose-fill drifts into the soffit vents and shuts down attic ventilation. In Long Beach’s marine layer climate, that means condensation on the underside of the roof deck by March. We correct the depth, install baffles, and restore airflow before adding any new material.
• Old Johns Manville batts mixed with new blown in. A lot of Long Beach attics have 1970s-era Johns Manville batt insulation underneath newer blown in material. When the batts are compressed or torn, you lose the thermal break. We assess the existing layer before we ever open a bag. Sometimes the right answer is full removal. Sometimes it’s a targeted top-off. We’ll tell you which one you actually need, in writing.

Our Johns Manville Blown In Insulation Process

Every Johns Manville job in Long Beach follows the same discipline. No shortcuts, no improvising, no surprises at the invoice.

1. 1
   Call and schedule. A live person answers, 24/7. We book a two-hour window, not an all-day “we’ll be there sometime.”
2. 2
   Attic inspection and measurement. Our technician walks the attic, checks the current R-value, looks for air leaks, moisture, and pest activity. We take photos so you see what we see.
3. 3
   Written price before tools leave the truck. The number we hand you is the number you pay. It covers the material, the labor, and the cleanup. No add-backs, no “we found something else.” If we find something else during the job, we stop, show you, and price it separately before continuing.
4. 4
   The blow or the removal. For top-offs, we run Climate Pro to the density Johns Manville specifies. For removals, we vacuum out the old material and bag it out through the attic access or a window, leaving the space clean for re-insulation.
5. 5
   Verification. We re-measure depth and density in multiple points, check that eave vents are clear, and confirm the bag count. Then we show you the numbers against the product spec.
6. 6
   Written guarantee. Every job is covered by the 365-Day Done Right Promise. If the work fails within a year, we come back at no charge. That’s in writing, and it’s non-negotiable.

What Johns Manville Blown In Insulation Costs in Long Beach

Here’s the honest range for the most common Johns Manville blown in scenarios we quote in Long Beach:

• Top-off an existing attic to R-38 (Climate Pro): $1,100 to $1,800 for a typical 1,200 to 1,500 square foot attic.
• Full removal and replacement (Attic Protector): $2,200 to $3,800 when the existing insulation is contaminated, wet, or compressed past saving.
• Air sealing plus blown in top-off: Add $700 to $1,200 to the top-off range, depending on attic complexity and the number of penetrations.

What moves the price: square footage, current R-value, whether the old material needs removal, and how accessible your attic access is. A third-floor attic with a scuttle in a closet costs more to service than a walk-up. Call (562) 317-6204 for a written quote. Estimates are free, and the number we quote is the number on the invoice.
