Johns Manville Attic Cleaning & Rodent Proofing in Inglewood: What to Know First
Johns Manville attic cleaning and rodent proofing in Inglewood typically runs between $900 and $2,800 depending on attic size, infestation severity, and how much contaminated insulation needs removal. We complete most Johns Manville attic restoration jobs in a single visit, and we’re an independent Johns Manville service provider, not a manufacturer-authorized contractor. That independence matters: it means we recommend what’s actually right for your attic, not what a corporate warranty program dictates.

How Johns Manville Products Fail - and How We Fix Them
Johns Manville fiberglass batts and blown-in insulation are solid products. But in Inglewood’s coastal climate, with our warm days, cool nights, and determined rodent population, they fail in predictable ways. Here’s what we actually see up there:
- Johns Manville ComfortTherm batts with kraft facing get shredded into nesting material. Rodents strip the paper vapor barrier off the batts and carry it into wall cavities and soffits to build nests. The exposed fiberglass then loses its R-value fast. We remove the destroyed batts, seal entry points, and re-insulate with fresh material paired to your attic’s existing Johns Manville product.
- Blown-in Johns Manville Climate Pro fiberglass settles after rodent traffic. Rats and mice burrow through the loose fill, creating tunnels and compressed pockets where insulation drops to a fraction of its rated depth. Your attic may have looked like R-38 when it was installed. After a season of rodent activity, some sections test closer to R-11. We map the attic, remove the contaminated fill, and blow in new material at full depth.
- Urine saturation in Johns Manville fiberglass can’t be cleaned off. Once rodent urine soaks into blown-in fiberglass or batt facing, the odor is permanent. Sanitizing sprays only mask it. The fix is full removal of the affected section, attic decontamination with an enzyme-based treatment, and fresh insulation. We see this constantly in the neighborhoods around Morningside Park and up toward Century Boulevard.
- Johns Manville Attic Protector radiant barrier gets chewed through at the soffit line. Reflective foil materials attract rodent attention where they meet roof decking. Once punctured, moisture gets behind the barrier and the reflective performance drops. We repair or replace the damaged run, then install exclusion mesh at every soffit and roof junction to keep animals out permanently.
- Compressed fiberglass around attic penetrations hides the real entry points. Plumbing vents, recessed light housings, and HVAC chases are where rodents push through Johns Manville insulation and into your living space. The insulation damage is a symptom. We find the gap, seal it with professional-grade exclusion materials, and only then replace the insulation. Sealing without replacing means odors and soaked material stay. Replacing without sealing means you’ll see the problem again in six months.
Our Johns Manville Attic Cleaning & Rodent Proofing Process
Every Johns Manville attic job in Inglewood follows the same sequence. No shortcuts, no mystery.
- 1
Attic inspection and diagnosis. We map your entire attic, identify every entry point, test insulation depth, and photo-document everything. You get to see what we see, before any work begins.
- 2
Rodent exclusion planning. We locate how animals are getting in, often through gaps hidden behind Johns Manville insulation at the roofline. We identify every opening down to the quarter-inch, the size a juvenile mouse needs.
- 3
Insulation and debris removal. Contaminated Johns Manville material comes out first. Full vacuum removal, bagged and removed from your property, not left in your driveway.
- 4
Attic sanitizing and decontamination. We treat all affected surfaces with a commercial-grade enzyme decontaminant that neutralizes rodent waste and odor at the source. Not a fragrance spray. A decontaminant.
- 5
Air sealing and exclusion installation. Every gap, crack, and penetration gets sealed. Then we install professional exclusion barriers at all entry zones, including soffit vents, roof junctions, and pipe penetrations.
- 6
Fresh Johns Manville-compatible insulation install. We re-insulate to appropriate R-value for your home and verify the finished depth. You get a clean, sanitary attic that stays that way, backed by our 90-Day Done Right Promise.
