GreenFiber Attic Cleaning & Rodent Proofing Nationwide

GreenFiber Attic Cleaning & Rodent Proofing in Long Beach: What to Know First

We provide independent GreenFiber attic cleaning and rodent proofing in Long Beach, typically completing most jobs in one to two days with a written price before any work starts. Most GreenFiber attic cleanouts and rodent exclusions in Long Beach run between $1,800 and $4,200 depending on contamination level, accessibility, and whether the cellulose can be salvaged or must be fully removed. This page is for homeowners who found rodent droppings, nesting material, or compressed GreenFiber insulation in their attic and need a crew that understands how cellulose behaves differently from fiberglass when it’s been compromised.

How GreenFiber Products Fail - and How We Fix Them

• Low Dust cellulose settling in vaulted ceilings. GreenFiber’s Low Dust line, common in 2018-2022 Long Beach installs, settles 15-20% in the first three years when blown at manufacturer-specified density in cathedral ceilings with inadequate vent baffles. The settled material creates a thermal bridge at the ridge and leaves exposed drywall where rodents travel. We remove the settled pack, install proper vent chutes, and re-blow at stabilized density with air sealing completed first.
• Sanctuary product absorbing urine and holding odor. GreenFiber Sanctuary, the treated cellulose marketed for pest resistance, still absorbs rodent urine because the borate treatment deters insects, not mammals. In Long Beach’s marine climate, that urine load reactivates with humidity spikes, particularly in Belmont Shore homes without adequate vapor diffusion. We extract contaminated Sanctuary, apply enzymatic decontamination to the substrate, and reinstall only after moisture readings stabilize below 15%.
• INS515LD all-borate settling against top plates. The INS515LD loose-fill product, frequently found in Bixby Knolls bungalows with 2×4 ceiling joists, settles away from top plates during seasonal humidity cycling, creating a gap that rodents exploit as a highway. We find this gap with a thermal camera, seal the top plate with acoustical sealant and rigid blocking, then re-establish continuous insulation coverage.
• Fireblock product bridging over recessed cans. GreenFiber Fireblock, required by California Title 24 in certain assemblies, is often blown over unsealed IC-rated can lights by installers who skipped the air-sealing step. The cellulose bridges across the hot fixture, creating a scorch pattern and a void where rodents nest. We pull back the compromised Fireblock, seal each can with a pre-formed cover and fire-rated caulk, then reinstall the material to proper depth.
• Subfloor product compression from foot traffic during duct work. GreenFiber Subfloor, installed in Long Beach crawl spaces and some low-slope attics, compresses to half its labeled R-value when HVAC techs walk on it repeatedly. The compressed mat holds moisture and rodent trails. We gauge actual depth with a probe, remove only the compressed sections, and reinstall at 1.5 pounds per cubic foot minimum density with walk boards for future access.

Our GreenFiber Attic Cleaning & Rodent Proofing Process

1. 1
   Inspection and documentation. We photograph existing GreenFiber depth, contamination pattern, and rodent entry points. We measure actual R-value with a calibrated probe, not the labeled bag number.
2. 2
   Written scope and price. You receive a one-page report listing pre-install depth readings, contamination severity, air-sealing locations needed, and a flat price. No work starts without your written approval.
3. 3
   Air sealing before any material touches the attic. Top plates, wire penetrations, can lights, and chimney chases are sealed with appropriate materials. We run a blower-door test before and after this step when the home’s envelope allows it.
4. 4
   GreenFiber-specific removal or salvage. We use a high-volume extraction unit with HEPA filtration designed for cellulose, not fiberglass vacuums retrofitted. Salvageable GreenFiber is bagged and stored; contaminated material is disposed of per California waste codes.
5. 5
   Decontamination and rodent exclusion. Enzymatic treatment of substrates, then mechanical exclusion with galvanized steel mesh at entry points 1/4 inch or larger. We do not use spray foam as exclusion material; rodents chew through it in six months in our experience.
6. 6
   Reinstall, verify, and document. New or salvaged GreenFiber is blown to specified depth. Post-install depth readings, photos, and a written record of air-sealing locations and exclusion work are delivered before we leave.
