This page is for West Hollywood homeowners who’ve discovered rodent activity, nesting, or soiling in a Rockwool-insulated attic and need someone who understands how stone wool behaves differently than fiberglass or cellulose when contaminated.

How Rockwool Products Fail - and How We Fix Them

• Rockwool Comfortbatt R-30 compresses unevenly under rodent trails, creating thermal bypasses. The dense, rigid batts hold their shape better than fiberglass, but repeated rodent traffic grinds the fibers into packed channels that no longer insulate. We remove the contaminated sections, air-seal the subfloor penetrations the rodents used as highways, and reinstall only if the compression is less than 15 percent. Otherwise, we replace with fresh batts and document the depth with photos.
• Rockwool Safe’n’Sound in partition walls above living spaces wicks urine deep into the fiber matrix. Stone wool is hydrophobic at the surface but capillary action still draws liquid through the interstitial spaces over months. The odor doesn’t surface until humidity spikes - common in West Hollywood’s Santa Ana wind events when attic temps hit 140°F. We HEPA-vacuum the top layer, apply enzyme treatment to the full depth, and run a moisture meter before declaring it clean. Surface-only treatment fails; we’ve seen it.
• Rockwool Comfortboard 80 used as attic floor insulation sheds rigid fragments when gnawed by roof rats. The compressed board format doesn’t tear like batt - it splinters into sharp-edged pieces that scatter through joist bays and into soffits. We collect these mechanically rather than blowing them around with a standard insulation vacuum, which would drive fragments into every corner. Our crew uses sealed HEPA recovery systems designed for dense mineral wool debris.
• Rockwool AFB (Acoustical Fire Batt) in multifamily common walls loses its fire rating when soiled. Rodent grease and organic loading compromise the intumescent performance; the batt won’t expand as designed in a fire event. We mark these locations on your photo record, note the code violation for your reference, and replace with fresh AFB where required. In West Hollywood’s older courtyard apartments near Melrose, this comes up more often than owners expect.
• Rockwool granulated blown-in (formerly Rockwool Premium Plus) settles around rodent burrow systems, leaving voids at the eaves. The loose-fill material bridges over tunnels rather than collapsing into them, so the voids are invisible from the attic hatch. We probe with rigid rods to map the hollows, remove the bridged material, and re-blow only after sealing every entry point with galvanized mesh and foam. Skipping the probe step means the next rat colony moves into the same highway.

Our Rockwool Attic Cleaning & Rodent Proofing Process

1. 1
   Assessment and written scope. We inspect the attic, identify the Rockwool product line and condition, map rodent entry points, and deliver a written price before any work starts. Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool.
2. 2
   Air sealing before disturbance. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order. We seal top plates, can lights, and plumbing penetrations with fire-rated foam and galvanized mesh so removal doesn’t drive contaminants into the living space.
3. 3
   Contaminated material removal. Dense Rockwool products require specialized HEPA recovery equipment, not standard insulation vacuums. We bag on-site, label for proper disposal, and photo-document every bay before and after.
4. 4
   Sanitizing and enzyme treatment. We apply commercial-grade decontaminant specific to organic loading in stone wool matrices, with dwell time appropriate to the contamination depth. Surface spray isn’t enough; we calculate volume, not area.
5. 5
   Rodent proofing and exclusion. Entry points get 1/4-inch galvanized hardware cloth, concrete patching where needed, and gap foam rated for the application. We also inspect for Reflectix or other radiant barriers that rats may have nested behind.
6. 6
   Replacement, verification, and documentation. Fresh Rockwool or alternative installed to spec, moisture and odor verified, and your Documented Photo Record delivered with before-and-after images. On jobs with envelope work, we provide blower-door numbers showing the air-sealing result.

What Rockwool Attic Cleaning & Rodent Proofing Costs in West Hollywood

Most Rockwool attic cleanouts in West Hollywood run between $2,800 and $5,400. Here’s what moves that number:

Factors that push higher: multiple rodent generations (deeper contamination), Comfortboard 80 requiring mechanical recovery, or access limitations in West Hollywood’s hillside homes with small hatches. Factors that keep it lower: early detection, intact vapor barrier below, and straightforward rectangular attics.

Why West Hollywood Homeowners Call Topside Attic Insulation West Hollywood for Rockwool Work

We’ve been inside enough bungalows off Santa Monica Boulevard to know that West Hollywood’s 1920s to 1950s housing stock has quirks: shallow roof pitches, original plaster-and-lath ceilings that crack if you look at them wrong, and attics that someone stuffed with whatever insulation was cheap in 1987. Wes Okafor learned the building sciences side of this trade at Olive-Harvey College in Chicago, then spent the better part of two decades doing attic work across the LA basin. He keeps a worn copy of the California Energy Code on his truck seat.

Our crew knows Rockwool’s density and rigidity require different handling than fiberglass or cellulose - and we have the HEPA recovery equipment to prove it. The 365-Day Done Right Promise applies to every job, backed by a written scope and warranty delivered before work starts. Calls are answered by a live person, 24/7. We also service Reflectix and other radiant barrier systems when rodents have nested behind them. Background-checked, uniformed technicians. No voicemail loops.
