GreenFiber Attic Cleaning & Rodent Proofing Nationwide

GreenFiber Attic Cleaning & Rodent Proofing in Los Angeles: What to Know First

GreenFiber attic cleaning and rodent proofing in Los Angeles typically runs $1,200 to $3,800 depending on attic size, contamination level, and whether we’re doing a full sanitization or a targeted exclusion job. Most GreenFiber jobs in L.A. are completed in one visit, often same-day for straightforward cleanouts. We’re an independent GreenFiber service provider, which means we work on your insulation exactly as we’d work on any top-tier cellulose product, with no warranty conflicts and no finger-pointing. If you own a Los Angeles home with GreenFiber insulation and you’ve heard scratching, smelled something dead, or found droppings near your attic hatch, this page tells you exactly what we’ll do about it.

How GreenFiber Products Fail - and How We Fix Them

• Rodent nesting in loose-fill cellulose (GreenFiber Sanctuary and GreenFiber Cellulose Blown-In). Cellulose is ground paper treated with borates. Rodents love tunneling through it. In Los Angeles attics, we routinely find rat runs carved through GreenFiber Sanctuary like little highways. The fix is full removal of the contaminated material, sanitizing the deck, and installing fresh GreenFiber or another cellulose product. Patching over rodent-compromised insulation doesn’t work, the scent markers stay and new rodents follow.
• Borate treatment degradation after water exposure. GreenFiber’s fire and pest resistance comes from its borate treatment. When a roof leak or condensation soaks the material, borates leach out and the insulation’s pest-deterrent properties weaken. L.A. homes with older shake roofs or poorly flashed vents see this often. We pull the affected GreenFiber, find and seal the moisture source, and blow in new material.
• Compression and settling in GreenFiber blown-in applications. GreenFiber cellulose settles over time, especially in attics where someone walked through it or where rodents have tunneled. Settled cellulose loses R-value and creates bare spots at the eaves. Our crews identify settlement patterns specific to GreenFiber’s density and re-fluff or top off the layer to restore rated performance.
• Air-gap bypass at the attic floor. GreenFiber does its job when it sits flush against the ceiling drywall. In many Los Angeles homes we see gaps around recessed lights, bath fans, and plumbing chases where rodents and air both get through. Rodent proofing a GreenFiber attic means sealing those penetrations with metal mesh and foam before the insulation goes back in. Insulation alone never stops rodents.
• Dust and particulate spread during rodent activity. When rats or mice tunnel through GreenFiber, they pulverize the cellulose and spread fine dust through wall cavities and down into living spaces. Homeowners report allergy flare-ups and a persistent musty smell. Our cleaning process includes HEPA vacuuming of the attic floor, joist bays, and any ducts accessible from the attic, followed by antimicrobial fogging where contamination warrants it.

Our GreenFiber Attic Cleaning & Rodent Proofing Process

Here’s how a typical GreenFiber attic job goes from first call to final walkthrough:

1. 1
   We answer your call live and ask the right questions. You tell us what you’re hearing, seeing, or smelling. We’ll ask about your attic access, approximate square footage, and any known roof leaks. Neil Ashford trained our team to diagnose by phone before we ever roll a truck.
2. 2
   On-site inspection and honest diagnosis. A background-checked, uniformed tech inspects the attic: insulation depth, rodent entry points, moisture signs, and the condition of your GreenFiber. We show you photos of what we find and explain what actually needs doing, even if it’s less work than you expected.
3. 3
   Upfront pricing before any work starts. You’ll get a line-item quote covering removal, sanitization, exclusion sealing, and new insulation. No surprises, no add-ons mid-job. If your GreenFiber is salvageable, we tell you that too and price the job accordingly.
4. 4
   Cleanout and sanitization. We remove contaminated GreenFiber with commercial vacuums, sanitize the deck and joist bays, and treat for odor and bacteria. Every tech wears proper PPE and contains dust so it doesn’t migrate into your home.
5. 5
   Rodent proofing and exclusion. We seal entry points with galvanized steel mesh, hardware cloth, and professional-grade foam. Common L.A. entries include gable vents, eave gaps, roof-to-wall transitions, and plumbing stacks. This is the part that keeps rodents from coming back.
6. 6
   Fresh insulation and final test. We blow in new GreenFiber cellulose or another product if you prefer, restore proper depth, and walk you through the finished attic. Every job is backed by our 90-Day Done Right Promise: if it’s not right, we make it right.

What GreenFiber Attic Cleaning & Rodent Proofing Costs in Los Angeles

Price moves with attic square footage, how long rodents have been active, and whether your roof deck needs spot repairs before new insulation goes in. A 1,200-square-foot attic with light contamination lands on the lower end; a 2,500-square-foot attic with years of rat activity and water-damaged decking lands higher. Call (213) 782-8141 for a free estimate and an exact number, not a guess. We also honor $50 Off Any Repair Over $250, an $89 Seasonal Tune-Up, and a permanent 5% Senior & Veteran discount.
