How GreenFiber Products Fail - and How We Fix Them

We’ve been in West Hollywood attics since 2000, and GreenFiber insulation has some failure patterns we see over and over. Here’s what actually happens up there:

• Cellulose settles and compresses into rodent highways. GreenFiber’s blown-in cellulose, including their SANCTUARY and InsulSmart lines, settles over time. Rats and mice burrow through the settled layers, creating tunnels that crush the insulation’s loft and destroy its R-value. We remove the contaminated material, treat the space, and blow in fresh insulation only after exclusion is complete.
• Moisture turns GreenFiber into a mat. GreenFiber is treated with borates for fire and pest resistance, but it still absorbs moisture like a sponge. In West Hollywood, where marine layer mornings push humidity into attics with poor ventilation, damp cellulose clumps together and loses its thermal performance. When we clean out a GreenFiber attic, we check the ventilation first because no new insulation will survive in a wet attic.
• Rodent urine saturates the cellulose and the borate treatment can’t hide it. The boric acid in GreenFiber deters some pests, but it doesn’t stop rats and mice from nesting in it. Once urine soaks into the material, the smell lingers and air sealing becomes critical. We remove the contaminated insulation down to the decking, sanitize the entire attic, and apply an enzyme treatment before anything new goes in.
• GreenFiber’s dense-pack wall applications hide rodent entry points. In some older West Hollywood buildings near Santa Monica Boulevard, GreenFiber was dense-packed into wall cavities during remodels. Rodents chew through the drywall from inside the wall and the insulation actually gives them a nesting medium. We find those wall-cavity entry points and seal them from the attic side before they become a recurring problem.
• Old GreenFiber installs in West Hollywood often lack proper baffles. Many attics we service had GreenFiber blown in years ago without adequate eave baffles. The insulation blocks soffit vents, the attic stops breathing, and moisture builds up. During a cleanout we correct the baffle situation so the new insulation performs the way it should.

Our GreenFiber Attic Cleaning & Rodent Proofing Process

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

1. 1
   You call, we show up. We answer live, 24/7. We schedule a time that works, and we arrive in uniform with a background-checked crew. No window-waiting, no no-shows.
2. 2
   We inspect the whole attic, not just the mess. We look for rodent entry points, moisture sources, ventilation issues, and the condition of your GreenFiber. We photograph everything so you see what we see.
3. 3
   We give you a written, itemized price. Before any work starts, you know the exact cost. We don’t do vague quotes or surprise add-ons. If you’ve already got a written estimate from someone else, bring it to us. We’ll give you a free second opinion.
4. 4
   We remove and haul out the contaminated GreenFiber. Full extraction down to the decking using HEPA-filtered vacuums. We don’t leave old, urine-soaked material sitting in your attic. It gets bagged and removed from your property.
5. 5
   We sanitize and decontaminate. The entire attic gets treated for bacteria, odor, and any lingering pests. Then we seal every rodent entry point we found: gaps around pipes, vents, electrical penetrations, and roofline openings.
6. 6
   We test, you approve, we stand behind it. We walk you through the finished attic, show you the sealed entry points, and answer any questions. Every job carries our Done Right Promise. If it’s not done right, we come back and make it right. No runaround.

As an independent GreenFiber service provider, we’re not affiliated with the manufacturer. That means we don’t answer to a corporate script. We answer to you, and we answer for the work. Walt Brenner has been the one making sure of that since 2000.

What GreenFiber Attic Cleaning & Rodent Proofing Costs in West Hollywood

Here’s the honest pricing picture for West Hollywood homes:

• Basic GreenFiber attic cleanout: $1,200 to $2,800 depending on attic square footage and depth of the insulation
• Full sanitation and decontamination: $400 to $900 on top of the cleanout, depending on the extent of the rodent activity
• Rodent proofing and exclusion: $600 to $1,800 depending on how many entry points we find and how accessible they are
• Attic restoration with new blown-in insulation: $2,500 to $6,000 for a typical West Hollywood single-family home, materials and labor included

What moves the price: attic accessibility (older West Hollywood buildings have tight access hatches), how long the infestation has been active, and whether we’re dealing with one species or two. We work with Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber, so if you want to switch brands after the cleanout, we’ve got options.
