GreenFiber Attic Cleaning & Rodent Proofing in Pasadena: What to Know First
GreenFiber attic cleaning and rodent proofing in Pasadena typically runs between $1,200 and $3,800 depending on attic size, contamination level, and whether we’re doing a full exclusion job or just a cleanup. Most jobs are completed in one to two days. We’re an independent GreenFiber service provider, not an authorized dealer, which means we call it like we see it: we’ll tell you if your GreenFiber insulation can be saved, re-fluffed, or needs to come out entirely.
This page is for Pasadena homeowners who own a home insulated with GreenFiber blown-in cellulose or fiberglass and have noticed rodent activity, odors, or staining on ceilings. If you’re seeing droppings in the attic or hearing scratching overhead at night, call us at (626) 606-2964 and a live person will pick up. We’ve been cleaning and restoring attics in Pasadena since 2000, and we know exactly what GreenFiber looks like when it’s been through a rodent infestation.
How GreenFiber Products Fail - and How We Fix Them
- Rodent tunneling through GreenFiber SANCTUARY cellulose. This is the most common failure we see in Pasadena attics. Rats and mice love loose-fill cellulose because it’s easy to burrow through and it hides them from predators. When rodents tunnel through GreenFiber, they compress it into matted paths, crushing the air pockets that give it R-value. We remove the contaminated material, sanitize the deck, and blow in fresh GreenFiber to restore the original R-value, not just fluff over the damage.
- Urine-saturated GreenFiber losing its fire retardant. GreenFiber products are treated with borates for fire resistance and pest deterrence, but rat urine and feces break down that treatment over time. Once the borate treatment degrades, the cellulose becomes less fire-resistant and less effective at repelling pests. We test suspect areas, bag out the saturated material, and replace it with new borate-treated GreenFiber.
- GreenFiber blown-in fiberglass matting under roof leaks. This one surprises people. Blown fiberglass doesn’t absorb water like cellulose, but Pasadena’s winter rains and occasional roof leaks cause it to mat down and lose loft. Once matted, it never recovers its insulating value on its own. We pull the matted sections, dry the area, and re-blow to the proper depth for your attic’s R-value target.
- GreenFiber settling in older Pasadena homes. Cellulose settles naturally over time, and in homes built before 1990 around Bungalow Heaven and Madison Heights, we often find attics with half the R-value they should have because the GreenFiber has compacted 20 to 30 percent since installation. Rodent activity accelerates this settling. We measure the actual depth, compare it to what your attic needs, and top off or replace as needed.
- Rodent nests built directly into GreenFiber batts. If your attic has GreenFiber batt insulation in the walls or knee walls, rodents will shred the facing and pull fibers into nesting material. We find this a lot in Pasadena’s older Craftsman homes where the attic has been converted or partially finished. We remove the damaged batts, clean the cavities, and re-insulate to match the rest of your attic’s thermal envelope.
Our GreenFiber Attic Cleaning & Rodent Proofing Process
- 1
Call and talk to a person. You call (626) 606-2964, a live person answers, and we schedule a time to come look at your attic. No voicemail, no call center.
- 2
Attic inspection and damage assessment. Our tech walks your attic and maps exactly where GreenFiber is contaminated, matted, or missing. We check for entry points at the same time so we know what we’re dealing with in one visit.
- 3
Upfront price, no surprises. We give you a written quote before any work starts. You’ll know the cost to clean, sanitize, exclude, and re-insulate before we touch a thing.
- 4
Removal and sanitization. We vacuum out contaminated GreenFiber with commercial equipment, then treat the attic deck and framing with an antimicrobial sanitizer that handles rodent waste, urine odors, and bacteria.
- 5
Exclusion and sealing. We seal entry points with steel mesh, foam, and flashing where needed. Rodents will find the same hole twice, so we don’t skip this step.
- 6
Fresh insulation and final check. We blow in new GreenFiber to the proper depth, re-verify R-value, and make sure your attic is clean, dry, and rodent-free. Then we back it all with our Done Right Promise.
What GreenFiber Attic Cleaning & Rodent Proofing Costs in Pasadena
Most Pasadena attics fall into these ranges:
- Basic attic cleanout and sanitizing: $1,200 to $1,900 for attics up to 1,200 square feet with moderate contamination.
- Full rodent exclusion plus cleanup: $2,000 to $3,000 depending on how many entry points need sealing and how much of your roofline needs attention.
- Removal and full GreenFiber replacement: $2,800 to $3,800 for larger attics or heavy contamination where the insulation can’t be saved.
- Top-off after cleaning: $800 to $1,400 to add new GreenFiber to restore R-value where existing insulation is still in good shape.
What moves the price: attic square footage, how long rodents have been active, whether you have blown-in or batt GreenFiber, and how many entry points need work. Call (626) 606-2964 for a free estimate. We’ll give you a real number, not a range guess.
Why Pasadena Homeowners Call Walt’s Insulation for GreenFiber Work
We’ve been doing this since 2000, and we’re the one down the road, not a franchise with an 800 number. Walt Brenner started this company and still runs it. When you call, you get a real person who knows GreenFiber products and knows Pasadena attics, from the 1920s bungalows near the Rose Bowl to the newer builds up in Hastings Ranch. Our background-checked, uniformed techs show up on time and do the job right the first time. If it’s not done right, our Done Right Promise means we make it right. That’s a lifetime workmanship guarantee, not a one-year warranty with fine print. And if your attic has a mix of materials, including Reflectix radiant barrier, we handle that too.
FAQs
No. Professional attic cleaning and re-insulation with GreenFiber products does not void the manufacturer warranty when done correctly. However, if rodents have been in your attic, the warranty may already be compromised by contamination. We can help you document the condition before and after so you have records if you need to file a claim.
It depends on how much contamination you have. Light rodent activity in one corner of the attic often means we can remove just the affected area, sanitize, and top off with fresh GreenFiber. Heavy contamination across the whole attic means full removal and replacement. We’ll show you photos from your attic so you can see exactly what we’re seeing before you decide. Call (626) 606-2964 and we’ll walk you through it.
Most Pasadena jobs can be scheduled within three to five business days. If you have active rodent activity or water intrusion, tell us when you call and we’ll do our best to work you in sooner. A live person answers 24/7, so you can call tonight and we’ll get you on the schedule.
For light to moderate rodent activity, cleaning and sanitizing is almost always cheaper than full replacement. But if your GreenFiber has been saturated with urine for months or years, replacement is often the smarter long-term move because you’re starting fresh with full R-value and fresh pest deterrence treatment. Either way, we’ll give you both options with real numbers and let you decide. Estimates are free, so call (626) 606-2964 and we’ll come look.
We handle both. Cleaning without exclusion means the rodents come right back. We seal entry points, set up exclusion barriers, and then clean and re-insulate so the problem doesn’t repeat. It’s all part of the same job, not an add-on service.
