GreenFiber Insulation Removal & Replacement in San Antonio: What to Know First
GreenFiber insulation removal and replacement in San Antonio typically runs $1.50 to $3.50 per square foot depending on attic access, contamination level, and how much material needs to come out. Most full attic removals take one to two days, and we’re usually out for a quote within 24 hours of your call. As an independent GreenFiber service provider, we don’t sell you a brand, we fix what’s failing and put in what actually works for South Texas heat. If you’re seeing settling, moisture damage, or rodent activity in your GreenFiber insulation, call (866) 751-4428 and we’ll talk through what’s going on before you spend a dime.

How GreenFiber Products Fail - and How We Fix Them
GreenFiber makes good cellulose insulation, but no insulation product survives San Antonio attics without eventually needing attention. Here’s what we actually see in the field, based on the specific GreenFiber products installed across Bexar County homes over the last 25 years.
- Sanctuary by GreenFiber settles hard in high-humidity attics. The Sanctuary line is treated for pest resistance, but San Antonio’s July humidity plus attic temperatures over 140 degrees cause it to compact faster than you’d expect. We regularly pull San Antonio attics where Sanctuary has dropped from R-38 to R-19 or worse in eight years. The fix is full removal and replacement with a product matched to the attic’s ventilation, not just topping it off.
- GreenFiber Cellulose Insulation (the standard blown-in line) soaks up moisture from roof leaks and AC condensation. Cellulose is recycled paper treated with borates, which means it holds water. A slow roof leak no one notices can saturate a two-foot section of GreenFiber before you see a ceiling stain. Wet cellulose loses R-value fast and becomes a mold risk. We remove the affected area, dry the space, and replace with new material once the leak source is fixed.
- Rodent activity ruins GreenFiber faster than fiberglass. Rats and mice in San Antonio attics burrow through loose cellulose, leaving tunnels, nesting pockets, and droppings throughout the material. GreenFiber’s texture makes it easy for them to move through. This calls for full removal, sanitation, and air sealing before any new insulation goes in.
- GreenFiber Stabilized Cellulose in wall cavities can slump if it wasn’t dense-packed correctly. When installers blow it too loose, you get voids at the top of wall cavities within a few years. In San Antonio, those voids show up as rooms that won’t hold temperature in summer. We extract the under-packed material and dense-pack the cavity properly.
- GreenFiber’s Cocoon line, often installed in older San Antonio homes, wasn’t always installed at the right density. Older homes around Alamo Heights and Monte Vista frequently have Cocoon insulation blown decades ago at inconsistent density. We find packed-down sections under attic walkways and completely empty spots in corners. The fix is full removal, air sealing, and a fresh, consistent install.
Our GreenFiber Insulation Removal & Replacement Process
Every GreenFiber removal job in San Antonio follows the same steps, whether it’s a 1950s house in Jefferson or a newer build in Stone Oak.
- 1
Call and talk to a person. You reach someone at (866) 751-4428 who knows insulation, not a call center. We ask about what you’re seeing, set a time to take a look, and show up when we say we will. No trip charge inside the service county.
- 2
The inspection. We check attic access, measure current insulation depth and density, look for moisture, rodent sign, and settling patterns specific to the GreenFiber product you have. You get photos and a straight explanation of what’s actually wrong.
- 3
The honest recommendation. Sometimes removal isn’t necessary, sometimes it’s the only option. Either way, you get upfront pricing without games. We’ll tell you if a cheaper fix gets the job done safely.
- 4
The removal. We use commercial-grade vacuum extraction to pull out old GreenFiber insulation without spreading dust through the house. Technicians seal off the work area and wear full protective gear. It’s typically done in one day for most attics.
- 5
Prep and replacement. Once the old material is out, we address what caused the failure: leaks, condensation, rodent entry points, poor ventilation. Then we blow in the new insulation at the correct density for your space and San Antonio’s climate.
- 6
The test and the guarantee. We verify coverage and R-value before we call it done. Then our lifetime Done Right Promise kicks in. If it’s not right, we make it right. That’s the whole warranty.

What moves the price: attic height and access, how much material needs to come out, contamination level, and whether air sealing or rodent proofing is part of the job.

Why San Antonio Homeowners Call Walt’s Insulation for GreenFiber Work
We’ve been at this since 2000, and we’ve been in San Antonio even longer. This is a locally owned, owner-operated business with a published address and a license number you can actually look up. Walt Brenner started this company because he got tired of watching homeowners get sold insulation that couldn’t handle a Texas summer, and that hasn’t changed. When you call about GreenFiber removal, you’re talking to people who know the product, know the climate, and know when it’s worth saving versus replacing. We work with GreenFiber and other brands like Owens Corning, Rockwool, Johns Manville, and Reflectix, so we’re not married to one manufacturer’s product. The recommendation you get is based on your house, not our inventory. And every job carries the Done Right Promise: if it’s not done right, we come back and make it right, permanently.
FAQs
If your GreenFiber insulation has settled but is otherwise dry and clean, topping it off is usually cheaper than full removal. If there’s moisture, rodent contamination, or it’s compressed below half its original R-value, removal and replacement typically costs less over the long run because you’re fixing the problem instead of covering it. Call (866) 751-4428 and we’ll give you an honest read on which one your attic needs.
In most cases we can schedule removal within 24 to 48 hours of the inspection, and many standard attic removals are finished in a single day. Emergency situations like water-saturated insulation from a roof leak move to the front of the line. Call us at (866) 751-4428 and we’ll tell you exactly when we can be there.
GreenFiber’s product warranty generally covers manufacturing defects, not installation issues, moisture damage, or settling from San Antonio’s heat. Removing the insulation doesn’t void anything you’d realistically claim against. If the product failed because it was installed wrong, we can document that for you so you’re dealing with facts, not marketing. As an independent GreenFiber service provider, we’re not here to protect a warranty, we’re here to fix your attic.
GreenFiber cellulose is made from recycled paper treated with fire retardant, while fiberglass like Owens Corning is spun glass. In San Antonio’s humid climate, cellulose holds moisture longer and settles more dramatically. That doesn’t mean cellulose is bad, it means the installation density and attic ventilation matter more. We’ll recommend the right product for your specific attic conditions, not whichever brand has the best rebate this month.
Vermiculite removal requires specialized handling because some pre-1990 vermiculite contained asbestos. If we find vermiculite mixed with your GreenFiber insulation during inspection, we’ll discuss testing and removal options before touching anything. Safety protocols on contaminated material are non-negotiable, and you’ll know exactly what the process looks like before we start. Call (866) 751-4428 and we’ll talk through what’s in your attic.
