GreenFiber Insulation Removal & Replacement in New Braunfels: What to Know First
We provide independent GreenFiber insulation removal and replacement in New Braunfels, with most jobs completed in one day and a written price delivered before any work starts. As an independent GreenFiber service provider, we are not affiliated with or authorized by GreenFiber, but we stock the product lines and handle the failure modes that show up repeatedly in Comal County homes. Typical turnaround from call to completion is 24 to 48 hours for standard jobs; contaminated or extensive removals may run longer. If you own a GreenFiber-insulated home in New Braunfels and are dealing with settled, compressed, or moisture-damaged material, call (830) 243-6352. We will read your situation, give you a flat written price, and schedule the work.
How GreenFiber Products Fail - and How We Fix Them
- GreenFiber All Borate cellulose settling below labeled R-value in attic floors. Blown-in cellulose, especially the All Borate line installed in New Braunfels homes between 2010 and 2018, settles 15 to 20 percent in the first three years. The bag calls for 10.25 inches for R-38; we regularly find 7 inches in River Road corridor attics where summer attic temps exceed 140°F and accelerate compaction. Our fix: remove to substrate, air-seal top plates and can-light penetrations, then reinstall to manufacturer-settled depth with a depth marker photo in your record.
- GreenFiber Sanctuary two-part pour-in system bridging in irregular joist cavities. The Sanctuary line, marketed for wall and slope applications, forms bridges over obstructions in older New Braunfels homes with hand-cut rafter bays and mixed 16- and 24-inch centers. Bridging leaves thermal voids that read hot on infrared. We remove the bridged material, dense-pack to 3.5 pounds per cubic foot with a proper fill tube, and verify with cavity-probe density checks.
- GreenFiber Low Dust formula absorbing roof-leak moisture and losing borate fire retardant. The Low Dust line uses a proprietary oil treatment for installer comfort, but that treatment can trap moisture when roof leaks occur during New Braunfels spring storm season. Borate leaches out, fire resistance drops, and mold colonizes the paper fibers. We remove to deck, treat substrate with borate-based fungicide, and replace with fresh material only after the roof leak is documented fixed.
- GreenFiber stabilized cellulose in vented crawl spaces wicking ground moisture. Stabilized cellulose, common in 2015-2020 New Braunfels slab homes with vented crawl spaces, wicks humidity through the kraft facing when crawl vents are left open during August dew points above 75°F. The material cakes and delaminates. We remove the caked material, install a proper vapor barrier if absent, and replace with a product suited to the actual crawl environment.
- GreenFiber loose-fill in can-light contact applications creating heat traps. Pre-2012 installations in New Braunfels often blew loose-fill directly against non-IC-rated can lights. The cellulose chars around the housing, creating a hard, shrunken collar that is itself a fire risk. We remove the charred collar, verify or upgrade to IC-rated housings, air-seal the penetration with fire-rated foam, and reinstall with proper baffles.
Our GreenFiber Insulation Removal & Replacement Process

- 1
Call and scope. A live person answers 24/7. We ask about the GreenFiber product line if you know it, the home’s age, and what you’re seeing. We schedule a site visit, not a sales call.
- 2
On-site diagnostic and written price. We inspect the attic or crawl space, identify the GreenFiber line, measure settled depth, and run a blower-door test if air sealing is in scope. You get a flat written price before any work starts. Haven Standard Clause 1.
- 3
Removal and substrate prep. We vacuum to substrate with HEPA-contained removal equipment, bag the material, and inspect for air leaks, moisture damage, or rodent evidence. Photos at every stage go in your Documented Photo Record.
- 4
Air sealing first, always. Top plates, wire penetrations, can lights, chimney chases, and duct boots get sealed before any new insulation touches the space. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- 5
Replacement and verification. We install replacement material to labeled depth with density verification where required. On applicable jobs, we run a post-work blower-door test and deliver printed pre- and post-job CFM50 readings.
- 6
Cleanup, documentation, and 365-Day Done Right Promise. You receive the written scope, photo record, blower-door numbers if applicable, and warranty documentation before the crew leaves.

Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for GreenFiber Work

We have removed and replaced GreenFiber products in New Braunfels homes since 2016, and we know the specific failure patterns of each line. Wes Okafor and our crew have worked attics off River Road near the Guadalupe, in the older slab homes where stack-effect leakage runs higher than owners expect, and in the newer subdivisions where settling All Borate is the common complaint. We do not sell insulation over unsealed air leaks. Every applicable job gets before-and-after blower-door numbers. Our materials come from GreenFiber, Owens Corning, Johns Manville, Knauf, Rockwool, and others, so we match the product to the condition, not the other way around. We also service Reflectix radiant barrier systems when those are part of the same envelope. Calls are answered by a live person, 24/7, and our 365-Day Done Right Promise is in writing before anyone lifts a tool.
FAQs
GreenFiber’s limited warranty covers product defect, not installation or subsequent modification by an independent service provider. As an independent GreenFiber service provider, our work does not carry GreenFiber’s backing, but our 365-Day Done Right Promise and written warranty apply to everything we install. Call (830) 243-6352 and we will read your original warranty language with you.
We source GreenFiber All Borate, Sanctuary, and Low Dust direct from authorized distributors. If a GreenFiber line is back-ordered, we will quote an equivalent cellulose from Johns Manville or Knauf with matched R-value and borate treatment, and we will document the substitution in your written scope before you approve it.
If the existing GreenFiber is dry, uncontaminated, and has not settled below 50 percent of labeled depth, topping off can work. If it is compressed, moisture-damaged, borate-depleted, or rodent-affected, removal is the only sound option. We will show you the cavity probe and photo evidence during the site visit so you can decide from fact, not pressure.
Most standard attic jobs are completed in one working day. Contaminated removals requiring substrate treatment, or jobs with extensive air sealing, may run two days. We schedule within 24 to 48 hours of written price approval. Call (830) 243-6352 for current availability.
Any cellulose product, GreenFiber included, performs poorly when installed against active leaks or in unsealed vented crawl spaces during our humid season. The difference is not the brand; it is whether the building envelope was properly sealed and ventilated before installation. We test and seal first, then insulate, which is why our jobs do not come back with moisture callbacks.
