Rockwool Insulation Removal & Replacement in New Braunfels: What to Know First
We provide independent Rockwool insulation removal and replacement in New Braunfels, with most residential jobs completed in one to two days after our initial assessment. As an independent Rockwool service provider, we are not affiliated with or authorized by Rockwool, but we stock and install the full Comfortbatt, Safe’n’Sound, and AFB product lines along with compatible alternatives. Most attic insulation removal and replacement jobs in a New Braunfels home this size run between $2,800 and $5,400, depending on contamination level, attic square footage, and whether air sealing is needed first. We publish a written price before any work starts, and we do not begin until you have that number in hand. If you own a home in New Braunfels with Rockwool insulation that has settled, gotten wet, or been compromised by rodents or vermiculite contamination, this page covers what failure looks like, what fixing it costs, and what documentation you’ll walk away with. Call (830) 243-6352 for a free estimate.
How Rockwool Products Fail - and How We Fix Them
- Comfortbatt R-23 settled below top plate level in 2×6 walls. The batts compress over time in New Braunfels homes built during the 2015-2020 construction boom, especially in Canyon Lake area subdivisions where seasonal humidity swings exceed 40%. We remove the settled material, air seal the top plates and electrical penetrations with acoustical sealant, then reinstall to full loft with new Comfortbatt or dense-pack alternative.
- Safe’n’Sound in interior partition walls absorbs roof leak water without visible exterior damage. The stone wool resists mold better than fiberglass, but the paper facing and wood studs behind it do not. We find this in older homes off Seguin Avenue near the original Guadalupe crossing, where roof penetrations from previous HVAC retrofits went unsealed. We remove affected batts, treat the stud bay with antimicrobial, and replace with fresh material after the roof leak source is fixed.
- AFB (Acoustical Fire Batt) in commercial retrofits disintegrates at the facing adhesive when attic temperatures exceed 145°F. New Braunfels attics hit this regularly in July and August. The batt separates from its Kraft paper or foil facing and sags into soffit vents, blocking intake airflow. We remove the failed material, install proper baffles, and replace with AFB or switch to unfaced Comfortbatt if fire rating allows.
- Rockwool installed over unsealed can lights and top plates creates a thermal bypass that negates the R-value. The insulation itself is fine; the installation skipped the hard part. We see this in River Road corridor slab homes where stack effect pulls conditioned air straight through the attic floor. We remove or work around existing Rockwool, seal every penetration with fire-rated foam and caulk, then reinstall or replace the insulation. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- Vermiculite contamination mixed with older Rockwool in pre-1990 attics. The Zonolite vermiculite mine in Libby, Montana, shipped material nationwide, and we have found it in New Braunfels homes near downtown and along the original IH-35 frontage. Rockwool batts laid over vermiculite do not seal asbestos fibers; they hide them. We follow Texas Department of State Health Services guidelines for asbestos-containing material assessment, use HEPA containment during removal, and replace with new Rockwool or alternative only after clearance.
Our Rockwool Insulation Removal & Replacement Process
- 1
Call and scheduling. A live person answers 24/7. We book a 2-hour arrival window and text you when the technician is en route.
- 2
Attic inspection and blower-door test. We run a blower-door test - a pressurization diagnostic that measures how many cubic feet of conditioned air your house leaks per minute - to establish a baseline CFM50 reading. We photograph existing Rockwool condition, measure settled depth, and identify contamination sources.
- 3
Written price and scope. You receive a flat price, written scope, and written warranty before anyone lifts a tool. This is Haven Standard Clause 1. No exceptions.
- 4
Air sealing first, then removal. We seal top plates, can lights, plumbing and electrical penetrations, and chimney chases with fire-rated materials. Only after the attic floor is sealed do we begin removal.
- 5
Removal, cleaning, and replacement. We bag and remove failed or contaminated Rockwool, HEPA-vacuum the attic deck, install baffles at soffits, then place new Rockwool or your chosen alternative to specified R-value and depth.
- 6
Post-job blower-door test and documentation. We run the blower-door again, print pre- and post-job CFM50 readings, and deliver your Documented Photo Record. You leave with numbers, not promises.
Before
AfterWhat Rockwool Insulation Removal & Replacement Costs in New Braunfels
| Scenario | Typical Range |
|---|---|
| Standard attic removal and replacement (1,200-1,800 sq ft), no contamination | $2,800 - $4,200 |
| Contaminated insulation removal (rodent, mold, or water damage) | $3,600 - $5,400 |

What moves the price: attic square footage, ease of access (scuttle vs. pull-down stairs vs. cut new opening), contamination level requiring HEPA containment, whether vermiculite testing is needed, and whether the home has active roof leaks that must be repaired first. We also service Reflectix and other insulation brands if your project involves mixed materials or you prefer to switch systems.

Why New Braunfels Homeowners Call Topside Attic Insulation New Braunfels for Rockwool Work
Wes Okafor and our crew have worked neighborhoods all over the New Braunfels area, including jobs off the River Road corridor near the Guadalupe, where stack-effect air leakage in older slab homes tends to run higher than homeowners expect. We have sealed and insulated more than 9,000 homes since 2016, every one with a written price before work started and a documented record when the crew left. Our 365-Day Done Right Promise means if it is not done right, we make it right. We source Rockwool, Owens Corning, Johns Manville, Knauf, CertainTeed, Icynene, Demilec, and GreenFiber - no proprietary lock-in, so you get the material that fits your home, not our supplier agreement. Every technician is background-checked and uniformed. You get a named technician, a text when they are on the way, and printed blower-door numbers when they leave. That is the Haven Standard.
FAQs
Rockwool’s limited warranty covers product defect, not installation or removal by third parties. As an independent Rockwool service provider, we document the condition of existing material with photos before removal, so if a product defect is discovered, you have evidence for a claim. Call (830) 243-6352 and we will walk you through what documentation to keep.
We stock Comfortbatt, Safe’n’Sound, and AFB in common R-values at our New Braunfels warehouse, so most residential replacements start within 48 hours of estimate approval. Specialty commercial densities or fire-rated assemblies may add two to three days. We will tell you exactly which product line we have in stock when we deliver your written price.
Spot repair is rarely cost-effective for attic batts. Once Rockwool has been disturbed, compressed, or contaminated, the thermal or acoustical performance is compromised in ways that are hard to isolate. In most New Braunfels attics we inspect, full removal and replacement with proper air sealing delivers a lower lifetime cost than patching. We will show you both numbers in your written estimate so you can decide.
Most residential jobs are completed in one to two working days after estimate approval. Contaminated material requiring HEPA containment, or vermiculite-coordinated removal, typically runs three to five days including clearance testing. We do not promise same-day completion because we do not skip the air sealing step; a crew that blows new insulation over an unsealed attic floor is leaving you with a hidden bypass that costs money every month.
We are independent and multi-brand. We install Rockwool, Reflectix, Owens Corning, Johns Manville, Knauf, and others. If your Rockwool has failed prematurely and you want to discuss alternatives, we will quote compatible options with the same written price and scope format. No proprietary lock-in.
