Rockwool Insulation Removal & Replacement Nationwide

Rockwool Insulation Removal & Replacement in Boerne: What to Know First

We provide independent Rockwool insulation removal & replacement in Boerne, with most attic jobs completed in one day and a written price delivered before any work starts. Typical turnaround from inspection to completion runs 24-72 hours, and we publish before-and-after blower-door numbers on every job so you can verify the result in pascals, not promises. This page is for Boerne homeowners who have Rockwool Comfortbatt, Comfortboard, or AFB (Acoustical Fire Batt) insulation that needs removal due to contamination, moisture damage, or failed retrofit work - and who want a contractor who will seal the envelope first, then fill it. Call (830) 529-7780 for a free estimate with a written scope.

How Rockwool Products Fail - and How We Fix Them

• Comfortbatt R-23 wall cavities with compressed edges. We see this in Boerne’s 2015-2020 builds near the Cibolo Nature Center, where framers stuffed full-width batts into 2×6 studs without splitting for wiring. Compressed mineral wool loses 15-25% of its labeled R-value because trapped air pockets collapse. We remove the compressed batts, air-seal the top plates and electrical penetrations with fire-rated caulk, then reinstall to full loft with proper relief cuts around obstructions.
• Comfortboard 80 under slab or on exterior foundation walls with improper drainage. Rockwool’s rigid board is hydrophobic - it won’t wick liquid water - but in Boerne’s Hill Country clay, hydrostatic pressure can force water through foundation cracks and deposit silt behind the board. The board itself stays intact, but the thermal bridge at the crack negates the insulation value. We remove the compromised sections, remediate the drainage path, and reinstall with a capillary break detail that accounts for our seasonal wet-dry cycles.
• AFB (Acoustical Fire Batt) in commercial retrofits with missing firestopping. AFB is tested as a system, not a standalone product. When we remove it in Boerne office conversions, we often find the perimeter firestopping sealant was omitted or the wrong ASTM rating was used. We replace the AFB with matching density and reinstall proper firestopping at all membrane penetrations, documented with photos for the building inspector.
• Rockwool blown-in attic insulation with settled top coat. Some Boerne contractors have blown loose-fill mineral wool over unsealed attic floors, where stack-effect air leakage - warm air rising in winter, reverse in summer - carries fine particles out of the insulation matrix. The remaining material reads full depth but has lost effective coverage at the eaves. We vacuum out the degraded layer, seal all top plates and can lights with fire-rated foam, then reinstall to a uniform density with marked depth gauges.
• Comfortbatt in metal stud walls with thermal bridging at every stud. Rockwool performs well in steel framing only when the cavity is fully filled and continuous insulation breaks the stud line. We’ve removed failed installations in Boerne’s newer commercial strips where 3.5-inch batts were used in 6-inch studs, leaving a 2.5-inch air gap that convection loops through. We replace with full-depth Comfortbatt and add a continuous insulation layer where the budget allows, with the pressure-differential report to prove the improvement.

Our Rockwool Insulation Removal & Replacement Process

1. 1
   Inspection and blower-door baseline. We run a pressurization test - a blower-door reading that shows, in one number, how much air your building envelope is losing. Wes Okafor pulls his ACCA Manual J off the truck if the homeowner wants to understand the load calculation behind our recommendations.
2. 2
   Written price and scope. Under Haven Standard Clause 1, you get a flat price, written scope, and written warranty before anyone lifts a tool. No exceptions.
3. 3
   Air sealing before insulation touch. We seal top plates, can lights, plumbing penetrations, and chimney chases with fire-rated materials appropriate to Rockwool’s mineral composition. Seal the envelope first. Then fill it.
4. 4
   Removal and disposal. We vacuum out contaminated or failed Rockwool with HEPA-contained equipment, bag to local disposal requirements, and photo-document the exposed cavity condition.
5. 5
   Replacement and density verification. New Rockwool or alternative material is installed to manufacturer spec with depth gauges or density checks, depending on product type.
6. 6
   Final blower-door test and documentation. We run the pressurization test again, print the pressure-differential report in pascals, and add it to your Documented Photo Record before we leave.

What Rockwool Insulation Removal & Replacement Costs in Boerne

Most Rockwool insulation removal & replacement jobs in Boerne run between $2,800 and $6,500 for residential attic work, and $1,800 to $4,200 for single-wall or crawl space projects. What moves the price: whether hazardous material testing is required (vermiculite intermingling is common in pre-1990 Boerne homes), the accessibility of the cavity, and whether air sealing can be completed from the interior or requires soffit work. Commercial AFB replacement with firestopping documentation runs $4,500-$9,000 depending on square footage and permit complexity. We also service Reflectix products if your system uses hybrid insulation. Every estimate is free, every price is written, and we offer a Free Second Opinion on any competing written quote.
