Rockwool Blown-In Insulation Nationwide

Rockwool Blown-In Insulation in New Braunfels: What to Know First

We provide independent Rockwool blown-in insulation service in New Braunfels, typically scheduling within 48 hours and completing most attic jobs in a single day. Most Rockwool blown-in projects in this market run between $1,800 and $3,400 for a standard attic, depending on existing depth, air-sealing needs, and access complexity. We do not start work without a written price, and we do not ask you to call for a quote - we put the number on paper before anyone enters your attic.

This page is for Rockwool product owners in New Braunfels who need blown-in insulation installed, topped up, or corrected after a previous install. That includes Comfortbatt users whose batts have settled and left gaps, homeowners with older Rockwool blown-in that has compressed below labeled R-value, and anyone who received a Rockwool estimate but wants a second opinion on scope or price.

How Rockwool Products Fail - and How We Fix Them

• Comfortbatt R-23 settled below top plate, creating a thermal bridge. Comfortbatt batts in New Braunfels attics often slump in our heat cycles, leaving the top plate of exterior walls exposed. We remove the failed batt, seal the plate with caulk or foam, then blow Rockwool Comfortbatt-compatible loose fill to restore continuous coverage. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
• Rockwool Safe ‘n’ Sound installed in thermal applications where it doesn’t belong. Safe ‘n’ Sound is an acoustic batt, not a thermal insulation product, but we find it in attics regularly because it handles like Comfortbatt. It carries no labeled R-value. We document the misapplication with photos, remove it if it’s blocking needed thermal performance, and replace with proper Rockwool thermal blown-in or batts per the homeowner’s choice.
• Rockwool loose fill compressed by storage traffic or rodent activity. Blown-in Rockwool holds its R-value when left alone, but walking on it or burrowing through it breaks the lofted structure. In New Braunfels, roof rats from the River Road corridor are a recurring issue. We remove contaminated or compressed material, rodent-proof the entry points, and re-blow to specified depth with new Rockwool product.
• Top plates and can lights left unsealed beneath Rockwool insulation. Rockwool is not an air barrier. When previous installers blew or placed Rockwool over unsealed penetrations, conditioned air escapes directly through the insulation. We pull back the Rockwool, seal every top plate, electrical box, and can light with fire-rated foam or caulk, then reinstall the insulation. Our blower-door test quantifies the reduction in CFM50.
• Rockwool batts installed against non-IC-rated recessed lights. Rockwool is non-combustible, but that does not make it safe to pack against fixtures that require clearance for heat dissipation. We find this in older New Braunfels homes with retrofit can lights. We identify non-IC fixtures, maintain required clearances or recommend replacement, and document the condition with photos for the homeowner’s records.

Our Rockwool Blown-In Insulation Process

1. 1
   Call and scope. You call (830) 243-6352 or text. A live person answers. We schedule a site visit, and Wes Okafor or a named technician confirms the appointment with a text when en route - Haven Standard: Arrive on schedule.
2. 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. We photograph existing Rockwool condition, measure settled depth, and identify air leaks at top plates, chases, and penetrations.
3. 3
   Written price before any work starts. We deliver a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1. No exceptions.
4. 4
   Air sealing first, then insulation. We seal all accessible leaks with fire-rated foam, caulk, or rigid blocking. Only after the attic floor is sealed do we add or replace Rockwool blown-in insulation to the depth required for your target R-value.
5. 5
   Post-install blower-door test and photo record. We run the blower-door test again and provide printed pre- and post-job CFM50 readings. You receive a Documented Photo Record of the completed work, including depth measurements and any conditions we observed.
6. 6
   365-Day Done Right Promise. If it’s not done right, we make it right. The written warranty is already in your hand.

What Rockwool Blown-In Insulation Costs in New Braunfels

Homes in the Hill Country fringe of New Braunfels, especially older slab construction off River Road and near the Guadalupe, tend to have higher stack-effect leakage than homeowners expect. That air sealing work adds labor but is non-negotiable in our process - we will not blow insulation over an unsealed attic floor. Bring us any written estimate for a free second opinion; we’ll read it with you. Call (830) 243-6352 for your written price - estimates are free.
