We provide independent Knauf insulation removal and replacement in New Braunfels, typically completing attic jobs in one to two days with a written price before any work starts. Most removal and replacement projects in the area run between $2,800 and $5,400 depending on attic square footage, contamination level, and whether air sealing is needed first.

This page is for homeowners who know they have Knauf insulation in their attic - whether EcoBatt, Jet Stream, or an older blown-in fiberglass line - and need it removed due to contamination, compression, moisture damage, or rodent activity. We also handle vermiculite and pre-1990s insulation that may contain asbestos, which requires separate abatement protocols before Knauf replacement can begin.
How Knauf Products Fail - and How We Fix Them
- Knauf EcoBatt with ECOSE Technology - binder breakdown in high humidity. The plant-based ECOSE binder performs well in dry climates, but in New Braunfels attics where summer humidity pushes 70% and roof leaks from hail events are common, we’ve seen EcoBatts in River Road and Gruene homes lose dimensional stability after 8-12 years. The batts sag away from top plates and create thermal bypasses. We remove the degraded material, seal the bypasses with caulk and foam, then replace with fresh EcoBatt or an alternative if the homeowner prefers.
- Knauf Jet Stream blown-in fiberglass - settling and compression beyond rated thickness. Jet Stream is marketed for full cavity fill, but in attics where homeowners or prior contractors have used the space for storage, the 1.5-2.0 lbs/ft³ density compresses to half its labeled R-value. We see this in Canyon Lake area homes where attics double as holiday storage. We vacuum out the compacted material, which cannot be fluffed back to spec, and reinstall to proper depth with a depth marker photo in your documented record.
- Knauf Momentum blown-in - dusting and air leakage at chases. Momentum’s fine fiber structure can migrate through unsealed penetrations around chimney chases and duct boots, creating a visible dust layer on horizontal surfaces below. This isn’t a product defect; it’s an installation sequencing error - insulation was blown before air sealing. We remove the migrated material, seal with fire-rated foam and metal flashing where required, then reinstall. The number on the blower-door printout tells you what the insulation did. Everything else is just talk.
- Knauf insulation with rodent contamination - urine saturation and pheromone retention. Fiberglass doesn’t rot, but it does hold rodent urine and the pheromones that attract subsequent infestations. We’ve pulled Knauf batts from New Braunfels attics near the Guadalupe where raccoon and roof rat activity is seasonal. Standard removal isn’t enough; we use HEPA vacuum extraction, apply enzyme treatment to decking, and install baffles and screening before replacement. Without this step, new insulation becomes a fresh nesting site within two seasons.
- Pre-2000 Knauf loose-fill with potential vermiculite cross-contamination. Some New Braunfels homes built during the 1980s oil boom received vermiculite insulation that was later capped with Knauf fiberglass. The vermiculite layer is often invisible until removal begins. We stop work, sample for asbestos, and coordinate with a licensed abatement contractor if positive. This isn’t rare; we’ve encountered it three times in the past two years in homes near I-35 and FM 306.
Our Knauf Insulation Removal & Replacement Process
- 1
On-site assessment and written price. We inspect attic access, measure square footage, identify the Knauf product line, and test for moisture and contamination. You receive a flat price, written scope, and written warranty before anyone lifts a tool - Haven Standard Clause 1.
- 2
Blower-door test (pre-work). We run a pressurization diagnostic to establish your baseline CFM50 - the cubic feet of conditioned air your home leaks per minute at 50 Pascals of pressure. This number guides where we focus air sealing before new insulation goes in.
- 3
Removal and disposal. We use commercial HEPA vacuums with 6-inch hoses to extract old Knauf material without dispersing fibers into living space. Contaminated material is bagged, sealed, and disposed of per Texas Commission on Environmental Quality guidelines.
- 4
Air sealing and prep. Before any replacement insulation touches the attic floor, we seal top plates, can lights, duct penetrations, and chimney chases. In New Braunfels slab homes, stack-effect leakage at the attic floor often accounts for 30-40% of total envelope loss.
- 5
Replacement installation and verification. We install your chosen replacement material - new Knauf, Owens Corning, Johns Manville, Rockwool, or another line from our supplier list - to labeled depth with uniform coverage. A second blower-door test measures the improvement. You receive printed pre- and post-job numbers, plus a Documented Photo Record of the completed work.
- 6
Cleanup and 365-Day Done Right Promise activation. We remove protective sheeting, HEPA-vacuum the work path, and leave your documented record and warranty in hand. If anything isn’t right, we make it right.

FAQs
No - Knauf’s limited warranty on installed insulation does not extend to removal by an independent service provider, and there is no manufacturer authorization required for removal work. As an independent Knauf service provider, we document the original product line and installation condition in your photo record, which can be useful if you have a separate contractor workmanship warranty claim. Call (830) 243-6352 if you’d like us to review what coverage might still apply.
We can source current Knauf lines including EcoBatt and Jet Stream through our supplier network, or we can install Owens Corning, Johns Manville, Rockwool, or another material if you prefer different performance characteristics. We don’t push proprietary products. The choice is documented in your written scope before work begins.
If the material is compressed, contaminated, or has migrated from its original position, removal is necessary - topping off traps the problem beneath new layers. If it’s simply settled evenly and remains clean, we may recommend adding to achieve proper depth. We determine this during the on-site assessment and show you photos of what we found before quoting either approach.
Most standard jobs are completed in one to two days. Contaminated removals requiring enzyme treatment or decking repair may extend to three days. We schedule based on your availability, not manufactured urgency, and we text when your technician is en route under Haven Standard: Arrive on schedule.
Spot repairs are rarely cost-effective for attic insulation because thermal bridging at the repair boundaries undermines the R-value you’re paying for. In nearly every New Braunfels attic we’ve assessed, full removal and replacement with proper air sealing first delivers lower lifetime cost and better blower-door results. We’ll show you both numbers and let you decide. Call (830) 243-6352 for a free estimate - written price before any work starts.
