Owens Corning Insulation Removal & Replacement in Seguin: What to Know First
We provide independent Owens Corning insulation removal and replacement in Seguin, typically completing most attic jobs in one day with a written price locked before any work starts. Most homeowners with Owens Corning PINK Fiberglas or EcoTouch systems in Seguin’s 78155 and 78156 ZIP codes are looking at $2,400-$4,800 for full removal and replacement, depending on attic square footage and whether air sealing is needed first. This page is for Owens Corning owners who’ve found compressed, contaminated, or underperforming insulation and want a crew that documents blower-door numbers, not just promises. Call (830) 549-6646 for a free estimate with a written scope.
How Owens Corning Products Fail - and How We Fix Them
- PINK Fiberglas Loosefill (L77, M77) settles below labeled R-value in Seguin’s heat. The Hill Country’s 100°F-plus summer days accelerate thermal degradation in attics that vent poorly. We’ve measured original L77 in Seguin homes near Guadalupe Regional Medical Center that settled from R-38 to effective R-22 in under 12 years. We remove the compacted material, seal top plates and can-light penetrations, then reinstall to true depth with fresh blown-in Fiberglas or cellulose.
- EcoTouch batts delaminate where roof leaks or condensation saturate the kraft facing. Owens Corning’s recycled-content batts lose structural integrity when the paper facing wicks moisture; the fiberglass core doesn’t rot, but it mats into useless sheets. In Seguin’s spring storm season, we find this pattern in homes with ridge vent gaps or bathroom fans vented into attics. We remove saturated batts, treat for mold if the sheathing’s affected, then replace with un-faced batts or blown-in after sealing the moisture source.
- AttiCat blown-in system creates uneven coverage when installed too fast. The AttiCat machine’s high-velocity hose can shoot Fiberglas past eaves or pile it against hatch openings, leaving cold spots. We’ve re-blown attics in Seguin’s older ranch-style homes where the original installer raced to finish. We remove the lumpy distribution, smooth the deck, then reinstall with even depth markers and baffles at every soffit vent.
- Vermiculite insulation with Owens Corning branding requires abatement protocol. Some Seguin homes built 1960-1984 have vermiculite that was distributed through Owens Corning channels; even if the bags are gone, the loose gray-brown pebbles remain a hazard. We coordinate with Texas-licensed abatement contractors for safe removal, then replace with modern Fiberglas or mineral wool after full deck cleaning and sealing.
- Radiant barrier OSB sheathing (PinkShield, early 2000s) traps moisture when paired with inadequate venting. Owens Corning’s foil-faced roof decking was marketed as a stand-alone solution, but in Seguin’s humid shoulder seasons it can create condensation pockets without proper intake and exhaust airflow. We remove compromised sections, improve ventilation with continuous soffit and ridge vents, then supplement with proper attic insulation rather than relying on reflective surface alone.
Our Owens Corning Insulation Removal & Replacement Process
- 1
Call and scheduling. A live person answers (830) 549-6646 24/7. We book a site visit, and you get a text when Wes Okafor or your assigned technician is en route.
- 2
Attic inspection and blower-door test. We run a pressurization diagnostic - a blower-door test that reads how much conditioned air your home loses per hour at 50 pascals of pressure. In Seguin’s older neighborhoods, we typically see 3,500-5,500 CFM50 before any work begins. We photograph existing Owens Corning product labels, depth measurements, and problem areas.
- 3
Written price and scope. You get a flat price, written scope, and written warranty before anyone lifts a tool. Haven Standard Clause 1: no work starts without it. We note whether we’ll use fresh Owens Corning material or cross-reference with Johns Manville, Knauf, or Rockwool depending on availability and your preference.
- 4
Air sealing first, then removal. Every penetration, top plate gap, and can-light housing gets sealed with fire-rated caulk or foam. Only then do we vacuum out old insulation with HEPA-contained extraction. The report goes home with you - the numbers do the talking.
- 5
Replacement and verification. New insulation goes in to specified depth with even distribution. We run the blower-door test again and hand you a printed pre- and post-installation report with actual ACH50 numbers.
- 6
Documented Photo Record and cleanup. Full photo set, final walkthrough, and 365-Day Done Right Promise documentation. The crew leaves with the old material hauled away.

FAQs
No - Owens Corning’s product warranties cover manufacturing defects in material still installed, not removal of existing product. As an independent Owens Corning service provider, we document original product labels and installation dates for your records, but we do not represent Owens Corning. Any remaining warranty on newly installed Owens Corning product is between you and the manufacturer; we provide the installation documentation they require if a claim arises. Call (830) 549-6646 and we’ll explain what paperwork to keep.
Most residential attic jobs are completed in one day, with larger or vermiculite-contaminated attics requiring two days. We schedule arrival between 8 and 9 a.m. in Seguin proper and nearby areas, and you’ll get a text when the crew is on the way. Same-week scheduling is usually available. Call (830) 549-6646 to check current openings - estimates are free.
Sometimes, but it’s rarely the right choice. Compressed or moisture-affected Fiberglas loses its labeled R-value and creates an uneven base that invites thermal bridging. In Seguin’s climate, we find that layering over old material without addressing air leaks first typically wastes 20-30% of the new insulation’s performance. We price both approaches and show you the blower-door difference so you can decide with numbers, not guesses. Call for a free estimate.
We can source current Owens Corning PINK Fiberglas and EcoTouch lines through our supplier network, but exact matches to discontinued products aren’t always possible or advisable. Older L77 loosefill, for instance, has been superseded by newer formulations with better settling resistance. We specify the closest modern equivalent in our written scope, note the R-value improvement, and can cross-reference with Johns Manville, Knauf, or Rockwool if you prefer. Call (830) 549-6646 to review options.
Stop disturbing it and call us. We do not test in-house - we coordinate with Texas-licensed abatement contractors for sampling and removal under EPA and TDSHS protocols. The third-party cost is separate from our replacement work, and we won’t start insulation installation until clearance documentation is in hand. We’ve managed this process for Seguin homeowners near the hospital district and in 1970s subdivisions where vermiculite was common. Call (830) 549-6646 for guidance - the initial site visit is free.
