Owens Corning Insulation Removal & Replacement in Morgan Hill: What to Know First
As an independent Owens Corning service provider in Morgan Hill, we remove and replace failed or contaminated Owens Corning insulation systems, typically completing attic jobs in one day with a written price locked before any work starts. Most Morgan Hill homeowners with Owens Corning batts or blown-in systems see removal and replacement costs between $2,800 and $6,400 depending on attic square footage, contamination level, and whether air sealing is required beneath the old material. We do not begin insulation removal until the homeowner has a written scope, a written warranty, and a flat price under Haven Standard Clause 1. Call (669) 280-8103 to schedule a free estimate with documented photo record included.
This page is for Morgan Hill homeowners who’ve found Owens Corning insulation in their attic, walls, or crawl space and need to know whether removal is necessary, what replacement options exist, and what the work actually costs in Santa Clara County’s climate.
How Owens Corning Products Fail - and How We Fix Them
- Owens Corning EcoTouch PINK Fiberglas Batts - compression and moisture wicking in Morgan Hill’s winter fog cycles. These batts lose their labeled R-value when compressed into irregular joist bays or when roof leaks from our occasional heavy January storms saturate the facing. We remove the compressed or stained batts entirely, seal all top plates and penetration points with acrylic latex or fire-rated foam, then replace with new unfaced batts or blown-in fiberglass at full loft thickness.
- Owens Corning AttiCat Blown-In Insulation - settling below original depth and thermal drift. The AttiCat system installs loose-fill fiberglass that can settle 10-15% in the first two years, especially in homes near Morgan Hill’s eastern hills where temperature swings between 90°F summer days and 35°F winter nights accelerate fiber migration. We vacuum out settled material, measure actual remaining depth against the original bag count, and reinstall to full specified depth with fresh AttiCat or an alternative blown-in product.
- Owens Corning FOAMULAR XPS Rigid Board in crawl spaces - rodent tunneling and condensation at the rim joist. Rigid foam boards in Morgan Hill’s older homes near downtown often show gnaw marks from roof rat activity or dew-point condensation where the board meets unsealed sill plates. We remove contaminated boards, treat the rim joist with closed-cell spray foam for air sealing and moisture control, and replace with new FOAMULAR only if the homeowner prefers rigid board over spray foam.
- Owens Corning ProPink High-Performance Conditioned Attic Systems - failed adhesive on foam-applied applications. In the newer Morgan Hill builds off East Main where ProPink L77 loose-fill was applied over spray foam in conditioned attic designs, we’ve found delamination where the foam substrate wasn’t properly cleaned. We remove the separated loose-fill, assess the foam substrate for adhesion failure, and reapply only after mechanical cleaning and primer treatment.
- Owens Corning Thermafiber Mineral Wool - water staining from HVAC condensate lines. Mineral wool resists fire and moisture better than fiberglass, but it’s not waterproof. In Morgan Hill homes with attic-mounted air handlers, we’ve pulled saturated Thermafiber batts beneath condensate pans that overflowed during Santa Clara County’s occasional freeze events. We remove the wet material, relocate or re-pan the condensate line, seal the platform, and replace with fresh mineral wool or an alternative suited to the location.
Our Owens Corning Insulation Removal & Replacement Process

- 1
Call and scheduling. A live person answers, or you text. We book a site visit in Morgan Hill, usually within 48 hours. You receive a named technician and a text when they’re en route - Haven Standard: Arrive on schedule.
- 2
Attic inspection and contamination assessment. We photograph everything. We test for asbestos if the home was built before 1990, particularly important in the older Morgan Hill neighborhoods near Oakwood Avenue where vermiculite was common.
- 3
Blower-door test (applicable jobs). We run a pressurization reading that shows, in one number, how much air your building envelope is losing. This becomes our baseline. Seal the leaks first. The insulation just holds what you’ve already captured.
- 4
Written price, scope, and warranty delivered. No work starts without it. Flat price, written scope, written warranty - Haven Standard Clause 1. Free Second Opinion available on any competing written estimate.
- 5
Removal and air sealing. We vacuum out old Owens Corning material with HEPA-contained equipment, then seal every top plate, can light boot, wire penetration, and attic hatch perimeter before any new insulation goes in.
- 6
Replacement, documentation, and final blower-door test. New insulation installed to specified depth or R-value. We deliver your Documented Photo Record and, on applicable jobs, before-and-after blower-door numbers so you can verify the air-sealing result. The 365-Day Done Right Promise applies from day one.
What Owens Corning Insulation Removal & Replacement Costs in Morgan Hill
Most attic insulation removal and replacement jobs in Morgan Hill homes between 1,200 and 2,400 square feet run $2,800 to $6,400. Here’s how the numbers break for typical Owens Corning scenarios:
| Scenario | Price Range |
|---|---|
| Clean removal of EcoTouch batts, air sealing, replacement with new batts | $2,800 - $4,200 |
| AttiCat blown-in removal and replacement to full depth (R-38 to R-49) | $3,400 - $5,200 |
| Contaminated insulation removal (rodent, moisture, mold) with sanitization | $4,200 - $6,400 |
| Vermiculite removal with asbestos abatement coordination | $5,800 - $9,500+ |
| Conditioned attic ProPink L77 removal and reapplication over foam | $4,600 - $7,200 |
What moves the price: attic square footage, accessibility (truss spacing, ductwork density), contamination level requiring HEPA containment, and whether the original installation included air sealing that we must repair or complete from scratch. Homes in the hillier Morgan Hill areas toward Uvas Canyon often have complex rooflines that add labor time.

Why Morgan Hill Homeowners Call Topside Attic Insulation Morgan Hill for Owens Corning Work

We’ve logged jobs in Morgan Hill neighborhoods from the houses near Oakwood Avenue all the way up toward the newer builds off East Main, and we’ve seen how Owens Corning products perform in Santa Clara County’s specific climate - the summer heat gain through poorly sealed attic floors, the winter fog-driven moisture that finds its way into compressed batts.
Wes Okafor, our owner and lead technician, learned the trade at Olive-Harvey College in Chicago, where blower-door equipment came before any bag of blown-in cellulose. That sequencing still governs our work: seal first, insulate second. We publish before-and-after blower-door numbers on every applicable job so you can see the performance change you paid for, not just take our word for it.
We’re independent - not affiliated with or authorized by Owens Corning - which means we source replacement materials from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and others with no proprietary lock-in. If Reflectix radiant barrier makes more sense for your Morgan Hill roof assembly than another layer of fiberglass, we’ll tell you straight and price both.
The 365-Day Done Right Promise covers all completed work. Calls are answered by a live person 24/7. Background-checked, uniformed technicians. Written price before any work starts, always.
FAQs
Owens Corning’s product warranties cover defects in manufacturing, not installation or removal by third parties. As an independent service provider, our removal work does not affect any remaining product warranty on the original material, though warranty claims on removed product are moot once it’s out of your home. If you’re concerned about warranty status on newer Owens Corning systems, we photograph batch numbers and installation dates during removal for your records. Call (669) 280-8103 and we’ll review what documentation we can preserve.
We can source current Owens Corning products including EcoTouch, AttiCat, ProPink, and Thermafiber lines, but exact batch matching on aged insulation is impossible - fiberglass yellows, binders degrade, and product lines update. We specify replacement by R-value and application type rather than visual match, which is what actually determines thermal performance. If your original installation used a discontinued Owens Corning line, we’ll cross-reference the labeled R-value and install the current equivalent or an alternative from our multi-brand inventory. Call for a free estimate and we’ll show you the options side by side.
Adding over old insulation is cheaper upfront but often costs more over the life of the home. In Morgan Hill’s climate, we’ve found that layering new Owens Corning blown-in over compressed or moisture-stained existing material traps humidity, masks air leaks that should be sealed, and prevents proper depth measurement. Removal costs $1.20 to $2.10 per square foot additional in most attics, but it allows full air sealing, accurate R-value installation, and eliminates odor or contamination carryover. For homes with rodent activity or roof leaks, removal is the only defensible approach. Call (669) 280-8103 for a written price on both approaches.
Most clean attic jobs finish in one working day; contaminated removals requiring HEPA containment or asbestos coordination take two to three days. We schedule Morgan Hill site visits within 48 hours of contact, and written estimates are delivered same-day or next-day. We do not offer same-day start - the Haven Standard requires written price, scope, and warranty delivery before any work begins - but we can often begin within 72 hours of estimate approval. Call (669) 280-8103 to check current availability.
We source current Owens Corning products directly when they’re the right choice for the application, but we’re not locked to any single brand. For some Morgan Hill homes, Johns Manville blown-in at equivalent R-value costs less per square foot with identical thermal performance; for others, Rockwool or Knauf better suits the fire-rating or moisture conditions. We specify by performance spec, not brand loyalty, and we show you the material options and price differences in writing before you decide. Call for a free estimate with multi-brand pricing.
