CertainTeed Insulation Removal & Replacement in West Hollywood: What to Know First
We provide independent CertainTeed insulation removal and replacement in West Hollywood, with most jobs completed in a single day and a written price delivered before any work starts. Typical attic insulation removal and replacement runs $2,800-$5,400 for homes in this market, depending on square footage, contamination level, and whether the existing product is a CertainTeed line that requires specialized handling. This page is for homeowners who’ve found CertainTeed insulation in their attic - whether it’s degraded CertaSpray foam, settled Optima blown-in, or older CertainTeed fiberglass batts showing compression failure - and need it removed safely and replaced with a product that performs. Call (213) 306-2607 for a free estimate with a written scope.
How CertainTeed Products Fail - and How We Fix Them
- CertaSpray open-cell foam shrinkage in West Hollywood’s dry climate. We’ve pulled back CertaSpray FG (the open-cell line) in multiple homes north of Melrose where the material pulled away from rafter bays, creating thermal bypass channels. The foam shrinks as it ages in low-humidity conditions, which is most of the year here. Our fix: complete removal with cold-knife cutting, HEPA containment, and replacement with a closed-cell product or dense-pack cellulose that doesn’t shrink under these conditions.
- Optima blown-in fiberglass settling below labeled R-value. Optima is marketed for coverage at specific depths, but in West Hollywood’s 1920s-1950s bungalows with irregular joist spacing, we’ve measured settled depths 30-40% below spec after 7-10 years. The product doesn’t fail chemically; it fails geometrically. We remove the settled material, air-seal the attic floor properly, then reinstall to true depth with a product that holds its loft.
- CertainTeed fiberglass batts compressed by storage or foot traffic. Older CertainTeed unfaced batts in attics off Santa Monica Boulevard are often compressed into 50% of their original thickness by decades of homeowner storage. Compressed fiberglass loses R-value proportionally. We remove the compressed material, which often contains rodent contamination, and replace with blown-in product that fills irregular cavities and can’t be walked on.
- CertaSpray FG off-gassing in conditioned attics. In homes where CertaSpray was applied directly to roof decking in a conditioned attic assembly, we’ve had owners report persistent odor. The issue is incomplete curing during original installation, common in fast-production builds from 2012-2018. Removal requires full mechanical stripping and replacement; partial removal leaves the problem. We document the scope with photos before touching anything.
- CertainTeed mineral wool (Thermafiber) moisture retention near roof leaks. Thermafiber industrial mineral wool doesn’t mold easily, but it holds water like a sponge when roof leaks occur - which they do in West Hollywood during our brief but intense winter rains. Saturated mineral wool is heavy enough to distort drywall ceilings. We remove the waterlogged sections, trace the leak path, and replace with a product appropriate for the repaired assembly.
Our CertainTeed Insulation Removal & Replacement Process
- 1
Call and schedule. A live person answers (213) 306-2607. We book a site visit, usually within 48 hours for West Hollywood addresses.
- 2
Attic inspection and blower-door test. We pressurize the house to 50 pascals - a blower-door test that shows, in one number, how much air the building envelope is losing. We identify the CertainTeed product line, its condition, and any air-leak paths that must be sealed before new insulation goes in.
- 3
Written price and scope. Under Haven Standard Clause 1: flat price, written scope, written warranty before anyone lifts a tool. No exceptions. If you have a competing quote, we provide a Free Second Opinion and read it with you.
- 4
Removal and containment. HEPA-filtered negative-air setup for all removal work. CertainTeed foam products require cold-knife cutting to avoid aerosolizing isocyanates. Fiberglass and mineral wool are bagged on-site. We photograph everything.
- 5
Air sealing, then insulation. Seal the leaks first. Then insulate. The R-value on the bag assumes you did it in that order. We seal top plates, can lights, plumbing and electrical penetrations, then install the replacement product to spec.
- 6
Post-job documentation. Blower-door test repeated to verify air-sealing improvement. Documented Photo Record delivered. Written warranty and 365-Day Done Right Promise in hand before we leave.

Why West Hollywood Homeowners Call Topside Attic Insulation West Hollywood for CertainTeed Work
We’ve been inside attics across the LA basin since 2016, and the bungalows off Santa Monica Boulevard are some of the most challenging - tight access, mixed original and retrofit insulation, and owners who read their estimates carefully before signing. Wes Okafor built this company on blower-door testing and written documentation, not on how long we’ve been around. Every CertainTeed removal job gets the same protocol: HEPA containment, cold-knife foam cutting where needed, air sealing before insulation, and a post-job blower-door number you can compare to your pre-job reading. The 365-Day Done Right Promise applies to all work. Materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and others - no proprietary lock-in, so we specify what fits your assembly, not what moves our inventory. Calls are answered by a live person, 24/7.
FAQs
CertainTeed’s product warranty covers manufacturing defects, not installation or removal performed by others. As an independent CertainTeed service provider, we document the original product condition with photos before removal so any valid manufacturing claim can still be pursued. Our work carries its own 365-Day Done Right Promise. Call (213) 306-2607 if you have warranty paperwork you’d like us to review with you.
We can source current CertainTeed products if matching is important for warranty continuity, but we don’t recommend it automatically. The product that failed may not be the right product for your assembly. We specify based on blower-door results, climate, and roof-deck or floor application - not brand loyalty. Our materials come from Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, and others.
If the product is compressed, contaminated, or a foam that’s pulling away from framing, removal is necessary - topping off hides the problem. If it’s clean fiberglass that’s simply settled and the attic floor is already air-sealed, topping may work. We determine this during inspection, not over the phone. Call (213) 306-2607 for a free assessment.
Most West Hollywood inspections happen within 48 hours of calling (213) 306-2607. Scheduling the work itself depends on containment setup requirements - standard fiberglass removal often starts within a week; spray foam removal with full HEPA protocol may need 10-14 days to crew properly. We don’t rush the setup.
Yes. CertaSpray FG and similar open-cell foams require mechanical cutting, negative-air containment, and longer crew time. The material doesn’t bag neatly; it comes out in chunks that need controlled disposal. Expect 40-60% higher removal cost versus fiberglass, before replacement product is figured. We put the full number in writing before starting.
