CertainTeed Insulation Removal & Replacement in Pasadena: What to Know First
We provide independent CertainTeed insulation removal and replacement in Pasadena, typically completing attic jobs in one to two days with a written price delivered before any work starts. Most CertainTeed insulation removal and replacement jobs in Pasadena homes run between $2,800 and $6,500 depending on attic size, contamination level, and whether air sealing is needed beneath the existing layer. We are not affiliated with or authorized by CertainTeed; we are an independent service provider who sources CertainTeed materials alongside Owens Corning, Johns Manville, Knauf, and others so you are never locked into a single product line.
This page is for Pasadena homeowners who have found CertainTeed insulation in their attic, suspect it is underperforming, contaminated, or improperly installed, and want a contractor who will document the condition, explain the fix in plain numbers, and put the price in writing before lifting a tool. Call (213) 816-5351 for a free estimate or a free second opinion on any written quote you already have.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed InsulSafe SP settled below labeled depth in Pasadena’s dry heat. The blown-in fiberglass was installed at a nominal R-38 depth in a 1980s ranch near Hastings Ranch, but thermal imaging showed a 40-degree attic floor delta on a July afternoon. We removed the compacted material, sealed top plates and can-light penetrations, then re-installed to true R-38 with depth markers photographed every 50 square feet. The blower-door reading dropped from 3,800 CFM50 to 2,100.
- CertainTeed SpeedyR loose-fill cellulose absorbed roof-leak moisture in Bungalow Heaven. Cellulose wicks water laterally; by the time staining shows on the ceiling below, the insulation has already compressed and lost R-value. We vacuum-extracted the contaminated material, treated the deck for mold, installed baffles for ventilation, and replaced with Rockwool R-30 - a non-wicking alternative we often recommend in Pasadena’s older homes with original clay-tile roofs.
- CertainTeed Optima open-blow in kneewalls fell away from studs in a 1923 Craftsman on Orange Grove Boulevard. Without an air barrier, loose-fill in vertical assemblies slides to the base over time. We removed the collapsed material, installed netting to contain new dense-pack cellulose, and sealed the kneewall top and bottom plates. The homeowner’s second-floor bedroom now holds temperature within 2 degrees of the thermostat setpoint.
- CertainTeed CertaSpray open-cell foam degraded where roof sheathing temperatures exceeded 180°F on south-facing Pasadena slopes. Open-cell foam is vapor-permeable; in our climate, that means summer moisture drives into the foam and can degrade the adhesion to decking. We cut away the failed sections, installed proper venting with site-built baffles, and replaced with closed-cell Demilec Heatlok HFO in the critical zones and Rockwool batts in the remainder.
- CertainTeed fiberglass batts installed pre-2005 were sized for 2×4 walls, not the 2×6 retrofits common in Pasadena’s energy-upgrade program work. A half-inch gap on either side of a batt cuts effective R-value by 20 percent. We remove the undersized material, foam-seal the stud bays, and install full-cavity batts or dense-pack to eliminate convection loops.
Our CertainTeed Insulation Removal & Replacement Process

- 1
Site visit and written scope. We inspect the attic, photograph the existing CertainTeed product and any damage, and deliver a written price with line-item breakdown before any work starts. Haven Standard Clause 1: no exceptions.
- 2
Contamination and moisture assessment. We test for asbestos if the home was built before 1990, check for rodent activity, and use a moisture meter on decking and existing insulation. In Pasadena’s variable microclimates, a north-facing roof below 1,400 feet elevation can hold moisture that a south-facing slope at 2,000 feet never sees.
- 3
Air sealing before removal. We seal accessible leaks at top plates, plumbing and electrical penetrations, and chase openings while the old insulation is still in place - it shows us where the air is moving. Then we extract.
- 4
Removal and documentation. We use HEPA-filtered vacuum extraction for loose-fill, bagged removal for batts, and controlled cutting for degraded foam. Every stage is photographed; you receive the Documented Photo Record with the final invoice.
- 5
Replacement and verification. We install the specified replacement material, verify depth and coverage, and run a blower-door test - a pressurization reading that shows, in one number, how much air your building envelope is losing. Before-and-after numbers are published on every applicable job.
- 6
Written warranty and 365-Day Done Right Promise. You receive a written scope, the photo record, blower-door results if applicable, and our warranty before we leave. If it’s not done right, we make it right.

Why Pasadena Homeowners Call Topside Attic Insulation Pasadena for CertainTeed Work

We have been in attics from Bungalow Heaven to the older Craftsmans along Pasadena’s Orange Grove corridor since 2016, and we have pulled back enough CertainTeed products to know which failure patterns repeat in this climate. Wes Okafor and our crew do not sell insulation by the bag; we sell measured performance, documented in blower-door readings and thermal images you can hold in your hand.
Our materials come from CertainTeed, Owens Corning, Johns Manville, Knauf, Rockwool, and others - no proprietary lock-in means we specify what performs, not what a manufacturer needs to move. Every job gets a written price first, a Documented Photo Record at completion, and the 365-Day Done Right Promise. Calls are answered by a live person, 24/7. Seal the leaks first. Then insulate. The numbers will tell you why.
FAQs
No. Product warranties cover defects in the material itself, not the installation or removal. CertainTeed’s limited warranty on insulation products applies to manufacturing defects; it does not restrict who removes or replaces the material. If your original installer offered a separate workmanship guarantee, that may have its own terms, but the product warranty remains intact. Call (213) 816-5351 and we will review any paperwork you have.
We source CertainTeed materials through standard distribution channels when they are the right specification for the job. We also use equivalent or superior products from Owens Corning, Knauf, and Rockwool if they better match your home’s needs or budget. We do not claim exclusive or preferred status with any brand. You see the product labels before installation.
Repair is rarely practical for blown-in or batt products. Once fiberglass compresses or cellulose wicks moisture, the R-value is permanently degraded; adding new material on top creates thermal irregularities and can mask air leaks. Removal and replacement is the correct fix in nearly every case we see in Pasadena. We will show you the thermal images and explain why.
Most attic jobs are completed in one to two days. Contaminated or vermiculite jobs may take three to five days due to testing and abatement protocols. We schedule within a week of your approved written price for standard jobs, and we offer emergency scheduling for health hazards like active rodent infestation. Call (213) 816-5351 for availability.
You receive a written scope of work, the final invoice matching your pre-approved price, a Documented Photo Record of before, during, and after conditions, and on applicable jobs, before-and-after blower-door readings. Under Haven Standard, you have this in hand before we leave. If anything is missing, we return to complete the record.
