This page is for West Covina homeowners whose CertainTeed insulation has failed, gotten wet, been torn up by rodents, or simply stopped doing its job after decades of service. Walt Brenner and our crew have been pulling old insulation out of attics across West Covina since 2000, and we’ve seen every failure mode CertainTeed products can throw at a house. We’ll tell you straight what’s worth fixing, what’s worth replacing, and what it costs before we ever set foot in your attic.

How CertainTeed Products Fail - and How We Fix Them

• CertainTeed InsulSafe blown-in fiberglass settles and loses R-value. We see this constantly in West Covina homes built in the 1980s and 1990s, especially near the Eastland Center corridor where original construction rarely got more than R-19 up top. InsulSafe compresses over time under its own weight and from foot traffic during HVAC or electrical work. A 10-inch layer that started at R-30 can be sitting at R-19 and the homeowner never knows it. We remove the settled material, air-seal the attic floor, and blow fresh insulation to the depth West Covina’s climate actually needs.
• DryRight or Touch’n’Foil vapor barriers trap moisture after roof leaks. CertainTeed batt products with built-in vapor retarders work fine until a roof leak or bathroom vent issue puts water where it doesn’t belong. Once that kraft or foil facing gets saturated against the drywall, you get mold growth and degraded R-value that no amount of drying fully reverses. We pull the wet batts, check the roof deck for ongoing leaks, and replace with either new faced batts or blown-in depending on the attic configuration.
• Rodents turn CertainTeed batt insulation into nesting material. This is the number one reason West Covina homeowners call us for removal. Rats and mice love tearing apart fiberglass batts, and CertainTeed’s soft, fluffy texture makes it easy for them to shred and tunnel through. Once rodent activity starts, the insulation is contaminated with droppings and urine and has to come out. We remove it, sanitize the attic, seal entry points, and replace with fresh material. This job takes longer than a standard replacement, usually two full days.
• CertainTeed fiberglass batts installed wrong from the start. We find plenty of homes where the original installer compressed the batts around wiring, stuffed them into joist bays too tightly, or left gaps at the eaves. CertainTeed products perform exactly to spec when installed correctly, but a sloppy install cuts their effective R-value by 30 to 40 percent. We remove the poorly installed material and redo the job properly, which often means switching to blown-in for better coverage in tight West Covina attic spaces.
• Old CertainTeed loose-fill from the 1970s that predates modern safety standards. Some West Covina houses still have rock wool or early fiberglass loose-fill insulation from the CertainTeed product lines of that era. It’s dusty, degraded, and often too shallow to do anything useful. Removal here is about getting the attic clean and safe before we install new material. We run the vacuum system, bag everything, and dispose of it properly.

Our CertainTeed Insulation Removal & Replacement Process

1. 1
   You call (626) 612-1532 and describe what’s going on. A live person answers, not a voicemail. We ask about the attic size, when the house was built, and what’s making you think the insulation needs attention. If it sounds straightforward, we schedule a visit and there’s no trip charge inside our service county.
2. 2
   We inspect the attic and take readings. Walt or one of our background-checked techs measures the current insulation depth, checks for moisture, looks for rodent signs, and documents what’s actually up there. You get a straight answer: replace it, remove and replace it, or leave it alone if it’s still doing its job.
3. 3
   We give you a written, upfront price. No vague estimates, no surprises after we start. The quote tells you exactly what we’re removing, what we’re installing, and what it costs. If you have a written estimate from another company, bring it and we’ll give you a free second opinion.
4. 4
   Removal day. Our crew lays down protection, runs commercial vacuum equipment to pull out the old material, bags it, and cleans the attic thoroughly. For contaminated insulation, we sanitize before anything new goes in. The whole process is methodical and we don’t leave a mess in your house.
5. 5
   We install the replacement insulation. Whether it’s fresh CertainTeed batts, blown-in fiberglass, or another brand that fits your attic better, we install it to the correct depth and density for West Covina’s climate. We also air-seal the attic floor while we’re up there because insulation without air sealing is half a job.
6. 6
   We walk you through the work and stand behind it. You see the before and after, we explain the R-value you’re getting now, and every job is covered by our lifetime Done Right Promise. If it’s not done right, we come back and make it right. No runaround.

What CertainTeed Insulation Removal & Replacement Costs in West Covina

Here’s what we charge for common CertainTeed removal and replacement scenarios in West Covina. These are real ranges based on the jobs we’ve done in this city over the last several years.

• Standard attic removal and blown-in replacement: $1,800-$3,200 for a typical West Covina ranch or two-story, assuming 1,200-1,800 square feet of attic and no contamination.
• Contaminated insulation removal, sanitizing, and replacement: $2,800-$5,500 depending on the severity of rodent activity, how much material has to come out, and whether entry-point sealing is included.
• Batt removal and re-batt with CertainTeed or equivalent: $2,200-$4,000 for homes where the original batts were faced and the homeowner wants faced batts back in.
• Partial removal and top-up: $800-$1,600 when the existing insulation is still acceptable in most areas and we only remove the bad sections before blowing new material over the whole attic.

What moves the price: attic accessibility, contamination, the height of the roof deck, and whether we’re sealing rodent entry points alongside the insulation work. Every quote includes cleanup and disposal. Call (626) 612-1532 for exact pricing on your West Covina home. Estimates are free, and we’ll give you the number before any work starts.
