CertainTeed Insulation Removal & Replacement in Chicago: What to Know First
We provide independent CertainTeed insulation removal and replacement across Chicago, with most attic jobs completed in one to two days once we’re on site. For a standard Chicago bungalow or two-flat attic, removal and replacement typically runs between $2,800 and $6,500 depending on square footage, access, and what we find under the old material. We’re not a CertainTeed authorized contractor; we’re an independent CertainTeed service provider, which means we recommend what the house actually needs, not what a brand program tells us to sell.
This page is for Chicago homeowners who bought CertainTeed insulation, have watched it underperform or fail, and want it out and replaced with something that works in this climate. If that’s you, call (218) 261-7714 and we’ll schedule a written assessment before any work starts.
How CertainTeed Products Fail - and How We Fix Them
- CertainTeed InsulSafe SP Fiberglass blown-in settles in Chicago attics faster than the bag advertises. We regularly pull InsulSafe SP out of attics in Jefferson Park and Portage Park where the material has compacted from R-38 to something closer to R-24 in under eight years. The cause is usually attic humidity cycling from our winters, which compresses the loose-fill structure. Our fix: full removal with a commercial vacuum, then replacement with blown-in fiberglass or cellulose at a verified depth, not an eyeballed one.
- CertainTeed fiberglass batts installed in rim joists wick moisture and crumble over time. In a rim joist, fiberglass has no air barrier behind it, so Chicago’s winter air blows straight through and condenses inside the batt. By year six or seven, the batt is a damp wad that reads like an open window on a blower-door test. We remove the batt, air-seal the rim joist cavity with spray foam or rigid board and canned foam at the edges, then re-insulate. This is the insulation equivalent of leaving a window open all January, and we see it in roughly one out of every four pre-2010 homes we test.
- Mice and squirrels treat CertainTeed batt insulation as bedding material in Chicago attics. CertainTeed’s white and pink fiberglass batts don’t deter rodents, and once a squirrel winters in your attic, the insulation is contaminated with droppings, urine, and shredded nesting material. We remove it all, sanitize the attic floor, seal the entry points, and then replace with fresh material. We don’t blow new insulation over contaminated batts; it just hides the problem and makes the next removal more expensive.
- Vermiculite insulation in pre-1990 Chicago homes often traces back to the Libby, Montana mine, and CertainTeed never made vermiculite, but it’s commonly found mixed into older attics alongside brand-label batts. If we find vermiculite during a CertainTeed removal, we stop and follow Illinois and EPA protocol for testing and abatement. This is a real scenario in Chicago’s older neighborhoods like Rogers Park and Avondale, where attics have been topped up multiple times over decades.
- CertainTeed DryRight and MemBrain smart vapor retarders fail when installed on the wrong side of the assembly in Chicago’s climate zone 5. We’ve pulled these products out of walls in homes where a previous contractor installed them backwards, trapping moisture inside wall cavities. The fix is removal, inspection of the sheathing for rot, and reinstallation per manufacturer’s climate-zone specification.
On most CertainTeed jobs we can source OEM material if the job calls for it, but more often than not, we recommend a material matched to the assembly, not a label on the bag. We work with Owens Corning, Johns Manville, Knauf, Rockwool, GreenFiber, and Icynene, and occasionally Reflectix for specific radiant-barrier applications. No proprietary lock-in. If your house needs Johns Manville and you currently have CertainTeed, we’ll tell you that and give you the written price for both paths.
Our CertainTeed Insulation Removal & Replacement Process
- 1
Written assessment and blower-door test. Before we touch a single batt, we run a blower-door test, a calibrated pressure diagnostic that tells us how much outside air is leaking into the house. The number goes on the written scope. That’s Haven Standard Clause 1: a written price before any work starts.
- 2
Removal with a commercial-grade vacuum. We bring truck-mounted vacuums with HEPA filtration, not a shop vac and a prayer. All material leaves through sealed hoses to a trailer outside, and the attic floor is swept clean with the hand tools the crew carries for exactly this work.
- 3
Inspection of what’s underneath. Once the old CertainTeed material is out, we inspect the attic floor, top plates, can lights, plumbing penetrations, and chase ways. This is where we find air leaks that no amount of new insulation would fix.
- 4
Air sealing before any new material goes in. We seal top plates, penetrations, can-light housings from below where possible, and any other gaps we’ve documented. Sealed first, then insulated, in that order. We will never blow insulation over an unsealed attic floor.
- 5
Replacement at verified depth and density. We install new insulation to the R-value the scope specifies, using depth markers and density checks as we go. Photos are taken throughout. The blower-door test gets run again after the work is done.
- 6
Documented close-out. You get the printed report: pre-installation ACH50 reading, post-installation ACH50 reading, installed R-values by zone, and a photo log of air-sealing locations. Every applicable job gets before-and-after blower-door numbers published so you can see the performance change you paid for.
What CertainTeed Insulation Removal & Replacement Costs in Chicago
Most CertainTeed removal and replacement jobs in Chicago fall into these ranges:
- Attic removal and blown-in replacement, 800-1,200 sq ft: $2,800-$4,800
- Full attic removal, air sealing, and replacement, 1,200-1,800 sq ft: $4,200-$6,500
- Rim joist removal, air sealing, and re-insulation (per 20-linear-foot section): $900-$1,600
- Contaminated insulation removal with sanitization, per attic: add $800-$1,500 to base removal
- Vermiculite testing and abatement, when found: quoted separately with a licensed abatement partner
The price moves based on square footage, attic access (Chicago bungalow kneewalls are slower work than a full-size attic with standing room), contamination level, and whether air sealing is needed first. Every job gets a flat written price before we start. No time-and-materials guessing. Call (218) 261-7714 and we’ll come out, run the numbers, and put the price in writing.
Why Chicago Homeowners Call Topside Attic Insulation for CertainTeed Work
We run the blower-door test before any material goes in, which means you know exactly why you’re removing the old insulation before you spend a dollar replacing it. We’ve sealed and insulated more than 9,000 homes since 2016, every one with a written price before work started and a documented record when the crew left. Our 365-Day Done Right Promise covers all completed work: if it’s not done right, we make it right. We answer the phone 24/7 with a live person, and you’ll get a named technician and a text when they’re on the way. Wes Okafor grew up on the Northwest Side about six blocks from the Portage Park field house, and he’s been doing insulation work in Chicago for over twenty years. He knows which CertainTeed products hold up in this climate and which ones don’t, because he’s pulled them all out of attics from Beverly to Edgewater. Seal the holes first. Then add the R-value. The numbers will tell you whether it worked.
FAQs
No. Removing insulation that has failed or been contaminated does not void a warranty that only covers manufacturing defects in the material itself. Once the material is installed, performance depends on the installation and the house environment, both of which are outside the manufacturer’s control. If you’re unsure whether your CertainTeed insulation is still under warranty, we can review the paperwork with you before removal.
Most attic jobs are completed in one to two days once we start. Contamination remediation or vermiculite abatement adds time, typically a few days to a week depending on testing and abatement scheduling. Call (218) 261-7714 and we’ll give you a written scope with a completion date before any work begins.
Adding new insulation on top of failed, contaminated, or compacted CertainTeed material is almost always a mistake in the long run. The old material continues to harbor whatever problem it has, and you pay twice: once to bury it and once to eventually remove the combined mess. Removal and replacement costs more upfront, but it’s the only approach that actually fixes the thermal and air-sealing problems we find in Chicago homes.
Yes, and we’ll usually exceed it. We install to the R-value the house needs for Chicago’s climate zone 5, which for most attics is R-49 to R-60. If your old CertainTeed batts were R-30 and you’ve been freezing every winter, that’s why. We’ll quote the trade-up and show you the difference in the blower-door numbers after installation.
We stop and put it in writing. Whether it’s vermiculite, mold, rodent damage, or rotted sheathing, we document it, explain what it means, and give you a written price for remediation before we proceed. You’re never on the hook for surprise work you didn’t approve. Call (218) 261-7714 for a free written estimate, and we’ll walk you through exactly what the crew will do before anyone lifts a tool.
