Trusted Insulation Removal & Replacement for Chicago Homeowners
Insulation Removal & Replacement - Chicago typically costs between $1,800 and $4,200 for a standard attic, with most jobs completed in one to two days. The work involves extracting old, compacted, or contaminated material, air sealing the exposed cavity, and blowing or batting in new insulation rated for our climate zone. Topside Attic Insulation has removed and replaced insulation in over 9,000 Chicago-area homes since 2016, and our crews are available for same-week scheduling across the city and inner suburbs. Call (218) 261-7714 for a written price before any work begins.
What separates us from every other insulation contractor in Chicago is the order of operations. We do not blow new insulation over an unsealed attic floor, ever. The air sealing happens first, then the insulation goes in. That sequence is the difference between a house that holds heat in January and one that just has thicker fluff over the same leaks. Our home performance work is built on this principle, and it’s why we publish before-and-after blower-door numbers on every applicable job.
Wes Okafor founded Topside Attic Insulation to fix what he kept seeing in Chicago attics: new insulation laid directly over mouse droppings, dead can lights leaking warm air into the roof deck, and homeowners who paid twice for the same problem. That ends with the written scope in your hand before any tool leaves the truck.
What Our Insulation Removal & Replacement Service Includes
Attic Insulation Removal
Attic insulation removal is the extraction of existing material from the attic floor, typically fiberglass batts or blown-in cellulose, using a commercial vacuum system that runs to a sealed bag outside the home. This is necessary when the material has compacted below useful R-value, been saturated by roof leaks, or become packed down to the point where it no longer insulates. We remove the full depth, expose the attic floor, and give you a clean cavity ready for air sealing and new insulation. Every removal includes a Documented Photo Record showing the attic before, during, and after the job.
Contaminated Insulation Removal
Contaminated insulation is any material that has absorbed rodent urine, feces, nesting debris, or water, and it stops performing while actively degrading your indoor air quality. In Chicago and nearby Hammond, squirrels and roof rats are the most common culprits, and their presence usually shows up as brown staining, a sharp ammonia smell, or trails through the insulation. We remove the contaminated material entirely, not just the visible spots, then sanitize the affected area before any new insulation is installed. The blower-door reading we take after this work often shows a dramatic air leakage reduction, since rodent entry points are sealed as part of the job.
Vermiculite & Old Insulation Removal
Vermiculite is a pebble-like loose-fill insulation installed in many Chicago homes built before 1990, and some of it contains asbestos fibers from the Libby, Montana mine. If you have vermiculite in your attic, do not disturb it yourself. Our team handles vermiculite removal as a contained, careful process using HEPA-filtered vacuums and proper disposal protocols, and we test the material before removal whenever possible. Old batt insulation from the 1950s and 1960s often contains dust, rodent debris, and degraded paper backing that no longer serves any purpose except harboring allergens. We remove it, we document it, and we leave you with a written record of what was taken out and what went back in.
Insulation Replacement
Insulation replacement is what happens after removal: the installation of new material matched to your home’s thermal needs, our climate zone, and your budget. In Chicago, that means R-49 to R-60 in most attics, achieved with blown-in fiberglass from Owens Corning or Johns Manville, or with Rockwool batts where you want additional fire resistance and sound control. The new insulation is installed only after every top plate, can light, and plumbing penetration has been air sealed. You receive a written scope before work starts, a photo record during, and a blower-door number after that shows exactly what changed.

Brands We Service for Insulation Removal & Replacement
We remove and replace every major insulation brand installed in Chicago homes over the past 60 years, and we specify the right material for the replacement rather than pushing one manufacturer. Owens Corning blown-in fiberglass is our default recommendation for Chicago attics because it holds its loft, resists settling, and performs consistently in our freeze-thaw winters and humid summers. We regularly remove failed Owens Corning batt installations from the 1980s and 1990s and replace them with properly air-sealed, code-compliant systems.
Johns Manville and Knauf products also appear in our work regularly, particularly where homeowners want a recycled-content option or a specific R-value per inch. Rockwool stone wool is what we specify for sound control between floors in multi-unit buildings and for added fire resistance in garages and mechanical rooms. Whether you have an older brand we didn’t name here or a mixed-bag attic with three different materials from three different decades, we can remove it and replace it with a single, documented system. If you’re reading this from another market, our Insulation Removal & Replacement in Houston team handles the same scope of work down south.
Signs You Need Insulation Removal & Replacement Right Now
- Rodent activity in the attic. Droppings, nesting material, chewed wiring, or scratching sounds at night mean animals have been living in your insulation. Beyond the health concern, rodent-contaminated material compresses and loses thermal performance. We remove it, seal the entry points, and document the condition we found.
- Water staining on attic insulation or ceiling drywall. A roof leak soaks into insulation and begins a slow process of R-value loss and mold growth that most Chicago homeowners don’t notice until the heating bill climbs. Wet insulation never dries properly inside an attic cavity. It comes out, the leak gets fixed, and the attic gets rebuilt dry.
- Rising heating and cooling bills with no explanation. If your furnace and AC are running the same hours but your Peoples Gas or ComEd billing keeps climbing, your attic insulation may have compacted below functional levels. We see this in Chicago bungalows and split-levels built before 1980, where original insulation has settled to half its original depth.
- Rooms that never hold temperature. A bedroom that’s always 10 degrees colder in winter, a hallway that bakes in summer, ice dams forming on the roof edges: these are signs that warm air is escaping through the attic floor before it ever reaches the living space. The fix is removal, air sealing, and replacement, in that order.
- Dust, allergies, or unexplained odors. Old insulation breaks down into airborne particles that get pulled into the home through can light housings, attic hatches, and wall penetrations. If your indoor air smells stale or you’re dusting more than you used to, the attic is often the source. We remove the degraded material and the odor goes with it.
Our Insulation Removal & Replacement Process - Step by Step
- 1
Walkthrough and written price. We inspect the attic, take photos, measure square footage and current depth, and note every penetration, vent, and potential air leak. You get a flat written price with a written scope and written warranty before anyone starts. No exceptions. This is Haven Standard Clause 1.
- 2
Pre-removal blower-door test. We pressurize the house with a calibrated fan and record the CFM50 number: how many cubic feet per minute of air leak through the envelope at 50 pascals of pressure. This gives us a baseline. In Chicago, we regularly see 3,500 to 5,000 CFM50 on unsealed 1950s and 1960s homes.
- 3
Contained removal. The crew runs a high-volume vacuum system with the collection bag outside the house, removes all existing insulation down to the attic floor, and bags the material for disposal. Our technicians are background-checked, uniformed, and work with containment to keep the rest of your home clean.
- 4
Air sealing before insulation. Every top plate, can light, plumbing stack, bath fan, and wire penetration gets sealed with foam or caulk. This is the step most Chicago insulation companies skip because it’s tedious and invisible afterward. We won’t skip it. Air sealing is what makes the new insulation actually perform.
- 5
New insulation and post-work documentation. We blow or bat the new material to the R-value we specified in your written scope, run a second blower-door test, and show you both numbers side by side. You get a Documented Photo Record of the entire job and a written warranty. In Dallas, our Insulation Removal & Replacement in Dallas team follows the identical protocol.
How Much Does Insulation Removal & Replacement Cost in Chicago?
A typical attic insulation removal and replacement in Chicago runs $1,800 to $4,200 for a home between 1,200 and 2,200 square feet. Contaminated insulation removal adds $400 to $900 depending on the extent of the damage and the sanitization required. Vermiculite removal, which requires specialized handling and disposal, typically runs $2,500 to $6,000 when it’s present. And air sealing, which we do on every job, is included in the written price rather than being billed as a surprise line item.
Three factors move the number: the square footage of the attic, the type and condition of the existing material, and whether any structural repairs are needed after removal. A clean pull of standard fiberglass batts is fast. A tight Chicago bungalow with vermiculite, rodent damage, and a low-slope roof is a different job entirely. The way to avoid overpaying is to demand a written price, a written scope, and a written warranty before the work starts. You can also bring us any competitor’s written estimate and we’ll read it with you line by line. That’s our Free Second Opinion, and it’s been part of the Haven Standard since 2016.

Frequently Asked Questions - Insulation Removal & Replacement in Chicago
Insulation removal and replacement is the process of extracting old, compacted, or contaminated insulation from an attic or wall cavity and installing new material after the exposed surfaces have been air sealed. In Skokie and throughout Chicago, it’s most commonly performed in attics where decades of heat loss, roof leaks, or rodent activity have degraded the original material. At Topside Attic Insulation, the replacement always follows sealing, never precedes it.
Most Chicago attic removal and replacement jobs are completed in one to two working days. Contaminated jobs with sanitization can run three days, and vermiculite removal can add another day depending on the testing and disposal requirements.
