Fast, Reliable Attic Insulation Across Minneapolis
Most attic insulation jobs in a Minneapolis home run between $1,800 and $4,200 for blown-in coverage to R-49, and we complete the work the same day once the attic floor is air-sealed. That’s the part that matters here: sealing first, then insulating. Every crew that leaves our shop carries a blower door, not just a hose. If you live in Longfellow, Nokomis, or Northeast and you’re watching ice dams form on your eaves, call (218) 261-7714 for a written price before any work starts.
Why Topside Attic Insulation Is Minneapolis’s Preferred Attic Insulation Company
We’ve sealed and insulated more than 9,000 homes since 2016, and a large share of them sit in Minneapolis’s prewar neighborhoods. The houses change. The problem doesn’t. Minneapolis homeowners call us because we publish before-and-after blower-door numbers on every applicable job, which means you see the actual CFM50 drop-the measurement of air leakage through your building envelope-before you pay the final invoice. No other contractor treating insulation as a standalone product can do that, because you can’t verify sealed without measuring it.
Our techs know the difference between a Powderhorn bungalow’s balloon-framed walls and a 1990s tract house in the far southwest. That matters when the fix isn’t just more insulation. Wes Okafor, who leads our Minneapolis crews, has walked more Longfellow attics than he can count. He’ll tell you plainly whether your house needs dense-packing, blocking, or just a top-up. Reviews from Minneapolis customers consistently point to the same thing: the number on the blower door changed, and the ice dams stopped. Call (218) 261-7714 and a live person answers. No voicemail loops.
Our Attic Insulation Services in Minneapolis
Blown-In Attic Insulation
Blown-in fiberglass or cellulose is the standard retrofit for Minneapolis attics, and the material we use depends on what we find after air sealing. In a typical South Minneapolis bungalow, we blow Owens Corning AttiCat or GreenFiber cellulose to R-49, which is Minnesota’s code minimum. The job takes a day. The blower-door reading before and after tells you what changed. A typical blown-in job in Minneapolis runs $1,800-$3,800 depending on attic square footage, existing material, and access.
Attic Batt Insulation
Batt insulation makes sense when you have an open attic floor with consistent joist spacing and no existing material worth saving. We use Johns Manville and CertainTeed batts cut to fit, not jammed around obstructions. In Minneapolis attics with tight clearances near the eaves-common in low-slope bungalows-batt installation requires careful baffle placement first so the soffit vents can still pull air. Expect $2,200-$4,500 for a full batt job in a typical Minneapolis home.
Attic Insulation Top-Up
A top-up adds new insulation over existing material once we confirm the existing layer is dry, uncontaminated, and not covering active knob-and-tube wiring. This is the most common job we do in Minneapolis because so many homes got R-19 or R-30 years ago and never reached R-49. A top-up in Minneapolis runs $1,200-$2,800 typically. The important step happens before we blow a single bag: we air-seal the attic floor. Skipping that is why so many topped-up Minneapolis attics still produce ice dams.
Attic Insulation Replacement
When old insulation is compacted, water-stained, or riddled with rodent activity, it has to come out before new material goes in. We see this often in Minneapolis attics where a past roof leak soaked the insulation or where squirrels nested over a winter. Replacement in Minneapolis runs $3,000-$6,500 depending on size and access. We remove the old material, air-seal the attic floor, address any ventilation problems, and install new insulation to R-49. You get a photo record of the entire process.

Trusted Brands We Service in Minneapolis
We’re not tied to one manufacturer. Our Minneapolis crews work with Johns Manville, Knauf, and CertainTeed batt and blown-in products, plus GreenFiber cellulose and Owens Corning AttiCat when the job calls for it. That matters for you because we select the material that fits your attic’s existing conditions-not whatever we have a pallet of in the truck. If you have a warranty claim on existing insulation or need a specific product for an Xcel Energy rebate application, we’ll tell you straight whether it’s the right call. No proprietary product lock-in. We stock common materials locally, so a Minneapolis job rarely waits on a supply order.
Common Attic Insulation Problems We See in Minneapolis Homes
- Balloon-framed walls acting as flues. In pre-1940 bungalows across Longfellow, Powderhorn, and Northeast, the wall stud cavities run uninterrupted from basement rim joist to attic. Warm air rides those channels straight past your attic insulation and melts snow at the roof deck. The refreeze at the eaves is your ice dam.
- Knob-and-tube wiring buried under old insulation. A substantial share of South Minneapolis homes still have active knob-and-tube circuits in the attic floor. Blown-in insulation cannot be installed over live K&T, period. Xcel Energy rebates and most insurers require remediation first. We identify this before any work starts, not after.
- Attics insulated a decade ago that still produce ice dams. The previous contractor blew insulation over an unsealed attic floor. Top plates, can-light housings, and plumbing penetrations all leak air around the new insulation. The R-value looks fine. The air leakage isn’t. We see this failure mode every spring in Minneapolis.
- Missing or crushed baffles in low-slope attics. In dense urban Minneapolis neighborhoods with alley-access homes and tight roof pitches, contractors sometimes skip baffles to save time. Soffit vents get buried under insulation, moisture builds in the attic, and roof sheathing rots by spring. Our crew installs and verifies baffles before any insulation goes in.
Pricing for Attic Insulation in Minneapolis, MN
Here’s what you can expect in Minneapolis specifically. A blown-in top-up over existing insulation runs $1,200-$2,800 for a typical bungalow attic. Full blown-in insulation to R-49 runs $1,800-$3,800. Batt jobs run $2,200-$4,500. Full removal and replacement runs $3,000-$6,500.

FAQs - Attic Insulation in Minneapolis
Not necessarily. If your bungalow has balloon-framed walls-common in Longfellow, Powderhorn, and Northeast-the wall cavities act as warm-air flues from basement to attic. Adding insulation to the attic floor alone won’t stop the warm air bypassing it through the walls. The fix requires air sealing those channels, typically by dense-packing the stud cavities and installing blocking at the top plates, before any attic insulation is added. Call (218) 261-7714 for a written scope on what your specific house needs.
No, not over active knob-and-tube. Blown-in insulation cannot be installed over live K&T circuits. Xcel Energy rebate programs and most homeowner insurers require the wiring to be remediated before insulation can be added. We’ll identify K&T during our initial inspection and walk you through what needs to happen first. This is a common dead end for Minneapolis rebate seekers, and we’d rather tell you before you spend money on a job that gets flagged later.
Minnesota’s energy code requires R-49 in attic floors, which translates to roughly 14-16 inches of blown-in fiberglass or about 12-14 inches of cellulose, depending on settled density. Many older Minneapolis homes sit at R-19 or R-30 from decades-old work. We measure the existing depth during our inspection and tell you exactly what’s needed to hit R-49. A typical top-up in Minneapolis runs $1,200-$2,800. Call (218) 261-7714 for a written price on your attic.
The previous contractor likely blew insulation over an unsealed attic floor. Without air sealing first, warm interior air leaks through top plates, can lights, and plumbing penetrations and rises straight through the new insulation. The insulation blocks heat conduction but not air leakage. Our techs in Longfellow found a 1920s bungalow with a new attic blown-in job and a fresh ceiling stain under the eaves. We dense-packed the balloon-framed stud cavities with GreenFiber cellulose, installed blocking at the top plates, and then topped up the attic floor to R-49 with Owens Corning AttiCat after completing Reflectix repair in Minneapolis where needed. The next winter, the homeowner had no ice dams for the first time in years. The next winter, the homeowner had no ice dams for the first time in years. Bringing your attic from R-30 to R-49 without sealing is throwing money at the symptom. Call (218) 261-7714 and we’ll show you the blower-door numbers.
Yes. Our crews work in dense urban Minneapolis weekly, including alley-load homes in Whittier, Uptown, and the North Loop. Our trucks are standard cargo vans, not semis, and our techs are used to carrying material from the street or alley. Tight access doesn’t change our process: sealed first, then insulated, blower-door numbers before and after, and a documented photo record when we leave. Call (218) 261-7714 and tell us about your access situation. We’ll plan it before we arrive.
In most cases, we can schedule an inspection within 3-5 business days and complete the insulation work within one to two weeks, depending on scope and our Minneapolis schedule. Emergency ice dam related work-like urgent air sealing in a leaking attic-can often be prioritized when we have crews in your area. Call (218) 261-7714 and a live person will give you a real timeline, not a callback window.
