Insulation in Bloomington, MN
Spray foam insulation in Bloomington runs between $2.80 and $6.90 per board foot for most jobs, while blown-in attic work typically lands between $1,600 and $4,200 depending on depth and square footage. The city’s housing stock, mostly 1950s-1970s ramblers and split-levels with 2×4 framing, was built decades before Minnesota’s current R-49 attic and R-20 wall standards, so nearly every home we audit in Bloomington falls short. Call (218) 261-7714 for a written price before any work starts. We serve the entire Bloomington area from our Minneapolis-St Paul dispatch office.
Why Bloomington Homes Are Different
Bloomington sits directly under MSP International Airport’s primary flight corridors, and the Metropolitan Airports Commission’s Residential Sound Insulation Program has treated thousands of local homes with acoustic packages: new windows, doors, and sound-sealing. Homeowners often assume that work covered thermal insulation too. It usually didn’t. We routinely walk into Bloomington attics that look “done” from a sound-program upgrade but still read R-11 and have uninsulated rim joists. That gap between acoustic treatment and thermal performance is the single most common misunderstanding we correct here.
The housing stock compounds it. Bloomington was developed intensively from the early 1950s through the mid-1970s, leaving a dominant pattern of single-story ramblers and split-levels. Those homes have shallow attic cavities, 2×4 exterior walls, and either slab-on-grade or vented crawlspace foundations. Split-levels from the 1960s boom often carry a hidden problem: the mid-level band joist, the framed wall between lower and upper floors, was frequently left completely uninsulated and sits exposed inside a tuck-under garage. That creates a thermal bridge we check on every Bloomington split-level we touch. Add roughly 8,000 heating degree days a year and the flat Minnesota River basin offering little windbreak, and low-slope rambler rooflines become chronic ice-dam generators each winter.
Our Main Bloomington Services
Two jobs dominate the call sheet in Bloomington: attic insulation retrofits driven by ice dams and high heating bills, and crawl space encapsulation in homes where moisture from the river basin works up through vented foundations. Here is what each involves locally.
Attic Insulation in Bloomington
Most Bloomington ramblers and split-levels carry R-11 to R-19 in the attic, far below the R-49 the current Minnesota energy code requires. We remove or top up what’s there, air seal the attic floor first, and blow to the specified depth, documenting before-and-after blower-door readings on every applicable job. Attic Insulation in Bloomington goes deeper on pricing, permits, and what the job looks like in a 1960s split-level.
Crawl Space Encapsulation & Vapor Barrier in Bloomington
Vented crawlspaces in Bloomington pull damp air from the flat, low-lying ground around the Minnesota River basin, which feeds humidity into the living space above. Encapsulation means sealing the floor and walls, managing groundwater, and conditioning the air so the crawlspace stops acting like a moisture pump. Crawl Space Encapsulation & Vapor Barrier in Bloomington details the full scope and typical local pricing.

Spray Foam Insulation in Bloomington
Spray foam in Bloomington solves the two problems this housing stock hands us most often: uninsulated rim joists in 1960s split-levels and shallow roof cavities in low-slope ramblers that ice up every winter. Closed-cell foam at 2 inches adds R-14 and acts as an air barrier, which matters in a city where 8,000 heating degree days punish every gap. Our Spray Foam Insulation service covers the full material and application line, and every Bloomington job starts with a written price. We spray Owens Corning and Demilec products among the materials we source, never locking you into one brand.
Rim Joist Spray Foam
Signs you need it
If the band joist in your tuck-under garage is exposed and you can feel cold air or see daylight at the sill, the rim joist is uninsulated.
What it costs in Bloomington
Rim joist spray foam in Bloomington typically runs $4.20-$6.90 per board foot for closed-cell foam including prep and cleanup.
How we do it
We remove any batt material, prep the sill area, and spray closed-cell foam to a minimum 2-inch depth across the full rim joist perimeter.
Closed-Cell Spray Foam
Signs you need it
If your attic floor is shallow and you need maximum R-value per inch, or your roof deck is leaking heat and causing ice dams, closed-cell is the fit.
What it costs in Bloomington
Closed-cell spray foam in Bloomington runs $4.20-$6.90 per board foot installed, not including surface prep or removal of existing insulation.
How we do it
We mask and ventilate the work area, spray foam to the specified depth, let it cure, then document the finished thickness and coverage with photos.
What Spray Foam Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Open-cell spray foam | $2.80-$5.20 per board foot |
| Closed-cell spray foam | $4.20-$6.90 per board foot |
| Rim joist spray foam (closed-cell) | $1,200-$2,600 per typical split-level |
Is closed-cell worth the extra cost in Bloomington?
Yes, usually. Closed-cell adds R-value per inch, acts as a vapor retarder, and adds structural strength, which helps in shallow rambler roof cavities where open-cell won’t meet code. Call (218) 261-7714 for a written quote.
Can you spray foam an occupied Bloomington home?
Yes. We contain the work area, ventilate during application, and schedule around your household. Occupants leave for a few hours during spray and cure, then return without issue.
Blown-In Insulation in Bloomington
Blown-in insulation in Bloomington is the most common retrofit we do in 1950s and 1960s ramblers and split-levels where attics were originally insulated to R-11 or R-19, far below Minnesota’s current R-49 requirement. The depth is shallow, the floor is usually punctured with can lights and top plates that leak conditioned air, and the low-slope rooflines make ice dams a recurring winter problem. Our Blown-In Insulation crew air seals before blowing, every time, and documents the before-and-after blower-door result on applicable jobs.
Blown-In Cellulose
Signs you need it
If your attic insulation measures under 6 inches deep, you’re at R-19 or less and losing heat through the ceiling all winter.
What it costs in Bloomington
Blown-in cellulose in Bloomington typically costs $1,600-$3,800 for a 1,200-1,800 sq ft attic depending on existing depth and target R-value.
How we do it
We air seal the attic floor, set depth markers, and blow GreenFiber cellulose to the specified R-value, then photograph the finished coverage.
Blown-In Top-Up
Signs you need it
If you have some insulation but it’s settled below R-30, a top-up to R-49 brings you current without full removal.
What it costs in Bloomington
A blown-in top-up in Bloomington typically runs $1,200-$2,800 depending on the existing depth and attic square footage.
How we do it
We verify the existing material is dry and uncontaminated, air seal gaps, then blow to the code-required R-49, documenting final depth in photos.
What Blown-In Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Blown-in cellulose (full attic) | $1,600-$3,800 |
| Blown-in fiberglass (full attic) | $1,800-$4,200 |
| Blown-in top-up | $1,200-$2,800 |
Can you blow insulation over existing attic insulation in Bloomington?
Yes, if the existing material is dry and uncontaminated. We verify condition first, then top up to R-49. If it’s compressed or damp, removal is the better route.
How long does blown-in attic insulation take in Bloomington?
Most Bloomington attics are done in one day: air sealing in the morning, blowing in the afternoon, photos and documentation by end of day. Call (218) 261-7714 for scheduling.
Radiant Barrier Installation in Bloomington
Radiant barrier in Bloomington goes into the same 1950s-1970s rambler attics that also need air sealing and blown-in insulation. The flat river basin gives these homes little wind relief, and roof decks absorb full summer sun, so a foil barrier on the rafters or roof deck cuts radiant heat gain into the attic. Our Radiant Barrier Installation team staples the material to the underside of rafters or roof deck; it works best alongside proper attic ventilation, not as a substitute for insulation.
Attic Radiant Barrier
Signs you need it
If your second floor or upper level runs 8-10 degrees warmer than the main floor in July, the roof deck is radiating heat into your attic.
What it costs in Bloomington
Attic radiant barrier in Bloomington typically runs $1,100-$2,900 for a 1,200-1,800 sq ft attic depending on roof pitch and access.
How we do it
We staple perforated foil to the underside of the rafters or roof deck, leaving a ventilation gap at soffits and ridge, and document the full coverage with photos.
Radiant Barrier Roof Deck
Signs you need it
If your attic is unconditioned and your roof deck reads hot to the touch in summer, a roof-deck barrier blocks heat before it enters the space.
What it costs in Bloomington
Radiant barrier roof deck application in Bloomington runs $1,100-$2,400 for typical rambler rooflines with standard access.
How we do it
We install the foil directly to the roof deck underside, securing it so it won’t trap moisture, and confirm ventilation paths stay open.
What Radiant Barrier Installation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic radiant barrier (stapled) | $1,100-$2,900 |
| Radiant barrier roof deck | $1,100-$2,400 |
| Radiant barrier with ventilation correction | $1,400-$2,900 |
Does radiant barrier help in Bloomington winters?
Radiant barrier works mainly in summer by blocking radiant heat from the roof deck. In Minnesota winters, it adds marginal benefit; your bigger return comes from air sealing and insulation depth.
Can you install radiant barrier with existing insulation?
Yes. Radiant barrier goes on the rafters or roof deck, not on the attic floor, so it doesn’t interfere with existing blown-in insulation. Call (218) 261-7714 for a written price.
Insulation Removal & Replacement in Bloomington
Insulation removal and replacement in Bloomington most often comes up two ways: a 1960s split-level with original batt insulation that has settled, compacted, or been contaminated by rodents, or an attic that got a sound-program upgrade years ago but never touched the thermal layer. We remove the old material fully, clean and sanitize the space, then install new insulation to current code. Our Insulation Removal & Replacement process includes a written scope and photos before and after.
Attic Insulation Removal
Signs you need it
If your attic insulation is compressed, damp, or packed with rodent droppings, removal is the right call before adding anything new.
What it costs in Bloomington
Attic insulation removal in Bloomington typically runs $2,000-$4,200 for a 1,200-1,800 sq ft attic, not including new insulation.
How we do it
We use a high-powered vacuum system to extract the old material, bag it for disposal, then prep the attic floor for air sealing.
Contaminated Insulation Removal
Signs you need it
If you see droppings, urine staining, or nesting material in the insulation, the material is contaminated and needs full removal, not a top-up.
What it costs in Bloomington
Contaminated insulation removal in Bloomington runs $2,600-$5,200 depending on the extent of contamination and the attic size.
How we do it
We remove all contaminated material, sanitize the space, seal entry points, and document everything before new insulation goes in.
What Insulation Removal & Replacement Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic insulation removal | $2,000-$4,200 |
| Contaminated insulation removal | $2,600-$5,200 |
| Vermiculite or old insulation removal | $3,200-$6,800 |
Do you test for asbestos before removing old insulation in Bloomington?
If we suspect vermiculite or any material that might contain asbestos, we stop and recommend testing before removal. We never disturb suspicious material without confirmation it’s safe to handle.
How long does full insulation replacement take in Bloomington?
Most Bloomington attics are fully removed and replaced in one to two days. The removal is the longer part; new blown-in installation usually finishes the same afternoon. Call (218) 261-7714 for specifics.
Attic Air Sealing in Bloomington
Attic air sealing in Bloomington is the prerequisite we won’t skip, and it’s the single highest-return job for homes under the airport flight corridors. The sound-program homes often have sealed windows but completely leaky top plates and can lights, so conditioned air pours into the attic all winter. Our Attic Air Sealing crew seals every penetration before any insulation goes in, and we publish the before-and-after blower-door numbers on applicable jobs so you can see the result in one figure.
Top Plate & Penetration Sealing
Signs you need it
If you see dirty insulation around the attic perimeter or around plumbing and electrical penetrations, conditioned air has been leaking through those gaps.
What it costs in Bloomington
Top plate and penetration sealing in Bloomington typically runs $1,200-$2,000 for a standard rambler attic.
How we do it
We seal the gap between drywall and framing at every top plate, then foam or caulk each plumbing, electrical, and duct penetration.
Can Light & Duct Boot Sealing
Signs you need it
If your recessed can lights are warm to the touch or you feel drafts around ceiling fixtures, they’re leaking conditioned air into the attic.
What it costs in Bloomington
Can light and duct boot sealing in Bloomington runs $800-$1,600 depending on fixture count and accessibility.
How we do it
We install sealed covers over non-IC-rated fixtures and seal the gap between each duct boot and the drywall with foam or mastic.
What Attic Air Sealing Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic floor air sealing (full attic) | $1,500-$2,800 |
| Top plate & penetration sealing | $1,200-$2,000 |
| Can light & duct boot sealing | $800-$1,600 |
Why do you seal before you insulate in Bloomington?
Because blowing insulation over an unsealed attic floor buries the leaks without fixing them. Sealed first, then insulated: the air sealing is what changes your blower-door number, not the fiberglass.
Can you air seal my Bloomington attic in one day?
Yes. Most Bloomington attics are air sealed in a single day, with insulation following immediately after. Call (218) 261-7714 to schedule both together for the best result.
Wall Insulation in Bloomington
Wall insulation in Bloomington addresses what’s behind the drywall in thousands of 2×4-framed ramblers and split-levels built between the early 1950s and mid-1970s: nothing, or a thin layer of settled fiberglass. Minnesota code now requires R-20 in walls, but these homes rarely exceed R-11. Our Wall Insulation work includes drill-and-fill and injection foam options, and we can inspect the cavity condition before quoting.
Drill & Fill Wall Insulation
Signs you need it
If your walls feel cold to the touch in January and heating bills keep climbing, the cavities are likely uninsulated or under-insulated.
What it costs in Bloomington
Drill and fill wall insulation in Bloomington typically runs $3,400-$7,800 for a full exterior wall package on a rambler or split-level.
How we do it
We drill small access holes through the exterior or interior finish, blow dense-pack cellulose or inject foam into each cavity, then patch and document.
Injection Foam Wall Insulation
Signs you need it
If your wall cavities are partially insulated with settled batts, injection foam fills the voids without removing drywall.
What it costs in Bloomington
Injection foam wall insulation in Bloomington runs $4,200-$9,600 for typical single-story homes depending on wall area and access.
How we do it
We inject slow-rise foam into each stud bay through small openings, letting it expand to fill the cavity, then confirm coverage with thermal imaging.
What Wall Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Drill & fill wall insulation (full home) | $3,400-$7,800 |
| Injection foam wall insulation | $4,200-$9,600 |
| Interior wall soundproofing | $1,600-$3,800 |
Can you insulate walls without removing drywall in Bloomington?
Yes. Drill-and-fill and injection foam both go in through small holes, not full drywall removal. We patch and clean up so the finished surface looks untouched.
Do Bloomington homes with 2×4 walls need special insulation?
2×4 walls max out around R-15 with closed-cell foam, which still beats nothing. We quote what the cavity will actually hold, not a theoretical number. Call (218) 261-7714 for a written price.
Attic Cleaning & Rodent Proofing in Bloomington
Attic cleaning and rodent proofing in Bloomington handles the aftermath of mice and squirrels that move into 1960s split-level attics through gaps at soffits, roof vents, and the exposed mid-level band joist in tuck-under garages. The flat river basin gives rodents easy ground cover and plenty of entry routes. Our Attic Cleaning & Rodent Proofing process removes the contaminated material, sanitizes, seals entry points, and documents everything with photos.
Attic Cleanout
Signs you need it
If you see droppings, nesting, or damaged insulation in the attic, the material needs removal and the space needs cleaning before anything else.
What it costs in Bloomington
Attic cleanout in Bloomington typically runs $1,800-$3,600 for a standard rambler or split-level attic.
How we do it
We remove all contaminated insulation and debris, vacuum the space, and prepare it for sanitizing or new insulation.
Rodent Proofing & Exclusion
Signs you need it
If you hear scratching at night or find fresh droppings after cleaning, animals are still getting in through unsealed entry points.
What it costs in Bloomington
Rodent proofing and exclusion in Bloomington runs $900-$2,400 depending on the number of entry points and roof complexity.
How we do it
We identify every entry point, seal it with metal flashing and exclusion material, and confirm the attic is animal-tight before finishing.
What Attic Cleaning & Rodent Proofing Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic cleanout (full) | $1,800-$3,600 |
| Attic sanitizing & decontamination | $1,200-$2,800 |
| Rodent proofing & exclusion | $900-$2,400 |
Do you handle the rodents or just the insulation in Bloomington?
We handle exclusion: sealing the entry points so animals can’t get back in. We don’t trap or poison. Once the space is sealed and clean, we install new insulation if you want it.
How soon can you clean my Bloomington attic after rodents are found?
Usually within a few days of your call. We remove contaminated material first, then sanitize and seal so the problem doesn’t repeat. Call (218) 261-7714 to schedule.
Home Energy Audit in Bloomington
A home energy audit in Bloomington gives you the one number that matters: blower-door CFM50, the measurement of how much air your envelope leaks. For homes under the MSP flight corridors that got sound-program upgrades, the test often reveals that the windows and doors are tight but the attic floor and band joists leak badly. Our Home Energy Audit includes a full walkthrough, blower door test, thermal imaging, and a written report with prioritized recommendations.
Blower Door Test
Signs you need it
If your heating bills are high but the house doesn’t feel drafty, a blower door test finds the leaks you can’t feel.
What it costs in Bloomington
A blower door test in Bloomington runs $450-$1,200 depending on home size and whether it’s bundled with other audit services.
How we do it
We mount a calibrated fan in an exterior door frame, depressurize the house, and measure air leakage in CFM50, then walk the home to find each leak.
Thermal Imaging Inspection
Signs you need it
If certain rooms run cold in winter or hot in summer, thermal imaging shows exactly where insulation is missing or air is moving through the walls.
What it costs in Bloomington
Thermal imaging inspection in Bloomington runs $350-$900 as a standalone service, often less when bundled with a blower door test.
How we do it
We scan interior and exterior surfaces with an infrared camera while the house is depressurized, then document every anomaly with photos.
What Home Energy Audit Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Blower door test (standalone) | $450-$1,200 |
| Thermal imaging inspection | $350-$900 |
| Full energy audit (blower door + thermal + report) | $950-$2,800 |
Do I need an energy audit before insulating my Bloomington home?
Not always, but an audit tells you what to fix first and gives you a baseline CFM50 number to compare against after the work. You’ll know what you paid for. Call (218) 261-7714.
What do I get from a Bloomington energy audit?
You get a written report with the blower-door number, thermal images, insulation findings, and a prioritized list of fixes. We leave documentation, not a verbal summary.

FAQs About Insulation in Bloomington
We typically schedule estimates within one to two business days in Bloomington, and emergency work like a rodent-contaminated attic can often start within the same week. Calls are answered by a live person 24/7, not a voicemail loop.
Most insulation retrofits in Bloomington don’t require a permit, but air sealing and insulation combined with structural changes sometimes do. We verify the scope against city requirements and handle paperwork when a permit is needed.
