Insulation in Bloomington, MN
Crawl space encapsulation and vapor barrier work in Bloomington usually runs between $3,200 and $8,500 depending on square footage and access, and most jobs are completed in one to two days. Bloomington’s mix of 1950s-1970s ranch homes, the Minnesota River valley’s damp southern microclimate, and winter lows near -20°F makes this work more urgent here than in newer suburbs. If you’re noticing musty smells or cold floors, call Walt’s Insulation at (866) 751-4428 and a real person answers, day or night.
Why Bloomington Homes Are Different
Bloomington suburbanized in a burst between roughly 1952 and 1975, which left a deep inventory of ranch and split-level homes built before Minnesota had meaningful residential energy codes. Attics in these houses often still carry the original fiberglass batts, now compressed and settled to R-8 or less, far below the R-49 the state now requires. Slab-on-grade construction and unfinished basements are common here too, meaning many homes have zero foundation-wall or rim-joist insulation.
Climate makes it worse. The Twin Cities metro sees about 8,000 to 8,500 heating degree days annually, and Bloomington regularly drops to -15°F or -20°F overnight in January. Poorly air-sealed attic bypasses and uninsulated rim joists become direct heat-loss and ice-dam drivers on the low-slope rooflines typical of the area’s ranch homes. South of I-494 near the Minnesota River, the air stays damp, accelerating vapor-barrier degradation in older crawl spaces and slab perimeters.
And then there’s the airport factor, which is unique to Bloomington. Northern and central neighborhoods fall under MSP flight paths, and the Metropolitan Airports Commission’s Sound Insulation Program has upgraded windows and wall assemblies in thousands of homes. Those houses have new sound-dampening wall systems but often still carry the original attic insulation. Homeowners assume the airport program insulated everything. It didn’t, and we find that mismatch constantly.
Our Main Bloomington Services
Two jobs dominate the calls we get from Bloomington homeowners. One is the MAC-treated-house retrofit gap, and the other is crawl space work driven by the river valley’s damp air.
Attic Insulation in Bloomington
In the MAC sound-treatment zone north of I-494 between Penn Avenue and Lyndale, we regularly open attic hatches and find brand-new interior storm windows and insulated exterior doors paired with original cellulose or fiberglass that has settled to R-8 or less. The house looks insulated. The thermal envelope isn’t. We blow in fresh insulation to R-49, air seal first, and the heating bills drop. See Attic Insulation in Bloomington for the full breakdown.

Crawl Space Encapsulation & Vapor Barrier in Bloomington
Crawl space encapsulation in Bloomington usually costs between $3,200 and $8,500, with most jobs running $4,500 to $6,500 for a standard ranch footprint. The southern edge of the city along the Minnesota River creates a moisture-laden microclimate that accelerates vapor-barrier failure, so we treat this as a year-round problem here, not a spring-only one. Our full Crawl Space Encapsulation & Vapor Barrier service covers the liner, sealing, and insulation as one system, because half-measures fail fast in Bloomington’s clay-heavy, damp soils.
Crawl Space Vapor Barrier
Signs you need it
Musty smell drifting up through the floor, condensation on ductwork, or visible damp soil under the house.
What it costs in Bloomington
A 6-mil or 10-mil vapor barrier for a standard Bloomington crawl space runs $1,500-$3,000, and a 12-mil reinforced liner with taped seams runs $2,500-$4,500.
How we do it
We clear the floor, lay the liner up the foundation walls, seal every seam, and mechanically fasten it so it stays put through Bloomington’s freeze-thaw cycles.
Crawl Space Encapsulation
Signs you need it
Floor joists showing mold streaks, insulation sagging from the subfloor, or a crawl space that never dries out after rain.
What it costs in Bloomington
Full encapsulation, including sealing vents, foundation wall coverage, and a dehumidifier prep, runs $4,000-$8,500 in Bloomington.
How we do it
We seal the space from outside air, line the floor and walls, insulate the rim, and leave you a dry, conditioned space that doesn’t fight your HVAC.
Crawl Space Insulation
Signs you need it
Cold floors in winter, frozen plumbing along exterior walls, or a crawl space that radiates cold into the living space.
What it costs in Bloomington
Adding closed-cell spray foam to rim joists plus floor insulation runs $1,800-$3,200 depending on crawl space square footage.
How we do it
We insulate rim joists with closed-cell foam and install batts or foam board against the foundation walls, then seal the band joist area.
What Crawl Space Encapsulation & Vapor Barrier Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Vapor barrier (6-10 mil) | $1,500-$3,000 |
| Vapor barrier (12 mil reinforced) | $2,500-$4,500 |
| Full encapsulation | $4,000-$8,500 |
| Crawl space insulation | $1,800-$3,200 |
Can you fix a damp crawl space in Bloomington without digging?
Yes. Encapsulation doesn’t require excavation; we work from inside the crawl space, sealing and lining from within, which keeps costs down and avoids disturbing your yard.
Will encapsulation stop my wood floors from cupping?
Usually. Cupping is moisture migrating upward from the crawl space. Once the liner and sealing are in place, the moisture source is gone. Call (866) 751-4428 for a look.
Spray Foam Insulation in Bloomington
Spray foam insulation in Bloomington runs $1.50 to $3.50 per board foot for open-cell and $2.50 to $5.50 for closed-cell, with rim joist jobs starting around $800. On the ranch homes that dominate Bloomington’s 1950s-era neighborhoods, rim joists are the single biggest air leak we find, and closed-cell foam seals them permanently. Our Spray Foam Insulation work uses Icynene and Demilec products when the job calls for them, because foam quality matters in -20°F winters.
Closed-Cell Spray Foam
Signs you need it
Ice dams forming at the roof edge, drafty rooms over the garage, or rim joists you can feel cold air moving through.
What it costs in Bloomington
Closed-cell foam in Bloomington runs $2.50-$5.50 per board foot, with a typical rim joist package at $1,200-$2,400.
How we do it
We clean the surface, apply the foam in lifts to the target depth, and trim it flush before it fully cures.
Rim Joist Spray Foam
Signs you need it
Drafty baseboards on the main floor, higher heating bills than neighbors with similar homes, or mouse activity around the sill plate.
What it costs in Bloomington
A typical Bloomington ranch’s rim joist package runs $800-$1,800, depending on footage and access.
How we do it
We seal around the sill, spray a continuous bead of closed-cell foam across the band joist, and let it expand to fill every seam.
What Spray Foam Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Open-cell spray foam (per board foot) | $1.50-$3.50 |
| Closed-cell spray foam (per board foot) | $2.50-$5.50 |
| Rim joist spray foam | $800-$1,800 |
| Garage ceiling spray foam | $1,600-$3,200 |
Is spray foam worth it in Bloomington’s cold climate?
Yes, especially on rim joists and band joists. Closed-cell foam adds R-value and stops air movement, which is the bigger energy thief in Bloomington winters. Most homeowners see the payback in two to four heating seasons.
Can you spray foam an attic in an older Bloomington ranch?
Yes, we spray foam roof decks in older ranches regularly. It works best when we air seal first, but the foam seals the deck and stops the air movement through the original construction gaps. Call (866) 751-4428 to schedule an assessment.
Blown-In Insulation in Bloomington
Blown-in insulation in Bloomington typically costs $1,800 to $4,500 for a full attic top-up to R-49, with cellulose at the lower end and fiberglass slightly higher. In the MAC-treated neighborhoods north of I-494, the retrofit gap is stark: sound-dampening windows and walls sitting over settled, original attic insulation, often at R-8 or less. Our Blown-In Insulation work uses GreenFiber cellulose and CertainTeed fiberglass, and we air seal before we blow.
Blown-In Cellulose
Signs you need it
Visible settling in the attic, rooms that heat unevenly, or an attic floor you can see bare patches on.
What it costs in Bloomington
Blown-in cellulose to R-49 in a typical Bloomington attic runs $1,800-$3,400.
How we do it
We air seal the attic floor, mark target depths, and blow cellulose to a consistent R-49 across the entire floor.
Blown-In Top-Up
Signs you need it
Existing attic insulation that measures under R-30, or uneven coverage with thin spots near the eaves.
What it costs in Bloomington
Top-up blown-in insulation over existing material in Bloomington runs $1,200-$2,500 depending on square footage.
How we do it
We check the existing material for moisture or rodent damage first, then blow fresh fiberglass or cellulose over it to R-49.
What Blown-In Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Blown-in cellulose (full attic) | $1,800-$3,400 |
| Blown-in fiberglass (full attic) | $2,200-$4,500 |
| Blown-in top-up | $1,200-$2,500 |
| Dense-pack wall insulation | $2,500-$5,000 |
How do I know if my Bloomington attic has enough insulation?
Measure it. If you have less than 14 inches of fiberglass or cellulose, you’re below R-49 and leaving heat on the table. We’ll check it for free as part of any estimate.
Does blown-in insulation settle over time in Bloomington’s cold?
Cellulose settles slightly in the first year and then stabilizes. Fiberglass settles less. We account for settlement with the initial depth we install. Call (866) 751-4428 for exact numbers.
Radiant Barrier Installation in Bloomington
Radiant barrier installation in Bloomington runs $1,500 to $4,500 for a typical attic, with roof deck applications at the higher end. Bloomington’s ranch homes with dark shingle roofs absorb serious summer heat, and a radiant barrier under the roof deck cuts attic temperatures by 20 to 30 degrees, which takes real load off your air conditioner. Our Radiant Barrier Installation uses foil-faced material stapled to the rafters, leaving the ridge and soffit vents open so the attic still breathes.
Attic Radiant Barrier
Signs you need it
An upstairs that won’t cool below 80°F in July, an air conditioner that runs nonstop, or attic temperatures you can feel radiating through the ceiling.
What it costs in Bloomington
A radiant barrier across a standard Bloomington attic floor runs $1,500-$3,000.
How we do it
We staple the foil to the underside of the roof deck, keeping it slightly off the deck so the reflective surface does its job.
Radiant Barrier & Ventilation
Signs you need it
Attic heat problems combined with inadequate soffit or ridge vents, or moisture accumulation in the attic during winter.
What it costs in Bloomington
Radiant barrier plus ventilation correction in Bloomington runs $2,800-$4,500.
How we do it
We install the barrier and check the full ventilation path, adding baffles or correcting blocked soffit vents so the attic works as a system.
What Radiant Barrier Installation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic radiant barrier | $1,500-$3,000 |
| Radiant barrier roof deck | $2,800-$4,500 |
| Radiant barrier & ventilation | $2,800-$4,500 |
Does a radiant barrier help in winter in Bloomington?
A little. Radiant barriers are primarily a summer product, but they also reduce heat loss through the roof at night by reflecting heat back into the living space. The bigger winter win is air sealing and insulation.
Can I install a radiant barrier with existing attic insulation?
Yes. The barrier goes on the roof deck or attic floor, not in contact with the existing insulation. We install it without disturbing the R-value you already have. Call (866) 751-4428 for an attic assessment.
Insulation Removal & Replacement in Bloomington
Insulation removal and replacement in Bloomington runs $2,000 to $6,000, with vermiculite or contaminated jobs at the higher end. Older Bloomington homes often have original batts that have been soaked by roof leaks, packed down by decades of rodent traffic, or contaminated by a bat colony. Our Insulation Removal & Replacement team vacuums everything out, sanitizes the attic, air seals, and reinstalls fresh insulation to R-49.
Attic Insulation Removal
Signs you need it
Insulation that’s black or matted, visible rodent droppings throughout, or a history of roof leaks.
What it costs in Bloomington
Attic insulation removal for a standard Bloomington ranch runs $2,000-$4,000.
How we do it
We run a high-powered vacuum from the attic to a truck, removing old batts, loose fill, and debris in a single pass.
Contaminated Insulation Removal
Signs you need it
Animal nesting, urine staining, or mold growth visible on the insulation surface.
What it costs in Bloomington
Contaminated insulation removal with sanitizing runs $2,500-$4,500 in Bloomington.
How we do it
We remove all contaminated material, fog the space with an antimicrobial, and prep the attic for fresh insulation.
What Insulation Removal & Replacement Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic insulation removal | $2,000-$4,000 |
| Contaminated insulation removal | $2,500-$4,500 |
| Vermiculite removal | $2,500-$6,000 |
| Insulation replacement (removal + new) | $3,500-$6,000 |
How do I know if my Bloomington attic insulation needs replacing?
If it’s matted flat, smells, or shows staining, it’s done. Insulation only works when it’s dry, clean, and fluffed. We’ll tell you honestly if a top-up is enough or full removal is needed.
Can you remove old vermiculite from a Bloomington attic?
Yes, we handle vermiculite removal carefully with the right containment and PPE. It’s a specialized job, and we follow safe handling protocols end to end. Call (866) 751-4428 to discuss your attic.
Attic Air Sealing in Bloomington
Attic air sealing in Bloomington runs $800 to $2,500, and it’s the single most cost-effective energy improvement for the city’s 1950s-1970s ranch homes. On low-slope rooflines, every unsealed bypass lets warm interior air hit the cold roof deck, which is exactly how ice dams form. Our Attic Air Sealing service seals top plates, penetrations, can lights, duct boots, and the attic hatch before any insulation goes down.
Attic Floor Air Sealing
Signs you need it
Ice dams forming every winter, dust lines on attic insulation showing air movement, or rooms that won’t hold heat.
What it costs in Bloomington
Attic floor air sealing in a typical Bloomington ranch runs $800-$1,800.
How we do it
We pull back the existing insulation, seal every seam and penetration with foam or caulk, and relay the insulation.
Attic Hatch Sealing
Signs you need it
A hatch that’s warm to the touch in winter, cold drafts in the hallway below, or visible gaps around the hatch frame.
What it costs in Bloomington
Attic hatch sealing with a weather-stripped cover runs $250-$500 in Bloomington.
How we do it
We add a gasketed frame, weather-stripping, and an insulated cover so the hatch stops acting like an open chimney.
What Attic Air Sealing Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic floor air sealing | $800-$1,800 |
| Top plate & penetration sealing | $600-$1,400 |
| Can light & duct boot sealing | $400-$900 |
| Attic hatch sealing | $250-$500 |
Why is my Bloomington house still cold after adding insulation?
Because insulation slows heat loss but doesn’t stop air movement. If your attic bypasses aren’t sealed, warm air leaks out and insulation underperforms. Air sealing first is the fix.
Can you air seal an attic without removing the old insulation?
Yes. We work around existing insulation by pulling it back in sections, sealing underneath, and relaying it. The job is clean and fast. Call (866) 751-4428 for a site visit.
Wall Insulation in Bloomington
Wall insulation in Bloomington runs $2,500 to $8,500 depending on whether we’re drilling and filling finished walls, injecting foam, or insulating during a remodel. The MAC sound program upgraded many Bloomington wall assemblies, but homes outside that zone, especially south-side ranches and split-levels built before 1975, often have empty or thin wall cavities. Our Wall Insulation work uses drill-and-fill cellulose or injection foam, and we patch everything so you can’t tell we were there.
Injection Foam Wall Insulation
Signs you need it
Walls cold to the touch in winter, rooms that never warm evenly, or exterior walls that sweat in summer.
What it costs in Bloomington
Injection foam wall insulation for a standard Bloomington ranch’s exterior walls runs $3,000-$6,500.
How we do it
We drill small access holes from inside or outside, inject foam that expands to fill the cavity, and patch the holes.
Interior Wall Soundproofing
Signs you need it
Noise from a busy road, a home office that needs quiet, or a shared wall that carries sound between rooms.
What it costs in Bloomington
Interior wall soundproofing with dense-pack cellulose or mineral wool runs $1,800-$3,500 for a standard wall run.
How we do it
We dense-pack the wall cavities with sound-dampening material and seal any flanking paths around outlets and baseboards.
What Wall Insulation Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Injection foam wall insulation | $3,000-$6,500 |
| Drill & fill wall insulation | $2,500-$5,000 |
| Exterior wall insulation | $5,000-$8,500 |
| Interior wall soundproofing | $1,800-$3,500 |
Can you insulate existing walls without tearing them open?
Yes. Drill-and-fill and injection foam both go through small holes that we patch afterward. The walls stay intact. Call (866) 751-4428 for a wall assessment.
Will wall insulation stop drafts in my Bloomington home?
Mostly. Drafts usually come from air leaks at baseboards, outlets, and rim joists. Wall insulation helps, but air sealing the rim and floor is the full fix.
Attic Cleaning & Rodent Proofing in Bloomington
Attic cleaning and rodent proofing in Bloomington runs $1,200 to $4,500 depending on contamination level and attic size. Bloomington’s older ranch homes with accessible soffit gaps and unscreened vents are prime entry points for squirrels and mice, and the damage to insulation happens fast. Our Attic Cleaning & Rodent Proofing service removes the waste, sanitizes the space, seals entry points, and gets the attic ready for fresh insulation.
Attic Sanitizing & Decontamination
Signs you need it
Rodent droppings, urine staining, or a persistent odor you can smell from the hallway below.
What it costs in Bloomington
Attic sanitizing and decontamination in a standard Bloomington attic runs $600-$1,500.
How we do it
We remove contaminated material, fog with an antimicrobial, and leave the surfaces clean and safe to re-insulate.
Rodent Proofing & Exclusion
Signs you need it
Scratching sounds in the attic at night, gnawed wires or wood, or insulation tunnels showing animal traffic.
What it costs in Bloomington
Rodent proofing and exclusion around the roofline and foundation in Bloomington runs $800-$2,000.
How we do it
We find every entry point, seal it with steel mesh or foam, and make sure the roof, soffits, and vents are closed off.
What Attic Cleaning & Rodent Proofing Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Attic cleanout | $1,200-$2,500 |
| Attic sanitizing & decontamination | $600-$1,500 |
| Rodent proofing & exclusion | $800-$2,000 |
| Attic restoration (full) | $2,500-$4,500 |
How do rodents get into Bloomington attics?
Mostly through unscreened soffit vents, gaps at the roof-wall junction, and open chase ways. Older ranch homes with simple roof lines have plenty of these. Sealing them is the only permanent fix.
Do you handle the rodents or just clean up after them?
We handle exclusion: closing the entries so they can’t get back in. We don’t trap, but once the entry points are sealed, the problem stops. Call (866) 751-4428 to discuss your attic.
Home Energy Audit in Bloomington
A home energy audit in Bloomington runs $300 to $600 for a full blower door and thermal imaging assessment, and in many cases the audit reveals that the home’s biggest problem isn’t the insulation at all, it’s an air leak in the rim joists or attic floor. For MAC-treated homes especially, an audit answers the question of why the energy bill is still high after the sound program’s upgrades. Our Home Energy Audit gives you a written report with the exact priority order for fixes.
Blower Door Test
Signs you need it
High heating bills you can’t explain, drafts you can feel but can’t locate, or a home that’s never been tested.
What it costs in Bloomington
A blower door test in Bloomington runs $200-$400 as part of a full audit.
How we do it
We mount a calibrated fan in an exterior door, depressurize the house, and measure the exact air leakage rate.
Thermal Imaging Inspection
Signs you need it
Cold spots on walls or ceilings, uneven room temperatures, or an attic you suspect isn’t insulated evenly.
What it costs in Bloomington
A thermal imaging inspection in Bloomington runs $150-$300 when added to an energy audit.
How we do it
We scan the interior with a thermal camera to find missing insulation, air leaks, and thermal bridges you can’t see otherwise.
What Home Energy Audit Costs in Bloomington
| Item | Typical range in Bloomington |
|---|---|
| Blower door test | $200-$400 |
| Thermal imaging inspection | $150-$300 |
| Insulation inspection | $100-$250 |
| Full home energy audit | $300-$600 |
Is a home energy audit worth it before insulating in Bloomington?
Yes. Without it, you’re guessing at where your heat is going. The audit tells us the exact leak locations and the right insulation sequence. It usually pays for itself in targeted fixes.
What does a Bloomington energy audit actually show?
It shows the home’s air leakage rate, where the leaks are, the existing insulation levels, and thermal images of missing or settled insulation. You get a written report with priorities. Call (866) 751-4428 to schedule one.

What Bloomington Customers Say
"Walt came out himself, stuck his head in the attic, and told me I had about four inches where I needed fourteen. No sales pitch, just the number and what it would cost to fix it. Crew was here two days later."
- Carl Meadows"We had the walls of our old house filled with foam through small holes from the outside. Patched and painted the same afternoon. The bedrooms hold heat now and the furnace runs a lot less."
- Linda Baumgartner"Good honest work on the attic. The price was a little higher than one online quote, but Walt is the one who actually showed up and the one whose name is on the truck, and that was worth it to us."
- Helen Tran
