Attic Insulation in Bloomington - Same-Day Service, Done Right the First Time

Insulation in Bloomington, MN

Crawl space encapsulation and vapor barrier work in Bloomington usually runs $3,800-$8,500 depending on square footage, moisture damage, and whether the space needs a full cleanout first. Most homes here were built between 1955 and 1975, which means vented crawl spaces with thin plastic or bare dirt floors sitting under ramblers and split-levels that leak heat all winter.

Why Bloomington Homes Are Different

Bloomington’s housing stock is almost entirely a product of one building generation: 1960s and 70s ramblers, bi-levels, and split-levels thrown up fast along the Penn Avenue corridor, the Old Shakopee Road neighborhoods, and the east side subdivisions. Those homes were framed and insulated to standards that made sense in 1965. R-11 walls, a few inches of fiberglass in the attic, and rim joists left completely bare. Now Minnesota code calls for R-49 to R-60 in attics and the math doesn’t work in the old assembly anymore.

The climate makes the gap worse. Bloomington sits on the flat Minnesota River plain with ASHRAE design temperatures around -16°F and over 8,000 heating degree days a year. There’s no topographic windbreak, so Arctic air sweeps straight across the city and finds every unsealed penetration in the building envelope. The result is chronic ice dams on the south-facing roof slopes, frozen pipes in cantilevered bump-outs over garages, and heating bills that run a third higher than they should. Homes in Eden Prairie or Eagan built a decade later simply didn’t get hit with the same combination of early postwar construction methods and this specific climate severity.

Our Main Bloomington Services

Bloomington homeowners call us most often for two things: attics that need to be brought up to current code, and crawl spaces that have been quietly rotting and leaking heat for fifty years.

Attic Insulation in Bloomington

We’ve written a full page about Attic Insulation in Bloomington because it deserves its own treatment. The short version: most Bloomington attics still hold the original 1960s batts, now compressed and dirty and performing at a fraction of their label. We remove or top up as needed and get the assembly to R-49 or better, air sealing every penetration before we cover it. Most jobs happen in one visit.

Crawl Space Encapsulation & Vapor Barrier in Bloomington

Crawl space encapsulation in Bloomington starts around $3,800 for a smaller footprint and runs up toward $8,500 when the space is large, wet, or filled with old debris. The vented crawl spaces under Bloomington’s 1960s ramblers and split-levels are a direct consequence of that era’s building science: foundation vents were supposed to let moisture escape, but in a climate where the ground is frozen for months, they actually pull humid summer air in and let every bit of heat leak out through the floor. The result is cold floors in January, musty air in July, and rim joists that have been sweating for decades. We handle the whole thing under one contract, from vapor barrier to insulation to dehumidification, so you’re not juggling trades. See our full Crawl Space Encapsulation & Vapor Barrier service details.

Crawl Space Vapor Barrier

Signs you need it

Damp smells rising through the floor, visible condensation on foundation walls, or standing water after spring melt are the classic Bloomington tells. Buckled hardwood above the crawl space is another one we see regularly.

What it costs in Bloomington

A 12-mil vapor barrier installation in Bloomington typically runs $1,800-$3,200 depending on the crawl space footprint and how much prep the floor needs.

How we do it

We clean the floor, seal the foundation vents from inside, and run a reinforced 12-mil liner across the entire dirt surface, lapping it up the walls and securing it with mechanical fasteners. Every seam gets taped and the perimeter is sealed to the sill plate.

Crawl Space Moisture Control

Signs you need it

Floor joists with visible mold staining, rusted duct straps, or a relative humidity reading above 60% in the crawl space are all signs the moisture problem is active, not cosmetic.

What it costs in Bloomington

Adding a self-draining dehumidifier and sealing the rim joists in a Bloomington crawl space typically costs $2,200-$4,000.

How we do it

After the vapor barrier is down, we seal the rim joist bays with closed-cell spray foam or rigid board, then install a properly sized dehumidifier that drains on its own. The goal is a crawl space that stays at 45-55% humidity year-round without you touching anything.

What Crawl Space Encapsulation & Vapor Barrier Costs in Bloomington

Does crawl space encapsulation make the house warmer in winter?

Yes. Sealed and insulated rim joists stop the direct thermal bridge between the frozen outside air and the floor system above. Most Bloomington homeowners feel the difference in the kitchen and living room floors within a day or two. Call (855) 657-3403 for a specific quote on your footprint.

Can you encapsulate a crawl space that has standing water right now?

Usually yes, but we address the water source first, whether that’s grading around the foundation, a sump pump, or a french drain. Installing a barrier over actively pooling water just traps the problem. Estimates are free and we walk you through what we find.

Spray Foam Insulation in Bloomington

Spray foam insulation in Bloomington is the highest-performance fix for the era-specific problems in 1960s and 70s construction, especially rim joists and cantilevered floor bays that were never insulated at all. Closed-cell foam gives you R-6.5 per inch plus an air seal in one pass, which matters when design temperatures hit -16°F and wind sweeps across the river plain. In east Bloomington split-levels, the cantilever sections over attached garages are the single biggest source of cold floor complaints we hear every January, and spray foam is the cleanest way to reach them from below. We work with Spray Foam Insulation systems from proven manufacturers, applied by trained crews who handle the chemistry correctly.

Rim Joist Spray Foam

Signs you need it

Cold floors near exterior walls, frost on the inside face of the rim joist in the basement, or mouse activity around the sill plate are direct signs the rim joist bays are unsealed.

What it costs in Bloomington

Sealing the rim joist bays in a typical Bloomington rambler with closed-cell spray foam runs $1,500-$2,800.

How we do it

We mask off the work area, clean the foundation wall, and apply two inches of closed-cell foam across each bay, from subfloor to sill plate. The foam bonds to the concrete and framing, creating an air seal and insulation layer in one step.

Garage Ceiling Spray Foam

Signs you need it

A bedroom or bonus room above the garage that’s always 8-10 degrees colder than the rest of the house, or a garage ceiling that’s warm to the touch while snow still sits on the roof.

What it costs in Bloomington

A garage ceiling spray foam job in Bloomington typically costs $1,200-$2,500 depending on bay count and access.

How we do it

We spray closed-cell foam directly against the underside of the garage ceiling joists after removing any loose fiberglass. This stops the stack effect that pulls cold garage air into the living space above and quiets the room at the same time.

What Spray Foam Insulation Costs in Bloomington

Is closed-cell spray foam worth the extra cost over open-cell in Bloomington?

For rim joists, cantilevers, and any area exposed to ground moisture, yes. Closed-cell gives you a vapor barrier and structural rigidity in addition to higher R-value per inch. Open-cell is fine for interior wall cavities and attic roofs where moisture isn’t a concern. We’ll spec it honestly based on where it’s going.

Can you spray foam an attic that already has fiberglass batts?

We remove the old fiberglass first if you’re converting to a spray foam roof deck, because layering foam over batts creates a moisture trap at the sheathing. In some cases we can leave existing insulation in place and spray only the air-sealing layer at framing junctions. Call (855) 657-3403 and we’ll tell you what your attic actually needs.

Blown-In Insulation in Bloomington

Blown-in insulation in Bloomington is the most cost-effective way to bring a 1960s or 70s attic from R-11 up to R-49 or better in a single visit. The original fiberglass batts in most of these homes have settled, compacted, and lost a meaningful share of their rated R-value over five decades, and topping them off with a thick blanket of blown material is fast, clean, and dramatically effective. On the open river plain with no windbreak, the difference between R-11 and R-49 is the difference between an attic that works and one that feeds ice dams along the eaves every February. We use Blown-In Insulation products from GreenFiber and Johns Manville, chosen for consistent density and settled performance.

Blown-In Cellulose

Signs you need it

Attic insulation that’s below the tops of the ceiling joists, ice dams forming along the eaves, or snow that melts in odd patterns on the roof while the rest of the neighborhood stays covered.

What it costs in Bloomington

Blowing R-49 cellulose over an existing attic in a typical Bloomington rambler runs $1,800-$3,000.

How we do it

We air seal the attic floor penetrations first, then blow cellulose to the full target depth across the entire attic, including the hard-to-reach edges over exterior walls. The material is treated for fire resistance and pest deterrence.

Dense-Pack Wall Insulation

Signs you need it

Exterior walls that feel cold to the touch in winter, rooms over the garage that won’t hold temperature, or high heating bills in a home where the attic has already been upgraded.

What it costs in Bloomington

Dense-packing the walls of an average Bloomington rambler typically costs $4,000-$7,500 depending on access and the number of exterior stud cavities.

How we do it

We drill access holes through the exterior sheathing or interior drywall, then pack each stud cavity with cellulose at a controlled density that prevents settling. The holes are patched and finished so you’d never know we were there.

What Blown-In Insulation Costs in Bloomington

Is blown-in cellulose better than fiberglass for a 1960s Bloomington attic?

Cellulose settles into a more continuous thermal blanket and does a better job of stopping air movement through the insulation itself. Fiberglass blown-in is lighter and can be a good choice for larger attics where rafter clearance is an issue. We’ll recommend one based on your attic’s layout and existing material. Call (855) 657-3403 for an honest spec.

Can you blow insulation over existing fiberglass batts?

Yes, in most cases that’s exactly what we do. We check for moisture stains and rodent damage first, and we remove any batts that are clearly compromised. Then we air seal and blow the new material to a uniform depth across the whole attic.

Radiant Barrier Installation in Bloomington

Radiant barrier installation in Bloomington works best in attics that already have adequate insulation but bake in the summer sun. The flat, exposed roof decks on east Bloomington ramblers collect heat all afternoon, and that heat radiates straight down through the insulation and into the living space even after the sun goes down. A radiant barrier stapled to the underside of the rafters reflects a large share of that radiant load back up, cutting the attic temperature by 20 to 30 degrees on the hottest days. It’s a targeted complement to insulation, not a replacement for it, and in Bloomington’s climate it’s most useful July through September. See the full details on our Radiant Barrier Installation page.

Attic Radiant Barrier

Signs you need it

Second-floor rooms that get noticeably hotter than the main floor in summer, an attic that’s uncomfortably hot in July, or an air conditioner that runs nonstop from noon to midnight.

What it costs in Bloomington

A full attic radiant barrier in a typical Bloomington rambler costs $1,400-$2,200.

How we do it

We staple a reinforced foil barrier across the underside of the roof rafters, leaving a small air gap at the top and bottom for ventilation. The installation covers the entire roof deck area and takes most of a day.

Radiant Barrier & Ventilation

Signs you need it

Attic temperatures above 130°F in summer, warm air pushing down into the house in the evening, or soffit vents that are undersized for the roof’s square footage.

What it costs in Bloomington

Adding a solar attic fan or upgrading existing ventilation alongside a radiant barrier in Bloomington typically runs $600-$1,300.

How we do it

We assess the existing intake and exhaust venting, correct any shortages, and install the barrier so it works with the airflow rather than against it. The goal is a radiant heat reduction plus a properly balanced ventilation cycle.

What Radiant Barrier Installation Costs in Bloomington

Does a radiant barrier help with winter heating bills in Bloomington?

The honest answer is: only slightly. Radiant barriers primarily address summer heat gain. In winter, the insulation on your attic floor is doing the heavy lifting. If your heating bills are high, air sealing and blown-in insulation will pay back far more than a radiant barrier will. We’ll tell you straight if a radiant barrier is the wrong fix for what you’re trying to solve.

Will a radiant barrier make my roof shingles hotter and shorten their life?

Independent testing has shown shingle temperature increases of only a few degrees when a radiant barrier is installed on the underside of the rafters, provided the attic is properly ventilated. That’s within normal variation. We install with ventilation in mind from the start.

Insulation Removal & Replacement in Bloomington

Insulation removal and replacement in Bloomington is the right move when the original 1960s material has been contaminated by rodents, soaked by ice dam leaks, or simply compressed into uselessness. Many of the ramblers and split-levels along the Penn Avenue corridor have never had their attic insulation touched. After fifty-plus years, what’s up there is often a compacted, dusty layer of fiberglass with mouse tunnels running through it. We vacuum it out, sanitize the deck, air seal, and blow in fresh material to current code. The entire process usually happens in one visit. Full details on our Insulation Removal & Replacement page.

Attic Insulation Removal

Signs you need it

Insulation that’s stained, matted, or smells of animal activity, or insulation that’s been compressed to half its original depth by years of foot traffic and storage.

What it costs in Bloomington

Removing old attic insulation from a typical Bloomington rambler costs $1,500-$2,800, depending on depth and contamination.

How we do it

We run a high-powered vacuum from the attic to a sealed container on the truck, removing the old material without letting dust into your living space. The attic is left clean and ready for inspection.

Contaminated Insulation Removal

Signs you need it

Droppings visible on the insulation surface, batts that crumble when touched, or a persistent musty odor that gets worse in humid weather.

What it costs in Bloomington

Removing rodent-contaminated insulation from a Bloomington attic runs $2,000-$3,500, including full sanitizing of the deck and framing.

How we do it

We remove every last bit of contaminated material, mist the entire attic with an antimicrobial sanitizer, and leave the space ready for fresh insulation. We don’t just scrape the surface, the contaminants have to go too.

What Insulation Removal & Replacement Costs in Bloomington

Is it cheaper to just blow over the old insulation instead of removing it?

Sometimes, yes, and we’ll recommend that when the existing material is clean and intact. If it’s contaminated or compressed, blowing over it just seals the problem under a fresh layer. The only way to know is to get up there and look. Call (855) 657-3403 for a free attic assessment.

How long does insulation removal take?

Most Bloomington attics are fully removed in four to six hours, and replacement happens the same day or the following morning. We schedule the whole job as one clean sequence so you’re not living with an exposed attic.

Attic Air Sealing in Bloomington

Attic air sealing in Bloomington is the step most contractors skip, and it’s the step that matters most in this climate. Every gap around a can light, a plumbing vent, or a wiring penetration is a direct chimney pulling warm air out of the house and drawing cold air in through the rim joist. In a 1960s Bloomington rambler, the combined effect of dozens of small leaks can equal leaving a window open all winter. Sealing them before adding insulation is the only way to get the full rated performance from whatever insulation you install. We treat it as a mandatory first step on every attic job. Our full process is on the Attic Air Sealing page.

Attic Floor Air Sealing

Signs you need it

Dust streaks on the fiberglass batts around penetrations, drafts felt around ceiling fixtures, or high heating bills despite adequate visible insulation.

What it costs in Bloomington

Air sealing a typical Bloomington attic floor runs $1,200-$2,000, not including any insulation that follows.

How we do it

We move the existing insulation aside, seal every penetration with foam or caulk as appropriate, and then reset or top up the insulation. The sealing work comes first, always.

Top Plate & Penetration Sealing

Signs you need it

Ice dams forming on specific roof sections, comfort differences between rooms on the same floor, or plumbing stacks that frost up inside the attic in January.

What it costs in Bloomington

Sealing the top plates and all mechanical penetrations in a Bloomington attic typically runs $800-$1,500.

How we do it

We seal the junction between the drywall and the top plate along every exterior wall, then seal all plumbing vents, electrical drops, and exhaust fan boxes using fire-rated foam or caulk. Each penetration gets treated individually.

What Attic Air Sealing Costs in Bloomington

Why can’t I just add more insulation without air sealing?

Insulation slows heat transfer through materials, but it doesn’t stop air movement. Warm air will keep leaking out through the same gaps, carrying moisture with it. In Bloomington, that moisture freezes on the sheathing and becomes ice dam fuel. Air sealing always comes first, and the difference in comfort is immediate.

Does air sealing make the house too tight and stale?

Not in a 1960s home. Even after aggressive air sealing, a house of this era still has plenty of natural air exchange. For homes that get very tight, we recommend a mechanical ventilation strategy, but that’s rare in this housing stock.

Wall Insulation in Bloomington

Wall insulation in Bloomington addresses the fact that most 1960s and 70s ramblers and split-levels were built with R-11 fiberglass batts in the wall cavities. Fifty years later, those batts have settled, compressed, and left gaps at the top of every stud bay. Rooms over garages, exterior bedrooms, and any wall facing the open river plain get noticeably cold in winter and hot in summer. Dense-packing or injection foam into those cavities is a one-day fix that transforms comfort without tearing out drywall. We’ve written the full process on the Wall Insulation page, and the materials we use come from Owens Corning and Knauf.

Injection Foam Wall Insulation

Signs you need it

Exterior walls that are cold to the touch in winter, rooms that won’t hold heat even with the furnace running, or wide temperature swings between adjacent rooms.

What it costs in Bloomington

Injection foam wall insulation for a typical Bloomington rambler runs $4,500-$8,000 depending on wall area and accessibility.

How we do it

We drill small access holes through the exterior siding or interior drywall and inject expanding foam into each stud cavity. The foam fills the gaps the original batts left behind and air seals as it insulates.

Drill & Fill Wall Insulation

Signs you need it

Homes where the walls have no insulation at all, or where the original batts were installed poorly and left voids around outlets and windows.

What it costs in Bloomington

Drill and fill with dense-pack cellulose in a Bloomington home typically costs $4,000-$7,500.

How we do it

We drill one to two small holes per stud bay, blow cellulose in at a density that prevents settling, and patch the holes to match. Your walls stay intact, and the job’s done in a day.

What Wall Insulation Costs in Bloomington

Will drill and fill damage my siding or drywall?

The holes are small, typically 1 to 2 inches, and we patch and finish them so they’re invisible. On stucco or brick we work through the interior instead, patching the drywall and leaving it ready for paint. Most homeowners can’t find the holes after we’re done.

Can you insulate just one cold room instead of the whole house?

Yes, and it’s a common request for Bloomington split-levels where one room hangs over the garage or sits over a cantilever. We’ll isolate the problem area, insulate what’s accessible, and give you a price for doing just that section. Call (855) 657-3403 and we’ll walk the room with you.

Attic Cleaning & Rodent Proofing in Bloomington

Attic cleaning and rodent proofing in Bloomington goes hand-in-hand with insulation because rodents love the loose fiberglass in 1960s attics. Mice and squirrels tunnel through old batts, leaving trails of droppings and urine that contaminate the insulation and degrade the air quality in the house. Once the pests are out, we seal every entry point along the soffits, gable vents, and roof intersections, then sanitize and re-insulate. This isn’t a pest control add-on; it’s the difference between fixing the problem and just changing the bedding. Full details live on the Attic Cleaning & Rodent Proofing page.

Attic Cleanout

Signs you need it

Visible droppings, chewed wiring, or insulation that’s been tunneled through and flattened in paths. Squirrel nests in the eaves are another sign the attic has been claimed.

What it costs in Bloomington

An attic cleanout with removal of contaminated insulation in a Bloomington home runs $1,800-$3,200.

How we do it

We remove every bit of old insulation and debris, vacuum the deck, and leave the space clean enough to inspect. You see what we see before any new material goes in.

Rodent Proofing & Exclusion

Signs you need it

Scratching sounds in the evening, droppings in one corner of the attic, or daylight visible through gaps at the soffit and roofline from inside.

What it costs in Bloomington

Sealing the typical entry points on a Bloomington rambler costs $600-$1,400, depending on how many gaps need closing.

How we do it

We seal every gap a rodent could squeeze through, using steel mesh, foam, and flashing at the vulnerable intersections. The goal is an attic that stays sealed for good, not just until the next squirrel finds the same hole.

What Attic Cleaning & Rodent Proofing Costs in Bloomington

Do you handle the trapping or do I need a separate pest control company?

We focus on exclusion and restoration. If you have active rodents, we’ll recommend a licensed pest control partner to handle trapping, and we’ll come in behind them to seal the entries and clean the damage. The sealing part is ours, and it’s what prevents the next infestation. Call (855) 657-3403 and we’ll walk you through the sequence.

How soon after rodent proofing can you re-insulate?

Immediately. Once the attic is cleaned, sanitized, and sealed, we blow in new insulation the same day. The new material is pest-resistant, and the sealed envelope means it stays clean.

Home Energy Audit in Bloomington

A home energy audit in Bloomington is the diagnostic starting point that makes every other insulation and air sealing service smarter. Many Bloomington homeowners can feel that something’s wrong, the cold floor or the ice dam or the high bill, but they don’t know which problem is actually driving it. A blower door test pressurizes the whole house and lets us measure the total leakage, while a thermal imaging camera shows us where that leakage is happening and where the insulation has failed. From there, we can target the fix instead of guessing. That’s the Home Energy Audit process in full.

Blower Door Test

Signs you need it

High energy bills without an obvious cause, drafts that you can’t localize, or a house that’s been partially upgraded but still doesn’t perform.

What it costs in Bloomington

A blower door test as part of a full audit in Bloomington runs $300-$500.

How we do it

We mount a calibrated fan in an exterior door frame, depressurize the house to a standard pressure, and measure the airflow. The number tells us exactly how leaky the envelope is, in cubic feet per minute, not vibes.

Thermal Imaging Inspection

Signs you need it

Uneven wall or ceiling temperatures that you can feel but can’t explain, or suspected moisture in wall cavities where no leak is visible.

What it costs in Bloomington

A thermal imaging scan of a Bloomington home’s exterior walls and ceilings runs $200-$400.

How we do it

We walk the house with a thermal camera that reads surface temperatures, revealing missing insulation, air leaks, and moisture that the eye can’t see. The images become the map for whatever work follows.

What Home Energy Audit Costs in Bloomington

Will an energy audit tell me which upgrades are worth the money?

Yes. The audit gives you a ranked list of problems by impact: where the air is leaking, where the insulation has failed, and which fixes will pay back fastest in a Bloomington climate. You’ll have real data, not a sales pitch. Call (855) 657-3403 to schedule one.

Do I need an audit before every insulation upgrade?

Not every time, but if your home has multiple symptoms, cold floors, ice dams, a damp crawl space, the audit saves money by showing which problem is the root cause. We can quote specific work without one, but the audit makes the work targeted.

Brands We Service in Bloomington

FAQs About Insulation in Bloomington, MN

How quickly can you schedule an insulation job?

Scheduling depends on current demand and the scope of the work. After a quick phone call or an on-site look at the attic, crawl space, or walls involved, we set a start date for the Bloomington job and let you know how long it will take before any work begins.

Do I need a permit for insulation work?

Routine insulation work typically doesn’t require a permit. Minnesota code now calls for R-49 to R-60 in attics, well above what most ramblers here received when they were built in the 1960s and 70s, and we size new material to that current standard.

How does the written estimate work?

Before any work starts, we walk the attic, crawl space, or walls being insulated and write up the exact scope and price for the Bloomington job in a single document. That number is fixed before any material is opened or any tear-out begins, so there are no surprise add-ons once work is underway.

Which nearby areas do you also cover?

We also work throughout the surrounding area, including Houston, Spring, The Woodlands, Katy, Pearland, and Humble, and Bloomington appointments are scheduled alongside jobs in those communities. If your home falls just outside this list, call and we’ll confirm whether we can reach you.

What happens to my old insulation when you replace it?

We remove old batts, blown-in material, or vapor barrier and bag or vacuum it out for disposal before any new insulation goes in. If it’s contaminated with rodent droppings, mold, or moisture damage, we handle it separately with sanitizing before the space is sealed and refilled.
