Insulation Company in Bloomington, CA
Bloomington homeowners usually reach out to us about blown in insulation first. It’s the fastest way to fix the core problem in this city’s housing stock: attics that were built with almost nothing between the living space and a roof that soaks up 150°F+ heat for months at a stretch. We’re Birch Insulation, and we’ve worked in Bloomington since 2015, matching blown-in fiberglass, cellulose, and spray foam to homes by their age, framing, and energy bills, not by what happens to be sitting on a warehouse shelf. Call us at (866) 511-7592 for a straight answer about your attic.
Why Bloomington Homes Are Different
Bloomington sits in the Inland Empire’s heat corridor, where summer attic temperatures routinely climb past 150°F and stay there from June into October. The insulation problem here isn’t freezing pipes or winter drafts – it’s radiant heat loading that turns an under-insulated attic into an oven radiating down into bedrooms and hallways all afternoon and evening. Most of Bloomington’s housing stock is single-story ranch and tract construction from the 1950s through the 1980s, built long before modern Title 24 insulation requirements existed. These wood-frame homes have low-pitch roofs and attics that were often left with a thin layer of settled fiberglass or nothing at all. When we open an attic in Bloomington, we typically find one of two things: original insulation that has compressed to a fraction of its rated R-value, or bare ceiling joists with no insulation whatsoever. This pattern is consistent across the 92316 ZIP. We also see knee-wall construction along attic boundaries that traps heat and makes venting inadequate. The fix almost always involves a retrofit – adding blown-in material over what exists or starting from scratch – paired with improved ventilation so the attic doesn’t bake moisture into the framing.
Our Main Bloomington Services
Two services account for most of what Bloomington homeowners call Birch Insulation about: attic insulation retrofits and spray foam for hard-to-seal spaces. Both are handled in-house, start to finish.
Attic Insulation in Bloomington
Older Bloomington ranch homes rarely have enough attic insulation by modern standards, and what’s up there has often settled or been disturbed by decades of roof work, wiring, and storage. We assess what’s present, calculate the R-value actually being delivered, and recommend either a top-up of blown-in fiberglass or cellulose, or a full removal and re-insulation when moisture or pest damage has compromised the material. In Bloomington’s heat, getting the attic to R-38 or better is where the cooling bill difference shows up. Read more about Attic Insulation in Bloomington.
Spray Foam Insulation in Bloomington
Some Bloomington homes have attic configurations, additions, or converted spaces where blown-in material can’t reach or venting can’t be added. That’s where closed-cell spray foam earns its place – sealing the roofline itself so the attic becomes conditioned space rather than a heat trap. We carry both Icynene and Demilec spray foam, which means we can choose based on the specific air-sealing depth and budget your roof geometry calls for. Spray Foam Insulation in Bloomington covers the details.

Blown In Insulation in Bloomington
Blown in insulation is the most common fix we install in Bloomington because it matches the housing stock perfectly. Most homes in this city are older tract and ranch builds with low-pitch roofs and attics you can’t easily crawl through – conditions where blown-in fiberglass or cellulose goes in quickly, fills irregular cavities completely, and delivers an immediate jump in ceiling R-value without ripping out drywall. In a climate where the attic hits 150°F through summer, rebuilding that thermal barrier is the single most effective step a Bloomington homeowner can take to cut cooling costs and quiet a house. For more detail on materials and method, see our full Blown In Insulation page.
Cellulose Insulation
Signs you need it
You notice rooms under the attic never cool down on 100°F days, or your cooling bills climb every summer even though the AC unit itself is working properly.
What it costs in Bloomington
Blown-in cellulose attic insulation for a typical Bloomington ranch home runs $1.30 – $2.20 per square foot of attic area.
How we do it
We inspect the attic for venting and air leaks, prep the space, dense-pack or loose-fill GreenFiber cellulose to the target R-value using a calibrated blower, and verify depth and coverage before wrapping up.
Blown In Attic Insulation
Signs you need it
Your attic has bare joists, paper-thin original insulation from the 1960s or 1970s, or areas where material has settled below the top of the ceiling joists.
What it costs in Bloomington
Blown-in attic insulation here typically runs $1.00 – $2.50 per square foot, including prep, material, and labor.
How we do it
We seal recessed light housings and top plates where practical, blow the material to the depth required for R-38 or better, and confirm even coverage with depth markers across the attic floor.
Blown In Cellulose Insulation
Signs you need it
You want higher recycled content and better sound damping than fiberglass offers, or the existing attic material has blown thin and needs a full top-up.
What it costs in Bloomington
Blown-in cellulose in Bloomington runs $1.30 – $2.20 per square foot for a typical attic retrofit, depending on depth and access.
How we do it
We run the GreenFiber cellulose through a blower at controlled density, building depth layer by layer to reach the specified R-value without gaps or over-compaction.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old, matted fiberglass batts that have fallen between joists, or the original material has settled and no longer covers the full ceiling plane.
What it costs in Bloomington
Blown-in fiberglass for a Bloomington attic runs $1.00 – $2.00 per square foot, including removal of any unusable old material where needed.
How we do it
We clear the attic floor, mark target depths, and blow Owens Corning loose-fill fiberglass to a consistent R-value, leaving the material evenly distributed and fluffed rather than compacted.
Loose Fill Insulation
Signs you need it
Your attic has obstructed or uneven framing, low clearance, or odd cavities that batt insulation can’t fill correctly without leaving gaps.
What it costs in Bloomington
Loose fill insulation in Bloomington ranges from $1.00 – $2.50 per square foot depending on material choice and whether we’re topping up or filling an empty attic.
How we do it
We assess the cavity depth and access, blow loose fill into the space at the correct density for the material and R-value, and spot-check depth across the entire area to confirm an even thermal layer.

Is blown in insulation worth it in Bloomington’s heat?
Yes, and the return shows up fast in this climate. An under-insulated attic lets 150°F air radiate into your rooms for hours each summer evening, forcing the AC to run constantly. Rebuilding the thermal layer cuts that heat gain, which is why blown-in retrofit is the highest-payback insulation job for most Bloomington homes. Call (866) 511-7592 to size your attic.
How long does blown in insulation take in a Bloomington home?
Most Bloomington ranch homes are insulated in one day. A typical single-story with a low-pitch roof and standard attic access takes four to six hours from prep to final depth check, with no disruption inside the house. We’ll confirm a time window when we inspect the attic. Call (866) 511-7592 to schedule a walkthrough.

Prices in Bloomington creep upward when an attic needs old material removed first, when access is tight enough to slow the crew down, or when we’re adding venting in the same visit because the original roof design never had enough. We quote a fixed price before any work starts, and that number doesn’t change unless you change the scope.

For standard blown-in attic or wall insulation retrofits, Bloomington homeowners generally do not need a separate permit because the work doesn’t alter structural elements or the building envelope. When insulation is part of a larger remodel or we’re sealing a roofline with spray foam, the project may fall under the building department’s review. We’ll tell you exactly what applies to your job before anything starts.
Yes, and that’s a large share of what we do here. Uninsulated 1950s through 1980s attics are common in Bloomington, and we’re set up for full retrofits: clearing the attic floor, sealing bypasses, adding venting if needed, and blowing insulation to current R-value targets in a single visit.

What Bloomington Customers Say

— Allen Kim"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Katie Whitaker"Spray foam in the rim joists in the basement. The cold floors above them are gone."
