If your summer cooling bills have climbed and certain rooms never seem to hold temperature, call us at (866) 605-6949 for a straight answer and a free estimate.
We know Bloomington’s housing stock because we work in it regularly. The stucco ranches off Cedar Avenue, the converted garages near Valley Boulevard, the older wood-frame homes tucked behind Slover Avenue. These houses were built for a different climate reality than the one Bloomington lives in now. A tighter thermal envelope changes how they perform in July.
Key Takeaways:
- Spray foam in Bloomington costs $2.50 – $6.50 per square foot installed, with most whole-attic jobs landing between $4,500 and $11,000.
- Open-cell foam suits most Bloomington attics; closed-cell is the better call for garage conversions, rim joists, and slab-edge work.
- We carry both Icynene and Demilec spray foam systems, so the recommendation is based on your house, not what’s on our truck.
- Homes built in the 1950s through 1970s in Bloomington almost always need air sealing before or alongside insulation.
Why Hollywood Insulation Co Is Bloomington’s Preferred Spray Foam Insulation Company
We’re a dedicated insulation specialist, not a general contractor who happens to offer insulation on the side. That distinction matters in Bloomington, where the dominant job is diagnosing and correcting under-insulated older homes rather than insulating new construction. Our technicians spend every working day inside attics, rim joists, and garage conversions, and Bloomington’s particular mix of 1950s-to-1970s wood-frame construction, stucco exteriors, and extreme summer attic temperatures is familiar ground.
Bloomington homeowners call us because we carry eight manufacturer brands across every major insulation category, including Icynene and Demilec for spray foam. That portfolio breadth means we recommend the method that actually fits the house. Sometimes that’s open-cell foam in an attic. Sometimes it’s closed-cell on a rim joist. Sometimes the honest answer is that a different material altogether makes more sense for the budget and the building. We’d rather give you the right answer than sell you the most expensive one.
Noel Camacho runs our team with a simple rule: match the method to the home. That means no forcing spray foam where it doesn’t belong, no upselling, and no vague recommendations. It also means we respond quickly to Bloomington. Most estimates happen within a few days of your call, and our crew is familiar with the streets, the setbacks, and the building patterns here.
Crawl Space Spray Foam Insulation in Bloomington
Crawl Space Spray Foam Insulation in Bloomington addresses a problem most homeowners in the 92316 ZIP never see: the uninsulated floor cavity under older homes that lets hot air rise into living spaces all summer. In Bloomington’s semi-arid climate, where daytime highs routinely cross 100°F, a vented crawl space turns into a heat sink that keeps your floors warm and your air conditioner running longer than it should. Spraying closed-cell foam against the crawl space walls, or applying open-cell foam to the subfloor, breaks that heat path.
The cost for a typical Bloomington crawl space runs $3,000 to $7,000 depending on square footage and access. Tight access, low clearances, and existing moisture issues can push that higher, which is why we quote after looking at the space, not before.
A Heat Break Under Older Floor Systems
Most Bloomington homes from the 1950s and 1960s sit over vented crawl spaces. Those vents were considered a feature when the houses were built. In modern practice, they’re a liability. Closed-cell foam on the foundation walls seals out exterior heat, while open-cell foam under the subfloor quiets footfall and stops the chimney effect that pulls hot air upward.
Moisture and Vapor Control
Bloomington’s low humidity works in your favor, but occasional Santa Ana winds and winter rains still introduce moisture under the house. Closed-cell spray foam acts as a vapor barrier at 2 inches of depth, which protects floor joists and keeps the space drier. For homes where standing water appears after heavy rain, we address drainage first. Foam over standing water doesn’t fix anything.
Garage Spray Foam Insulation in Bloomington
Garage Spray Foam Insulation in Bloomington usually means one of two scenarios: an attached garage that turns into a furnace from June through September, or a garage that was converted to living space decades ago and never properly insulated. The second scenario is common in Bloomington, where garage conversions were a popular way to add bedrooms or rental units to older homes. Many of those conversions have no insulation in the walls, nothing along the slab edge, and original single-pane windows. That’s why the room never feels comfortable no matter what the thermostat says.
Spraying closed-cell foam to the garage ceiling and walls typically runs $2,800 to $6,500 in Bloomington, depending on the size and whether we’re also sealing the slab edge and the garage door opening. A full garage conversion retrofit with attention to all thermal bridges costs more.
The Converted Garage Problem
Because many Bloomington homes were built between the 1950s and 1970s with attached garages that were later converted to living space, spray foam in these garages must address both the thermal envelope and the original uninsulated slab edge to prevent heat gain from the ground. If you only insulate the ceiling and walls but leave the slab edge exposed, the concrete keeps absorbing ground heat and radiating it into the room. We treat the slab edge as part of the job, not an afterthought.
Ceilings, Walls, and the Door Opening
A garage ceiling that shares a wall with living space needs insulation on both sides, and the garage door itself is a giant uninsulated panel absorbing sun all afternoon. Spray foam on the interior side of the door can help, but an insulated door replacement often makes more sense for east- and south-facing exposures. We’ll tell you what’s worth doing and what isn’t.
Trusted Brands We Service in Bloomington
We install both Icynene and Demilec spray foam systems, two of the most specified spray polyurethane foam brands in North America. Icynene open-cell foam is our default recommendation for Bloomington attics where air sealing and R-value matter most. Demilec closed-cell foam is the stronger choice for rim joists, crawl space walls, and garage conversions where you need moisture control and structural rigidity in the same pass. We also carry Rockwool mineral wool and CertainTeed products for homes where a hybrid approach makes sense. Parts and materials are stocked locally, which keeps Bloomington jobs moving without waiting on shipments from out of state.
Common Spray Foam Insulation Problems We See in Bloomington Homes
- Foam sprayed over settled blown-in insulation: Many Bloomington attics have old fiberglass or cellulose that has compressed to a fraction of its original depth. Spraying foam directly over that layer traps heat and causes the foam to detach from the roof deck within a few years. The old material has to come out first.
- Garage conversions with missing slab-edge insulation: The ceiling gets sprayed, the walls get sprayed, but the slab edge stays exposed. Ground heat migrates through the concrete and into the room, undoing much of the work. This is the single most common oversight we correct in Bloomington.
- Cracking and shrinkage around old window frames: 150°F attic temperatures and Santa Ana wind cycles cause thermal expansion and contraction that low-density foam doesn’t always survive if applied without proper substrate preparation. We prep the framing and choose the right foam density for the location.
- Unsealed top plates and penetrations: In 1960s-era Bloomington homes, the gaps around wiring, plumbing vents, and top plates leak air even after insulation is added. Spray foam is an air sealing material first and an insulator second. If the sealing step is skipped, the R-value doesn’t matter much.
Pricing for Spray Foam Insulation in Bloomington, CA
Spray foam insulation in Bloomington runs $2.50 to $6.50 per square foot installed. Open-cell foam sits at the lower end of that range, typically $2.50 to $4.00 per square foot. Closed-cell foam runs higher, usually $4.50 to $6.50 per square foot, because it delivers roughly double the R-value per inch and serves as a vapor barrier. A standard 1,200-square-foot attic in a Bloomington ranch house lands around $4,500 to $6,500 for open-cell. A smaller rim joist job might be $1,200 to $2,500. Garage conversions run $2,800 to $6,500 depending on scope. The biggest cost variables are access, existing insulation removal, and whether slab-edge work is included.

FAQs About Spray Foam Insulation in Bloomington
No. The existing blown-in fiberglass or cellulose must be removed first, because spraying foam over a settled layer traps heat at the roof deck and causes the foam to lose adhesion. We remove the old material, seal the top plates and penetrations, then apply foam directly to the roof deck or attic floor. Call (866) 605-6949 and we’ll assess what’s currently in your attic.
Spray foam creates an air seal that stops superheated attic air from pressing down into your living space through gaps around wiring, light fixtures, and top plates. In Bloomington, where attic temperatures routinely exceed 150°F, that seal matters more than the R-value alone. It also slows radiant heat transfer through the roof deck, which is the primary driver of cooling costs here.
Yes, but only if the slab edge, walls, and ceiling are all addressed. Many Bloomington conversions have no insulation at the slab edge, so ground heat keeps radiating into the room even after the walls are sprayed. We treat the conversion as a complete thermal envelope, not a single-surface fix. Most converted garage retrofits in Bloomington run $2,800 to $6,500.
Open-cell Icynene foam is the right choice for most Bloomington attic and wall cavities because it expands to fill irregular framing and allows moisture to pass through rather than trapping it. Closed-cell Demilec foam is better for rim joists, crawl space walls, and slab-edge work where you need a vapor barrier and higher R-value per inch. We recommend based on the specific location in your house.
It depends on the door’s condition. An old uninsulated door facing west or south will absorb enough heat to undo much of what the foam accomplishes. If the door is structurally sound, we can spray the interior panels. If it’s warped, rusted, or failing, replacing it with an insulated door before we foam the ceiling and walls is the smarter sequence. Call us and we’ll look at it together.
Call Hollywood Insulation Co for Spray Foam in Bloomington
We’ve sprayed attics, rim joists, and garage conversions across Bloomington long enough to know which homes leak air and heat the most. We recently sprayed Icynene in the attic of a 1962 stucco ranch on Locust Street where decades of blown-in fiberglass had settled to less than 4 inches and attic temps routinely hit 150°F. Our crew removed the old insulation, sealed all top plates and penetrations, and applied 6 inches of spray foam to the roof deck, dropping the attic temperature by 30°F and cutting the homeowner’s summer cooling bill by roughly 25%.
That’s the kind of result we aim for on every Bloomington job. If your home runs hot in the summer, cold in the winter, or has a converted garage that never feels right, call (866) 605-6949 for a free, honest estimate. We’ll tell you what’s worth doing, what isn’t, and what the right material is for your house.
