Why Fontana Insulation Is Bloomington’s Preferred Spray Foam Company
Noel Arredondo built Fontana Insulation around a simple idea: carry every major insulation material, then recommend the one that fits the house. That matters in Bloomington because the city’s housing isn’t uniform. A 1950s stucco ranch near Cedar Avenue has different cavity depths and venting than a newer home south of Jurupa Avenue. We’ve worked enough attics in 92316 to know what we’re likely to find before the ladder even goes up.
Being material-agnostic means we don’t have to sell spray foam when something else would work better. But when spray foam is the right call, we install the two brands we trust most: Icynene and Demilec, both authorized lines. Eight total brands across fiberglass, mineral wool, spray foam, and cellulose means the recommendation comes from the attic’s condition, not our inventory.
Spray Foam Insulation Contractors in Bloomington
Spray foam insulation contractors in Bloomington handle two distinct foam types: open-cell for interior sound control and air sealing, and closed-cell for higher R-value per inch plus moisture resistance. The job starts with removing or bridging whatever failed insulation already exists, then applying foam in controlled lifts to the roof deck, gable walls, or rim joists. A typical Bloomington attic application runs $2,200 to $4,600 for closed-cell and $1,800 to $3,400 for open-cell.
Open-Cell for Interior Comfort
Open-cell foam expands to fill irregular cavities, which matters in Bloomington’s older homes where framing dimensions were never perfectly square. It air-seals well and cuts noise from the 10 freeway or rail lines that run through the city. R-value runs around R-3.5 per inch.
Closed-Cell for Thermal Block
Closed-cell packs roughly R-6.5 to R-7 per inch and adds structural rigidity. In Bloomington’s shallow attics, that higher R-value per inch is often the deciding factor, since there isn’t much depth to work with before running out of space.
Our Spray Foam Insulation team handles everything from rim joist sealing to full attic encapsulation, all in-house. No subcontracted crews.
Spray Foam Attic Insulation in Bloomington
Spray foam attic insulation in Bloomington usually means converting a vented, 140-degree attic into a sealed, conditioned space that stays within ten degrees of the living area. We apply foam to the roofline rather than the ceiling, which moves the thermal boundary to where the heat actually enters. Bloomington attic spray foam jobs typically run $2,400 to $4,600.
The Real Problem is Radiant Heat
Bloomington gets hammered by direct sun on mostly unshaded lots. A low-pitch roof on an old Route 66 tract home absorbs solar energy all afternoon, and that heat radiates down into the living space even after the sun sets. Spray foam without addressing the radiant path helps, but pairing foam with a radiant barrier is what actually stops the heat transfer.
Prep Work on Sun-Baked Batts
We rarely find clean, empty attics in Bloomington. Most have original kraft-faced fiberglass that’s been baking for 50 or 60 years. That material has to come out, and the top plates and penetrations need air-sealing, before foam goes in. Skipping that prep is how you get delamination and wasted material.
Trusted Brands We Service in Bloomington
We carry Icynene and Demilec for spray foam because both have decades of field performance data in hot climates. Johns Manville and CertainTeed round out our fiberglass options for homes where foam isn’t the right fit, and Rockwool gets specified when fire resistance matters as much as thermal performance. Bloomington customers get access to all of these through one contractor, which means one crew, one warranty path, and one phone number when questions come up.
Common Spray Foam Insulation Problems We See in Bloomington Homes
- Sun-degraded kraft-faced batts. Original 1950s to 1970s fiberglass batts in shallow Route 66 attics get baked flat and compressed. The kraft facing cracks, the fiberglass slumps, and you’re left with unsealed air channels. Foam applied over this without removal will delaminate within a few seasons.
- Off-ratio spray foam from hot-weather application. When attic temps exceed 140°F, improperly calibrated foam can shrink and crack. We monitor substrate temperature and foam ratio on every Bloomington job, because a foam install done wrong in July fails by September.
- Under-applied foam on low-pitch roofs. A thin coat of closed-cell on an unshaded low-pitch roof won’t stop the radiant bake. The attic still heats up, cooling bills stay high, and the homeowner thinks spray foam doesn’t work. It’s not the material, it’s the application depth.
- Rim joist gaps in older slab foundations. Many Bloomington homes sit on slabs with unsealed rim joists that let 100+ degree exterior air pour into the floor cavity. This is a fast, high-impact fix when paired with attic work.
Pricing for Spray Foam Insulation in Bloomington, CA
For a typical 1,200-square-foot single-story home in 92316, open-cell attic foam runs $1,800 to $3,400 and closed-cell runs $2,200 to $4,600. Rim joist sealing alone is usually $600 to $1,200. Garage ceiling spray foam runs $900 to $2,100 depending on square footage. What moves the price: attic accessibility, how much failed insulation needs removal, whether we’re adding a radiant barrier, and the foam thickness your roofline requires.

FAQs About Spray Foam Insulation in Bloomington
Yes, spray foam helps with Bloomington’s summer heat, but only if it’s applied to the roofline and paired with good air sealing. The heat that makes your air conditioner run constantly comes from the attic, where temperatures climb past 140°F. Sealing that space with foam moves the thermal boundary and keeps the heat from radiating into your living areas. Call (866) 271-1602 for an assessment of your specific attic.
No, spray foam should not go over degraded kraft-faced batts. The paper facing breaks down after decades of Bloomington heat, and foam applied over it will eventually delaminate and fall away. We remove the old material, air-seal the top plates and penetrations, then apply foam to a clean substrate. It adds labor, but it’s the difference between a foam job that lasts twenty years and one that fails in three.
Spray foam holds up better than fibrous insulation in Bloomington’s heat because it doesn’t slump, compress, or lose R-value from moisture the way fiberglass and cellulose can. Closed-cell foam also acts as an air barrier, which fiberglass never does. The dry climate actually helps: foam doesn’t face the moisture challenges here that it would in coastal areas. The main requirement is proper application during hot weather, which is why we monitor conditions closely on summer installs.
Closed-cell spray foam gives you roughly R-6.5 to R-7 per inch and blocks moisture, which is why we recommend it for Bloomington roof decks where space is tight and radiant load is high. Open-cell gives you R-3.5 per inch and costs less, but you need more inches to hit the same performance. In shallow mid-century Bloomington attics, closed-cell usually wins because you simply don’t have the depth for thick open-cell lifts.
Spray foam insulation should last the life of the home in Bloomington when installed correctly, meaning a clean substrate, proper temperature conditions, and correct application thickness. Closed-cell foam doesn’t settle or degrade the way fiberglass does, and Bloomington’s dry climate means moisture-related breakdown is rare. We stand behind the installs we do in 92316, and call (866) 271-1602 if you want to discuss warranty details for your specific project.
One More Thing About Bloomington Attics
On a 1950s stucco ranch near Old Route 66 in 92316, our crew found original kraft-faced batts baked flat and falling apart, with attic temps hitting 140°F. We removed the failed batts, air-sealed the top plates and penetrations, then applied Icynene spray foam to the roof deck and gable walls, cutting attic heat gain and stopping the radiant bake that was driving cooling bills. That’s the real job in this city, and it’s not something a generic insulation crew handles well. The shallow attics, the unshaded low-pitch roofs, the sun-degraded batts, they’re all part of the same problem. Spray foam is the answer when it’s applied with an understanding of what Bloomington’s climate actually does to a house.
