Bloomington’s older housing stock wasn’t built for 100°F summers. Many of these homes had no insulation at all when they went up, and the ones that did got sawdust or newspaper, which has long since settled into something closer to cardboard. That’s why we look at every Bloomington job as a retrofit, not a quick top-off. The house tells us what it needs, and we write the exact price down before a single hose comes off the truck.

- Every job gets the Kingswell Guarantee: written price first, committed arrival window, clean job site, written guarantee, and a free return visit if the work fails within 365 days
- We work with eight brands including Demilec and Owens Corning, so the foam recommendation fits your house, not our truck
Why Woolsey Insulation Riverside Is Bloomington’s Preferred Spray Foam Insulation Company
Bloomington homeowners tend to be wary of insulation contractors, and for good reason. This is an unincorporated pocket of San Bernardino County where building codes changed over the decades and a lot of work got done without permits. Homeowners here have seen the aftermath: half-finished attics, insulation blown into soffit vents, prices that changed at the front door. We don’t play that game. Our Spray Foam Insulation team writes the price before any work begins, every single time, no exceptions.
What Bloomington customers tell us they value most is the live phone. Our phones are answered by a real person 24 hours a day, 7 days a week. If you call at 6 a.m. on a Sunday because your attic is radiating heat through the ceiling, you get a person, not a menu. Glenn Hartley leads the Woolsey team, and he’s built the operation around one idea: a written guarantee on every job, not a handshake. If the work isn’t right within 365 days, we come back and fix it. In writing. At no charge.
Background-checked, uniformed technicians show up in the committed arrival window. You know exactly who’s walking into your house, and you know the price before they touch anything. That combination of honesty and accountability is rare in this trade, and it’s why so many Bloomington calls to us start with “a neighbor told me you actually answer your phone.”
Spray Foam Insulation Contractors in Bloomington
Spray foam insulation contractors in Bloomington deal with a housing stock that most other Southern California cities have already torn down and rebuilt. These are 1950s and 1960s ranch homes, many built on the old dairy parcels west of Cedar Avenue, with wall cavities that were never designed for modern insulation. When we foam these homes, we’re not doing a standard install. We’re adapting to whatever the last 60 years left us.
A typical spray foam retrofit in Bloomington starts with a full attic inspection to find what’s already up there. In pre-code homes, that often means compacted sawdust or newspaper fill that has to be removed before new foam goes in. We don’t foam over degraded fill. We clear it, air-seal the top plates, and then apply the foam so it bonds to the framing, not to a layer of 70-year-old dust.
Closed-Cell for Structural and Air Sealing
Closed-cell foam adds rigidity and blocks air movement, which matters in Bloomington because unpermitted addition walls often leave odd seams where conditioned air leaks out all summer. At roughly $2.50 to $4.50 per board foot in this area, closed-cell is the higher-priced option, but in older homes with irregular framing it earns its keep.
Open-Cell for Full Cavity Coverage
Open-cell runs about $1.50 to $2.50 per board foot around Bloomington and expands more aggressively, which makes it the better fit for oddly shaped cavities and the gaps left behind by 1970s bump-out additions. It’s also the workhorse for attic decks where you need to seal heat out but don’t need the structural boost of closed-cell.
Spray Foam Attic Insulation in Bloomington
Spray foam attic insulation in Bloomington deals with an August reality that no spreadsheet captures: attics here hit 140°F, and that heat soaks through the ceiling into living space until the AC never shuts off. If you’re on the west side near the old dairy farms, your attic may still hold original sawdust or newspaper that has compacted to nearly nothing. We remove it, foam the deck, and the difference is immediate.
Attic foam in Bloomington typically ranges from $2,800 to $7,500 for a full single-story retrofit. That depends on square footage, roof pitch, whether we need to remove old fill first, and whether the rim joist gets treatment too. You’ll know your exact number before we start, in writing, with the Kingswell Guarantee attached.
Rim Joist Sealing
In Bloomington homes, the rim joist is where the wall meets the foundation, and it’s a favorite entry point for dust, heat, and the occasional rodent. Closed-cell foam around the rim joist stops that transfer and stiffens the sill. It’s a smaller job, usually in the $800 to $2,000 range, but it pays back year-round.
Roof Deck Foaming
Foaming the underside of the roof deck turns your attic into a semi-conditioned space, which is the single most effective thing you can do in a Bloomington home with no attic ventilation to speak of. The foam seals the deck, blocks radiant heat, and stops the stack effect that pulls hot air down into the house. Expect this to run $1,800 to $5,500 depending on roof size and foam depth.
Trusted Brands We Service in Bloomington
We install and service eight leading insulation brands because Bloomington homes don’t all need the same foam. Demilec closed-cell works well for the rim joist and roof deck work we do on older dairy-farm homes. Owens Corning and Johns Manville products give us options for open-cell attic applications and hybrid systems. Knauf rounds out the lineup when a budget-conscious retrofit calls for a hybrid approach. Because we’re not tied to one manufacturer, the recommendation you get is based on what your house needs, not what happens to be stacked in the warehouse. We keep common materials staged for Bloomington jobs, so turnaround is fast once your written quote is approved.
Common Spray Foam Insulation Problems We See in Bloomington Homes
- Compacted sawdust and newspaper fill. On the west side near the old dairy farms, original insulation from the 1950s and 1960s has settled to less than an inch. It’s doing nothing, and it has to come out before foam goes in.
- Settled fiberglass batts. Bloomington’s wide temperature swings make older fiberglass lose its loft fast. We regularly see batts slumped at the bottom of wall cavities, leaving the top foot of every stud bay wide open to heat transfer.
- Odd cavities from unpermitted additions. Unincorporated county building history means varied lot sizes and plenty of add-ons that never saw a plan review. Spray foam fills those irregular spaces completely, where batt insulation would leave gaps.
- Nonstop AC in August. When attic temperatures hit 140°F, the ceiling becomes a radiant heat panel. Homeowners assume the AC is failing. What’s actually failing is the attic insulation, and foam on the roof deck fixes it at the source.

FAQs About Spray Foam Insulation in Bloomington
If your home on the west side near the old dairy farms has never been reinsulated, there’s a good chance the original fill is still up there, compacted to a fraction of its original depth. You can check by looking in the attic hatch for loose gray or tan material, or by checking whether your ceiling feels warm to the touch on a hot afternoon. Spray foam cannot go over degraded sawdust or newspaper. The old fill has to be removed first so the foam can bond to the framing and actually seal. Call (831) 263-0387 and we’ll inspect it for free.
Yes. Foaming the roof deck turns the attic into a semi-conditioned space and blocks the radiant heat that pushes attic temperatures toward 140°F in August. In pre-code Bloomington homes, the result is a measurable drop in ceiling temperature within a day of application, and the AC finally gets a break. The exact temperature outcome depends on roof color, ventilation, and foam depth, but you’ll feel the difference immediately.
In many cases, yes. Bloomington is unincorporated San Bernardino County, and retrofits that involve removing old insulation, sealing rim joists, or changing attic ventilation can trigger county permit review depending on the scope. We handle the permit paperwork and county inspections as part of the job so you never have to sort it out yourself. We’ll tell you up front whether your specific project needs one, and the written price we give you includes any permit costs as a line item.
That’s exactly what spray foam does best. Unlike batt insulation, which leaves gaps in non-standard cavities, foam expands to fill whatever shape the framing presents. We work on Bloomington homes with unpermitted additions, bumped-out walls, and cavities that were never built to a standard 16-inch spacing. The foam conforms, seals, and insulates in one pass, which is why it’s the right call for older county homes with irregular construction.
We use Demilec closed-cell for most Bloomington attic and rim joist work because it handles the high heat without losing performance and adds rigidity to old framing. For open-cell applications, we draw from Owens Corning and Johns Manville product lines. the material choice depends on your roof pitch, cavity depth, and budget, and we’ll show you the exact product spec in your written quote before any work starts. Call (831) 263-0387 to talk through the options.
