Fast, Reliable Spray Foam Insulation Across Orange
Spray foam insulation in Orange costs $2.50 to $7.50 per square foot installed, depending on whether the job calls for open-cell or closed-cell foam and whether we’re insulating an attic, rim joists, or a roof deck. Most Orange projects wrap up in one or two days, and we schedule emergency callouts when a failed insulation job or sudden air-sealing issue needs immediate attention. If you’re losing cooled air through a 1940s attic or dealing with a converted patio that never stops baking in August, call us at (866) 605-6949 for a straight answer and a free estimate.
We know Orange’s housing stock because we work in it every week. The 92863, 92864, 92865, and 92866 ZIP codes cover neighborhoods where homes were built long before spray foam existed, and that changes how we approach every retrofit.
Why Hollywood Insulation Co Is Orange’s Preferred Spray Foam Insulation Company
We’re the Spray Foam Insulation specialist Orange homeowners call when they want someone who actually understands what’s behind their walls. Not a general contractor who occasionally insulates. Our technicians diagnose thermal bypasses, air leakage, and R-value deficiencies every single day. That’s the whole job. When we walk into a 1926 Craftsman bungalow near the Orange Circle or a 1955 tract house off Tustin Avenue, we already know what we’re likely to find: uninsulated cavities, settled batts, or foam that was installed wrong by someone who didn’t understand the house.
Noel Camacho leads our Orange work, and he’s built a reputation for telling homeowners what a house actually needs, not what’s easiest to sell. That’s why we carry eight manufacturer brands across every major insulation category, including Icynene and Demilec for spray foam. You get the material that matches your home’s construction, not whatever happens to be on the truck. Orange customers consistently mention our straight pricing and the fact that our crew shows up when we say we will.
Response time matters in Orange. Summer attic temperatures here climb past 140°F, and when insulation fails, the upstairs rooms become unusable by midafternoon. We typically reach Orange homes the same day for emergencies, and standard installations are scheduled within the week. Estimates are always free, and we’ll give you a written number before any work starts.

Spray Foam Insulation Contractors in Orange
Spray Foam Insulation Contractors in Orange do more than spray foam. The real work is knowing what to do with a 1920s lath-and-plaster wall or a 1950s attic with no ventilation. Our Orange crews handle open-cell and closed-cell applications, rim joist sealing, garage ceiling insulation, and roof deck treatments. The cost ranges from $2.50 per square foot for open-cell foam in accessible attic spaces to $7.50 per square foot for closed-cell foam applied to complex roof decks or tight rim joist areas.
Homeowners call us when rooms won’t hold temperature, when energy bills spike every summer, or when a remodel exposes walls with no insulation at all. Builders call us when they need a specified system, not a guess.
Retrofit Projects and Older Orange Homes
Most of our Orange work is retrofit, not new construction. That means we’re often working inside finished homes, protecting floors and furnishings while we cut access points, remove old material, and air-seal before applying foam. A typical 1,200 square foot attic retrofit in Orange takes one day for open-cell and up to two days for closed-cell roof deck applications.
Air Sealing and Rim Joist Work
Rim joists are one of the most overlooked heat-loss points in Orange’s mid-century tract homes. Sealing them with closed-cell foam runs roughly $8 to $12 per linear foot, and the energy payback in Orange’s hot summer climate is usually noticeable within the first season. This work matters especially in homes where converted patios and add-ons have created irregular building envelopes that leak air in ways standard attic insulation never addresses.
Spray Foam Attic Insulation in Orange
Spray Foam Attic Insulation in Orange typically costs $3,500 to $9,000 for a full attic depending on square footage, access difficulty, and whether we’re insulating the attic floor or the roof deck. Orange’s summer heat makes attic work the highest-impact insulation project most homeowners here will ever do. A sealed attic keeps radiant heat from baking down through your ceilings, which is exactly why July and August are our busiest months in the 92865 and 92866 ZIP codes.
We see a lot of Orange attics with original 1950s batts that have settled to R-4 or less, essentially providing no meaningful resistance to the Southern California sun. Our approach is to remove the old material, air-seal every penetration, and apply foam where it actually matters, whether that’s the attic floor or the roof deck for an unvented assembly.
Roof Deck Foam for Unvented Attics
If your Orange home has an unvented attic or one that can’t be properly vented due to roof design, closed-cell foam on the roof deck is the right call. We use Icynene and Demilec closed-cell systems for these applications, typically at 2 to 3 inches of depth. The attic becomes conditioned space, which resolves the 140°F attic problem permanently rather than just masking it.
Attic Floor Air Sealing and Foam
For vented attics, we focus on air sealing every top plate, wire penetration, and duct chase, then apply open-cell foam to the attic floor. This runs $2.50 to $3.50 per square foot in Orange and dramatically reduces the stack effect that pulls hot attic air into living spaces through gaps in the drywall.
Trusted Brands We Service in Orange
We stock and install Icynene and Demilec spray foam systems for Orange customers, plus fiberglass, mineral wool, and cellulose options from Owens Corning, Johns Manville, CertainTeed, Knauf, Rockwool, and GreenFiber. Carrying eight brands means we’re not bluffing when we say the recommendation matches the house. For a 1948 Orange ranch with open attic access, open-cell Icynene may be ideal. For a converted patio with moisture exposure, Demilec closed-cell makes more sense. We keep materials staged for Orange jobs, so turnaround is fast when you’re fighting a deadline on a remodel or a sale.
Common Spray Foam Insulation Problems We See in Orange Homes
- Foam over knob-and-tube wiring: Orange’s 1920s through 1950s homes often still have live knob-and-tube circuits in attics and walls. Spraying foam directly over this wiring creates a serious fire hazard and fails code. We isolate and remediate wiring before any foam touches it.
- Moisture trapped in Old Towne brick walls: The solid brick construction common in the historic district has no cavity for injection. Applying foam to these walls without addressing drainage and vapor movement causes spalling brick and interior water damage. We use rigid-board or furring solutions instead.
- Bypassed attic penetrations: In Orange’s 1950s tract homes, can lights, duct chases, and plumbing vents create air pathways that let hot attic air move right past the foam. If these aren’t sealed before spraying, energy savings drop significantly.
- Irregular envelopes from add-ons: Converted patios, added bathrooms, and enclosed porches are everywhere in Orange, and each one creates a thermal break where the original house meets the addition. Foam applied without addressing these transition points leaves gaps that undo the whole system.

FAQs About Spray Foam Insulation in Orange
No, you cannot spray foam directly over live knob-and-tube wiring in any Orange home. Foam insulates the wires, traps heat, and creates a fire hazard that also fails building code. We isolate and address the wiring before applying foam, and we’ll walk you through what that process looks like for your specific house. Call (866) 605-6949 if you know your Orange home has original wiring and you want to understand the scope before committing.
Spray foam doesn’t work in solid brick walls with no cavity to fill in Orange’s Old Towne district. Instead, we use interior rigid-board insulation or furring systems that create a new insulated plane on the inside of the brick. This requires more careful detailing around trim and windows, but it’s the correct approach for a wall assembly that simply has nowhere to inject foam. Our crew recently completed exactly this type of retrofit near the Orange Circle, and the homeowners saw immediate comfort gains in their front room.
Closed-cell foam on the roof deck is the right choice for a 1950s Orange tract home with an unvented attic. It provides a high R-value per inch, stops radiant heat from the roof, and creates a conditioned attic space that reduces the strain on your AC system. We use Icynene and Demilec closed-cell systems for these applications, typically $5.00 to $7.50 per square foot. Call (866) 605-6949 and we’ll assess your roof assembly and give you a specific number.
Yes, old insulation should be removed before applying spray foam in Orange attics. Leaving settled 1950s batts or blown material underneath foam creates moisture traps and prevents the foam from adhering properly to the surface it’s meant to seal. We remove the old material, inspect the attic for air leaks and wiring issues, then apply foam to a clean surface. This is standard practice on every attic retrofit we do in Orange.
Yes, spray foam is well-suited to converted patios and add-ons in Orange, especially closed-cell foam for areas with moisture exposure or irregular framing. However, the transition between the original house and the addition must be air-sealed carefully, or the foam won’t deliver the comfort gains you’re expecting. These are exactly the kinds of problem areas we diagnose every week in Orange’s 1940s and 1950s neighborhoods. Call (866) 605-6949 for a free inspection and a plan that addresses the whole envelope, not just the obvious spots.
