Why Aliso Viejo Insulation Co Is Inglewood’s Preferred Spray Foam Insulation Company
Inglewood homeowners don’t have the same houses as people in El Segundo or Torrance. Most of the homes here were built between 1920 and 1960, long before California’s Title 24 insulation mandates. That means single-wall construction, lath-and-plaster interiors, and attics that have never been properly sealed. A contractor who mostly works in newer subdivisions will walk into your 90302 bungalow and miss the knob-and-tube wiring, the baked-out eave batts, the raised foundation with exposed subfloor. We don’t miss those things, because we see them every week in Inglewood.
Nate Calloway built this company around material-agnostic advising. We recommend what your house actually needs, not what’s easiest for us to install. That’s why we carry both Icynene and Demilec spray foam systems, along with Rockwool mineral wool and GreenFiber cellulose. For an Inglewood attic near the airport corridor, that might mean closed-cell foam on the roof deck plus a radiant barrier. For a pier-and-beam bungalow, it means sealing the rim joists first. The right call depends on your structure, not our inventory.
Spray Foam Insulation Contractors in Inglewood
Spray Foam Insulation Contractors in Inglewood are the tradespeople who apply expanding polyurethane foam to seal and insulate the thermal envelope of a home. In Inglewood, the job almost always starts in the attic, because most houses here predate Title 24 and have no wall cavities to fill. Our Spray Foam Insulation team approaches every job by first identifying where air is actually moving through your home, then matching the foam chemistry to the application. Closed-cell Icynene delivers high R-value and moisture resistance for roof decks. Open-cell Demilec works well for sound attenuation in interior walls and floor cavities. A typical Inglewood attic project runs $3,500 to $6,800 depending on square footage and access.
Closed-Cell Roof Deck Application
In Inglewood’s warm, coastal-influenced climate, heat gain through the roof is the primary comfort problem. Closed-cell foam sprayed directly onto the underside of the roof deck creates an air seal and insulating layer that keeps attic temperatures close to living-space temperatures. That matters when your ductwork runs through the attic, as it does in most 1950s stucco tract homes here.
Rim Joist and Subfloor Sealing
Raised-foundation bungalows along Crenshaw and Prairie Avenue have rim joists that let outside air pour under the house. We seal those with closed-cell foam before addressing any other plane. It’s a smaller job, often $900 to $1,400, but it changes how the whole floor feels in winter.
Spray Foam Attic Insulation in Inglewood
Spray Foam Attic Insulation in Inglewood homes is the process of applying foam to the roofline, attic floor, or gable walls rather than laying fiberglass batts. For Inglewood specifically, we recommend attic-deck application far more often than attic-floor work, because most homes here have HVAC ducts and air handlers sitting in the attic. When the attic isn’t conditioned, those ducts cook in the heat. Sealing the roofline with closed-cell Icynene brings the ducts into the conditioned space, and that’s where the real efficiency comes from. Expect to pay $3,800 to $7,200 for a full roof deck application on a 1,200 to 1,800 square foot Inglewood home.
Eave Air Sealing and Baffle Work
Near the 405 and 105 interchange, wind-driven dust works its way into attic spaces through unsealed eaves. We regularly find the outermost batts compacted and useless. Sealing the eave line with foam and installing proper baffles keeps that dust out and lets the foam assembly do its job. This is a $600 to $1,200 add-on for most Inglewood attics, and it’s almost always worth doing at the same time.
Trusted Brands We Service in Inglewood
We’re authorized to install insulation from eight manufacturers, which means we’re never stuck pushing one product line. For Inglewood spray foam work, we lean on Icynene and Demilec for their closed-cell and open-cell systems, and we stock Owens Corning and Rockwool products for complementary work like mineral wool fire barriers and fiberglass reinforcement where the project calls for it. Because we order directly from manufacturer distribution, turnaround on specialty materials for Inglewood jobs is fast. When a homeowner on La Brea Avenue needs a specific foam density for a quirky 1930s roof pitch, we can get it scheduled without waiting on a middleman.
Common Spray Foam Insulation Problems We See in Inglewood Homes
- Foam sprayed over knob-and-tube wiring. Houses built in the 1920s and 1930s often still have active knob-and-tube circuits in the attic. Closed-cell foam traps heat around those wires, which can create a fire risk. We inspect before we spray, and if the wiring is live, we recommend an electrician address it first.
- Roof deck foam applied over unsealed eave batts. If the original fiberglass at the eaves has blown back or compacted, the foam assembly leaks at the edges. Wind-driven dust from the airport corridor gets in, and the thermal seal fails. Proper eave prep is non-negotiable in Inglewood.
- Over-spraying open-cell foam on raised foundations without rim sealing. Some contractors will sell a full attic job but skip the rim joists on pier-and-beam homes. The floor plane stays drafty, and the homeowner wonders why the house still feels cold in January. We address the foundation perimeter before or alongside the attic.
- Foam applied to unvented rafters without addressing existing moisture. Inglewood’s marine layer can leave attics damp in the mornings. If foam goes over damp sheathing, it locks moisture in. We check roof condition and ventilation history before recommending a sealed-attic approach.

FAQs About Spray Foam Insulation in Inglewood
You spray foam the attic roof deck and rim joists, not the walls. Lath-and-plaster walls from the 1920s and 1930s have no cavity to fill, and drilling them creates a mess without much thermal gain. We focus on sealing the attic and foundation perimeter, which addresses the bulk of your heat gain and air leakage. Call (877) 352-4780 and we’ll assess your specific house.
Because spray foam air-seals, not just insulates. Fiberglass batts don’t stop air movement, and near the freeway corridor, that means dust, noise, and hot air move through your attic continuously. Closed-cell foam on the roof deck locks the assembly together and keeps your ductwork in conditioned space. The improvement is measurable within a week.
Yes. Inglewood homes built before 1940 frequently still have knob-and-tube circuits in the attic. Closed-cell foam traps heat around those wires, and most code inspectors won’t pass a foamed assembly over active knob-and-tube. We check for it during the walk-through and will tell you plainly if an electrician needs to come out first. Call (877) 352-4780 to schedule an inspection.
It’s worth it for the air sealing and duct conditioning, not just the R-value. Inglewood’s problem is heat gain through the roof and noise from the 405, not deep winter cold. A sealed attic with foam on the roof deck keeps afternoon heat from baking your ductwork and cuts traffic noise that standard batts don’t address. Most Inglewood homeowners notice the difference in the first warm week.
We seal the rim joists with closed-cell foam first, then assess the subfloor. On pier-and-beam homes throughout 90306 and 90307, the rim seal stops the stack effect that pulls outside air under the house and up through the walls. If the subfloor itself needs attention, we can apply open-cell foam between joists. Call (877) 352-4780 for a specific recommendation on your foundation type.
