Why Hollywood Insulation Co Is Glendale’s Preferred Spray Foam Insulation Company

We work on Glendale houses built in the 1920s through the 1960s, which means we know what’s behind the lath-and-plaster walls and above the low-pitch ceilings before we ever cut into them. We also handle Reflectix repair in Glendale when radiant barriers are the right solution. Our technicians have foamed attics in the Spanish Colonial bungalows along the Verdugo foothills, post-war tract homes south of Glenoaks Boulevard, and apartment buildings in the 91207 and 91208 corridors where parking is tight and access is through alley-loaded doors. That local familiarity matters when you’re pulling hose through a 1950s duplex with a 3-foot scuttle and knob-and-tube wiring still live in the framing.

Every Glendale project is led by Noel Camacho, who has spent his career in insulation, not as a general contractor doing insulation on the side. That focus shows up in the details: identifying thermal bypasses in old top plates, specifying the right foam density for an unvented low-pitch roof, and knowing when open-cell is the right call versus closed-cell on a west-facing uninsulated wall. Glendale homeowners call us because they want a specialist who can explain why their second-floor bedroom is 15 degrees hotter than the rest of the house, and then actually fix it.

Spray Foam Insulation Contractors in Glendale

Spray foam insulation contractors in Glendale do more than load a rig and spray. The work here means diagnosing why a 1940s bungalow’s west wall has zero insulation while the attic hits 140°F by early afternoon, then choosing the right foam system and installation approach for that specific house. Our Spray Foam Insulation team carries both open-cell and closed-cell systems from Icynene and Demilec, which lets us match the foam to the problem rather than forcing one product onto every job. A standard attic air-seal and open-cell installation for a 1,200-square-foot Glendale bungalow runs $3,200 – $4,800. Closed-cell wall retrofits on uninsulated west-facing walls run $3,800 – $6,400 depending on access and framing conditions.

Closed-Cell for West-Facing Walls

Many Glendale homes built before 1960 have empty wall cavities on their west and south exposures. Closed-cell spray foam acts as both insulation and air barrier in those cavities, cutting the late-afternoon solar gain that bakes bedrooms along the Verdugo foothills. The foam’s density also adds structural racking strength to old balloon-framed walls, which matters on pre-war construction.

Open-Cell for Attic Air Sealing

For attics that need air sealing more than extra R-value, open-cell foam is often the better specification. It expands into top plates, penetrations, and bypasses, and it’s forgiving enough to work around old framing without over-pressuring lath-and-plaster ceilings. In Glendale’s cooling-dominated climate, stopping attic air leakage delivers more comfort per dollar than adding inches of fiberglass.

Spray Foam Attic Insulation in Glendale

Spray foam attic insulation in Glendale homes is about heat rejection first and heating-season performance second. Our technicians spend most of their time in Glendale attics dealing with three things: solar heat radiating through roof decks, air leaks where interior walls meet ceiling joists, and decades of dust and ash that has settled into old blown-in material. A full attic spray foam retrofit for a typical Glendale home runs $2,800 – $5,200, with most of that cost coming from prep work, masking, and air-sealing detail rather than raw foam volume.

Unvented Low-Pitch Attic Roofs

Glendale has thousands of low-pitch roofs on Spanish Colonial and mid-century tract homes where traditional vented attic insulation underperforms. Closed-cell foam applied directly to the roof deck creates an unvented assembly that keeps the entire attic space within the conditioned envelope, which makes a real difference when attic temperatures spike during Santa Ana events.

Knob-and-Tube Workarounds

Before any foam goes in, we identify and flag live knob-and-tube wiring, which is still common in Glendale’s 1920s and 1930s housing stock. Spray foam can trap heat around old wiring and create a code violation if the wiring isn’t properly assessed first. We coordinate with our Glendale customers to have old circuits evaluated or decommissioned before we spray over them.

Trusted Brands We Service in Glendale

We stock and install spray foam systems from Icynene and Demilec, two of the most specified spray polyurethane foam brands in North America. For Glendale customers who need a different approach, we also carry Rockwool mineral wool and CertainTeed fiberglass, which gives us the latitude to specify the right material for the actual condition of your home rather than pushing one product. That breadth matters in Glendale where we’re working around knob-and-tube wiring, uninsulated walls, and attic spaces that have never been touched since the house was built. We keep enough material on our trucks to handle same-day retouches for Glendale customers without sending a crew back to the shop.

Common Spray Foam Insulation Problems We See in Glendale Homes

• Uninsulated west walls in pre-war bungalows. Many 1920s-1940s Glendale homes have empty wall cavities facing the afternoon sun. Closed-cell foam retrofits stop the thermal transfer that makes those rooms unusable from 3 p.m. to sunset.
• Overspray and odor drift in shared-wall apartments. In dense apartment stock off Brand and Glendale Avenue, poorly prepped foam jobs push overspray and off-gassing through shared attics into neighboring rent-controlled units. We mask and ventilate aggressively before spraying in multi-unit buildings.
• Closed-cell foam trapping moisture on unvented low-pitch roofs. Spraying foam too thick on old lath-and-plaster ceilings without addressing roof moisture can trap condensation. We specify foam depth and density based on the roof assembly, not a one-size-fits-all chart.
• Live knob-and-tube buried under old insulation. Before any spray foam work begins in Glendale’s older attics, we check for active knob-and-tube circuits. Foam over live K&T is both a code issue and a real heat hazard.
