Spray Foam Insulation in Cerritos — Same-Day Service, Done Right the First Time

Fast, Reliable Spray Foam Insulation Across Cerritos

Spray foam insulation in Cerritos typically runs $2.50 – $4.50 per square foot for open-cell and $4.00 – $7.50 for closed-cell, installed. Most jobs in Cerritos take one to two days, and we schedule most estimates within 48 hours. The catch with this city specifically: almost every home here was built between 1965 and 1975, which means the foam work we do is rarely a clean application onto fresh framing. It’s a removal, air-sealing, duct-restoration, then foam job. Call (866) 605-6949 for a free estimate and we’ll walk the attic with you before quoting anything.

We’re Hollywood Insulation Co, and we’ve worked enough attics in the 90703 zip code to know exactly what’s waiting up there. Cerritos homes share a very specific DNA: wood-frame, stucco-clad, low-pitch roofs, and original insulation that stopped doing its job two decades ago. That’s not a knock on the homes. It just means the right fix here is different than in a newer city like Irvine.

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

Local homeowners call us because we don’t treat a 1972 Cerritos tract home like a blank slate. We know the roof pitches, the original duct layouts, and the way 50-year-old R-11 batts have slumped off the joists. We know the afternoon sun here bakes attics past 140°F even when the coastal morning feels mild. That’s the real reason Cerritos needs spray foam done differently.

Noel Camacho runs our insulation crew, and he’s the person who’ll look at your attic and tell you honestly whether open-cell Icynene against the roof deck makes sense, or whether the better play is sealing the ducts first and then adding blown-in cellulose. We carry Spray Foam Insulation systems from Icynene and Demilec, but we also install GreenFiber cellulose, Rockwool mineral wool, and three fiberglass lines. We recommend what fits your house, not what’s on the truck.

Because we’re a dedicated insulation contractor, our technicians spend every workday diagnosing thermal bypasses and air leakage in attics just like yours. We’re not a general contractor squeezing insulation between kitchen remodels. That focus shows up in the details: we air-seal the top plates and duct boots before we spray, we check the existing radiant barrier instead of spraying over it, and we don’t leave a job until the attic actually holds its temperature.

Response time to Cerritos is typically same-week for estimates, and emergency or time-sensitive jobs can often be scheduled within a few days. We work throughout 90703, from the neighborhoods around Cerritos Park East down to the commercial corridor along South Street, and every quote is free.

Open Cell Spray Foam in Cerritos

Open cell spray foam is the workhorse for Cerritos attics, because it solves the three problems these houses actually have: perished batt insulation, unsealed top plates, and sagging duct runs pulling 140°F attic air into your supply registers. In a low-pitch tract attic, we spray open-cell directly against the underside of the roof deck, bringing the attic inside the conditioned envelope and letting the ducts stop fighting the heat. Open-cell runs $2.50 – $4.50 per square foot installed in Cerritos, and it’s our most common recommendation for 1970s-era homes here.

Air-sealing before the foam goes in

We won’t spray open-cell over the original radiant-barrier staples or collapsed batts without addressing what’s underneath. The top plates, wire penetrations, and duct boots all need sealing first. If we skip that step, the foam traps the same leaks we’re supposed to fix.

Why open-cell suits the Cerritos climate

Cerritos doesn’t need the thermal mass of closed-cell in most attics. The real problem is air movement and radiant heat. Open-cell Icynene seals the air leaks and dampens the heat transfer, and it costs roughly half what closed-cell runs per board foot. That matters when you’re insulating a 1,600-square-foot ranch on a 50-year-old budget.

Spray Foam Insulation Contractors in Cerritos

Spray foam insulation contractors in Cerritos should be able to show you exactly which areas of your attic are leaking before they quote a single square foot. We bring a thermal camera to every estimate, because in these 1970s tracts, the duct runs and top plates are usually leaking more than the ceilings are under-insulated. The contractor you choose should be fluent in the specific failure modes of Cerritos-era construction, not just spray foam in general. Closed-cell jobs here run $4.00 – $7.50 per square foot, and rim joist or garage ceiling work falls in similar ranges depending on access.

What a proper Cerritos foam job includes

Removal of the collapsed original batts, air-sealing the top plates and duct boots, then spray foam applied to the roof deck or walls. If the flex ducts are sagging off the plenum, we re-hang and seal those before the foam goes in. The foam is the last step, never the first.

Garage and rim joist applications

Garage ceilings over living space are a common source of hot spots in Cerritos ranches, especially along the front of the house where the afternoon sun hits the door assembly. Rim joist spray foam is another targeted fix for homes with pier-and-beam sections at the back. Both jobs are smaller in square footage but high-impact for comfort.

Trusted Brands We Service in Cerritos

We install Demilec closed-cell for walls and garage ceilings, Icynene open-cell for roof decks, and we keep GreenFiber cellulose on hand for the attics where a hybrid approach makes more financial sense. Cerritos homeowners sometimes ask for a specific brand by name after reading about it, and we can usually accommodate that without slowing the job down. Because we stock materials locally and schedule crews specifically for Cerritos, turnaround is faster than it would be if we were hauling supplies down from a distant warehouse. Eight brands, one honest recommendation, and no pressure to upsell you into a foam system you don’t need.

Common Spray Foam Insulation Problems We See in Cerritos Homes

• Collapsed original R-11 batts. The fiberglass in these 1970s attics has literally baked for five decades. It’s slumped off the joists, and adding foam on top without removing it just compresses the mess and traps heat. We pull the old batts before we spray.
• Unsealed 1970s duct collars and plenums. Flex runs off the supply plenum were often taped, not mastic-sealed. After 50 summers of heat cycling, those collars are cracked, and the ducts are leaking conditioned air into a 140°F attic. Spraying foam without fixing the ducts means you’re insulating a leaky system.
• Radiant-barrier staples blocking inspection. Many Cerritos attics have an early aluminum radiant barrier stapled to the rafters. It’s usually torn and sagging. It also hides the sheathing and venting from view, so a sloppy spray job just locks in whatever moisture or damage was already behind it. We remove or work around it deliberately.
• Low-pitch roof decks with almost no workspace. Cerritos roof lines run shallow. In a tight attic, it’s tempting to rush the foam application and bridge over duct boots instead of sealing them. We’re slow and methodical in those spaces because the duct sealing is the part that actually quiets the afternoon temperature swings.
