B
Insulation Company in Manhattan Beach, CA
Blown in insulation solves a specific problem in Manhattan Beach more than any other service we offer: the older beach bungalow and cottage inventory from the 1950s through 1970s that still has empty stud bays, uninsulated crawl spaces, and ceilings that leak conditioned air into the salt-heavy marine layer. These homes can’t always be retrofitted with batts because the framing is irregular, the sheathing is fragile, and the wall cavities are tight. Blown in cellulose and blown in fiberglass fill the voids and gaps that batt insulation can’t reach without opening walls. If you’re fighting drafts, high summer humidity, or a second floor that never cools, call Fontana Insulation at (866) 271-1602 and we’ll tell you whether loose fill is the right fit for your home in the 90266 or 90267 ZIP.
Why Manhattan Beach Homes Are Different
Manhattan Beach’s rare mix of coastal salt air, marine-layer dampness, and a high concentration of 1950s – 1970s beach cottages and custom rebuilds means insulation choices here must prioritize moisture management and continuous windproofing, not just R-value. Batts installed in a west-facing attic near The Strand can look fine for a decade and quietly degrade from salt spray carried through attic vents during winter storms. We find moisture barriers compromised in ways that simply don’t happen a few miles inland in Torrance or Redondo Beach.
The housing stock splits into two distinct jobs. Original single-story beach bungalows often have uninsulated walls, vaulted open-beam ceilings, and crawl spaces where marine air moves freely. Modern multi-story custom homes built after 2000 usually have high-performance envelope requirements, but those large glazed areas and complex roof lines create their own air-sealing gaps. In both cases, vapor control matters as much as thermal resistance. The onshore breeze that keeps Manhattan Beach cool in August is also a relentless wind-washing force that steals conditioned air from poorly installed insulation.
For any home west of Sepulveda Boulevard, we treat salt-crust buildup on attic vents and fasteners as a normal condition, not an anomaly. That’s the reason we carry materials like Rockwool and closed-cell spray foam that resist moisture damage and hold their shape in damp conditions. A plain fiberglass batt is not a complete answer here without vapor control behind it.
Our Main Manhattan Beach Services
Most Manhattan Beach homeowners call us about two services: the attic insulation that stops the upstairs from turning into a sauna, and the spray foam that seals ocean-facing walls against wind-washing and salt air.
Attic Insulation in Manhattan Beach
Attic insulation in Manhattan Beach is rarely a simple blow-and-go job. In older bungalows, we’re often working around vaulted open-beam ceilings that leave little attic floor to insulate, which shifts the work to the ceiling plane itself. In newer custom homes, we’re air-sealing around recessed lights, HVAC chases, and the complex roof lines that architects favor near the hill section. The marine layer means we pay close attention to ventilation before adding insulation, so the added material doesn’t trap fog moisture against the sheathing. Attic Insulation in Manhattan Beach covers the full process, from air-sealing to material selection.
Spray Foam Insulation in Manhattan Beach
Spray foam insulation in Manhattan Beach earns its cost in the walls that face the ocean. Closed-cell foam is the only insulation we install that performs as a moisture barrier and an air barrier at the same time, which is why it’s a frequent recommendation for west-facing homes where salt air pushes through every gap in the sheathing. Icynene and Demilec open-cell foam are the right call for interior applications where sound control matters and the framing needs to breathe. Spray Foam Insulation in Manhattan Beach explains which foam matches each condition in the 90266 and 90267 ZIPs.

Blown In Insulation in Manhattan Beach
Blown in insulation is the most practical way to bring Manhattan Beach homes built before 1980 up to modern comfort standards. The original beach bungalows and cottages scattered across the tree section and the sand section have framing that’s anything but consistent: odd stud spacing, settled foundations, and walls that have already been opened and patched more than once. Loose fill conforms to every one of those irregularities and fills the gaps that rigid batts can’t, which means fewer voids where the persistent onshore breeze can rob conditioned air. For many of these homes, blowing insulation into walls and attics is the difference between a house that holds temperature and one that constantly pulls in damp ocean air through every seam. We’ve handled Blown In Insulation jobs across Manhattan Beach since 2011, and the marine-layer moisture here just makes precision installation more important.
Cellulose Insulation
Signs you need it
Your home has settled insulation in the walls, or you feel drafts in rooms that share walls with the original beach cottage framing.
What it costs in Manhattan Beach
Blown in insulation in Manhattan Beach runs $1.15 to $2.65 per square foot installed, and the marine-air conditions often warrant the denser, moisture-resistant cellulose option.
How we do it
We load GreenFiber cellulose into a calibrated blower, cut access points in each stud bay, and fill the cavity to the specified density while checking for hidden gaps in the old framing.
Blown In Attic Insulation
Signs you need it
Rooms under the attic run ten degrees warmer than the rest of the house during summer afternoons, or your attic batts are sagging and compressed from years of damp marine air.
What it costs in Manhattan Beach
Attic floor blow-ins typically fall somewhere inside that same $1.15 to $2.65 per square foot range, and the exact figure depends on whether we’re topping off old material or starting from bare decking.
How we do it
We air-seal any bypasses around lights and chases first, correct the attic ventilation so the material can dry, then blow a uniform blanket across the entire floor with an insulation blower.
Blown In Cellulose Insulation
Signs you need it
You want an insulation upgrade but don’t want the persistent salt-laden air of Manhattan Beach to break down the material prematurely.
What it costs in Manhattan Beach
Blown in cellulose sits in the middle of the $1.15 to $2.65 per square foot range, and the added density required in coastal attics is already part of how we price the job.
How we do it
We blow GreenFiber cellulose to the manufacturer’s specified density, paying extra attention to the eaves and the top plates where salt-laden air tends to first enter.
Blown In Fiberglass Insulation
Signs you need it
You have an attic with flat, open framing and straightforward access, and you want the most cost-effective loose fill option.
What it costs in Manhattan Beach
Blown in fiberglass starts near the lower end of the $1.15 to $2.65 per square foot range, making it the common choice for flat attic floors where vapor exposure is lower.
How we do it
We run fiberglass blow-in material through a hopper and hose, filling the joist bays to the target depth and verifying thickness every few feet with a depth gauge.
What Blown In Insulation Costs in Manhattan Beach
| Item | Typical range in Manhattan Beach |
|---|---|
| Blown in insulation, walls or attic | $1.15 – $2.65 per sq ft |
| Air-sealing package (attic floor, top plates, can lights) | $0.80 – $1.50 per sq ft |
| Vapor barrier & damp-condition correction | $150 – $400 per treated area |
Can you blow insulation into walls from outside?
Yes, and for Manhattan Beach stucco bungalows it’s often the only way to reach cavities without gutting the interior. We drill small access holes through the exterior, blow the material in, and patch the openings to match. It’s a clean, contained job that most homeowners schedule for a single day.
Does blown in insulation settle in humid coastal air?
Cellulose can settle, which is why we spec a higher installed density in Manhattan Beach’s damp climate. That’s also one reason we favor certain building-science details like vapor checks on the ocean-facing walls. Call (866) 271-1602 and we’ll talk honestly about the material that’ll hold up on your street.

What Manhattan Beach Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Michelle Bennett"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Sarah Fletcher"Work is good and the house is noticeably more comfortable. There was insulation debris left in the hall closet under the attic access that I had to clean up."
— Holly Mercer
