Insulation Company in Redondo Beach, CA
Blown in insulation solves the most common problem we see in Redondo Beach: older homes with empty wall cavities and attics that never got proper coverage when they were built. Most of the beach bungalows and tract houses in 90277 and 90278 either have no insulation at all or a thin, settled layer that stopped working years ago. We’re a dedicated insulation contractor, not a generalist, and we carry the products that match Redondo Beach’s coastal moisture conditions. Call (833) 356-0182 for a free estimate on your home.
Why Redondo Beach Homes Are Different
The marine layer changes everything about how insulation performs here. Homes within a mile or two of the coast in 90277 sit in cool, damp air for much of the year, and that humidity finds its way into attics, wall cavities, and crawlspaces. Standard fiberglass batts installed without attention to vapor barriers can trap moisture against framing, which leads to mold and rot over time. We see condensation staining on rafters in older beach bungalows west of Pacific Coast Highway on a regular basis, especially in homes that still have their original open attics.
The housing stock makes it more complicated. Redondo Beach is full of 1920s through 1950s beach bungalows with uninsulated exterior walls and unvented attics, and 1960s and 70s tract homes and condos in 90278 that were built when energy codes barely mentioned insulation. Many of these homes still have knob-and-tube wiring in the walls, which rules out dense packing with cellulose until the electrical is addressed. Salt air corrodes fasteners, duct straps, and vent screens faster than it does inland, so we inspect those details before we add material on top of them.
The good news is that the cool climate means Redondo Beach homes don’t need the same heavy cooling loads as inland cities. What they need is a strategy that handles moisture first, then adds the right R-value for the space. That is exactly what we plan for on every estimate.
Our Main Redondo Beach Services
These two services account for most of the calls we get from Redondo Beach homeowners, so we’ve built dedicated pages for each one.
Attic Insulation in Redondo Beach
Older attics in Redondo Beach are rarely insulated to current standards, and the ones that are often have batts that have settled or gotten damp from marine air. We inspect the existing ventilation, check for moisture issues, and then recommend the right material, whether that is blown-in fiberglass, cellulose, or a different approach entirely. Homes in 90277 with their original open attics need a vapor barrier plan before anything else goes in. See the full scope of attic work here: Attic Insulation in Redondo Beach.

Spray Foam Insulation in Redondo Beach
Closed-cell spray foam is often the right answer for Redondo Beach homes with condensation problems, especially in unvented attics and rim joists near the crawlspace. It creates an air and moisture seal that batts cannot match, which matters a lot when salt air is constantly working against your framing. We install Icynene and Demilec systems, both of which require trained and authorized installers. Read more about the options and what they cost here: Spray Foam Insulation in Redondo Beach.

Blown In Insulation in Redondo Beach
Blown in insulation is the most practical way to add coverage to finished Redondo Beach homes without tearing open walls. We drill small access holes, blow loose material into the cavities, and patch the holes cleanly, which works especially well in the 1920s and 50s bungalows in 90277 that were built with empty exterior walls. The material fills around existing wiring, plumbing, and blocking far better than batts ever could, and it is usually the most affordable way to meaningfully cut heating bills in a coastal climate.

Cellulose Insulation
Signs you need it
Your exterior walls feel cold to the touch in winter, rooms facing the ocean stay chilly, or you hear more street noise than you used to.
What it costs in Redondo Beach
Blown-in cellulose for walls or attics in Redondo Beach typically runs $1.50 to $3.50 per square foot installed.
How we do it
We drill access holes, blow GreenFiber cellulose to the specified density, then patch and texture the holes to match the existing surface.
Blown In Attic Insulation
Signs you need it
The existing attic insulation has settled below the top of the joists, or you can feel heat radiating through the ceiling on warm afternoons.
What it costs in Redondo Beach
Blown-in attic insulation in Redondo Beach generally costs $1.50 to $3.50 per square foot installed, depending on depth and material.
How we do it
We air-seal the attic floor penetrations, blow the material to the target depth with a calibrated machine, and verify the final R-value across the entire attic floor.
Blown In Fiberglass Insulation
Signs you need it
You want a non-settling material with predictable thermal performance and do not want the added weight of cellulose.
What it costs in Redondo Beach
Blown-in fiberglass in Redondo Beach typically runs between $1.50 and $3.50 per square foot installed.

We use Johns Manville or Knauf blown fiberglass, adjusting the machine settings to achieve the correct net coverage without over-burying the soffit vents.

The attic has hard-to-reach corners, shallow cavities, or a mix of access heights that batts cannot cover evenly.
What it costs in Redondo Beach
Loose fill insulation in Redondo Beach runs $1.50 to $3.50 per square foot installed.
How we do it
We use a fill tube to reach every corner, level the material across the entire space, and check for blocked vent baffles before finishing.

How long does blown in insulation last in Redondo Beach’s climate?
Blown-in fiberglass lasts the life of the home; cellulose can settle slightly but remains effective for decades. The bigger concern in Redondo Beach is moisture, which is why we verify ventilation and vapor control before installing.
Can you blow insulation into walls without removing drywall?
Yes. We drill small 1-2 inch access holes from the exterior or interior, blow the material in, then patch and paint to match. Most Redondo Beach homes are good candidates for this approach. Call (833) 356-0182 to confirm yours.

What Redondo Beach Customers Say
"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."
— Vikram Singh"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."
— Adam Thompson"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Laura Ackerman
