Insulation Company in Redondo Beach, CA
Blown in insulation solves the two problems Redondo Beach homeowners feel most: rooms that never hold temperature and energy bills that climb every summer. In the 90277 and 90278 ZIP codes, the marine layer means cool, damp mornings almost year-round, and older wood-frame homes from the 1950s through 1970s leak conditioned air through attics and walls at rates newer construction doesn’t. We’re East Los Angeles Insulation Co, a dedicated insulation contractor serving Redondo Beach since 2018, and our most-requested service here is blown in insulation – fast to install, effective in hard-to-reach cavities, and matched to your home rather than whatever product happens to be on the truck. Call (866) 566-0304 for a free estimate.
Why Redondo Beach Homes Are Different
Redondo Beach doesn’t get the inland temperature swings, but it gets something worse for insulation: salt-laden air and persistent moisture. Homes in the 90277 ZIP code sit close enough to the ocean that morning fog rolls through on a regular schedule, and that moisture finds its way into attics, crawl spaces, and wall cavities. Wood-frame construction with stucco exteriors, common in the beachside tracts built between the 1950s and 1970s, breathes differently than modern sealed envelopes – and when insulation absorbs moisture, its R-value drops and it can hold water against framing. We’ve pulled fiberglass batts out of Redondo Beach attics that weighed twice what they should because years of marine air had soaked through. That’s why we focus on moisture-resistant products here, including closed-cell spray foam for crawl spaces and GreenFiber cellulose with borate treatment for attics. Pier-and-beam foundations in older beachside tracts add another layer: crawl space insulation has to survive occasional saltwater intrusion during winter high tides and heavy rains, especially near the water. A product that works fine in Torrance or Lawndale may be the wrong call a half-mile from the sand.
Our Main Redondo Beach Services
Two insulation services drive most of the calls we take from Redondo Beach homeowners: attic insulation and spray foam. Each has its own dedicated page with full pricing and local detail.
Attic Insulation in Redondo Beach
Most heat loss in Redondo Beach homes happens through the attic, and homes from the 1950s and 1960s often have less than R-19 up there – nowhere near what today’s energy standards call for. We treat attic insulation as a specialty: we inspect for existing moisture damage from the marine layer, check ventilation, and then recommend either blown in cellulose or fiberglass or batts, depending on the attic’s layout and whether you store anything up there. Closed-cell spray foam on the roofline is another option for attics that can’t be properly ventilated. See the full breakdown on our Attic Insulation in Redondo Beach page.
Spray Foam Insulation in Redondo Beach
Spray foam earns its price in Redondo Beach when water intrusion is a concern. Open-cell foam seals air leaks in attics and walls. Closed-cell foam adds structural strength and a moisture barrier, which matters in crawl spaces near the beach where winter tides push saltwater under pier-and-beam homes. We install Icynene and Demilec products, both with established field performance records, and we’re one of the few insulation crews in the area offering genuine choice between open- and closed-cell applications. Details and pricing live on the Spray Foam Insulation in Redondo Beach page.
Blown In Insulation in Redondo Beach
Blown in insulation is our most-requested service in Redondo Beach, and for good reason: it fills the irregular cavities and awkward corners that are common in 1950s and 1960s wood-frame homes, and it can be installed in a single day. In the 90277 and 90278 ZIP codes, the salt-heavy marine air makes moisture resistance a real consideration – we frequently recommend GreenFiber cellulose for Redondo Beach attics because its borate treatment resists mold and pests while providing solid thermal performance. Blown in fiberglass is the right choice when weight is a concern, since it’s lighter than cellulose and less likely to compress older ceiling assemblies. We install both, plus loose fill for hard-to-reach areas, and we’ll help you decide which product fits your home’s construction and moisture exposure.

Cellulose Insulation
Signs you need it
Your attic insulation has settled to under 6 inches deep, or your upstairs rooms run 5-8 degrees warmer than downstairs.
What it costs in Redondo Beach
Blown in cellulose typically runs $1.20 – $2.30 per square foot installed in Redondo Beach, depending on attic depth and access.
How we do it
We air-seal bypasses, verify ventilation, and blow GreenFiber cellulose to the target R-value at consistent density.
Blown In Attic Insulation
Signs you need it
You can see the tops of your ceiling joists through the existing insulation, or your attic insulation looks compacted and darkened from moisture absorption.
What it costs in Redondo Beach
Whole-attic blown in insulation in Redondo Beach commonly falls between $1,500 and $3,200 for a typical 1,200 – 1,800 sq ft home.
How we do it
We remove or top off the existing material as needed, seal penetrations, and blow fresh insulation to an even, code-meeting depth.
Blown In Cellulose Insulation
Signs you need it
Your energy bills have climbed 20% or more year-over-year without a corresponding change in your usage patterns.
What it costs in Redondo Beach
Blown in cellulose attic coverage runs $1.20 – $2.30 per square foot in Redondo Beach, with partial top-offs priced lower than full removals.
How we do it
We use GreenFiber cellulose with borate treatment, applied with calibrated machines to hit the R-value your attic needs without overloading the ceiling.
Blown In Fiberglass Insulation
Signs you need it
You want attic insulation that stays put without adding much weight to older ceiling joists, or you prefer a product that won’t absorb moisture the way untreated cellulose can.
What it costs in Redondo Beach
Blown in fiberglass runs $0.90 – $1.90 per square foot installed in Redondo Beach, making it slightly less expensive than cellulose on average.
How we do it
We blow loose-fill fiberglass to spec at a controlled density, confirming depth with gauge markers so you know exactly what R-value you’re getting.
Loose Fill Insulation
Signs you need it
You have an attic with irregular joist spacing, low-clearance areas, or obstacles like ductwork and recessed lights that make batt installation impractical.
What it costs in Redondo Beach
Loose fill insulation in Redondo Beach typically ranges $0.90 – $2.30 per square foot depending on material and depth.
How we do it
We map the space, protect fixtures, and blow loose fill into every cavity so no gaps remain – then verify final depth with gauge readings.
What Blown In Insulation Costs in Redondo Beach
| Item | Typical range in Redondo Beach |
|---|---|
| Blown in fiberglass (attic, full coverage) | $0.90 – $1.90 per sq ft |
| Blown in cellulose (attic, full coverage) | $1.20 – $2.30 per sq ft |
| Whole-attic project (1,200 – 1,800 sq ft home) | $1,500 – $3,200 |
Prices shift with attic access, existing insulation removal, and how much air-sealing is needed before we blow. Every estimate is itemized and fixed before we start – no surprise line items.
Can you install blown in insulation in a Redondo Beach home without removing the old insulation?
Usually yes. If the existing material is dry and not compacted, we can blow new insulation on top to reach target R-value, which saves on removal labor. If it’s water-damaged or moldy from marine moisture, we’ll recommend removal first. Call (866) 566-0304 and we’ll inspect it.
Is blown in insulation better than batts for a 1960s Redondo Beach house?
For most 1950s-1970s Redondo Beach homes, yes. Blown in material fills irregular joist bays and around obstacles far better than batts ever will, and cellulose adds pest and mold resistance valuable near the coast. Call (866) 566-0304 for a recommendation based on your attic.

What Redondo Beach Customers Say
"He did a blower door test before and after and gave me the numbers. I like being able to see the difference rather than being told about it."
- Gilbert Herrera"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."
- Jason Walsh"Handled the utility rebate paperwork, which knocked a real amount off the final cost."
