Insulation Company in Venice, CA
Blown in insulation in Venice addresses a specific problem: most homes built between the 1920s and 1950s here went up with empty wall cavities and thin or nonexistent attic coverage. We’re Fontana Insulation, and we’ve served Venice since 2011, installing blown-in, attic, and spray foam insulation across the 90291 and 90294 ZIP codes. If your bungalow on a walk street feels damp at night or your west-facing rooms bake after noon, call (866) 271-1602 for a free estimate.
Why Venice Homes Are Different
Venice’s housing stock is unlike almost anywhere else in Los Angeles. The 1920s beach cottages near the canals and the postwar bungalows east of Lincoln Boulevard were framed before building codes required insulation. Many still have original knob-and-tube wiring running through uninsulated wall cavities, which matters because you cannot simply blow cellulose around live knob-and-tube without addressing fire risk. We check for that before quoting.
The marine layer changes the problem entirely. In Venice, nights stay cool and damp year-round, so wall cavities and attic framing sit near dew point more often than not. The real insulation problem here is not heat gain. It is condensation inside walls and attics. A poorly sealed insulation job traps moisture against old plaster and fir studs, and within a season you get paint blistering, musty odors, or mold behind the lath.
Walk-street and canal-side cottages add another layer: many were built with no attic venting and no vapor barrier. Blowing insulation into those walls without first air sealing penetrations and adding controlled ventilation can make a damp house worse. We plan Venice jobs as a thermal and moisture system, not a one-material install.
Our Main Venice Services
Most Venice homeowners call us about two things: getting insulation into an attic that currently has none, and air sealing old wall cavities with spray foam where blanket material cannot reach. Here is how each works in Venice specifically.
Attic Insulation in Venice
Attics in Venice are tight, often with flat or low-slope roofs and limited access. In the 1920s bungalows, there may be no venting at all, and the ceiling below is usually original plaster over 1x lath. We blow cellulose or fiberglass to the R-value the structure supports, but only after checking for knob-and-tube wiring and sealing bypasses around plumbing stacks and old can lights. The goal is a consistent thermal boundary, not just material on the floor. See Attic Insulation in Venice for full detail on materials and pricing.
Spray Foam Insulation in Venice
Spray foam earns its cost in Venice when walls cannot be opened or vented. For a 1940s duplex with empty stud bays and original stucco, closed-cell foam injected through small holes air seals and insulates in one pass, and it handles the moisture issue better than any fiber product. For west-facing rooms on the second floor of a remodel, open-cell foam against the roofline cuts radiant heat while letting the assembly dry toward the interior. Spray Foam Insulation in Venice covers the two foam types and typical costs.

Blown In Insulation in Venice
Blown in insulation in Venice is usually the right call for attics in the 1920s and 1930s cottages that have never had coverage, and for wall cavities in older homes where the plaster is too good to tear out. The marine layer matters here: loose fill performs best when the cavity is air sealed first, so the insulation is not drawing damp coastal air through old framing. We install Blown In Insulation as a three-step job: seal penetrations, verify wiring, then blow to the target R-value.
Cellulose Insulation
Signs you need it
Rooms that feel clammy at night, unusually high summer cooling bills given how mild Venice summers are, or attic dust migrating through ceiling cracks into living space.
What it costs in Venice
Cellulose blown into a Venice attic typically runs $1.50 to $3.50 per square foot installed, including the prep work older homes need.
How we do it
We air seal ceiling penetrations and top plates, confirm the wiring is safe to cover, then dense-pack or loose-blow GreenFiber cellulose to the R-value the attic depth allows.
Blown In Attic Insulation
Signs you need it
Your attic is empty or has a few inches of settled, decades-old material, and the top floor runs 10 to 15 degrees warmer than the rest of the house by late afternoon.
What it costs in Venice
Blown in attic insulation in Venice averages $2.00 to $5.00 per square foot, including removal of any failed material and air sealing around penetrations.
How we do it
We remove any compromised material, seal around plumbing vents and electrical penetrations, blow fiberglass or cellulose to the specified R-value, and leave the attic tidy.
Blown In Cellulose Insulation
Signs you need it
Drafts near baseboards in a 1940s or 1950s bungalow with plaster walls, especially on the ocean side of the house, indicating empty wall bays.
What it costs in Venice
Blown in cellulose for walls in Venice is typically $2.00 to $5.00 per square foot, though access through stucco adds labor compared to open framing.
How we do it
We drill small holes through exterior stucco or interior plaster, dense-pack cellulose into each bay at pressure, then patch and texture match the holes.
Blown In Fiberglass Insulation
Signs you need it
An attic with exposed framing and no rodent or water history, where you want a material that settles less over time and carries a long manufacturer warranty.
What it costs in Venice
Blown in fiberglass for a Venice attic runs $1.00 to $3.50 per square foot, a lower-cost option than spray foam for open, vented attics.
How we do it
We air seal the attic floor, verify venting is adequate, then blow Johns Manville or Knauf fiberglass to a consistent R-value across the full attic.
Loose Fill Insulation
Signs you need it
Irregular attic spaces with tight corners, low slopes, and odd framing that batts cannot fit around without gaps and compression.
What it costs in Venice
Loose fill in a small or awkward Venice attic generally costs $1.50 to $4.00 per square foot, with the higher end reflecting difficult access.
How we do it
We run a hose into the attic, fill every cavity to the target depth, and hand-check the coverage with depth markers so there are no thin spots.
What Blown In Insulation Costs in Venice
| Item | Typical range in Venice |
|---|---|
| Blown in attic insulation | $2.00 – $5.00 per sq ft |
| Blown in wall insulation | $2.00 – $5.00 per sq ft |
| Cellulose insulation | $1.50 – $3.50 per sq ft |
Is blown in insulation worth it in Venice’s mild climate?
Yes, because the issue is moisture and drafts, not just temperature. A sealed and insulated attic keeps damp marine air out of the house, which protects plaster and reduces musty odors, even when temperatures are moderate. Call (866) 271-1602 for a free attic assessment.
Can you blow insulation into walls with knob-and-tube wiring?
No. Blowing insulation over live knob-and-tube wiring is a fire hazard and violates code. We inspect first, and if knob-and-tube is present, we recommend the appropriate electrical remediation before any insulation goes in. Call (866) 271-1602 to schedule an inspection.

What Venice 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
