Insulation Company in Tujunga, CA
Tujunga homes sit where the San Fernando Valley heat meets mountain canyon cold, and blown in insulation is usually the first fix we recommend. Most houses here were built between the 1920s and 1950s, before attic insulation was standard practice, which means heat pours out in winter and pours in during summer. Fountain Valley Insulation works across three methods and eight manufacturer brands, so we match the material to your home rather than forcing one product on every job. Call (833) 390-3099 and we’ll tell you straight whether blown in cellulose, fiberglass, or spray foam fits your Tujunga house.
Why Tujunga Homes Are Different
Tujunga sits at the mouth of Big Tujunga Canyon on the Angeles National Forest edge, and the elevation changes everything about how insulation performs. Summer afternoons hit harder than the basin floor, while winter nights drain cold air down from the mountains, so homes here need insulation sized for a real heating load, not just air conditioning. Santa Ana wind events add another layer: canyon-facing ridges get hammered, and wind-driven heat loss through attics and rim joists shows up on utility bills month after month.
The housing stock compounds the problem. Older mountain-town bungalows and cabins from the 1920s through 1950s often have no original attic insulation at all, or a thin layer that settled decades ago. Additions and converted garages created awkward framing pockets and uneven ceiling planes that complicate blowing in loose fill. We routinely open attics in Tujunga and find knob-and-tube wiring still active, which changes how we approach air sealing and material placement. Homes on canyon-side slopes and ridge streets have their own quirk: wind scours attics so loose-fill drifts against the leeward roof deck, leaving bare drywall on the windward side. Re-leveling and baffling after wind season is a local staple, not an upsell.
This is also wildfire-interface territory. Many Tujunga homeowners ask about fire-resistant and ember-resistant attic assemblies, and that’s a question flat-valley cities rarely raise. Mineral wool and certain insulation details matter more here than they do ten miles south.
Our Main Tujunga Services
Two services dominate the calls we get from Tujunga homeowners: attic insulation upgrades and spray foam for hard-to-reach or under-insulated spaces. Both solve different problems, and we’ll tell you which one your house actually needs.
Attic Insulation in Tujunga
Most Tujunga attics were under-insulated from the day they were built, and decades of Santa Ana winds have redistributed whatever loose fill was added later. Attic work here starts with a full inspection: we look at framing irregularities, check for knob-and-tube wiring that needs to be addressed before we blow anything in, and measure where insulation has drifted or settled. Then we specify the right material and depth for a real heating and cooling load. For the full breakdown on attic work in Tujunga, see Attic Insulation in Tujunga.
Spray Foam Insulation in Tujunga
Spray foam earns its keep in Tujunga’s sloped ceilings, converted garages, and canyon-side additions where fiber batts never fit right. Closed-cell foam air-seals and insulates in one pass, which matters when wind-driven air moves through rim joists and wall cavities. We install Icynene and Demilec open- and closed-cell systems, two spray foam specialists most general insulation contractors don’t carry. Read the full scope at Spray Foam Insulation in Tujunga.

Blown In Insulation in Tujunga
Blown in insulation is the most common upgrade we install in Tujunga because it conforms to the odd framing, low slopes, and irregular cavities that define older foothill construction. Houses from the 1920s through 1950s were built with little or no attic insulation, and what’s up there now is often settled, wind-drifted, or missing entirely across whole sections of ceiling. For a deeper look at the method itself, see our Blown In Insulation page.
Cellulose Insulation
Signs you need it
Your attic insulation measures under six inches deep in most spots, or you can see bare drywall from the attic hatch.
What it costs in Tujunga
Blown in cellulose in Tujunga typically runs $1.50 to $3.50 per square foot installed, depending on depth and attic access.
How we do it
We air-seal the ceiling plane, install baffles at the eaves, then blow cellulose to the specified depth and re-level any drifted areas.
Blown In Fiberglass Insulation
Signs you need it
Rooms over the garage or addition stay cold in winter despite the furnace running, a classic sign of missing or compressed fiberglass.
What it costs in Tujunga
Blown in fiberglass in Tujunga typically falls between $1.20 and $3.00 per square foot installed.
How we do it
We dense-pack or loose-fill fiberglass to the target R-value, working around existing framing and any active wiring we’ve flagged during inspection.
Loose Fill Insulation
Signs you need it
Wind scouring has pushed old insulation into drifts, leaving the windward side of your attic nearly bare while the leeward side piles up 18 inches deep.
What it costs in Tujunga
Re-leveling and topping off loose fill in Tujunga typically runs $1.00 to $2.50 per square foot when no major air sealing is required.
How we do it
We rake and redistribute existing material, add new loose fill to spec, and install baffles so the next Santa Ana event doesn’t undo the work.
What Blown In Insulation Costs in Tujunga
| Item | Typical range in Tujunga |
|---|---|
| Blown in cellulose (attic) | $1.50 – $3.50 per sq ft |
| Blown in fiberglass (attic) | $1.20 – $3.00 per sq ft |
| Loose fill re-level and top-off | $1.00 – $2.50 per sq ft |
How long does blown in insulation last in Tujunga’s heat?
Cellulose and fiberglass both last decades in Tujunga attics, but wind and settling are the real enemies. A 30-year-old install that’s never been re-leveled is usually underperforming badly. Call (833) 390-3099 for an attic inspection and quote.
Can you blow insulation into the walls of an older Tujunga home?
Yes, dense-pack wall insulation works in many older Tujunga homes, though knob-and-tube wiring must be addressed first. We check for it during inspection. Call us for a straight answer on your house.

What Tujunga Customers Say
"Installed baffles at the soffits so the new insulation didn't block the ventilation, which the previous contractor apparently never considered."
— Hector Vargas"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— David Tran"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."
