Insulation Company in Silver Lake, CA
Blown in insulation is the workhorse solution for Silver Lake’s pre-war housing stock, and it’s what we find ourselves recommending most often when homeowners call us at (833) 390-7079 about rooms that won’t hold temperature. Most homes here were built between 1920 and 1940 with lath-and-plaster walls and empty stud bays, which means we’re almost always retrofitting from scratch rather than topping up existing insulation. The steep hillside lots around the reservoir add a logistical layer: plenty of attics and crawlspaces have no street access at all, so our crews regularly haul hoses and equipment up public stair streets to reach the work. This isn’t a suburban attic top-off job. Silver Lake demands a material and a method that works inside old framing and hard-to-reach cavities.
Why Silver Lake Homes Are Different
Silver Lake’s housing stock runs heavily to 1920s Spanish Colonial and Craftsman bungalows with lath-and-plaster walls, plus hillside dingbats from the 1960s tucked over tuck-under garages and the occasional mid-century post-and-beam with exposed ceilings. Almost none of it was built with meaningful insulation. The 2×4 framing creates shallow, irregular cavities that don’t accept standard batt products cleanly, and the knob-and-tube-era wiring still present in many of these homes means some cavities can’t be filled at all without electrical remediation first.
The climate shapes the work too. Cooling loads dominate here. Radiant heat pours through uninsulated attics from late spring into October, and single-pane windows compound the problem. Winter is mild, but the cold snaps and rain that roll through between December and February make draft sealing around old framing just as important as adding R-value. Homes on the stair streets and hillside alleys, especially around the reservoir, often have no street-facing attic access at all. Our techs routinely run blow-in machines on the sidewalk and feed hoses over rooftops or through alley-side hatches. It changes how we plan every job in the 90026 ZIP.
Our Main Silver Lake Services
Most Silver Lake homeowners reach out about one of two problems: an attic that’s bleeding heat in every direction or air leakage through old framing that no amount of batt insulation will fix. Here’s what each service looks like in this specific housing stock.
Attic Insulation in Silver Lake
Attics in Silver Lake are rarely empty, but they’re almost always under-insulated. We regularly open hatches to find a thin layer of decades-old material settled to R-11 or worse, with big gaps around the access panel and ductwork. Radiant heat from the roof deck turns these attics into ovens by mid-morning, and that heat pushes into living space all afternoon. We remove or top off what’s there, air seal the framing penetrations, and bring the assembly up to current building code levels with blown-in fiberglass or cellulose. For the full breakdown of how we handle Silver Lake’s specific attic conditions, see our Attic Insulation in Silver Lake page.
Spray Foam Insulation in Silver Lake
When a Silver Lake home has exposed post-and-beam ceilings, a crawlspace that stays damp, or walls that can’t be dense-packed because of old wiring, spray foam becomes the right call. Closed-cell foam seals air movement and adds structural rigidity at the same time, which matters on hillside foundations that shift. Open-cell foam handles sound and thermal control in interior walls and rooflines where moisture management is less critical. We run both formulations through our Icynene and Demilec product lines.

Blown In Insulation in Silver Lake
Blown in insulation is the most practical way to add real thermal performance to Silver Lake’s old walls, attics, and floor cavities without tearing open lath-and-plaster or rebuilding framing. Because the material flows into irregular stud bays and settles around obstacles like old plumbing and electrical lines, it fills cavities that batt insulation simply can’t handle. The steep lots and tight alleys around the reservoir make blow-in the preferred method here since it can be installed from above, below, or through small drilled holes in plaster without requiring the kind of workspace that these hillside properties never have. You can read more about the material and method on our Blown In Insulation hub page.
Blown In Attic Insulation
Signs you need it
If your upstairs rooms bake in summer while the attic feels like a sauna, you’re looking at radiant heat moving through an under-insulated ceiling and likely need a top-off or full blow-in.
What it costs in Silver Lake
Blown in attic insulation in Silver Lake typically falls between $1,800 and $3,200 depending on square footage, existing material condition, and depth of coverage needed.
How we do it
We air seal the attic floor penetrations first, then blow the material to the specified depth using a hose run through the attic hatch or a roof vent, settling it evenly across the entire ceiling plane.
Blown In Cellulose Insulation
Signs you need it
You want a denser, higher-R-per-inch option made from recycled content, and you’re willing to address settled old material before adding new.
What it costs in Silver Lake
Blown in cellulose insulation in Silver Lake typically runs $2,200 to $4,000 for a full attic or wall retrofit, with wall jobs falling on the higher end due to access and patching labor.
How we do it
We run GreenFiber cellulose through our blowers at the specified density, dense-packing wall cavities through small holes drilled in plaster or exterior stucco and patched to match afterward.
Blown In Fiberglass Insulation
Signs you need it
You have an open attic or interior wall cavities with no existing insulation and want a clean, non-settling fill applied at a lower material cost than cellulose.
What it costs in Silver Lake
Blown in fiberglass in Silver Lake typically runs $1,500 to $2,800 for a standard attic application, depending on target R-value and access difficulty.
How we do it
We load Owens Corning or Johns Manville loose-fill fiberglass into the hopper and blow it to the specified depth, using rakes and depth markers to verify even coverage across every bay.
What Blown In Insulation Costs in Silver Lake
| Item | Typical range in Silver Lake |
|---|---|
| Blown in attic insulation | $1,800 – $3,200 |
| Blown in cellulose (attic or walls) | $2,200 – $4,000 |
| Blown in fiberglass (attic) | $1,500 – $2,800 |
Is blown in insulation worth it in Silver Lake’s climate?
Yes. Silver Lake’s cooling season runs six months or more, and an uninsulated attic radiates heat into living space all day. Adding blown-in insulation cuts that radiant transfer measurably, which shows up on your DWP bill almost immediately. Call (833) 390-7079 for an exact quote.
Can you access attics and walls on Silver Lake’s hillside lots?
Usually, yes. We design the access plan around the property. Many stair-street homes have alley-side hatches or roof vents we can feed hoses through without ladder access from the street. We’ll confirm access before quoting. Call (833) 390-7079 and we’ll walk through it together.
Brands We Service in Silver Lake
We carry and install products from GreenFiber, Owens Corning, Johns Manville, and Knauf, among others. Because we stock eight manufacturer lines, we can match the material to the specific cavity and climate conditions in your Silver Lake home rather than defaulting to a single product. See our brands for the full lineup. Since we keep common materials staged locally for Silver Lake jobs, most standard installations go in within a week of the quote.

Most insulation retrofits in Silver Lake fall under standard building maintenance and don’t require permits. Wall dense-packing through exterior stucco may trigger a patching inspection under some conditions. We’ll tell you upfront if your specific property needs anything formal.
Yes, with a caveat. Some cavity walls with active knob-and-tube wiring shouldn’t be dense-packed without electrical work first, because insulation can trap heat around the old conductors. We identify this during the assessment and coordinate with a licensed electrician if needed.
If your Silver Lake home is hot upstairs, drafty in winter, or simply uncomfortable in rooms you use every day, call Airtight Insulation Co at (833) 390-7079 for a free estimate.

What Silver Lake 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."
— Claudia Morales"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."
— Simone Grant"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."
