Insulation Company in Silver Lake, CA
Blown in insulation is the workhorse solution for Silver Lake’s older homes, and it’s where most of our local jobs start. The neighborhood’s 1920s and 1930s Spanish bungalows and hillside midcenturies were built when insulation was an afterthought, if it was considered at all. That means most Silver Lake homeowners aren’t topping up existing insulation, they’re retrofitting a thermal envelope from scratch. We address that with dense-pack cellulose and fiberglass blown behind original lath-and-plaster walls, plus attic work tuned for Southern California’s heat-driven load. If you’re researching insulation for a Silver Lake home, call (877) 352-4780 for a free estimate.
Why Silver Lake Homes Are Different
Silver Lake sits in a basin sheltered by the Santa Monica Mountains, which shapes the insulation problem in a specific way. The real load here is attic heat gain and sun beating on west- and south-facing walls, not deep-winter cold. A 1926 Spanish bungalow off Hyperion Avenue with zero wall insulation will bake in August, and so will a 1964 post-and-beam on a hillside with a flat roof exposed to afternoon sun. The same block can have a flat-roof midcentury needing roof-deck insulation next to a 1920s fourplex with original lath-and-plaster walls needing dense-pack treatment. That lack of uniformity is the local pattern, and it means we diagnose each house individually rather than applying a one-size-fits-all spec.
Many Silver Lake walls are original plaster over wood lath with no cavity insulation at all. The cavity is typically shallow, around 3.5 inches, and the construction is not forgiving of guesswork. Dense-pack blown in insulation is the standard approach here because it fills the irregular cavities without tearing out plaster. Crawlspaces and vented attics on the hillside lots add another layer, as afternoon radiant heat penetrates those spaces and drives heat upward into living areas. We plan the job around that heat path, not around a Midwest-style winterization checklist.
Our Main Silver Lake Services
Most Silver Lake homeowners call us about two services first: attic insulation and spray foam. Here’s how each applies to the neighborhood’s housing stock.
Attic Insulation in Silver Lake
Silver Lake attics are rarely simple. Spanish bungalows from the 1920s often have low-slope or nearly flat ceilings with minimal access, while hillside midcenturies combine vaulted ceilings with vented attic spaces that trap heat from afternoon sun. Attic insulation in Silver Lake means assessing whether the home needs batt replacement, blown in coverage, or a hybrid approach for irregular framing. We pull from eight manufacturer brands including Owens Corning and CertainTeed, so the material matches the structure rather than the other way around. For the full scope of what we do in Silver Lake attics, see Attic Insulation in Silver Lake.

Spray Foam Insulation in Silver Lake
Spray foam earns its place in Silver Lake’s hillside homes and flat-roof buildings. Open-cell foam from Icynene works well for interior cavities where moisture permeability matters, while closed-cell Demilec adds structural rigidity and a vapor barrier for roof decks and exposed floor systems. The material choice depends on whether we’re sealing a vented attic, insulating under a flat roof, or air-sealing a crawlspace above a slope. We carry both open- and closed-cell systems and install whichever the building science calls for. Details are on the Spray Foam Insulation in Silver Lake page.

Blown In Insulation in Silver Lake
Blown in insulation is the most common retrofit method we install in Silver Lake because it’s the only practical way to insulate walls without opening them. Homes built here between 1920 and 1970 typically have empty wall cavities and uninsulated attics, and blown in material, whether cellulose or fiberglass, fills those irregular spaces completely. For Silver Lake homeowners dealing with hot rooms, high cooling bills, and walls that radiate heat after sundown, blown in insulation addresses the root cause. You can read more about the method on our Blown In Insulation hub page.
Blown In Attic Insulation
Signs you need it
Rooms directly under the attic are noticeably hotter than the rest of the house on summer afternoons, and the air conditioner runs longer than it should without hitting the set temperature.
What it costs in Silver Lake
Blown in attic insulation in Silver Lake typically runs $1,700 to $3,400 for a standard attic, depending on square footage, existing insulation depth, and access conditions.
How we do it
We air-seal bypasses around penetrations, install baffles at the eaves, and blow loose fill to the target R-value across the attic floor, working around any existing framing and ductwork.
Blown In Cellulose Insulation
Signs you need it
Interior walls feel warm to the touch in summer or cold in winter, and you hear too much noise from outside or from adjacent units.
What it costs in Silver Lake
Dense-pack cellulose for existing walls in Silver Lake typically costs $1.25 to $1.90 per square foot of wall area, including drilling, filling, and patching access holes.
How we do it
We drill small access holes through the plaster or drywall at each stud bay, dense-pack cellulose to the correct density using the GreenFiber system, then patch and texture the holes to match.
Blown In Fiberglass Insulation
Signs you need it
Your attic has old, settled insulation that’s lost its loft, or you’re remodeling and need an economical open-blow material with good coverage per bag.
What it costs in Silver Lake
Blown in fiberglass attic work in Silver Lake typically runs $1,100 to $2,500, varying with the target R-value and the number of existing attic obstructions.
How we do it
We remove or top existing material as needed, prep the attic floor for even depth, and blow fiberglass from Johns Manville or Knauf to a consistent, code-compliant depth.
Loose Fill Insulation
Signs you need it
Your attic has uneven insulation depth with bare spots, or you have hard-to-reach areas where batts would leave gaps around framing and wiring.
What it costs in Silver Lake
Loose fill insulation projects in Silver Lake typically range from $1,400 to $3,000, depending on the material chosen and whether old insulation requires removal first.
How we do it
We assess the existing thermal boundary, add or replace loose fill to the specified depth using calibrated blowing equipment, and verify coverage with depth markers throughout the space.

Does blown in insulation work in old plaster walls?
Yes. Silver Lake’s original lath-and-plaster walls are ideal candidates for dense-pack blowing. The material fills the irregular cavity and stays in place without sagging, preserving the plaster finish with only small access holes to patch. Call (877) 352-4780 to have us look at your walls.
How long does blown in insulation take in Silver Lake?
A typical Silver Lake attic takes half a day to a full day. Wall retrofit work on a 1920s bungalow usually takes one to two days, including patching. We schedule around your availability and keep the work area clean. Call (877) 352-4780 for a timeline.
