Insulation Company in Silver Lake, CA
Most homeowners call us when their second-floor rooms are baking in August or their energy bill has doubled in the last five years. Blown In Insulation is the service we recommend most often in Silver Lake, because the neighborhood’s 1920s and 1930s bungalows were built before insulation was standard – and the ones that do have some are almost always under-insulated for a climate where the attic can hit 140°F on a July afternoon. We’re Orange County Insulation, an insulation-only contractor that has served Silver Lake since 2013. Call (877) 680-3557 if you want a straight answer about what’s actually going on inside your walls and attic.
Why Silver Lake Homes Are Different
Silver Lake’s housing stock was built for a different era. The Spanish Colonial and California bungalow homes that line the streets around the reservoir date mostly from the 1920s through the 1940s, and many were constructed with lath-and-plaster walls and open attic cavities that were never intended to hold insulation. The original assumption was simple: coastal California, mild winters, open the windows. That assumption falls apart quickly when the summer sun hits a stucco wall for six hours straight, and the upstairs bedrooms turn into ovens by 4 p.m.
The hillside lots add another layer. Homes on the slopes above Sunset Boulevard and around the Silver Lake Reservoir catch the afternoon sun at a steeper angle than flat-land houses, which means the radiant heat load on the roof and west-facing walls is more intense. We regularly see attic cavities in Silver Lake where the original framing has no ridge vents and no eave vents at all – the roof was designed to breathe passively, and it simply can’t keep up with the heat that a 90026 summer brings. When you add blown-in insulation to a vent-starved attic, you can actually trap the heat inside and push shingle temperatures past where most manufacturers void their warranties. That’s why the ventilation question comes first on almost every Silver Lake job we quote.
Our Main Silver Lake Services
Two services account for most of the calls we get from Silver Lake homeowners, and each one solves a different version of the same problem.
Attic Insulation in Silver Lake
Attic work in Silver Lake almost always starts with an inspection of the existing ventilation, because so many of these older homes were built without ridge or eave vents. If the airflow is wrong, no amount of insulation will fix a hot second floor. We assess what’s already in the attic, check for knob-and-tube wiring or lath-and-plaster issues that need to be worked around, and then match the insulation type to the roof design. Full details are on our Attic Insulation in Silver Lake page.
Spray Foam Insulation in Silver Lake
For Silver Lake homes with limited attic clearance, vaulted ceilings, or attached garages that share a wall with the living space, spray foam is often the cleanest answer. It creates an air seal as well as an insulation layer, which matters on hillside lots where wind-driven air leaks through old framing. We install both open-cell and closed-cell foam depending on the moisture profile and the budget. For specs and project photos, see Spray Foam Insulation in Silver Lake.

Blown In Insulation in Silver Lake
Blown-in insulation is the workhorse solution for older Silver Lake homes because it’s the only practical way to add meaningful R-value to an existing wall or attic without opening up the plaster. In the 90026 ZIP code, we’re usually working inside attics that reach 140°F-plus in summer, where the original builders left nothing but a gap between the ceiling and the roof deck – and where a one-size-fits-all fiberglass batt install would leave the edges of the ceiling joists uninsulated. Blown-in material fills those gaps, settles into the odd framing of a 1927 bungalow, and makes the whole room below measurably cooler by August. It’s the service we recommend first for comfort complaints in Silver Lake, and you can read more detail on our Blown In Insulation service page.
Cellulose Insulation
Signs you need it
Your attic floor has thin or bare patches of old insulation, or your second-floor rooms are noticeably warmer than the first floor by mid-afternoon despite the AC running.
What it costs in Silver Lake
Cellulose blown into an existing 1,000 sq ft attic in Silver Lake typically runs $2,300 to $4,600 depending on the depth and whether old material must be removed first.
How we do it
We dense-pack or loose-fill GreenFiber cellulose through small access holes, building to the target R-value while working carefully around any knob-and-tube wiring present in the attic.
Blown In Attic Insulation
Signs you need it
Your energy bills rise every summer, your AC runs constantly on hot days, or the ceiling feels warm to the touch from below.
What it costs in Silver Lake
Blown-in attic insulation for a typical 90026 bungalow runs $1,800 to $3,800, with the final number depending on the existing depth and whether ventilation upgrades are included.
How we do it
We seal the attic bypasses first, check the ventilation ratio, then blow loose-fill fiberglass or cellulose to the building code depth for the Silver Lake climate zone.
Blown In Cellulose Insulation
Signs you need it
Your home retains heat late into the evening hours after the sun goes down, which tells us the thermal mass of the house is absorbing more than it should.
What it costs in Silver Lake
Blown-in cellulose in Silver Lake typically costs $1.10 to $1.50 per square foot installed, with most whole-attic projects landing between $2,400 and $3,900.
How we do it
We run the GreenFiber cellulose through a blower hose up to the attic, distribute it evenly across the ceiling plane, and leave a consistent depth marked with depth gauges.
Loose Fill Insulation
Signs you need it
There are gaps, bald spots, or uneven depth in the existing attic insulation, or you’ve had rodent activity that flattened and compressed what was there.
What it costs in Silver Lake
Loose fill for a small attic over a single-car garage in Silver Lake usually runs $900 to $1,800 total, including cleanup and disposal of any old material we remove.
How we do it
We evaluate the existing material for depth and condition, remove anything damaged or compressed, then blow new loose fill to the agreed R-value with an even spread.
What Blown In Insulation Costs in Silver Lake
| Item | Typical range in Silver Lake |
|---|---|
| Blown-in attic insulation, 1,000 sq ft | $1,800 – $3,800 |
| Cellulose wall retrofit, per sq ft | $1.10 – $1.50 |

Can blown-in insulation be added to walls in a Silver Lake bungalow without gutting them?
Yes, in most cases. We drill small access holes through the stucco or siding, blow the material into the stud bay, and patch the holes to match. The process works well with lath-and-plaster walls as long as there’s no active moisture problem. Call us at (877) 680-3557 and we’ll give you an honest read on your particular house.
Does blown-in insulation work as well in a cooling climate as it does in a heating climate?
Yes, it works differently but just as effectively. In Silver Lake’s hot summers, blown-in cellulose and fiberglass slow the radiant heat transfer from the attic down into the living space. You’ll feel the difference most in the late afternoon. Call us at (877) 680-3557 and we’ll explain what depth your home actually needs.

We give you a line-item quote before any work begins, so the number on the proposal is the number on the invoice.
