Insulation Company in Sunland, CA
We lead with blown in insulation in Sunland because the housing stock here demands it. Most homes in Sunland were built between the 1940s and 1960s, and their attics typically hold a thin, settled layer of old rock wool that does almost nothing against foothill heat. When summer pushes 100°F and the southern sun hits those low-pitch roofs all day, attic temperatures can pass 140°F. That heat doesn’t stay in the attic. It radiates down into bedrooms and living rooms, and the air conditioner runs constantly trying to fight it. Blown in insulation, installed to modern R-value depths, is usually the fastest and most cost-effective fix. Call (877) 265-5712 for a free estimate.
Why Sunland Homes Are Different
Sunland sits in the northeast San Fernando Valley at the foot of the Verdugo Mountains. The streets north of Foothill Blvd climb into the foothills, and many homes there face full southern exposure with no shade trees. Those attics get punished. We regularly see attic temperatures exceed 150°F in July and August. Older blown in insulation settles faster under that kind of heat, losing R-value year after year until it’s doing very little. The homes themselves are mostly single-story ranch and traditional tract builds with original 2×4 rafters and low-pitch roofs. Those attic spaces were never designed for modern insulation depths, which means getting to R-38 or R-49 requires working carefully around tight corners and shallow eaves.
Wiring is another Sunland-specific factor. A significant number of these older homes still have knob-and-tube or early Romex electrical. Insulation can’t just be blown over that wiring without attention to clearance and heat dissipation. We check first, then plan the installation around it. Winters here are mild but nights can dip near freezing, so the same homes that bake in summer also lose heat in winter. That wide temperature swing is why we look at the whole thermal picture in Sunland, not just the attic floor.
Our Main Sunland Services
Most Sunland homeowners call us about two things: the attic above them that’s cooking the house, and the air leaks that blow in insulation alone won’t stop. Both deserve a clear explanation.
Attic Insulation in Sunland
Attic insulation in Sunland is the highest-impact upgrade for comfort and cooling bills. The job usually involves air sealing the attic floor first, then installing or topping up insulation to R-38 or R-49. In older Sunland tract homes, that often means removing or working around ancient rock wool, checking for knob-and-tube wiring, and making sure soffit vents stay clear. We carry fiberglass batts from Owens Corning and CertainTeed, plus blown in options, so the material matches the attic’s shape and the roof’s pitch. Every home’s attic is different here, particularly in the foothill streets where the sun hits hardest. Attic Insulation in Sunland
Spray Foam Insulation in Sunland
Spray foam insulation in Sunland is the right call for difficult rooflines, cathedral ceilings, and homeowners who want air sealing and insulation in one pass. Closed-cell foam from Demilec adds structural rigidity and a vapor barrier, which matters in low-pitch attic conversions. Open-cell foam from Icynene air-seals surprisingly well and suits Sunland’s dry heat. The foothill homes with full southern exposure and no shade trees often see the biggest difference from foam, because it stops both radiant heat and air movement at the roof deck rather than only at the attic floor. It’s a bigger investment, and for most Sunland tract homes it’s not always necessary. We’ll tell you straight. Spray Foam Insulation in Sunland

Blown In Insulation in Sunland
Blown in insulation is the most common request we get from Sunland homeowners, and frankly it’s the right answer for most 1940s-1960s tract homes here. These attics often have a thin layer of original rock wool that’s settled, compressed, and effectively useless. Blowing in fresh cellulose or fiberglass to R-38 or R-49 restores the thermal barrier quickly, without tearing out drywall or rebuilding the attic. It’s the fastest way to stop that 140°F attic heat from pressing down into your living space. For the full scope of what we do, see Blown In Insulation.
Cellulose Insulation
Signs you need it
Your attic insulation looks thin, dusty, and settled below the tops of the ceiling joists, and upstairs rooms run 8-10°F hotter than the rest of the house in summer.
What it costs in Sunland
Blown in cellulose in Sunland typically runs $900-$1,800 for a standard 1,200-1,800 sq ft ranch home depending on existing insulation depth and access.
How we do it
We air-seal the attic floor penetrations first, then blow GreenFiber cellulose to the target R-value using a hose and calibrated machine, keeping it off the soffit vents and away from any knob-and-tube wiring.
Blown In Attic Insulation
Signs you need it
Your cooling bills climb every summer, the HVAC runs nonstop on 95°F+ afternoons, and the ceiling feels warm to the touch when you’re up near it.
What it costs in Sunland
Blown in attic insulation in Sunland ranges from $1,200-$2,200 for a full attic top-up to R-38, with the higher end covering deep attics or homes with difficult access.
How we do it
We remove or assess the old insulation where needed, seal top plates and penetrations, then blow fiberglass or cellulose evenly across the attic floor to the specified depth and R-value.
Blown In Cellulose Insulation
Signs you need it
You see gaps, bare spots, or wind-washed areas in the attic where insulation has thinned out, or you want a denser, more air-resistant fill than loose fiberglass.
What it costs in Sunland
Blown in cellulose in Sunland typically costs $900-$1,800 for a whole-attic installation, the same range as standard blown in work here.
How we do it
We use GreenFiber recycled cellulose, blown to the correct pounds-per-square-foot density for the R-value we’re targeting, which holds up better than loose fiberglass against settling in Sunland’s hot attics.
Blown In Fiberglass Insulation
Signs you need it
The attic has older fiberglass batts that have compressed and sagged, and you want a fast, clean fill that doesn’t require removing what’s there.
What it costs in Sunland
Blown in fiberglass in Sunland runs $1,000-$2,000 depending on attic size and the depth needed to reach the target R-value.
How we do it
We blow loose-fill Johns Manville fiberglass over and around existing batts where safe, filling gaps and building to the depth required for the attic’s R-value goal.
Loose Fill Insulation
Signs you need it
The attic has hard-to-reach corners, shallow eaves, and irregular joist spacing where batts don’t fit cleanly and leave gaps.
What it costs in Sunland
Loose fill insulation in Sunland runs $1,000-$2,200 for a full attic, with pricing set by the material, depth, and whether old insulation needs removal first.
How we do it
We blow loose fill into all the irregular spaces, around framing and wiring, until the entire attic floor is at a consistent depth with no gaps or thin spots.
What Blown In Insulation Costs in Sunland
| Item | Typical range in Sunland |
|---|---|
| Blown in insulation (full attic, standard ranch) | $900-$1,800 |
| Blown in attic insulation (full top-up to R-38) | $1,200-$2,200 |
| Loose fill / problem attics (irregular access) | $1,000-$2,200 |
In Sunland, the biggest price drivers are attic size, how much old insulation has to be pulled out, and how difficult the access is. Foothill-facing homes with low-pitch roofs and shallow eaves often take more labor per square foot than a flat, open attic on the valley floor. We give you an upfront, line-item price before we begin, and that price doesn’t change unless you change the scope.
Is blown in insulation worth it in Sunland’s heat?
Yes. Blown in insulation at R-38 or R-49 cuts attic heat transfer dramatically, which lowers cooling bills and makes upstairs rooms noticeably more comfortable. In Sunland’s 100°F summers, that’s the single highest-impact insulation upgrade. Call (877) 265-5712 for a free estimate.
Can you blow insulation over the old insulation in my Sunland attic?
Usually, yes. We can blow cellulose or fiberglass over settled rock wool or old batts as long as the existing material is dry and there’s no knob-and-tube wiring that needs clearance. We check first. Call (877) 265-5712 to schedule an attic inspection.
Brands We Service in Sunland
We carry Demilec and Icynene spray foam, GreenFiber recycled cellulose, and Owens Corning and Johns Manville fiberglass. That means the material recommendation is driven by your home’s thermal needs, not by whichever brand we happen to stock. Our brands are selected for performance in Sunland’s specific climate.

Prices in Sunland move up when the attic is shallow with 2×4 rafters, when knob-and-tube wiring needs clearance work, or when old insulation has to be removed before the new material goes in. Foothill homes with full southern exposure and hard-to-reach attic spaces land on the higher end. We price every job upfront before any work starts, so you know exactly what the insulation will cost before we open a single bag.

Most Sunland calls get scheduled within 2 to 3 days, and we can often accommodate next-day visits during the off-peak season. Summer fills up quickly because attics are hottest then. Call (877) 265-5712 and we’ll get you on the schedule.
For standard attic insulation and blown in work, no permit is typically required in Sunland. If the project involves structural changes like a roof deck spray foam application that modifies the attic envelope, permit requirements may apply. We handle that determination and the paperwork if needed.
We’re an insulation-only contractor, so every estimate and every crew hour is focused on one thing. We carry eight nationally recognized brands, but we don’t push all of them on every home. We look at the attic, the roof orientation, the wiring, and the existing insulation, then recommend the material that actually fits. That’s the whole job.

— Ryan Rhodes"Spray foam in the rim joists in the basement. The cold floors above them are gone."
— Bethany Ziegler"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."
