We know North Hills attics. They’re not the clean, empty spaces a foam crew sees on a new build in Valencia. They’re 1960s vented attics with attic-mounted furnaces, flex-duct sprawl, and original batts that have been crushed into paper for four decades. That changes how you foam them. We work around it every week.

Why Cozy Insulation Co Is North Hills’s Preferred Spray Foam Insulation Company

North Hills homeowners keep calling us because we treat their homes as retrofits, not fresh canvases. The teams that blanket the valley with generic spray-and-go quotes rarely account for what a 1962 ranch off Plummer Street actually looks like above the ceiling line. We do. Mike Callahan built our process around the specific mess of vented attics, attic furnaces, and settled batts that define this housing stock.

We’re not the cheapest bid on Spray Foam Insulation in North Hills, and we don’t try to be. We bring our own Spray Foam Insulation crew, never a sub, and we carry Icynene and Demilec systems that most local contractors don’t stock. That matters when your attic furnace is still connected and your ductwork crosses half the deck. We foam around it properly instead of asking you to rip everything out first. From Northridge to Van Nuys, the feedback is the same: the quote was detailed, the crew showed up, and the upstairs rooms finally hold temperature. Call (855) 382-3925 for a free estimate and we’ll measure your attic the same week.

Open Cell Spray Foam in North Hills

Open Cell Spray Foam is the workhorse for North Hills attic retrofits because it expands into the irregular cavities, plumbing penetrations, and framing gaps that blanket these 1950s and 60s ranch ceilings. At roughly $2.80 to $4.50 per board foot installed, it’s the more cost-effective foam option for conditioned attic builds. Open cell is not a structural barrier or a vapor seal; it’s an air and thermal buffer that fills the oddly-shaped spaces older valley homes are full of.

Attic Deck and Ceiling Line

On a typical North Hills ranch, we spray open-cell Icynene across the underside of the roof deck, turning the unconditioned vented attic into a sealed, conditioned space. The payoff is immediate: that 140°F+ attic air stops radiating through your hallway ceiling. Bedrooms on the west side of the house stop overheating by late afternoon because the foam is intercepting the heat where it enters.

Air Sealing First

Open cell foam in North Hills only works if the top plates, wire chases, and plumbing penetrations are sealed first. We find open bypasses behind original drywall on nearly every job in 91343. If you don’t seal those, hot attic air simply routes around the foam. We seal with the same two-part foam system, then spray the deck.

Spray Foam Insulation Contractors in North Hills

Spray Foam Insulation Contractors in North Hills who know the local housing stock will start by looking at your attic furnace, not just your square footage. Cozy Insulation Co handles the whole job with our own crew: we evaluate the existing ductwork, map where the crushed batts are, seal the bypasses, and then spray. A full open-cell attic retrofit on a 1,600 square foot ranch typically runs $5,500 to $9,200 depending on deck area and how much old material must come out.

Working Around Attic Furnaces

Most North Hills homes from the 1960s have the furnace sitting in the attic, not a basement or closet. That furnace and its flex-duct runs create blind spots for foam coverage if the crew doesn’t plan around them. We foam the deck in sections, working behind and under duct runs so the coverage is continuous. A crew that ignores that leaves bare hot spots the spray pattern never addressed.

Whole-House Fan and Attic Fan Cutouts

Many Valley ranches got attic fans or whole-house fans retrofitted in the 1980s and 90s. Those fans cut through the ceiling plane and pull conditioned air straight out of the living space. When we foam, we either seal those units properly or build around them so they don’t become gaping holes in your new thermal envelope. This is the kind of detail that separates a real retrofit crew from a spray-and-leave contractor.

Trusted Brands We Service in North Hills

We install and service Icynene and Demilec open- and closed-cell spray foam systems on North Hills homes, along with Owens Corning and Johns Manville batt products when a hybrid approach makes more sense. Because we keep Icynene open-cell and Demilec closed-cell in stock for 91343 and 91393 jobs, we can usually start a North Hills project the same week we measure it. If your existing foam was installed by another company and has gaps, shrinkage, or separation at the deck, we’ll evaluate it and tell you straight what needs redoing and what doesn’t.

Common Spray Foam Insulation Problems We See in North Hills Homes

• Crushed batts under attic furnace ductwork. The original fiberglass in these 1960s ranches gets flattened into a paper-thin mat under decades of flex-duct weight. When we foam the deck, that old material often needs pulling first so the foam has clean access to the ceiling line.
• Unsealed top plates leaking attic heat into hallways. Behind original drywall, the gap where wall framing meets the ceiling is almost never sealed on North Hills homes built before 1980. Foaming the deck without sealing those bypasses is like putting a lid on a pot with no bottom. We seal first, every time.
• Bare hot spots from uneven prior foam coverage. We regularly see attics where a previous crew sprayed around visible joist bays but skipped the areas behind duct runs, over the furnace platform, and at the eaves. Those bare spots are exactly where the 140°F+ valley heat gets in.
• Whole-house fans cutting through new foam. Older ranch retrofits often have an attic fan or whole-house fan that was cut in decades ago. Left unsealed, it becomes a conditioned-air leak that negates much of the foam’s benefit. We see it on Plummer Street, on Nordhoff, on Septo, all over 91343.
