We work in Van Nuys every week. We know the low-pitched roofs, the tight attic hatches, the knob-and-tube surprises. We plan for them before we arrive, not after.
Why Even Air Insulation Is Van Nuys’s Preferred Attic Insulation Company
Homeowners across 91401, 91405, and 91406 keep calling us back because we explain what their attic actually needs and why. No scare tactics, no single-product pitch. Nelson Quirarte built Even Air Insulation around one idea: match the material to the problem, not to what’s sitting in the truck.
We run three installation crews trained across attic insulation, spray foam, and blown-in methods. That matters in Van Nuys, where the right answer for a 1950s tract home with knob-and-tube wiring is often different from what a newer addition needs. We’ll tell you when cellulose makes sense, when open-cell foam does the job, and when a simple top-up is enough. Most contractors only sell you the one system they install. We carry eight brands so we don’t have to force a bad fit.
Our estimators respond to Van Nuys calls within one business day. Scheduling usually lands within three to five days for standard jobs. We keep fiberglass batts, cellulose, and foam rigs stocked and staged in Koreatown, so a run to Van Nuys doesn’t mean waiting on a supplier.
Insulation Contractors in Van Nuys
Insulation contractors in Van Nuys do far more than lay batts. A proper job starts with inspecting what’s already up there, identifying air leaks, checking for old wiring, and then choosing a material that will hold up under 150°F attic heat. Homeowners should consider a full attic insulation replacement when original batts have compressed, when rodent activity has contaminated the existing material, or when rooms directly under the attic won’t hold temperature. A full removal and re-insulation in Van Nuys runs $1,800 to $4,200 depending on attic size and access.
Attic Insulation Top-Up
If your existing insulation is dry, clean, and simply below modern R-value, a top-up is the most cost-effective move. We blow loose-fill fiberglass or cellulose over the existing layer after confirming the attic is venting properly. Expect to pay $650 to $1,400 in Van Nuys for a standard 1,200-square-foot attic top-up.
Attic Batt Insulation
For attics with open joist bays and easy access, batt insulation gives you a clean, predictable install. We stock Owens Corning and Johns Manville batts in R-30 and R-38. Batt work in Van Nuys runs $1,200 to $2,600 on average, with the low-clearance attics common to 1950s tract homes sometimes adding labor time.
Attic Ventilation in Van Nuys
Attic ventilation in Van Nuys isn’t an add-on. When outdoor temperatures push past 100°F and attic air hits 150°F or more, a poorly vented attic will cook your insulation and force your air conditioner to fight a losing battle. Homeowners should request a ventilation assessment when adding insulation, when upstairs rooms run 10 to 15 degrees hotter than the rest of the house, or when they see peeling paint or warped roof decking. A typical baffle and venting upgrade in Van Nuys runs $400 to $1,100 depending on the number of rafter bays and whether ridge or gable vents need to be added.
Baffles and Soffit Prep
Low-pitched Van Nuys roofs often have soffits that were never set up for airflow. We install baffles in each rafter bay to keep blown insulation from blocking the soffit vents. It’s cheap insurance, and it usually solves the “I insulated but my upstairs still won’t cool” problem.
Ridge Vent and Gable Retrofit
Older tract homes often rely on one tired gable vent. We trim and add ridge vents where roof pitch allows, or upgrade gable venting with powered fans in stubborn cases. The goal is always the same: move 150°F air out so the insulation can actually do its job.
Trusted Brands We Service in Van Nuys
We stock GreenFiber cellulose for dense-pack and blown-in work, Demilec open-cell and closed-cell foam for air-sealing and structural applications, and Owens Corning fiberglass for batts and loose-fill. Because we keep material staged in Koreatown, Van Nuys customers rarely wait more than a few days for a scheduled install, even on larger retrofit jobs. We’ll walk you through why one brand fits your attic better than another before we quote anything.
Common Attic Insulation Problems We See in Van Nuys Homes
- Compressed original batts from 150°F heat. The 1950s fiberglass in these tract homes has been baked for decades. It flattens to under an inch and loses most of its R-value, leaving the ceiling plane effectively bare. We remove and replace it rather than topping it up, because topping up over dead insulation doesn’t fix the problem.
- Rodent contamination in low-clearance attics. Rats and mice love the dusty, warm spaces above Van Nuys ceilings. Their droppings and nesting material mat the insulation and create a health hazard. We clear it, sanitize what can’t be removed, and seal entry points before installing anything new.
- Knob-and-tube wiring under old insulation. Many pre-1960 Van Nuys homes still have active knob-and-tube circuits buried under batts. Blowing insulation directly over live knob-and-tube is a fire risk and a code violation. We identify it during inspection and work with your electrician before insulating.
- Blocked or missing soffit vents. Tract homes built tight to the roofline often have soffits that were never vented. Without baffles and airflow, blown insulation blocks what little ventilation existed, and moisture starts building up. We address venting before we add insulation, not after.

FAQs About Attic Insulation in Van Nuys
The original fiberglass batts in 1950s Van Nuys tract homes have been sitting in 150°F attic heat for over 60 years, which causes the fibers to break down and compress to a fraction of their original thickness. A batt that started at R-19 may now be performing at R-5 or less. Add decades of dust, rodent traffic, and settling, and you get a mat that looks like it’s almost gone. Replacement is the fix, not a top-up. Call (855) 362-0195 and we’ll show you what’s actually up there.
No, not safely. Blown or batt insulation cannot be installed directly over live knob-and-tube wiring because it creates a fire hazard and violates electrical code. We’ll identify the wiring during our inspection and coordinate with a licensed electrician to address it first. Once the wiring is updated or decommissioned, we can proceed with the insulation work.
R-38 to R-49 is the right range for Van Nuys attics. The Department of Energy’s climate zone map puts the San Fernando Valley in a high cooling-load zone, and the 150°F attic temperatures we see here make R-49 the better target for most homes. We typically install R-49 when we do full replacements, and we’ll explain what that means for your specific attic.
We remove the contaminated insulation, bag it on site, and dispose of it properly. Then we sanitize the attic floor, seal the entry points the rodents used, and install new insulation. It’s a full service we do regularly in Van Nuys, especially in the older tracts near Victory Boulevard and Sepulveda where roof-rat pressure is high.
Baffles in each rafter bay are the priority for low-clearance Van Nuys attics, because they keep blown insulation from blocking the soffit vents. Where the roof pitch allows, a ridge vent is the next step. In attics with almost no headroom, we may find that a powered gable fan is the only realistic way to move enough air. We’ll assess it on site and only recommend what your roof can actually support.
