Attic Insulation in Van Nuys — Same-Day Service, Done Right the First Time

Fast, Reliable Attic Insulation Across Van Nuys

Attic insulation in Van Nuys comes down to one uncomfortable reality: most homes here were built between 1940 and 1955, and their original insulation was never adequate for a San Fernando Valley summer. A typical attic in a Van Nuys bungalow hits 140°F by mid-afternoon in August, and with collapsed rock wool or settled fiberglass offering less than R-5 of resistance, that heat pours straight into your living space. We’re Fontana Insulation, and we’ve spent years retrofitting these exact houses. Call (866) 271-1602 and we’ll tell you honestly whether you need a full removal, a top-up, or a material change. Usually in Van Nuys, it’s a full removal.

Why Fontana Insulation Is Van Nuys’s Preferred Attic Insulation Company

Most insulation companies in the Valley push one product. We don’t. We carry eight brands across fiberglass, mineral wool, spray foam, and cellulose, which means the recommendation you get is based on your attic’s actual condition, not what’s cheapest for us to stock. For Van Nuys’s shallow, low-pitch attics, that usually means blown-in fiberglass or cellulose rather than batts that get compressed and lose R-value. For homeowners who want fire resistance and sound dampening alongside thermal performance, we stock Attic Insulation materials including Rockwool mineral wool, which most local contractors don’t even carry.

Led by Noel Arredondo, our crew works on Van Nuys homes every week. We know the floor plans. We know the knob-and-tube wiring hiding under old batts. We know which tract streets have blown-in rock wool from the 1950s and which got fiberglass retrofits in the 1980s. That local familiarity means we quote accurately and install efficiently. No surprises halfway through the job.

Our approach is material-agnostic. We carry Owens Corning and CertainTeed because they’re the most widely warrantied fiberglass brands in the industry. We carry Icynene and Demilec because open-cell spray foam solves air-sealing problems that blanket material can’t touch. We carry GreenFiber for homeowners who want recycled-content cellulose. The right material for your attic is the one that fits your house, your budget, and your cooling bill goals. Not our inventory.

Attic Insulation Removal in Van Nuys

Attic insulation removal in Van Nuys is the starting point for most of our jobs here, and it’s something other contractors gloss over or skip entirely. In a 1949 bungalow near Van Nuys Boulevard and Kittridge Street, we found the original rock wool collapsed to a 1-inch mat, chewed kraft vapor barrier, and active rodent runs. After removing the debris and re-insulating exposed knob-and-tube wiring, we blew in Owens Corning fiberglass to R-38 and added a radiant barrier, dropping the attic temperature by about 25°F on a 105°F afternoon. That’s what removal-and-retrofit looks like, and it’s the reason a simple blow-over doesn’t work in this housing stock.

Removal means vacuuming out everything down to the drywall or plaster, sanitizing where rodent contamination exists, and giving us a clean thermal boundary to work from. It’s required when insulation is water-damaged, rodent-soiled, or settled below useful R-value. In Van Nuys, that describes a significant portion of homes built before 1960.

When Removal Is Non-Negotiable

If your attic has knob-and-tube wiring, you cannot legally or safely bury it under new insulation. The old cloth-wrapped conductors need to be evaluated, and in many cases re-insulated by a licensed electrician before we blow in anything new. We flag this early in the estimate so you’re not surprised later.

What Removal Costs

Full attic insulation removal in Van Nuys typically runs $1,800 to $3,500 for a standard 900 to 1,200 square foot bungalow attic. Add $300 to $600 for sanitizing if we find significant rodent runs or droppings. The removal itself is the foundation; new blown-in insulation typically runs another $1,500 to $2,800 depending on material and target R-value.

Insulation Contractors in Van Nuys

Insulation contractors in Van Nuys fall into two camps: the ones who blow fiberglass over whatever’s already up there, and the ones who actually assess what’s happening in your attic first. We’re the second kind. Every job starts with a look at what’s up there: material type, depth, settled R-value, air leaks at penetrations, ventilation status, and any wiring or rodent issues. That assessment is free, and it determines everything we recommend.

Because we install three methods in-house, attic insulation, spray foam, and blown-in, we’re not going to sell you on a method that doesn’t fit. If your bungalow has a ventilated attic, blown-in fiberglass or cellulose is usually the best dollar-per-R-value choice. If you have a flat-roof addition or a converted garage, spray foam might be the better call. We do both without subcontracting, which keeps quality in our hands and scheduling on our clock.

What to Expect at the Estimate

We measure the attic, identify the existing material, check for air leaks around can lights and plumbing penetrations, and give you a written quote that separates removal, air-sealing, insulation, and any additional work. No vague numbers. No day-of upsells.

Licensed, Insured, and Local

Fontana Insulation is state-licensed, insured, and bonded. We work in Van Nuys weekly, so we can usually schedule within a few days of your estimate. For urgently hot attics in July and August, we do our best to prioritize Valley jobs because we know what that heat feels like.

Trusted Brands We Service in Van Nuys

We don’t have a brand loyalty problem. We carry CertainTeed fiberglass for its consistent quality and strong warranty program, Rockwool mineral wool because some Van Nuys homeowners want fire resistance and sound dampening that fiberglass can’t match, and Icynene and Demilec spray foam for the air-sealing jobs that blanket insulation can’t solve. Different attics need different materials. By stocking all of them, we can tell you the truth about what your attic needs without pressure. No brand loyalty, just the best fit for your attic.

Common Attic Insulation Problems We See in Van Nuys Homes

• Collapsed original rock wool. In 1940s and 1950s tract homes, the original rock wool has crushed and settled to under R-5, offering almost no resistance to the 140°F+ attic heat that builds over Van Nuys every summer afternoon.
• Rodent runs and chewed vapor barriers. The kraft paper vapor barriers in old attics are a rodent highway. Chewed, soiled, and torn, they create air leaks and contamination that make a simple blow-over both ineffective and unhealthy.
• Knob-and-tube wiring under old insulation. Many Van Nuys bungalows still have active knob-and-tube circuits in the attic. Burying them in new insulation is a fire hazard and a code violation; the wiring must be addressed first.
• Shallow, low-pitch attics that restrict airflow. The low-slope roofs common across Van Nuys mean less attic volume and less room for ventilation. New insulation compresses easily during installation, which cuts its rated R-value if we’re not careful about depth and baffles.
