Fast, Reliable Attic Insulation Across North Hollywood
Attic insulation in North Hollywood is a retrofit job in most cases, because the bulk of our housing stock went up before 1965 and was never insulated to handle San Fernando Valley heat. We work across 91615, 91616, 91618, and 91601, from the NoHo Arts District to the neighborhoods off Burbank Boulevard and Coldwater Canyon. Call (833) 390-3099 and we’ll schedule an attic assessment quickly, usually within a few days. We know the difference between a 1940s tract attic and a dingbat conversion, and we plan the job around what’s actually behind the access hatch.

Why Fountain Valley Insulation Is North Hollywood’s Preferred Attic Insulation Company
Fountain Valley Insulation carries a lineup most North Hollywood contractors can’t match. We install blown-in fiberglass, attic batts, and spray foam, and we work with eight manufacturer brands including Owens Corning, Johns Manville, and Knauf. That matters here because Valley heat demands higher R-values than coastal LA, and the right material depends on the attic’s framing, access, and whether you’re dealing with an old tract home or an apartment conversion. Nate Calloway built this company around matching the material to the home, not forcing a single product on every job.
Access is a constant issue in North Hollywood. Many streets near the Arts District are dense with parked cars, alley-loaded garages, and apartment buildings where the attic hatch is in a closet ceiling. Our crews are used to that. We stage equipment from the street or alley, protect hallways and carpet with drop cloths, and work around the single-family homes along Chandler Boulevard and the newer townhome infill near the Red Line station. The result is a clean job with minimal disruption, done by people who understand North Hollywood’s specific housing stock.
Attic Cleaning Services in North Hollywood
Attic Cleaning Services in North Hollywood typically involve removing old settled insulation, rodent nesting material, decades of dust from Santa Ana wind events, and debris left behind by previous owners or tradespeople. Homes in 91615 and 91616 that date from the 1940s and 1950s often have attic floors that haven’t been touched since construction. A cleanup usually runs $800 to $1,500 for a typical 1,000-square-foot attic, and we remove the waste from the property. You’ll want this done before any insulation top-up or replacement, or as a standalone job if you’ve noticed odors, pests, or simply can’t remember the last time anyone looked up there.
What Attic Cleaning Involves
We start by removing the old insulation with a high-powered vacuum system that reaches the far corners of low-slope Valley roofs. We then sweep and sanitize the attic floor, check for any wiring issues, and leave the space ready for new insulation. For North Hollywood’s older attics, it’s common to find settled rock-wool or blown fiberglass down to 2 or 3 inches, sometimes with rodent damage mixed in.

When North Hollywood Homeowners Need It
If you smell musty air when the AC cycles, see droppings in the attic, or notice insulation spilling from a ceiling hatch, it’s time for a cleaning. Dingbat apartment conversions and older duplexes near the Arts District tend to accumulate more crud because the party-line walls share air with neighboring units. A cleaning plus air sealing can drop your cooling load noticeably during a Valley heat wave.

Attic Mold Removal in North Hollywood
Attic Mold Removal in North Hollywood is a service we handle frequently because Valley attics trap heat and any moisture that finds its way up from bathrooms, kitchens, or unvented laundry rooms. Mold removal typically runs $1,200 to $2,800 depending on the affected square footage and whether the sheathing needs treatment. We inspect the attic, identify the moisture source, remove moldy insulation, treat the framing, and then air-seal and re-insulate so the problem doesn’t return. If you’ve got dark staining on attic rafters or a persistent musty smell in the upstairs bedrooms, this is the fix.
Mold Sources We See in North Hollywood Attics
The pattern is consistent. Bathroom exhaust fans venting directly into the attic instead of through the roof, combined with the Valley’s high summer heat, create the perfect conditions for mold growth on South-facing sheathing. Older 1950s tract homes often have unvented laundry rooms that push warm, humid air up through ceiling penetrations. We address the root cause first, then remove the mold.
How We Remove It
We use an EPA-registered antimicrobial treatment on the framing after removing contaminated insulation. We don’t just spray over the mold and walk away. Once the attic is dry and sealed, we install new insulation matched to the space, which seals off the surface and reduces the chance of recurrence. This is not a DIY job; mold remediation requires respirators, proper containment, and a plan for controlling moisture.

Trusted Brands We Service in North Hollywood
We’re a multi-brand shop, which means we don’t have to sell you one product. We install Owens Corning, Johns Manville, Knauf, Rockwool, and CertainTeed for blown-in and batt work. For spray foam, we use Icynene and Demilec, two of the most respected names in the category. GreenFiber is available for homeowners who want recycled-content insulation. Because we stock materials for North Hollywood jobs specifically, we can often start a retrofit within days rather than waiting on a distributor in the Valley.
Common Attic Insulation Problems We See in North Hollywood Homes
- Settled rock-wool or blown fiberglass at 2 to 3 inches. Most 1940s and 1950s tract homes in 91601 and 91605 were insulated to R-7 or R-9 at best. That lets Valley heat radiate through the ceiling drywall and turn upstairs rooms into ovens by 3 p.m.
- Unsealed top plates and knob-and-tube penetrations. Older attics around Burbank Boulevard and Lankershim Boulevard often have gaps where interior walls meet the ceiling. Conditioned air leaks straight up, and attic heat pours down.
- Zero insulation in dingbat apartment conversions. Many of the mid-century apartment buildings near the NoHo Arts District have no wall insulation and only a thin layer of attic fiber if any at all. Party-line walls let heat move between units, so a single attic retrofit won’t solve everything.
- Recessed lights and unsealed penetrations that get skipped. Tight access through alley-loaded garage hatches and small closet openings leads some crews to blow insulation without air-sealing around recessed lights or top plates first. That leaves the upgrade only partially effective.

Attic cleaning adds $800 to $1,500, and mold removal runs $1,200 to $2,800.

FAQs About Attic Insulation in North Hollywood
Yes, we can insulate the attic, but you should understand it won’t solve all the heat transfer. In a dingbat apartment conversion with unsealed party-line walls, you’ll still get heat moving sideways between units. What we can do is air-seal the attic floor, insulate to R-49, and add a radiant barrier if the roof framing allows. That cuts the biggest heat source, the attic, which is usually the main culprit during Valley summers. Wall insulation is a different scope, but we can assess it while we’re up there. Call (833) 390-3099 and we’ll schedule a look.
We plan for it before we arrive. For alley-loaded garages and townhome clusters off Coldwater Canyon or near the Arts District, we use compact equipment and stage materials in the alley or at the curb with permits if needed. We don’t need a truck parked directly beside the hatch. The hose runs from the street, through the home, up through the ceiling access, and into the attic. Our crews are used to working in tight hallways and closets, and we lay drop cloths along the full path. Tell us about the access when you call and we’ll plan accordingly.
R-49 for blown-in fiberglass, which is about 16 to 18 inches of settled material. That’s above the current Title 24 minimum. Some older North Hollywood attics have settled material at R-7 to R-9, which is effectively nothing during a July heat wave. We also recommend a radiant barrier on south-facing roof slopes to deflect the worst of the afternoon sun, and air sealing around top plates and recessed lights before we blow anything in. Without air sealing, even R-49 underperforms.
Yes, regularly. The pattern is bathroom exhaust fans venting into the attic instead of through the roof, unvented laundry rooms, and the Valley’s combination of high heat and occasional humidity spikes. South-facing roof sheathing is the most common location. If we find mold during an insulation retrofit, we’ll stop and show you before proceeding. The fix is mold removal, air sealing, and then new insulation. We never blow fresh fiberglass over moldy framing.
Most jobs take one to two days. A straightforward blown-in insulation retrofit on a 1,200-square-foot tract home near Burbank Boulevard with open attic access runs about six to eight hours. If we’re removing old settled rock-wool first, adding air sealing, or dealing with tight access through a closet hatch, plan on two days. Spray foam adds a day because the foam needs cure time before we replace any decking or sheathing. We’ll give you a schedule in the estimate.
