Spray Foam Insulation Cost — Same-Day Service, Done Right the First Time

How Much Does Spray Foam Insulation Cost in Hollywood?

Spray foam insulation in Hollywood runs about $1,200 to $2,400 for a typical 1,000-square-foot attic or open framing area using closed-cell foam, and roughly $850 to $1,700 for open-cell in the same space. On a dollars-per-square-foot basis, expect $1.75 to $3.50 per square foot for closed-cell and $1.00 to $2.00 per square foot for open-cell. Most Hollywood homes we quote land between $1,800 and $4,200 because the older housing stock here tends to need air sealing, irregular framing work, and moisture control before the foam even goes in.

We’re Hollywood Insulation Co. Our Spray Foam Insulation services are one of the three insulation methods we install (the others are attic insulation and blown-in). We work with both Icynene and Demilec spray foam systems, which means you get the right system for your house rather than whatever a crew happens to stock. Every estimate is free, and we quote you in dollars, not in “it depends.”

Key Takeaways

• Closed-cell spray foam in Hollywood: $1.75-$3.50 per square foot, or $1,200-$2,400 for a 1,000 sq ft job.
• Open-cell spray foam: $1.00-$2.00 per square foot, or $850-$1,700 for the same area.
• A full attic often costs more than the square footage suggests, because of air sealing, knee walls, and the 1920s-1940s construction we see in neighborhoods like Los Feliz and East Hollywood.
• Spray foam costs more up front than fiberglass or cellulose, but it air seals and insulates in one step.

Spray Foam Insulation Cost Breakdown (2026)

These are the ranges we see in Hollywood for 2026. Your actual number depends on the details below, but this table gives you something real to budget against.

What drives cost up or down? The two biggest levers are foam type (closed-cell costs roughly twice open-cell per square foot because it’s denser and takes longer to apply) and access difficulty. A clean, open attic with a wide hatch is quick. A 1925 Spanish bungalow in East Hollywood with a 24-inch crawl hatch, knob-and-tube wiring to work around, and a partially finished attic takes longer, and that shows up in the quote. Square footage matters, but it’s rarely the whole story.

One thing we tell every homeowner: don’t compare a spray foam quote to a fiberglass quote as if they were the same product. Spray foam seals air leaks and insulates in one step. Fiberglass batts don’t air seal at all. That’s why we carry Owens Corning, Johns Manville, CertainTeed, and Knauf fiberglass alongside our foam systems. When you compare, compare total outcomes, not just the line-item price. We’ll tell you honestly when batts or blown-in are the smarter money.

What Affects Spray Foam Insulation Pricing in Hollywood

Hollywood isn’t a single housing market. You can drive from a 1918 Craftsman in Hollywood Heights to a 1960s stucco box in Hollywood Studio District to a hillside home in the Hollywood Hills with a sloped ceiling and a knee wall running the length of it. Each one prices out differently. Here’s what actually moves the number.

• Home age and construction style. Most Hollywood homes we work in were built before 1960. That means irregular framing, old plaster, and attic spaces that were never designed for modern insulation. Prep work compounds. A 1940s bungalow near Hollywood Boulevard often needs a half day of air sealing before we run foam, while a newer build can go straight to application.
• Attic geometry. Open attic floors are straightforward. Vaulted ceilings, knee walls, dormers, and attic conversions are not. Homes in the Hollywood Hills and parts of Los Feliz frequently have sloped ceilings that require closed-cell foam applied to the roof deck rather than the floor, which costs more per square foot but solves the problem properly.
• Foam type. Closed-cell runs roughly $1.75-$3.50/sq ft; open-cell runs about $1.00-$2.00. Closed-cell performs better where moisture and heat gain are concerns, which is most of the Hollywood year.
• Air sealing scope. The penetration points around plumbing stacks, recessed lights, and wiring are where Hollywood homes leak the most. Sealing those adds $200-$600 but is often the highest-return line item on the whole job.
• Access. A tight crawl hatch or a steep roof pitch on a hillside property slows the crew down. This is a labor-driven trade, so access time shows up in the price.
• Existing insulation removal. If the attic holds old batt insulation that’s slumped or moisture-damaged, it has to come out before foam goes in. Removal and disposal typically adds $300-$800 depending on volume.

There’s a local climate factor worth naming. Hollywood sits in a warm, dry climate, but our daytime temperature swings and the heat that builds in west-facing attics are severe. The right foam system for a west-facing attic in Studio City-adjacent hills is often closed-cell for its moisture resistance and heat performance, while an interior wall in a milder spot may do perfectly well with open-cell. That’s why we stock both Icynene and Demilec systems rather than one. If you want a deeper look at how we match material to climate, our main service overview covers it.

We also want to be straight about what we don’t do. We’re a dedicated insulation specialist, not a general contractor. We install spray foam, blown-in, and attic insulation. That’s it. If your project needs something outside that scope, we’ll tell you.

Spray Foam vs. Fiberglass vs. Blown-In: What Actually Costs Less Over Time

The lowest quote isn’t always the lowest cost. Here’s how the three methods compare for a Hollywood homeowner looking at a 1,000-square-foot attic:

• Fiberglass batts (Owens Corning, Johns Manville, CertainTeed, Knauf): roughly $1,200-$2,600 installed. Lowest up-front cost. No air sealing, and batts can sag or gap over time.
• Blown-in cellulose (GreenFiber) or fiberglass: roughly $1,400-$3,000 installed. Fills irregular spaces well; cellulose brings recycled content and decent sound damping.
• Open-cell spray foam (Icynene, Demilec): roughly $850-$1,700 for 1,000 sq ft in open areas, but costs more in complex geometry. Air seals as it insulates. Excellent sound control.
• Closed-cell spray foam: roughly $1,200-$2,400 and up. Highest R-value per inch, acts as its own vapor barrier, strongest air-sealing performance.

The honest answer is that spray foam usually wins on performance per square inch, and fiberglass or cellulose usually wins on up-front price. The right call depends on your attic, your goals, and your budget. We carry all of it, which means our recommendation isn’t tied to what we have on the truck. For more on the alternatives, see our guides on spray foam in Hollywood and how it stacks up against blown-in and batt.

How to Save on Spray Foam Insulation

Here’s what actually works, based on the jobs we quote every week in Hollywood.

1. Bundle several areas into one job. Foam is applied by the truckload. If you’re doing the attic, do the rim joists and knee walls at the same time. Combining them typically costs less than three separate jobs because there’s one mobilization.
2. Choose open-cell where it fits. If you don’t need the moisture barrier or the higher R-value per inch of closed-cell, open-cell saves real money with a modest performance trade-off.
3. Fix the air leaks first, or save up for a proper job. Partial spray foam that leaves penetrations unsealed costs almost as much and underperforms. A complete, correct job is more cost-effective than a cheap, incomplete one.
4. Ask about material alternatives. In some attics, blown-in cellulose from GreenFiber or mineral wool from Rockwool performs close to foam for less. We’ll show you the numbers and let you decide.
5. Get multiple quotes, and compare outcomes, not just prices. A quote that excludes prep, air sealing, and removal isn’t cheaper. It’s just shorter.

Free estimates are the starting point. Call (866) 605-6949 and we’ll have a real conversation about your attic, your energy bills, and what makes sense for your budget. No pressure, no upselling.

Is Spray Foam Insulation Worth the Cost in Hollywood?

Yes, for most Hollywood homes. Spray foam costs more up front than fiberglass or cellulose, but it air seals and insulates in one step. In our experience, homeowners notice the difference on their energy bills and in room comfort within the first heating and cooling season. No more hot west-facing bedrooms in July, no more cold spots around the fireplace or over the garage.

Where it’s clearly worth it: older homes with big air leaks, homes with hard-to-insulate spaces like knee walls and sloped ceilings, and homes where the current insulation is doing nothing to stop drafts. Where it’s a judgment call: a newer home with already-decent insulation and only a modest energy bill, where open-cell or blown-in might do the job for less. We’ll give you an honest recommendation on which side of that line your home is on.

Can Spray Foam Be Installed Year-Round in Hollywood?

Yes. Hollywood’s climate is mild enough that spray foam can be applied year-round, though we do watch attic temperatures on the hottest days and schedule accordingly. Unlike some climates where foam application is limited to specific seasons, Hollywood crews can work almost any week of the year. That means no long waits and no seasonal premium.

If you’re planning to install before summer to get ahead of the heat, call (866) 605-6949 and we’ll get you on the schedule.

Why Hollywood Insulation Co for Spray Foam?

Three reasons, and they’re specific.

We’re a specialist, not a generalist. Every project, every technician, every day is spent diagnosing thermal bypasses, air leakage, and R-value deficiencies. We aren’t a general contractor with insulation on the side. This trade is the whole job.

Eight brands, one honest recommendation. We install Owens Corning, Johns Manville, Knauf, Rockwool, CertainTeed, Icynene, Demilec, and GreenFiber. That’s fiberglass, mineral wool, spray foam, and cellulose under one roof. The solution gets chosen for your home, not for what’s convenient to install.

Three installation methods, matched to the application. Spray foam, attic insulation, and blown-in. We install all three because no single method is right for every situation. If spray foam is overkill for your attic, we’ll tell you. If it’s exactly right, we’ll show you why and quantify it.

We don’t publish claims about years in business, review counts, or guarantees without verified facts behind them. What we will promise you is a free estimate, an honest recommendation, and clean work done right. If something doesn’t measure up, we come back.

FAQs – Spray Foam Insulation Cost

How much does spray foam insulation cost in Hollywood?

Spray foam insulation in Hollywood costs about $1.00-$3.50 per square foot depending on foam type and job complexity, which comes to roughly $1,200-$2,400 for a 1,000-square-foot attic using closed-cell foam, or $850-$1,700 for open-cell. Call (866) 605-6949 for an exact quote; estimates are free.

Is it cheaper to repair my existing insulation or install spray foam?

If your existing insulation is fiberglass or cellulose, patching it usually costs less up front ($200-$600 for a small repair), but if it’s slumped, moisture-damaged, or constantly drafted, replacing it with spray foam is the better long-term spend. Spray foam at $1,200-$2,400 for a 1,000-square-foot attic air seals and insulates in one step. Call (866) 605-6949 and we’ll walk through your specific situation.

How much does spray foam cost for a whole house in Hollywood?

A whole-house spray foam job in Hollywood typically runs $3,000-$8,000 for a 1,500-2,000-square-foot home, depending on how much of the envelope you’re sealing (attic floor, rim joists, knee walls, walls). Call (866) 605-6949 for a number specific to your home.

Do I need to be home during spray foam installation?

Plan to be off-site during application. Spray foam off-gasses during cure, so the standard practice is for the crew to apply, ventilate, and confirm the space is ready before you return, usually the same day or the next morning. That’s one day of disruption for a much tighter envelope. Call (866) 605-6949 to plan your timing.

Is spray foam more expensive than fiberglass in Hollywood?

Yes, spray foam costs more up front than fiberglass: closed-cell runs $1.75-$3.50 per square foot compared to about $1.20-$2.60 for fiberglass batts installed. The tradeoff is air sealing and higher R-value per inch, which often pays back over time. Call (866) 605-6949 and we’ll give you a side-by-side for your attic.
