How Much Does Insulation Removal & Replacement Cost in Hollywood?
Insulation removal and replacement in Hollywood typically runs $2,400 to $6,800 for a whole-house attic job, with most single-family homes landing near $3,900. Removal alone (hauling out old fiberglass, cellulose, or contaminated material) costs $1.00 to $2.20 per square foot, and the new installation adds $1.50 to $4.50 per square foot depending on the material you choose. A 1,200-square-foot Hollywood bungalow with degraded batt insulation and a full replacement in blown-in cellulose is a very common job that comes in around $3,200 to $4,100.
Those numbers assume a standard pitched attic with accessible working space. Older Hollywood Hills homes with tight knee-wall attics, low clearances, or decades of accumulated debris push toward the top of the range. We’ll get into exactly what moves the price below.
- Typical whole-home range: $2,400 – $6,800
- Removal only: $1.00 – $2.20 per sq ft
- New installation: $1.50 – $4.50 per sq ft
- Most Hollywood jobs land near: $3,900
Insulation Removal & Replacement Cost Breakdown (2026)
Here’s how the line items break out for a Hollywood project in 2026. Use these ranges to sanity-check any quote you receive, including ours.
| Line Item | Price Range | Notes |
|---|---|---|
| Old insulation removal (per sq ft) | $1.00 – $2.20 | Includes vacuum extraction and disposal; contaminated or pest-damaged material sits at the high end |
| Blown-in fiberglass installation (per sq ft) | $1.50 – $2.60 | Good baseline R-value; most affordable replacement path |
| Blown-in cellulose, GreenFiber (per sq ft) | $1.80 – $3.00 | Recycled content, strong for fire resistance and sound control |
| Batt insulation, Owens Corning / Johns Manville (per sq ft) | $1.70 – $3.20 | Common for open, accessible attic floors |
| Mineral wool, Rockwool (per sq ft) | $2.60 – $4.20 | Preferred where fire resistance and acoustic control matter |
| Open-cell spray foam, Icynene (per sq ft) | $2.20 – $3.80 | Air sealing plus insulation in one pass |
| Closed-cell spray foam, Demilec (per sq ft) | $3.50 – $5.50 | Highest R-value per inch; moisture barrier performance |
| Air sealing / thermal bypass work (flat) | $300 – $900 | Sealing top plates, penetrations, and chases before new insulation goes in |
| Attic baffles / ventilation correction (flat) | $250 – $700 | Keeps airflow at the eaves and prevents insulation blocking |
| Disposal and haul-away (included in removal) | – | Contaminated material may add a separate handling fee |
For a whole-home job, expect the removal and the new material to be roughly equal halves of the bill, with spray foam on the high side because it’s both a material and a labor-intensive application. Something that pushes a typical Hollywood quote up: a home built before 1978 where the old insulation may contain hazardous debris, gutted remodels that left mixed materials in the attic, and Hollywood Hills homes with steep roofs and limited attic access.
What keeps a quote lower: an empty attic you can reach through a standard scuttle, standard 2×4 or 2×6 framing, and a home where you’re replacing like-for-like rather than upgrading the method.
What Affects Insulation Removal & Replacement Pricing in Hollywood
No two Hollywood attics quote the same. Here’s the list we walk through with every homeowner, and it’s the same list that drives the numbers above.
- Attic size and accessibility. A 1,000-square-foot flat attic is a quick job. A 2,200-square-foot Hollywood Hills home with a low, angled attic and knee walls takes three times as long, and labor is the biggest line item. If the crew needs to work on hands and knees or squeeze through a tight scuttle, expect the labor side to climb.
- Condition of the old insulation. Compressed, matted fiberglass with settled R-value is routine. Pest-damaged, water-stained, or rodent-contaminated material requires careful extraction and disposal, and that’s where removal prices land in the $2.00+ per square foot range. If you’ve had a roof leak in the last few years, the material beneath it needs to come out, not just get topped off.
- Material choice. This is the biggest swing on the new-install side. Blown-in fiberglass is the budget path, GreenFiber cellulose and Rockwool mineral wool sit in the middle, and closed-cell Demilec foam tops the scale because it delivers R-value and air sealing together. The right pick depends on your attic, not on what’s cheapest.
- Air sealing scope. If the old insulation comes out, sealing thermal bypasses is the right move while the attic is open. Recessing a can light, sealing a top plate, or closing off a plumbing chase all add small amounts that compound into real energy savings. Skipping this step means the new insulation goes in over the same leaks.
- Roof and attic geometry. Hollywood homes near the hills often have low-slope or steep-pitch roofs, dormers, and awkward ventilation paths. Attic baffles and ventilation correction keep insulation from choking airflow at the eaves, and that’s often a necessary extra step for a home that’s had ice-dam-like condensation or heat buildup.
- Code-driven R-value targets. California’s energy code sets an R-value target for our climate zone, and reaching it sometimes means more material than the old attic held. If your home was built in the 1950s or 1960s, the original insulation was installed to a much lower standard, so the replacement will use more material to hit current specs.
If you’re weighing whether to remove and replace versus top off what’s there, our guide to insulation removal and replacement in Hollywood walks through when a full removal is the right call and when it isn’t. We’d rather tell you the honest answer than sell you a job you don’t need.
How to Save on Insulation Removal & Replacement
There’s no trick to shaving a real budget here, but a few sensible choices do move the number:
- Bundle removal and replacement in one visit. A single trip for extraction and install is cheaper than two service calls. Every quote we give prices them together for that reason.
- Choose the material that fits the attic, not the one with the highest R-value on the brochure. If your attic is well-vented and accessible, blown-in cellulose from GreenFiber often delivers the same comfort result as spray foam at a fraction of the cost. If you’ve got chronic air leaks and ductwork in the attic, the foam may save more over time.
- Seal air leaks while the attic is open. It’s the single highest-return step. A few hundred dollars of air sealing prevents your new insulation from being undermined by the same leaks the old material was fighting.
- Get more than one quote and compare line items, not just totals. A quote that’s $1,000 cheaper usually skipped air sealing, baffles, or disposal, and you’ll pay for those later.
- Ask about utility rebates and incentives. Southern California utilities periodically offer insulation rebates, and a knowledgeable installer will tell you the current programs and handle the paperwork.

FAQs – Insulation Removal & Replacement Cost
Is it cheaper to repair or replace attic insulation in Hollywood?
Replacing is usually cheaper in the long run when the old insulation is contaminated, wet, or compressed below an effective R-value, because a top-off over damaged material still leaves the leaks and settling that caused the problem. A removal and full replacement for a typical Hollywood home runs $2,400 to $6,800, while repeatedly topping off bad insulation can cost nearly as much over time without fixing comfort. Call (866) 605-6949 for a free look and an honest read on which path fits your attic.
How much does it cost to remove old insulation in Hollywood?
Removal alone runs $1.00 to $2.20 per square foot in the Hollywood market, so a 1,200-square-foot attic lands roughly $1,200 to $2,600 for extraction and haul-away. Contaminated or pest-damaged material sits at the high end because it needs careful handling and disposal. We quote removal and replacement together so you see the full picture, and estimates are free at (866) 605-6949.
How long does insulation removal and replacement take?
Most single-family Hollywood attics are a one-day job, usually 5 to 8 hours for a standard home with good access, while larger Hollywood Hills homes or jobs with heavy contamination can take two days. Spray foam applications run longer than blown-in because of setup, cure time, and the precision of the application. Call (866) 605-6949 and we can give you a realistic window when we see the attic.
Does replacing insulation lower my energy bills in Hollywood?
Yes, when the old insulation was underperforming. Homes built before 1978 commonly have insulation well below current California targets, and bringing it up to spec in a tight, sealed attic often shows up on the next few utility bills. The size of the savings depends on how much air leakage and thermal bypass the attic had; air sealing alongside the new insulation is what makes the difference. Call (866) 605-6949 for a free assessment before you commit to a number.
Do you remove old insulation when you install spray foam?
Sometimes, and it depends on what’s there. Closed-cell Demilec foam goes in over a clean, sealed cavity, and that almost always means the old degraded material comes out first so the foam bonds correctly. Open-cell Icynene can be applied in some situations with less prep, but a proper job still requires removing anything wet, contaminated, or loose.

Why the Right Team Matters on a Removal and Replacement Job
Insulation removal looks simple from the outside. In practice, a lot of what makes the job last is what happens before the new material goes in: sealing thermal bypasses, fixing ventilation paths, and matching the material to the attic instead of whatever happens to be on the truck. Hollywood Insulation Co is a dedicated insulation specialist, not a general contractor with insulation on the side. That shapes how we quote.
We carry eight manufacturer brands across the major categories: Owens Corning, Johns Manville, CertainTeed, and Knauf for fiberglass; Rockwool for mineral wool; Icynene and Demilec for open-cell and closed-cell spray foam; and GreenFiber for recycled cellulose. Three installation methods sit under one roof (attic insulation, spray foam, and blown-in), so the recommendation follows the home rather than a single method. If you’re comparing options, our page on Hollywood insulation services covers the full picture, and our home page covers who we are.
We can’t claim years in business or a review count in writing until those facts are verified, so we won’t. What we can tell you is that every technician we send is focused on this one trade, because diagnosing air leakage, thermal bypasses, and R-value shortfalls is the whole job, not a side service.
For homes and builders in Hollywood who want a partner that can specify the right material for the application, we’re glad to talk through the options. Builders and remodelers working in the hills, in older bungalows, and in gut renovations get the same method-matching approach as a homeowner with a cold spare bedroom.

What Our Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
