Trusted Insulation Removal & Replacement for Santa Monica Homeowners
Old insulation does not just underperform. It actively works against your home, trapping moisture, housing rodents, and driving up your monthly energy bill while you wonder why the house never feels comfortable. We have been removing and replacing failed insulation in Santa Monica homes since 2000, and the problems we see follow a pattern: damp coastal air working its way into attics, decades of accumulated dust and pest debris, and insulation that simply gave up years ago. Walt Brenner and his crew answer the phone live, 24/7, and we can typically get a technician to your Santa Monica home the same day you call. Reach us at (424) 396-5828 for a straight answer and a free estimate.

What Our Insulation Removal & Replacement Service Includes
Insulation removal is not a one-size-fits-all job. The approach depends on what is up there, why it failed, and what condition your attic is in. We break the work into four categories so you know exactly what you are paying for and why it matters. Every job starts with a full attic inspection, and every job ends with the Done Right Promise behind it.
Attic Insulation Removal
Most Santa Monica homes have blown-in fiberglass or cellulose sitting in the attic, and after 15 to 25 years, that material compresses to a fraction of its original R-value. We use commercial-grade vacuum extraction equipment to remove old attic insulation completely, down to the drywall, without kicking dust into your living space. Once the cavity is clear, we inspect the framing, wiring, and ductwork before anything new goes in. This is the standard first step when upgrading attic insulation in an older Santa Monica house.

Contaminated Insulation Removal
Rodents, birds, and feral cats find attics in Santa Monica just as appealing as homeowners do. When animals nest in insulation, they leave behind droppings, urine, and parasites that make the material a health hazard to remove without proper gear. We suit up with respirators and protective equipment, remove the contaminated material, sanitize the attic floor, and rodent-proof entry points so the problem does not come back. After that, we install fresh insulation and you start over with a clean, dry attic.

Vermiculite & Old Insulation Removal
Homes built before 1990 in Santa Monica and the surrounding beach communities sometimes have vermiculite insulation, which can contain asbestos fibers. We never disturb vermiculite casually. Our technicians follow strict containment protocols, and if testing indicates asbestos, we coordinate with licensed abatement specialists while handling the rest of your removal. For non-hazardous old fiberglass and rock wool, we extract everything and prepare the attic for a modern, code-compliant installation.

Insulation Replacement
Once the old material is out, the real performance gains come from what goes back in. We install blown-in fiberglass from Owens Corning or Johns Manville, spray foam from Demilec or Icynene, and mineral wool batts from Rockwool, all matched to Santa Monica’s marine climate and the specific needs of your home. We air-seal the attic floor before reinstalling, which matters more than most homeowners realize because gaps around can lights, plumbing vents, and top plates leak conditioned air straight out of the house. New insulation installed without air sealing is a half-measure, and we do not do half-measures.

Brands We Service for Insulation Removal & Replacement
We remove and replace every type of insulation found in Santa Monica homes, but our installs focus on products from manufacturers we trust: Owens Corning, Johns Manville, Knauf, and Rockwool. Owens Corning blown-in fiberglass is our go-to for most attics because it settles predictably, holds its R-value over time, and does not absorb moisture the way cellulose can near the coast. We have installed hundreds of Owens Corning attics across Santa Monica, Marina del Rey, and Ladera Heights, and we know exactly how many bags a given square footage needs to hit R-38 or R-49.
Rockwool mineral wool is the right call for homes where moisture and sound are concerns, especially in the fog belt near the beach. It repels water, does not burn, and adds real acoustic dampening between floors. For spray foam jobs, we install Demilec and Icynene closed-cell and open-cell products, and for blown-in work we also carry Knauf fiberglass. We service and remove all brands, including old Johns Manville batt insulation from the 1970s and 80s. Whether you have Owens Corning from last decade or mystery loose-fill from 1962, we know how to handle it.
Signs You Need Insulation Removal & Replacement Right Now
- Your energy bills keep climbing while the house stays uncomfortable. When attic insulation compresses or gets wet, its R-value drops sharply. A Santa Monica home that needs R-38 in the attic but only has 4 inches of flattened fiberglass is spending real money every month heating and cooling the sky.
- You hear scratching, scurrying, or thumping in the attic at night. Rats and squirrels in Santa Monica attics shred insulation, compress it with nests, and leave droppings throughout the material. Damaged, contaminated insulation should come out, not get covered over with a fresh layer.
- You see moisture stains on ceilings or walls below the attic. Coastal humidity, bathroom exhaust fans venting into the attic, and roof leaks all wet the insulation from above. Wet insulation loses its thermal performance and becomes a mold risk. Removing it and fixing the moisture source is the only real fix.
- Your attic insulation looks thin, uneven, or darker than it should be. Take a look. If you can see the tops of the ceiling joists, you have less than 6 inches of insulation, which means R-19 or lower. Santa Monica building standards recommend R-38 or better. Dark, dirty insulation has been filtering air and dust for years, which means it is working as a filter, not a barrier.
- Rooms upstairs are 8 to 10 degrees hotter than downstairs in summer. That temperature gap usually points to attic insulation and air sealing failure. Santa Monica summers may be mild by Inland Empire standards, but a poorly insulated top floor still bakes by afternoon. New insulation plus proper air sealing evens things out and reduces the load on your HVAC system.
Our Insulation Removal & Replacement Process - Step by Step
- 1
Attic inspection and diagnostic walkthrough. We start by going up and seeing exactly what you have: type, depth, condition, moisture levels, pest activity, and air leakage points. We check the attic hatch, can lights, bathroom vents, and ductwork. You get a written summary of findings before any work is quoted.
- 2
Containment and preparation. Before extraction begins, we seal off the attic access with plastic sheeting and set up negative air pressure so dust and fibers do not drift into your living area. Floors are protected, and the work path from the front door to the attic is covered. We treat your home like we live there.
- 3
Full insulation extraction. Using a high-power HEPA-filtered vacuum system, we remove all old insulation down to the drywall. For contaminated material, our technicians wear full PPE and bag everything for proper disposal. For vermiculite, we follow testing and containment protocols before touching anything.
- 4
Air sealing, cleaning, and rodent proofing. Once the attic is empty, we seal the gaps: wire penetrations, top plates, recessed lights with rated covers, plumbing stacks, and the attic hatch. We seal or screen entry points for rodents. If needed, we sanitize the attic floor and treat for lingering odors. This step is where the real energy savings come from, and it is what separates our work from a simple blow-and-go job.
- 5
New insulation installation and final inspection. We install the replacement material to current Santa Monica code levels (typically R-38 for attics), fluff it properly, and verify consistent depth across the entire attic. We photograph the finished job, walk you through what we did, and register the work under the Done Right Promise. If anything is not right, you call us and we come back. That is the whole point of the guarantee.
How Much Does Insulation Removal & Replacement Cost in Santa Monica?
A typical attic insulation removal and replacement in Santa Monica runs $1,800 to $4,500 for a standard 1,200 to 2,000 square foot single-family home. Contaminated insulation removal with sanitation and rodent proofing typically adds $400 to $1,200 depending on the extent of the damage. Full spray foam replacement on a larger attic can run $4,000 to $8,000 because of material cost and application time.
Here is how the pricing breaks down:

- Attic insulation removal only: $800 to $1,600 for a typical Santa Monica attic.
- Removal plus blown-in fiberglass replacement (R-38): $1,800 to $3,200.
- Removal plus spray foam replacement: $3,800 to $7,500 depending on square footage and foam type.
- Contaminated removal with sanitation and rodent proofing: $2,400 to $5,000 combined with replacement.
- Vermiculite removal (non-asbestos): $3,000 to $6,000 due to specialized handling and disposal.
What affects the price: attic size and access (crawlspace attics in older Santa Monica bungalows cost more because the work is slower), insulation type, moisture damage, pest contamination, and whether air sealing is included. Every estimate we provide is free, itemized, and fixed upfront. No trip charge inside our service county, and seniors and veterans always save 10%.
