Closed Cell Spray Foam Insulation
Closed Cell Spray Foam Insulation is the densest residential foam we install; how much Spray Foam Insulation costs in Torrance runs about $3.50 to $6.50 per board foot depending on depth and access. It cures rigid, adds structural strength to walls and roofs, and acts as a vapor barrier on its own. We recommend it for crawl spaces near the coast, rim joists, and any area where moisture from the marine layer is a recurring problem. Laurel Attic Insulation Torrance installs closed cell foam in new construction, retrofits, and tight-access areas where fiberglass simply can’t seal. Most closed cell jobs run $2,900 to $7,200 depending on square footage.
Where Closed Cell Earns Its Cost
Closed cell is the right call when you need waterproofing plus insulation in the same pass. We use it under floors, against foundation walls, and in rim joists where air and moisture both sneak in.
Why Torrance Homes Favor It
Homes within three miles of the beach deal with salt air and humidity that open cell can’t fully block. Closed cell seals those gaps with a vapor-tight barrier that won’t sag or absorb water over time.
Open Cell Spray Foam
Open Cell Spray Foam is a lighter, softer foam that expands dramatically after spraying, typically costing $1.80 to $3.20 per board foot in Torrance. It’s our go-to for attic ceilings and interior walls where sound control and air sealing matter more than moisture blocking. Open cell fills every crack and odd cavity, then cures into a spongy blanket that stops air movement but still lets the structure breathe. Laurel Attic Insulation Torrance installs it most often in existing attic conversions and interior partition walls. Expect most open cell jobs to land between $1,900 and $5,400.
Sound Control in Busy Neighborhoods
Open cell dampens noise better than nearly any other insulation type. If you’re near Torrance Boulevard or the 405, we routinely use it in bedroom walls to cut road noise dramatically.
Attic Ceilings Without the Weight
Open cell adds almost no structural load, which matters in older Torrance homes with truss systems not built for heavy materials. It seals the ceiling plane completely while keeping attic temperatures stable.
Spray Foam Insulation Contractors
Our Spray Foam Insulation in Torrance is applied by licensed contractors using specialized rigs, and we’re one of the few that handle both open and closed cell formulations. We show up with calibrated proportioning equipment, not a truck full of leftovers. Laurel Attic Insulation Torrance has been doing foam work since 2003 under Chase Whitaker’s direction, with every technician background-checked and uniformed. The labor portion of a foam job in Torrance typically runs $1,000 to $2,800, bundled into the board foot pricing we quote upfront.

Book in a tap, get a live arrival time, receive before-and-after photos, and pay from the link. That’s the Relay Standard we built Laurel on, and it’s included on every spray foam job.
Written Price Before Work Starts
We deliver a written price before anything gets sprayed, every time. No door-step surprises, no vague estimates, and no renegotiation once the hoses come out.
Spray Foam Attic Insulation
Spray Foam Attic Insulation is foam applied directly to the underside of your roof deck, turning the attic into conditioned space and stopping heat before it enters your home, with Torrance jobs typically running $2,800 to $7,800. This is the single highest-impact insulation upgrade for South Bay homes, especially those with HVAC equipment or ducting in the attic. Instead of trapping heat under fiberglass batts, the foam seals the entire roofline. Laurel Attic Insulation Torrance installs both open and closed cell in attics, matched to your ventilation setup and roof structure.
Roofline Sealing vs. Floor Batts
Traditional attic insulation sits on the attic floor, leaving the attic itself hot as an oven. Spraying the roofline keeps the whole attic within a few degrees of your living space, which protects ducts and lowers cooling load.
Older Torrance Home Retrofit
Many 1950s and 1960s ranch homes in central Torrance have minimal attic ventilation. We adapt the foam type and depth to work with your existing roof framing, never against it.
Spray Foam Wall Insulation
Spray Foam Wall Insulation is foam injected into wall cavities during construction or through small access holes in existing homes, costing between $2,000 and $5,800 for a typical Torrance retrofit. It stops the constant air exchange that fiberglass batts allow, which is why rooms with foam walls hold temperature noticeably better. We handle both new construction open-wall applications and injection retrofits with minimal drywall damage. Laurel Attic Insulation Torrance uses closed cell for exterior walls and open cell for interior partition walls.
Retrofit Without Gutting Your Walls
We can inject foam through small drill holes from inside or outside, then patch the openings cleanly. Most Torrance homeowners have us in and out in one day with no interior demolition.
New Construction Open Walls
If you’re adding a room or doing a full gut renovation, we spray stud bays before drywall goes up. It’s the most complete air seal possible, and it’s easier and cleaner than trying to retrofit later.
Rim Joist Spray Foam
Rim Joist Spray Foam is foam applied to the band board where your floor framing meets the foundation, with most Torrance homes costing $900 to $2,400 depending on linear footage and access. This thin band around your house is one of the biggest air leaks in any structure, and fiberglass batts stuffed into rim joists do almost nothing to stop it. Closed cell foam seals the entire perimeter airtight and blocks moisture from the crawl space or basement. Laurel Attic Insulation Torrance does rim joist work most often in raised foundations, which are common throughout Torrance, Compton Spray Foam Insulation, and the South Bay.
Raised Foundation Homes
Torrance has thousands of homes built on raised foundations with accessible crawl spaces. If you can see daylight around your rim joist from the crawl space, you’re paying to condition outside air all year.
Closed Cell Is the Only Real Fix
Open cell doesn’t belong in rim joists. The foam sits against the foundation and sees ground moisture, so we use closed cell exclusively here, giving you a vapor-tight seal that won’t wick water.
Crawl Space Spray Foam Insulation
Crawl Space Spray Foam Insulation is foam applied to the underside of the floor or the crawl space walls, with Torrance jobs typically running $2,200 to $6,500 depending on square footage and whether you choose encapsulation. Open crawl spaces pull damp air into your house all day, carrying whatever smells and mold spores live down there. Sealing the crawl space with foam keeps that air out and your floors warmer. Laurel Attic Insulation Torrance installs both floor-deck foam and full crawl space encapsulation with closed cell.
Floor Deck Underside Application
We spray the underside of your subfloor between floor joists when the crawl space stays vented. It stops cold floors in winter and keeps conditioned air from being pulled down through gaps.
Full Encapsulation with Foam Walls
For crawl spaces with standing water or heavy moisture, we recommend sealing the walls and floor with closed cell and adding a vapor barrier. It converts a damp crawl space into a dry, conditioned storage zone.
Garage Spray Foam Insulation
Garage Spray Foam Insulation is foam applied to garage ceiling, walls, or the shared wall with your house, with most Torrance garages running $1,400 to $3,800 depending on size and finish level. Garages are typically left uninsulated, which means any attached garage is a giant thermal hole on the side of your house. Sealing the garage ceiling and the shared wall makes a noticeable difference in the rooms above and adjacent to the garage. Laurel Attic Insulation Torrance handles detached and attached garages in Torrance and Hawthorne Spray Foam Insulation, including bonus rooms over the garage.
Attached Garage Shared Wall
The wall between your garage and your living room is almost never insulated properly in older Torrance builds. We spray it with closed cell to keep exhaust fumes and temperature swings on the garage side.
Bonus Rooms Above the Garage
If you have a bedroom or office over the garage, you already know it’s the hottest room in summer. Spraying the garage ceiling from below fixes that without touching finished living space.
Brands We Service
We install and service Owens Corning spray foam products, including their closed cell and open cell formulations. Owens Corning foam delivers consistent expansion rates, which matters when you’re spraying in tight Torrance attics where over-expansion can bow drywall. Our crew is trained on their full product line and we’ve been working with it since 2003.
We also work extensively with Icynene and Demilec foam systems. Icynene open cell is our go-to for sound-focused wall applications, while Demilec closed cell handles the high-moisture South Bay crawl spaces better than nearly anything else on the market. If you already have one of these brands in place, we can match it for a seamless repair. Whether it’s Owens Corning, Icynene, Demilec, or any other reputable foam system, we can help.
Signs You Need a Pro Right Now
- Your second floor won’t cool below 78°F in summer. This usually means your attic floor insulation isn’t stopping radiant heat. Spray foam on the roofline changes the entire dynamic, and the difference is immediate.
- You can smell the crawl space when the AC kicks on. Your HVAC return is pulling musty air from below the house through floor gaps. Sealing the crawl space with closed cell stops that airflow permanently.
- Rooms above the garage feel 10+ degrees hotter than the rest of the house. Uninsulated garage ceilings radiate heat upward all afternoon. Foam applied from below solves it without any drywall work upstairs.
- Your energy bills spike every December and July. Torrance’s mild seasons hide air leaks, but temperature extremes expose them. A foam air seal smooths out those seasonal spikes significantly.
- You’ve had rodent issues in the attic or crawl space. Foam seals the entry points rodents use, and unlike fiberglass, it doesn’t make a cozy nest. It’s not a pest control treatment, but it removes the highway.
Our Process, Step by Step
- 1
Phone consultation and photos. Call (424) 360-2336 and Chase or a team member will ask about your symptoms: hot rooms, drafts, moisture, noise. You can text us photos of the space and we’ll give you a working range.
- 2
On-site inspection with diagnostic tools. We visit your Torrance home and use an infrared camera to find the actual air leaks and thermal bridges. You’ll see the problem spots on the screen, not hear about them secondhand.
- 3
Written price, no surprises. We hand you a written price before any work starts. It includes the exact foam type, depth, square footage, and brand. If anything changes during the job, we stop and re-quote first.
- 4
Scheduled installation at a live, trackable time. Your technician arrives at the time you see in your tracking link, not a four-hour window. We prep the space, spray, and clean up the same day on most jobs.
- 5
Photo proof and digital invoice. Before-and-after photos are sent to your phone along with your digital invoice, which you can pay from the link. Your written guarantee is attached, not promised verbally.
How Much Does Spray Foam Insulation Cost in Torrance?
A typical attic spray foam job in Torrance runs $2,800 to $7,800 depending on whether you choose open or closed cell and how much roof deck we cover. Wall retrofits land between $2,000 and $5,800 for an average home. Rim joist work is the most affordable entry point at $900 to $2,400, while full crawl space encapsulation ranges from $2,200 to $6,500. Garage applications usually cost $1,400 to $3,800.
The biggest cost factors are foam type, square footage, and access. Closed cell costs more per board foot but does double duty as a vapor barrier. Tight crawl spaces and attics with low clearance take longer and require more setup. To avoid overpaying, get a written price that specifies the exact board feet, foam type, and brand, not a lump sum with no breakdown. Our free estimates include all of that in writing before you commit to anything. Call (424) 360-2336 and we’ll walk you through it.
