Insulation in Commerce, CA
Spray foam insulation in Commerce solves a problem most cities don’t have: enormous tilt-up concrete warehouses and metal-clad distribution centers that absorb heat all day and radiate it back through the night. Our crews work on both sides of that divide, from the modest 1940s and 1950s wood-frame homes in the southwestern corner of the city to the sprawling industrial buildings along the rail corridor and freight routes. If your Commerce building is fighting a losing battle against heat gain, call (747) 837-5834 and a live person will pick up, day or night.
Why Commerce Homes Are Different
Commerce is one of the most intensely industrialized cities in Southern California. Residential housing makes up a small fraction of the building stock, which means most insulation work here is commercial and industrial: spray foam on flat warehouse rooflines, radiant barriers under corrugated metal, and interior rigid-board retrofits on concrete tilt-up walls. The small residential pockets near the southwestern edge are mostly modest wood-frame single-family homes from the 1940s through 1960s, most with little or no original wall insulation and outdated attic batts.
The climate compounds the problem. Commerce sits far enough inland that the marine layer barely reaches it. Summer highs routinely hit the low-to-mid 90s, and the city’s vast stretch of dark asphalt lots, metal roofing, and concrete creates a severe urban heat island. A warehouse that was built pre-Title 24 with no thermal envelope turns into an oven by mid-afternoon, and the heat keeps radiating from the concrete long after the sun goes down. That’s why roof and wall retrofits in Commerce tend to pay for themselves fast.
The distinctive hook here is the tilt-up concrete construction used in most post-1960s warehouses. Those concrete panels soak up heat all day, then release it into the building overnight, defeating even well-sized HVAC systems. Spraying closed-cell foam directly on the interior face of those panels is a retrofit technique that comes up constantly in Commerce, and almost never in surrounding residential cities like Bell or Maywood. It’s the single biggest difference between Commerce insulation work and what you’d find ten minutes down the 5.
Our Main Commerce Services
Two services account for most of the calls we take from Commerce homeowners: attic insulation and crawl space encapsulation. Here’s what each one looks like in this city.
Attic Insulation in Commerce
Most Commerce homes from the 1940s and 1950s have thin, settled attic batts that never delivered much R-value in the first place. With summer attic temperatures climbing well past 130°F above the roofline, that heat pours straight through the ceiling into the living space below. We inspect what’s up there, remove or top up as needed, and seal the bypasses that let conditioned air escape. Attic Insulation in Commerce covers the full process, from inspection to material selection.
Crawl Space Encapsulation & Vapor Barrier in Commerce
Older Commerce homes sit low to the ground, and the crawl spaces beneath them pull moisture from the surrounding soil. That damp air rises into the walls and floors, dragging musty odors and making the house feel clammy even when the AC is running. Encapsulation seals the crawl space with a heavy vapor barrier and closes vent openings, turning that damp zone into a clean, dry buffer under the house. Read Crawl Space Encapsulation & Vapor Barrier in Commerce for specifics on how it’s done here.

Spray Foam Insulation in Commerce
Spray foam insulation in Commerce is the workhorse solution for this city’s industrial buildings and the under-insulated homes tucked between them. When we spray closed-cell foam directly onto the interior face of a tilt-up concrete warehouse panel, we give that concrete something to hold back the heat instead of radiating it into the space. Our Spray Foam Insulation work covers everything from residential attics to large commercial rooflines, using materials from Johns Manville, Knauf, and CertainTeed.
Closed-Cell Spray Foam
Signs you need it
Concrete tilt-up walls that stay warm to the touch after dark, or an air-conditioned warehouse that can’t hold temperature past mid-afternoon.
What it costs in Commerce
Closed-cell spray foam in Commerce typically runs $2.50 to $4.50 per board foot installed, depending on depth and access.
How we do it
We prep the surface, spray the foam in lifts to the specified depth, then trim and inspect for full coverage before it cures.
Roof Deck Spray Foam
Signs you need it
A metal or flat warehouse roof that transfers punishing heat into the top of the building by mid-morning and holds it there until well after sunset.
What it costs in Commerce
Roof deck spray foam in Commerce generally falls between $2.25 and $4.00 per square foot, with larger commercial projects landing on the lower end per square foot.
How we do it
We spray the foam directly onto the underside of the roof deck, creating an air barrier and an insulating layer in one pass, then leave it exposed or cover it as code requires.
What Spray Foam Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Closed-cell spray foam (per board foot) | $2.50 - $4.50 |
| Roof deck spray foam (per sq ft) | $2.25 - $4.00 |
| Open-cell spray foam (per board foot) | $1.50 - $3.00 |
Is closed-cell foam worth the extra cost on a Commerce warehouse?
For tilt-up concrete and metal buildings in Commerce, yes. Closed-cell foam adds structural rigidity and acts as a vapor barrier, which matters when the urban heat island pushes daytime temperatures into the mid-90s for months at a time. Call (747) 837-5834 for a project-specific quote.
Can you spray foam an occupied warehouse without shutting it down?
In most cases, yes. We section off work areas and schedule spraying in phases so operations continue. The exact approach depends on the building layout and occupancy. Call (747) 837-5834 and we’ll walk you through it.
Blown-In Insulation in Commerce
Blown-in insulation in Commerce makes the most sense for the 1940s and 1950s wood-frame homes in the city’s southwestern residential pockets, where attic batts have flattened to near zero R-value. Loose-fill material settles into every corner and crevice of an old attic, covering the gaps that old batts left behind. Our Blown-In Insulation crews use Johns Manville and Knauf products, and most jobs finish in a single visit.
Blown-In Cellulose
Signs you need it
An attic with uneven, settled insulation that leaves bare spots over the ceiling, or summer cooling bills that climb every year in a Commerce home.
What it costs in Commerce
Blown-in cellulose in Commerce typically runs $1.25 to $2.50 per square foot, including material and labor.
How we do it
We run a hose into the attic and blow the cellulose to a consistent depth, fluffing and leveling as we go so coverage is uniform.
Dense-Pack Wall Insulation
Signs you need it
Exterior walls that feel cold in winter and hot in summer, a common complaint in Commerce homes built before wall insulation was standard.
What it costs in Commerce
Dense-pack wall insulation in Commerce generally falls between $2.00 and $3.50 per square foot of wall area.
How we do it
We drill small access holes, blow insulation into the wall cavities under pressure, then patch and texture the holes to match.
What Blown-In Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Blown-in cellulose (per sq ft) | $1.25 - $2.50 |
| Dense-pack wall insulation (per sq ft) | $2.00 - $3.50 |
| Blown-in top-up over existing (per sq ft) | $0.80 - $1.50 |
How much difference does blown-in insulation make in a Commerce summer?
A properly insulated attic can cut the heat transferred into your living space by half or more. In Commerce’s urban heat island, that’s the difference between an AC that cycles and one that runs nonstop. Call (747) 837-5834 for a free estimate.
Can you blow insulation over old batts?
Yes, if the existing material is dry and undamaged. We check for moisture, rodent activity, and compaction first. If it’s in decent shape, a top-up is the fastest, least expensive fix. Call (747) 837-5834 to schedule an inspection.
Radiant Barrier Installation in Commerce
Radiant barrier installation in Commerce targets the single biggest heat source for this city’s warehouses and residential roofs: direct radiant heat from the sun beating down on metal and dark shingle surfaces. By reflecting that heat before it enters the building, a radiant barrier can drop upper-floor temperatures noticeably in Commerce’s intense summer heat. Our Radiant Barrier Installation work pairs the reflective material with proper ventilation for maximum effect in this climate.
Attic Radiant Barrier
Signs you need it
Upstairs rooms or warehouse mezzanines that stay hot well into the evening even after outdoor temperatures drop, a classic Commerce urban heat island pattern.
What it costs in Commerce
Attic radiant barrier in Commerce typically runs $0.80 to $1.50 per square foot, depending on the roof pitch and access.
How we do it
We staple or adhere the reflective foil to the underside of the roof rafters, leaving an air gap that lets the material reflect heat.
Radiant Barrier Roof Deck
Signs you need it
A corrugated metal roof that radiates intense heat downward into a Commerce warehouse, making the building feel like an oven by early afternoon.
What it costs in Commerce
Radiant barrier roof deck work in Commerce generally falls between $0.70 and $1.40 per square foot for larger commercial roofs.
How we do it
We install the barrier directly under the metal roof panels or to the purlins, creating a reflective layer that stays in place for the life of the roof.
What Radiant Barrier Installation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic radiant barrier (per sq ft) | $0.80 - $1.50 |
| Radiant barrier roof deck (per sq ft) | $0.70 - $1.40 |
| Radiant barrier plus ventilation upgrade (per job) | $1,200 - $2,800 |
Does a radiant barrier actually help in Commerce’s climate?
Yes, especially on metal and dark-roofed buildings. Radiant heat is the largest heat load on a building in Commerce, and a barrier addresses it directly rather than just slowing it down. Call (747) 837-5834 to discuss your roof type.
Can you install a radiant barrier in an existing warehouse without removing the roof?
Yes, in most cases. We work from inside the building, attaching the barrier to the underside of the roof structure. The roof stays intact. Call (747) 837-5834 for an assessment.
Insulation Removal & Replacement in Commerce
Insulation removal and replacement in Commerce handles the old, failing, or contaminated material hiding in attics and walls across this city’s older building stock. In the 1940s and 1950s homes of southwestern Commerce, decades of dust, rodent activity, and settling have left insulation that hurts more than it helps. Our Insulation Removal & Replacement crews remove it cleanly and install material that meets today’s Title 24 standards, using Rockwool and CertainTeed products where specified.
Attic Insulation Removal
Signs you need it
Insulation that’s compressed, water-stained, or infested with rodent droppings and nesting material in an old Commerce home or warehouse office space.
What it costs in Commerce
Attic insulation removal in Commerce typically runs $1.00 to $2.00 per square foot, depending on depth and contamination level.
How we do it
We use a high-powered vacuum to extract the old material, bag it on site, and haul it away for proper disposal.
Insulation Replacement
Signs you need it
An attic or wall cavity where the old insulation is gone, damaged, or so thin it no longer provides any meaningful resistance to heat transfer.
What it costs in Commerce
Full insulation replacement in Commerce generally falls between $1.50 and $3.00 per square foot, including removal of the old material.
How we do it
We remove the old material, clean the surfaces, seal any bypasses, and install new insulation matched to the building’s needs.
What Insulation Removal & Replacement Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic insulation removal (per sq ft) | $1.00 - $2.00 |
| Full insulation replacement (per sq ft) | $1.50 - $3.00 |
| Contaminated insulation removal (per sq ft) | $1.50 - $2.75 |
How do I know if my Commerce attic insulation needs to be replaced or just topped up?
If it’s dry, odor-free, and only thin, a top-up works. If it’s compressed, wet, or contaminated with rodent waste, replacement is the only safe option. Call (747) 837-5834 and we’ll inspect and tell you straight.
Can you remove insulation from a Commerce warehouse office without disrupting the business?
Yes. We schedule work around your operations, contain the work area, and use negative-pressure vacuums to keep dust out of occupied spaces. Call (747) 837-5834 to plan it.
Attic Air Sealing in Commerce
Attic air sealing in Commerce addresses the invisible leaks that let conditioned air escape and outdoor heat pour in through ceilings, top plates, can lights, and other penetrations. In this city’s older homes, those leaks are often the single biggest driver of high energy bills, more than missing insulation alone. Our Attic Air Sealing work closes those gaps with foam and caulk before any new insulation goes in, because insulation without air sealing is like a jacket with no zipper.
Top Plate & Penetration Sealing
Signs you need it
Gaps where walls meet the attic floor, or around pipes, wires, and ducts, letting conditioned air pour into the attic of your Commerce home.
What it costs in Commerce
Top plate and penetration sealing in Commerce typically runs $0.75 to $1.50 per square foot of attic floor area.
How we do it
We locate every gap, fill them with expanding foam or caulk, and verify the seal before insulation goes back in place.
Attic Hatch Sealing
Signs you need it
An attic access hatch or pull-down staircase that’s poorly fitted, letting a steady stream of heat into your Commerce home all summer long.
What it costs in Commerce
Attic hatch sealing in Commerce generally runs $150 to $350 per hatch, including weatherstripping and insulation of the hatch itself.
How we do it
We weatherstrip the perimeter, add an insulated cover, and ensure the hatch closes tight against the frame.
What Attic Air Sealing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Full attic air sealing (per sq ft) | $0.75 - $1.50 |
| Attic hatch sealing (per hatch) | $150 - $350 |
| Can light and duct boot sealing (per fixture) | $25 - $60 |
How much can air sealing save on a Commerce energy bill?
Air sealing plus proper insulation typically cuts heating and cooling costs by 15 to 25 percent. In Commerce’s hot climate, the savings show up in lower summer AC use. Call (747) 837-5834 for an audit-driven estimate.
Do you air seal before or after adding insulation?
Before. Insulation alone can’t stop air movement; the leaks have to be sealed first or the new insulation underperforms from day one. Call (747) 837-5834 to schedule sealing.
Wall Insulation in Commerce
Wall insulation in Commerce is one of the most overlooked retrofits, because most of this city’s older homes were built in an era when wall cavities were left empty. Those uninsulated walls turn the entire envelope of a Commerce home into a heat exchanger, absorbing the urban heat island’s worst effects all day. Our Wall Insulation work fills those cavities without tearing out drywall, using injection foam or dense-pack methods that minimize disruption and finish clean.
Injection Foam Wall Insulation
Signs you need it
Exterior walls that are warm to the touch on summer evenings, or a Commerce home that never seems to hold its cool air regardless of thermostat setting.
What it costs in Commerce
Injection foam wall insulation in Commerce typically runs $2.50 to $4.00 per square foot of wall area.
How we do it
We drill small holes from the exterior or interior, inject the foam into the wall cavities, then patch the holes so they disappear.
Interior Wall Soundproofing
Signs you need it
A Commerce home or office space where noise from adjacent rooms or nearby industrial activity makes conversation or rest difficult.
What it costs in Commerce
Interior wall soundproofing in Commerce generally falls between $2.00 and $3.50 per square foot, depending on the material and wall thickness.
How we do it
We add sound-dampening insulation into the wall cavities, often paired with mass-loaded vinyl or resilient channels for maximum effect.
What Wall Insulation Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Injection foam wall insulation (per sq ft) | $2.50 - $4.00 |
| Interior wall soundproofing (per sq ft) | $2.00 - $3.50 |
| Exterior wall insulation retrofit (per sq ft) | $3.00 - $5.00 |
Can you insulate the walls of a Commerce home without removing the drywall?
Yes. We use injection or dense-pack methods through small access holes, which we patch afterward. The walls stay intact and the job is usually done in one visit. Call (747) 837-5834 to check your wall type.
Will wall insulation help with noise from nearby Commerce industrial traffic?
Yes, noticeably. Insulated walls block both heat and sound, which is valuable in a city where freight movement and warehouse activity are constant. Call (747) 837-5834 to discuss soundproofing options.
Attic Cleaning & Rodent Proofing in Commerce
Attic cleaning and rodent proofing in Commerce matters because this city’s mix of older wood-frame homes and constant freight traffic means attics are magnets for rodents looking for quiet nesting space. Once rodents get in, they shred insulation, leave droppings, and chew on wiring. Our Attic Cleaning & Rodent Proofing teams remove the mess, sanitize the space, and seal every entry point so the problem doesn’t come back. The 90-Day Done Right Promise applies to every job.
Attic Cleanout
Signs you need it
Visible droppings, nesting material, or chewed insulation in the attic of your Commerce home, or a musty, animal odor that gets worse in summer.
What it costs in Commerce
Attic cleanout in Commerce typically runs $500 to $1,200, depending on the attic size and the severity of contamination.
How we do it
We remove all contaminated insulation and debris by vacuum, bag it for disposal, and prep the attic for sanitizing.
Rodent Proofing & Exclusion
Signs you need it
Gaps around roof edges, vents, utility lines, or eaves where rodents can squeeze into your Commerce attic or warehouse mezzanine.
What it costs in Commerce
Rodent proofing and exclusion in Commerce generally runs $400 to $900 for a typical residential attic, depending on how many entry points need sealing.
How we do it
We identify every entry point, seal them with steel mesh, foam, and hardware cloth, and verify the attic is secure before we finish.
What Attic Cleaning & Rodent Proofing Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Attic cleanout (per job) | $500 - $1,200 |
| Rodent proofing and exclusion (per job) | $400 - $900 |
| Attic sanitizing and decontamination (per job) | $300 - $700 |
How fast can you clean a rodent-infested attic in Commerce?
Most cleanouts finish in a single visit, usually four to six hours depending on the attic size. Sanitizing and exclusion may require a second short visit. Call (747) 837-5834 and we’ll give you a firm timeline.
Do you guarantee the rodents won’t come back?
Our 90-Day Done Right Promise covers the exclusion work. If rodents re-enter through any gap we sealed, we come back and fix it at no charge. Call (747) 837-5834 to schedule an inspection.
Home Energy Audit in Commerce
A home energy audit in Commerce is the diagnostic starting point that makes every other insulation service smarter and more targeted. Instead of guessing, we measure where heat is entering and conditioned air is leaving, then tell you exactly which improvements will pay for themselves fastest. Our Home Energy Audit uses blower door testing and thermal imaging to map the building’s weak points, which is especially valuable in a climate like Commerce’s where the urban heat island distorts normal assumptions about heat gain.
Blower Door Test
Signs you need it
High energy bills in your Commerce home or warehouse office that don’t respond to thermostat adjustments, suggesting significant air leakage somewhere in the envelope.
What it costs in Commerce
A blower door test as part of a full energy audit in Commerce typically runs $250 to $500.
How we do it
We mount a calibrated fan in an exterior door frame, depressurize the space, and measure exactly how much air leaks through the building envelope.
Thermal Imaging Inspection
Signs you need it
Uneven temperatures between rooms, or visible condensation or hot spots on walls and ceilings in a Commerce building.
What it costs in Commerce
A thermal imaging inspection in Commerce generally falls between $200 and $400 when bundled with a full audit.
How we do it
We scan every wall, ceiling, and floor with an infrared camera to find missing insulation, air leaks, and thermal bridges.
What Home Energy Audit Costs in Commerce
| Item | Typical range in Commerce |
|---|---|
| Blower door test (per test) | $250 - $500 |
| Thermal imaging inspection (per inspection) | $200 - $400 |
| Full home energy audit (per audit) | $400 - $900 |
Is a home energy audit worth it before insulating a Commerce home?
Yes. It tells you exactly where the biggest losses are, so you spend money on the fix that matters most, not on a one-size-fits-all guess. Call (747) 837-5834 to book one.
Can you audit a commercial warehouse in Commerce, not just a house?
Yes. We audit residential and commercial buildings, including warehouse spaces and offices. The same diagnostic tools apply. Call (747) 837-5834 to discuss your building.

What Commerce Customers Say
"Crawl space smelled musty and the floors were cold. Full encapsulation with the thick liner taped at every seam, and a dehumidifier sized for the space. The hygrometer they left reads 48 percent now instead of the 70s."
- Elena Vasquez"Radiant barrier stapled to the rafters plus new baffles at the soffits. Attic temperature dropped enough that the AC runs noticeably less in the afternoon. Crew was in and out in a day and left the garage cleaner than they found it."
- Sam Kessler"They did the energy audit first - blower door and thermal camera - and showed me exactly where the house was leaking before selling me anything. The fix ended up being air sealing plus a modest attic top-up, not the full replacement another company pushed."
- Grace Nakamura
