Fast, Reliable Spray Foam Insulation Across West Hollywood
Spray foam insulation in West Hollywood typically costs $2,800 – $6,500 for a full attic or roof-deck retrofit, depending on whether you’re sealing a 1920s bungalow in the Norma Triangle or a 1960s flat-roofed apartment near Santa Monica Boulevard. We get calls from West Hollywood homeowners and property managers every week who are dealing with the same issues: west-facing walls that turn rooms into ovens during Santa Ana events, flat roofs with zero attic access, and old plaster walls that were never insulated when they were built. Our crews know the 90069 housing stock inside and out, and we can usually be on-site within 48 hours. Call (877) 352-4780 for a free estimate.
Why Aliso Viejo Insulation Co Is West Hollywood’s Preferred Spray Foam Insulation Company
West Hollywood is a different animal from the rest of Los Angeles County. Most of our work here happens inside occupied, rent-stabilized buildings, which means we’ve learned to plan jobs in short, tenant-friendly windows and to communicate clearly with property managers who answer to the city’s rent stabilization office. We’ve sprayed roofs on fourplexes off Westbourne Drive, sealed rim joists in hillside homes above Sunset, and retrofitted garages in the flats between Santa Monica and Melrose. The work is always precise.
Nate Calloway, our owner, built this company around a simple idea: recommend the material that matches the building, not the material that’s easiest to sell. That’s why we carry both Icynene and Demilec spray foam systems, and why we’re equally comfortable specifying Rockwool mineral wool or Johns Manville fiberglass when the job calls for it. Homeowners in West Hollywood who call us get an honest assessment of what their particular building needs. That approach has earned us a strong local reputation among both single-family owners and multi-family property managers. We don’t pad quotes, and we don’t cut corners on fire-safety details that West Hollywood inspectors actually check.
Crawl Space Spray Foam Insulation in West Hollywood
Crawl Space Spray Foam Insulation in West Hollywood is a retrofit we handle regularly in the older bungalows and Spanish Colonial homes scattered through the Norma Triangle and the streets below the hills. These homes, many built in the 1920s and 1930s, sit over shallow crawl spaces that were rarely sealed or insulated. Open-cell spray foam works well here because it seals the floor assembly from below, stops the draft that creeps up through old hardwood floors, and helps keep dust and pests out of the living space. A typical crawl space job in West Hollywood runs $1,800 – $3,400 for a 1,200-square-foot home, depending on access clearance and whether we need to remove old fiberglass batts first.
Rim joist sealing for older foundations
The rim joist, where the floor framing meets the foundation wall, is one of the biggest air-leakage points in any older West Hollywood home. Closed-cell foam, typically two inches, seals that gap and adds real structural rigidity. Homeowners notice the difference immediately in floor comfort, especially in bedrooms over the crawl space.
When your crawl space is too tight for batts
Some of these older homes have crawl spaces with barely 18 inches of clearance. Installing fiberglass batts in a space like that is miserable work that rarely gets done well. Spray foam applied by our crew reaches every corner, including areas a batt installer could never access. That’s why we recommend foam for tight, shallow West Hollywood crawl spaces nearly every time.
Garage Spray Foam Insulation in West Hollywood
Garage Spray Foam Insulation in West Hollywood is a smart move for anyone who uses their garage as more than a parking spot. A lot of 90069 homes have attached garages that share a wall or ceiling with living space, and those garages are almost always uninsulated. The result is a room that turns into a radiant-heat trap in summer, and cold air that migrates into adjacent bedrooms in winter. We spray open-cell foam on garage ceilings and shared walls, which seals the space and cuts both heat gain and noise transfer. A typical single-car garage spray foam job in West Hollywood runs $1,200 – $2,400, and it’s usually finished in half a day.
Garage ceiling and shared-wall sealing
When a garage sits directly below a bedroom or living room, the floor assembly between them is a giant uninsulated void. Closed-cell foam on the garage ceiling stops the heat from rising into the living space above and keeps car exhaust odors from seeping through gaps. Homeowners in hillside West Hollywood properties, where garages are often carved into the slope, especially benefit from this because those structures are partly earth-sheltered and prone to damp air.
Converting your West Hollywood garage into usable space
If you’re planning to turn a garage into a home office, gym, or studio, spray foam is the fastest way to condition the space. We pair the foam with a thermal barrier as required by code, and the whole job is typically done in one visit. Property managers doing this in West Hollywood’s rental buildings like that we can seal a garage without making tenants move cars for more than a day.
Trusted Brands We Service in West Hollywood
We’re authorized to install products from eight nationally recognized manufacturers, and we keep a stocked inventory for West Hollywood jobs, so we don’t lose time waiting on shipments. For spray foam specifically, we use Icynene and Demilec, two of the industry’s leading open-cell and closed-cell systems. When a job calls for something else, like Rockwool mineral wool for fire resistance in multi-family walls or Johns Manville fiberglass for a standard attic, we spec and install that too. The point is matching the material to the building. If you own a 90069 property and want an unbiased recommendation on what belongs in your walls or roof, call us. You won’t get a one-brand sales pitch.
Common Spray Foam Insulation Problems We See in West Hollywood Homes
- Spray foam over knob-and-tube wiring in 1920s plaster walls. This is a real fire hazard, and it fails city inspection every time. In older Norma Triangle homes, we check for live knob-and-tube before any foam goes in, and we’ll tell you if the wiring needs to be addressed first.
- Foam on a flat roof deck without fixing ponding water first. If a 1960s apartment roof already has standing water or trapped moisture, spraying foam over it just seals the problem inside. We inspect the deck and address drainage issues before insulating.
- High-expansion foam in shallow wall cavities of older bungalows. Some contractors use whatever foam is on the truck, and in a 1930s West Hollywood wall with 2×4 framing and old plaster, that can bow the wall and crack interior finishes. We use the right expansion rate for the cavity depth.
- Ignoring the rent-stabilization timeline on tenant-occupied units. You can’t just spray a top-floor apartment whenever it’s convenient. We plan around tenant schedules and the city’s rules so the job gets done without complaints or fines.

FAQs About Spray Foam Insulation in West Hollywood
Yes, and we do it regularly. The key is phasing the work unit-by-unit, usually one unit per day, so tenants only have to vacate for a few hours at a time. We coordinate the schedule directly with the property manager and work within any rent-stabilization requirements on unit downtime. Call (877) 352-4780 and we’ll walk you through a phased plan for your building.
The best approach is closed-cell foam applied directly to the underside of the roof sheathing, then covered with a thermal barrier. This creates a sealed, insulated roof assembly without needing attic access, and it’s exactly what we did for a fourplex on Westbourne Drive in the Norma Triangle. The top-floor units stayed noticeably cooler through the next Santa Ana event. Give us a call at (877) 352-4780 and we can evaluate your roof deck.
Yes, absolutely. If your home was built in the 1920s or 1930s and still has knob-and-tube wiring, spraying foam directly over it is a fire hazard and will fail inspection in West Hollywood. We check for this before any foam goes in and we’ll tell you exactly what needs to happen first. Estimates are free, so call us at (877) 352-4780 to schedule an inspection.
It affects the timeline by requiring that tenant displacement, even for a few hours, be planned and communicated properly. Property owners have to work within the rules on unit downtime, and we’ve done enough of these jobs to keep things moving without triggering complaints. The insulation work itself doesn’t stop, the scheduling just gets tighter, which is where experience with West Hollywood buildings really matters. Call (877) 352-4780 if you manage a rent-stabilized property and need a contractor who understands the process.
Yes, spray foam is a great fit for West Hollywood garages, and it’s especially useful on hillside properties where garages are built into the slope and tend to hold damp, warm air. Closed-cell foam on the ceiling and shared walls seals the space and keeps heat and car odors from migrating into the house. A typical single-car garage job is done in one visit. Call (877) 352-4780 for a quote.
