We’ve worked the tight grid of West Hollywood for decades. The 1.9-square-mile city, with its concentration of 1950s-1970s apartment buildings along corridors like Sunset Boulevard and Santa Monica Boulevard, presents duct challenges you don’t find in suburban single-family markets. Shared air-handling systems, minimal clearance in utility closets, and alley-access constraints mean repairs require technicians who know how to work efficiently in dense conditions without disrupting multiple households. That’s the work our Duct Repair & Sealing team does every day.
Why Bellows Air Duct & Vent Co. Is West Hollywood’s Preferred Duct Repair & Sealing Company

West Hollywood customers call us back because we understand their buildings. The two- to four-story apartment complexes on streets like Laurel Avenue and Sweetzer Avenue, many with original galvanized ductwork and degraded fiberglass insulation, need repair approaches that respect both the vintage construction and the fact that six to twelve units share a single system. We don’t treat a WeHo job like a standalone house call.
Our response time to West Hollywood averages under an hour during business hours, with emergency calls answered by a live person 24 hours a day. No voicemail, no app. Background-checked, uniformed technicians arrive with camera inspection equipment and professional-grade tools from Nikro and Abatement Technologies, ready to complete most repairs in a single visit.
We’re the square-deal alternative to operators who advertise a low coupon then change the price at the door. Our upfront pricing is disclosed before a single tool is lifted. The number on the phone is the number on the invoice.
Our Duct Repair & Sealing Services in West Hollywood
Duct Sealing
Leaky ducts in West Hollywood’s older apartment buildings don’t just waste energy; they redistribute conditioned air unevenly across multiple units, creating hot spots and cold spots that generate tenant complaints. Our sealing process starts with a camera inspection to map the full system, then we seal accessible joints and seams with mastic sealant and mechanical fasteners, not foil tape that fails within months on vibrating 1950s metal. We recently completed a sealing job on Havenhurst Drive where a torn flex duct junction was leaking into an unsealed ceiling void; we cut out the damaged section, replaced it with insulated flex duct, and sealed all connections with mastic and foil tape, restoring balanced airflow to all six units served by that system.
Flex Duct Repair
Flex duct runs in West Hollywood’s older buildings have often collapsed, torn at hanger points, or degraded from decades of vibration and heat cycling. We replace damaged sections with properly sized insulated flex duct, secure them with tension straps at code-required intervals, and seal every connection. In buildings backing up toward Laurel Canyon, we frequently find flex duct contaminated with charcoal-black soot banded between layers of ordinary dust, a record of successive fire seasons that requires removal rather than cleaning.
Metal Duct Repair
Original galvanized steel ductwork in pre-1970s West Hollywood buildings suffers from seam separation, rust-through at low points, and vibration fatigue at supports. We repair with 26-gauge galvanized patches, mechanical fasteners, and two coats of mastic, or recommend sectional replacement when corrosion is too advanced. Every repair is photographed before and after for your records.
Duct Insulation
Degraded fiberglass duct wrap in West Hollywood’s vintage buildings creates both energy loss and indoor air quality concerns. We install new foil-faced fiberglass insulation or closed-cell duct liner where appropriate, with particular attention to rooftop and exterior chase runs exposed to the summer heat and winter Santa Ana winds.

Trusted Brands We Service in West Hollywood
We carry parts and materials from Honeywell and Aprilaire for control and filtration components, and stock Nikro and Abatement Technologies equipment for inspection and remediation work. For West Hollywood customers, this means faster turnaround on repairs that require specific components, fewer return trips, and systems restored to manufacturer specifications. Our technicians specify the right material for each job, whether that’s mastic sealant rated for high-velocity systems or insulated flex duct for rooftop exposed runs on north-side buildings near the canyon.
Common Duct Repair & Sealing Problems We See in West Hollywood Homes
- Foil tape failure on vibrating metal ducts. Previous technicians used foil tape only on 1950s galvanized seams. The vibration of shared air-handling systems shakes it loose within months. We use mastic and mechanical fasteners for permanent sealing.
- Asbestos-containing duct wrap overlooked. Pre-1970s buildings throughout West Hollywood retain original duct insulation that may contain asbestos. Disturbing it without abatement protocol creates legal liability and health hazards. We identify suspect materials and coordinate proper handling before sealing work begins.
- Hidden leaks in shared chases. Sealing visible joints while ignoring leaks inside wall and ceiling chases leaves neighboring units with poor airflow and drives up energy costs for the entire building. Our camera inspection maps the full system before we start.
- Post-wildfire soot accumulation. The Hollywood Hills and Laurel Canyon brush land sit immediately north of West Hollywood. During October-December Santa Ana wind events, smoke and carbonized ash concentrate along the Sunset Strip corridor and are drawn directly into roof-mounted HVAC intakes. We find stratified soot layers in ductwork that cleaning alone cannot address, requiring sectional repair and resealing.
