Hollywood’s housing stock is unlike anywhere else in South Florida. The 1920s-1940s Spanish Colonial Revival bungalows, Craftsman homes, and early apartment courts that define this neighborhood were built long before forced-air HVAC existed. When systems were retrofitted decades later, duct runs were threaded through original plaster-and-lathe wall cavities in layouts no standard manual ever contemplated. That history lives in your walls. Our Duct Repair & Sealing team knows how to work with it, not against it.
Why Bellows Air Duct & Vent Co. Is Hollywood’s Preferred Duct Repair & Sealing Company
We’ve been in business since 1984 - over 42 years - and we’ve learned that Hollywood homeowners don’t want the lowest coupon. They’ve been burned by that before. They want the job done right, with a number on the phone that matches the number on the invoice, and a guarantee that means something if something goes wrong.
Our 90-Day Done Right Promise is stamped on every job. If it’s not right, we make it right. No paperwork, no arguing. We also camera-inspect every duct system before and after work, so you see what we see - not just take our word for it. Pricing is disclosed upfront before a single tool is lifted. No bait coupons, no price changes at the door.
Calls are answered by a live person, 24 hours a day. Not voicemail. Not an app. Our technicians are background-checked and uniformed, and most jobs are completed in a single visit. That’s the square deal we’ve built our name on.
We know Hollywood’s streets - from Franklin Avenue to the apartment courts near Hollywood Boulevard - and we understand how the hillside canyon winds that funnel through 90028 stress duct systems differently than flatland neighborhoods to the east. That local knowledge matters when you’re deciding whether to patch a 70-year-old flex run or replace it entirely.
Our Duct Repair & Sealing Services in Hollywood
Duct Sealing
Leaky ducts in Hollywood’s retrofitted bungalows often lose 20-30% of conditioned air before it ever reaches a register. We seal every joint, boot, and penetration with mastic sealant - the professional standard that outlasts any tape - and pressure-test the system to verify results. In Hollywood’s dry climate, without humidity to clump and settle dust, fine particulates circulate constantly through any gap. A sealed system stops that waste and keeps your air where it belongs.
Flex Duct Repair
Flex duct is common in Hollywood’s 1950s-1970s apartment complexes, and it fails predictably: torn inner liners, crushed runs, and canvas collars that separate from register boots. We recently sealed a flex duct run in a 1947 courtyard apartment off Franklin Avenue, where the old canvas collar had come loose from the register boot, spilling conditioned air into the plaster-and-lathe wall cavity. We re-attached it with a stainless steel clamp and applied mastic sealant to every joint, and the tenant’s utility bill dropped by nearly ten percent the next month. Flex duct repair in Hollywood typically runs $180-$340 per run, depending on access and length.
Metal Duct Repair
Original sheet-metal ductwork in Hollywood’s pre-1960 buildings often shows rust at seams, separated drive cleats, or failed fiberglass lining that’s shedding particles into the airstream. We repair metal runs with proper mechanical fastening and seal with mastic, never duct tape. Where original asbestos wrap is present, we carry sampling kits as standard equipment and halt work pending certified abatement - a protocol rarely needed in newer-stock neighborhoods just a few miles away in Burbank or Culver City.
Duct Insulation
Uninsulated or deteriorated duct insulation in Hollywood’s hillside homes wastes energy every summer when attic temperatures climb. We install new insulation wraps rated for local conditions, with particular attention to runs that pass through unconditioned spaces. For buildings with original 1940s-1950s insulation that may contain asbestos, we coordinate with certified abatement contractors before any new work begins. Duct insulation replacement in Hollywood typically ranges from $450-$890 for a standard residential system.
Mastic Sealant Application
Mastic is the only sealant we trust for Hollywood’s older duct systems. Unlike tape, which dries and fails within years in our dry heat, mastic remains flexible and maintains its bond. We brush or spray mastic at every joint, seam, and penetration, then verify with visual inspection and pressure testing. Mastic sealing of an average Hollywood home’s duct system runs $350-$650.

Common Duct Repair & Sealing Problems We See in Hollywood Homes
- Old duct tape and deteriorating canvas collars fail silently, leaking cooled air into wall cavities, especially in 1920s-1940s retrofitted bungalows where original plaster-and-lathe construction hides the damage until utility bills spike or rooms never reach temperature.
- Asbestos-wrapped ducts from the 1940s-1950s are often disturbed by well-meaning DIYers, leading to hazardous fibers being blown into living spaces. In Hollywood’s 90028, this is common enough that reputable operators carry sampling kits as standard equipment and know to halt cleaning pending abatement.
- Nesting rodents and birds in aging apartment attic or crawlspace ducts create gaps and holes that are easy to miss if the run isn’t fully inspected from the outside. We camera-inspect every system to catch damage that a register-only check would never reveal.
- Santa Ana wind events deliver concentrated dust and debris through hillside canyons directly into HVAC intakes, accelerating wear on seals and filters and forcing systems to run longer with compromised ductwork. Sealed systems withstand these loads far better than leaky ones.

FAQs - Duct Repair & Sealing in Hollywood
Yes, but we inspect first for asbestos. In Hollywood’s 90028, pre-1960 apartment buildings often still have original duct insulation and register boot seals that may contain asbestos. This is common enough that our crews carry sampling kits as standard gear and know to stop work pending abatement. Once cleared, we can seal and repair normally. Call (844) 685-6342 to schedule a camera inspection.
Mastic sealant at every joint, boot, and penetration stops the infiltration that wind-driven dust exploits. In Hollywood’s canyon-funnelled wind patterns, even small gaps at the air handler or return plenum pull in extraordinary particulate loads. A fully mastic-sealed system, pressure-tested after application, is the most effective defense. Whole-system mastic sealing in Hollywood typically runs $350-$650. Call for a free estimate.
Yes. We reattach flex duct with stainless steel clamps and seal every joint with mastic. A typical flex duct repair in Hollywood runs $180-$340 per run, and most are completed in a single visit. We’ll camera-inspect the full run to check for collateral damage from the loose section. Call (844) 685-6342 to schedule.
Yes. Canvas-wrapped ducts from the 1940s-1950s in Hollywood frequently contain asbestos. We carry sampling kits and will test before disturbing any material. If asbestos is present, we halt work and coordinate certified abatement. This protocol is standard for our Hollywood crews but rarely needed in newer neighborhoods nearby. Never disturb suspected asbestos yourself. Call us for a safe inspection.
Camera inspection reveals the difference. Poor original installation in Hollywood’s retrofitted bungalows shows as unsupported sagging, crushed flex, or boots never properly sealed to registers. Wear and tear shows as tape degradation, rust, or rodent damage. Often it’s both. We show you the footage, explain what’s original deficiency and what’s age-related, and quote repair accordingly. Estimates are free. Call (844) 685-6342.
