Fast, Reliable Duct Repair & Sealing Across West Hollywood
Duct repair and sealing in West Hollywood, FL typically runs $280–$650 for most residential jobs, with same-day diagnostics available throughout the 33021 ZIP code. If your home was built during the 1950s–1970s South Florida boom, there’s a strong chance your flex ductwork is already past its functional lifespan — crumbled liners, separated joints, and attic heat damage that standard cleaning alone won’t fix. We’re local to Broward County and regularly on Johnson Street, Stirling Road, and the neighborhoods around West Hollywood’s concrete-block ranch corridors. Call (833) 628-3661 and we’ll get someone out to assess what’s actually happening in your attic.
Why Apex Air Duct Cleaning Service Miami Is West Hollywood’s Preferred Duct Repair & Sealing Company
We’ve built our reputation in West Hollywood by showing up personally and doing the work ourselves — owner Michael Brown is the lead technician on every job, not a rotating subcontractor you’ll never see again. Across 867 verified reviews, we’ve maintained a 4.9-star rating, and a significant portion of those jobs came from repeat customers right here in unincorporated Broward County who’d had enough of franchise crews that couldn’t diagnose beyond “your ducts are dirty.”
Our Duct Repair & Sealing team knows the local housing stock cold: the CBS slab-foundation ranches from the 1960s and 70s, the tight attic clearances where temperatures exceed 140°F, and the specific failure patterns that develop when flex duct liners bake for decades in that environment. We respond to West Hollywood calls with the same urgency we bring to Miami — typically same-day or next-morning availability — because we understand that in a climate where your AC runs 11 months a year, a compromised duct system isn’t an inconvenience, it’s an air quality emergency.
We carry professional-grade Rotobrush and Nikro equipment, the same rotary brush and negative-pressure vacuum systems used by commercial restoration contractors. That matters in West Hollywood, where the debris load in failed ducts often exceeds what consumer-grade equipment can safely extract. From cleaning to repair to sanitizing — handled in one visit, by one accountable technician.
Our Duct Repair & Sealing Services in West Hollywood
Flex Duct Repair
West Hollywood’s housing stock is dominated by post-WWII concrete-block ranch homes, many still running original or early-replacement flexible ductwork that has spent decades in those sweltering attics. The inner liner — the smooth surface that actually carries conditioned air — degrades under sustained heat exposure until it crumbles into particles that blow straight into your living space. We recently serviced a home on Johnson Street where the 1960s flex duct had collapsed inner liners spewing foam particles into vents. Using Rotobrush agitation and mastic sealant, we removed 6 lbs of debris and sealed all joints, restoring airflow and halting recontamination. In West Hollywood, this failure mode is almost routine; just a few miles west in Pembroke Pines, we rarely see it.
Duct Sealing with Mastic Sealant
Joint separations in aged mastic tape are epidemic in West Hollywood’s older stock. The original tape adhesives dry out after 40–60 years of thermal cycling, creating gaps that leak conditioned air into attics and draw humid, unfiltered air back into your system. We apply modern mastic sealant — a fiber-reinforced compound that remains flexible and bonds to both metal and flex duct surfaces — to every joint, transition, and penetration point. In West Hollywood’s tight townhome crawlspaces and low-clearance attics, we use extension tools and LED inspection cameras to reach areas that standard brush-and-vac crews miss entirely.
Metal Duct Repair
Not every West Hollywood home runs flex. Some 1950s–60s ranches and a handful of commercial buildings near Stirling Road still have galvanized steel ductwork, and those systems fail differently — rust-through at low points where condensation pools, separated seams from thermal expansion, and disconnected collars at the air handler. We repair metal ducts with proper sheet-metal patching, mechanical fastening, and sealed transitions back to flex runs where retrofits were added. Our Nikro negative-pressure system contains debris during cutting and grinding, so we’re not coating your attic insulation with metal shavings.
Duct Insulation Replacement
When flex duct insulation breaks down in West Hollywood’s humid attics, it does more than lose R-value — it becomes a moisture sponge that breeds mold and biofilm. We strip compromised insulation, treat the underlying duct for microbial growth, and install new fiberglass or closed-cell insulation with proper vapor barriers. This is especially critical in West Hollywood, where humidity regularly stays above 80% and near-constant AC operation creates ideal conditions for colonization inside older ductwork. Annual cleaning without insulation replacement in these conditions is a temporary fix at best.

Trusted Brands We Service in West Hollywood
We work with Honeywell, Aprilaire, and Guardsman air quality components — the same brands installed in West Hollywood homes by HVAC contractors who understand this market’s demands. We stock common replacement parts and sealing materials locally, so we’re not ordering mastic compound or flex duct transitions from a warehouse three counties away while your attic stays open. For West Hollywood customers, that means faster turnaround from diagnosis to sealed, tested system. Our Rotobrush and Nikro equipment is maintained to manufacturer spec, because in 11 years of focused, single-trade experience, we’ve learned that tool reliability directly determines result reliability.
Common Duct Repair & Sealing Problems We See in West Hollywood Homes
- Crumbled flex duct inner liners — The signature West Hollywood failure. Decades of 140°F attic heat reduce the inner liner to debris that re-contaminates living spaces with every AC cycle. Standard cleaning removes surface buildup but can’t restore a liner that’s already disintegrated; partial or full duct replacement is the only durable fix.
- Joint separations in aged mastic tape — Original tape from 1960s–70s installations has long since dried and lost adhesion, creating massive air leaks that waste energy and create pressure imbalances. In West Hollywood’s tight townhome crawlspaces, these separations are often inaccessible without proper tools and experience.
- Mold colonization in sagging ducts — When flex duct loses its structural integrity and sags, low points collect condensation that supports persistent mold and biofilm growth. Cleaning alone won’t solve this; the sag must be corrected, damaged sections replaced, and insulation upgraded to prevent recurrence.
- Insulation breakdown trapping debris and moisture — Compressed, torn, or water-damaged insulation loses its thermal barrier function and becomes a debris source itself. In West Hollywood’s near-constant cooling season, this drives up energy bills and degrades indoor air quality simultaneously.

What moves you within these ranges? Accessibility — tight West Hollywood attics with limited clearance take longer. Extent of liner damage — a single compromised run versus a whole-house replacement. And whether we’re addressing active mold, which requires containment and antimicrobial treatment before sealing can begin. We don’t quote over the phone for repair work; we inspect, show you what we’ve found (usually with camera footage from inside the duct), and give you an upfront price before any work starts. Estimates are free. Call (833) 628-3661 to schedule.

FAQs — Duct Repair & Sealing in West Hollywood
Look for fine debris — white or gray particles resembling coarse dust — blowing from your vents when the AC first cycles on, or a persistent “dirty sock” odor that doesn’t resolve with filter changes. We’ll confirm with a camera inspection; if the liner is compromised, we’ll show you the footage and explain whether spot repair or full replacement makes sense. Call (833) 628-3661 for a free diagnostic — estimates are free.
Townhomes here often have duct runs through shared wall cavities and tighter crawlspaces with limited access points, meaning leaks in one unit can pressure-balance into adjacent spaces and repairs require more precise containment. We use smaller-diameter inspection tools and flexible mastic application equipment designed for these constraints. Call (833) 628-3661 — we’ll assess your specific layout and give you an exact quote.
Sealing alone won’t eliminate mold smell if active colonization is present — but it will stop the humid, unfiltered attic air that’s feeding it. We typically pair sealing with antimicrobial treatment and, if the duct is sagging, structural repair to eliminate condensation collection points. In West Hollywood’s humidity, the complete approach is what actually works long-term. Call (833) 628-3661 and we’ll test for both leaks and microbial load.
We repair both. Metal ductwork in West Hollywood is less common but appears in some 1950s ranches and commercial spaces near Stirling Road — we patch rust-through, reseam separated joints, and transition properly to flex where retrofits were added. Our Nikro system contains debris during metalwork, and we pressure-test every repair before leaving. Call (833) 628-3661 to discuss your specific system type.
Most complete sealing jobs on a 1,200–1,600 square foot ranch finish in 4–6 hours; if we’re replacing multiple flex duct runs due to crumbled liners, expect a full day. We work methodically — every joint sealed, every repair pressure-tested, every access point restored — because in 11 years we’ve learned that rushing this work creates callbacks. We don’t do callbacks. Call (833) 628-3661 to schedule; we’ll give you a firm time estimate after inspection.
Ready to fix what’s actually wrong with your ductwork? Don’t settle for another cleaning that ignores the underlying damage.
