Fast, Reliable Duct Repair & Sealing Across Kendale Lakes
Duct repair and sealing in Kendale Lakes, FL typically costs between $280 and $850 depending on the scope, and most jobs are completed in a single visit. If your home was built during the 1970s or early 1980s — which describes most of Kendale Lakes — your original ductwork has been running nonstop through decades of South Florida humidity, and it’s likely showing its age.
We’re based in Miami and regularly work the western edge of Miami-Dade, including the 33183 ZIP code and the neighborhoods off SW 88th Street and SW 107th Avenue. Our Duct Repair & Sealing team knows these homes: the concrete-block construction, the attic-run duct systems, the flat roofs that trap heat, and the Everglades moisture that never really lets up. When you call (833) 628-3661, you’re reaching Michael Brown directly — owner and lead technician, not a dispatcher sending out whoever’s available that day.
Why Apex Air Duct Cleaning Service Miami Is Kendale Lakes’s Preferred Duct Repair & Sealing Company
Kendale Lakes homeowners have left us 867 verified reviews across our service area, with a 4.9-star average that reflects consistent, repeatable work. That volume matters more than a handful of cherry-picked testimonials — it means we’ve handled the specific duct failures this community faces, and we’ve done it hundreds of times.
We’re owner-operated and owner-present. Michael Brown shows up with the tools, runs the inspection, and oversees the repair. No rotating subcontractors, no franchise crews where the person you spoke with isn’t the person in your attic. In 11 years focused exclusively on air duct and HVAC cleaning, we’ve built a reputation on one trade done deeply — not duct cleaning as an upsell from a general handyman operation.
Our response time to Kendale Lakes is typically same-day or next-day, since we’re already working the western Miami-Dade corridor regularly. We carry professional-grade Rotobrush and Nikro equipment — the rotary brush and negative-pressure vacuum systems used by commercial restoration contractors — and we stock mastic sealant, insulated flex duct, and replacement duct board sections so most repairs don’t require a return trip.
We know the difference between a home near the Kendale Lakes Country Club and one off SW 137th Avenue, and we know both are dealing with the same underlying issue: original ductwork that has absorbed 40-plus years of condensation in essentially tropical attic conditions.
Our Duct Repair & Sealing Services in Kendale Lakes
Duct Sealing
Sealing is the foundation of every repair we do in Kendale Lakes. The metal duct seams in these homes — especially in crawl spaces and attic runs — corrode from continuous humidity exposure, oxidizing through until conditioned air leaks into spaces that don’t need cooling. We seal with mastic compound, not duct tape, because mastic remains flexible and airtight through Miami’s heat cycles while tape dries and fails. A typical duct sealing job in Kendale Lakes runs $280–$450 for partial-system work, or $550–$850 for full-system sealing in a larger home.
Flex Duct Repair
First-generation flex duct in Kendale Lakes homes has a predictable failure pattern: the connections at the plenum collar collapse under the weight of attic insulation, creating major air leaks and system imbalance. The insulation itself compresses and loses R-value. On a recent job in a planned community off SW 126th Avenue, we found a flex duct run that had disintegrated at the plenum collar, dumping cooled air into the attic. We replaced it with new insulated flex and sealed every joint with mastic, restoring full airflow to the master bedroom. Flex duct repair in Kendale Lakes typically ranges from $180–$340 per run, with most homes needing 2–4 runs addressed.
Metal Duct Repair
Where metal ductwork still exists in Kendale Lakes homes, we find corrosion at seams and joints that has progressed beyond what sealing alone can address. We cut out failed sections, fabricate replacements, and integrate them with the existing system using proper transitions. Metal duct repair in this market runs $320–$580 depending on accessibility and the extent of corrosion. Homes near the western edge of Kendale Lakes, closer to the Everglades, tend to show more advanced corrosion due to higher sustained humidity.
Duct Insulation
Attic temperatures in Kendale Lakes flat-roof homes regularly exceed 130°F, and uninsulated or degraded duct insulation costs you measurable efficiency. We install new foil-faced fiberglass insulation or replace collapsed flex duct with properly insulated runs. Duct insulation work in Kendale Lakes typically falls between $220–$480 for targeted sections, or $650–$950 for full-system re-insulation in larger homes. Given that A/C systems here run 10–11 months annually, the payback period on proper insulation is shorter than in virtually any other U.S. market.

Trusted Brands We Service in Kendale Lakes
We work with Honeywell, Aprilaire, and Abatement Technologies air quality components — the same brands specified by commercial HVAC contractors — and we stock Guardsman antimicrobial treatments for post-repair application. For Kendale Lakes customers, this means we don’t order parts after diagnosing your problem; we carry the inventory to complete most repairs in one visit. Our Rotobrush and Nikro systems are the same units used in commercial restoration, not consumer-grade shop vacs adapted for duct work. When you’re already dealing with 1970s-era duct failure, the last thing you need is equipment that isn’t up to the job.
Common Duct Repair & Sealing Problems We See in Kendale Lakes Homes
- Fiberglass duct board liner delamination. The original fiberglass duct board in Kendale Lakes homes has softened and delaminated from decades of condensation, making duct replacement a frequent on-the-spot recommendation rather than a simple repair. The material itself becomes the contamination source.
- Flex duct collapse at plenum connections. Weighted down by attic insulation and weakened by age, flex duct connections separate from collars, dumping conditioned air into the attic and starving the rooms below. We find this in roughly two-thirds of the Kendale Lakes homes we inspect.
- Metal duct seam corrosion in humid crawl spaces. Continuous humidity oxidizes metal seams from the outside in, creating pinhole leaks that compound over years. Kendale Lakes’s position near the Everglades accelerates this compared to eastern Miami-Dade.
- Collapsed or compressed duct insulation. Attic heat and moisture degrade insulation over decades, leaving ductwork unprotected and forcing your A/C to overcome thermal losses it wasn’t designed for.

FAQs — Duct Repair & Sealing in Kendale Lakes
Because ductwork is out of sight and often out of mind until it fails completely. Kendale Lakes was built as a planned community during the 1970s and early 1980s, and most original owners never replaced systems that technically “worked.” After 40–50 years of continuous operation in South Florida humidity, that fiberglass duct board has absorbed condensation cycle after condensation cycle, and the liner has become a contamination source. We inspect and give you straight guidance on whether cleaning, repair, or full replacement is the right call. Call (833) 628-3661 to schedule a look — estimates are free.
Yes, if the damage is isolated to a run or two and the remaining ductwork is structurally sound. We typically replace failed flex duct sections with new insulated runs and seal all connections with mastic, integrating with your existing system. Most Kendale Lakes homes need 2–4 runs addressed rather than full replacement. We’ll tell you honestly if your system has reached the point where partial repair is throwing good money after bad. Call (833) 628-3661 and we’ll assess what you’re actually dealing with.
Flat-roof homes in Kendale Lakes have limited attic clearance, so we work from access points and use flexible application tools to reach seams and joints. We apply mastic compound by brush or caulking tube — it conforms to irregular surfaces and remains flexible through thermal cycling. In tight spaces, we may remove short sections to access upstream leaks, then reinstall with sealed connections. The flat roof itself isn’t the obstacle; decades of accumulated corrosion and failed previous repairs are. We price by the scope of sealing needed, not by roof type.
We use brush-applied mastic compound for nearly all sealing work in Kendale Lakes. Mastic outperforms tape in humid environments — it doesn’t dry out, peel, or fail at temperature extremes — and we find it more reliable than aerosol sealants for the corroded seams and irregular joints common in 1970s systems. Aerosol sealing has applications in newer, intact ductwork, but for the degraded systems we encounter in Kendale Lakes, manual mastic application lets us address specific failure points with visible, verifiable coverage. We don’t sell you a technology; we use what works for your actual duct condition.
Yes. Sealed ducts deliver all the cooled air your system produces to the rooms that need it, rather than losing 20–30% to attic leaks. In Kendale Lakes, where A/C runs 10–11 months annually and attic temperatures exceed 130°F, every cubic foot of lost conditioned air is replaced by air your compressor must re-cool. Sealing typically reduces runtime and can extend equipment life by reducing cycle frequency. The savings are more pronounced here than in climates with shorter cooling seasons. Call (833) 628-3661 for a free estimate — we’ll measure your leakage and show you the specific numbers for your home.
