We’ve been driving out to Sunrise from our Miami base for years — long enough to know the difference between a quick mastic touch-up on a 1990s system and a full flex duct replacement in one of those original Inverrary builds. Sunrise’s 1970s–1980s planned communities put this city on the map, but that same housing stock is now pushing 50 years old, and the ductwork shows it. We’re the Duct Repair & Sealing crew that actually understands what those aging fiberglass boards and original flex runs look like when they start failing — because we’ve opened hundreds of them across Sunrise, from Springtree to the neighborhoods off Oakland Park Boulevard.
Why Apex Air Duct Cleaning Service Miami Is Sunrise’s Preferred Duct Repair & Sealing Company
Sunrise homeowners don’t need another contractor who treats their city like “west Broward” — they need someone who knows that a home near the Sawgrass Mills area faces different humidity loads than one closer to the Everglades edge, and that both probably have ductwork older than the homeowner.
Our reputation here is built on showing up and doing the work ourselves. Owner Michael Brown serves as lead technician on every job — not a rotating subcontractor, not a new hire with a week’s training. That’s 11 years in this single trade, with professional-grade Rotobrush and Nikro equipment, handling everything from cleaning to repair to sealing in one visit. Our 867 verified reviews at 4.9 stars include plenty from Sunrise customers who found us after another company suggested a full replacement for what turned out to be a repairable issue.
We know the local permitting landscape for duct modifications in Broward County. We know which Sunrise neighborhoods have attic access constraints from those low-slope 1970s roofs. And we know that when we get a call from someone in the 33304 ZIP code complaining about “dust that never goes away,” there’s a real chance we’re going to find delaminated fiberglass duct board — not ordinary household dust at all.
Our Duct Repair & Sealing Services in Sunrise
Duct Sealing
Original mastic seals in Sunrise homes have had 40–50 years to dry out and crack. Every summer, those gaps pull hot, humid attic air into your cooled supply lines — and on the return side, they suck in fiberglass particles, rodent droppings, and whatever else lives in that tight 1970s attic space. We seal with fresh mastic compound and reinforced mesh at every joint, boot, and penetration. In Sunrise’s climate, proper sealing typically pays for itself in 18–24 months through reduced AC runtime.
Flex Duct Repair
The flex duct installed during Sunrise’s building boom was never designed for five decades of continuous operation. The inner liner collapses. The insulation gets waterlogged from condensation that never dries. Mold colonies establish in the sagging low points. We replace collapsed sections with new, properly supported flex duct — sized correctly for the original airflow design, not whatever the hardware store had in stock. We see this failure constantly in Springtree and the older phases of Inverrary, where the original flex runs through unconditioned attic spaces that hit 140°F in August.
Metal Duct Repair
Some Sunrise homes — particularly later 1980s builds and any with commercial-style package units — have galvanized metal trunk lines. These don’t delaminate like fiberglass, but they corrode at seams, separate at drive connections, and transmit noise like a drum. We repair metal duct with proper slip joints, seal with mastic (never duct tape — that fails in months here), and add insulation where the original has degraded. Metal repair in Sunrise often makes sense when the trunk is structurally sound but the connections have failed from decades of thermal expansion.
Duct Insulation
Uninsulated or degraded duct insulation in a Sunrise attic is like running your AC with the windows open. We replace waterlogged, compressed, or mold-contaminated insulation with fresh fiberglass wrap or closed-cell foam where appropriate, sealed with vapor barriers rated for South Florida’s humidity. This matters especially for Sunrise homes near the western edge, where Everglades moisture and afternoon thunderstorms keep ambient humidity elevated even overnight.
Mastic Sealant Application
Mastic is the only sealant we trust for Sunrise’s conditions. Duct tape dries and fails; aerosol sealants don’t penetrate properly on degraded fiberglass board. We brush-apply fiber-reinforced mastic at every joint, every takeoff, every damper connection. It’s messy, slow, and permanent — the way this work should be done. For a typical Sunrise split-level, full mastic sealing takes 4–6 hours and addresses the air leaks that most homeowners don’t know they have.

Trusted Brands We Service in Sunrise
We work with Honeywell and Aprilaire air quality components regularly — controls, filtration media, and fresh air intake systems that integrate with repaired ductwork. Our Rotobrush and Nikro negative-pressure equipment is what we use for pre- and post-repair cleaning, ensuring we’re not sealing contaminants into your system. For Sunrise customers with specific component needs, we source parts through our established supply relationships rather than making you wait for special orders. That means faster turnaround on repairs, especially when we’re dealing with older systems where matching fittings takes knowledge most crews don’t have.
Common Duct Repair & Sealing Problems We See in Sunrise Homes
- Fiberglass duct board delamination. The original fiberglass duct board in 1970s Sunrise homes — common throughout Inverrary — separates at the interior liner after decades of moisture cycling. Homeowners describe “dust that keeps coming back.” It’s not dust. It’s fiberglass particles. This requires replacement, not cleaning.
- Flex duct liner collapse. The wire-reinforced inner liner of original flex duct sags and collapses in the humid attic environment, creating blockages that strain the AC blower and create back-pressure zones where mold proliferates.
- Failed original mastic seals. The mastic applied in 1978 has long since crystallized. Cracked seals at trunk connections and takeoff boots leak conditioned air into the attic and pull in contaminants — wasting 20–30% of cooling energy in some homes we’ve tested.
- Condensation-driven mold in low points. Sunrise’s year-round AC operation means ducts never warm enough to fully dry. Any sag in flex duct, any gap in insulation, becomes a drip point where mold establishes and spreads through the airstream.

These ranges reflect what we actually charge Sunrise homeowners — not national averages, not bait-and-switch estimates. Final cost depends on attic accessibility, extent of damage, and whether we’re working with original 1970s fittings that require custom adaptation. Homes in the older Inverrary sections sometimes need more extensive replacement than initially visible, which is why we always inspect with a borescope before quoting. Every estimate is free, delivered in writing, and valid for 30 days. Call (833) 628-3661 to schedule.

FAQs — Duct Repair & Sealing in Sunrise
Look for persistent fine “dust” that returns within days of cleaning, increased allergy symptoms when the AC runs, or visible deterioration at any accessible register boot. In Sunrise’s 1970s–1980s homes, failing fiberglass duct board is common enough that we recommend inspection if your home dates to that era and you’ve never had the ductwork evaluated. Call (833) 628-3661 — estimates are free, and we’ll show you exactly what the borescope reveals.
We can repair isolated sections if the remaining duct is structurally sound, but most 1970s flex duct in Sunrise has degraded beyond reliable repair. The liner becomes brittle, the insulation compresses, and moisture damage is typically systemic rather than localized. We’ll give you an honest assessment of what’s repairable versus what needs replacement — no pressure to replace what we can fix. Call (833) 628-3661 for an inspection.
Sunrise’s housing stock is 20–30 years older on average, with original duct materials that have endured far more moisture cycles. Weston homes built in the 1990s–2000s use more durable flex duct and better initial sealing. Additionally, Sunrise’s western position adjacent to the Everglades transition zone means higher ambient biological loads and humidity that penetrate attic spaces more aggressively. Call (833) 628-3661 if you’re seeing musty odors or visible mold around registers.
Yes — sealing is non-negotiable in this climate. Unsealed joints in Sunrise’s humidity allow continuous moisture infiltration that undoes repair work within seasons. We apply fresh mastic at every connection as standard procedure, not as an upsell. The sealant we use is rated for sustained 90%+ relative humidity. Call (833) 628-3661 to discuss what’s involved for your specific system.
It depends on the extent of fiberglass duct board failure. Isolated delamination in one trunk section is repairable; systemic liner failure throughout multiple branches usually warrants full replacement with modern flex duct. We’ve done both in Inverrary homes, and we’ll tell you straight which path makes financial sense for your situation. Replacement typically runs $2,800–$4,500 for an average Sunrise home — repair is often one-third of that when feasible. Call (833) 628-3661 for an honest evaluation.
