We’ve been working the 33064 ZIP for years, and here’s what we’ve learned: Pompano Beach Highlands isn’t like the master-planned communities ten miles west. This is a mid-century residential pocket where the bulk of housing went up during the 1960s–1970s Florida development boom, and a lot of those original duct systems are still in place. They’ve endured decades of near-constant AC operation in coastal Broward County humidity, producing mold and biological fouling loads inside ductwork that are far heavier than in newer-built South Florida communities. That’s not a scare tactic — it’s what we find when we open attic hatches on Sample Road, on NE 10th Street, and throughout the Palm Aire neighborhood.
Our Duct Repair & Sealing team knows these houses. We know which attic runs are prone to collapse, where the salt air attacks metal first, and how to fix it so the repair lasts.
Why Apex Air Duct Cleaning Service Miami Is Pompano Beach Highlands’s Preferred Duct Repair & Sealing Company
Owner-operated and owner-present. Michael Brown is the lead technician on every job. You’re not getting a rotating subcontractor who might not show up tomorrow — you’re getting the person whose name is on the company and whose reputation is built on 867 verified reviews averaging 4.9 stars. In Pompano Beach Highlands, that accountability matters, because ductwork in these older homes requires judgment calls that come from experience, not a script.
11 years, one trade. We’ve spent over a decade focused exclusively on air duct and HVAC cleaning. We’re not generalists who added duct cleaning as an upsell. That depth shows when we’re crawling through 140°F attics in Pompano Beach Highlands, tracing collapsed flex runs back to their source, and determining whether a section can be salvaged or needs full replacement.
Professional-grade equipment. We run Rotobrush rotary brush systems and Nikro negative-pressure vacuums — the same tools commercial restoration contractors use, not consumer-grade shop vacs. For sealing, we apply mastic sealant and work with R8 insulated flex duct rated for Florida attic conditions.
From cleaning to repair to sanitizing — handled in one visit. Many Pompano Beach Highlands customers call us for a duct cleaning and discover their system needs more. We don’t hand you off to another contractor. We repair, seal, and sanitize in-house, including air quality products from Honeywell and Aprilaire.
Our Duct Repair & Sealing Services in Pompano Beach Highlands
Flex Duct Repair
This is our most common call in Pompano Beach Highlands, and it’s no accident. The 33064 ZIP is dominated by 1960s–1970s concrete block structure homes with ductwork routed through unconditioned attic spaces. Those attics routinely exceed 140°F in summer. Decades of thermal stress cause the flex duct liner to become brittle, delaminate, and collapse at joints — a failure mode we rarely see in neighborhoods built after 1990. On a recent job in the Palm Aire neighborhood off Atlantic Boulevard, we found a 1970s CBS home where the flex duct had completely separated at the main trunk joint due to heat degradation. We replaced the damaged run with R8 insulated flex duct, sealed all connections with mastic, and installed a Honeywell ultraviolet air purifier to prevent future mold buildup. Typical flex duct repair in Pompano Beach Highlands runs $320–$580 depending on run length and accessibility.
Mastic Sealant Application
Duct tape fails in Florida attics. The adhesive degrades; the tape peels; the leaks return. We seal with mastic — a thick, fiber-reinforced compound that remains flexible and bonds permanently to metal and flex duct surfaces. In Pompano Beach Highlands, where salt-laden air corrodes metal joints and register boots, mastic sealing is often the difference between a repair that lasts five years and one that fails in eighteen months. We apply it by hand at every connection, every boot, every penetration. Mastic sealing work in Pompano Beach Highlands typically costs $280–$450 for a whole-system treatment.
Duct Sealing & Air Leak Repair
Leaky ducts don’t just waste energy — they pull humid, unfiltered attic air into your living space. In Pompano Beach Highlands, where humidity stays above 80% most of the year, that means mold spores, fiberglass particles, and whatever else is in your attic ends up in your bedrooms. We pressure-test the system, locate leaks with smoke pencils and thermal imaging, then seal methodically. For homes near the Atlantic, we also inspect for salt corrosion at metal joints, which creates pinhole leaks that standard duct cleaning misses entirely. Duct sealing and leak repair in Pompano Beach Highlands generally runs $350–$620.

Metal Duct Repair
Some Pompano Beach Highlands homes have galvanized metal trunk lines or transitions that have developed corrosion holes, separated seams, or damaged dampers. Sitting roughly 3 miles inland from the Atlantic, this area gets salt-laden air that attacks metal duct joints and register boots years faster than in western Broward County. We patch, replace sections, or fabricate transitions as needed, then seal with mastic. Metal duct repair in Pompano Beach Highlands typically ranges from $340–$650 depending on extent and material gauge.
Duct Insulation
Uninsulated or poorly insulated duct runs in Pompano Beach Highlands attics sweat condensation, which feeds mold growth and reduces cooling efficiency. We install R8 insulation on flex duct replacements and can retrofit insulation on existing metal runs where accessible. This is especially critical in the 33064 ZIP, where the AC season runs 10–12 months annually and every thermal loss costs you money. Duct insulation work runs $380–$720 in this market.

Trusted Brands We Service in Pompano Beach Highlands
We work with Honeywell, Aprilaire, and Abatement Technologies air quality products, and we stock common flex duct, fittings, and mastic supplies for Pompano Beach Highlands customers so we’re not waiting on deliveries while your attic stays open. Our Nikro and Rotobrush equipment handles the cleaning side; our repair work uses industry-standard materials rated for Florida’s humidity and thermal extremes. When we install a Honeywell UV air purifier or an Aprilaire filtration upgrade, it’s because we’ve tested these products in local conditions and know they hold up.
Common Duct Repair & Sealing Problems We See in Pompano Beach Highlands Homes
- Flex duct liner collapse from decades of attic thermal stress. The 1960s–1970s housing stock in Pompano Beach Highlands means original flex duct has spent 50+ years in 140°F attics. The inner liner becomes brittle, cracks, and collapses, restricting airflow or blocking it entirely. We find this on roughly half the older homes we inspect in the 33064 ZIP.
- Corrosion of metal duct joints and register boots from salt-laden coastal air. Pompano Beach Highlands sits close enough to the Atlantic that salt air accelerates rust and galvanic corrosion at metal connections. Pinhole leaks develop; boots separate from drywall; the system pulls attic air through gaps that grow every season.
- Mold colonization inside uninsulated or poorly sealed duct runs. Year-round humidity above 80% creates constant condensation on cool duct surfaces. Add decades of accumulated dust and organic material, and you’ve got conditions where mold colonization is almost inevitable without periodic cleaning and proper sealing.
- Separated joints and sagging runs from improper original installation. Many Pompano Beach Highlands homes were built during the Florida boom years, when speed sometimes trumped precision. We’ve found flex duct supported by flimsy wire hangers that have rusted through, causing runs to sag, kink, or pull apart at connections.

FAQs — Duct Repair & Sealing in Pompano Beach Highlands
Yes — a significant share of homes in the 33064 ZIP still run on original or early-generation flex duct installed during the 1960s–1970s construction boom. That ductwork has endured decades of 140°F attic heat and near-constant AC operation, so it’s often brittle, partially collapsed, or leaking at multiple joints. If your home was built in this era and you’ve never had the ducts replaced, an inspection is worth scheduling. Call (833) 628-3661 — estimates are free.
Salt-laden coastal air accelerates corrosion of metal duct joints, register boots, and fasteners, creating pinhole leaks and separated connections that standard duct cleaning won’t fix. We inspect for this specifically on every Pompano Beach Highlands job, and we use mastic sealing and corrosion-resistant materials where metal has degraded. The salt effect is real here — roughly 3 miles inland is close enough to matter. Call (833) 628-3661 for an inspection.
Because cleaning a damaged duct system is temporary at best. In Pompano Beach Highlands, we frequently find that “dirty ducts” are actually collapsed, leaking, or mold-colonized ducts — and until the structural problems are repaired and sealed, debris and contamination reaccumulate quickly. We assess integrity before cleaning, and we’ll tell you honestly if repair needs to come first. Call (833) 628-3661 and we’ll evaluate whether cleaning alone will solve your problem.
Mastic sealant applied by hand at every joint, boot, and penetration — not duct tape, which fails in Florida heat and humidity. For 1970s Pompano Beach Highlands homes with metal transitions and flex duct runs, we typically combine mastic sealing with replacement of degraded flex sections using R8 insulated duct rated for attic conditions. The concrete block construction itself is durable; it’s the original ductwork that needs attention. Call (833) 628-3661 for a specific plan for your home.
Yes — separated flex duct is one of our most common repairs in Pompano Beach Highlands, usually caused by thermal degradation of the inner liner after decades in hot attics. We replace the damaged section with new R8 insulated flex duct, secure it with proper supports, and seal all connections with mastic. In many cases, we can complete this repair and restore full airflow in a single visit. Call (833) 628-3661 for an exact quote — estimates are free.
