Fast, Reliable Duct Repair & Sealing Across Lauderhill
Duct repair and sealing in Lauderhill typically costs $280–$650 for most homes, with full duct board replacement running $1,800–$3,500 in the city’s aging 1960s–1970s housing stock. We’re usually on-site in Lauderhill within a day of your call. You can reach us at (833) 628-3661.
We’ve been working Lauderhill’s neighborhoods long enough to know what you’re up against. The concrete block ranches along State Road 7, the garden apartments near Lauderdale Lakes, the single-story homes off Sunrise Boulevard — we’ve pulled apart duct systems in all of them. Lauderhill’s housing was built fast during the 1960s and 1970s boom, and most of those original fiberglass duct board and early flex duct runs are still in place, cooked by attic heat and saturated with decades of condensation. When your AC smells musty every time it kicks on, or your bedroom never gets cool despite the system running nonstop, the problem usually isn’t the unit — it’s the ductwork falling apart above your ceiling.
Our Duct Repair & Sealing team handles everything from spot-sealing leaky joints to full duct system replacement. Owner Michael Brown leads every job personally, and we’ve got 11 years of experience specifically in air duct work — not general HVAC, not handyman services, just ducts, done right.
Why Apex Air Duct Cleaning Service Miami Is Lauderhill’s Preferred Duct Repair & Sealing Company
Local reputation built on showing up. Lauderhill homeowners and property managers call us back because Michael Brown is the one who arrives — not a subcontractor learning the trade on your clock. We’ve got 867 verified reviews averaging 4.9 stars, and plenty of those come from repeat customers in Broward County who got tired of franchise crews that send a different technician every visit.
We know the specific failures Lauderhill ducts suffer. The combination of unconditioned attics hitting 140°F, humidity that never lets up, and original duct materials never designed for 50+ years of service — that’s not a generic repair scenario. We’ve replaced delaminated duct board on NW 56th Avenue, sealed flex duct kinks in subdivisions off Inverrary Boulevard, and fixed pressure imbalances caused by window AC units punched through original duct networks near W Oakland Park Boulevard.
Professional-grade equipment, owner-operated service. We run Rotobrush and Nikro negative-pressure systems — the same equipment commercial restoration contractors use — and we carry mastic sealant, metal duct stock, and proper insulation on every truck. From cleaning to repair to sanitizing, it’s handled in one visit by one contractor you can actually reach afterward.
Our Duct Repair & Sealing Services in Lauderhill
Duct Sealing
Sealing in Lauderhill isn’t just about slapping tape on a joint. In these older homes, we test first with a duct blaster to measure actual leakage — many 1970s systems we test in Lauderhill leak 30–40% of their conditioned air into the attic. We seal accessible joints with mastic sealant (the brush-applied paste that hardens into a permanent, flexible bond) and mechanical fasteners. For systems with widespread deterioration, we’ll tell you straight if sealing is throwing good money at bad material.
Flex Duct Repair
Lauderhill’s flex duct runs through unconditioned attics sag between trusses, kink at turns, and collect debris where they dip. We’ve found flex duct in homes near State Road 7 so compressed it’s passing less than half its rated airflow. We replace damaged sections with properly supported new flex, seal connections with mastic, and add hangars where the original installation failed. In some cases, we’ll recommend upgrading critical trunk lines to metal where flex has failed repeatedly.
Metal Duct Repair
Where Lauderhill homes have metal trunk lines — sometimes original, sometimes a previous owner’s partial upgrade — we repair rust-through, reseal separated seams, and replace damaged takeoffs. Metal duct in Lauderhill’s humid attics corrodes at the seams where mastic or original tape has failed. We reseal with fresh mastic and reinforce with metal screws, not duct tape that’ll peel in the heat.
Duct Insulation
This is critical in Lauderhill. Unconditioned attic spaces here regularly exceed 140°F, and any duct without intact insulation is basically trying to cool your house with a radiator. We replace delaminated fiberglass insulation with formaldehyde-free duct wrap rated for high-humidity environments, sealed with vapor-barrier mastic. For metal trunks, we sometimes recommend double-wall insulated duct where the application warrants it. Proper insulation in Lauderhill isn’t an upgrade — it’s what makes the rest of the repair actually work.
Mastic Sealant Application
We use fiber-reinforced mastic sealant on every joint, seam, and penetration — not foil tape, not “duct tape,” which fails in Lauderhill’s heat and humidity within months. Mastic remains flexible, seals irregular surfaces, and is the standard specified by ASHRAE for permanent duct sealing. We apply it thick, let it cure properly, and don’t bury it behind insulation until it’s set.
Air Leak Repair
Window AC units installed after the original construction are a Lauderhill specialty problem. These units punch holes through walls that intersect with original duct networks, letting 140°F attic air infiltrate the system and throwing pressure balances off across the whole house. We seal these penetrations properly, restore duct continuity, and often find that “mystery” hot rooms suddenly cool evenly once the pressure balance is restored.

Trusted Brands We Service in Lauderhill
We work with Honeywell, Aprilaire, and Guardsman air quality components regularly — and we stock common replacement parts so Lauderhill customers aren’t waiting on shipping. Our Rotobrush and Nikro cleaning and repair equipment is professional-grade, not the consumer-grade shop vacs some competitors bring. When we recommend a specific filter, humidistat, or UV sanitizer for your Lauderhill home, it’s because we’ve installed that exact component in similar conditions and know how it performs in South Florida’s humidity.
Common Duct Repair & Sealing Problems We See in Lauderhill Homes
- Original fiberglass duct board delaminates from moisture. In Lauderhill’s 1960s–1970s CBS homes, decades of condensation soak the fiberglass until it crumbles, shedding glass fibers into your airflow and making any seal impossible. We see this as the norm, not the exception, in homes that haven’t had duct replacement.
- Window AC units punch holes in ductwork. Common in rental properties and older homes near Sunrise Boulevard, these unsealed penetrations let superheated attic air infiltrate the central duct system, creating pressure imbalances and forcing the AC to run longer for less cooling.
- Flex duct sags and kinks in unconditioned attics. Lauderhill’s attic temperatures accelerate flex duct deterioration, and original installations often lacked proper support. Sagging sections trap debris, block airflow, and become mold reservoirs even after surface sealing.
- Original insulation has delaminated and sheds particulates. We regularly find insulation in Lauderhill homes that has separated from the duct surface, collapsing into the airstream or falling away entirely — meaning your ducts are cooling the attic instead of your living space.

What moves you within these ranges? Accessibility (tight attics take longer), extent of damage (spot repair versus full replacement), and whether we’re working around existing insulation or removing it. Lauderhill’s older homes often need more extensive work than newer construction because the original materials have simply reached end of life. We give upfront pricing before any work begins — call (833) 628-3661 for a free estimate.

FAQs — Duct Repair & Sealing in Lauderhill
If the duct board is intact and dry, we can seal joints and penetrations with mastic. In most Lauderhill homes we inspect, however, the fiberglass has delaminated from decades of condensation saturation — once it crumbles or sheds fibers, sealing is ineffective and we recommend full replacement with sealed metal trunk and properly supported flex runs. Call (833) 628-3661 and we’ll assess what you’ve actually got up there.
Sealing alone won’t fix musty odors if the flex duct interior is contaminated with mold or if sagging sections trap debris. In Lauderhill’s humidity, we often find that sealed but dirty flex still smells. We typically recommend cleaning or replacement combined with sealing, plus proper support to prevent future sagging. For an exact diagnosis of your odor source, call (833) 628-3661 for a free inspection.
Fiber-free formaldehyde-free duct wrap with a vapor-barrier jacket, rated for high-humidity applications and installed with mastic-sealed seams. In Lauderhill’s 140°F attics, standard fiberglass batt insulation delaminates and collapses within years. We size insulation thickness to the R-value appropriate for your duct size and attic conditions — typically R-6 to R-8 for supply trunks in this climate.
New construction standards target less than 5% leakage. In the 1970s Lauderhill homes we test, 30–40% leakage is common, and we’ve measured over 50% in systems with original duct board and multiple DIY modifications. Anything above 15% is costing you significantly in cooling efficiency and indoor air quality. A duct blaster test gives you the exact number for your home.
Yes — this is a frequent find in Lauderhill’s older homes and long-term rentals. We seal the wall penetrations properly with fire-rated foam and mastic where they intersect ductwork, restore duct continuity, and rebalance airflow. Often this single repair resolves “mystery” hot rooms that never cooled properly. Call (833) 628-3661 for an estimate — we’ll check your whole system while we’re there.
