AfterFast, Reliable Duct Sealing Across North Lauderdale
Duct sealing in North Lauderdale typically runs $450 – $1,200 for a whole-home seal on a standard ranch or townhome, with most jobs completed in a single visit. If your vents whistle, your bedroom never cools, or your electric bill climbs every summer, the problem is usually air leaking out of corroded or disconnected ductwork before it ever reaches your rooms.
We’ve worked the 1960s and 1970s subdivisions from Rock Island to Hampton Pines, and we know what hides above those low-slung ceilings. Our crews dispatch from our Miami office and carry mastic, mesh, and camera gear sized for North Lauderdale’s compact attics and slab-on-grade foundations. When you call (361) 326-5060, a live person answers, 24 hours a day. We’ll give you a written price before any work starts, and every seal is covered by our 365-Day Done Right Promise.
Why Hollis Air Duct Cleaning Is North Lauderdale’s Preferred Duct Sealing Company
Hollis Air Duct Cleaning has been part of the Garrison Partners family since 2004. In North Lauderdale, that longevity matters because we’ve watched the same housing stock age through two decades of subtropical summers. We know which developments along McNab Road and SW 71st Avenue still run original galvanized trunks, and we know what happens when afternoon thunderstorms drive water through aging roof vents into those attic runs.
Our technicians are background-checked, uniformed, and held to The Garrison Code: arrive inside the quoted window, price in writing, complete the job by the book, leave the site clean. We don’t send salespeople in technician uniforms. The person who inspects your ducts is trained to operate our Nikro negative-air equipment and apply mastic with the same discipline we’d use on a commercial job.
Phones are answered by a live person, 24/7. No voicemail loops, no callback queues, no waiting until Monday to schedule. When North Lauderdale homeowners have a blower motor short-cycling or a musty smell that won’t clear, they don’t want an appointment two weeks out. They want a crew that shows up squared away and finishes the same day.
Duct Sealing Services in North Lauderdale
Duct Sealing Services in North Lauderdale address a specific problem: conditioned air escaping through gaps, cracks, and corroded seams in your ductwork before it reaches your rooms. In this city’s 1960s – 80s housing stock, we regularly find original galvanized steel ducts that have rusted from the inside out, where the metal looks solid from the outside but is pitted and porous where moist air passes through. A typical whole-home seal runs $450 – $1,200 depending on accessibility and the extent of damage found during inspection.
Camera-Assisted Leak Detection
We feed a borescope through the duct runs before we seal anything. In North Lauderdale ranches with slab foundations, this is how we find crushed or disconnected runs hidden under the concrete or buried in tight attic chases. Sealing the accessible seams while missing a major disconnection is wasted money and wasted mastic.
Mastic and Mesh Application
For accessible joints and seams that are structurally sound, we apply professional-grade duct sealing matic reinforced with fiberglass mesh. This creates a flexible, durable seal that moves with the duct as temperatures shift. We don’t use duct tape, which dries and fails in Florida’s heat within a single season.

Duct Insulation in North Lauderdale
Duct Insulation in North Lauderdale protects against a problem most homeowners don’t see until it’s severe: attic moisture soaking through degraded insulation, causing it to sag and pull ducts away from collars. In this city’s subtropical climate with average relative humidity above 70%, poorly insulated attic runs lose cooled air rapidly and become condensation points that breed mold. Replacing wet or compressed insulation on accessible attic ducts typically costs $300 – $800 for a standard ranch.
Attic Run Recovery After Storm Damage
North Lauderdale’s afternoon thunderstorms regularly drive water through aging roof vents into attic spaces. We pull the saturated insulation, inspect the duct beneath for corrosion, and install new foil-faced insulation with proper vapor barriers. Without this step, even a perfect mastic seal will fail when the duct shifts in sagging, waterlogged wrap.
Insulation Assessment During Sealing
Every duct sealing job we perform includes an insulation check on accessible attic runs. If the R-value has collapsed or the vapor barrier is torn, we flag it in writing before we start. You decide what to address now versus later, but you’ll know the condition of the full system, not just the seams we can reach.
Trusted Brands We Service in North Lauderdale
Our trucks carry professional-grade equipment from Nikro and Abatement Technologies, plus filtration and control products from Honeywell and Aprilaire. For North Lauderdale homeowners, this means we stock the parts and materials to complete most jobs without waiting on a warehouse delivery. Our Nikro negative-air machines maintain proper containment during duct disturbance, and our Honeywell media filters integrate cleanly with older systems that can’t accommodate modern electronic air cleaners. When a 1970s ranch needs a component we don’t carry, our Miami office coordinates same-day or next-morning pickup from regional distributors who know our account.
Common Duct Sealing Problems We See in North Lauderdale Homes
- Galvanized steel corrosion from the inside out. Original ducts in 1960s – 70s North Lauderdale ranches look intact from the outside but are pitted and porous where decades of 70%-plus humidity have eaten the zinc coating. Mastic alone won’t hold on compromised metal; we identify where replacement outperforms repair.
- Storm-soaked attic insulation pulling collars loose. After heavy afternoon thunderstorms, waterlogged insulation sags and drags ductwork away from sealed joints. We see this pattern repeatedly in developments near Hampton Pines, where roof vents from the original build have never been replaced.
- Crushed or disconnected runs under slab foundations. North Lauderdale’s ranch-style slabs hide ductwork that settles, cracks, or gets damaged during prior plumbing or pest work. Without camera inspection, these leaks stay invisible while homeowners pay to cool their concrete.
- Failed DIY repairs masking deeper damage. We find duct tape, spray foam, and even caulk slapped over gaps that needed structural attention. These shortcuts trap moisture against metal and accelerate the corrosion they were meant to stop.
Pricing for Duct Sealing in North Lauderdale, FL
A typical duct sealing job in North Lauderdale runs $450 – $1,200 for a whole-home seal on a standard one-story ranch or townhome. Duct insulation replacement on accessible attic runs adds $300 – $800. What moves the number: how much of the system is accessible without cutting drywall, whether we find galvanized duct that needs section replacement rather than sealing, and whether camera inspection reveals crushed or disconnected runs requiring repair before any seal will hold.
We give every North Lauderdale homeowner a written price before any work starts. That price does not move at the door. No per-vent add-ons, no “while we’re here” upsells. If we open a chase and find damage we couldn’t see during inspection, we stop, show you the camera feed, and write a revised price for your approval. Nothing happens without your sign-off.

FAQs About Duct Sealing in North Lauderdale
Because original galvanized steel ducts in this era’s ranches corrode from the inside out in North Lauderdale’s 70%-plus average humidity, and no amount of cleaning seals a hole. Cleaning removes debris; sealing restores the pressure boundary that forces air through your registers instead of into your attic or wall cavities. If your ducts are leaking, cleaning them again just evacuates the conditioned air faster. Call (361) 326-5060 and we’ll camera-inspect to show you exactly where the air is going.
We use a borescope camera fed through the duct runs to inspect areas we can’t reach physically. In slab-on-grade homes common throughout North Lauderdale, ducts run through the concrete or through tight soffits with no access panels. Camera inspection lets us see collapses, disconnections, and standing water before we quote any sealing work. Without it, we’d be sealing ducts that aren’t even connected to your air handler. Call (361) 326-5060 to schedule a camera inspection.
Wet insulation usually means you need insulation replacement first, then sealing assessment once the ducts are exposed. In North Lauderdale, afternoon thunderstorms drive water through aging roof vents so regularly that local techs know to inspect attic duct insulation immediately after any summer storm. Saturated insulation sags, pulls collars loose, and reopens sealed joints. We remove the wet material, inspect the metal beneath for corrosion, replace the insulation, then seal any gaps that have developed. Call (361) 326-5060 for an inspection after the next heavy rain.
Yes, if the smell is coming from mold growing in moist, leaky ductwork – which is common in North Lauderdale’s older homes. When ducts leak into hot attic spaces, they draw in humid air that condenses on cool metal and breeds microbial growth. Sealing the leaks stops this infiltration, and pairing sealing with proper insulation prevents the condensation that feeds new growth. On that 1968 ranch off SW 76th Avenue, the musty odor in the back bedroom cleared within a week of our sealing and replacement work. Call (361) 326-5060 if you’re dealing with persistent odors.
Yes. Our technicians are trained to NADCA assessment and sealing protocols, adapted for the specific conditions we find in North Lauderdale’s 1960s – 80s housing stock. That means camera inspection before sealing, mastic and mesh on structurally sound metal, and honest recommendations for section replacement where galvanized ducts have corroded through. The standard matters because it prevents the shortcut of sealing metal that won’t hold a seal. Call (361) 326-5060 to discuss how we apply it to your home.
