Fast, Reliable Duct Sealing Across Fort Lauderdale
Duct sealing in Fort Lauderdale stops conditioned air from leaking out of your ductwork before it ever reaches your rooms. Most Fort Lauderdale homes lose 20 – 30% of the air they pay to cool through gaps in original duct runs, and in our coastal climate that waste never takes a day off. Our crews know the difference between a poorly sealed seam in a 1962 ranch near Croissant Park and a rust-pitted riser in a beachfront high-rise on A1A. If your AC runs long and your rooms still don’t cool, call (754) 354-3644 for a straight answer instead of another band-aid repair.
Why Hollis Air Duct Fort Lauderdale Is Fort Lauderdale’s Preferred Duct Sealing Company
We are not the newest name in Fort Lauderdale’s duct trade, and we don’t try to be. Founded in 2004 as part of the Garrison Partners family, Hollis Air Duct Cleaning runs on The Garrison Standard: written prices before any work starts, background-checked uniformed technicians, and a 365-Day Done Right Promise in writing on every single job. What that means for a homeowner in Fort Lauderdale is simple. The price we quote for sealing your ducts is the price you pay. If the seal fails within a year, we return and make it right at no charge, including a free second visit. No fine print, no re-negotiation at the door.
Local knowledge is not a slogan here. Fort Lauderdale’s housing stock is not one thing. It is 1950s – 1970s single-family homes with original galvanized duct runs under slab, and it is high-rise condo risers carrying salt-laden air from the Atlantic. A sealed seam that holds fine in a dry inland house can fail in 2 – 3 years along the Intracoastal if the metal underneath was not prepped for chloride exposure. Our crews see the difference before they touch a brush to the metal. That is the kind of judgment that keeps Fort Lauderdale customers calling us back instead of calling around.
Owner Roy Castellanos expects every Hollis technician to follow The Garrison Code on the job: arrive inside the written window, price in writing before work begins, do the work by the book, and leave the site cleaner than we found it. That is what a disciplined duct sealing crew looks like in Fort Lauderdale. Call (754) 354-3644 and a live person answers, 24/7. No voicemail loops, no waiting until Monday.
Styles & brands we work with
Duct Insulation in Fort Lauderdale
Duct insulation in Fort Lauderdale is not a comfort upgrade. It is a moisture control measure. When cold supply ducts run through a hot, humid attic, condensation forms on the outside of the metal. That condensate soaks into surrounding insulation, drips onto drywall, and creates the damp environment where mold takes hold. Fort Lauderdale’s summer dew points make this problem worse here than almost anywhere in the state. A typical duct insulation job in Fort Lauderdale runs $800 – $1,600 depending on the linear footage of accessible ductwork, and it pairs naturally with duct sealing because a sealed, insulated duct is the only duct that stays dry.
Attic and Crawlspace Wrap
We wrap supply and return ducts with fiberglass or closed-cell insulation, then seal every joint and seam before the wrap goes on. The order matters. Insulating over a leaking seam traps moisture between the insulation and the metal, which rots the duct from the outside in.
Condensation Damage Repair
Rusted duct bottoms and soggy insulation are the telltale signs of under-insulated runs in older Fort Lauderdale homes. We replace the damaged section, seal it, and wrap it to the proper R-value for south Florida’s humidity, not a northern standard.
HVAC Duct Sealing in Fort Lauderdale
HVAC duct sealing in Fort Lauderdale means closing the gaps in your supply and return ductwork so the air your blower moves actually reaches your living spaces. In a typical 1960s Fort Lauderdale home, we find seams pulled apart, duct tape that lost its adhesive decades ago, and runs crushed by shifting sandy soil. Duct sealing costs $450 – $950 for most single-family homes in Fort Lauderdale, depending on how much of the ductwork is accessible and how many failed seams we find. Condo risers and common-ventilation shafts run higher because access and liability change the scope.
Mastic and Mesh Sealing
We seal accessible supply and return ducts with mastic and fiberglass mesh, the NADCA-standard method that bridges voids rather than just covering them. In Fort Lauderdale’s salt air, surface preparation is the step that determines whether a seal lasts two years or ten.
Camera Inspection First
Before we seal anything, we run a Rotobrush camera inspection through the accessible runs. You will see what we see: the actual disconnected seams, rust pitting, and gaps. Then we price the sealing work in writing, based on that footage, not a guess.
Trusted Brands We Service in Fort Lauderdale
We work with the filter and air-quality brands Fort Lauderdale homeowners already know, including Honeywell and Aprilaire. When we seal a system, we check the filter housing and blower cabinet for gaps that let unfiltered attic or wall-cavity air bypass the filter entirely. We stock common filters and replacement components for those brands locally, so most Fort Lauderdale jobs are completed same-day without waiting on a parts truck from out of county. A sealed duct with a poorly fit filter is still a leak. We fix both.
Common Duct Sealing Problems We See in Fort Lauderdale Homes
- Salt-corroded seams in beachfront and Intracoastal high-rises: Salt spray enters common ventilation shafts and attacks galvanized steel at the seams. Mastic applied over corroded metal will crack within 2 – 3 years as micro-corrosion works underneath it. Our crews clean and prep the surface before sealing, or replace the section if rust has already pitted through.
- Disconnected runs under slab in 1950s – 1970s homes: Shifting sandy soil across Fort Lauderdale’s limestone base settles and pulls original slab ducts apart at the joints. Sealing cannot restore airflow until the disconnected or crushed section is replaced. We find this most often in older neighborhoods like Croissant Park and Riverside Park.
- Mastic-only repairs on salt-corroded galvanized ducts: A previous contractor sealed with mastic alone, and the joint cracked as soon as the salt and humidity got to work. Brittle, pitted joints have to be addressed at the metal level first. Our written guarantee takes the risk of a repeat off you.
- Shared-riser pinhole leaks delivering marine air past the filter: In Fort Lauderdale’s beachfront condos, a rust-through pinhole in a common riser lets musty, humid marine air bypass the filter and re-contaminate the ducts you just paid to clean. Sealing the riser joints is the difference between clean air and ocean smell that keeps coming back.

FAQs About Duct Sealing in Fort Lauderdale
Because the moisture source was never stopped. In Fort Lauderdale, mold returns when humid outdoor air keeps entering the ducts through unsealed seams or when condensation forms on uninsulated metal in a hot attic. If the ducts were sealed without first addressing every air leak and wrapping cold surfaces, the mold reestablishes within months. We seal and insulate together, then verify with a camera. Call (754) 354-3644 and we will show you the footage of where air is still getting in.
Yes, when the smell is coming from rust-through pinholes in the shared riser. Salt-laden marine air corrodes galvanized ducts in A1A and Intracoastal buildings until small holes open at the seams. Musty air bypasses your filter and rides straight into the unit. Sealing the riser joints and replacing pitted sections stops that pathway. It will not fix a smell that originates inside the unit from a wet coil or drain pan, which is why we inspect before we seal.
Expect us to find things the previous homeowner never saw. Original 1960s slab ducts in Fort Lauderdale often have separated seams and crushed sections from decades of soil settlement. We run a camera first to map the failures, then seal every accessible joint with mastic and mesh and replace any section that is beyond repair. The price is written before work starts, based on that footage. Call (754) 354-3644 to schedule the inspection.
Every 3 – 5 years if you live within a mile of the ocean, and every 5 – 7 years inland. Salt chloride levels along Fort Lauderdale’s coast accelerate seam corrosion faster than almost any other local condition. Our 365-Day Done Right Promise covers our work for a full year, but in beachfront buildings we recommend a camera check of the riser seams every few years before pinholes turn into full air-quality failures.
It usually does. When supply ducts leak into a hot chase or return ducts pull humid wall-cavity air, the AC runs longer to reach the thermostat setpoint. In a Fort Lauderdale summer, that means your electric meter is spinning to cool air you never feel. Sealing the accessible runs and riser joints reduces that waste, often cutting runtime by 15 – 25% in units we have serviced. Call (754) 354-3644 for an inspection and we will tell you honestly if sealing will move the needle on your bill.
What We Actually Find Inside Fort Lauderdale Ductwork
Salt-laden air from the Atlantic accelerates rust and galvanic corrosion in galvanized steel ductwork across Fort Lauderdale, and the beachfront high-rises along A1A see premature pitting at duct seams far sooner than inland cities like Plantation or Sunrise. That is the single biggest difference between duct sealing here and duct sealing almost anywhere else. A seam that would hold for twenty years in a dry inland climate becomes brittle and cracked after a few years of salt-chloride exposure. Our crews see it every week in Fort Lauderdale’s older buildings: pinholes at the joints, rust bloom around the mechanical fasteners, and collapsed sections where the metal lost its structural integrity. Sealing over that corrosion without prepping the surface is what gives the duct-sealing trade a bad name. We clean it, prep it, and seal it so the fix actually holds.
Last month our crew was called to an original 1963 single-family home in the Croissant Park neighborhood after a routine NADCA-standard cleaning revealed disconnected runs under the slab. We found the galvanized supply duct separated at a seam near the air handler, with the blower motor drawing attic air and rodent nesting material through a two-inch gap. Our techs used a Rotobrush camera inspection to map the failed joints, then sealed all accessible supply and return ducts with mastic and mesh, restoring static pressure and cutting the system’s runtime by over 20% during the following week’s humid stretch.
