Air Duct Repair & Sealing
Seal the Leaks That Keep Rooms Warm and Bills High
Air duct repair and sealing in Fort Lauderdale fixes the gaps, loose joints, and small tears that let conditioned air leak out before it reaches your rooms. Because the air conditioner runs most of the year here, even a modest leak means the system works harder and some rooms never feel comfortable.
Sealing is different from a full rebuild. We seal accessible joints and connections and repair minor damage; when a run is crushed, torn, or beyond sealing, AC duct replacement is the better fix, and dusty but intact ducts are handled by ductwork cleaning.
What’s included
What Air Duct Repair & Sealing Covers
01
Leaking joints

03
Small gaps and tears
Minor punctures and separated seams in accessible duct are patched where practical.
04

The benefits
Why Sealing Leaky Ducts Pays Off
Air reaches the room
Sealed joints send cooled air to the register instead of leaking it into the attic.
Less wasted cooling
Closing leaks means the system does not run longer to make up for lost air.
Steadier comfort
Rooms that ran warm often even out once the leaks feeding them are sealed.
Targeted and lower cost
Sealing a sound run avoids the cost of replacing duct that is still serviceable.
Our Process
How We Repair and Seal Ducts
-
01
Inspect the runs
We check accessible joints and connections for leaks, gaps, and loose sections.
-
02
Confirm the scope
We separate what can be sealed from what should be replaced and explain it.
-
03
Seal and secure
Joints are sealed with mastic or tape and loose sections are reconnected and fastened.
-
04
Verify airflow
We confirm air is reaching the room and the leak is closed before we leave.
Good to know
Sealing is not the same as replacement
Sealing closes leaks and reconnects joints on a run that is otherwise sound. If the duct is crushed, torn in several places, or the wrong size, sealing will not hold, and we will recommend replacing that section instead.

FAQs
Air Duct Repair & Sealing FAQs
Straight answers about how we work. Don’t see your question? Give us a call.
What is the difference between duct sealing and duct replacement?
Sealing closes leaks and reconnects joints on a sound run. Replacement removes a run that is crushed, torn, or the wrong size. An inspection tells us which one your ducts need.
How do you seal air duct leaks?
We seal accessible joints and connections with duct mastic or metal-backed tape and reconnect sections that have come loose. Cloth tape is not used because it fails in attic heat.
Can sealing lower my cooling bills?
Closing leaks lets the system deliver the air it already makes, so it can help. We do not promise a specific percentage because every home and system is different.
Do you seal ducts inside walls or only in the attic?
We seal the connections and runs we can reach safely, which in Fort Lauderdale is usually the attic, closets, and the air handler. Sealed-in runs may need access we will explain first.
Is sealing done from inside the ducts?
This service seals joints and connections from the outside of the duct. Treating the inside surface of the duct is a separate service, air duct restoration and coating.
Will I still benefit from cleaning if my ducts leak?
Cleaning removes dust; sealing stops air loss. They solve different problems, and many homes do both. A dusty, leaky run can be cleaned and sealed on the same visit.
