If you’ve been told you have leaky ducts—and most homes do—you may have heard about duct sealing as a solution.

For starters, let’s answer the big question on your mind: Duct sealing costs anywhere from $1,000 to $3,000+ in Florida.

And if you need to replace your ducts altogether (we’ll explain more below), that costs $5,000 to $8,000 on average in Florida.

The price of duct sealing can vary within that range based on the following cost factors:

  1. The size of your home

  2. Labor considerations

  3. Duct sealing vs duct replacement

Duct sealing cost factors

#1: The size of your home

The bigger your home, the more your duct sealing will cost.

See, bigger homes have more vents, which means they also have more ductwork connecting to each of those vents.

Since bigger homes have more ductwork, more labor is needed to check for duct leaks, and often more materials are required to seal (or replace) the ducts.

#2: Labor considerations

The following labor factors could raise the cost of your duct sealing:

  • Hard-to-reach ductwork: If your ductwork is in a hard-to-reach crawl space, it will take longer to complete the job, which raises the cost of the project.

  • Cutting into walls/floors/ceilings to access ductwork: This will raise the cost of your duct sealing project because you’ll have to restore the walls/floors/ceilings. If you have leaky ducts that are hidden behind walls it may be more cost-effective to go with the Aeroseal method.

#3: Duct sealing vs duct replacement

Homeowners in Florida have 2 main options when it comes to fixing leaky ducts:

  1. Sealing ducts

  2. Duct replacement

Sealing ducts (less expensive, but often less effective)

If you can visibly detect leaks or holes in your ductwork, sometimes a tech will use metal tape or mastic sealant to close off the leak.

But here’s the thing: Many homes in Florida have ductwork made of flex material or duct board, both of which are difficult to reliably seal using manual sealing methods.

If you have a large amount of leaks in flex ducts or your ducts are constructed with duct board, manual sealing is probably NOT the best method for you.

Duct replacement (more expensive, but often more effective)

Duct replacement is more expensive than manual sealing methods because it involves more material cost and more labor, but it’s also the most effective way to eliminate duct leaks.

So if a tech inspects notices a large amount of leaks in your ductwork, they may recommend replacing those ducts altogether—especially if the ducts are old, poorly designed or undersized to begin with.
