Cost of a Duct Sealing in Phoenix
April 20, 2022
Duct sealing is a crucial part of maintaining temperatures in your home and ensuring that it stays clean from dust at the same time. Having leaky ducts can reduce the efficiency of your heating and cooling system by as much as 20% and can become a pricey issue if left untreated.
Beyond higher energy bills, leaky ducts can also result in what is known as “backdrafting,” where pollutants and gasses like carbon monoxide leak into living spaces instead of being filtered out safely.
The price of sealing or resealing your ducts can vary, usually between $1,650 to $2,000+. Other factors play into how expensive this service could be, including:
- The Size of Your Home
- Accessibility of Ductwork
- Sealant Options
- Material Costs
We’ll break down how these factors contribute to the overall price of sealing your ductwork, along with the most common solutions that may be presented to you by your contractor.

The Size of Your Home
The size of your home has an important effect on the efficiency of your ductwork.
If the ducts are too small in size, your cooling and heating system will struggle to move air through the smaller ducts to the vents that release into your home. Pressure and rapid temperature changes cause strain and damage to improperly sized ducts, causing cracks and warps that leak and need a sealant or even replacement.
On the other hand, there’s the potential for more significant separation from warping between ducts with larger ducts. More ductwork means more likelihood of large cracks that need sealant due to the extra surface area. Therefore, the cost of labor and materials can also be higher. In the case of poorly designed or installed ductwork, the system may need total replacement instead of sealing and resealing ducts. Entire system replacement can better fit the needs of your home and wallet in the long term.
Accessibility of Ductwork
Sometimes the ducts that need sealant can be difficult to reach, increasing the time required for a completed job. For example, it is common for some ductwork to be behind barriers a technician must cut into, such as hallway walls, ceilings, or floors. Removing and replacing parts of your home will take additional time and specialized labor, which can raise the prices of your duct sealing job.
There are a variety of ways to fix leaks in your ductwork. Depending on the location of your ductwork in your home and the type of leaks they have, different types of sealant may be more beneficial.
Foil tape, an external sealant, is a special type of tape that is foil-backed and heat resistant, allowing it to be used on small leaks to keep heat trapped inside of your ductwork to minimize leakage and allow air to travel to where you want it to go inside your home. It is useful for external small holes or cracks or to wrap around connected pieces of pipe for extra support. Due to being an external sealant, this is a potential solution for visible and easily accessible piping.
Mastic is another kind of useful external sealant. It’s a rubbery cement used for slightly larger cracks in ductwork. It can be used with mesh tape for larger areas, providing a sturdy and long-term seal. This sealant is also used on easily accessible external openings. Finally, there is Aeroseal, which is an internal sealant pumped into your ducts. It seals cracks and openings from the inside of ducts, especially those not visible to the human eye. It’s the most expensive of these three options but is generally expected to last up to 40 years after application and provides internal support to your ductwork.
Depending on the kinds of needs your contractor will have and the complexity of the job, they might require more materials in order to complete it, increasing the cost of the duct sealing.
As mentioned above, different sealants can change the cost of your sealant job. Replacing and repairing drywall or flooring that may need removal can drive up prices depending on how invasive the necessary work has to be.
In some cases, a contractor may also advise the total replacement of your ductwork. Replacing all the ductwork is more expensive as it will require removing old piping and replacing it with new, plus any labor costs. However, it can be the most effective and efficient solution if deemed necessary. Whatever the solution may be, all will require what is known as a blower door test, a diagnostic test that a contractor conducts using air pressure to measure the severity of the leakage and find the location of the damage in your ductwork.
