All ductwork leaks to some extent. Which means all homeowners waste money every month via leaky ductwork (and, yes, that includes you).
In fact, according to Energy.gov, the typical home loses around 30% of conditioned air due to ductwork leaks. Which basically means, for every $100 you spend on heating/cooling your home, you’re throwing $30 in the trash.
The good news is that duct sealing can close off those costly leaks. But how much does that cost? Well, it depends, but the typical cost of duct sealing in Denver ranges from $1,000–$4,000+.
The price you’ll end up paying all depends on:
We’ll explain the 4 factors above and how they affect your final duct sealing cost.
The larger the home, the more duct sealing will cost.
That’s because a larger home typically needs more vents to pump cold/warm air throughout the entire home. And the more vents, the more ductwork to check/seal, which raises labor and material costs.
For example, the cost to seal ductwork in a 5,000 sq/ft+ home could cost up to $1,200 more than a 1,000 sq/ft home with equally leaky ductwork.
The more labor-intensive the duct sealing project, the higher the cost.
More complex duct sealing jobs take longer (which raises the cost of labor), require more materials and might even require special tools that cost more to operate.
Situations that might require more labor/materials/tools than the typical duct-sealing job include:
Two categories of duct sealing include:
Ductwork sealed manually with mastic. Source: Oregon.gov
Manual duct sealing uses either mastic or mastic tape to seal duct leaks. This option is great for sealing large holes in the ductwork and/or to seal connections. This option is generally cheaper than Aeroseal because the materials themselves are cheap and homeowners can typically handle this job themselves.
Manual duct sealing methods cannot find or seal leaks that are hidden in walls and other hard-to-reach areas. This method also relies on the limited visual inspection of the homeowner/tech to find all the tiny holes and cracks in ductwork.

Aeroseal works by injecting aerosol particles directly into the ductwork. This method works to seal 100% of leaks up to ⅝ inches. Because Aeroseal seals ducts from the inside out, it can reach leaks in very hard-to-reach places.
Aeroseal can’t seal larger leaks and is more expensive than manual methods. But remember, to access most ductwork, manual sealing jobs often require cutting into walls, which is expensive when you factor in the repair work and makes the overall price comparable to the AeroSeal method.
Different companies charge different prices for duct sealing. And, typically, the higher-quality companies charge higher prices.
Our advice? When it comes to duct sealing, you don’t want to risk hiring a low-priced contractor. Why? Well, a sloppy duct sealing job can lead to:
Instead, make sure you choose a company that guarantees they will:
