How much does it cost to seal leaky ductwork?

In the long term, sealing your air ducts will help keep your home energy efficient, save you money, and provide many other benefits. Treat the cost of sealing air ducts as an investment and not as an expense. The disadvantage of air-sealing your own ducts is that there may be places that are nearly impossible to reach within the air duct system. The more time a technician spends in your home checking ducts and the more sealant your home needs, the more you can expect to pay for sealing Ducts.

Sealing air ducts is the process of eliminating any cracks, loose connections, or holes in the air ducts in your home. Having your ducts properly sealed can balance the air temperature in your home, as air can reach each room, creating a more comfortable living space. If the duct sealing professional has to cut a wall or if there are leaks throughout the system, the job will take longer and cost more. Sealing ducts prevents dust and other outdoor particles from passing through the house through the grilles of ventilation.

The additional costs amount to 40 percent of total heating and cooling costs, demonstrating the importance of proper air sealing. It's not as efficient as Aeroseal and can take longer, increasing labor costs for your duct sealing project. Air leaks around pipes, ducts, or electrical wiring through walls and ceilings will be sealed with putty. To take your air sealing to the next level and further minimize air leaks, you can install an insulation system for ducts.

Other areas, such as attics and mezzanines, can be difficult to access, increasing the costs of sealing air leaks. If you want to seal the ducts yourself, you can use aluminum adhesive tape and a sealing putty to fill in the gaps or holes. Rigid foam, spray foam, or caulk will be used to seal exterior walls, roof, or foundations to provide a layer of protection against humidity and prevent leaks.
