What Is Duct Sealing?
Duct sealing closes leaks in HVAC ductwork and its connections so conditioned air is less likely to escape through gaps or poorly sealed joints. Leaks can occur around seams, fittings, connections, access panels, or other points in the duct system.
The appropriate sealing material depends on the duct construction, location, and type of joint being sealed. Accessible leaks can be easier to address than concealed sections, and the system may need inspection before the work begins. Customers should identify any known airflow problems or accessible duct areas where leakage has been noticed.
What's Included in Duct Sealing
Sealing scope depends on where leaks are found, how accessible the runs are, and whether insulation or supports also need attention. Common work includes:
- Inspection of accessible joints, boots, and takeoffs for air leaks
- Sealing with mastic or approved tapes suited to duct material
- Reattachment of loose flex connections where practical
- Attention to return leaks that pull attic or crawlspace air into the system
- Notes on sections that are too damaged for sealing alone
- Coordination notes when cleaning and sealing are booked together
- Basic airflow observations after major leak points are closed
Use Serve Kei to book local duct sealing help. Hard-to-reach runs, insulation repairs, or replacement sections can be called out in the quote before work proceeds.

Frequently Asked Questions
Straight answers before you request an quote for duct sealing.
Is sealing the same as cleaning?
No. Cleaning removes debris. Sealing stops air leaks. Many homes benefit from clear thinking about which problem they have.
Can you seal ducts inside walls?
Only where access exists. Closed cavities may need a different approach.
Will my bills drop?
Reducing leaks can help systems run more effectively. Results vary with how leaky the ducts were and other home factors.
Do you use mastic or tape?
Partners choose materials suited to the joint and code-minded practice. Ask if you have preferences.
Should sealing come before cleaning?
Sequence depends on findings. Serve Kei and your partner can recommend an order.
