Duct Sealing & Repair

When ducts run through a crawl space, leaks and disconnections send heated or cooled air straight into the space under the house instead of into the rooms above. It wastes energy, leaves rooms uncomfortable and puts moisture-carrying air where it does not belong.

We repair and seal ducts in crawl spaces across Nashville and Middle Tennessee. Disconnected runs are reattached, joints are sealed, sagging ducts are supported and the system is insulated so it performs as intended.

What you get

Done right, from the first walk-through

01

Reconnect and re-secure ducts

Fallen or disconnected runs are put back where they belong.

02

Seal joints with mastic and tape

Seams and connections are sealed with proper materials.

03

Support and straighten

Straps and supports keep ducts from sagging.

Ducts are wrapped so they do not sweat or lose heat.

FAQ

Common questions about duct sealing & repair

Do you replace ductwork?

We can replace damaged sections in the crawl space. For full system design or equipment work, we recommend an HVAC specialist.

How do I know ducts are leaking?

Rooms that never reach the right temperature, ducts that hang or lie on the ground and a dusty or damp crawl space are all signs.

Is it a problem if ducts touch the ground?

Yes. Ducts on the ground collect moisture and are more likely to be damaged. We lift and support them.
