What duct repair St George homes need looks like

Sealing closes gaps in ducts that are intact. Repair deals with ducts that are not. During a pressure test and inspection, we often find sections that have come apart, been crushed under stored items, torn by other trades or pinched during an earlier project. No amount of mastic fixes a duct that is not connected to anything.

Large holes matter for another reason. Holes larger than about ½ inch need to be repaired by hand before aerosol sealing is used, because the spray cannot bridge them. Repair comes first, then sealing, then the retest.

The honest part of duct repair St George homeowners should hear is that the cause often is not a surprise. Storage in the attic, other trades working around the ducts and age all take their toll, and the fix is usually a few specific sections, not the whole system.

Common repairs we find

Disconnected runs: a duct that has pulled off a collar or boot and is blowing into the attic.
Crushed or kinked flex duct: restricts airflow and often starves a room.
Torn duct and failed insulation: lets air escape and allows heat gain.
Failed connections: joints held by cloth tape that has dried out and let go.
Sagging runs: flex duct that has drooped between supports and pinched shut.

Many of these show up as weak airflow vents or rooms that never cool. A test and inspection tell us which.

Repair or replace: how we decide

Condition	Likely approach
A few damaged sections, rest intact	Repair those sections, seal, retest
Many sections failed or the system is undersized	Discuss replacement
Intact ducts with leaky joints	Mastic and foil tape, no repair needed
Hidden leaks behind ceilings	Aerosol sealing after large holes are repaired

Replacement is the larger job and the larger price, which is why we only suggest it when repair cannot do the job. See sealing versus replacing ducts for the full comparison.

Our rule is simple: repair the least needed to get the system working, seal it properly and prove the result with a retest. If we think replacement is the better choice, we explain why with the test numbers in front of you, and you decide.
