Duct Repair & Sealing
What it covers
The work also covers leaking plenums, where the main box at the air handler or furnace can split at a seam or lose its seal at a connection. That kind of damage can happen after vibration, rust, or a hard pull on the connected duct. In kitchens, offices, warehouses, apartments, and restaurants, we also look for crushed flex duct above ceilings or in tight chases where traffic or storage has pressed on it. If a return grille rattles or a room feels weak, check the boot, the collar, and the first stretch of duct.
What we check
What we check
We start at the supply and return runs and trace each section for gaps, loose tape, crushed bends, and ducts that have pulled apart at a joint. In homes and restaurants, those spots can change how air moves through the system and can leave parts of the line working harder than others. We also look at the outer jacket on insulated duct for tears, missing wrap, and wet or loose spots that can let the duct sweat. A crushed flex run needs a close look at the support straps and any sharp turn.
We then check the plenum, the sealed box that connects the equipment to the ducts, for open seams, weak mastic, and spaces around takeoffs. That area can leak air into a closet, attic, or mechanical room before it reaches the rooms or dining area. During the visit, we can use pressure testing and hand inspection to find where air slips out and where a repair should focus. Each register and grille is checked for balance, and a loose return boot is one more spot that can pull dust into the system.

Choices to make
When a duct is crushed, torn, or pulled apart, we look at how much of the run is affected and whether the metal or flex material still holds shape. A short section with a loose joint may be repaired with new fasteners, sealed mastic, and fresh insulation tape. A long run with repeated damage can point to replacement of that section instead. We also check access above ceilings, in attics, and through wall chases, since tight spaces can limit the repair path.
Duct sealing can be the right choice when the pipework is sound but the joints, seams, or plenum edges leak air. If the insulation jacket is torn, we look at whether only the outer wrap needs patching or whether the duct below has been exposed long enough to replace the section. A leaking plenum may need resealing at the cabinet flange or a new connector if the metal is bent or split. We check for tape that lifts at the corners, since peeling seams often show where air escapes.

After the work
After the visit, you know which parts were open, crushed, torn, or leaking, and where the wrap around the duct had pulled back. We may have rejoined loose sections, sealed gaps at joints and plenums, and patched damaged insulation where air was escaping into attics, crawl spaces, or walls. You also have a clear picture of any areas that need a later check. Watch for new dust at registers, bent duct runs, loose hanging sections, or soft spots in the insulation near the air handler.
To keep the system in good shape, keep storage boxes and heavy items away from attic ducts, and avoid pushing into flex runs when you move through the space. Check exposed duct runs after roof leaks, pest work, or any project near the air handler, because a tug or puncture can open a seam or tear the jacket. If you change filters, look at the plenum connection and nearby tape for peeling edges or gaps, and keep drain lines clear so moisture does not sit near the insulation.

Questions
Duct Repair & Sealing: common questions
I found a flex duct hanging loose in my attic, so what are you looking for before you reconnect it?
We look at the full run, not just the loose end. A duct can pull apart at a joint, sag under its own weight, or slip out of a collar. We also check nearby straps, bends, and connections to see why it came loose in the first place. After that, we decide whether the section can be reattached, secured, or needs part of the run replaced.
My bedroom vent barely moves air, and the duct under the insulation looks crushed. What does that mean?
A crushed duct can pinch off airflow and make that room feel different from the rest of the home. We inspect the shape of the duct, the path it takes, and anything pressing on it, like stored items or framing. Then we look at the surrounding insulation and joints to see whether the line can be reshaped, resecured, or replaced in the damaged section.
I can feel air leaking at the seams near my hallway ceiling. How do you tell if the duct needs sealing?
We check the seams, tape lines, and mastic areas where air can escape. Small gaps at joints, elbows, and takeoffs can let conditioned air spill into the attic or wall space. We also look for loose connections and worn sealing material. If the leak is at a joint or plenum connection, we address that spot directly instead of just covering the visible opening.
The insulation on my duct is torn and hanging open. Do you just wrap it back up, or is there more to check?
Torn insulation can point to more than a surface problem. We look for cuts, crushed spots, and exposed areas where the duct jacket may be damaged too. Then we see whether the inner duct is intact and whether any seams are leaking under the torn section. If the insulation is only damaged on the outside, the repair is different than if the duct itself has been compromised.
I noticed air leaking around the metal box where the ducts connect. What is a leaking plenum?
A plenum is the main connection box that feeds air into the duct system, and leaks there can affect several branches at once. We inspect the seams, corners, and joints around that box, along with any disconnected or loose duct connections nearby. Sometimes the issue is sealing material that has failed. Other times the plenum itself has gaps, dents, or separated joints that need attention.
