Duct Repair in Chalmette,  LA

• Rooms that never match the thermostat.
• High bills with an AC that runs constantly.
• Dust and a humid, stuffy feel even with the system on.
• Ducts sweating in hot attics, dripping onto insulation.
• Crushed, kinked, or disconnected flex duct.

Most homes route ducts through an attic that bakes all summer. The heat dries out old mastic and tape until joints leak, and humidity condenses on uninsulated runs and breeds mold. Every leak dumps cooled air into the attic and makes the AC work harder — sealing and insulating those runs is one of the highest-return fixes in this climate.

We inspect the full duct system, find leaks and disconnects, and seal joints with mastic and metal tape — never cloth duct tape, which fails in Louisiana heat. We re-secure sagging runs, replace damaged sections, and insulate ducts that sweat.

• Duct inspection / leakage check: $80–$150
• Targeted sealing & minor repairs: $350–$900
• Larger re-runs or replacement: quoted after inspection

You approve a written price first, and sealed ducts often pay for themselves within a couple of cooling seasons.

We cover neighborhoods throughout St. Bernard and the rest of 70043 across St. Bernard Parish — plus nearby Arabi and Meraux.

How do I know my ducts leak?

Uneven rooms, high bills, and dust are the signs; an inspection confirms and locates them.

Seal or replace?

Most homes need sealing and insulation; we replace only crushed or failed sections.

Is it worth it?

Cutting 20–30% duct loss is one of the fastest ways to lower a summer bill.

Will it help humidity and dust?

Yes — sealing keeps humid attic air, dust, and moisture out of your system.
