Furnace Duct Repair

Furnace Duct Repair

Stop heating leaks in your Metro Detroit home.

When winter hits 0°F, you need every BTU reaching your rooms. We repair cracked seams and separated joints in sheet metal ductwork throughout Detroit's older homes.

Using Pittsburgh locks and TDF flanges, we create airtight seals that last. For basements prone to flooding, we install galvanized steel risers that won't rust like flex duct connectors.

Common fixes include reattaching collapsed trunk lines in Rochester Hills colonials and sealing leaks where ducts pass through uninsulated crawlspaces in Ann Arbor ranches.
