How Sheet Metal Duct Fabrication Works
Rigid metal duct fabrication is custom sheet metal work built to the exact dimensions a job requires, rather than pulling a standard size off a shelf. We fabricate trunk lines, transitions, elbows, and branch takeoffs from galvanized steel sheet, forming the metal on a brake and joining seams with snap-lock, Pittsburgh lock, or drive-cleat connections depending on the duct size and pressure class involved. Every fabricated piece is built to match the static pressure and airflow requirements of the connected equipment, which matters because a poorly formed transition or an undersized takeoff creates turbulence that shows up later as noise or reduced airflow at the register.
This kind of fabrication comes up most often when a home's existing duct system does not match new equipment dimensions, when a custom transition is needed to route around structural framing, or when a homeowner wants the durability and airtightness that rigid metal offers over flexible duct for long trunk runs. Metal duct holds its cross-sectional shape permanently, so it never develops the sag or kinking that shortens flex duct's effective service life, and it can be fabricated to fit tight spaces, like a low attic plane over a garage, where a pre-manufactured fitting simply will not fit. All seams and joints get sealed with mastic after assembly, since even a well-formed mechanical joint is not airtight on its own.
In Georgetown's older homes, particularly those built before 1990, we frequently fabricate replacement trunk sections because the original ductwork was built for equipment that has since been replaced with a higher-efficiency unit requiring different airflow characteristics. We also fabricate custom transitions for homes going through a system upgrade where the new furnace or air handler cabinet has different dimensions than the old one, requiring a plenum transition piece that does not exist as a stock part. Fabrication work is priced by the complexity and size of the pieces needed, typically in the 800 to 3,000 dollar range for a project involving multiple custom sections, and we always confirm exact measurements on site before cutting metal, since a transition built off approximate dimensions rarely fits cleanly.
