How much does it cost to install exposed industrial-style ductwork in a Toronto loft?

Exposed industrial-style ductwork in a Toronto loft typically costs $5,000 to $15,000 for a complete installation, depending on the size of the space, the type of duct material, and how much of the existing system can be reused versus replaced. This style has become increasingly popular in converted warehouse lofts in Liberty Village, the Distillery District, Queen West, and King West, as well as in basement renovations across the GTA where homeowners want that raw, open-ceiling aesthetic.

The key cost driver is the material. Spiral round duct is the go-to choice for exposed installations because of its clean, factory-finished appearance and minimal air leakage at the spiral seam. In the GTA market, spiral duct runs $10 to $25 per linear foot installed, compared to $8 to $20 per linear foot for standard snap-lock round duct. For a typical 1,200 to 1,800 square foot loft space, you might need 80 to 150 linear feet of trunk and branch duct, plus fittings, registers, and hangers. The fittings — elbows, tees, reducers, and takeoffs — add significantly to both material and labour costs because every joint is visible and must be finished cleanly.

Finishing quality is what separates a $5,000 job from a $15,000 job. A basic exposed duct installation using standard galvanized spiral duct with visible hangers and simple round registers sits at the lower end. A premium installation with powder-coated or painted ductwork, architectural-grade round diffusers, custom-fabricated fittings, and concealed mounting hardware pushes toward the higher end. Many Toronto loft owners also opt for matte black or brushed steel finishes, which adds $2 to $5 per linear foot for painting or powder coating. Every joint, seam, and hanger is on display, so the sheet metal contractor needs to work with a level of precision and care that goes well beyond a standard concealed installation.

There are practical considerations beyond aesthetics. Exposed ducts in conditioned spaces do not need insulation the way attic or crawlspace ducts do, which saves on material costs. However, exposed supply ducts carrying cold air conditioning in summer can develop condensation in humid conditions, especially in lofts with large windows and limited climate control. Applying a thin layer of internal duct liner or ensuring adequate dehumidification prevents dripping condensation and water stains on floors and furniture. Noise is another factor — exposed ductwork transmits system noise directly into the living space. Using larger duct sizes to reduce air velocity, installing flexible connectors at the air handler, and adding internal duct liner where needed all help manage noise levels.

If your loft has existing ductwork that is currently concealed above a drop ceiling, removing the drop ceiling and cleaning up the existing duct system is typically less expensive than a complete new installation — expect $2,000 to $6,000 for cleanup, resealing, repainting, and new registers. For a ground-up exposed installation in a new loft or major renovation, budget $8,000 to $15,000 for a professionally designed and finished system.
