What it is
A mobile service installing, modifying and repairing sheet metal ductwork in homes and small commercial buildings. You work at the customer's site and take on overflow from larger contractors.
Your first three steps
- Check the trade certification rules in your province and any apprenticeship hours you may need
- Buy or borrow core hand tools, snips and a ladder, and get insurance quotes
- Contact local HVAC and renovation firms and offer to take on overflow or a trial job
Who pays
HVAC companies, general contractors, renovators and some property managers.
How it makes money
Day rate, hourly rate or fixed price per job, usually invoiced to the contractor. Steady relationships with a few firms can fill your calendar, and spring and autumn are often busy.
Skills that help
- Hands-on sheet metal installation and sealing
- Reading mechanical drawings
- Reliable timekeeping and working with other trades
Watch out for
- Trade certification may be required, and gas or heating work often needs separate licensing, check with your provincial regulator
- Commercial general liability insurance, and WCB/WSIB coverage if you hire (rules vary by province)
- Late payment from contractors, so agree payment terms in writing
- Working at heights and in tight attics or crawl spaces, so plan for safety
- Winter slowdowns and weather delays on some jobs
