A small workshop in a garage, bay or low-cost unit that restores cast-iron and other older radiators. You clean, pressure-test, repair and repaint them. You also sell reconditioned radiators and supply replacements for heating pros.
Your first three steps
- Visit a few salvage yards and heating contractors to price used radiators and see what restorers charge in your area
- Find a workshop space and check zoning and lease terms allow sandblasting, painting and heavy items
- Restore three or four radiators, photograph the before and after, and list them locally and on marketplace sites
Who pays
Owners of older homes, renovators, landlords, historic property owners and heating contractors who need a matching radiator.
How it makes money
A fee per radiator to restore a customer's own unit, plus sales of reconditioned radiators, valves and fittings at a markup.
