Many homes in the Town of Concord, where I do remodeling, have free standing, cast iron radiators. Recently there has been a large push toward refurbishing old radiators.

Many of these beautifully decorative iron radiators that are often buried under layers of paint. Old, chipped paint is not only an eyesore but it also reduces the heating efficiency of the radiator.

Depending on the type of radiator you have the process of refurbishing old radiators might be a do-it-yourself project.

Lead Paint Warning

WARNING – Many of these beauties were painted years ago with lead paint. Consider getting a test kit before taking on any stripping, sanding or wire wheeling.

This should be an outdoor project to avoid air borne dust. Use high temperature paint.

Professional Sandblasting and Painting

Locally there are companies that specialize in refurbishing radiators.

These companies typically charge an average of $20 per fin, or section. these companies typically remove the radiator and take it back to their shop to refurbish it. At the shop they will disassemble, sand-blast and powder-coated your radiator.
