Correct installation over proper substrates is necessary to profit from cedar’s natural attributes. Research the appropriate backing materials for your area. Always use stainless steel or hot-dipped galvanized nails of the proper length. Never use electroplated or uncoated nails. These will rust and stain the siding or, worse, weaken the siding and lead to expensive repairs. It’s also a good idea to clean your siding yearly with a stiff broom or brush. Like anything of value, caring for your cedar will keep it looking new for years to come. And with care, it may very well last a lifetime and beyond.
