Select wood species which are naturally decay resistent, or use sealants for protection. When replacing wood in an existing situation, it is always best to also prime the back side of the wood. Woods can be treated with stains, heavy body stains, solid stains, and a variety of paints. The more pigment a material has, the better its resistance to solar breakdown. These materails are generally inert, and if properly applied give long life with few maintenance requirements.
Improper installation can generate the same problems as any improperly installed material.
Annually verify that all joints are sealed, that any damage to the surface is professionally repaired and ascertain the material is performing as originally intended. If problems are noted, contact the manufacturer's material representitive and have them review the service with you and evalluate the installation. Immediate corrective action is always less expensive than a major replacement of the finish and substrate.
