Effective maintenance is crucial for the longevity of wood poles. This includes routine inspections for signs of decay, rot, and insect damage, especially at the ground line. Pole reinforcement techniques, such as stubbing, can be used to extend the life of a pole that has experienced decay. Regular checks on guy wires, hardware, and insulators are also essential to ensure the entire structure remains stable and functional. Proper maintenance can significantly extend the lifespan of a wood pole beyond its initial service estimate.
