Answer: A house with wood siding must be repainted at least every five to seven years, or as soon as the paint finish begins to deteriorate
If you want to keep your wood siding in good condition, looking good, lasting for decades and avoid expensive repairs it is absolutely necessary that you maintain regular up-keep and maintenance.
Here is how to protecting your wood siding:
Wood must be properly finished with a paint, stain, or clear sealer. These materials act as a barrier, preventing water from coming into direct contact with the wood. If the wood becomes unprotected, it becomes susceptible to rot and decay caused by moisture. Additionally, wood expands and contracts with normal changes in humidity and temperature. These fluctuations can cause paint to chip and crack, and over time it puts stress on caulked seams around windows, doors, and at corners. If the caulk separates and fails to keep out moisture, wood rot may develop. So, caulk all joints with a high-grade 50-year, paintable silicone or polyurethane product to prevent water from getting behind the siding. Caulk any joint that allows this to happen.
Oil stain finish, expect three to five years of lasting quality.
Clear sealers prevent moisture damage and allow wood to retain its natural color, but they must be reapplied at least every two years.
