How do you know when your deck needs to be replaced completely versus simply replacing the deck boards and rail? Experience tells us the life expectancy of the wood structure is somewhere betweeen 20 – 30 years depending on how it was constructed and maintained.
Once your deck hits the 20 year mark, it would be a good time to have a professional come out and assess the wood itself, the method in which it was fastened, and the supports that carry the load. There are certain conditions that can determine the longevity of the deck such as the soil and the grade of the land. Soil and erode over time and the footings can be exposed which makes the integrity of the structure weaken considerably.
Wood decks need to be sealed either with paint or stain to keep it from the harsh weathering of the sun. In addition, building codes change every 2 – 4 years on how decks are to be constructed and fastened. There are times that simple enhancements can be made to your existing deck to bring it up to the current building codes for safety concerns.
