Water is the enemy of your home.
It won't take long for the wood trim around columns, and siding, to deteriorate if water gets in behind the wood.
Most new homes, where wood siding and trim is used, will have gaps where the water gets in behind it. Once the water gets in behind the boards, it just sits there, and damages the wood, and causes the paint to peel. As well, the ends are usually not sealed well, and moister gets into the wood.
Often, re the wood trim, you can't see the worst gaps from the ground, so you need to check for them from a 2nd floor window. The gaps at the one inch wide flat horizontal surfaces are the worst offenders because water that accumulates on the siding above the trim during rain will run down and get in behind the wood.
These gaps need to be sealed with an exterior grade, paint-able caulking product.
If caulking and painting is maintained, then the wood trim could last indefinitely.
The gaps one year warranty issue. After that it's maintenance.
