Select Wood
Since wood is a product of nature, it can vary from tree to tree, even in the same wood species. Avoid surprises: first test any stain you are considering on an inconspicuous spot to ensure that the color of the stain—in conjunction with the natural color of the wood - produces the color you desire. A disadvantage to having a wooden exterior door is that over time, exposure to the elements can cause the wood to warp, resulting in a break in the door's air-sealing capabilities.
