Why do i have rotten wood?
Although wood is the most common material used for exterior trim work, it does have several downsides. Wood trim is susceptible to water damage and rot, particularly on raw edges and ends that can't be painted after installation (like where two boards meet) or where they are in contact with the roof. Inside and outside corners of gutters can also be problem spots if there is a leak in the gutter. The photo below highlights some of the areas where we find rot most often.
Rot will occur anywhere water can get to exposed wood. Inadequate or old, split caulking can allow moisture to penetrate and begin the decaying process. This is why we place such a premium on caulking. It is important to replace rotten wood as soon as possible - delay can allow the water to penetrate further and begin damaging structural framing.
