Identify What the Trim Is Attached To
A damaged board can sit over sheathing, masonry, a door frame or another substrate. The attachment condition should be understood before replacement so the new trim is not fastened into deteriorated material.
Local Repair Depends on Matching the Existing Shape
Width, thickness and profile determine whether a new section can blend with older trim. Paint buildup and previous repairs can make nominally identical boards appear different.
For broader outdoor woodwork, see Exterior Carpentry.
Rot Behind the Face Board Changes the Project
Soft material can extend beyond the visible edge. The repair area should be opened far enough to reach sound material within the approved scope. Extensive hidden deterioration can move the work into a larger exterior-repair project.
Joints and Finish Protect the New Work
Suitable sealant, flashing relationships and finish coating help protect exterior trim, but they are not substitutes for a correct substrate. After carpentry, Exterior Painting can complete the finish.
