What Is a Siding Wedge?

Siding WedgeThe use of siding wedges can help prevent rot from deteriorating the siding or clapboard on a home. Dry rot is a common occurrence, and its presence indicates an underlying water problem, according to the University of Massachusetts. Siding wedges work to solve this water problem; however, since the term ‘siding wedge’ is unfamiliar to many, the following attempts to explain what they are, why they’re used, and how to use them.

What Are Siding Wedges?

Siding wedges are wedge-shaped pieces of aluminum designed to be inserted underneath siding or clapboard. Each wedge contains a raised center portion that tapers down toward flat edges. An opening in the center of each wedge allows air to circulate down through the raised central space.

Why Install Siding Wedges?

Tightly installed siding may trap moisture, which can lead to rot. Siding wedges help avoid this. By opening up the space between siding boards, these wedges allow for air circulation and dispersal of accumulated water.

How to Use Siding Wedges

With the help of a flat blade screwdriver, siding wedges are relatively easy to install. Simply use the end of the screwdriver to push each wedge up underneath individual planks. Ideally, this will be done before any final coats of paint are applied to the siding, since installation of these wedges will most likely leave marks otherwise. Wedges should be spaced about 18 inches apart.
