How to Repair Exterior Wood Shutters

By: Danny Lipford

Exterior wood shutters take a lot of abuse from the elements. Over time this can cause the wood in shutters to rot or the joints in the shutter frame to come apart. Here’s how to repair shutters on your home.

How to repair a rotten shutter:

  • Remove all the rotten wood from the damaged area of the shutter using a chisel or putty knife.
  • Mix up a small amount of two-part auto body filler, available at auto supply stores, using the recommended proportions.
  • Use a putty knife to fill the hole in the shutter with automotive body.
  • Smooth the filler flush with the surface of the shutter, and allow it to set.
  • Smooth the surface with sandpaper.
  • Prime the spot with exterior primer, allow to dry, then paint the shutter with a high quality exterior paint.

How to repair a shutter joint:

  • Hold or clamp the shutter frame together, making sure the louver slats are properly positioned in the slots.
  • Drill a pilot hole through the shutter stile and into the shutter rail.
  • Use a drill to insert a corrosion resistant screw in the hole to secure the frame together.
  • Prime and paint the screw head to keep water out and hide the repair.

    Hi, Helen,
    Danny says, “Put two clamps on the front and one clamp on the back. Good luck!”

    Our exterior wood louvered shutters were prepped for paint two years ago but just noticed that some rail and stile joints have loosened. How would a pipe clamp be positioned with the intersecting shorter clamp? The shutters range in height from 40″ to 5′. I am a 72- year old non-Handyman that will attempt to rescue nine pairs of shutters.
    I am most appreciative of any direction offered.
    Most sincerely,

    Is there anything you can spray on the back of louvered shutters to keep the louvers from coming loose? Maybe something clear.
