How to Fix Outside Window Shutters: A DIY Guide

Exterior window shutters can enhance your home’s curb appeal, but they’re also exposed to the elements year-round. Over time, this exposure can lead to damage. If you’re wondering how to repair your outdoor shutters, we’ve got you covered with this step-by-step guide.

Assessing the Damage

Before starting any repairs, carefully inspect your shutters. Look for signs of rot, cracks, or loose joints. Determine whether the damage is localized or if the entire shutter needs replacement. For minor issues, a DIY repair can be a cost-effective solution.

Gathering Your Tools

To fix your outside window shutters, you’ll need:
• A putty knife
• Automotive body filler
• Sandpaper
• Exterior primer
• High-quality exterior paint
• Paintbrush or roller
• Protective gear (gloves, safety glasses)

Repairing Holes and Cracks

1. Clean the damaged area thoroughly and remove any loose debris.
2. Mix the automotive body filler according to the manufacturer’s instructions.
3. Use a putty knife to apply the filler, ensuring it’s slightly overfilled.
4. Allow the filler to set completely.
5. Sand the repaired area smooth, blending it with the surrounding surface.

Priming and Painting

1. Apply a coat of exterior primer to the repaired area and let it dry completely.
2. Sand the primed surface lightly for better paint adhesion.
3. Paint the shutter with high-quality exterior paint, matching the original color.
4. Apply multiple thin coats for best results, allowing each coat to dry between applications.

Addressing Loose Joints

If your shutter has loose joints:
1. Remove the shutter from the house.
2. Clean out any debris from the joint.
3. Apply wood glue to the joint and clamp it tightly.
4. Once dry, reinforce the joint with a weather-resistant screw if necessary.
5. Fill any visible screw holes with wood filler, sand, and paint.

Preventative Maintenance

To extend the life of your repaired shutters:
• Clean them regularly to prevent dirt buildup.
• Inspect annually for signs of wear or damage.
• Touch up paint as needed to protect the wood.
• Consider applying a weather-resistant sealant for added protection.
