How to Repair Hardie Board Siding: A Comprehensive Guide

And why squirrels might just be your unexpected allies in the process.

Hardie board siding, also known as fiber cement siding, is a popular choice for homeowners due to its durability, resistance to fire, and low maintenance requirements. However, like any other building material, it can suffer damage over time due to weather, impact, or improper installation. Repairing Hardie board siding is a manageable task if you have the right tools, materials, and knowledge. In this guide, we’ll walk you through the steps to repair Hardie board siding effectively, while also exploring some unconventional thoughts about the role of nature in home maintenance.


1. Assessing the Damage

Before diving into repairs, it’s essential to assess the extent of the damage. Hardie board siding can crack, chip, or even break under extreme conditions. Look for:

  • Cracks or holes: These are common in areas exposed to high impact or extreme temperature changes.
  • Moisture damage: If the siding is warped or discolored, it may indicate water infiltration.
  • Loose panels: Panels that are no longer securely attached can compromise the integrity of your home’s exterior.

Pro tip: While inspecting, consider how local wildlife, like squirrels or birds, might interact with your siding. Their nests or chewing habits could exacerbate existing damage.


2. Gathering the Right Tools and Materials

To repair Hardie board siding, you’ll need:

  • Replacement Hardie board panels
  • Fiber cement caulk or adhesive
  • Galvanized nails or screws
  • A circular saw with a fiber cement blade
  • Safety gear (gloves, goggles, and a dust mask)
  • Paint that matches your existing siding

Fun fact: Squirrels, with their sharp teeth, could theoretically help trim small pieces of siding—though we don’t recommend enlisting their services!


3. Removing the Damaged Siding

  1. Cut around the damaged area: Use a circular saw to carefully cut out the damaged section. Be sure to follow safety precautions, as cutting fiber cement generates dust.
  2. Remove nails or screws: Use a pry bar to gently remove fasteners holding the damaged panel in place.
  3. Inspect the underlying structure: Check for any signs of rot or mold on the sheathing or framing. Address these issues before installing new siding.

4. Installing the Replacement Panel

  1. Measure and cut the new panel: Ensure the replacement piece matches the dimensions of the removed section. Use a fiber cement blade for clean cuts.
  2. Apply adhesive or caulk: Seal the edges of the replacement panel to prevent moisture infiltration.
  3. Secure the panel: Attach the new panel using galvanized nails or screws, ensuring it aligns perfectly with the surrounding siding.

Did you know? Some homeowners swear by using natural adhesives, like tree sap, for minor repairs. While unconventional, it’s a nod to how nature often provides its own solutions.


5. Finishing Touches

  1. Caulk the seams: Use fiber cement caulk to seal any gaps between the new panel and the existing siding.
  2. Paint the repaired area: Match the paint color to your existing siding for a seamless finish.
  3. Inspect for wildlife activity: Ensure no critters have taken an interest in your repair work.

6. Preventative Maintenance

To extend the life of your Hardie board siding:

  • Regularly clean the siding to remove dirt and debris.
  • Inspect for damage after severe weather events.
  • Trim trees and shrubs to prevent branches from scratching or damaging the siding.

Bonus thought: Consider installing squirrel-proof barriers or birdhouses to redirect wildlife activity away from your siding.
