Simple Guide: How to Repair Wood Siding

Wood siding gives homes a classic look, but over time it can get damaged. Consulting a siding contractor can be helpful when assessing repair needs. Fixing it quickly helps keep your house looking good and prevents worse problems. This guide will show you how to repair different types of damage step by step.

Step 1: Check for Damage

Before starting repairs, inspect your siding closely. Look for:

• Cracks: Small lines on the surface that may grow if not fixed.
• Rot: Wood that looks discoloured, soft, or crumbly from moisture.
• Dry Rot: A fungus that damages wood from the inside, even if the outside looks fine.
• Warping: Wood that bends or twists because of heat, water, or humidity.

Once you know the problem, you can choose the best way to fix it.

How to Fix Cracked Wood Siding

Cracks can let in water and cause more damage. Here’s how to repair them:

1. Clean the Crack: Use a wire brush to remove dirt and loose wood.
2. Fill the Crack: Use exterior wood filler. Smooth it out with a putty knife.
3. Sand the Area: Once dry, sand it so it’s even with the rest of the siding.
4. Paint or Stain: Match the colour to protect the repair and blend it in.

How to Fix Rotted Wood Siding

Rot spreads fast and needs quick attention:

1. Cut Out the Rotted Part: Use a saw to remove all soft, damaged wood.
2. Treat the Area: Apply a wood hardener to stop further rot and strengthen the area.
3. Add a New Piece: Cut a new board to fit the space. Nail or screw it in securely.
4. Seal the Edges: Use exterior caulk around the new wood to keep water out.
5. Prime and Paint: Add primer and paint to match the rest of the siding.

Tip: Make sure the area is dry before using filler or hardener.

How to Fix Dry Rot

Dry rot can be hidden. To find it, press a screwdriver into the wood—soft spots mean damage.

1. Remove the Bad Wood: Carve out the affected area.
2. Use Epoxy Filler: Fill the gap and smooth it with a putty knife.
3. Strengthen the Wood: Apply a wood hardener to protect it.
4. Finish the Surface: Sand it smooth and then paint or stain.

Helpful Tip: Reseal or repaint your siding every few years to protect it from moisture.

How to Replace Badly Damaged Siding

Sometimes repairs aren’t enough. Here’s how to replace full sections:

1. Take Off Old Boards: Use a pry bar to gently remove the damaged boards.
2. Install New Siding: Measure and cut new pieces. Attach them with rust-proof nails.
3. Seal the Joints: Use caulk to fill in gaps and prevent leaks.
4. Prime and Paint: Finish with matching paint for protection and a uniform look.

Conclusion

Repairing wood siding helps your home stay strong and look great. By fixing cracks, rot, or dry rot early, you can avoid costly damage. With basic tools and some time, you can keep your siding in good shape for years.
