How to Fix Damaged Fiber Cement Siding

House in Maryland with fiber cement siding

Fiber cement siding is renowned for its durability and sleek appearance, but even the toughest materials face wear and tear when constantly exposed to the elements, stray baseballs, and relentless woodpeckers. Before you grab your toolbox, explore some common siding issues, potential DIY fixes, and reasons to call in the pros.

Identifying Common Siding Issues

Fiber cement siding is tough but not indestructible. Here are some of the most common issues you may encounter:

  • Cracks and holes caused by accidental impacts, such as flying debris during a storm or a wayward baseball
  • Loose or gapping panels, often resulting from a shoddy installation or deteriorating fasteners
  • Warping and buckling as a result of extreme weather or improper installation
  • Moisture damage, which manifests as swelling, mold growth, discoloration, or rot in the underlying structure

DIY Siding Repair Tips

If you’re confident in your abilities, here are a few minor siding repairs you can perform yourself:

  • Patch small cracks and holes: Remove dirt and debris with a soft brush or cloth. Apply a cementitious patching compound designed for fiber cement siding. Overfill the crack or hole slightly, as the material shrinks when it dries. Once dry, sand the patch smooth and flush with the siding surface. Finish by painting over the patch with color-matched exterior paint.
  • Replace individual panels: Carefully remove the damaged piece using a pry bar and cut a new panel to size. Secure the new panel with corrosion-resistant nails or screws, making sure to attach it to the studs for a solid hold. Seal the edges with exterior-grade caulk and repaint if necessary.
  • Fix loose panels: For panels that are slightly loose but still intact, re-nailing may do the trick. Use galvanized or stainless-steel nails to secure the panel in place. Check surrounding panels for similar issues and reinforce them as needed.
  • Caulk gaps or seams: Check your siding for deteriorated seams. Use a high-quality, exterior-grade caulk to seal any gaps you find, especially around windows, doors, and edges.

When to Call in a Siding Repair Professional

While some fixes are manageable on your own, certain situations require a professional touch. Here’s when it’s time to call a siding contractor:

  • Widespread damage: If you’re dealing with multiple damaged panels or large cracks, DIY repairs might not hold up.
  • Underlying structural issues: Buckling, warping, or moisture infiltration often indicate deeper problems behind the siding. Professionals can identify and fix the root cause.
  • Warranty concerns: Improper repairs may void your siding’s warranty, leaving you responsible for future problems. Professional contractors ensure that repairs meet manufacturer standards.
  • Aesthetic restoration: Matching paint and texture can be tricky for DIYers, but skilled siding pros can make your repairs nearly invisible.
