Step-by-Step Replacement Process
Follow these steps to swap out old siding.
1. Inspect and Plan
Start by checking the damage. Look for cracked or loose boards. Mark the ones to replace. Measure their size. Buy matching Hardie board panels. Planning cuts down on mistakes.
2. Remove Old Siding
Grab your pry bar. Gently lift the damaged board. Pull out nails or screws. Work slowly to avoid harming nearby panels. Remove the whole piece. Clear any debris from the wall.
3. Prep the Wall
Check the wall underneath. Look for rot or mold. Fix any damage with new sheathing if needed. Lay down a weather barrier—like house wrap—for extra protection. A clean wall makes the new siding stick better.
4. Cut New Siding
Measure the gap where the old board was. Mark the new Hardie board. Use a circular saw with a diamond blade. Cut carefully for a snug fit. Double-check the size before moving on.
5. Install the New Panel
Place the new board. Align it with a level. Nail or screw it into studs—every 16 inches. Leave a 1/8-inch gap at the ends for expansion. Lock it into the panel below for a tight seal.
6. Seal and Finish
Apply caulk to seams and edges. This stops water from sneaking in. Paint or prime the new board to match. Check for gaps or wobbles. A smooth finish looks pro.
