How to Repair Hardie Plank Siding. The main reason Hardie plank siding has become so popular is because it is so durable. It has the same look as wood and vinyl siding, but it requires far less maintenance and repair than both. Hardie plank siding is made from fiber cement, which makes it very heavy and long-lasting. Hardie plank siding comes with a 50-year warranty. Installing Hardie plank can be more labor-intensive than installing other types of siding. If problems occur that require repair, it will most likely be because of a faulty repair.

Step 1

Prevent installation problems by hiring a qualified and experienced professional to install your Hardie plank siding. Installing Hardie plank is different than installing traditional wood or vinyl siding, so you want to find someone who has extensive experience working with these materials.

Step 2

Make your installer repair any structural problems from insect or water damage before beginning installation. Some bad installations are due to failure to prep the home sufficiently. If the installer doesn't examine the home before getting to work, you should find another installer.

Step 3

Examine the installation of your siding. Hardie plank has specific installation instructions for their product that must be followed.

Step 4

Only use planks that are not chipped or broken. Chips and breaks can occur when transporting these heavy materials. Cut the damage off any siding before installing it.

Step 5

Read over the installation instructions available at James Hardie to make sure your siding has been properly installed (see Resources below).

Step 6

Check out how many nails are used in the boards. In some cases of bad installation, too many nails are used to secure the siding because the sheathing beneath the siding was not installed properly. Nails should not be immediately visible after installation.
