Popular James Hardie products include:
- HardiePlank® Lap Siding

Factors That Affect James Hardie Siding Replacement Cost
Every home is different, and several factors can influence the final project cost.
1. Home Size
The larger your home, the more materials and labor will be required. Homes with greater exterior wall surface area naturally cost more to reside.

Two-story and three-story homes require scaffolding, additional labor, and more safety precautions, increasing installation costs.

For example:
- Lap siding is generally the most affordable.

5. Dry Rot or Structural Repairs
Once old siding is removed, contractors sometimes discover:
