In the picture to the right you can see the Hardie Plank is faced nailed with a headed nail. This will cause the siding boards to eventually crack. James Hardie states that if you must face nail, a finish nail is to be used.

Another common issue that many homeowners don’t know is James Hardie does NOT want the siding joints to be caulked. Instead install flashing plate under the joint to prevent water intruding. This also helps making your exterior low maintenance by not having to re-caulk the joints often.

Installing James Hardie plank siding incorrectly can lead to various issues that compromise the integrity, performance, and appearance of the siding and the overall structure. Here are some potential consequences of improper installation:

  1. Moisture Infiltration: Improperly installed James Hardie plank siding may allow moisture to infiltrate behind the siding, leading to water damage, rot, and mold growth in the underlying materials such as sheathing, studs, and insulation. This can compromise the structural integrity of the building and create health hazards for occupants.
  2. Warping and Buckling: Incorrect installation techniques, such as inadequate fastening or improper spacing, can cause James Hardie plank siding to warp, buckle, or bow over time. This can result in unsightly gaps, uneven surfaces, and compromised weather resistance, detracting from the appearance and performance of the siding.
  3. Cracking and Splitting: Failure to properly handle and install James Hardie plank siding can cause it to crack, split, or break during installation or shortly thereafter. This can result in aesthetic defects, structural weaknesses, and potential water infiltration points that compromise the durability and longevity of the siding.
  4. Poor Aesthetic Appearance: Improperly installed James Hardie plank siding may result in visible defects such as uneven seams, misaligned courses, or inconsistent joint spacing. These aesthetic flaws detract from the appearance of the siding and diminish the overall curb appeal of the building.
  5. Voided Warranty Coverage: James Hardie offers warranties on its siding products, but these warranties may be voided if the siding is installed improperly. If issues arise due to incorrect installation, the homeowner may be responsible for the cost of repairs or replacement, rather than being covered by the manufacturer’s warranty.
  6. Safety Hazards: In extreme cases, improper installation of James Hardie plank siding can pose safety hazards for occupants and bystanders. For example, siding that is not securely fastened or supported may become dislodged during high winds or storms, posing a risk of injury or property damage.

Overall, it’s essential to ensure that James Hardie plank siding is installed correctly by following the manufacturer’s installation guidelines and recommendations.
