Hi, We too have similar problem. Attached are some of the pictures of cracked hardy planks around the nails. We reported this problem as part of our 11 month repairs list to our builder but they have not done anything yet. Our house is now 1 and ½ years old. I am trying to contact siding company JamesHardie to check whether this is covered by their warranty. Thanks, Srini Click to View 922.07 KB Click to View 746.97 KB Click to View 746.96 KB
