On January 15, 2019, after months of concerns, we hired an inspector who specialized in Hardie installation and materials. A full inspection was conducted and a report was generated (see below). This report was emailed to Focal Point Homes on 1/18/2019.
On February 19th, the original subcontractor that installed our James Hardie siding emailed us and stated that after speaking with James Hardie (The James Hardie Rep/inspector that came to our house on February 13, 2019) they both have decided to replace the Hardie siding on our home.
