I spent $12,000 with National Home. The installation was a mess. I've since had two other companies comment on the installation of Hardie siding and both were really surprised - they both said "normally National does really good work". A lot of my project was installed incorrectly but my PM talked it away. Less than a year later, it looks splotchy and I'm worried about the areas that are not installed per Hardie spec. I wish I'd just had my wood scraped and painted instead of "upgrading" to Hardie board. I'd love National Home Improvements to make this right so I can revise my review. I want to be a fan.
