Our foothills home is in an area where fire is a concern. We had Gravina's remove the vinyl and replace it with fire resistant Hardie Board. Everyone I met from Gravina's, including Crissy, Mike, and Jim Gravina, seemed determined to ensure we made a wise and fully informed decision. The installers are employees of Gravina's, not contractors. These are seasoned workers with excellent skills. We were especially impressed by their willingness to go above and beyond the basic requirements of the job as they did the installation. We could not be more pleased or recommend Gravina's more highly.
