Whether it's your palatial estate in the countryside…. or a personal palace in an original Baltimore row home, Natural Stone is a critical feature of many New & Historic residences. While durable, the physical properties of the stone alone are not enough to survive the ravages of time and perform most effectively. Structural stone must be properly anchored, installed and maintained to maintain beauty and stability against weather & exposure. The Marble Mason is the most highly trained of all trowel tradesman. HILGARTNER exclusively uses Marble Masons to install our work; to provide the highest quality of service our staff are our employees and not sub-contractors.
