Four-year-old Biltmore, Campbell, Smith Restorations of Asheville has built a nationwide and international reputation for restoration and preservation of artwork. When the firm was established in 1982, it was jointly owned by Biltmore Co. and Campbell, Smith of London. Biltmore Co. recently bought out the London side to become sole owner. While the company has taken on restorations as small as $250, it has also taken on some of the nation's largest restoration jobs. For example, the company spent two and a half years on the $2.3 million restoration of the Pennsylvania State Capitol rotunda in Harrisburg, as well as state capitol projects in Texas, New Jersey, Alabama, and Tennessee.
