Paintings and Icons Conservation & Restoration Services

Helen Sviderskis
Born in Moscow, Russia and now based in Florida, Helen Sviderskis was educated and trained in the Moscow All-Russian Scientific Restoration Center founded by academician Igor Grabar.
Vast museum experience in ancient icon painting techniques and practical knowledge of the physical condition of historic and artistic works allows Helen to be successful in the field of conservation and restoration of Russian Icons, Old Masters, all periods of European and American easel painting and poly-chrome sculptures.
Helen is well versed in traditional techniques which have long been used by Russian restorers. For instance, Helen employs a unique, museum method using sturgeon glue for icon-panel painting consolidation. Adapting it in her conservation practice, Helen has salvaged dozens of highly valuable icons from destruction.
Use of museum conservation methods and materials make it possible to provide quality consolidation: flattening a peel and flaking paint layers on panel, canvas, wood and metal. Relining, re-gilding and re-varnishing processes are also offered. Helen ensures careful test cleaning and removal of layers of grime, muddy varnish and the over-paint without damage to the original painting. Helen also executes meticulous in-painting and minimal retouching, using only finely ground pigments and applicable mediums.

With over three decades of experience in conservation and restoration, Helen has professional expertise and in depth knowledge that encompasses the technical aspects of restoration.
