Painting Restoration and Conservation Services

Some of the Services Offered and What They Mean:

LINING—Dependent upon a large number of factors including age, overly aggressive cleaning and restoration, inferior original materials or environmental damage a painting’s support, typically canvas, needs to be lined with another canvas in order to provide strength and stability to the artwork. Lining on old canvas is sometimes our only choice as the original is just not sufficient enough to support the paint surface any longer. See this painting below an untrained conservator glued it to a wooden support using something like contact cement and the support was not structurally sound so it warped and tore the paint layer from the canvas. The painting was in a delicate state prior to this work and required us to consolidate the flaking paint extensively and move to lining with a new Belgian Linen support and stretching.

RELINING—Relining is the removal of an old lining canvas that had been put in place at some point in the past to provide support for your original painting's canvas. When this lining canvas begins to fail or has suffered damage it needs to be replaced.

CLEANING—Cleaning your painting does not usually include removing the old layer(s) of varnish. Cleaning typically involves the removal of smoke accumulation, oil and grime built up over years of display. Sometimes your painting will have mold and other contaminants that will have to be removed in order to conserve your artwork for the future. Cleaning will expose the original brightness and clarity of the colors and remove harmful contaminants.

REMOVING VARNISH—Varnish removal is a difficult and very stressful operation on a painting and should be carefully considered. However, having said that it often opens a window into the original colors and appearance of your artwork that no other treatment can. Some of the original varnishes used in decades past are not always good for conservation purposes and can be detrimental to the stability of your painting. Many old paintings have a look that the aged varnish provides that you might find attractive. Removing the varnish will be a total transformation of the painting and should be considered carefully. Removing the varnish is like starting over and brings the painting back close to what it looked like on the artist's easel. Removing the varnish can expose old repairs, touch ups, figures painted over by a previous restorer, there are many secrets waiting to be found underneath decades of varnishing and re varnishing. Some restorers in the past used mood varnishes to give a mood or an antique quality to a painting according to their tastes that I often find to be obscuring to the original work. Notice below once the painting is stripped of the varnish, lined, patched, "oiled out" to bring back the original colors it is touched up and ready for varnish.

CONSOLIDATION--Consolidating a painting involves using materials to bind loose, flaking paint or rejoin the paint and ground to the textile (canvas). The materials used in consolidation vary from wax/resin compounds(traditional recipe) to more conservation minded treatments like Beva solution and film. The painting below suffers from flaking paint throughout the painting and requires a liquid solution consolidant applied to the entire painting to stop the losses. Once consolidation is complete the painting is touched up and varnished.

OILING OUT A PAINTING--Oiling out a painting reinvigorates the dry colorless quality of the aged paint layer and gives it the original depth and true color values of what the artist intended.

VARNISHING—Today’s varnishes are really clear and quite thin but have been formulated to be easily removed in the future and to put little chemical strain on your painting.

TEARS, HOLES AND SCRATCHES—almost any cut or puncture can be repaired and restored. Believe me we have seen it all. Frame Repair—We can also restore your polychrome frames no matter the finish or design.

STRETCHING, RE-STRETCHING, STRETCHER REPAIR, WEDGES—We will modify and design an appropriate stretcher for your canvas painting and include newer mechanisms for keeping the textile at the right tension. Many of today’s stretchers come without wedges and many people have forgotten the value of a carefully stretched canvas painting. Many older painting stretchers are in major need of care. We will bring your stretcher up to date while preserving its age and antique qualities.

IN FILL PAINTING, PATCHING, IMPASTO TOUCH-UP—We have extensive experience in patching, texturing and color matching on even the most subtle of artist’ techniques.

Oil, acrylic, gouache, tempura—we work on all supports and mediums including paper and water color in limited circumstances.
