A wide ranging question in my specialism of conserving and restoring oil or easel paintings on various supports. The answer lies mainly in five areas; financial, sentimental, custodial, and aesthetic.  Quite simply, a decision on whether to restore a painting lies in the hands and mind of the owner/custodian and the weighting given to each of the following areas.

Financial factors: Include the sterling value (£) of the article, the available budget and the cost of restoring and conservation. The value of a painting can be problematic to settle as there are several factors involved in its reckoning. Firstly, insurance valuation for normal purposes (domestic as opposed to museum/gallery situations), this being obtained mainly by viewing an historical analysis of trends in auction prices over several years for a particular artists works or similar items. Then there is the field of probate valuation for purposes of estate dispersal and taxation. Finally we take a realistic look at the actual achievable price for the painting at auction  with access to a suitably hard-headed auctioneer or even a picture dealer. Remembering  that  these figures  may  vary  widely.

But, the most realistic is likely to be the price in today's more specialised auction rooms, bearing in mind the need to have at least two bidders wanting said painting.  So the value of any picture can tend towards the subjective.

Sentimental factors: Such as family connections, family  wishes, individual likes/dislikes, memories and connections of the picture with an area/individual/certain time in one's life. Again a very subjective area and of fruitful of many strongly held opinions. Some thought has to be given to the future of the painting and in whose possession it will remain, this if the owner is approaching the latter end of their life. Naturally we are getting into more personal areas such as who likes or wants the painting which may even depend on its VALUE!

Custodial factors:  An area which applies to individually produced art works.  After all, they are unique, and in many cases the artist is dead so there will be no others produced.  Reference should be made to the history of the artist and their work, the quality of workmanship, his subject and associated appeal factors, all of which, even with middle range works can also affect value and thus increase the custodial responsibility of owning the painting.

An oil painting requires regular inspection - i.e. a spring clean look over to check front, back, frame and hanging safety, position (e.g. not over heat) and light exposure (e.g. not in direct sunlight).  In the process note should be taken of overall appearance - e.g. even surface coating, correctly stretched canvas, no holly berries or wedges slipped into the canvas and stretcher gap.  Any doubts should be checked with a paintings restorer even by telephone just to avoid the onset of later problems.

Aesthetic:  So many aspects such as visual pleasure, mental response, memory connections fitting to ones psyche, interior decoration and general added quality of life.  Paintings are an artist's expression of a response to a view, a subject, a colour, a shape and many other matters.

  We choose generally, to have paintings that we like in our home surroundings, hence a picture has to harmonise or 'go' with our personal style, even perhaps to match a particular philosophy in life.

Of course, one can choose particular artists work solely for investment and anticipated increase in value which brings us neatly back to finance.

Naturally the owner of a painting will normally think about conservation only when some form of damage has occurred.  The procedure is to get advice from a paintings restorer in the form of an inspection, written report of condition and procedures required together with an estimate.  Then following the above thoughts, and with regard to the available budget, decisions can be made.  In short, if restoration is required far better it to be minimal intervention in the form of surface cleaning, canvas alignment and full checking of paint condition, stability and adhesion, than the problems of major paint loss and structural integrity caused by bad framing practice and general lack of care.   

Further thoughts concern the chosen conservator- restorer and their ability, knowledge, integrity, trustworthiness, skill, hand/ eye co- ordination, helpfulness, provision of reports and progress photographs.
