Julia Nagle Conservation Ltd.

A highly-skilled and responsive team specialising in paintings from 1900, with an emphasis on minimal intervention and preventive care

Julia Nagle Conservation Ltd comprises a responsive team of experienced modern and contemporary painting conservators, a preventive conservator, and two registrars. Based in our own large, fully-equipped London Studio with excellent access, security, and Inward Processing Relief for imported artworks, we also travel to clients in the UK and abroad.

As specialists in paintings from 1900 to Contemporary, we are often the first conservators to interact with artworks and our emphasis is on minimal intervention, accurate documentation, and preventive care. With experience in museums and private practice, we bridge the gap between commercial and institutional conservation, providing holistic collection care and novel solutions to new problems. Our clients include artists, foundations, art advisors, commercial galleries, private and corporate collections, insurers, and public institutions in the UK and Internationally. 

Modern and Contemporary Art conservation

We conserve modern and contemporary artworks that have been damaged or neglected, which often include vulnerable, unvarnished paint surfaces requiring specialist knowledge. Working in clean, fully-equipped and secure modern premises with access for very large paintings, we liaise with living artists or their representatives as needed, and sensitively treat paintings that may never have been exposed to conservation before. Our experienced team, with strong links to conservation scientists and experts in other media, can respond to a wide range of novel conservation problems. We work on site if necessary, both in the UK and Internationally and are official conservators for Frieze and Frieze Masters Art Fairs. 

Condition Assessments and Collection Care

We provide holistic care for private and corporate collections in the UK and Worldwide, bridging the perceived gap between commercial and museum conservation. Collection condition surveys are undertaken and preventive and remedial conservation solutions recommended, prioritised and implemented. We provide advice on environmental monitoring, pest management, packing and transport, display, as well as professional documentation and oversight of loans in person or via virtual courier services.  

We provide independent condition assessments for insurers, loans, sales and purchase, for a wide range of clients based in the UK, USA, Europe, Africa, UEA, Australia and New Zealand.  

Artists, Artists’ Estates and Foundations

We are experienced in working with living artists to realise their artworks, and to ensure that subsequent treatments reflect the artist’s original intention. Through our relationships with artists and their estates and foundations, built over many years, we offer advice and practical support for commissions, varnishing and structural repairs, and ensure that treatments are ratified and retain the artist’s original intent. Where techniques are new or unorthodox, we are often able to obtain the necessary information and materials to achieve a successful repair. This in-depth knowledge also enables us to accurately assess the condition of a wide range of modern and contemporary artworks and advise on their future care.

Paintings post 1900

Many paintings from this period are by groups of artists that have hitherto been neglected, these include female artists and those from countries outside Europe or the USA. We employ a range of modern techniques to ensure that these paintings, many of which are unvarnished, are treated in a sensitive way with materials that will remain reversible, or allow for re treatment in the future. Tears are re woven under the microscope and protective insulated backboards that remain removable are applied to avoid the need for more invasive treatments such as re lining canvases, which set artworks off on a cycle of future restoration.
