Conservation Cleaning Projects

O’Sullivan Conservation recognises the integral role that meticulous cleaning and preservation play in safeguarding cultural heritage objects and building interiors. Our team of experienced professionals provide on-site cleaning and conservation housekeeping services for historic buildings, museums, and decorative interiors. We collaborate closely with curators, conservation departments, and facility managers to ensure the utmost care for collections and architectural interiors.

While many museums and historic properties maintain in-house preventive conservation, there are instances where specialised expertise or additional support is required. Our services cover conservation cleaning for historic buildings and museum storage, after-hours cleaning of museum displays, at-height cleaning, top-down cleaning, pre- and post-works cleaning, and the meticulous preparation of collections for display.

O’Sullivan Conservation is a trusted partner for several heritage organisations and museums, assisting with a range of individual projects, and ensuring that each project receives the conservation care it deserves.
