Conservation Guidance Targets Humidity, Light and Handling as Main Threats to Stored Art

other · 2026-10-19

Artworks frequently sustain damage during crating, moving, or when housed in inappropriate environments. The primary threats include humidity fluctuations that lead to cracked paint and warped panels; exposure to light, which can diminish the quality of paper and textile pieces; pests and dust, especially in basements and garages; and physical handling, where most damages occur. To mitigate these risks, it is advised to keep humidity levels between 45-55%, store items in darkness, utilize custom crates, maintain climate control throughout the year, and follow a documented retrieval process. In hurricane-prone areas, proper construction is essential; William C. Huff, established in 1908, creates fine art storage solutions that can endure Category 5 winds, offering detailed inventories and condition reports for every item.

Key facts

  • Storage damage typically begins after works come off the wall, during crating and relocation
  • ICOM-CC and IIC guidance recommends roughly 45 to 55 percent relative humidity at 65 to 75 degrees Fahrenheit, with stability the priority
  • Light exposure causes irreversible fading in works on paper, textiles and many pigments
  • Cardboard boxes attract pests and should never be stored with art
  • Most storage losses are attributed to handling rather than environmental conditions
  • A dated condition report with photographs supports insurance claims, appraisals and resale
  • William C. Huff was founded in 1908
  • William C. Huff's newest fine art storage space is built to withstand Category 5 winds over 177 mph
