Storage for Private Collections: What to Ask a Facility

Why storage becomes necessary

Collections accumulate faster than wall space, houses get renovated, works rotate, and some pieces are simply not suited to permanent display. Storage is normal and not a failure of planning.

It is, however, where a collection is least observed. A work on a wall is seen daily and any change is noticed. A work in a rack is not, and slow deterioration in poor conditions can progress for years before anyone opens the crate.

Environment: ask for the data

Every facility will say it is climate controlled. The meaningful question is what the environment actually does, not what the system is specified to deliver.

Ask for logged temperature and relative humidity data for the specific area your works would occupy, over a full year. Stability matters more than any particular target: repeated swings cause more damage than a steady value slightly away from ideal, because materials expand and contract at different rates.

Ask what happens during a power failure, whether there is backup, and how quickly conditions recover. Ask about light exposure in the storage area and during any viewing.

Insurance: whose, and how much

Facilities carry their own insurance, and it is frequently capped at a level appropriate for general goods rather than for a collection. Ask what the limit is, what it covers, and whether it is per-item or per-client aggregate.

In most cases the collector's own fine-art policy should extend to cover works in storage, at the stored location, at agreed values. Confirm this explicitly with your insurer, because some policies restrict cover away from the scheduled premises.

Where the facility limits liability contractually — and most do — read that clause before signing rather than after a loss.

How the works are actually stored

Paintings should be racked vertically on padded screens or stored in crates, never stacked face to face without separation. Works on paper belong flat in archival boxes or solander cases, in acid-free materials. Sculpture needs stable mounting appropriate to its centre of gravity.

Ask to see the storage area. A facility confident in its operation will show you; reluctance is informative. Look at whether works are off the floor, whether aisles are clear, and whether the space is being used as a working area.

Do not leave it unattended

A stored collection needs a schedule: periodic inspection, condition checks on anything fragile, and an inventory reconciliation against the records.

Annual is a reasonable default for a stable collection, more often for works with known vulnerabilities. The point is that someone looks — because the alternative is discovering a problem when the work is next needed, by which time the cause is years old and the cure is expensive.
