Furniture damage in storage is mostly preventable. Here is how to prepare wood, upholstery, marble and electronics so they come out as good as they went in.
Most storage-damage we see at the retrieval end is preventable. Customers store furniture without proper preparation, leave it for months or years, and discover at the retrieval that the wood has warped, the upholstery is musty, or the marble has cracked. With a few hours of preparation before storage, almost all of this is avoidable. After forty years of Sussex moves and tens of thousands of cubic metres stored at our Lower Dicker depot, we have a clear method.
This guide covers the preparation by material type (wood, upholstery, leather, marble, electronics, mattresses), the climate considerations, and the long-term storage gotchas. For the wider storage-format decision (drive-up vs strong-room, short-term vs long-term), our choosing-storage guide covers the format choice. For the contractual side, see the short-vs-long-term guide.
Wood breathes. The moisture content of wood furniture adjusts to the relative humidity of its environment. Move it from a heated, humid home (typical UK winter interior is 40–55% RH) to a cold, dry storage unit (an uninsulated steel container in February might be 65–80% RH on damp days and 20–30% on cold dry ones) and the wood will work over weeks. Joints loosen, veneer lifts, panels warp.
The fix starts with climate-stable storage. Climate-stable means insulated walls, controlled ventilation, no direct sun. Our strong-room storage at the Lower Dicker depot is climate-stable by design; standard uninsulated self-storage often isn’t. The choosing-storage guide covers the format differences.
Beyond the environment, the preparation: clean the wood before storage (dust and dirt trapped against finishes will damage them over time), treat any minor scratches with appropriate wood polish or wax, tighten any loose joints before storage rather than after, and wrap in breathable cotton sheets rather than plastic. Plastic traps moisture; cotton lets the wood breathe normally.
Upholstery is the highest-risk furniture category in long-term storage. Fabric absorbs ambient moisture, and any moisture trapped in foam padding can lead to mould growth over months. The damage is typically irreversible — mouldy sofas are usually a write-off.
Preparation: deep clean the upholstery before storage (vacuum, then steam-clean if heavily soiled; let it dry fully before wrapping), avoid plastic wrapping entirely (traps moisture, the single worst thing for upholstery), use a breathable cover such as a cotton sheet or specialist furniture cover, and store off the floor on a small wooden pallet to prevent moisture wicking up from concrete floors.
For genuinely valuable upholstery (antique sofas, designer pieces, vintage chairs), climate-stable storage is non-negotiable and a higher-tier facility like our Prestige Steel Storage rooms is appropriate. The cost differential is meaningful but the alternative (mouldy upholstery write-offs) is worse.
Mattresses follow upholstery rules but with extra emphasis on the mould risk. A mattress stored in a damp environment can become unusable within weeks. The standard preparation: vacuum thoroughly, let air for 48 hours before bagging, use a breathable mattress bag (not the plastic shrink-wrap that some self-storage providers supply), and store flat or upright (never folded — modern foam mattresses develop permanent compression marks if folded).
For pillows, duvets and bedding: bagged in cotton or breathable polypropylene bags. Vacuum-pack bags work for storage but the items need airing for 24 hours before use again. Don’t store damp bedding; it will mould.
For bed frames, the preparation depends on the material. Wooden frames follow the wood-furniture rules above. Metal frames are robust but the connection joints can corrode over time in damp storage; light oiling of bolt threads before storage prevents this. Mention bed frames specifically at survey if you’re storing them — we’ll cover the disassembly and reassembly.
Leather furniture needs particular care in storage. Cold dries leather and causes cracking; humidity causes mould on leather like on fabric. The preparation: clean and condition the leather before storage with proper leather conditioner, store in climate-stable conditions (uninsulated storage is genuinely damaging for leather over months), wrap in cotton or specialist leather covers (never plastic), and reapply conditioner every 6–12 months if the storage period is long.
Marble and stone furniture has a different set of issues. Marble is porous; it absorbs moisture and stains. Marble-topped tables need particular attention: clean the top with appropriate marble cleaner (no acidic household cleaners), seal the surface with appropriate marble sealer if it hasn’t been done recently, and store the top vertically (never flat for long-term storage; the slow flex causes cracking).
For very high-value materials (museum-grade antiques, fine art, rare collectibles), specialist climate-controlled storage with humidity regulation is the right answer. Standard climate-stable storage handles most domestic high-value items; very high-end material warrants specialist storage. Talk to us at survey if your storage involves genuinely irreplaceable items.
Electronics have a different storage risk profile from furniture. The main risks: temperature extremes (very hot or very cold storage can damage electronics, particularly lithium-ion batteries), humidity (can cause corrosion on internal components), and physical damage from poorly-stacked stored items.
Preparation: remove lithium-ion batteries from devices that allow it (laptops, power tools, e-bikes — the batteries degrade in storage and may not work after long periods), store in original boxes where possible (the original packaging is sized for the device and provides appropriate protection), label clearly with the device name and any specific re-setup needs.
For valuable electronics (camera collections, hi-fi systems, recording equipment), specialist humidity-controlled storage extends the safe storage period significantly. Standard climate-stable storage handles routine household electronics for months at a time without issues. For storage over a year, specialist climate-controlled is worth considering. The fragile-items guide covers the pre-storage packing methods.
For genuinely long-term storage (over a year), schedule periodic checks. The standard pattern: a check at 3 months, then 6 months, then 12 months. Each check involves a brief visit to the unit, a visual inspection of the contents, and any minor maintenance (re-conditioning leather, re-tightening wood joints, checking electronics).
For customers using strong-room storage where direct access requires arrangement, the checks happen by request. We offer a quarterly inspection service for our long-term storage customers — our staff opens the room with the customer’s permission, checks for any concerns, and reports back. The cost is modest relative to the value of what’s stored.
For genuinely irreplaceable items, the check schedule matters more than for routine storage. The Prestige Steel Storage rooms are designed with this longer-term holding in mind. The format choice is in the choosing-storage guide; this guide is the preparation side.
We've been a family-run Sussex remover since 1982 — the same name on the lorry as the name on the paperwork. Mark personally surveys the high-value and overseas moves; our crews are directly employed (not casual day labour) and trained at our own staff training centre, one of only a handful of UK removers with that facility on site.
Standard inclusions on every full removal: pad-wrap protection for every freestanding piece of furniture, removal-grade cartons, a written and itemised fixed-price quote with no surprises on the day, and the British Association of Removers' Advance Payment Guarantee protecting every deposit. The result, over forty years and tens of thousands of moves, is a 4.9/5 review average across 120+ independent Google reviews.
Booking the survey takes ten minutes. Whether it's a one-bedroom flat across Eastbourne or a country house to overseas, the process is the same: in-home or video survey, written quote within 48 hours, deposit-protected booking, and a calm move day.
Free in-home or video survey, written fixed-price quote, BAR-protected deposit. Sussex’s family-run remover since 1982.
One last operational note: for storage holds of more than 6 months, we offer a periodic-check service for our long-term storage customers. Our staff opens the room with the customer’s permission, visually inspects the contents, and reports back. The cost is modest relative to the value of what’s stored and the early-warning detection of any environmental issue is genuinely valuable. Mention this at survey if your storage timeline is genuinely long.
For your specific move, the free survey takes ten minutes and we’ll come back within 48 hours with a fixed-price quote and clear plan. Forty years of Sussex moves behind every survey.
For stays over 2-3 months, yes. Uninsulated steel-walled storage units in British winters cause condensation that warps wood and lifts veneer. Climate-stable storage is non-negotiable for furniture you care about.
No — plastic traps moisture and causes mould on upholstery and mildew on wood finishes. Use breathable cotton sheets or specialist furniture covers instead.
Folding them — modern foam mattresses develop permanent compression marks. Store flat or upright, never folded. And always in a breathable mattress bag, not plastic shrink-wrap.
For long-term storage (over 3 months), yes. Lithium-ion batteries degrade in storage and may not work after long periods. Store batteries separately in a cool, dry place.
Every 3 months ideally for the first year. For our Prestige Steel Storage customers we offer a quarterly inspection service. Visit reports are standard for long-term contracts.
