Long-Term Storage Checklist
Complete preparation guide for storing items months or years
Preparing for Long-Term Storage
Long-term storage (6+ months) requires more preparation than short-term. Items sit longer, increasing risk of moisture damage, pest infestation, and deterioration. This checklist ensures your belongings stay protected whether you're storing for 6 months or 6 years.
⚠️ Long-Term Storage Rule
If it's not clean and completely dry, don't store it. Moisture is the #1 enemy of long-term storage. Even small amounts of dampness can lead to mold, mildew, and permanent damage over months.

Long-Term Storage Tips
Climate Control Considerations
Climate-controlled units maintain 55-85°F and reduce humidity. They cost 20-50% more but are essential for:
- Wood furniture (prevents warping, cracking)
- Electronics (prevents condensation damage)
- Documents and photos (prevents yellowing, mold)
- Leather items (prevents drying, cracking)
- Musical instruments (prevents warping)
- Anything stored 6+ months in humid climates
💡 Pro Tip: Moisture Absorbers
Even in climate-controlled units, place silica gel packets or moisture absorbers (DampRid) throughout your unit. Replace every 3 months during check-ins. This provides an extra layer of protection, especially in humid regions.
Pest Prevention
- Never store food - Even sealed items attract pests
- Clean everything - Crumbs and residue attract insects
- Use cedar or lavender - Natural pest deterrents
- Avoid cardboard long-term - Pests eat through it; use plastic bins
- Check during visits - Look for droppings or damage
Quarterly Check-In Routine
- Open unit and let air circulate for 10-15 minutes
- Check for signs of moisture, mold, or pests
- Inspect covers and wrappings for damage
- Replace moisture absorbers
- Verify nothing has shifted or fallen
- Update inventory if anything changed
When Long-Term Storage Doesn't Make Sense
Before committing to long-term storage, calculate whether it's worth it:
| Storage Duration | Typical Cost | Consider Instead |
|---|---|---|
| 1 year | $1,200-$3,600 | Keep if item value > $2,000 |
| 2 years | $2,400-$7,200 | Sell items worth less than storage cost |
| 3+ years | $3,600-$10,800+ | Only irreplaceable or very high-value items |
Frequently Asked Questions
How long can you store items in a storage unit?
There's no maximum time limit for storage units. Many people store items for years. However, you should visit your unit every few months to check on items, and consider whether long-term storage costs justify keeping items versus selling or donating them.
What should you not put in long-term storage?
Avoid storing perishable food, hazardous materials, flammables, plants, live animals, wet or damp items, and anything illegal. Also avoid irreplaceable items without proper insurance, and consider whether expensive climate-sensitive items are worth the risk.
How do you prepare furniture for long-term storage?
Clean thoroughly, disassemble if possible, wrap in moving blankets or furniture pads (not plastic), apply wood conditioner to wooden pieces, remove cushions from upholstery and store separately, and elevate furniture off the floor on pallets or boards.
