Preparing Your Unit for Long-Term Storage: What to Know

If you plan to store your belongings for several months—or even years—taking the time to prepare them properly will save you stress later. Whether you’re relocating, downsizing, or decluttering, preparing your unit for long-term storage the right way helps protect everything you value.

At All American Self Storage San Mateo, we’ve seen how careful preparation keeps furniture, electronics, and family keepsakes in great condition. Here’s your step-by-step guide to long-term storage success.

1. Clean and Dry Before Preparing Your Unit for Long-Term Storage

The first step in preparing your unit for long-term storage is to clean and dry every item. Even small amounts of dust or moisture can lead to mold, mildew, or pests.

• Furniture: Wipe down with mild soap and water, and let it air-dry.

• Appliances: Defrost and clean refrigerators or freezers; leave doors slightly open.

• Clothing: Wash and dry completely before packing.

San Mateo’s coastal air can get humid, so dry items are your best defense against damage.

2. Choose the Right Packing Materials for Long-Term Storage

The packing materials you use play a huge role in how well your items hold up over time. When preparing your unit for long-term storage, invest in high-quality supplies.

• Use sturdy plastic bins with lids for clothing and small electronics.

• Wrap furniture in breathable covers or moving blankets, not plastic.

• Label every box with its contents and the room it came from.

At All American Self Storage San Mateo, our clean, updated units provide the ideal environment—but strong packing materials add an extra layer of protection.

3. Disassemble Furniture Before Long-Term Storage

Large furniture takes up valuable space and can warp if stored improperly. Disassembling it is an important part of preparing your unit for long-term storage.

Remove legs, shelves, or table tops and wrap each piece separately. Keep screws, bolts, and small hardware in labeled bags taped to the furniture.

When you’re ready to unpack, you’ll have everything neatly organized and ready to reassemble.

4. Organize Your Space When Preparing Your Unit for Long-Term Storage

An organized unit makes it easier to find items later and prevents damage. Create a layout before stacking boxes.

• Place heavier boxes and furniture on the bottom.

• Store fragile or light boxes on top.

• Leave a walkway down the middle for easy access.

This approach keeps your long-term storage tidy and safe, especially if you plan to check in periodically.

5. Protect Against Moisture in Long-Term Storage

Moisture is one of the biggest threats during long-term storage. When preparing your unit for long-term storage, take precautions to prevent it.

• Use moisture absorbers or silica gel packs inside boxes.

• Keep items off the floor by placing them on wooden pallets or plastic shelving.

• Avoid sealing boxes with plastic wrap, which can trap humidity.

These small steps go a long way in keeping your belongings fresh and mold-free.

6. Check In Regularly on Your Long-Term Storage Unit

Even with great preparation, it’s wise to check in every few months. Make sure nothing has shifted and that moisture levels are under control.

At All American Self Storage San Mateo, our individually-alarmed units, gated access, and extended hours (7:00 a.m.–8:45 p.m.) make checking in convenient. We keep your belongings safe so you can focus on what’s next.
