Should You Choose Climate-Controlled or Drive-Up Storage?

Storage unit size is only one part of the decision. You should also consider what type of storage environment makes the most sense for your belongings.

Climate-Controlled Storage

Climate-controlled storage is especially useful in South Florida, where high temperatures and humidity can affect certain materials over time.Consider climate-controlled storage for items such as:
  • Wooden furniture
  • Electronics
  • Photographs
  • Documents
  • Artwork
  • Books
  • Clothing
  • Collectibles
  • Musical instruments
  • Other temperature- or humidity-sensitive belongings
Florida Secure Self Storage offers climate-controlled unit options including 5x5, 5x10, 10x15, and 10x20 sizes.

  • Furniture

  • Business inventory
  • Tools
  • Contractor equipment
  • Household moves
  • Frequent access

How Do I Know What Size Storage Unit I Need?

Start by making a list of everything you plan to store.Pay particular attention to your largest items, including:
  • Sofas
  • Beds
  • Dining tables
  • Appliances
  • Dressers
  • Shelving
  • Patio furniture
Next, estimate how many moving boxes you will have.If possible, disassemble large furniture such as bed frames, tables, and shelving. This can dramatically reduce the amount of floor space required.You should also consider whether you will need regular access to your belongings. If so, choosing a slightly larger unit may allow you to create a walkway through the center instead of packing everything tightly from wall to wall.

Should I Rent a Storage Unit That Is Slightly Larger Than I Need?

Sometimes.Choosing the smallest possible storage unit may save money, but it can make accessing your belongings more difficult.A slightly larger storage unit can provide room to:
  • Create walkways
  • Organize boxes by category
  • Access frequently used items
  • Add shelving
  • Avoid stacking fragile belongings too high
  • Add additional items later
If you expect your storage needs to change, having a little extra space can be worthwhile.

How to Maximize Space in Your Storage Unit

No matter which size you choose, packing efficiently can help you get more value from your storage unit.

Use matching box sizes

Uniform boxes are easier and safer to stack.

Disassemble furniture

Remove table legs, bed frames, shelving, and other detachable pieces whenever possible.

Store vertically

Use the full height of the storage unit rather than only filling the floor.

Place heavy boxes on the bottom

Keep heavier and sturdier items underneath lighter or fragile belongings.

Leave a walkway

If you will access your unit regularly, leave a narrow path through the middle.

Keep frequently used items near the front

Holiday decorations, business inventory, sporting equipment, and other items you may need periodically should remain easy to reach.
