Top 7 Mistakes to Avoid When Using Storage Units

by / ⠀Blog / July 14, 2025

In today’s fast-paced world, storage units have become a lifesaver for many people. Whether you’re moving, downsizing, or just trying to organize your life, self-storage units offer a convenient solution for your extra belongings. However, while they provide valuable space, using them effectively requires some thought and planning. Unfortunately, many individuals make simple but costly mistakes when renting storage units. These mistakes can lead to unnecessary frustration, damage to items, or even wasted money. In this article, we’ll explore the top seven mistakes to avoid when using storage units to ensure your experience is smooth, efficient, and cost-effective.

1. Choosing the Wrong Size Storage Unit

One of the most common mistakes people make is selecting the wrong size for their storage unit. It’s easy to assume that a smaller unit will be enough, but often, it ends up being too cramped. On the other hand, choosing a unit that’s too large can result in paying for unused space. Both situations are avoidable with a bit of planning.

To avoid this mistake, take time to assess what you plan to store. It’s helpful to measure large items like furniture and appliances. If you’re unsure, most storage facilities offer helpful size guides or staff who can assist with recommendations. Typically, a 5×5 unit is suitable for boxes and small furniture, while a 10×10 or larger unit is better for a whole household’s worth of goods.

Understanding your specific needs can prevent you from wasting space or money on a unit that’s not right for you.

2. Not Packing Items Properly

Another mistake that can have a significant impact on your storage experience is not packing your items correctly. The way you pack your belongings can affect both their safety and your ability to maximize the space in your unit.

Start by using sturdy boxes that won’t collapse under weight. For fragile items, like glassware or electronics, be sure to pack them with plenty of padding—bubble wrap, packing peanuts, or even old clothes can do the job. Additionally, always label your boxes clearly with their contents and room of origin, so you won’t have to guess when you need to retrieve something in the future.

It’s also important to think about the layout of your storage unit. Store heavier items at the bottom and lighter, more fragile items on top. Leave aisles between stacks for easy access. Packing efficiently not only protects your belongings but also makes it easier to find what you need when you visit your unit.

3. Failing to Consider Climate Control Needs

Many people overlook the importance of climate-controlled storage, especially if they’re storing items like electronics, artwork, or sensitive documents. Standard storage units may not protect from extreme temperatures or humidity levels, which can lead to damage over time.

For example, wooden furniture, antiques, or photographs can warp or deteriorate in high humidity. Similarly, electronics like computers, televisions, and appliances can suffer internal damage if exposed to fluctuating temperatures.

If you plan to store items that could be harmed by weather conditions, investing in a climate-controlled unit is worth it. Secure self-storage facilities near Bainbridge, for instance, may offer climate-controlled options that ensure your belongings stay in optimal condition year-round.

4. Storing Items Without Insurance

While many storage facilities offer security features such as surveillance cameras and gated access, the fact remains that accidents or unforeseen events, such as floods or fires, can happen. That’s why it’s essential to have insurance on your items while they’re in storage.

Storage unit insurance is often available through the facility itself or a third-party provider. While it’s tempting to forgo insurance to save a few extra dollars, it’s a gamble that could cost you more in the long run if something goes wrong.

Before renting a unit, ask about insurance options and read the terms carefully. The right coverage will provide peace of mind, knowing that your valuable belongings are protected, even in the worst-case scenario.

5. Not Labeling Boxes or Making an Inventory

One of the biggest headaches when storing items is not having an organized system in place. Imagine trying to find a specific item after months of storage, only to realize you have no idea which box it’s in. Without proper labeling or an inventory, this scenario can quickly become a nightmare.

Be sure to label every box clearly, detailing its contents. This simple step can save you significant time and effort when you need to access something in the future. You can also create a detailed inventory list, which helps track what’s in each box and where it’s located in the unit. Keep the list handy or store it digitally for easy reference.

Having an organized system is not only helpful for finding items but also for ensuring you don’t forget anything when you move out or return items to storage.

6. Failing to Secure Your Storage Unit Properly

Storage unit security should always be a top priority. Many people make the mistake of thinking their items are completely safe just because the facility has gates and surveillance cameras. While these features are important, they’re only effective if you take steps to secure your own unit properly.

Always invest in a high-quality lock. Disc locks are often recommended because they are more secure than standard padlocks. Additionally, when you visit the facility, take a moment to check for any signs of tampering or damage. Look for a well-maintained facility with strong security features, such as 24/7 surveillance cameras and well-lit areas.

Taking responsibility for the security of your belongings is an essential step in ensuring their safety. After all, no amount of facility security can replace the effectiveness of a good lock.

7. Ignoring Facility Access Hours and Restrictions

Many storage units have specific hours during which you can access your belongings. Not being aware of these access hours can result in unnecessary frustration, especially if you need something urgently outside of regular hours. Make sure you are fully aware of when you can access your unit, and check if the facility offers extended hours or 24/7 access for added convenience.

It’s also important to familiarize yourself with any restrictions the facility may have regarding the types of items you can store. Some facilities may prohibit hazardous materials like chemicals, paint, or flammable items. Before moving in, take note of these rules to avoid confusion or problems later.

Choosing a storage facility with flexible access hours and clear policies can make your experience much more convenient and hassle-free.

Conclusion

Using a storage unit can provide the extra space you need to declutter and organize your life. However, as we’ve seen, several common mistakes can lead to frustration, financial loss, or even damage to your belongings. By choosing the right size unit, packing properly, considering climate control, ensuring proper insurance, labeling boxes, securing your unit, and understanding access rules, you can make the most of your storage experience.

Take these tips into consideration before renting a storage unit, and you’ll ensure that your belongings stay safe, organized, and easily accessible. Avoiding these mistakes will save you time, money, and effort in the long run.
