Make sure ALL of your items are clean and dry before storing them 

You’ve heard it said, “one bad apple spoils the whole bunch”? That is completely true and applies to mold and mildew issues within your storage unit. Be extra careful when placing items into storage on a wet and rainy day. One wet cardboard box, or a piece of furniture that is damp from the rain, can breed mold spores and ruin everything in your unit. 

Use the right type of storage container or box 

Choose your box or container carefully. Consider the item placed in the box. Does it need to be able to ‘breathe’ or should it be kept airtight? Clothing often works better in plastic, airtight containers to keep out moisture and unwanted dust, bugs, etc. But other items may better benefit from cardboard boxes that allow the items to breathe. 

Consider a vapor barrier 

Our storage units have concrete floors. Concrete will naturally draw moisture from the earth overtime. This is usually only an issue when the grounds have been heavily saturated by prolonged seasons of heavy rains. Placing a tarp or plastic on the floor of unit, under your items can prevent the moisture from being drawn up into your cardboard boxes and furniture pieces. 

Use a moisture-absorbing product 

Products such as DampRid can be placed in the unit to absorb the moisture within the space. Just keep an eye on the product to make sure to replace them per the product instructions. 

Be mindful of airflow within the unit 

Try to avoid stacking the unit so full that air cannot flow through the unit. Though it is tempting to rent the smallest unit possible and fill it completely full, this may not be the best approach. Pallets placed underneath boxes and furniture is another easy way to create airflow around your items. 

Choose a Climate-Controlled unit 

The air flow that is forced through our climate-controlled buildings is designed to help discourage the growth of mold and mildew. While the above measures are still encouraged, even in a climate-controlled building, having this airflow does put you on the right path for preventing mold and mildew. 

Check on your unit frequently 

The items in your unit should be checked at least monthly. The Property Manager is not able to see inside your unit to know if there is a problem. We urge you to be proactive and alert us immediately if you feel there is an issue.
