Protecting your storage from condensation

Humidity can be a big problem wherever you look. Whether it is in your house or your storage unit. Humidity can affect your health as well as the state of your items. The humidity levels should range from 30% to 50% and protecting your storage from condensation should be a big concern to you. Anything above that can be detrimental both to your and your item’s health. If humidity starts building up in your storage unit everything that you have placed inside will become prone to developing mold, mildew, corrosion, and rust. So if you have anything valuable placed in your storage unit, this needs to be checked as soon as possible. All those things you have stored need to be well protected against humidity in order for it to stay in good condition.

So, protecting your storage from condensation is a must and should not be taken lightly. Let’s see what steps can you take to prevent the condensation level from building up.

Check the humidity level

In order to stay safe from condensation, you need to check humidity. There are two ways you can approach this. Either call up a professional to check the humidity level, or buy a humidity gauge. Even though the gauge is not 100% accurate, it can give you an idea on what the humidity level is. Both of these options will cost a bit (the gauge is going to be cheaper in the long run) so make sure you revise your budget and make sure you can take this step financially. Preparing a relocation budget can be hard, so do your research on that!

After checking the humidity level, you need to find the source. You should do a full visual inspection of our storage unit and see if anything in the unit has developed mold. If you find something with mold on it do not hesitate to call a professional to get everything sorted out. If there is not any mold on your items, and your humidity level is high, you should take precautionary steps to prevent it.

Checking if your storage unit has any leaks

This is mostly relevant if you want to rent an outdoor storage unit. Outdoor storage units are more prone to leaks and cracks because they are exposed to the elements more. Storage Baltimore can, with certainty, offer you well-built storage units without any cracks or leaks. In the unfortunate event of that happening, you should try to seal them off. Contact the storage facility owner in order to address this problem directly. Even if the unit does not have cracks or leaks, it is good practice to check it every now and then. Natural elements are known for disrupting our endeavors, and this is another case of that

Prepare your items for storage beforehand

You need to check if all of your items are dry before storing them. Protecting your storage from condensation should be one of your main concerns and you should not take this matter lightly. Every single item in your storage unit should be 100% dry. If you have dried everything except one item, that is the same as not drying anything. Condensation from one item can affect the humidity level in your storage unit and thus affect all of your stored belongings. This also applies to protecting your furniture while moving, make sure to think about that.

Vapor barrier technology

This is a great way of protecting your storage from condensation. A vapor barrier is a polyethylene or plastic foil that you can get at any local hardware store. You should put it inside your storage as a means of preventing the humidity from outside to seep into your unit. Install it both on the floor and on the walls. Even on the ceiling. You can never be too careful when protecting your storage from condensation.

Using desiccants

A desiccant is a material that absorbs moisture. Do you remember that tiny pack in your brand new shoe box that contains small marbles? This is called silica gel, and it is one of the materials that can absorb moisture. You can purchase silica gel or other types of desiccants in your local hardware store. Even local movers Baltimore use desiccants when moving during humid weather. Professionals know what they are doing, and you should follow in their footsteps.

Desiccants are a good option of keeping the humidity levels low

If you do not want to buy a desiccant, you can also try to make some of your own. You can do this by getting a piece of fabric and some silica gel. Cut the fabric into two small rectangular pieces. After that, put some silica gel between them and sew them together. Put your creation inside your storage unit and enjoy the fruits of your labor. Furthermore, do not forget to regenerate your desiccant. Silica gel can absorb up to 40% of its weight. This does not mean that you need to buy a new batch of silica gel. Just put it on a heating unit so the moisture leaves the gel. A very easy way to renew your desiccants.

A natural way of keeping moisture off your belongings

This should not come as a surprise in this day and age. People are turning to natural solutions for almost any problem, and why should this be any different. A great natural desiccant is a charcoal. In addition to its absorbing moisture, it will also absorb foul odors. A two in one package! In order to use them, make the same small package as you would with the silica gel. Afterwards, put it in your storage unit, and watch the humidity levels go down. However, this way of absorbing moisture is not renewal, so you need to replace the charcoal every month or two. We all know what would happen if you put charcoal in the oven, so do not make the mistake of trying just that!


When protecting storage from condensation, there are so many options that, with proper effort, will make the job seem like a breeze. To sum it up, find a storage unit without any leaks. If you cannot, then use silica gel or charcoal as a desiccant. Also, do not forget to dry all of your belonging before putting them in storage.
