How to Make Attic Storage Containers Airtight How to Make Attic Storage Containers Airtight

Putting items into attic storage containers is a good way of making sure they are preserved for a long time, without having to take them to a storage unit. On the downside, some attic storage containers can allow certain items, such as books, clothes, and shoes, to become damaged over time. Likewise, insects and even larger animals, such as mice, can force the lid open and damage your goods.

To prevent damage and decay, an attic storage container can be made completely air-tight, and anyone with only basic home-improvement tools can do it by following a few simple guidelines.

Step 1—Load Up the Containers

The first thing you will have to do is fill your containers. Try to place the items into the container as tightly as possible, so there is less movement within the container when you are taking it up to the attic. Also, make sure not to put items that are very heavy into a container, as you won't be able to carry it up and might even damage your attic joists.

Step 2—Insert Internal Lids

To make the inside of the containers as airtight as possible, you will need to place an internal lid over the mouth. These lids can be bought from cookery suppliers or craft stores and fit tightly around the mouth of the container, much like a rubber band.

You can also make your own internal lid by using some cling-film and a rubber band or a tie. Place the film over the opening in your container. Stretch it tightly so that there are no wrinkles and then attach it to the mouth using a rubber band.

Step 3—Apply External Lid

Once this small lid has been fitted, you can apply the external one. If the external lid has a depressor seal, it is the only one you will need. Press the lid down onto the mouth of the container and then force the handle down so that it forms a seal.

You may experience some resistance as you try and close the lid. Once you have the seal formed, wrap the outside of the container in duct tape, taking care to overlap the material as you go around the seal. Press it tightly into the side of the container.
