Purchasing a portable shipping container is a cost-effective way of creating more space without having to invest in building a new structure. Shipping containers can be used for storage, customized into an office space or workshop area, used for growing food or specialty plants, and even make great emergency assistance housing. 

However, it is very important that once you have purchased a shipping container that you keep up with the maintenance on it to ensure many years of use. 

Maintenance Tips For Shipping Containers 
The Roof 

You should make sure that the roof of your container is kept clean of debris and that you do not allow water to pool on it for extended periods. Although these containers are designed to withstand harsh weather conditions, allowing debris, water, or ice to remain on the roof can lead to rusting if there are any knicks or scratches in the paint. 

Although these containers are designed to be stacked on top of each other, it is important to realize that the corner areas are reinforced for this type of weight, not the entire roof. If you are going to store stuff on top of your container, make sure it is light enough not to cause the roof to bow. 

Windows and Doors 

It is recommended that you replace any loose caulking around the windows and doors and the weather stripping to keep your container airtight. This helps keep the weather out and your property protected.  

You are also encouraged to oil the hinges on the windows and doors once per year. This keeps them moving freely and easy to use. Time and weather conditions can lead to rust in these areas, and the oil coating will help prevent rust damage.

Plumbing, Electrical and Heating, and Cooling 

At least once a year, you should complete a routine check on all of your plumbing, electrical, and heating and cooling equipment installed in the container. Clean hoses, replace items that look worn, and replace filtration systems. If you use any of these, it’s a lot, such as plumbing for growing, you may want to complete this maintenance twice per year. 


Always check the foundation for your container at least once per year. Settling will occur, even with a cement foundation, and this could cause your container to be tilted. Leveling your container will help keep the container from experiencing tension in areas that could lead to a loss of structural integrity. 

Cleaning the Outside 

It is also important to keep the outside of your container clean. Use a mild detergent and a hose to clean off the outside of the container. This will eliminate mildew build up in areas that are humid and keep debris from affecting the paint. Check the paint for knicks or chips and touch them up accordingly. This will help prevent the container from rusting. 

These simple maintenance tips will ensure that you get extended use from your shipping container.
