Maintaining a shipping container during the summer 

It is important to maintain your container on a semi-annual basis especially when it’s coming up to the summer or winter months where weather conditions can be harsh. Although containers are built to be extremely durable with stainless steel fittings and floors that have been treated to prevent rotting they can still be damaged when packed or transported.  If your shipping container has dents or cracks on it this can lead to corrosion and may make it unsuitable for use. It is important that you inspect and fix any repairs on your shipping container as early as possible.

Tips for maintenance portable storage during summer


General tips for shipping container maintenance during the summer mostly includes giving your container a thorough clean 

  • Give your shipping container a good pressure wash
  • Inspect the container semi-annually. If you live near the sea you may want to inspect it more often
  • Sweep the floor inside the container to check for signs of any damage or moisture

Keep it Level

Here are some tips for how to maintenance the shipping container in the summer. The placement of the container is very important and ensuring that it is on a flat surface will reduce the possibility of water gathering underneath the container.

  • Make sure the container is sitting level – if not, this can cause the container to “rack” or twist, and can make the doors harder to open and close
  • The container rests on the four corner castings (corner blocks).  If it becomes unlevel, you can jack up one corner and put more dunnage underneath
  • Make sure the container is sitting on solid ground. 


Once you have cut into your container to add windows and doors or modified them in various ways the structure of the container loses some of its durability. It is very important to check any modifications that have been done to your container. 

  • If you have made any modifications to your container make sure to check all modified areas especially around joins or areas that have metal on metal. Check all doors, windows and other openings. Look for any areas that may collect dirt or water and clean them. 
  • If you have a refrigeration unit in your container make sure that it has been recently serviced


Since shipping container doors are used frequently and are moving parts they are more likely to get damaged from wear and tear. Sea cans maintenance during the summer months should include a thorough inspection of all the doors and hinges.

  • Check all door seals to make sure they are intact.  You can also check this by having someone close the doors while you are inside, and checking for any light around the doors
  • Make sure that your rubber gasket seals on the door are still in good shape
  • Clean your doors by removing any dirt and rust from the hinges
  • Lube up the hinges!  Any spray lubricant will work for this.
  • Doors still stiff?  Heat up the hinges with a small torch to melt any build up in the hinges
  • Trim any grass or foliage around the container so that it doesn’t accidentally closed into the door seal


Checking the roof of your shipping container is the most important part of shipping container maintenance in hot climates. Regularly check the roof for dents that are known for collecting rainwater and causing corrosion.

  • Make sure that you don’t have too much weight on your shipping container roof. When shipping containers are stacked the weight is put onto the corner caskets and not the roof itself
  • Remove any dirt, debris, or water from the roof
  • Check for any holes/corrosion.  You can do this by climbing on top, or by simply going inside and having someone shut the doors, and looking for any light coming through at any spots of concern
  • Touch up any areas of corrosion that may be of concern with paint, or a roof sealant if you prefer
