Whether plastic, wooden, or resin, making sure your garden shed remains in top condition is the key to avoiding unnecessary repairs and expenses. To minimize costly restorations, you won’t want to just look up the cheapest way to build a shed—you’ll do better to invest in a sturdy one and sustain it well. Take a look at our guide on regular maintenance in order to keep your shed in excellent shape throughout the year:

Check for leaks and breaks on the regular

Missing shingles or cracked windows can be a nightmare, especially during the rainy season. To prevent leaks, you’ll want to attend to breaks as soon as you spot them. Areas you should regularly inspect are: 

  • Windows 
  • Walls
  • Doors
  • Roofing
  • Floors and corners

Just as water can leak into your shed from up top, it can also leak in from below. As such, you’ll want to invest in a sturdy shed foundation. Three options that you can consider are: 

  • Cinder blocks
  • Concrete pads
  • Pressure-treated timber

Manage pests 

Wooden sheds, which are more susceptible to pests such as termites, require the proper pest-prevention system. You can easily keep your shed and the area around it pest-free by: 

  • Trim any vegetation in your garden routinely
  • Store firewood and garbage bins away from your shed
  • Ensure that any bags or jars containing seeds, soil, or fertilizer are completely sealed
  • Mop up any standing water to prevent rot and pest eggs 

On top of taking matters into your own hands, you can also schedule regular pest inspection to double down on keeping your shed pest-free.

Don’t forget door handles

Is your shed door too tight? Use a multipurpose lubricant such as WD-40 to keep your handles oiled and prevent issues such as rust or wood breakage from occurring. You’ll also want to replace a handle as soon as it stops working. 

Don’t neglect your shelving or your workbenches

If your shelves are sagging or your workbenches are leaning, don’t hesitate to replace them as soon as you can. You’re better off dealing with the wears and tears of your shed interior as they come rather than replacing your shed altogether. 

Take inventory of your tools and equipment

Take note of any tools or equipment you need to replace or repair by keeping an updated inventory. Popular items you’ll want to list are: 

  • Power tools
  • Toolbox staples
  • Lawn care equipment
  • Seasonal equipment

Give the floor a sweep

A quick, daily sweep inside your shed can keep pests away from the corners or cracks, and prevent certain areas from growing rot or mold. 

Enforce an organization system

A disorganized shed won’t only make finding certain tools or equipment a headache, you could be unknowingly providing pests with a place to hide or give mold a chance to grow. Consider incorporating any of the following to ensure that all your shed items are where they should be:

  • Pegboards: this storage option is incredibly versatile. You can use pegboards for shelving or hanging up heavier tools. 
  • Hooks: affordable and easy to install, hooks are perfect for hanging up items such as hoses or cords. 
  • Magnet strips: these are ideal for smaller, easy-to-lose items such as nails or screws. You can place them along the sides of your workbench or on walls. 

Prepare for the changing seasons

Make certain tools more accessible as the seasons change. During the winter, make sure you’re keeping shovels and scrapers in reach, whereas during the summer, you’ll want to prioritize items like hoses and garden tools. 

Power wash your shed’s exterior

At least once a year, you’ll want to give your shed a thorough scrub to remove any dust and grime. Remove stains along your siding to prevent mildew. For this, you may want to use a pressure washer to save on time and effort. 

Give your shed a new paint job

An excellent paint job doesn’t last forever. Every few years, treat your shed to a new paint job. Consider the following before you get started: 

  • What type of base you want for your paint
  • Whether to use a paint gun or brush
  • What type of paint thinner to use
