When it comes to small DIY projects or home repairs, we don’t often think about using packers and shims — but these simple little pieces can make many jobs easier and neater. Whether you’re levelling furniture, fitting a door, or fixing uneven shelves, packers and shims are handy tools to keep around the house.

Packers and shims are thin pieces of material used to fill gaps, level surfaces, or provide extra support. While steel packers and shims are common in big industrial projects, at home it’s much more practical to use rubber or plastic versions. These materials offer several benefits for household tasks.

Why choose rubber or plastic packers and shims?

Rubber and plastic packers and shims are slightly flexible, which means they can adjust to minor irregularities in surfaces. This flexibility helps give a snug fit where things don’t line up perfectly. They’re also corrosion-resistant, so you don’t have to worry about rust or damage over time, even in damp spots like bathrooms or utility rooms. Plus, they’re cheap and easy to find, making them a budget-friendly option for quick fixes.

Where can you use packers and shims at home?

Here are some of the most common uses:

Levelling furniture or appliances — Got a wobbly washing machine or a rocking table? Slip a packer or shim under the feet until it sits level.

Fitting doors and windows — When hanging a new door or installing a window, shims help ensure they’re square and level before you secure them.

Adjusting shelving units — If your shelves don’t sit flat because of an uneven floor, place small shims under the base to balance them out.

DIY builds — When assembling flat-pack furniture or making small woodworking projects, shims can help correct minor gaps or misalignments.

Tips for using packers and shims

Always check the thickness of the packers you’re using — many come in different sizes so you can stack them if needed.

Trim plastic or rubber shims with a sharp knife or scissors if you need to fit them into tight spaces.

If you’re using them in visible areas, choose clear or black versions so they blend in better.

Final thoughts

Packers and shims might be small, but they can make a big difference in the quality of your DIY jobs. By keeping a few rubber or plastic ones in your toolbox, you’ll be ready to handle those annoying little fixes around the home quickly and easily.
