Plastic sheds have remarkable features that make them stand out from their counterparts. The material used continues to improve over time, and it may get even better than wood and metal in some aspects.

But we understand that you may still have questions about these outdoor structures. You want your investment to be worthwhile, and we’re here to give you that assurance.

Here, we’ve compiled a list of plastic shed FAQs covering all the basics you need to know before making a purchase.

What’s the difference between vinyl and polycarbonate plastic sheds?

By definition, you might assume that plastics are weak materials. The truth is quite the opposite: they’re surprisingly strong and versatile. Two popular types of plastics used in shed construction are vinyl and polycarbonate.

A vinyl shed comprises PVC (polyvinyl chloride) panels reinforced with metal. It’s durable and resistant to weather but can crack or fade over time if overlooked. Vinyl sheds also have a more traditional appearance, resembling wooden structures.

In contrast, polycarbonate sheds are made from a more advanced form of plastic. They’re virtually unbreakable and resist fading, cracking, and discolouration. Plus, polycarbonate is lighter and easier to assemble than its vinyl alternative.

Are plastic sheds better than wood?

The plastic used may not be the most resilient, but it has properties that wood lacks. For starters, it’s not susceptible to rot and can last longer in wet conditions. Plastic sheds are generally more affordable and easier to maintain. They’re lightweight, and assembly is a lot easier compared to wooden sheds.

It’s important to note, though, that timber sheds typically offer better insulation. Plastic sheds can also be vulnerable to wind if not securely anchored.

How long do plastic sheds last?

Generally, plastic sheds can last anywhere from 10 to 20 years with care and maintenance. This can vary depending on the material, the weather conditions, and how well it is maintained. For instance, if the shed is exposed to extreme heat, cold, or heavy rain, it may deteriorate more quickly.

Regular cleaning, checking, and repairing any issues can help extend its lifespan. The manufacturer’s warranty may also indicate longevity.

Do you need to insulate plastic garden sheds?

Whether you need to insulate it depends on its use and your location — but it’s not generally necessary. If the purpose is solely for use as storage, such as keeping your garden tools, insulation may not be worth it.

If you opted for a wood floor installed instead of the same material, have it pressure-treated. Disregard if your plastic shed comes with a foundation kit.

Do plastic sheds need a base?

No foundation under your shed, regardless of the material, is risky. While you can get away with not putting yours on a level foundation, we strongly advise against it. A well-built foundation is essential for the stability and longevity of your shed.

When constructing the plastic shed base, follow the manufacturer’s instructions and guidelines. This helps ensure the shed unit is properly supported and protected.

What are the base types ideal for a plastic outdoor shed?

Regardless of the shed type you choose, you’ll want to ensure it’s built on a level and stable surface. Otherwise, everything will be wonky! Your options include plastic base kits, paving slabs, and a concrete base.

Plastic shed base kits require no drilling or screwing things together. They’re free-draining and self-ventilating, so they do a great job keeping your shed floor dry.

Paving slabs are the old-school version of modern plastic grids. They provide a more solid base and better security than plastic. Concrete bases provide the strongest and most durable foundations. Yet, they’re also the most expensive and labour-intensive to install.

When choosing a base, consider the shed’s weight and size, as well as the weather conditions in the area. Proper base installation is also crucial for longevity and functionality.


How do you anchor a plastic shed without concrete?

This can be done in several ways, and one method is to use ground anchors. Screw them into the ground and attach to the shed using cables or straps.

Another option is to use heavy-duty stakes with metal floor brackets. Some plastic sheds also come with built-in anchor points. These can be used to secure the shed using stakes or anchors. Regularly inspect and maintain these anchors to keep the shed secure and stable.

Do plastic sheds get condensation?

A plastic shed will only suffer from condensation when dampness is present in the foundation. The air inside the shed is always slightly warmer than outside. Thus, any moisture in the foundation base will rise until it touches the cold roof panels. This can cause mould, which can damage your belongings stored inside.

Proper ventilation is essential to prevent such issues. This can be achieved by simply opening the windows or installing vents.

Are plastic sheds easy to put up?

Are plastic sheds resistant to pests and insects?

Plastic sheds are generally more resistant to pests and insects than wood sheds. This is because plastic materials provide less favourable conditions for pests to infest. This reduces the risk of damage from termites, rodents, or other insects.

Can a plastic shed withstand extreme weather conditions?

Plastic sheds are designed to withstand harsh weather conditions and are UV-resistant. This means they won’t fade or crack under prolonged sun exposure.

However, extremely strong winds or heavy snow loads may require additional reinforcement. This includes proper anchoring to ensure stability and prevent damage.

Consider the weight and size of the items you intend to store. Also, ensure the plastic shed’s specifications meet your requirements.

Can I disassemble and relocate a plastic shed?

Yes, one of the advantages of plastic sheds is their ease of disassembly and relocation. They’re lightweight, making it possible to dismantle and move them around. Follow the manufacturer’s instructions for proper disassembly and reassembly.

Are plastic sheds fire-resistant?

Plastic sheds aren’t fire-resistant, but they have low ignition points. This means they can melt or burn when exposed to high heat or flames. Always exercise caution, keep potential fire hazards away from it, and keep an eye on open flames.
