Important Information

Our pressure treated buildings come with a 15 year anti rot guarantee* and offer a high level of protection against weather damage, rot, decay and insect attack. For maximum protection, once installed we do advise applying a waterproofing treatment to your garden building to prevent water ingress. All our buildings also include a 1 year manufacturer's guarantee* as standard.

Pressure Treated Buildings

Modern pressure treating techniques are environmentally friendly, using water-based treatments. However gloves should be worn when handling the parts/assembling the garden building.

Pressure treatment is different to externally applied preservatives and top coat treatments. Chemicals are impregnated into the fibres of the wood under pressure. This is done prior to assembling the building at the factory. By fixing chemicals into the wood, pressure treating offers protection against insect attack, chemical attack and natural decay. The building should also be treated with a waterproofing topcoat. While the effectiveness of the treatment does not alter without a top coat, the colour does change over time.

Our buildings are supplied flat packed as DIY kits with full instructions.

It is the customer's responsibility to follow the instructions outlined in Aftercare.

All of our buildings are delivered unpainted. The buildings are dressed for display, we don't supply any accessories or shelves featured within the product images.

Exact product dimensions are supplied on the listing as we do round off the main size of the building in order to make it easier for customers to find, so please be sure to check the item's specific measurements carefully.

All measurements refer to the exterior of the building which includes the roof overhang unless stated otherwise.

Our styrene windows are protected using a clear film which will need to be removed after you've installed the building.

Delivery times highlighted with an asterisk (*) refer to working days.

15 Year Anti-Rot Guarantee

Our Pressure Treated Garden Buildings come with a 15 year anti rot guarantee. Pressure treating is a chemical process which helps to protect wood against rot and insect damage. There are many different treatment solutions, the most common chemicals used to pressure treat wood are Alkaline Copper Quaternary (ACQ), Copper Azole (CA), and Micronized Copper Quaternary (MCQ).

Safety: When handling pressured treated timber, be sure to wear gloves and avoid inhalation of sawdust. Do NOT use in contact with food and drinking water or as animal bedding. Dispose of treated wood responsibly, industrial waste should be disposed of through an authorised waste contactor.

Always wear gloves, eye protection and a dust mask when handling wood. Due to chemicals in pressure treated wood, never burn its sawdust or scraps; instead dispose in a landfill.

In order to keep your building looking great, it will need re-treating at least annually. Always use a high quality waterproofing topcoat, applied in accordance with the the manufacturer's instructions. If left untreated the colour will fade from green to silvery grey in approximately 6 months. For more information please refer to the Waltons T&C's.

1 Year Manufacturer's Guarantee

Subject to the conditions set out in the T&C's (Section 8) the Seller warrants that the Goods will correspond with their specification at the time of delivery and will be free from defects in material and workmanship for a period of 12 months.


We want you to enjoy the use of your new garden building for many years. To give you the best chance of doing so, your product needs protecting at the start and maintained during its life. If you're planning a DIY project, please read our Self-Installation & How to Build a Shed advice pages before you start.


All long-lasting garden buildings will have been built on a solid and level base, either concrete, slabs, a wooden frame or ground level bearers. A flat, level base is essential, for more information go to our How to Build a Shed Base guide.

If your garden building is not level and square when built, it will twist and warp with the natural movement of the wood. The first signs of this are when the doors or windows stop opening and closing properly. You may get issues with the roof and potential gaps in the panels which will allow water in, there may be flex in the floor and probably creaking. Check your base is level in both directions and adjust prior to the build. It will be really difficult to adjust afterwards.


Our styrene windows are protected using a clear film which will need to be removed after you've installed the building.

All Waltons shed windows are designed to fit well, but over time and with the movement of wood, small gaps can appear. Help to prevent this by sealing your windows with a silicone sealant. You can do this either when you build your shed, or add it to an existing one. We've created this video Protect Your Shed - Silicone Window Sealant for guidance.

We've also created these handy Maintenance Guides to help you make the most out of your building, for years to come. Should you require any further advice, you can contact our Customer Service Team on 0800 029 1000 and select Option 3.

Review:Base Build:
The base is simply not strong enough with just a single sheet of plywood, I had to build my own 4x2 base to give it any support, else I really felt in danger of going through the floor as I walked on it. I then purchased some additional plywood to strengthen the floor.

Our Reply:Good afternoon,

Review:Had to renew the floor and roof boards as they were very thin, and the ultra thin perspex windows are just silly, no love was put into making the shed at the factory, missed nails, split wood every were, the doors had to be planed down as they didn't fit.
So from taking the easy route to save me...
