Spray Treated: Our sheds and summerhouses get a beautiful golden brown spray treatment before leaving the factory in order to preserve the quality of the wood up until the delivery. As this only lasts through the transit stage, we do advise treating the wood after installation to protect and preserve it, as well as annual maintenance.
Pressure Treated: For an extra level of protection, you can opt for a pressure treated building which is an effective way of keeping the wood long lasting. This is an extra step in the manufacturing process where the wood is treated in a pressurised tank. Chemical preservatives are forced deep into the wood’s fibres to resist rot, decay and termites. When you upgrade to Pressure Treatment, the guarantee is extended from 10 to 15 years.
All garden buildings should be assembled on a firm and level base. A base will ensure your building has a solid, long-lasting and well-drained foundation.
If you want to build your own base, from a sturdy material such as concrete or flagstones, you can find minimum dimensions for each size of this building in the tech specs. In order to protect your building from moisture, you should leave a 2ft gap around the exterior of your building, so remember to take this into consideration when laying any sort of base.
Our robust and simple to use EcoBase provides you with a firm, long-lasting foundation with suitable drainage for your garden building. It is quick and easy to install through the use of snap connectors that link the grids to each other.
The building should be treated once fully assembled and within one month of receiving the product. Always consult the directions on the treatment that you have purchased.
Delivery Once your order is placed we endeavour to send out an acknowledgement email, providing you with the applicable contact details as provided to us, your order reference number and estimated delivery date. In most cases, you will be contacted prior to that estimated delivery date to notify you the day in which your delivery will be made.
