All of our garden structures are guaranteed for a period of FIVE YEARS from the date of completion against defects in materials and workmanship. Damage due to misuse, neglect, severe storms or impact is not covered under this warranty. This warranty also excludes natural weathering (ie. checking, greying and warping) of the exposed timber components, including the doors. To reduce such effects and to prolong the life of these components, it is recommended that they be painted with a water-based exterior paint as soon as possible after construction and maintained thereafter. The greenhouse film itself is warranted for up to five years under normal conditions but the design of our frames means you can easily expect it to last well beyond ten years.
