What Is NOT Covered:

This warranty covers return freight of any warranted product only for the first year. This warranty gives you specific legal rights and you may have other rights which vary from state to state.
Wind Damage:
Treasure Garden highly recommends that no umbrella, regardless of size or weight, ever be left unattended in the open position. In windy conditions, it is further recommended that umbrellas be closed, removed from their base, and stored, or laid horizontally. This will reduce the risk of damage to your umbrella, furniture, and other belongings or property. To ensure stability of your umbrella, please observe proper placement, and use sufficient weight (base). The Treasure Garden catalog contains minimum recommendations for necessary weight; but this can vary, depending on the conditions in your particular area.
Rust is a natural part of the aging process of all Steel or Iron based materials and is therefore NOT considered a defect. Treasure Garden Cast Iron & Steel plate bases are designed to require minimum maintenance. Bases should be kept clean. Do not let dirt build up on the bases. Cleaning with mild soap and water, and seasonal touch-up of any scratches, chips or occasional rust see page from crevices or hidden, un-finishable surfaces inherent in some designs is all that is required. Touch Up paint in matching frame colors are available. Never leave bases standing in water. To keep your bases looking their best, you may wish to store them when not in use for an extended period of time.
