Protecting Your Investment

After your new wine cellar is up and running there is one final and important step to best protecting your investment; begin planning a routine maintenance schedule with your contractor. We suggest at least an annual inspection of your equipment to keep it in best working order. Environmental issues cause the majority of equipment failures. Some of which may not be covered under warranty but nearly all are avoidable with regular maintenance and inspection.
