One of the key factors you should consider when renovating your business is the time period in which your renovation would take place. Is slow or fast for your business? For example, most malls are not going to think about renovating during the extremely busy holiday season. It will create more congestion in the crowded mall for smaller renovations, and shutting down the mall completely for a large renovation will create a huge loss in income. Try to time your renovation around a period that is traditionally slow for your business or industry.
