Every commercial place has to be in good shape. The floor is usually the most affected from daily usage. Once per 3-6 months will keep the premise in excellent condition with no risk of damage. The floor repair includes nailing and floorboard reclaiming. It's good to apply varnishing to seal the surface, but if you wish to avoid extra expenses, it may stay on this way.
A repair of commercial place is usually after the hours of operations, and it's done in a short period of time. So, if you start today, your guests tomorrow will see the difference.
