Does your insurance company just mail you your renewal, does the insurance company look at it? Do you even look at it? Since your needs and risks are ever changing it is always a good idea to review your policies with your agent at least on an annual basis. Even if no changes are needed, at least you know you have the protection you need and aren't paying for coverage you may no longer need.
Sometimes just changing your deductibles are all you need to do in order to save considerably. If you currently have a 500 deductible, find out how much to go to 1000? You may find that you can save 500 in only a matter of 2-3 years. If you don’t have a loss in the next 2-3 years, you will surely be ahead.
Insurance is paying for peace of mind, if you review your policy with your agent annually you will indeed have less surprises and have the peace of mind you are paying for.
