How new are the windows in your home? Do you have problems when you're trying to open them, such as they don't stay up or simply won't budge? How about when you walk by them, do you feel a draft because their seals are shot? When this happens, what's the first thing you think? More than likely it's "I need to replace them ASAP". If you think this way when it comes to your home, then why not the same when it comes to your business?
