If you frameless glass shower door leaks or you have a hard time getting it open, it likely needs adjusting. Frameless glass shower doors are made of tempered glass pieces, and they have a thin frame (semi-frameless) or no frame since the glass is heavy. The hinges attach directly to the frame or glass from the top or side. You should be able to make the adjustments yourself by following these steps.
Have you recently had your windshield damaged by some sort of debris? Have you been making excuses as to why you don't need to have it fixed right now? It's not uncommon to for drivers to make excuses as to why they're driving around with a cracked windshield, even if they know better. Some of these excuses seem reasonable at first glance but they are still just that: excuses. For every seemingly good argument that you have to continue to put off replacing your windshield, there are even better reasons why you should have it replaced as soon as possible.
