Window hinge replacement is a very common item for all double glazing window repair company’s. Friction hinges, as they are known, because of the usually black or grey plastic plate with a small brass screw in the middle of the hinge that causes the window to stop at the required opening, break relatively easily if not maintained properly.
What often happens is they are not lubricated with WD40 before they are shut for the winter then they seize onto the hinge itself and when you try to open the window it won’t move, so is forced open and the afore mentioned plastic friction plate snaps in half usually right across the small screw hole, it is then very difficult to even get the window to close properly just to lock it until you can have the hinge replaced.
You can replace these hinges yourself but you must make sure the replacement hinge is the same as the one you are taking out, the vast majority come in 13mm and 16mm stack heights older aluminium windows are mostly 13mm and the vast majority of upvc are 16mm,but this is not always the case and must be checked properly.
Then the length of the hinge most top/hung windows that push out from the bottom will be either 6, 8, 10, 12, 16, 20, or 24 inches and most side/ hung windows with the handle on the side 12 or 6 inches. You also need to take into consideration the location of the window, if in the bedroom, for example, a fire/hinge is required for 90 degree opening in case of a fire. If changing hinges on a bedroom window that doesn’t have fire hinges, it’s a good idea to install fire hinges. They are not that much more expensive and besides the safety aspect they will make the window easier to clean.
If you are in anyway unsure about the type of hinge you need call a double glazing window repair company and let them do it for you because if you get it wrong you won’t be able to shut your window.
