How to Repair Double Hung Casement Windows How to Repair Double Hung Casement Windows
Double hung casement windows are an attractive and interesting addition to any home. Windows that are hung vertically, however, can often be prone to problems that conventional windows are not. With a little time and patience, you will be able to diagnose and repair most issues with double hung casement windows.
Step 1: Pry Stops off of Windows
Using a pry bar, begin to remove the stops and trim from the inside and outside of the casement windows. If the stops are sealed to the frame with paint, you can use a utility knife to help loosen them. Be careful when you are removing trim pieces to avoid splitting the wood. Trim will most likely be nailed in place, so apply steady pressure on the pry bar just above and below each nail to remove the trim.
Step 2: Remove Windows
Swing one of the windows open and loosen any bolts that are attaching the windows to the window frame. In order to do this, you will need to use a screwdriver and a hammer to remove the bolts one by one from their hinges. If there is any sash cord or rope attaching the window to the frame, cut it with a utility knife. Once the window is removed from the window frame, repeat the procedure on the other side to remove the other window. If any of the bolts are bent or rusted, you will need to replace these parts with new parts from your local hardware store. If you find that the frame of either of the windows themselves are warped or show signs of mildew, this will also mean that you will need to replace them.
Step 3: Oil Joints
One of the most common problems that can occur with casement windows is that they can become squeaky or difficult to open and close. This can be caused by several issues. As noted above, the bolts or hinges of the windows may become bent or rusted over time. If this is the case, you will most likely have to replace the damaged parts entirely. In some cases, however, you may be able to fix the issue by simply oiling the joints so that they move against one another more easily. After taking apart the joints, place them on a towel and spray them all thoroughly with WD-40. Polish the pieces to make sure they are not dirty or grimy before replacing them.
Step 4: Replace Stops and Trim
Once you have replaced and/or lubricated the joints attaching the windows to the frame and hung the windows in place once again. At this point, you will need to replace the trim pieces and wooden stops that you removed in step 1. These pieces will have to be nailed into place in the same positions that they were in before you removed them. Once these pieces are returned to their original positions, make sure that the windows are working in a satisfactory way.
