In the first part of this guide to installing a replacement slider window, you learned how to remove the old slider window without causing too much harm to the window frame. In the second part, you will learn how to install the replacement slider window and how to avoid basic problems with your installation. Slider windows are very popular in homes or spaces without much room, but if you don't install them correctly, then you will have endless problems with them. Fitting your replacement slider window should not take too much time, and if you do it correctly, then you will have a durable and effective window for your home.
Step 1 - Measure the Window
Before you do anything else, you should check the size of the hole in your window. Not all slider windows are the same size and shape, so you should try and ensure that your replacement slider window is of roughly the same proportions as your old window. If it is not, then you will need to construct a framework to hold the window, either by enlarging the hole or reducing it to fit. You should also try and find a slider window which has a slim width, as the thickness of the window can affect how it fits into the frame and how you install it. If you do find a slim profile, you will have to nail it down tightly, as they can sometimes be movable during high winds.
Step 2 - Clean the Window Frame
Before you begin installing the window, make sure that you thoroughly clean and caulk the edge of the window frame. This will ensure that you get a good fit for the window and that there are no gaps though which wind and insects can enter your home. You will be best off using a cleaning solution and also cleaning off your replacement slider window.
Step 3 - Install the First Pane
Take your replacement slider window up to the window frame and push it into position. Before you begin nailing the window into position, use some shims to get the panes perfectly level. Once the shims are pushed into place, you can begin nailing the edge of the window to the frame. Turn the locking mechanism so that the window is in the shut position.
Step 4 - Installing the Second Pane
With the first window in the shut position, take your second pane and slide it slowly across the first. You should then be able to move it onto the running tracks of the window frame, which will allow you to move this part of the window backwards and forwards. Attach the sliding mechanism to the edge of the second pane and move the window backwards and forwards several times to ensure that there is free movement. Nail the sliding mechanism tightly to the pane and then seal the outer edge of the window using caulk.
