• When installing new windows, especially with a different configuration.
• When planning a major renovation or refinishing of window frames. Removing the sill can simplify the process.
• Connecting a balcony to a room to create one space may require dismantling.
How to remove a window sill correctly
Removing a plastic window sill is a job that requires attention to detail and care.
Let's start with the sills: the type of sill determines the method of removal. Polymeric frames are usually attached to the wall and window frame with glue and corners. Use a construction knife to carefully hook the edge of the window frame to separate it from the wall, then unscrew the screws or self-tapping screws securing the corners and remove the polymeric window frame.
Plasterboard cornices are normally fixed to a frame made of metal profiles. First remove the plaster or putty covering the seams of the plasterboard, then unscrew the self-tapping screws and remove the edgebanding.Dismantling plaster cornices is more difficult and requires more work. Use a hammer and chisel to gently knock off the plaster, taking care not to damage the wall and window frame.
Next we move on to separating the plastic sill plate from the lower part of the window frame. If the window sill has been installed on prefabricated polyurethane foam, the process will be relatively simple: use a crowbar to gently pry up and separate the plastic window sill panel.
But if the window sill has been self-tapping, use a screwdriver or an electric screwdriver to unscrew the self-tapping screws and then use a crowbar to prise the window sill panel apart.
A window sill mounted on metal brackets is removed in a different way. First, unscrew the screws that secured the window sill brackets. Then remove them and separate the sill plate.
Finally, we dismantle the window sill itself. If it was installed in a brick or concrete wall, the window sill may have been reinforced with cement mortar. In this case, use a hammer and chisel to gently knock out and remove the old cement mortar around the sill.
If the window sill was built into a wooden wall, the sill panel may have been nailed or self-tapping to the wood. Then use a nail puller, an electric screwdriver or a screwdriver to remove these fasteners.
After you have gone through all the steps of dismantling, from the preparation of the tools to the careful removal of the old window sill, you can now successfully tackle the task on your own.
Now you have the opportunity to transform your window space by installing a new interior element to suit your requirements.
To understand how to replace a modern plastic window sill with your own hands, you need to have an understanding of the dismantling steps. Take into account the properties of the material (in this case plastic).
