uPVC, a long-lasting material that is energy-efficient and long-lasting, may crack over time. A cracked window can be more than an eyesore. It can let cold air in your home, and also increase the cost of electricity due to the fact that heat escapes through the crack. It is possible to fix the cracks in a uPVC frame without spending a lot and it’s possible to do it quite quickly.

The first thing you need to do is to determine the source of the crack. It could be caused by a sudden shift in pressure, for instance when you open or close the window.

Another reason that can cause a crack in your uPVC window is when the window frame or sill has become out of alignment. This could be due to moving furniture, settling into a new property or even weather conditions like freezing temperatures. It is easy to fix this issue by drilling a few pilot holes, and then running a line of silicone across the gap. This will block any moisture from getting into the window.

Clean your uPVC windows regularly to keep them looking good and functioning well. This means wiping the frames using a white cloth that has been submerged in soapy or solvent water.
