The damaged glass in your windows can cause severe damage to your home and even be fatal. You should take the time to ensure that your windows are in good working order.

Single-pane windows are relatively simple to replace and generally fit into frames that were previously in use very easily. If you have double-paned windows which are joined by internal beading, it is harder to remove and replace the panes that were previously in use. In this situation you'll need to source some plastic spacers that will help the new pane to fit perfectly into the frame of the window.

If you're planning to attempt to remove the glass panes yourself, it is essential to wear appropriate safety gear that includes gloves with a thick layer of material and eye protection. It is also recommended to lay down a drop cloth before you start working on the glass, so that any shards will fall on the fabric instead of onto the floor where they could be trodden under and cause further damage.

If you are unable to reposition the hinges you may require replacing the seal. As time passes, rubber seals lose their elasticity and become dry which causes them to lose tightness. If this happens, it's important to replace the seal as fast as possible so that your uPVC windows are watertight and safe from drafts.

UPVC handles can also become loose. Most often it is due to screws that have come loose over time. However, it can occur because the handle mechanism has been worn out. It's a good thing that it's simple to fix the handle of a window that is loose yourself. The first step is to close your window and do a test fit. The joint at the corner of the sash should be aligned with the joint on the casing. If it isn't, you can use the screwdriver to loosen the handle. Then, turn the mechanism back into place.
