Tradesmen with the right qualifications can fix or replace hinges mechanisms, handles, and seals. It is possible to do some repairs yourself, however it is often more time-consuming than hiring a professional to do it for you. It is also safer. 1. Broken Panes Double pane windows make use of the space between the two panes to create an airtight seal. This helps keep the heat inside and cold outside. However, this seal can be compromised by a physical abrasion or exposure to extreme temperatures. It is crucial to repair double pane window cracks as soon they occur. A small crack could get worse in time, leading to a broken double pane window. It is best to call an expert if you have a broken window. They'll locate a replacement that will fit your frame. They will then install the new window and ensure that it's secure. Before installing a new window, it is important to take off any old metal or putty glazing points.

Condensation Many owners of double glazing will encounter condensation at some point in the life of their windows. Usually, this is caused by the lack of air circulation in rooms or humidity issues, which causes cold surfaces like windows to draw moisture from warm air. This is especially a problem in bathrooms where excess steam can flow through the window, and cool to create condensation. Since this moisture is trapped in the insulating gap between your glass panes it could cause heat to be lost from your home or building - which will result in higher energy bills for you. If left unattended for a long time the condensation could cause mould and damp in your home, which could require professional attention. You should open your windows daily in the morning, unless it's extremely cold. You should also keep the open the vents for drips when you are out. You can also use a dehumidifier at home to help absorb excess water and stop it from becoming a problem on cold surfaces, including your double glazing.

This is a costly fix but it will keep your home or building more energy efficient and warm. Check if your double glazing is still covered by the warranty. If it is the installers will repair the window units at no cost. Avoid DIY fixes for condensation, because this could void your warranty. 3. Leaks Water droplets or mists between the panes of your double glazing is an indicator that there's an issue with the seals of your window. This does not necessarily suggest that you need to replace the window. It is fixable by replacing the caulking. A common cause for this issue is the fluctuating temperatures that cause the frames of double-glazed doors and windows to expand and shrink. This can result in gaps appearing around the frame that over time will create draughts and let water seep into the home. Another reason is that, over time, the gas used to insulate the window may become dislodged, which could create an air draught, and allow moisture to enter the home. If your double-glazed windows are difficult to close and open cleaning them with cold water may temporarily solve the problem until warmer weather returns. The majority of double glazed windows and doors are covered by a guarantee from the company that installed them.

Damaged Glass Double-glazed windows are supposed to provide insulation to your home and keep cold air out and warm air in.
