Every homeowner has, or will, be faced with the question of whether or not to replace their existing windows. Obviously, the answer to this question depends on a number of considerations. Here are the top four signs that you need to look out for with existing double-glazed window units that tell you they are in need of replacement.
Leaks
The first sign to look out for is any leaks around the window frame. This is a sign that the window seal has failed and is letting rainwater through or that the drainage section of the window is blocked. Older double-glazed window units are often prone to this, as they are now out of date, so replacing them with modern, higher-quality units is necessary.
Condensation
Condensation or fog between the two glass panes of a double-glazed unit signifies a big problem. Basically, any moisture forming between the two panes occurs because the seal surrounding the two panes is faulty. Whilst this may not seem to be more than an unsightly nuisance, in reality it means that the gas cavity between the two panes is leaking, causing a significant malfunction of the unit’s insulating role which will affect your energy bill. In some circumstances, only the glass panes require replacement. Window specialists such as Leicestershire replacement glazing experts will be able to give you the best advice.
Chips or Cracks in the Glass Panes
Any crack or chip in the glass requires replacement panes, which can be carried out by many double-glazed window specialists, such as Leicestershire replacement glazing experts.
Draughts
Draughts can be noticed as movements in curtains or when you are standing near to the window itself. All windows will allow a small amount of air infiltration, but this should not be enough to cause a draught. Draughts indicate a break in the seal around the window frame – between it and the brick work. These weather seals can be replaced, although it may be wise to upgrade the entire unit to a more robust modern unit to save money in the long run, as sealant replacement is only ever a temporary fix.
If you notice any of these signs in your existing windows, then it is a good idea to get expert advice from a reputable glazing company.
