How do you know your double glazing needs replacing?
Broken or damaged double glazing can significantly impact the thermal efficiency of your home. Perished window seals cause draughts in the room and condensation to form on the glass. This results in higher energy bills as your boiler is having to overcompensate for the heat escaping through the damaged windows and doors to maintain a warm temperature in your property. This article will cover the main signs that your double glazing needs replacing and what action you should take.
What is the most common sign that my double glazing needs replacing?
Double glazing is made up of two panes of glass within a sealed unit – when this seal is broken or damaged, moisture and water can seep through the unit, causing condensation or misting to form inside. Not only will this significantly reduce visibility through the glass, but it can also lead to considerable heat loss. The intricacy of the problem makes it impossible to clean or repair, so replacement is the most suitable solution.
The three main causes of misted or cloudy double glazing are:
- Poor installation
- Damaged or faulty seals
- Age
What are other common double glazing problems?
Double glazing that has become difficult to open or is sagging and catching on the window frame can be caused by changing weather conditions. Extreme temperatures can cause the frame to expand or shrink and it’s this movement that will prevent your window or door from opening and closing as smoothly as it should. Not only can this lead to significant heat loss, but it also poses a security risk, leaving your property vulnerable to opportunistic thieves.
If the problem persists, then you will need to contact an expert as soon as possible who can assess the situation and carry out the relevant remedial action.
Should you repair or replace your double glazing?
Some minor double glazing problems can be repaired through simple checks such as applying oil to the hinges and handles, or tightening the hinges and other mechanisms in case they have moved or become loose.
However, in some circumstances, replacing double glazing is the most suitable option. It’s highly recommended that you get in touch with a double glazing expert who will be able to tell you whether your problem can be repaired or will need to be replaced.
Any condensation, cracks, chips or holes in the glass are key indicators that the double glazing needs to be replaced as the problem cannot be rectified any other way. Other key signs to look out for that point to the need for a replacement double glazing unit are:
- Draughts
- Water leaks
- Excessive noise
- Yellow uPVC frame
- Cracked timber frame
How long does double glazing last?
The average lifespan of double glazed windows is a minimum of 20 years. This can depend on a few different factors, including:
- Weather conditions
- Manufacturing quality
- Installation standard
- Maintenance
Developments in technology and materials have meant that the thermal performance of double glazing has improved considerably in recent years, so there’s no better time than now to have your windows replaced if required.
Can you repair or replace double glazing yourself?
Double glazing installations must meet the requirements of relevant building regulations and must adhere to certified standards. As such, you should leave any work to a qualified expert to ensure that it is safe and compliant.
Don’t just think about the here and now, look to the future – any improper installations can affect the sale of your house in the coming years.
