In general, uPVC double glazed windows are long-lasting, secure and hard-wearing, however, problems do sometimes occur. The most common issues with double glazing tend to be related to sealed units. Read on to learn about common double glazing problems, and how to handle them.
If you notice draughts coming from your double glazed windows, this is usually a sign that the windows are not closing properly. This is usually caused by one of the two wear-and-tear related issues mentioned above.
To diagnose the problem, close the window and check the side with the hinges. If there is a gap between the sash and the frame, then this means your hinges are damaged. If the hinges look OK, check the lock by sliding a credit card between the sash and the frame. If the card moves freely, then you need to tighten the lock. If the gap is tight, then you have nothing to worry about.
The final likely cause of draughts is a dropped sash. This usually occurs in windows that have side openings. Close the window, and look at the top corner above the handle. If you can see daylight where the sash is supposed to meet the frame, then your sash window has dropped and will need adjusting.
Condensation occurs when water vapour hits a cold surface. Steam, or general moisture in the air, condenses back into water droplets. Usually, having double glazing reduces the amount of condensation that occurs in your home. However, if your home is insulated, draft proofed, and has double glazing then it could become a moisture trap. To determine whether the double glazing window condensation problems you have are indicative of something serious, look at where the water is gathering.
Double glazing is designed to provide insulation, reduce noise pollution, and stop drafts. However, as your installation ages, it is common for the sash to drop, and the hinges to become worn. This leads to several problems:
The most common issues with uPVC windows are rusting, letting in cold air and damaged hardware, including screws, locks and hinges. This occurs from wear and tear, and also when windows are left open for too long and become stiff to open and close. Old uPVC windows are much more likely to experience these common pitfalls due to the low-quality materials and manufacturing processes used when uPVC first emerged in popularity.
However, nowadays uPVC windows benefit from modern glazing technologies which ensure they will continue to perform and look like new for over 25 years. With new uPVC windows, you’ll no longer experience problems of them not closing properly or letting in draughts.
This is one of the most common signs that your double glazed windows need to be repaired or replaced and is most likely from damage overtime or a failure in the window seal. If you’re experiencing problems with your uPVC windows letting in cold air, they’re most likely not insulating your home as they should which means that you will be paying higher energy bills to warm your home. As more energy will be needed, uPVC windows which let in cold air are also much worse for the environment.
No one want’s cold spots in your rooms from draughts entering your home! If you’re experiencing draughts from your existing uPVC windows, there are a few ways that you can fix them, including replacing corroded window locks, fixing broken window hinges and replacing a non-effective window seal which is likely to have shrunk over time.
Although, our expert team will advise you that these are only ‘quick fixes’ and will not last long. Once a window lets in the draughts, it’s a sign that it’s time to replace your uPVC windows as their performance has most likely degraded in other aspects too. Your home security and durability is likely to be compromised as the uPVC window frames will have become much less robust over time.
Broken handles, hinges and locks should not be ignored. As mentioned earlier, damaged hinges that prevent the window from closing correctly lead to draughts, and this essentially eliminates some of the main reasons for having double glazing.
In addition, broken window locks are a serious security issue. Your home insurance may be invalidated if your windows are not correctly locked. For this reason, and your family’s safety, it is important that you fix the problem immediately.
If you live in an older property that has one of the first generations sealed double glazing panes or even a property with UPVC windows and single glazing, then you may find that updating your windows will save you money. Some common problems with older UPVC installations include:
Damaged hinges and dropped sashes can be repaired for you by a specialist.
Issues with seals, however, are more difficult to repair (but not impossible). If you are unsure whether you should repair or replace your double glazing, consult a company such as Window Doctor, who can examine your windows and offer advice, as well as a free quotation.
Replacing your windows will require a substantial up-front investment, but over time that investment will pay for itself. If you do not have double glazing at the moment, speak to your local authority to see if they offer any financial aid for people looking to make their homes more environmentally friendly.
