How to Repair Double Glazed Windows
Many homes with double-glazing encounter issues with condensation, a lower insulation quality and windows that are difficult to open. These issues are typically caused by problems with the hinges or handles.
You can repair these windows with a few easy steps.
Cracked Panes
If a double-pane window has cracked, it's a serious problem that needs to be addressed quickly. When a double or triple-pane window is damaged, the gas that insulates it will keep out cold air and warm air in winter months escapes. This means that your home is less well-insulated. Cracks also worsen over time, so repairing them now prevents a potentially more serious issue in the future.
The most important step to take when you notice cracks is to determine the cause of it. The most frequent cause is a structural issue which can cause the break, but it's possible that it was caused by an impact of some sort. In this case it is imperative to check your other windows for damage and determine the next steps.
It's also a good idea to inspect the area around your home for any other issues that could be causing the crack. If your windows are near other doors or walls the stress caused by temperatures can be causing cracking.
Depending on the cause of the crack, there are various ways to repair it. If the crack was caused by an injury, you might be able replace just the broken glass. Alternatively, you might need to replace the entire window frame. This is a more complex solution and requires the assistance of an expert.
If you've noticed cracks in the glass that didn't cause the frame to move then it's usually simple to apply adhesive between the broken panes. This will close the crack and prevent further damage to your window.
Covering the crack using clear tape is an alternative option. It's not the prettiest solution, but it prevents drafts and bugs getting into your home. Glass repair film is an upgrade that can be applied quickly and offers a more solid degree of protection. upvc window repairs glazing companies offer this service, which is worth the investment to safeguard your windows.
Condensation Build-Up
Condensation that builds up between the panes of double glazing is one of the most common reasons why people have to fix their windows. It's usually a sign that a seal between two window panes was not strong enough, allowing water to enter. This moisture can cause condensation, as well as other issues that could require replacement of the window.
Double glazing is more effective at decreasing condensation than single pane windows since it features a space between the glass that is either filled with air or gas that is not toxic. The space is then separated from the window frame by a spacer bar, which acts as an insulation to stop heat loss. In many instances the spacer bar has silica gel which is effective in preventing moisture from getting between the glass panes.
It is therefore important to regularly wipe down and clean your windows. This will decrease the amount of moisture that builds up and let it evaporate. Using extractor fans or opening the windows to allow for more airflow can also help to remove moisture.
Installing a dehumidifier can be another method to fight condensation. These units can be purchased for between PS60-PS150. They are a great investment that will not only decrease condensation, but also prevent the growth of mould in your home, too.
Condensation may occur between the glass panes in your double glazing as the air outside may be warmer than the inside window pane. This causes the glass's surface to cool, which results in condensation. It can also occur when you experience changes in temperature, for instance, turning on the heating or cooling your home.
In reality, condensation may be a sign of a poor double glazing design as some of the older models are constructed with rubber strips instead of the more modern silicone version, which can deteriorate over time. In some cases it's possible to have your seals repaired, although it is important to remember that this will only offer an immediate solution since the window will eventually degrade in another area, meaning you'll need to replace it in the future.
Stained Glass
If you're having trouble with a double glazed window handle or lock, it is possible to repair it instead of having to replace the entire glass pane. However, this isn't necessarily a DIY job since special tools are required to ensure the repair is done properly and will not affect the seal or the purpose of the window.
Most homeowners with double glazing complain that their doors or windows are difficult to open. This is usually due to a slight warping of the frame or hinges, but could also be due to issues with the sealing. In some cases the issue could be more severe than this and it is recommended to speak to a professional regarding the possibilities available.
Another common complaint is the forming of condensation between the glass panes. This could indicate that the seal is failing and no longer holding in the gas that insulates between the panes. This is an easy fix. The insulating gas is restored with a special glue to seal the gap.
Place the damaged window on a flat surface. Carefully peel back the black sealant to reveal the silver spacer bar. cut into it using a sharp knife, being sure to stay under the glass's bottom and the silver spacer bar. Cut until you are able to split the two pieces, and after you've done this, place the top piece of glass on your work surface (it is recommended to wear gloves here). Clean the glazed side that faces the frame, as well as the spacer frame. Make sure to get rid of any marks and smears, since these can impact the sealing of the window once it is put back together. And lastly, position the new spacer on the glass pane. Spread the adhesive along the edge to allow it to adhere to the glass and silver spacer frame. Let the adhesive dry before assembling. This is typically a task for two as it can be difficult to align everything.
Gasket Seals
Although double glazing is extremely durable and is designed to last for many years to come, there are still problems that can occur at times. It is crucial to address any issues promptly when they happen, whether it's draughts or problems with opening and closing.
One of the most common problems reported by double glazed owners is the formation of condensation between the two glass panes. This is due to the failure of the desiccant that absorbs moisture in the air inside the insulated gap. Once the desiccant fails the condensation will form within minutes and leave a dark mark on the window.
Another issue can arise when the gasket seal is not able to keep water and other contaminants from entering the gap. This can lead to leaks around the edges of the frame and could also cause damage to the surface of the double glazed unit itself. Contact your installer immediately if you notice any signs that your double-glazed units are leaking.
Many companies will provide a warranty for their products and these often include a guarantee period of 10 or 20 years, and some even offering lifetime assurances. Examine the specifics of your warranty to determine what's covered and the length of time it will last.
It may be worth trying to resolve any hardware issues yourself before contacting your double glazing supplier to request repairs. For instance, you can try cooling the mechanism or lubricating it to see if this fixes the issue. You can also try taking off the handle or window handle and then cleaning it before putting it back in place.
Contact your local council to determine whether they have grants available to help you pay for the replacement or repair of your double-glazed windows. There are numerous ways to apply and some areas will require a particular form of application or evidence of eligibility, so it is always worth checking with your local authority prior to deciding on how to proceed.
