The Best Tips You'll Ever Receive On Double Glazed Window Repair Double Glazed Window Repairs

Double glazing can be an excellent investment, but it can also be frustrating when it doesn't perform. Luckily, the majority of issues are fixable and you do not need to replace your doors or windows.


Double-glazed windows are made up of two glass panes separated by a small gap. The gap is then filled with an insulating gas, like argon. This increases a window's thermal efficiency.

Broken panes

Double-paned windows are harder to break than single panes of glass but they can still shatter or crack. If a pane is broken in your double glazing, it's crucial to repair it immediately to prevent moisture and energy losses.

You can opt for a temporary repair or a more intensive epoxy fix depending on the degree of the crack. A temporary repair can stop further cracks from occurring and keep out rain and cold air. A more extensive repair will strengthen the crack and create a stronger seal.

To replace a damaged double-pane window, first take the frame from the sash and place it on a table. Then, put a grid of duct tape to the pane to stop any glass pieces from falling off when you remove it. Once the tape has been applied, remove the old double-pane glass out of the frame. Next, clean the grooves and rabbet using a wire brush, vacuum or wipe them with a damp cloth. Remove the wood molding, if required and scrape off any metal glazing points or putty before installing the new pane. Then, apply a silicone caulk to the grooves and rabbet to ensure that the fit is secure.

If you're fixing a damaged glass by yourself, start by sanding it until it's smooth and free of paint. You can also use a heating gun to soften any glazing or putty points. Once the rabbet has been cleaned and dried, you can use a blade for a putty to press ropes into place. Make sure the putty is an even thickness and presses against the glass and the frame in a uniform way.

If you're looking for a long-term fix an epoxy repair is a better choice over replacing. This option is more expensive and has a longer waiting period however, it is also more attractive. It will also last longer than an immediate fix.

Condensation

Condensation is a typical issue with double-glazed windows but that doesn't mean they're defective. It's a good thing that your windows show condensation. This means that double glazing is working exactly as it is supposed to, keeping out the cold and retaining the warmth.

It's actually water vapour from your home which condenses on the glass's surface when you see condensation. It's a natural process that won't harm your windows in the event that you don't leave it on the glass for long enough.

The reason for condensation inside is usually too much humidity or low temperatures in the room. This results in cold surfaces, like windows, to draw in moisture with a high in dewpoint (the temperature at which water turns into a liquid). The steam from showers, kettles and hot pots and the cooking pans can also cause a lot of humidity around bathrooms and kitchens.

To prevent condensation, try not to hang wet clothes near your windows and always ensure that your uPVC frames have plenty of air circulation to avoid the accumulation of moisture. You should also ensure that your double-glazed windows are properly insulated and fitted, with the right gap (6mm is best) to maximize energy efficiency. You can also add air vents that are one-way on your windows to increase the insulation. If you're still experiencing condensation, however, then there's likely an issue with gaskets or seals and this is something that should be handled by a professional.

Draughts

A window that isn't draughty is an indication that the seal between the glass panes of your double-glazing has sprung a leak, and is likely to need replacing. This can affect the insulation of your home and can cause an increase in your energy bills and therefore it is important to act fast when you spot this issue.

Window repair services can replace your sealed unit, restoring efficiency to your windows. They can also upgrade existing frames with energy-saving features, such glass units filled with argon and thermal spacer bars to cut down on heat loss, and reduce your heating bills.

It's also worth examining the locking mechanisms on your double-glazed windows. Older uPVC window locks are notorious for becoming stiff over time however it's easy to fix this issue by lubricating them regularly with a specialized uPVC cleaning product.

A professional double glazing company carry out your repair work will ensure that the repair is done correctly. They'll have the appropriate tools to ensure that your window is completely sealed and watertight. RepairMyWindowsAndDoors can also repair any damage to the frame so you can take advantage of your new double glazing.

If you find any of these issues, call your local double glazing repair company immediately to fix them as soon as possible. You'll be grateful that you did it. A double glazing installation well-repaired will give your home an immediate sense of quality and save your energy costs!

Smudging

Double-glazed windows are made up of two separate panes with an air spacer or dense gas between them to create an effective seal that stops heat passing through the frame. They're a great option to reduce energy consumption and the carbon footprint. Double glazing can have many issues that can impact its performance and life span. These include condensation, mist, and difficult to open or close.

Difficulty opening your double glazed windows could be due to the weather or it could be a problem with the hinges, handles or mechanism. Wiping them down with cold water and then lubricating them can alleviate the issue, but you should contact the company you bought windows from as quickly as possible to have it repaired.

This is another common problem that is easily fixable. It is always worth checking your warranty to see whether there are any repairs covered.

Foggy and fogged glass can be caused by moisture between the panes. It's typically an indication of damaged seals or an old double-glazing unit that needs to be replaced. It's a relatively straightforward fix and you'll often do it without having to replace the entire window, which can save you money.

To correct this issue A technician will drill tiny holes to vent out any moisture between the glass panes and other parts of the window. After the moisture has been removed the new antifog coating is applied and the window is sealed. Occasionally, the window may require removal prior to this happens but most of the time, it can be carried out from the inside of the home.

Mist

Mist can be a big problem with older double glazing, particularly when it happens on the outside and inside of the windows. It is due to an issue with the seal designed to prevent air and moisture out between the two panes. During the manufacture of double-glazed units the seal is made by sealing both panes with an airtight polysulphide or butyl seal around the edges of the glass and the spacer bar. This is intended to create insulation and prevent the window from being leaking. If you have misted double-glazed windows, it may be difficult to remove and clean, as you'll need to break the hardened seal in order to clean.

The problem with mist is that it allows moisture in which eventually causes condensation between the panes of glass. This is due to an enormous temperature difference between the external and internal surfaces of the glass. The moisture then gets trapped in the gaps and causes the appearance of a milky white. It can be very unsightly and can be difficult to eliminate.

There are many companies who claim to be able to repair your double-glazed windows that are misting by drilling holes into the unit and injecting chemicals through the holes which then absorbs the moisture within. However, this isn't an end-to-end solution to the issue and it is far easier to replace the entire double-glazed unit if suffering from misting.

It is recommended to keep your windows clean and ventilated regularly. It is also a good idea to use extractor fans in bathrooms and kitchens and clean windows with an damp cloth to minimize the build-up of moisture. If you're unable to avoid the issue completely, we recommend replacing your double-glazed units with A-rated ones to improve energy efficiency.
