Double Glazed Window Repairs
Double glazing can be a fantastic investment for your home, but it can be a pain when it fails to function correctly. Luckily, most problems can be fixed and you don't have to replace your doors or windows.
Double-glazed windows consist of two glass panes separated by a small gap. The gap is then filled with an insulating gas, like the gas argon. This makes windows more efficient.
Broken panes
Double-paned windows are harder to break than single panes of glass but they can still shatter or crack. It's important to fix the broken pane of double glazing as soon as possible to avoid moisture and energy loss.
Depending on the degree of the crack, you may decide to use a temporary fix or go for more extensive epoxy repair. A temporary repair can aid in preventing further cracking, and keep out cold air and rain. A more extensive repair may make the crack stronger and provide an improved seal.
To replace a damaged double-pane window, first take the frame from the sash, and then set it on the table. Apply a grid of duct tap over the pane to stop glass fragments from falling during removal. Once the tape has been installed, remove the old double-pane glass from the frame. Then clean the rabbet and grooves with a wire brush and vacuum or wipe them with a damp cloth. If needed, take off the wood molding and scrape away all metal or putty before installing the new pane. Apply silicone caulk into the rabbets and grooves in order to ensure a snug fit.
If you're fixing a damaged glass by yourself, begin by sanding it until it's smooth and free of paint. Heating guns can be used to soften any putty or glazing. Once the rabbet has been cleaned, you can use a putty blade to press ropes into place. Make sure the putty is a uniform thickness and press against the glass and frame in a uniform way.
If you are looking for the long-term solution then you could opt for an epoxy repair instead of replacing. This is more expensive and will require a longer wait time, but can be more appealing. It also lasts longer than an immediate repair.
Condensation
Condensation is one of the most common double glazed window issues, but it doesn't necessarily mean your windows are defective. It's a good thing your windows show condensation. This indicates that double glazing is working just as it is supposed to, preventing the cold and retaining the heat.
If you notice condensation appearing on the outside of your window, it is actually water vapor from the inside of your home that has cooled down and condensed onto the surface of the glass. It's a natural phenomenon that isn't harmful to your windows in the event that you don't leave it on the surface too long.
The cause of internal condensation is usually a lack of humidity or low temperatures in the room. This creates cold surfaces, such as windows which draw in moisture that is high in dewpoint (the temperature where water turns into liquid). Humidity is also inevitable around kitchens and bathrooms due to steam from showers or kettles as well as hot pots and pans that are used for cooking.
Avoid hanging www.repairmywindowsanddoors.co.uk to windows, and make sure your uPVC frames are properly ventilated to avoid moisture buildup. Also, ensure that your double-glazed windows are correctly insulated and installed with the right gap (6mm is ideal) to ensure maximum energy efficiency. You could also try adding one-way air vents to your windows to improve insulation. If you're still getting condensation, however, then there's an issue with the gaskets or seals and this is definitely a job for a professional.
Draughts
A double-glazed window that is draughty is an indication that the seal between your glass panes has failed and needs to be replaced. This can impact the insulation of your home and also increase energy costs.

Smudging
Double-glazed windows are made up of two panes that have an air spacer or dense gas between them to make an effective seal that stops heat from passing through the frame. They are a great method to conserve energy and reduce the carbon footprint of your home. However, double-glazed windows can encounter a myriad of issues that could impact its performance and durability. These include condensation, mist, and being difficult to open or close.
The difficulty in opening your double-glazed windows could be caused by the weather or it might be a fault with the hinges, handles or mechanism. Cleaning them with cold water and lubricating them can help to solve the issue, however you must contact the company you bought windows from as soon as possible to have it repaired.
If your doors or windows have sagged or dropped over time, this is a common problem that can be fixed by a trained professional. It is a good idea to check your warranty to see if there are any repairs covered.
Fogged or foggy glass can be caused by the presence of moisture between the panes. It's usually a sign that the seals aren't functioning properly or your double-glazing unit requires to be replaced. It's a relatively straightforward fix and you'll often get it done without having to replace the entire window, which can save you money.
To address this issue technicians will make tiny holes to vent any moisture between the glass panes and other parts of the window. Once the moisture has been removed the new antifog coating is applied and the window is sealed. Sometimes, the window may need to be removed but, in most cases, it can be done within the home.
Mist
Mist can be a big issue for older double glazing, especially when it happens on the exterior and the interior of the windows. This is caused by an issue with the seal designed to prevent moisture and air between the two panes. During the manufacture of double-glazed units the seal is made by sealing both panes with an airtight butyl or polysulphide seal around the edges of the glass and the spacer bar. This seal is designed to keep the window from leaking, and also provide insulation. If you have misted double glazed windows it can be difficult to remove and clean, since you will need to break through the hardened seal in order to clean.
The issue with mists is that they permit moisture to get in, which leads to condensation between the glass panes. This is because there is huge differences in temperature between the external and internal surfaces of the glass. The moisture is then trapped within the spaces and gives the appearance of a milky white. This can be very unattractive and is difficult to remove.
There are a number of companies that claim to be able to repair your double glazed windows that are misting by drilling holes into the unit and injecting chemicals into the holes. Then, they absorb the moisture from within. It's not permanent solution and it's much easier to replace your entire double-glazed unit.
It is recommended to keep your windows clean and well-ventilated regularly. Make use of extractor fans to minimize the amount of moisture that accumulates in kitchens and bathrooms. Clean windows with a wet cloth to prevent this. If you can't avoid the issue, we suggest that you replace windows that are double-glazed with A-rated units to improve the efficiency of your energy bills.
