Can Double Glazed Windows Be Repaired?

If you have recently had double glazing installed in your home and they're beginning to show signs of failing you may be wondering if they could be fixed.

You may be able to claim your double glazing under warranty based on the issue and the date you purchased it.

Broken Panes

If a window's pane is damaged or cracked air can flow through more easily. This decreases the effectiveness of the window as an insulation barrier and against the elements. Depending on the time of year, this can cause hot or cold air to enter or escape your home, increasing the cost of cooling and heating.

If the crack in the double glazing isn't too deep, it might be possible to just apply a strong-hold tape. This is only a temporary solution, though, and it may only prevent the crack from getting worse. A professional window repair service can fix any broken glass that has been smashed on your double-glazed windows.

Attempting to replace a broken window pane yourself can be tricky and dangerous. If the crack is extensive and difficult to eliminate, you can try applying strips of masking tap in a crisscrossing design. If the crack is small enough to be able to hold it in place and use a blade to cut it off from the frame. Wear gloves and a mask while cutting the glass. After the pane has been cut, you will need to lay it flat on several layers of newspaper to catch any pieces that may fall.

To install a replacement pane, you'll need to make the frame ready and purchase replacement glass. Find the opening of the frame and subtract 1/16 to 1/8 inch in both directions to make sure that the new pane is a good fit. Cut your replacement glass at a local hardware store or glass shop to this measurement. If you have wooden frames, you can purchase points for glaziers from a hardware shop to install on the edges of your new pane. Place the points in a way that they allow for expansion and contraction, while keeping the putty flush with the glass.

After the new pane has been placed then spread a thick layer of your glazing compound using a putty knife. Use a linseed-oil-based putty like Sarco or a less expensive product like Dap glazing compound. If you notice any gaps between your new pane and the frame then fill them in using your chosen compound. Make sure you smooth the compound to ensure it is level and even all around your pane.

Water Leaks

The occurrence of water leaks around the frame or sash is a typical problem that occurs when window sealant has become degraded and requires replacement. Water leaks around the window can damage the plaster or drywall and cause damp walls.

A double-glazed window that is of good quality has a gasket that compresses firmly when the sash closes. Any water that comes into the area should be drained out through the weep holes located in the bottom of the frame. However, sometimes the weep holes get blocked by a build-up debris and dirt or the weather stripping around the window may need to be replaced.

Another source of water leaks is the lintel, which is a support for the brick that is above the window. Installers who built the house might not have realized the importance of allowing the lintel to drain properly, or they may have covered it in concrete, which left a gap in which rainwater can enter and accumulate, and cause dampness or rot to the wood. The builders should have bent the fascia boards over the window to ensure that the water is directed properly. This will prevent water from entering the building through these gaps.

A gap between the glass panes of a double-glazed window can also be the cause of leaks. It's possible that the gas argon or krypton that should be between the glass to provide insulation has escaped out of the windows because of the seal being worn out. Although this isn't the most serious problem with windows that leak however, it could have a negative impact on energy efficiency. It should be addressed as quickly as possible. In this instance replacing double glazing could be the best option. A professional will conduct a full evaluation, let you know the source of the leak from and recommend solutions. They'll also be able advise whether it makes sense to fix the window or replace it completely. They will also be able to give you a quote for any work that is required.

Condensation

Condensation may be a problem with older double-glazed doors and windows. However, this is generally an easy fix. It is caused by a lack of air circulation around the window. It usually is seen in rooms like kitchens or bathrooms. The most evident sign of condensation is droplets of water forming on the glass's surface. The droplets will quickly evaporate when the window is heated by sunlight. If the issue persists it is worth investigating further.

Another indication of condensation is when you hear water drips. This could be because of a damaged seal between the two glass panes. Repairs are highly recommended if you hear this sound. This will stop cold drafts entering your home. This kind of issue could also lead to mold in the long run, so it is best to get the window fixed as soon as possible.

Having a professional inspect your Window Doctor for condensation is the most effective way of dealing with this issue, as they can determine the best course of action. Most professional companies will remove the affected pane and then pipe hot air into the space between them, this will dry out any moisture that remains and ensure that a high-quality seal is reapplied.

Double condensation on glazing is caused by defective windowpane seals. When the window seal fails, it allows cool air into double-paned windows, which makes them to fog. If this occurs, it is possible that simple fixes could aid, but in most cases, the best solution is to replace the window.

The majority of double-glazed windows feature an "espacer" bar that is placed between the two glass panes. This spacer bar contains desiccant, which absorbs any moisture and blocks it from reaching the glass. This bar is susceptible to breaking or cracking, and in most cases, you'll need to replace the entire window.

It is possible to do repairs yourself if you have the right tools, however it is usually better to hire an experienced professional to carry out this for you. This will not only save you a great deal of time, but it will also ensure that your double glazing is repaired correctly and of the highest possible quality. Employing a reputable tradesperson could also mean you receive some form of guarantee for the work done that you would not get from DIY jobs.

Shattering

Double glazing is a wonderful invention that allows homeowners to save money on heating bills while keeping their homes warm and comfortable. However, it's not indestructible and occasionally problems can occur. These issues can be dangerous in certain instances if they're not addressed quickly.

If you spot any issues in your double-glazing that could put your family in danger, it's important to address them as quickly as you can. Issues like misting and water leaks can compromise the performance of windows and make them look unsightly.

Repairing double-glazed windows can be cheaper than replacing them. So, if you've noticed any indications of issues with your double glazing, you should consider researching local companies that specialise in the repair of double-glazed windows and getting quotes. Remember that the cheapest quote isn't always the best choice and make sure that the firm offers a guarantee on their work.

If a double-glazed window is sold, it will be contained inside an Insulated Glass Unit (IGU). The Insulated Glass Unit (IGU) is made up of two glass panes with a space in between, and a rubber gasket which prevents water from leaking into the gap. Some IGUs also contain a gas such as Argon that helps to prevent heat from leaving your home, thus cutting down on energy costs.

If one of the IGU panes is damaged, it is possible to purchase a replacement from a window manufacturer, and then installed on the frame. This is usually less expensive than replacing the whole window replacement and is much more cost-effective for most households.

Depending on the kind of window you have and the condition of the frame, it might be possible to repair the damaged pane. This is typically the case when it has only developed a few tiny cracks, but has not broken. If the double-glazed window is completely shattered then it is recommended to replace both the glass unit and the window sash.
