Can Double Glazed Windows Be Repaired?

If you have recently had double glazing installed in your home and they are beginning to show signs of failing you might be wondering if they can be fixed.

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

Broken Panes

If a window's pane is cracked or broken air can enter more easily. This decreases the effectiveness of the window as an insulation barrier and also against the elements. Depending on the time of year it can allow cold or hot air to flow into or out of your home, causing an increase in heating and cooling costs.

If the crack isn't too deep, you might be able to use a strong-hold adhesive tape. This is temporary fix and could just stop the crack from getting more severe. To ensure the best results, a reputable window repair company should be contacted to fix any broken glass on your double-glazed windows.

It can be dangerous and difficult to repair a window pane on your own. If the crack is too big to grasp, try pressing strips of masking tape in a crisscrossing pattern prior to trying to remove it. If the crack isn't too large, you can employ a slicing tool to cut the glass away from the frame. Be sure to wear gloves and a mask when cutting glass. After removing the glass and laid flat, you can place it on several layers of newspapers to catch any pieces that might fall.

To install a new pane you will need to purchase replacement glass and prepare the frame. Take measurements of the opening of the frame and subtract 1/16 - 1/8 inch in both directions to make sure that the new pane will fit properly. Have your replacement glass cut at a local hardware or glass shop to this measurement. If you have wooden frames, you can purchase glaziers points from a hardware shop to install on the edges of your new pane. Be sure to position the points in a manner that will allow expansion and contraction while keeping the putty level against the glass.

Spread a thick layer with a putty blade once the new pane has been installed. You can use a linseed oil-based putting such as Sarco, or a cheaper product such as Dap glazing compound. If you notice any gaps between your new pane and the frame you can fill them in with the chosen compound. Make sure you smooth the compound so that it is level and even around the pane.

Water Leaks

The occurrence of water leaks around the frame or sash is a frequent issue that happens when window sealant has become degraded and needs to be replaced. Water leaks around the window could damage the drywall or plaster and can cause damp walls.

A good double glazed window will have a gasket that firmly compresses when the sash is closed. The water that enters the area should be drained out through the weepholes of the frame. However, in some cases, the weep holes become blocked by a build-up debris and dirt or the weather stripping around the window could require replacement.

Another potential culprit of water leaks is the lintel which holds the bricks above the window. The people who built the house may not have understood that the lintel needs to be let to drain properly or they may have simply covered it with concrete, leaving an opening where rainwater could enter and pool around the window, creating dampness in the wall or wood rot. The builders should have bent the fascia boards over the window to ensure that water is directed correctly and this will stop water from getting into the structure through these gaps.

Another source of leaks is the gap between the glass panes in the double-glazed unit. A damaged seal could have caused the gas argon or krypton that is supposed to be between the glass panes to provide insulation to leak. Although this is not the most serious problem with leaky windows, it will have a negative impact on energy efficiency. It is important to address the issue as quickly as possible. In this case replacement double glazing might be the best option. A professional can complete an extensive evaluation, let you know where the leak is coming from and recommend solutions. They'll also be able advise whether it is appropriate to repair the window or replace it completely. They will be able to also give you a quote for any work required.

Condensation

Condensation is quite a common issue in older double-glazed windows and doors, but it can be easily fixed. This is due to a lack air flow around windows and is common in kitchens and bathrooms. Water droplets on the surface of the glass are a clear indication of condensation. These droplets will evaporate quickly when the window is heated by sunlight. If the issue persists, it is worth looking further.

There is also the sound of the sound of water drip. This is likely due to a broken seal between the two glass panes. Repairs are highly recommended if you hear this noise. This will stop cold drafts entering your home. This kind of issue could cause mould in the long term It is therefore recommended to have the window repaired when you can.

Having a professional examine your window for condensation is the best method of tackling this issue, as they can suggest the best procedure to take. Most professional companies will remove the affected window and pipe hot air into the space between the two, this will evaporate any moisture that remains and ensure a quality seal is reapplied.

Windowpane seals that fail are the primary cause of condensation problems with double glazing. When the window seal fails, it allows cool air to get into double-paned windows, which makes them fog. If this occurs, it is possible that simple fixes could aid, but in most instances, the best option is to replace the window.

Most double glazed windows have spacer bars that sit between the two panes of glass. This spacer bar contains desiccant that absorbs any moisture and blocks it from getting into the glass. Unfortunately, this bar can sometimes break or crack and in this situation, it is usually required to replace the entire window.

You can repair some of the issues yourself using the correct tools. However, it is more common to hire a professional who has been trained to do this. You will save a lot of time and ensure that the double-glazing is repaired correctly. A reliable tradesman will offer a guarantee on the work they have done that you wouldn't get if you were to do it yourself.

Shattering

Double glazing is a fantastic innovation that allows homeowners to save money on heating bills, whilst keeping their homes warm and comfortable. However, it isn't indestructible and occasionally issues can arise. In certain instances, these faults may even be dangerous if not dealt with quickly enough.

If you have noticed any problems with your double glazing that could be putting your family members in danger, then it's important to fix them in the earliest time possible. Faults like misting and water leaks can compromise the efficiency of windows and cause them to look ugly.

Repairing double-glazed windows is typically more cost-effective than replacing them. If you see any indications of problems with your double glazing it is worth researching local companies who specialize in double glazed window repairs and getting quotes. The most affordable quote might not be the best choice. Make sure that the company you choose to work with offers a guarantee with their work.

When a double-glazed window is sold, it will be contained within an Insulated Glass Unit (IGU). It is made up of two glass panes, a space between them and the rubber seal that stops water from seeping into the insulating gap. Certain IGUs contain Argon, a gas that stops heat from escaping the house and helps save money on energy costs.

If one of the IGU panes is damaged, then you can purchase a replacement from a window manufacturer, and then fitted to the frame. This is normally far cheaper than replacing the whole window and is far cheaper for most households.

It could be possible to repair the damaged glass dependent on the type of frame and the condition of the window. If the glass has formed only a few tiny chips, but not been damaged, this is typically the situation. If the double-glazed windows are totally broken, it's recommended to replace both the glass unit as well as the window sash.
