Can Double Glazed Windows Be Repaired?

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

You might be able to get your double glazing repaired under warranty depending on the problem and when you bought it.

Broken Panes

If a window's glass is damaged or cracked it allows air pass more easily, lowering the effectiveness of windows as insulation and barrier against the elements. This can allow hot or cold air to enter your home, based on the season. Heating and cooling costs will increase.

If the crack is not too deep, you may be able to use an adhesive tape with strong-hold. This is a temporary fix, and may only stop the crack from getting more severe. To get the most effective results, a professional window repair service is required to fix any damaged glass in double-glazed windows.

It could be risky and difficult to replace a window doctor pane on your own. If the crack is too big to grasp and hold, try putting strips of masking tape across it in a crisscross pattern before trying to take it off. If the crack isn't too large, you can make use of a razor to remove the glass from the frame. Be sure to wear gloves and a face mask when cutting glass. After the glass has been removed, place it flat onto several layers of newspaper to catch any pieces that may fall.

To install a replacement pane you'll need to prepare the frame and purchase replacement glass. To ensure that your new glass is a good fit you must measure the opening of the frame and subtract between 1/16 and 1/8 inches on both sides. Then have your replacement glass cut according to this measurement at a local glass shop or hardware store. If you have wooden frames, you can purchase points for glaziers from a hardware store to place them on the edges of your new pane. Be sure to position the points in a way that will allow expansion and contraction while still keeping the putty level against the glass.

Spread a thick layer with a putty blade once your new pane is installed. You can use a linseed oil-based putting like Sarco or a less expensive product like Dap glazing compound. Fill any gaps that exist between the new pane and frame using the compound you choose. Smooth the compound around the new pane to ensure it is level and even.

Water Leaks

Water leaks in a window's frame or sash can be a frequent issue. This happens when the window sealant is worn out and needs to be replaced. Water leaks around windows can cause damage to the plaster or drywall and cause damp walls.

A good double glazed window will come with a gasket which firmly compresses when the sash is shut. Water that falls on the area should be drained out through the weepholes in the frame. Sometimes, however, the weep holes become blocked by a build-up of dirt and debris, or the weather stripping around the window might require replacement.

The lintel above the window could also be a source of leaks. Installers who built the house may not have been aware of the importance of allowing the lintel drain properly, or have covered it in concrete, which left a gap in which rainwater can enter and get trapped, and cause dampness or rot to the wood. The installers should have bent the fascia boards over the window to ensure that water is directed correctly and this will prevent water from entering the building through these gaps.

Another potential source of leaks is the gap that exists between the glass panes of the double-glazed unit. A worn seal could have caused gas argon or krypton which is supposed to be in between the glass panes to provide insulation to leak. While this isn't the most serious issue associated with windows that leak however, it could affect energy efficiency. It is important to address the issue as quickly as possible. In this situation, replacement double glazing may be a good idea. A professional can complete an extensive evaluation, let you know the source of the leak from and suggest solutions. They will also be able advise whether it is appropriate to fix the window or replace it completely. They can also provide an estimate for any work needed.

Condensation

Condensation can be a problem with older double-glazed windows and doors. However, it's generally an easy solution. It is caused by the lack of air flow around the window, and typically happens in rooms such as bathrooms or kitchens. The most obvious sign of condensation is droplets of water appearing on the glass surface. These droplets will disappear quickly when the window is heated by sunlight. However, if the issue persists it is worth investigating further.

You can also hear the sound of water drip. This is usually caused by a leak in the seal between the two glass panes. If you hear this sound, then a repair is highly recommended since it will stop cold drafts from entering your home. This type of problem may also lead to mould over time, so it's recommended to have the window repaired as soon as you can.

Having a professional inspect your window for condensation is the best way of dealing with this issue, since they will be able to suggest the best procedure to take. Professional firms will take off the glass that is affected and blow hot air between the two panes. This will eliminate any moisture that remains and ensure that a good seal is applied.

The windowpane seals failing are the main cause of condensation issues with double glazing. Cool air enters double-paned windows when the window seal fails and they begin to get clogged. If this happens it's possible that simple fixes will assist, but in many instances, the best option is to replace the window.

A spacer bar can be located between the two glass panes that are found in the majority of double-glazed windows. The spacer bar is filled with desiccant, which absorbs any moisture that may occur, therefore stopping it from getting to the glass panes and causing condensation. However, this spacer bar can break or crack, and in this case it is usually necessary to replace the entire window.

You can make some repairs yourself using the appropriate tools. However, it is usually better to hire someone who has been trained to do this. This will not only save you a huge amount of time, but it will also ensure that your double glazing is repaired properly and of the highest quality. A reliable tradesman will provide you with a warranty for the work completed that you could not receive if you tried to repair it yourself.

Shattering

Double glazing is a fantastic technology that lets homeowners save money on heating costs, while keeping their homes warm and comfortable. It's not impervious to damage and problems can arise occasionally. In certain instances, these faults may even be dangerous if not addressed quickly enough.

If you spot any issues with your double-glazing, which could put your family members in danger, it is important to address them as quickly as possible. Issues such as misting or water leaks can damage the performance of windows and cause them to look ugly.

It is often far more cost effective to repair your double glazed windows than it would be to replace them completely. If you've noticed any signs of problems with your double glazing, consider searching for local companies that specialize in the repair of double-glazed windows and asking for estimates. Remember that the cheapest quote isn't always the best option and ensure that your chosen company offers a warranty with their work.

If a double-glazed window is sold in the market, it will be housed within an Insulated Glass Unit (IGU). It is made up of the two glass panes, a gap between them, and an insulating rubber seal that prevents water from getting into the insulating 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 IGUs is damaged a replacement pane can be purchased from a window maker and then fitted to the frame. This is typically less expensive than replacing the entire window and is more cost-effective for many households.

It is possible to repair the damaged glass depending on the type of frame and the condition of the window. This is typically the case if it has only developed a few small cracks, but is not shattered. If your double glazed window has completely broken and is cracked, then it's best to replace the entire glass unit as well as window sash.
