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 may be wondering if they could be repaired.
You might be able to get your double glazing covered under warranty, based on the issue and when you bought it.
Broken Panes
If a window's glass is damaged or cracked, air can pass through more easily. This decreases the effectiveness of the window as an insulation and protects against the elements. Based on the season it can allow cold or hot air to flow into or out of your home, which can increase the cost of cooling and heating.
If window repairs in the double glazing isn't very deep, it may be possible to apply a strong-hold tape. This is temporary fix, and will be able to prevent the crack from getting more severe. A professional window repair service can repair any broken glass on double-glazed windows.
Removing a damaged window pane yourself can be difficult and risky. If the crack is substantial and difficult to remove, you can try applying strips of masking tap in a crisscrossing design. If the crack isn't too large you can employ a slicing tool to remove the glass from the frame. Wear gloves and a mask when cutting the glass. Once the pane is free it is necessary to place it flat on several layers of newspaper to stop any pieces that might fall.
To install a replacement glass you'll need to prepare the frame and purchase replacement glass. To ensure that your new pane is properly fitted take a measurement of the opening of the window frame and subtract between 1/16 and 1/8 inches on both sides. Then, you can have your replacement glass cut according to this measurement at your local glass shop or at a hardware store. If you have wooden frames, purchase points for glaziers from a local hardware shop to install on the outside of your new pane. Be sure to position the points in a manner that allows for expansion and contraction while still keeping the putty in a flat position against the glass.
Spread a thick layer of it with the blade of a putty maker after your new pane is installed. You can use a linseed oil-based putty such as Sarco or a less expensive product like Dap glazing compound. If you have any gaps between your new pane and the frame you can fill them in with the compound you choose. Smooth the compound on your new pane to make sure it is level and even.
Water Leaks
The appearance of water leaks around the frame or sash is a frequent issue that happens when the window sealant has degraded and needs to be replaced. Water leaks can damage the drywall and plaster surrounding the window, and can cause damp or spongy walls that require to be restored as quickly as is feasible.
A double-glazed window of high quality has a gasket that compresses firmly when the sash is closed. Any water that hits this area should be drained out through the weep holes in the bottom of the frame. However, sometimes the weep holes get blocked by a build-up of dirt and debris, or the weather stripping around the window may need to be replaced.
Another potential culprit of water leaks is the lintel which holds the bricks over the window. The installers who built the house may not have realized that the lintel needs to be allowed to drain properly or they could have just covered it with concrete, leaving gaps that allow rainwater to enter and pool around the window causing dampness in the wall or wood rot. The builders should have angled the fascia boards above the window to ensure that water is directed properly and this will stop water from entering the building through these gaps.
Another potential source of leaks is the gap that exists between the glass panes in the double-glazed unit. A damaged seal could have caused argon gas or krypton that is supposed to be in between the glass panes to provide insulation to leak. Although this isn't the most serious issue with leaky windows but it could affect energy efficiency. It should be addressed in the shortest time possible. In this instance double glazing replacement might be required. A professional can perform an exhaustive assessment and identify the cause of the leak. They will also recommend solutions. They will also be able advise whether it is advisable to repair the window or replace it completely. They will also provide an estimate for any work required.
Condensation
Condensation is quite a common issue in older double-glazed windows and doors, but it is usually easily solved. It is caused by an absence of air circulation around the windows. It is common in rooms like kitchens or bathrooms. Droplets of water on the surface of the glass are an obvious sign of condensation. These droplets will quickly disappear when the window is heated by sunlight. If the problem persists it's worth investigating further.
Another indication of condensation is if you hear water drips. This is most likely because of a damaged seal between the two glass panes. Repairs are highly recommended if you notice this sound. This will prevent cold drafts from entering your home. This kind of issue could cause mold in the long run, so it is best to have the window repaired as soon as you can.
A professional inspection of your window for condensation is the most effective approach to tackling this issue, as they can suggest the best course of action. The majority of professional companies will take off the affected pane, and then pipe hot air into the space between the two. This will eliminate any moisture that remains and ensure a good seal is put back on.
The windowpane seals failing are the main reason for condensation problems with double glazing. Cool air gets into double-paned windows when the window seal is damaged and causes them to get clogged. If this occurs it's possible that simple fixes will aid, but in most cases the best solution 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. This spacer bar is filled with desiccant that absorbs any moisture that might be present, thereby keeping it out of the glass panes and causing condensation. This spacer bar is prone to breaking or cracking and it's usually necessary to replace your entire window.
It is possible to do some repairs yourself if you have the appropriate tools, however it is usually better to hire an expert who is trained to do this for you. This will not only save you a great amount of time, but it will also ensure that your double glazing is repaired correctly and with the best quality possible. Using a trusted tradesman can also mean that you get some kind of assurance for the work carried out that you can't get from DIY jobs.
Shattering
Double glazing is a fantastic technology that lets homeowners save money on heating costs, while keeping their homes warm and comfortable. It isn't impervious to damage and problems can arise occasionally. These faults can be dangerous in some instances if they are not corrected quickly.
If you have noticed any problems with your double glazing that could put your family at risk it is essential to have them fixed as soon as you can. Faults like misting and leaks of water can affect the effectiveness of windows and cause them to look unsightly.
Repairing double-glazed windows is usually cheaper than replacing them. If you've noticed any signs of issues with your double glazing, it's worth looking for local companies that specialize in the repair of double glazed windows and asking for estimates. The most affordable quote might not be the best option. Be sure that the company you choose to work with offers an assurance on their work.
Double-glazed windows are sold in an Insulated Glass unit (IGU). The Insulated Glass Unit (IGU) is composed of two glass panes with an area between them, and a rubber gasket which stops water from entering the gap. Certain IGUs also contain a gas like argon that helps to keep heat from getting out of your home, thereby cutting down on energy costs.
If one of the IGUs is damaged, a replacement pane can be purchased from a window manufacturer and then fitted to the frame. This is usually cheaper than replacing the entire window and is cost-effective for many households.
It could be possible to repair the damaged glass depending on the frame type and condition of your window. If the glass has developed only a few tiny chips, but has not shattered, this is usually the situation. If the double-glazed windows are completely shattered then it is recommended to replace both the glass unit as well as the window sash.
