How to Repair Double Glazed Windows Double-glazed windows are often covered by warranties that last for 10 or 20 years. Make sure to verify the warranty. Repairing double glazing is cheaper than replacing it and can save you money and energy. It is possible that the sealant between your glass panes has failed if you have misted double glazing. This is usually the case when windows are old or worn and can be costly to replace. 1. Cracked or chipped glass A cracked or chipped double-glazed window is a common issue that can lead to condensation between the two glass panes in your home. In the majority of cases replacing the glass unit is necessary, especially in the event that one or both panes have been damaged. If the frame is in good condition, then repair of only one glass pane could be an alternative. Masking tape or duct tape are quick and simple ways to seal the cracks. One strip of tape ought to suffice to seal superficial cracks like stress fractures caused by temperature variations. For deeper cracks, such as those caused by impact, it's recommended that the tape be stretched over the entire length the crack to ensure it will keep the glass in place. Another option for permanent solutions is to utilize a solvent-based adhesive. This is usually applied to both the inner and outer surfaces and then spread using the help of a putty knife. This method can be more time-consuming than using masking tape, however, it is more effective in preventing the cracks from spreading. If the cracks are severe or have occurred over several years it is recommended to wait to hire a professional to repair your windows. This will result in a stronger finish. If the cracks aren't too bad and they aren't creating any leaks in the water or leaks, it's best to continue with the quick fixes since they can help keep repair costs low. Applying a two-part epoxy to the crack will make it stronger and more permanent. The glass surface must be cleaned with a damp cloth, and then allowed to dry completely. Mix the resin and hardener according to the directions on the package and then apply it to the crack using a putty blade. After it has dried completely you can paint over the putty as well as the surrounding frame to create a seamless finish. 2. Water Leaks If your double-glazed windows have been getting leaky or you've noticed condensation in between the glass panes, both problems can be fixed without having to replace your windows. This is because the problem is not with the uPVC, aluminium or timber window frames but in the IGU, or insulated glass unit (IGU) that is situated between them. The IGU is made up of two sheets of glass that are separated by a bar that acts as a spacer and then filled with an insulating gas similar to a glass sandwich. Ideally, the gap is airtight, and this is what helps to keep cold air from your home, energy from heating and your home warm. The seals of the IGU are susceptible to weakening over time, and at different temperatures. Water leaks are easily identified by a couple of indicators including water on the window sill and frame, discolouration and a musty smell. If you spot any of these, you need to get in touch with an expert immediately for repairs. If you have condensation on the outside of your double-glazed windows, it's probably due to the high levels of humidity in your home.

However, if you have moisture in between the panes of glass in your double-glazed windows this indicates that the IGU has failed and is not performing as it should. The presence of moisture between the glass panes isn't just unattractive, it also affects the efficiency of your double glazing as it no longer keeps the cold out and the heat in. There are several ways this issue can be solved, but it's usually best to leave it to the experts. They will drill small holes into the affected pane of the glass insulated unit. They then pump in or inject desiccant to eliminate all of the moisture and then use a special anti-fogging solution to prevent the condensation from returning. They can then blow hot air through the gap to dry it further. 3. Draughts Double-glazed windows are fitted with an airtight seal in order to stop condensation from forming between the panes. However the seal may be damaged as time passes. When this happens, you may detect a cold draft coming in through the window or door. This can be very annoying and can cause an increase in energy efficiency. If your windows are draughty, it is recommended to contact a repair service immediately to repair the seal. Double glazing is a type of window that includes two glass panes within a frame composed of aluminium or uPVC. The main part of double-glazed windows is an Insulated glass panel (IGU) that is made up of two sheets separated by an air gap that is filled with insulating gases.

Utilize a dehumidifier for this problem or a packet desiccant. However, if you're dealing with a serious problem or a long-term issue, it may be recommended to contact experts. Despite being extremely sturdy frames made of uPVC can weaken over time, particularly in the case of an extremely cold or warm day. This is not unusual, but it can cause problems like a stuck or stiff window. Engaging a UPVC specialist is typically the best way to address these issues. Some businesses will drill a hole in the window and put in desiccants to draw out any moisture. This is an excellent solution and is less expensive than replacing the window. However, it's important to keep in mind that the hole needs to be repaired after six months, and moisture could return when there's a crack in the seal somewhere else in the window.
