1. Broken Panes
Double pane windows utilize the space between the two panes in order to create an airtight seal. This helps keep warmth inside and cold outside. This seal can be compromised when it is exposed to extreme temperatures or a physical impact. This is why it's so important to repair cracks in double pane windows as soon as they appear. A small crack could worsen over time and lead to a broken window.
If you've got a damaged pane, it's best to get in touch with an expert. They'll be able to find a replacement window that fits your frame. Then, they'll put in the new pane and ensure it's secure. Before installing a new window, it is important to take off any old putty or metal glazing points.
Wearing eye protection and gloves is recommended for this task. Make use of a paint scraper that is a pull type or an old chisel to break out the old putty. You can use a heating gun to soften the putty and prevent it from cracking. Once all the putty is removed, you'll have to clean and sand the grooves where glass will be placed. Then, you can apply silicone caulk for durability.
It is best to purchase windows with a new pane of glass from your local home improvement or hardware store. Measure the width and height to determine what size window you need for your home. Make sure you subtract 1/8 inch from all sides, so you can get the exact measurements required to make a replacement window. Otherwise, you could end with a window that doesn't fit properly and leave your home vulnerable to the elements.
2. Condensation
Condensation is a common issue that a lot of double glazing owners will face at some point during their windows' lifespan. Most often, it is caused by a lack of air circulation in rooms, or humidity issues which cause windows with cold surfaces to draw moisture from warm air. This is particularly a problem in bathrooms, as excessive steam will flow through the window and cool down to form condensation on the glass's surface.
The moisture in the air can cause heat loss from your home, which could increase your energy costs. If the condensation is left untreated, it can cause mould and damp in your home.
The most effective method to stop condensation is to open your windows every morning (unless it's extremely cold!) and ensure that you have the trickle vents in place when you go out. You can also install dehumidifiers at home to help absorb water and stop it from becoming a problem for surfaces like your double-glazing.
In more serious instances, you may have to replace your double glazed windows completely in the event that the seal between the two panes has broken. This can be expensive, but it will help keep your home or building warmer and more efficient. Verify that your double glazing is still covered by the warranty. If so, the installers will replace the window units at no cost. Avoid attempting DIY solutions for condensation since this could be a violation of your warranty.
3. Leaks
If you see water droplets or a mist appear between your double glazing panes, it could be a sign that the seals are faulty. This doesn't necessarily mean you need to replace the window. It is fixable by replacing the caulking.
The frames of double-glazed windows and doors expand and contract as a result of temperature fluctuations. This can result in gaps forming around the frame that eventually create drafts and allow water to enter the house.
Another reason could be that the insulating gases within the window become dislodged with time. This could create a draft and let moisture into the home. If your double-glazed windows are a challenge to close and open Wiping them clean with cold water may temporarily resolve the issue until the weather warms.
In the majority of instances, double-glazed doors and windows be covered by a warranty from the company who installed them. If you're having issues with your double glazing that fall under this guarantee, then ensure that you contact them as soon as you can. It is best handled by phone or in person. It should be followed up with an email stating the problem and when you first noticed them. This will avoid confusion in the future, if there is a dispute over what was or wasn't covered under your warranty. It will also ensure that your complaint is taken seriously by the company who carried out the work. If you're unable get a satisfactory response from the company you bought your double glazing from then it may be worth seeking the services of another tradesman who is endorsed by Checkatrade and is rated by their clients.
4. Hardware damaged
A double-glazed window consists of two glass panes, separated by spacer bars, and a gap that is filled with an insulating gas. It is set in a frame of aluminum, uPVC or wood. Over time the hardware may become loose and a window or door that won't open can be annoying.
If a double-glazed window is damaged, the cost of replacing it could increase. Window repair companies charge between $50 and $80 an hour to take out and replace the old window. RepairMyWindowsAndDoors is based on the size the window, its thickness, and the shape of the window, as well as the quality and design of the frame and sash. The cost of repair will also be based on whether the window is single-hung or double-hung. Windows that are larger or require access to the roof will cost more to repair as the repair technician needs extra tools and safety measures.
When a double-glazed window is repaired the installer will clean the surface of the new window before sealing it. They will then apply a bead of silicone around the edges to ensure the seal is watertight. This is crucial for windows on the ground of a building where condensation may build up in the bottom frame.
Another way to ensure your windows look nice is to paint them regularly using an excellent paint. This will prevent them from fade due to UV radiation and will keep them looking fresh and shiny for a longer period of time. Double-glazed windows also make your home more peaceful and increase its value by making it more energy-efficient and comfortable for potential home buyers to live in.
5. Glass damaged
A double glazed window is intended to create a barrier to heat for your home and keep cold air out and warm air in. This decreases the amount of sunlight that comes into a room and protects your furniture from sun damage. But sometimes, glass can get broken. A pebble might bounce off a lawnmower or strimmer and cracks a pane. A child might throw a ball at it or a mishap could happen. A damaged window can be an inconvenience.
A cracked or damaged pane can be repaired using epoxy or similar products. It is essential to clean the area and eliminate any old putty that is surrounding it prior to applying the new epoxy. You can do this using a cotton rag soaked in linseed oil, or you can use the heat gun to soften and loosen the putty. Then, scrape off the pieces of glass that have split and chisel along the edges to remove the old putty.
Then, apply the epoxy to the crack, spreading it over the entire surface. Press it down firmly, pressing it into the crack. Let the epoxy dry completely before you put in the new pane. Make sure the replacement is of the same size to the previous one. If you are replacing a lead glass panel, gently bend the H-shaped lead back over it.
