How to Repair Double Glazed Windows
Double glazing that is noisy or difficult to open or has sagged, fallen or sagged could require repair. Qualified tradesmen can fix or replace hinges mechanisms handles, seals, and handles.
It is possible to make some repairs yourself but it is often more time consuming than having a professional complete it for you. It is also more secure.
1. Broken Panes
Double pane windows utilize the space between the two panes in order to create an airtight seal. This allows the heat inside and the cold out. 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 double pane windows cracks as soon as they begin to appear. A small crack could worsen over time and result in a broken window.
If you've broken a pane, it's recommended to call in a professional. They'll locate a replacement that is compatible with your frame. After that, they'll install the new pane and make sure it is secure. It is also essential to take out the old putty and glazing points before putting in a new window.
Wearing gloves and eye protection is recommended for this job. Utilize a pull-type paint scraper or an old chisel to pry out the old putty. You can use a heat gun to soften the putty and stop it from breaking. Once all the putty is removed, you'll have to clean and sand the areas where the glass is going to go. You can then apply silicone caulk for extra durability.
You can order a brand new window pane from your local hardware store or home improvement store. Measure the width and height to determine the size window you require for your home. Subtract 1/8 inch on all sides to get the exact measurements needed for a replacement. Otherwise, you may end having windows that don't fit properly and leave your home vulnerable to the elements.
2. Condensation
Many double glazing owners will encounter condensation at some point during the lifespan of their windows. It is typically caused by the absence of air circulation or humidity issues which cause cold surfaces such as windows to draw moisture. This is particularly problematic in bathrooms, where steam can flow through the window, and cool to form condensation.
Because this moisture gets trapped in the space between the panes of glass this can cause heat to be lost from your home or building and result in higher energy costs for you. If the condensation is left untreated, it could lead to mould and damp in your home.
Open your windows every day in the morning, unless it is extremely cold. and ensure that you keep the vents for trickle vents open when you leave. You can also use dehumidifiers in your home to help absorb water and prevent it becoming a problem for surfaces like your double-glazing.
In more serious cases, you may have to replace the windows that are double-glazed completely if there's cracks in the seal between the panes. This will be expensive repair, but, it will help to keep your home or building warmer and more energy efficient. Make sure that your double-glazed unit is still covered under warranty. If so, the installers will replace the windows for free. Avoid DIY solutions for condensation since this could invalidate your warranty.
3. Leaks
If you see water droplets or a mist between your double glazing panes this could be an indication that the seals are faulty. This does not necessarily mean you need to replace the window. It can be fixed by replacing the caulking.
The frames of double-glazed windows and doors expand and contract as a result of temperature variations. This can result in gaps appearing in the frame, which can eventually let water into the home.
Another reason is that, over time, the insulating gas within the window can become dislodged, and this could result in an air draught, and let moisture in the home. If you notice that your double-glazed windows are becoming difficult to shut or open, then wiping them with cold water can temporarily solve the issue until warm weather returns.
Most double glazed windows and doors are covered under a warranty from the company who installed them. If you have any problems with double glazing that are covered by this guarantee, get in touch with them as soon a possible. It is best to do this via phone or in person, and then followed up by an email describing the problem and the date at which it was first noticed. This will help avoid confusion later on if there is a dispute regarding what is or isn't covered under your guarantee. It will also ensure that your complaint is taken seriously by the business that performed the work. If you are unable to get a satisfactory response from the company you bought the double glazing from, it might be worth seeking the services of an alternative tradesman who is approved by Checkatrade and is rated by their customers.
4. Hardware Damaged
A double glazed window comprises two glass panes that are separated by spacer bars, with an opening filled with gas for insulation. It is set in frames constructed of aluminium or uPVC. Over time, the hardware can be loose, and a window or door that won't open can be a hassle.
If a double glazing window is damaged, the cost of replacing it can add up. Window repair companies charge between $50 and $80 an hour to take out and replace the old window. The price is based on the size, thickness, and shape of the window as well as quality and design of the frame and sash. The price will also be affected by the type of window used, double or single hung or sliding. Repairing windows that are higher or require roof access could be more expensive as the technician will require extra safety measures and tools.
When a double-glazed window is repaired the installer will clean the surface of the new pane prior to sealing it. They will then apply a bead of silicone around the edges to ensure the seal is watertight. This is crucial for windows that are located on the ground level of a building, where condensation can accumulate in the bottom frame.
Another method to keep your windows looking great is to paint them regularly using the highest quality paint. This will help protect windows from fading caused by UV radiation and will keep them looking fresh and shiny for longer. Double glazed windows will also make your home quieter and boost its value on the market by making it more energy efficient and comfortable for potential buyers to reside in.
5. Glass that is damaged
Double-glazed windows are intended to insulate your home by keeping cold air out and letting warm air into. This helps reduce the amount of sunlight that gets into a room and also protects furniture from damage caused by sunlight. But sometimes, glass can get broken. Perhaps a pebble bounces off a lawnmower or a strimmer and cracks the pane. Or maybe a kid throws a ball at it or a collision occurs. Whatever the cause the window that is broken can be an inconvenience.
Most often, a damaged or cracked pane can be repaired using epoxy or another similar product. Before applying the epoxy, it is necessary to clean and get rid of the old putty. You can soften the putty by using a cotton soaked in linseed or a heat gun. Then you can scrape off the glass that has split and scrape the edges to eliminate any traces of old putty from the frame.
Apply the epoxy on the crack and spread it across the entire surface. It is essential to press it firmly into the crack. Allow the epoxy to dry completely before you put in the new pane. Make sure that the replacement is of the same size to the original. If you are replacing glass with leaded, gently bend the lead in an H shape back over it.
