It is possible to make some repairs yourself, however it can be time-consuming than hiring a professional to do it for you. It is also safer.

1. Broken Panes

Double pane windows depend on the space between them to form an airtight seal. This keeps warm air inside and the cold outside. However, this seal can be damaged by physical impact or exposure to extreme temperatures. It is essential to fix cracks in double pane windows when they first begin to appear. A small crack may worsen over time and lead to a broken window.

It is recommended to speak with an expert if you have broken windows. They'll locate a replacement that fits your frame. They'll then put in the new window and make sure that it's secure. Before installing a new window it's essential to get rid of any old metal or putty glazing points.

This is a challenging task, so it's best to wear gloves and eye protection. Make use of a paint scraper that is a pull type or an old chisel to pry out the old putty. To ensure that the putty doesn't crack, you can hold a hot gun on it to slowly soften it. After the putty is removed, you will need to clean the grooves and sand them. Then, you can apply silicone caulk for extra durability.


It's best to order a new pane of window glass from your local home improvement or hardware store. Take measurements of the width and height to determine what size window you will need for your home. Make sure to subtract 1/8 inch from all sides so that you will have the exact measurements required to make the replacement window. Otherwise,  double glaziers near me  could end with windows that don't fit properly and leave your home vulnerable to the elements.

2. Condensation

Condensation is a frequent issue that a majority of double glazing owners will encounter at some point during their windows' life span. It is usually caused by an absence of air circulation in rooms, or humidity issues, which causes windows that are cold to draw moisture from warm air. This is a particular problem in bathrooms where excessive steam can travel through the window, and cool to form condensation.

This moisture could cause heat loss from your home, which can increase your energy costs. If this condensation is left untreated, it can lead to mould and damp in your home.

The most effective way to stop condensation is to open your windows every morning (unless it's extremely cold!) and ensure that you keep the vents for trickle vents open when you go out. You can also install a dehumidifier at home to help soak up excess water and prevent it from developing on cold surfaces, including your double-glazing.

In more serious cases, you may need to replace your double glazed windows completely if the seal between the two panes has been damaged. This is expensive repair, but it will keep your home or building warmer and more efficient. Verify that your double glazing is still covered under warranty. If it is, the installers will replace the window units at no cost. Do not attempt DIY fixes for condensation because this could cause damage to your warranty.

3. Leaks

If you notice drops of water or a mist between your double glazing panes, it could be a sign that the seals are not working correctly. But, this doesn't suggest that you require a new window since it is often repaired by simply replacing the caulking around the frame.

The main cause of this problem is due to the varying temperatures that cause the frames of double-glazed windows and doors to expand and shrink. This can result in gaps in the frame, which will eventually allow water into the home.

Another reason is that over time, the insulating gas within the window may become dislodged, and this could result in a draft and allow moisture to enter the home. If your double-glazed windows are a challenge to open and close, wiping them down with cold water will temporarily solve the problem until the weather warms.

Most double glazed doors and windows are covered by a warranty from the company that installed them. If you experience any issues with double glazing that are covered by this guarantee, contact them as soon as you can. It is best to do this by phone or in-person, and then followed by an email describing the issue and when it was first noticed. This will prevent confusion in the event that there is a dispute over what is covered or not covered under your warranty. It will also ensure that your complaint is considered seriously by the company that carried out the work. If you're unable to get a satisfactory response from the business you bought the double glazing from, then you might consider hiring an alternative tradesman that is endorsed by Checkatrade and is rated by their customers.

4. Hardware damaged

Double-glazed windows comprise two glass panes, separated by spacer bars and an opening filled with insulating gas. It is encased in a frame made of uPVC, aluminium or wood. Over time, the hardware can be loose, and a door or window that isn't able to open can be annoying.

The cost of replacing a double-glazed window could be high. Window repair companies charge between $50 and $80 per hour to remove the window that was broken and replace it with a brand new one. The exact price will depend on the size, shape and thickness of the window as well as the design and quality of the surrounding frame and sash. The cost of repair will also be based on whether the window is single-hung or double-hung. Repairing windows that are larger or require roof access can be more expensive because the technician will require extra safety precautions and tools.

Installers will clean the new pane of a double-glazed window before sealing it. They will then apply a bead of silicone around the edges to ensure the seal is water-tight. This is particularly crucial for windows located on the ground floor of a building, since condensation may build up in the frame's bottom.

A good way to maintain the appearance of your windows is to paint them with a high quality paint. This keeps them looking new and shiny for longer, and protect them from UV rays. Double-glazed windows can make your home more peaceful and increase its value by making it more energy efficient and suitable for prospective home buyers to live in.

5. Glass that is damaged

Double-glazed windows are intended to help insulate your home by keeping out cold air and letting warm air into. This helps reduce the amount of sunlight that enters a room and protects your furniture from damage caused by sunlight. But sometimes, glass can get broken. A pebble could ricochet off a lawnmower or a strimmer and break a pane. A child might throw an object at it, or a mishap could happen. A damaged window can be an inconvenience.

Most often, a damaged or cracked pane can be repaired with epoxy or another similar product. It is crucial to wash the area and remove any old putty surrounding it prior to applying new epoxy. You can do this using a cotton rag soaked in linseed oil or the heat gun to soften and loosen the putty. Then you can scrape away the glass that has split and cut the edges to remove any remnants of old putty from the frame.

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 completely dry before installing the replacement pane. Be sure that the replacement pane is identical in size to the original. If you are replacing leaded glass, gently bend the lead in an H shape back over it.
