Double Glazed Door Repairs
Double-glazed doors and windows keep draughts away, heat in and noise out, reducing disturbance from dogs barking or traffic on nearby roads. They also act as a protection against burglars as they are tough to break.
But just like any other home improvement products they are susceptible to issues at times. This article will cover the most common issues and their solutions.

Broken panes
A stray piece of gravel from the lawn mower an unintentionally spilled drink laid heavy on your glass-topped coffee table or the abrupt weight of snow can all shatter window panes. This can expose your home to the elements, and is an unsightly sight to behold. Fortunately, double-paned windows can be repaired by replacing the broken glass and rebuilding the frame. A professional window manufacturer can produce replacement glass panes, however the repair is fairly simple to do yourself if you have some experience with wood-frame windows and a few basic tools.
The first step to fix a broken window is to remove the old window and glazing points from the frame. This requires some attention, as the old glazing is often hard and brittle. Wear gloves and a mask to shield your face from flying glass fragments. Make use of a putty knife to scrape the old glazing compound from the recesses as well as the glazing points.
Measure the opening for the new glass after taking out the old one. The pane's size should be a little smaller than that of the rabbet grooves in order to allow the window to expand and shrink as the weather changes. Hardware stores can cut panes precisely according to the required dimensions.
Once the new pane has been set, wrap a string of glaziers' glue around the frame's perimeter and into the glass-frame joint. If the putty appears too hard, you can soften it by dipping a knife in linseed. Smooth the compound into the joint to create a neat, even joint.
After the putty is dry paint it with a high-quality exterior house paint and allow it to set completely. If you don't have any exterior paint in your house, you could also refinish the putty using wood varnish. Just be sure to remove the varnish from the glass before attempting to glaze it again. This will stop the putty from sticking to the glass and leaving water staining that could cause permanent damage.
Misted panes
Double glazing is a great method to keep your home looking tidy and modern. But, if you've got double glazing that is misted or has condensation between the panes, it's not only unsightly but could cause your home to feel uncomfortable and cold.
Double-glazed windows are created by sealing two sheets of glass together and filling the gap with air or gas (such as xenon or argon) to create an insulating barrier that keeps heat inside and cold out. Unfortunately, this seal may break down over time for many reasons. These include age environmental factors like high humidity levels and temperature variations and problems with the installation.
It is essential to address the problem immediately after it happens. If not addressed, it can cause more damage and lower your home's energy efficiency.
The good news is that fixing your double glazing is relatively simple. You can either make use of a desiccant that absorbs moisture, and then put back the air seal or you could drill into the window. Clean the window by using rubbing alcohol. double glazing repairs does require a certain level DIY expertise and is not recommended for people who aren't at ease drilling into double pane windows.
A cloth soaked in vinegar can also be placed between the window panes. This will help absorb moisture and stop the build-up of condensation. After the towel has been soaked put it away overnight and then rinse the window thoroughly with water to remove any excess vinegar.
There are kits that allow you to repair double-glazed windows with no drilling holes. The glass is removed from the outside by using dry pellets which disappear over time. These kits are inexpensive and very efficient in removing condensation from your double glazed window. It's important to note that this remedy is only effective for a short period of time and may have to be repeated depending on the amount of moisture in the air between your windows.
Sagging panes
If windows are not properly secured or anchored they may start to shrink over time. A window that is sliding is not just ugly, but also means the seals have failed, reducing the energy efficiency of the glass and frame. Condensation visible is the primary sign of a failed sealant and is a signal that it's the right time to get windows replaced. In double-paned window frames, the space between each pane is filled with silica. This gel can absorb water vapor and prevent condensation. This is the main reason why double-paned windows are more energy efficient than single-paned ones.
Windows that are sagging can be fixed by securing the frame's bottom by using L-brackets. This will stop the sash from sliding below the lower hinge shoe. This can be easily done by a double-glazing repair service and is a fairly affordable method to fix your windows that are sagging.
Broken seals
The window seals found in modern double glazed windows play an important role in keeping your home efficient and free of drafts. They are susceptible to being damaged or worn out, or even damaged by extreme weather conditions. When a uPVC window seal is damaged, it can allow cold air to enter your home during winter, and hot air to escape in summer, which could result in a rise in your heating and cooling bills.
There are a few signs that you may have broken window seals. These include unidentified drafts that are coming from the window frame and fogging of the glass. The latter is a clear indication that the seals are damaged and the inert gas (usually argon or Krypton) which was vacuum sealed between the two panes has leaked out, allowing moisture into the window. In the absence of attention, moisture can cause dampness and mold which can be detrimental to your family's health and comfort.
A broken window seal is also evident by the presence of condensation on the glass, either on the inside or outside. This is a common issue for modern double-pane windows that are sealed with an inert gas, which may form when temperatures of the air and the glass clash. If your windows are insulating the property and providing a comfortable living space it is likely that the seals have been broken or blown away, but that they are simply old and in need of replacement.
The last thing to do is ensure that the window frame and surrounding area of the glass are free of any cracks, chips or discoloration. These signs of damage could indicate that the frame has moved around the glass panes which could cause the seals to fail. It is recommended that you have your windows sealed by an expert at least every year to ensure that they are working correctly.
There are a variety of ways to seal your windows. The best method depends on the condition and damage of your windows. To ensure you're using the right materials and techniques, it is best to seek advice from an expert prior to undertaking any DIY work on your windows.
