Double Glazed Door Repairs

Double-glazed windows and doors keep draughts out, heat in and noise out, minimising the noise of barking dogs or traffic on nearby roads. They also act as a deterrent to burglars, as they are difficult to break.

However, just like other home improvement product, they can suffer from problems from time to time. This article will discuss the most frequently encountered problems and solutions.

Broken panes

A rogue pebble from the lawn mower, drinking too heavily on the glass-topped table, or the sudden weight of snow can cause windows to shatter. This could make your home vulnerable to the elements and is an ugly sight to behold. Fortunately, double-paned windows can be repaired by replacing the broken glass and restoring the frame. A professional window manufacturer can provide glass panes that can be replaced, but the repair is fairly simple to make yourself if have some experience working with wood-framed windows and some 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 glass can be brittle and hard. Wear gloves and a mask to shield your face from glass fragments flying around. Use a putty blade to pry out the old glazing compound from the recesses and the glazing points.

The pane's dimensions should be a little smaller than the rabbet grooves to allow the window to expand and contract in response to weather changes. Hardware stores can cut panes precisely to the required dimensions.

Once the new pane has been placed, roll a piece of glaziers' putty around the perimeter of the frame and into the glass-frame joint. If the putty is difficult to work with, dip a knife in linseed oil to soften it. Then, smooth the compound into place to create a smooth and even joint.

After the putty has dried paint it with exterior house paint. Let it dry for a few days. If you don't have exterior paint, you can also refinish the putty with wood varnish. Make sure to remove any varnish that is on the glass prior re-glazing it. This will stop the putty from sticking to the glass, causing a stain of water that could cause permanent damages.

Misted panes

Double glazing can help your home look modern and fresh. If you have double glazing that is misting or condensed between the panes it is not only unsightly but also makes your home feel cold and uncomfortable.


Double-glazed windows are constructed by sealing two panes of glass together and filling in the space with gas or air (such as argon or xenon) to create an insulating barrier that keeps heat in and cold out. Sadly, this seal can be damaged over time due to a variety of reasons. This could be due to aging environmental factors such as high humidity and temperature fluctuations, and problems with the installation.

It is crucial to fix the issue when it first occurs. If you leave it untreated, it could cause further damage and reduce the efficiency of your home.

Repairing double glazing isn't difficult. You can use a desiccant bag to absorb moisture, then re-instate the air seal, or you can drill holes in the window and clean the window with rubbing alcohol. However, this method requires a certain level of DIY skill and is not recommended for people who aren't confident drilling into their double pane windows.

Another option is to place a towel that has been soaked in vinegar between the window panes. This will help absorb moisture and prevent future condensation from forming. Once the towel is saturated put it away overnight, and then wash the window thoroughly with water to get rid of any vinegar residue.

There are kits that allow you to repair double-glazed windows without drilling holes. The glass is cleared from the outside by using dry pellets that disappear as time passes. These kits are cheap and extremely efficient in removing condensation from your double-glazed window. But it is important to keep in mind that this remedy only works for a short period of time and could need to be repeated often in accordance with the amount of moisture present in the air between the windows.

Sagging panes

If windows aren't correctly fixed or supported they may begin to lose their support over time. A sagging window is not just unsightly, but also indicates that the seals have failed, reducing the efficiency of the glass and frame. Visible condensation can be an indication of a sealant failing. It's also a sign it's time for windows to be replaced. Double-paned frames have the space between each pane is filled with silica. This gel can absorb water vapor and block condensation. This is the primary reason why double-paned glass windows are more energy efficient than single-paned windows.

Sagging windows can be corrected by securing the bottom of the frame by using L-brackets. This can stop the sash from sliding below the lower hinge shoe. This can be easily done by a double-glazing repair firm and is a relatively affordable method to fix your windows that have sagged.

Broken seals

Modern double-glazed windows feature window seals which are essential to keeping your home energy efficient and draught free. They are susceptible to being damaged or worn out and even impacted 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 an increase in your heating and cooling bills.

There are a few indications that you might have damaged window seals. These include unidentified drafts coming in from the window frame and fogging of the glass. The fogging of the glass is a sign that the seals are damaged and the inert gases (usually argon, or krypton) that were sealed between two panes are escaping. This allows moisture to get into the window. In the absence of attention, moisture can cause mold and dampness which could be hazardous to your family's health and comfort.

A broken window seal can also be identified by the presence of condensation on the glass, whether inside or on the outside. This is a common issue with modern double-pane windows which are sealed with an inert gas, which can form when the air temperature and glass temperature are at odds. If your windows are still providing a comfortable living environment and are still insulate, it is unlikely that the seals are broken or damaged. They are likely simply old and need to be replaced.

In the final analysis, ensure that the frame of the window and the surrounding area of the glass are free of any chips, cracks, or discoloration. These signs of damage could indicate that the frame is moving around the panes of glass and could cause the seal to break. You should have your windows professionally replaced every year, at a minimum, to ensure that they are working correctly.

There are a variety of methods for resealing your windows, but the best approach depends on the extent of the damage and the condition of your windows. To ensure you're using the right materials and techniques, it is recommended to consult with an expert prior to undertaking any DIY work on your windows.
