Double Glazed Windows Repairs

There are many reasons your double glazed windows might need repairs, from condensation between panes, to draughts and dropped or sagged frames. Thankfully, most of these issues can be fixed.

If your door or upvc window repair is difficult to open, consider oiling the mechanism, hinges and handles. This is usually a low-cost solution that is quick and easy to fix.

Broken Panes

When a window pane breaks it loses its insulating properties and could cause a draft. If the dividing muntins are broken, it could cause water to leak through the glass panes, leading to condensation, mould and mildew and making your home less efficient in energy use. It is best to have a professional repair a broken window in order to get the most effective seal and energy efficiency.

The first step is to get rid of any broken glass. Start by placing a protective drop cloth under the window that has been broken and cutting around the perimeter of the pane with an inexpensive glass cutter (available at most hardware stores). It's a good idea to grease the cutter with light oil prior to when you begin. This will stop the glass from breaking too easily. Then, you can utilize the tool's ball-shaped end to loosen the pieces and the glass should break away fairly quickly.

After the glass has been removed, scrape off any old glazing compound that has accumulated in the recess area of the frame. This will reveal the glazier's facets and metal clips that keep the pane in place. Replace them if there is any corrosion. If the window is constructed of wood, the glazier points can be reused if they're still in good shape.

The remaining frame needs to be prepared to allow re-glazing. Using a caulking gun, apply a continuous strip of compound around the inner edge of the recess. Use a high-quality putty like glazier's compound that comes in a cartridge, or a standard compound that comes in a tin. Allow it to dry before re-inserting the glass. If the frame is made of metal clippings, they must be replaced as well. Install the dividers.

Condensation

Condensation can cause problems for double-glazed windows, especially during winter. This is usually caused by high moisture levels within your home. Warm air meets cold glass and condenses to droplets of water. These droplets then accumulate in the corners or frame of the window. This can be avoided by opening your windows more often, improving ventilation through extractor fans, and using dehumidifiers to reduce moisture levels. If condensation persists it is recommended to contact an expert who can identify the issue and fix or replace the windows if necessary.

It's also important to know that condensation on double-glazed windows can actually be an indication of a leaky seal. The seals that are applied at the factory can wear out over time and let cool air get between the panes. This can cause the window to become cloudy and eventually develop mold if it is not addressed immediately.

You can use a hairdryer for a quick way to eliminate excess moisture. This is only a temporary solution and should be used only as a last option. If the condensation has allowed to sit for too long it may be experiencing mould or dampness within your home, which must be addressed by a professional.

As a longer-term solution, you can have your double-glazed windows resealed by professionals. They'll take off the affected glass pane and clean the gap. They'll then pipe hot air into the space to dry out any moisture. During the process, they'll also check for any damage or growth of mildew, mould or mildew, and perform a draught proofing treatment to ensure that your windows are fully functional and energy efficient.

Draughts

Rubber seals can wear down over time and create drafts between your two panes. This is usually a minor problem that can be solved by replacing the gaskets, and this will result in a sturdy and airtight seal. This will keep warm air inside your home and colder air outside. You can reduce your energy bills.

Misted double glazing is a sign the seals of your sealed unit (sometimes called a DGU) have blown. The unit is composed of two glass panes filled with argon separated by a spacer to form an airtight window. If the seal has been blown the water vapour will get into your home through the gap. This can result in condensation between the glass panes that is not able to be removed.

Fortunately it is a simple problem to fix, and the windows can be replaced very quickly by professionals who have the appropriate tools and know how to do it correctly. The professional will employ an instrument that is designed to push into the new seals. This is typically faster than doing it manually. The tools also come with a pointed end which can be useful to push the seals into the corners.

A professional could be able to seal your windows by drilling a small opening in the window, and then adding a desiccant or putty. This could be a more cost-effective solution than replacements and it will still offer a reliable draught-proofing solution for your double glazing.

Faulty Hinges

Misted double glazing is a common problem that many people experience. It can be caused by broken or cracked glass frame or even a broken seal. It is often possible to fix this problem. This typically involves creating a seal between two glass panes. The new seal will prevent condensation, draughts, and leaks.

You should contact the company from whom you purchased your windows, and tell them of any problems immediately you notice them. Make sure you do this in writing and ask them to confirm that they've received your message. If there is a dispute the fact that everything is written will aid in proving your claim.

In some instances, a window repair specialist will cut the hole in your windows to draw out moisture and make the new seal. However, this is usually only a temporary solution and won't stop the moisture from returning. Alternatively, it may be possible to replace the glass unit itself which will ensure that it is watertight.

Make sure that you only attempt DIY fixes if your skills and knowledge are sufficient. Using super glue or another type of DIY solution can cause more harm in the long term. If you are unsure of what to do, it's always better to seek professional advice.

Broken Seals

upvc window repair seals, or insulation gas fills, are what keep double-glazed windows in place. A variety of factors can cause them to break, like weather conditions, age and power washing, therefore it's important to know what the signs are and how to repair them.

When a window seal fails it allows humidity to enter between the two glass panes, causing fog. This is a common issue that can also make the window appear distorted. Once the seal fails it is when any argon or other inert gas is removed from the glass, thereby decreasing its insulation properties.

A professional glazier can replace a broken window seal with a new one. This can be expensive and might not be able to resolve the fog issue. Some companies offer defogging, which involves putting an air pump inside the frame of the window to eliminate moisture and clear the glass. This method is not foolproof and does not replace the inert gasses, so the fog may come back.

If the IGU (insulated unit) is damaged beyond repair, a glazier could replace it. This is usually the most cost-effective option, and is a great option in the event you're seeking a long-term solution. It's best to select an option that provides a warranty on replacement windows. This guarantees that any issues that you might encounter are covered. This means you can be at ease knowing that you'll get most value from your investment. You can also try to avoid this issue by choosing a premium window and following the manufacturer's care instructions. This will extend the life of the window and cut down the amount of repairs.
