Double Glazed Windows Repairs

There are many reasons your double glazed windows might require repair, from condensation between panes to dropping or sagging frames. The majority of these issues are fixable.

Try applying lubrication to the hinges, handles and mechanisms of your door or window when it is difficult to open. This is a quick, affordable fix.

Broken Panes

If a window pane breaks, it loses its insulating properties and could cause a draft. If the dividing muntins also broken, it could cause water to leak through the glass panes resulting in condensation, mould and mildew and making your home less efficient in energy use. A broken window is best repaired by an expert to ensure that you get the correct seal and maximum energy efficiency.

First, you'll need to take the broken glass off. Start by placing a protective drop cloth under the broken window, and then scoring around the perimeter of the pane using an inexpensive glass cutter (available at most hardware stores). Before you begin, make sure to lubricate the cutter of this tool using an oil that is light. This will stop the glass from breaking too easily. The ball-shaped tool can be used to loosen the pieces. They should come off relatively quickly.

Scrape any old glazing compound from the recess of the frame once the glass has been removed. This will expose the glazier's point and metal clips that keep the pane in the frame. If there's any indication of corrosion, these should be replaced with new ones. If the window is wooden, the glazier's points can be reused if they're intact.

You'll then need to prepare the surface of the frame for re-glazing. With a caulking gun apply a continuous ribbon of compound around the inside edge of the recess. Use a high-quality putty, such as a Glazier's compound that is contained in cartridge. Allow it to dry before re-inserting the glass. Reinstall the metal clips if they are attached to the frame. Then, you can install the dividers.

Condensation

Condensation is a concern for double-glazed windows, especially in winter. It's typically caused by too much moisture in the home where warm air collides with cold glass, which then forms into water droplets and settles in the corners of your windows or across the frame. This can be prevented by opening windows more frequently and enhancing ventilation with extractor fans and running dehumidifiers in order to reduce the amount of moisture. If condensation is still present it is recommended to contact a professional who can diagnose the issue and repair or replace the windows if required.

It's also important to know that condensation on double-glazed windows can actually be an indication of a failing 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 fogging of the upvc window repairs and eventually mold growth if not addressed promptly enough.

Hairdryers can be used for a quick way to get rid of excess moisture. This is only a temporary solution and should only be used as a final resort. If the condensation is left for too long it could be looking at mould or dampness in your home, which must be addressed by a specialist.

For a more long-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 area to eliminate any moisture. During the process, they'll look for signs of damage, mould or mildew growth, and then apply a draught-proofing process to ensure that your windows are fully operational and energy efficient again.

Draughts

As time passes by, the rubber seals around the edges of your insulated glass can be damaged and cause a draught to form in the space between the two panes. This is typically a simple problem that can be fixed by replacing the gaskets and this will result in a solid and airtight seal once again. This will keep the warm air in your home, and the colder air out, thereby saving you money on your energy bills.

Double glazing that has mist could be a sign of blow-blown seals. The unit is comprised of two glass panes filled with argon separated by a spacer to create an airtight window. If the seal has blown the water vapour will get into your home through the gap. This will create condensation between the glass panes, which cannot be removed.

Fortunately it is a simple problem to fix and the windows can be replaced quickly by specialists who have all the right tools and know how to do it right. The expert will employ an instrument designed to push in the new seals. This is usually quicker than doing it by hand. The tools also have a pointed end that can be helpful to push the seals into the corners.

A professional could be able to seal your windows by drilling a small hole into the window, and then adding a desiccant, RepairMyWindowsAndDoors or putty. This is a less expensive option than replacing your double-glazed windows and still provides you with a reliable air-tight system for draughtproofing.

Faulty Hinges

Many people have had misted double glazing. It may be caused by a broken seal or a crack in the glass or an issue with the frame or mechanism. It is usually possible to fix this problem. It is usually a matter of creating a seal between two glass panes. The new seal will prevent leaks, condensation and draughts from happening.

Broken Seals

Double glazed windows are secured by seals on windows or gas. They can be damaged by various elements, including weather conditions, age and power washing. It is important to know the symptoms and how to repair them.

When a window seal breaks it allows moisture to enter between the two glass panes and create fog. It's a frequent issue and can cause the window to appear visually disoriented. When the seal is damaged, gas like argon as well as other inert gases are emitted from the window, thereby reducing the glass's insulating qualities.

A professional glazier can repair a damaged window seal with a brand new one. However, this is expensive and may not solve the fog issue completely. Some companies offer defogging which involves putting an air-pump inside the window frame in order to remove moisture and make the glass clear. This method isn't 100% reliable and does not replace inert gasses, meaning that fog could be re-created.

A glazier can also replace the entire IGU (insulated glass unit) if it is beyond repair. This is typically the most cost-effective solution and is a great option when you're looking for a long-term solution. However, it's best to choose a firm that has a warranty on replacement windows to ensure that any issues are protected. This way, you can rest at ease knowing that you'll get maximum value for your investment. You can also avoid the problem by selecting an item of high-quality and following the care instructions that are provided by the manufacturer. This will prolong the life of the window and decrease the amount of repairs.
