Repairing your glazing correctly can increase the value of your home. This will also improve the effectiveness of your windows or doors.

It can be difficult to determine if the issue you are experiencing requires professional help. Here are a few of the most frequent problems that must be addressed:

Damaged Seals

Window seals are a crucial part of your glazing system. They protect, insulate, and seal windows from outside air and moisture. Although they are designed to last for a long time and may require repair or replacement, the fact is that they will need to be replaced at some point. There are many options for repair, based on your budget.

Fogging in your double paned insulated glass unit is one of the most commonly reported indications that the window seals are failing. Foggy windows may be caused by the seal being damaged between two glass panes within your IGU. This can allow water to get in and cause condensation. Steamers are a great option to clear the windows or apply window putty. However, it's recommended to get your window seals repaired by a professional.

A leaky seal could cause your windows' insulation to decrease. The space between the two panes of glass is filled with an inert gas like xenon and argon, which helps the IGU to resist heat transfer and keep heat in the home. The IGU's insulating benefits will be lost in the event that the window seal is damaged. Your costs for energy will also increase.

Over time rubber gaskets begin to deteriorate due to age and exposure. The process can be accelerated by insufficient care or by environmental factors such as UV radiation. This can cause mildew and mold if not addressed. This could eat away at the frame and sash on your IGU and cause damage to the appearance of the building and compromising insulation.


The best way to prevent a breakdown of window seals is to carry out regular maintenance and avoiding common mistakes. Avoid using a high pressure washer to clean windows as it can damage the seal. Also, avoid adding a reflective window film to your insulated glass, as it could void the warranty and harm the sealant material. Be cautious when using chemicals, such as paint strippers, since they can cause damage to the sealant and cause it to fail.

Broken Glass

Broken glass is a clear issue that requires immediate attention. A broken pane in a window may fall and break windows, or create drafts and possibly even water or insects to get into your home. A broken pane of glass can pose danger to anyone who comes into contact with it. This is especially true for pets and children. In addition to being a safety risk broken glass is difficult to remove and may cause further damage to frames, sash and the surfaces that are adjacent to it.

If a window is cracked, the first step is to board it up with a cross-patch of ducttape to stop further shattering and keep rain, bugs and other debris out of your home until you can replace the glass. This is particularly important for windows with higher levels.

Wear thick, durable gloves. Also wear eye protection. Using a putty knife or pliers, remove old glazing points, or the tiny fasteners that pin glass into the frame's recesses. Once the glass is removed, wash the entire area to prepare it for a new window.

After measuring the window opening, it's essential to make sure that the replacement is precisely the right size. Most glaziers stock standard-sized panes that are ready to be inserted, but if you want security glass or energy-efficient, it's likely to have to be made specifically for your frame. To avoid mistakes take a measurement of your window's opening and subtract 1/8 to 1/4 inches for the new pane.

When you are ready to install your new glass, be sure to place it in the frame. Make sure that it's in a straight line with the rabbets. A new glass pane that's too huge could cause clouding and swelling of the wood surrounding it, whereas one that's too small can fall off the frame and let drafts enter your home.

Once the new pane is secured, you can wrap another piece of glaziers' compound around the perimeter of the pane to seal the glass to the frame and sash. Smooth the compound with your fingers to ensure it's level with the new pane. When the compound is dry, paint it and the frame to match the window.

Structural Problems

The structural integrity and performance of curtain wall and framing systems are essential for the safety, compliance, and performance of glazed surfaces. During an inspection, a professional checks anchor points, fasteners and supports for signs of corrosion, deterioration, or misalignment. double glazing window repairs examine the gaskets and sealants to make sure they are installed correctly and are not leaking.

The structural issues that must be addressed include rusted frames and walls that are sagging. These problems are dangerous and can lead to serious damage with time. It is crucial to address any structural issues as quickly as you can to avoid costly repairs down the line.

Curtain wall systems require extensive structural support to withstand winds, and other stresses. When these components fail the water intrusion that occurs can be costly and damaging. The main causes for the failures are poor construction, design flaws and poor installation.

Warping can also result in distortion or deformed panels which could affect the appearance, energy efficiency and security of the system. A glass inspector will look for warping during an inspection and suggests repair steps if required.

The first step of a glazing inspection is to ensure that the area of work has been cleared of all obstructions and that the workers are wearing the proper safety gear. This includes hard hats, gloves and high-visibility vests. It is also recommended to use a harness and ladder to gain access to higher or difficult-to-access areas.

For windows made of wood, the most common repairs involve a lack of or damaged hardware. Two-part epoxy can be used to repair minor cracks on windows made of wood, however severely damaged or rotten wood should be replaced. Sliding sashes stuck in their tracks can be cleared by sanding them, then applying graphite grease. More complex issues like replacing sliding mechanisms or major sash or frame parts are typically left to aluminum window manufacturers.

The cost of replacing the curtain wall system is usually higher than the cost of rehabilitation, however the energy savings and the improved comfort for the residents could allow the initial investment to be returned. Additionally, a replacement system can assist in bringing the current structure into compliance to more strict building code requirements for insulated glazing and wind load resistance.

Sash Issues

Many issues with sash windows can be easily identified and dealt with by a visual inspection. Things like rotting timber and paintwork damage as well as broken glass can be picked up with a professional assessment of the window and ensure that the window is in good order for future use. Fortunately, the most common issues are less severe and do not necessarily require replacement.

Issues like a sash window that won't open or close can be a source of frustration and also affect your home's energy efficiency. It's also risky if your windows unexpectedly slam shut and can lead to injuries, property damage, and loss of cool air or heat.

Regular maintenance is essential to keep sliding sash windows looking good and working well. Cleaning your window sash and spraying it with lubricant could make it easier to open and shut. However, if the issue persists, it could be an indication that the balances aren't working properly or there is something wrong with the sash itself.

Over time the wooden windowsashes absorb moisture and can be affected by changing levels of humidity. This causes them to swell and shrink, which can cause them to get stuck or trapped within the frame. This can be avoided by maintaining a tight seal on the wood, and applying regularly a sash sealer or painting to guard against moisture.

Other sash problems include a damaged lock, cord displacement, and nail jamming. These issues make it difficult to open and shut sash windows. They can be repaired by carpenters who can take off the sash, repair or replace any damaged parts and replace them with a new cord.

It is possible to re-stain stained windows to restore their original appearance. It is essential to keep their condition to prevent water ingress, rot and other problems that may arise when paint starts to peel and crack. Re-leading stained glass is a different way to stop it from leaking into the surrounding wood and causing decay.
