5 Glazing Repairs Lessons From The Pros
Glazing Repairs

The right repair of your window can boost your home's value. It will also improve the efficiency of your window or doors.

It isn't always easy to determine what the issue you're experiencing needs professional repair. Here are some of the most frequently encountered problems that require repair:.

Seals that are damaged

Window seals are a crucial part of your glazing system. They are used to secure windows, insulate them and seal them against outside air and moisture. Although they are designed to last a long time and could require repair or replacement, the truth is that they'll need to be replaced at some time. There are many options for repairs according to your budget and timeline.

Fogging inside your double paned IGU is one of the most frequent indicators that your window seals have failed. Foggy windows are caused by a broken seal between the two glass panes of your IGU which allows moisture to get in, causing condensation. Although you can try some quick-fixes to defog your windows, such as using a steamer or window putty, the most efficient solution is to get your window seals replaced by an expert.

In addition to allowing fogging and condensation between the windows, a weak seal could cause your windows to lose their insulation value. The space between the two panes of glass is filled with an inert gas such as xenon or argon which helps the IGU to resist heat transfer and keeps the heat in the home. When the window seal fails, the insulating benefit of your IGU will be lost and your energy bills will increase.

As time passes, rubber gaskets will begin to lose their elasticity due to aging and exposure. The degradation can be accelerated by improper care or by environmental factors like UV radiation. This can result in mildew and mold if it is not addressed. This can cause damage to the frame and sash on your IGU and ruin the appearance and weakening insulation.

The best way to prevent a breakdown of window seals is to carry out regular maintenance and avoiding common errors. Avoid using a high-pressure washer to clean windows since it can cause damage to the seal. Do not add reflective films to your window with insulation as this could void the warranty and damage the sealant. Also, be double glazing repairs when using chemicals, such as paint strippers because they can damage the sealant and cause it to fail.

Broken Glass

Broken glass is a hazard that needs immediate attention. A shattered pane within a window could fall and cause other windows to break, or create drafts, or let insects or water into your home. A glass pane that has been broken could also pose a risk for anyone who comes in contact with it, especially children or pets. In addition to being a risk for safety, shattered glass can be difficult to remove and may result in additional damage to frames, sash, and the surfaces that are adjacent to it.

The first thing to do when a windowpane is damaged is to seal it up with a cross patch of duct tape to stop further shattering. This will keep insects, rain and other debris out of the home until you are able to replace your glass. This method is especially important for windows that are higher up.

Next, take precautions by wearing thick cut-resistant gloves and eye protection. With a putty knife or pliers, pry out old glazing points, which are the tiny fasteners that pin glass into the frame's recesses. After the glass has been removed, clean the areas around it to prepare for the installation of a new replacement window.


It is essential to measure the window opening and make sure that the replacement is of the right size. Most glaziers will have standard-sized panes ready to insert however if you're looking for energy-efficient or safety glass it's likely to need to be made specifically for your frame. To avoid mistakes make sure you measure the opening of your window and subtract approximately 1/8 to 1/4 inch from the new pane.

When you're ready to install the glass you just bought, insert it with care into the frame and make sure it's a flush fit to the rabbets that support it. A glass pane that's too big can cause a cloud to form and swell on the surrounding wood, while one that's too small could fall off the frame and let drafts enter your home.

After you've ensured that the new pane is secured by a second cord of compound for glaziers around the edges of the glass to secure it to the frame and sash. Smooth the compound using your finger to ensure it is even around the new pane. Once dry paint the newly glazed compound and frame to match the rest of your window.

Structural Problems

The strength and structural integrity of curtain wall and framing systems is crucial for the safety, compliance, and performance of glazed surfaces. During an inspection, the expert will check fasteners, anchors, and supports to see if they are corroded, deteriorated, or misaligned. They also examine the gaskets and sealants to make sure they have been installed correctly and aren't leaking.

The structural issues that must be addressed include rusted frames as well as walls that are sagging. These problems are dangerous and could lead to severe damage with time. It is crucial to address any structural issues as quickly as possible to avoid costly repairs down the road.

Curtain wall systems need extensive structural support in order to withstand wind loads, and other stresses. The intrusion of water by these components can be costly and damaging. These failures are often caused by inadequate construction, design errors or inadequate installation.

Another problem that is frequently encountered is warping. This can cause distorted or deformed glass panels and affect the appearance of the system, energy efficiency, and safety. An inspector for glass looks for warping during an inspection and recommends repair steps if required.

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

For windows with wood frames, typical repairs involve missing or loose hardware. Two-part epoxy can be used to repair minor cracks on wooden window panes, but severely damaged or rotten wood is best replaced. Sashes that are stuck can usually be freed from their tracks by sanding them and applying graphite lubricant. Window companies made of aluminum are typically the ones to handle more complicated issues such as replacing sliding mechanisms, or major frame or sash components.

The cost of replacing an existing curtain wall system is usually higher than the cost of rehabilitation, however the energy savings and the increased comfort for occupants may allow the initial investment to be recouped. Additionally, a replacement system can assist in bringing the structure in line with the more strict building code requirements for insulated glazing and wind load resistance.

Sash Issues

Many sash window issues may be identified and resolved through a visual examination. Things like rotting wood, damage to paintwork and broken glass can all be identified with a professional assessment of the window, ensuring the window is in good shape for its future use. The most common problems are easily rectified and don't need replacement.

Issues like a sash window that won't open or close can be a hassle and also affect the efficiency of your home's energy usage. It's also a risk when windows suddenly slam shut, causing injuries, property damage and loss of cool or warm air.

Sliding windows require regular maintenance to ensure they look good and functioning well. Cleaning your window sash and spraying a lubricant can make them easier to open and close. If the issue persists, it could indicate that the balances aren't working properly or something is wrong with the sash.

Wooden window sashes absorb moisture over time, and are affected by changes in humidity. They can expand and shrink, which may cause them become stuck or encased within the frame. This can be prevented by ensuring a tight seal on the wood, and applying regularly a sash sealer or painting to protect against moisture.

Other sash problems that could occur are a damaged the sash lock cord displacement, nail jamming that can make sash windows harder to open and close. A carpenter can fix these issues by taking off the sash and fixing or replacing damaged parts, before reconnecting them.

Stained glass windows may be stained again to improve their appearance. It is essential to keep them in good condition to prevent water ingress and rot as well as other problems that can occur when the paint begins to peel and crack. Re-leading stained glass is another option to prevent it from leaking into surrounding wood and causing decay.
