Why Glazing Repairs Could Be More Risky Than You Thought
Glazing Repairs

The right repair of your window will increase the value of your home. This can also increase the effectiveness of your windows or doors.

It isn't easy to tell whether the issue you're experiencing is one that requires professional assistance. Here are some of the most frequent problems that must be fixed:

Seals that have been damaged

Window seals are an essential part of your glazing system. They protect, insulate and seal windows against the elements of air and water. Although they are designed to last a long time and may require repair or replacement, the fact is that they'll need to be replaced at some moment. There are several options available for repair, based on your budget.

Fogging inside your double paned IGU is one of the most commonly reported indicators that the window seals are failing. Foggy windows are caused by a broken seal between the two glass panes of your IGU that allows moisture get in, causing condensation. While you can try some quick solutions to remove the fog from your windows, for instance using a steamer or window putty, the most effective solution is to get your window seals replaced by an expert.

In addition to allowing condensation and fogging between the window panes, a faulty seal could cause your windows to lose their insulating value. The space between your two panes is filled with an inert gas like argon or xenon, which aids the IGU in preventing thermal transfer and keep warm within the house. The benefits of the IGU's insulation will be lost in the event that the window seal is damaged. Your energy bills will also increase.

Over time rubber gaskets start to lose their elasticity due to aging and exposure. The degradation can be accelerated by insufficient care or by environmental factors, such as UV radiation. If not addressed, this may cause water intrusion into the building envelope resulting in the growth of mold and mildew. This can eat away at the frame and sash of your IGU and ruin the appearance and compromising insulation.

Avoiding common mistakes and executing regular maintenance is the best method to prevent window seals from breaking down. For instance, do not use a high-pressure washer to clean your windows, as it can work its way into the sash and damage the seal. Additionally, do not add a reflective window film to your insulated glass because it could void the warranty and harm the sealant material. Be careful when using chemicals such as paint strippers, as they can damage sealant and cause failure.

Broken Glass

Broken glass is a clear issue that requires immediate attention. A glass pane that has broken in a window may fall and break windows or cause a draft and possibly even water or insects to get into your home. A glass pane that is broken can be dangerous for anyone who comes in contact with it. This includes children and pets. In addition to being a risk for safety broken glass is difficult to remove and could cause additional damage to frames, sash, and other surfaces.

If a window is cracked, the first step is to seal it up with a cross-patch of duct tape to stop the glass from shattering further and keep rain, bugs and other debris out of your home until you are able to replace the glass. This method is particularly crucial for upper-story windows.

Wear thick, cut-resistant gloves. Also, wear eye protection. Utilizing a putty knife, or pliers, pry out old glazing points, or the tiny fasteners that hold glass into the frame's recesses. Once the glass is removed, clean the entire area to prepare it for a new window.

After determining the window's opening, it is important to ensure that the replacement is precisely the right size. Most glaziers have standard-sized panes that are ready to be inserted however if you're looking for energy-efficient or safety glass, it will likely need to be cut specifically for the frame. To avoid committing mistakes make sure you measure the opening of your window and subtract 1/8 to 1/4 inches from the new pane.

Once you're ready to put in your new glass, carefully place it in the frame. Make sure that it's perfectly with the rabbets. double glazing repair that's too big can cause a cloud to form and swell on the surrounding wood, while one that's too small can fall off the frame and let drafts enter your home.

Once you've confirmed that the new pane is secure to the frame, wrap another cord of compound for glaziers' around the perimeter of the glass to secure it to the frame and sash. Smooth the compound using your fingers to ensure it's level with the new pane. When dry paint the newly glazed frame and compound to match the rest of your window.

Structural Issues

The structural integrity of curtain wall frames and systems is vital to the security performance, performance, and conformity of glazed surfaces. During an inspection, a professional will examine anchors, fasteners and supports to determine if they are corroded, degraded or misaligned. He or she also checks the sealants and gaskets to ensure that they are properly installed and that they 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 cause serious damage over time. It is crucial to take care of any structural issues as soon as you can so that you avoid costly repairs later on.

Curtain wall systems require extensive structural support to withstand wind loads, and other strains. If these components fail, the water intrusion that occurs can be damaging and costly. The root causes of the failures are inadequate construction, design mistakes, and inadequate installation.

Another problem that is frequently encountered is warping, which can cause deformed or distorted glass panels and affect the appearance of the system, its energy efficiency and security. A glazing inspector looks for warping during an inspection and recommends repairs steps if required.

Glazing inspections should start by ensuring that the work area is free of obstructions and all workers are wearing appropriate safety gear. Gloves, hard hats and high-visibility vests form part of the safety equipment. It is also a good idea to use a harness and ladder to access higher or more difficult-to-access areas.

Common repairs for windows made of wood include loose or missing hardware. A few minor cracks in window frames made of wood can be repaired with an epoxy that is two-part, but damaged or rotten wood is typically better replaced. Sliding sashes that have become stuck in their tracks can be removed by sanding them and applying graphite grease. More complex issues like replacing sliding mechanisms and major sash or frame parts are typically left to aluminum window manufacturers.

The cost of replacing an existing curtain wall system is typically higher than the cost of rehabilitation, but the savings in energy consumption as well as the improved comfort for the occupants may let the initial investment be paid back. A replacement system may assist in bringing an existing structure into compliance with the more stringent standards of building codes for insulated glass and wind resistance to load.

Sash Issues

Visual inspections can help diagnose and address many issues with sash windows. Things like rotting timber and paintwork damage as well as broken glass can be picked up by a professional window assessment, ensuring the window is in good shape to be used in the future. The most common problems can be fixed easily and don't need replacement.

Problems such as the sash not closing or open could be frustrating and can affect the energy efficiency of your home. Your windows can also be risky if they suddenly snap shut. This can result in injuries, property damage and the loss of heat or air conditioning.

Regular maintenance is required to keep sliding sash windows in good condition and working well. Cleaning your sash windows and spraying them with lubricant can aid in opening and close more quickly. However, if the issue persists it could be a sign that the balances aren't operating properly or there's something wrong with the sash itself.

Over time, wooden window sashes can absorb moisture and can be affected by changes in levels of humidity. This causes them to expand and shrink, which can cause them to get stuck or trapped in the frame. This can be avoided by keeping a tight seal around the wood, and by applying a sash paint or sealer to protect against moisture.


Other sash problems that could be caused by a defective the sash lock cord displacement, nail jamming that can make windows more difficult to open and close. A carpenter can solve these issues by taking off the sash and replacing or repairing any damaged parts, before re-cording them.

It is possible to re-stain stained windows to bring back their original appearance. It is crucial to keep their condition to avoid water ingress and rot, as well as other issues that can occur when paint starts to peel and crack. Re-leading stained glass is an additional method to prevent it from leaking into surrounding wood and causing decay.
