5 Glazing Repairs Lessons From The Professionals
Glazing Repairs

Making repairs to your glazing correctly can increase the value of your home. This will also improve the efficiency of your window or doors.

It can be difficult to know if the issue you are experiencing requires professional help. Here are some of the most common problems that require repair:.

Damaged Seals

Window seals are an essential part of your glazing system. They secure the windows, insulate them and seal against outside air and moisture. They are designed to last for a long period of time, however, the reality is that they may need repair or replacement at some time. The good news is there are several options for repair depending on your budget and timeframe.

Fogging inside your double paned IGU is among the most frequent indications that the window seals are failing. Foggy windows are caused by a broken seal between the two glass panes of your IGU which allows moisture to be absorbed, causing condensation. Although you can try some quick fixes to clear your windows, like using a steamer or applying window putty, the most efficient 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 will also cause your windows to lose their insulating value. The space between the two panes is filled by inert gas such as argon and xenon that aids the IGU in preventing thermal transfer and keep warm within the house. Once the window seal fails the insulation benefits of your IGU will be lost and your energy bills will rise.

Gaskets made of rubber begin to degrade with time because of exposure and age. The process can be accelerated by improper care, or environmental factors such as UV radiation. This can lead to mildew and mold if it is not taken care of. This can eat away at the frame and sash on your IGU and ruin the appearance of the building and compromising insulation.

Avoiding common mistakes and performing regular maintenance is the best way to stop window seals from breaking down. For instance, do not use high-pressure washers to clean your windows, since it could get into the sash and damage the seal. Do not add reflective film to your window with insulation as this could void the warranty and damage the sealant. Be cautious when using chemicals like paint strippers because they can cause damage to sealant and cause failure.

Broken Glass

Broken glass is a concern that requires immediate attention. A cracked pane of glass in a window could be thrown down and cause additional windows to break, or create a draft, or even let insects or water into your home. A glass pane that has been broken can pose danger to anyone who comes in contact with it. This is especially true for pets and children. In addition to being a safety risk broken glass can be difficult to remove and could cause further damage to frames, sash and adjacent surfaces.

The first step to take when a windowpane is cracked is to tape it up with a cross patch of duct tap in order to prevent further shattering. This will keep rain, bugs and other debris out of the house until you can replace the glass. This method is especially important for windows that are higher up.

Next, take precautions by putting on thick protective eyewear and gloves that are cut-resistant. Utilizing 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 them for a new replacement window.

After measuring the window's opening, it is important to make sure that the replacement is exactly the right size. Most glaziers have standard-sized panes available to insert however if you're looking for energy-efficient or safety glass it's likely to need to be made specifically to fit your frame. To avoid any mistakes take a measurement of the window opening and subtract 1/8 to 1/4 inch to fit the new pane.


Once you're ready to put in your new glass, carefully place it in the frame. Make sure it is in a straight line with the rabbets. A new glass pane that's too big can swell and cloud the wood around it, while one that's too small may be thrown off the frame or let drafts in your home.

After the new pane is secured, you can roll 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. Once dry, paint the newly glazed frame and compound to match the rest of your window.

Structural Issues

The structural integrity and performance of curtain wall and framing system are essential for the safety, compliance and performance of glazed surfaces. During an inspection, the expert will check fasteners, anchors and supports to determine whether they are corroded deteriorated, or misaligned. They also check the sealants and gaskets to ensure that they are installed correctly and aren't leaky.

The structural issues that must be addressed include rusted frames as well as sagging walls. These issues can be extremely risky and could cause severe damage in the future. It is crucial to take care of any structural issues as soon as you can in order to avoid expensive repairs later on.

Curtain wall systems require substantial structural support to withstand winds and other strains. When these components fail, the resulting water intrusion can be costly and damaging. These failures are often caused by poor construction, design mistakes and inadequate installation.

Another issue that is common is warping, which could result in deformed or distorted glass panels and affect the appearance of the system, its energy efficiency and security. A glazing inspector will search for signs of warping and suggest repairs if needed.

The first step of an inspection of glazing is to ensure that the area of work is free of obstructions and that workers are wearing appropriate safety gear. Wearing gloves, hard hats and high-visibility vests are all part of the safety equipment. You can also utilize a ladder and harness to reach higher or more difficult-to-reach places.

Common repairs for wood-framed windows include missing or loose hardware. A small crack in windows made of wood can be repaired with an epoxy that is two-part, but rotted or severely damaged wood is typically better replaced. Sashes that stick can be removed from their tracks by sanding them and applying graphite grease. More difficult problems, such as replacing sliding mechanisms or the major frame or sash components are usually left to aluminum window manufacturers.

The cost of replacing the existing curtain wall is usually higher than the cost of rehabilitation, but the energy savings as well as the increased comfort of residents could let the initial investment be paid back. A replacement system can assist in bringing an existing structure in conformity with the stricter standards of building codes for insulated glass and wind resistance to load.

Sash Issues

Many issues with sash windows can be identified and resolved by an inspection. Things like rotting wood or paintwork damage, as well as broken glass can all be picked up with a professional assessment of the window and ensure that the window is in good order to be used in the future. Fortunately, the most common problems are less serious and do not necessarily require replacement.

Issues like a sash window that doesn't close or open can be a hassle and can also affect the efficiency of your home's energy usage. Your windows could also be risky if they suddenly snap shut. This can cause injuries, property damage, and the loss of heat or air conditioning.

Sliding windows require regular maintenance to ensure they look good and operating properly. Cleaning your windows for sash and spraying them with lubricant will allow them to open and close more quickly. If double glazing repairs persists it could be because the balances aren't working correctly or that something is wrong with the sash.

Over time the wooden windowsashes absorb moisture and be affected by changes in levels of humidity. This causes them to swell and shrink, which can cause them to become stuck or jammed 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 issues with sash windows include a faulty lock, cord displacement and nail jamming. These all make it difficult to open and shut sash windows. A carpenter can fix these problems by removing the sash and replacing or repairing any damaged components, then reconnecting them.

It is possible to re-stain stained windows to restore their original appearance. It is essential to keep them in good shape to prevent water ingress and rot, as well as other issues that may occur when the paint begins to peel and crack. Re-leading stained glass is a different option to prevent it from leaking into the surrounding wood and causing decay.
