Why Glazing Repairs Is More Risky Than You Think
Glazing Repairs

Correctly repairing your glass will increase the value of your home. It will also improve the effectiveness of your windows or doors.

However, it isn't easy to tell what the issue you're experiencing is one that needs professional repair. Here are some of the most common problems that need to be fixed:

Seals that are damaged

Window seals are an essential element of your glazing system. They protect the windows, insulate them and seal against moisture and air outside. Although they are designed to last for a long time, and may require repair or replacement, the truth is that they will have to be replaced at some moment. There are several options available for repair, depending on your budget.

One of the most common indicators that your window seals are failing is the presence of fog in your double pane insulated glass unit (IGU). Foggy windows result from a damaged seal between the two glass panes of your IGU which allows moisture to be absorbed, causing condensation. While you can try some quick-fixes to defog your windows, such as using a steamer or applying window putty, the most efficient solution is to have 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, such as argon and xenon which helps the IGU resist heat transfer and keeps the heat inside the home. Once the window seal fails the insulation benefits of your IGU will be diminished and your energy costs will rise.

Rubber gaskets start to degrade with time because of exposure and age. The degradation can be accelerated by insufficient treatment or environmental factors such as UV radiation. This can cause mildew and mold if it is not dealt with. This can eat away at the frame and sash of your IGU and cause damage to the appearance and compromising insulation.

Avoiding common mistakes and performing regular maintenance is the best method to stop window seals from breaking down. For instance, you should avoid using a high-pressure washer to clean your windows as it can get into the sash and cause damage to the seal. Don't apply reflective films to your window that is insulated, since this could invalidate the warranty and harm the sealant. Be cautious when using chemical products, such as paint strippers because they can cause damage to the sealant and cause it to fail.

Broken Glass

Broken glass is an obvious problem that requires immediate attention. A cracked pane of glass in a window can be thrown down and cause additional windows to break or create a draft, or even allow insects or water to enter your home. A glass pane that has been broken can pose danger to anyone who comes in contact with it. This includes pets and children. Shattered glass is not only a risk to safety however, it can also be difficult to remove, and cause additional damage to frames and sash and other surfaces.


The first step to take when a window has damaged is to seal it up with a cross patch of duct tap to prevent further shattering. This will keep rain, bugs and debris out of the house until you can replace your glass. This is especially important for windows that are higher up.

Take precautions by putting on thick cut-resistant gloves and eye protection. Utilizing a putty knife, or pliers, pry out old glazing points, the tiny fasteners that pin glass into the frame's recesses. Once the glass is removed, you must clean the entire area to prepare it for a new window.

After determining the window's opening, it is important to ensure the new replacement is exactly the right size. Most glaziers will have standard-sized panes on hand, but if energy-efficient glass or safety glass is required, it may need to be cut to fit your frame. To avoid mistakes, measure the window opening and subtract approximately 1/8 to 1/4 inch from the new pane.

When you're ready to install the new glass, place it with care into the frame and check for a flush fit to the rabbets that hold it. A glass pane that is too big can cause the wood to expand, and a pane too small may be thrown out of the frame or allow drafts enter.

Once the new pane is secured, you can roll another glaziers compound around the perimeter to seal the glass to the frame and the sash. Smooth the compound with your finger to ensure it's even around the new pane. Once dry paint the newly glazed compound and frame to match the rest of your window.

Structural Problems

The structural integrity and performance of curtain wall and framing system are crucial for the safety, compliance and performance of glazed surfaces. During an inspection, the professional will examine anchors, fasteners, and supports to see whether they are corroded damaged or misaligned. He or she will also inspect the gaskets and sealants made of rubber to ensure 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 issues can be hazardous and could result in severe damage over the course of time. It is crucial to fix any structural issues as fast as you can, to avoid costly repairs down the line.

Curtain wall systems need extensive structural support in order to withstand winds, and other stresses. When these components fail, the water intrusion that occurs could be destructive and costly. The main causes for these failures include poor construction, design flaws and poor installation.

Another problem that is frequently encountered is warping, which can cause deformed or distorted glass panels that can affect the system's appearance, energy efficiency and safety. A glazing inspector looks for warping during an inspection and recommends repairs actions if necessary.

The first step of an inspection of the glazing is to make sure that the area of work is free of obstructions and that workers are wearing the appropriate safety equipment. This includes gloves, hard hats and high-visibility vests. It is also recommended to use a harness and ladder to gain access to higher or difficult-to-access areas.

Common repairs for wood-framed windows are missing or damaged hardware. A small crack in windows made of wood can be repaired with two-part epoxy, however damaged or rotten wood is typically better replaced. Sliding sashes stuck in their tracks can be cleared by sanding them, then applying graphite grease. Aluminum window companies are usually the ones to handle more complex issues like replacing sliding mechanisms or the major frame or sash parts.

Replacing an existing curtain wall system usually involves the cost of installation is much higher than rehabilitation, however the energy savings and increased quality of life for the occupants may eventually cover the initial investment. double glazing near me may also help bring an existing structure into line with the more stringent requirements of building codes for insulated glass and wind load resistance.

Sash Issues

Many issues with sash windows can be easily diagnosed and addressed through a visual inspection. Things like rotting timber and paintwork damage as well as broken glass can be detected with a professional assessment of the window, ensuring the window is in good shape for future use. The most frequent issues can be fixed easily and don't require replacement.

Problems such as a sash window that doesn't close or open can be a nuisance and could also impact your home's energy efficiency. Your windows can also be dangerous if they suddenly close shut. This can cause injuries, property damage and a loss of heat or air conditioning.

Sliding sash windows require regular maintenance to ensure they look good and working properly. Cleaning your sash windows and spraying them with lubricant can aid in opening and close more easily. However, if the issue persists it could be an indication that the balances aren't operating correctly or that something is wrong with the sash itself.

Over time wooden window sashes absorb moisture and be affected by changes in humidity levels. They can expand and shrink, which can cause them to get stuck or trapped in the frame. This can be prevented by ensuring a tight seal on the wood, and regularly applying a sash sealer or painting to shield against moisture.

Other issues with sash windows include a damaged cord displacement, lock and nail jamming. These all make it difficult to open and shut windows in sash. These issues can usually be resolved by carpenters who can take off the sash, repair or replace any damaged components, and then re-cord them.

Stained glass windows can sometimes be stained again to improve their appearance. It is important to maintain them in good condition to avoid water ingress and rot, as well as other issues that may occur when paint starts to peel and crack. Re-leading stained glass is an additional way to stop it from leaking into surrounding wood and causing decay.
