Glazing Repairs

The correct repair of your glazing will increase the value of your home. It will also improve the efficiency of your window or doors.

It can be tricky to know whether the issue you're experiencing is one that needs professional repair. Here are some of most common problems that need to be addressed:

Damaged Seals

Window seals are an essential element of your glazing system that protect, insulate and seal windows from outside air and moisture. They are designed to last for a long time however, the reality is that they could require repair or replacement 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 common signs that the window seals are failing. Foggy windows can be caused by an unsound seal between two glass panes in your IGU. This allows moisture to enter the IGU and create condensation. Steamers can be used to clear the windows or apply window putty. However, it's best to have your window seals fixed by an experienced professional.


A leaky seal could cause your windows' insulation value to decrease. The space between your two panes is filled with inert gas like argon or xenon which aids the IGU in preventing thermal transfer and retain heat within the home. If the window seal is damaged the insulation benefits of your IGU will be diminished and your energy costs will increase.

Gaskets made of rubber begin to degrade over time due to exposure and aging. Degradation can be accelerated due to improper care, or environmental factors such as UV radiation. This can lead to mildew and mold if it is not dealt with. This could eat away at the frame and sash of your IGU, destroying the appearance and weakening insulation.

The best way to prevent the loss of window seals is by performing regular maintenance and avoiding common mistakes. For instance, do not use a high-pressure washer to clean your windows, since it could be able to penetrate the sash, and damage the seal. Do not add reflective films to your window with insulation as this could void the warranty and harm the sealant. Finally, be careful when using chemicals such as paint strippers, as they can damage the sealant and cause it to fail.

Broken Glass

Broken glass is a problem that needs immediate attention. A broken pane in a window can fall and cause other windows to break, or create drafts, or allow water or insects into your home. A glass pane that has been broken can be a danger for anyone who comes in contact with it, particularly children or pets. Glass that has been broken is not just a risk to safety however, it can be a challenge to remove and can cause further damage to frames and sash and other surfaces.

The first step to take when a window has cracked is to tape it up with a cross-pattern of duct tap to prevent further shattering. This will keep rain, bugs and debris out of the home until you are able to replace your glass. richmond Double Glazing Repair is especially important for upper-story window.

Wear thick, cut-resistant gloves. Also, wear eye protection. With a putty knife or pliers, pry out old glazing points, the tiny fasteners that pin glass into the frame's recesses. Once the glass has been removed, clean the surrounding areas to prepare them for a new replacement window.

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

Once you're ready to put in the glass you just bought, insert it in the frame with care and check for a flush fit with the rabbets holding it. A glass pane too large can cause the wood to swell and a pane that's too small could fall out of the frame, or allow drafts get in.

Once you've confirmed that the new pane is secure by a second cord of compound for glaziers' around the glass's perimeter to seal it to the frame and sash. Smooth the compound with your fingers to ensure it is even around the new pane. After the compound has dried, paint it and the frame to match the window.

Structural Problems

The structural strength of curtain wall frameworks and systems for framing is crucial to the safety and performance of the glazed surfaces. During an inspection, a professional examines anchor points, fasteners, and supports for corrosion or deterioration. They also look for misalignment. He or she also checks the gaskets and sealants to make sure that they are installed correctly and that they are not leaky.

Rusted frames and sagging walls are structural issues that need to be addressed. These problems can be very risky and could cause severe damage over the course of time. It is essential to fix any structural issues promptly so that you avoid costly repairs down the line.

Curtain wall systems need extensive structural support to withstand wind loads, and other stresses. When these components fail the water intrusion that results can be costly and damaging. These failures are usually caused by inadequate construction, design errors and inadequate installation.

Warping can also cause distortion or deformed panels, which may impact the appearance, energy efficiency and security of the system. A glazing inspector will search for warping and recommend repairs if needed.

Glazing inspections should begin by ensuring that the work area is clear of obstructions and everyone is wearing the appropriate safety gear. This includes gloves, hard hats, and high-visibility vests. It is also recommended to use a harness and ladder to access higher or more difficult-to-access areas.

Common repairs for wooden windows include missing or loose hardware. A few minor cracks in windows made of wood can be repaired with a two-part epoxy, but damaged or rotten wood is generally best replaced. Sliding sashes that have become stuck in their tracks can be cleared by sanding them before applying graphite grease. Window companies made of aluminum are typically the ones to handle more difficult problems like replacing sliding mechanisms, or major frame or sash elements.

The cost of replacing the curtain wall system is usually greater than the cost of rehabilitation, but the energy savings and the increased comfort for occupants may make it possible for the initial investment to be returned. In addition, a replacement system can assist in bringing the existing structure into conformance with the more strict building codes for insulated glazing and wind load resistance.

Sash Issues

Many sash window issues may be identified and resolved through a visual inspection. Things like rotting timber or paintwork damage, as well as broken glass can be identified through a professional window inspection to ensure that the window is in good shape for future use. Most of the problems that arise are easily rectified and don't need replacement.

Problems like a sash windows that doesn't close or open can be a source of frustration and can also affect the efficiency of your home's energy usage. Your windows can also be risky if they suddenly snap closed. This could result in injuries, property damage and even a loss of air conditioning or heat.

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

Wooden window sashes take in moisture over time and are affected by changes in humidity. This causes them to expand and shrink, which can cause them to become stuck or jammed within the frame. This is prevented by maintaining a a tight seal around the wood and by applying a sash paint or sealer to guard against moisture.

Other sash problems that could occur are a damaged lock for sash cord displacement, cord displacement or nail jamming, which can make windows more difficult to open and close. A carpenter can solve these problems by removing the sash, fixing or replacing damaged parts, before reconnecting them.

Stained glass windows may be stained again to improve their appearance. It is important to keep them in good shape to safeguard the glass from water infiltration and rot that may occur when the paint starts to peel and crack. Re-leading stained glass is a different method to prevent it from leaking into surrounding wood and causing decay.
