Glazing Repairs
Repairing your glazing correctly will increase the value of your home. This can also increase the efficiency of your window or doors.
It can be a challenge to determine if the problem you encounter requires professional assistance for repair. Here are a few of the most common problems that need to be addressed:
Damaged Seals
Window seals are a crucial part of your glazing system. They secure, insulate and seal windows against outside air and moisture. They are designed to last for a long period of time, but the reality is they might require repair or replacement at some moment. The good news is that there are many options for repairs in accordance with your budget and timeline.
One of the most common indications that your window seals are failing is fogging in your double pane IGU, also known as an insulated glass unit (IGU). Foggy windows result from a damaged seal between the two glass panes of your IGU which allows moisture to get in, causing condensation. While you can try a few quick solutions to remove the fog from your windows, such as using a steamer or window putty, the best solution is to repair your window seals by a professional.
A failing seal can also cause your windows' insulation to decrease. The space between your two panes is filled with an inert gas like argon or xenon that helps the IGU resist thermal transfer and keep warm within the house. If the window seal is damaged the insulation benefit of your IGU will be lost and your energy bills will increase.
Over time rubber gaskets begin to lose their elasticity due to aging and exposure. Degradation can be accelerated through improper care, or environmental factors such as UV radiation. This can cause mildew and mold if it is not taken care of. This could eat away at the frame and sash of your IGU and cause a shabby appearance and damaging your insulation.
The best way to avoid a breakdown of window seals is by performing regular maintenance and avoiding common errors. For instance, avoid using a high-pressure washer to clean your windows, because it could get into the sash and damage the seal. Do not add reflective films to your window with insulation as this could void the guarantee and damage the sealant. Be cautious when using chemical such as paint strippers, as they can damage sealant and cause failure.
Broken Glass
Broken glass is a problem that requires immediate attention. A broken pane in a window can fall and break other windows or cause drafts and possibly water or insects to infiltrate your home. A glass pane that is broken can be dangerous for anyone who comes into contact with it. This includes pets and children. In addition to being a safety hazard, shattered glass can be difficult to remove and could result in additional damage to frames, sash, and the surfaces that are adjacent to it.
The first thing to do when a window is cracked is to tape it up with a cross-pattern 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 with higher levels.
Wear thick, cut-resistant gloves. Also, wear eye protection. With pliers or a putty take the old glazing points from the recesses of the frame. Once the glass is removed, wash the entire area to prepare it for a new window.
After measuring the window opening, it's essential to ensure that the replacement is exactly the right size. Most glaziers will have standard-sized panes available, but if energy-efficient glass or safety glass is required, it may need to be cut to fit your frame. To avoid committing mistakes, measure your window opening and subtract 1/8 to 1/4 inches for the new pane.
When you're ready to install the new glass, place it in the frame with care and ensure it's 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 that is too small could be thrown out of the frame or let drafts enter.
After the new pane has been secured, you can roll another glaziers compound around the perimeter to seal the glass to the frame and sash. Smooth the compound using your finger, ensuring it's evenly distributed around the new pane. Once the compound is dry paint it and the frame to match the window.
Structural Problems
The structural integrity and performance of curtain wall and framing systems are crucial to the safety, compliance and performance of glazing surfaces. In an inspection, a professional examines fasteners, anchor points, and supports for signs of corrosion or deterioration or misalignment. They also inspect the gaskets and sealants to make sure they are installed correctly and aren't leaking.
Structural issues that must be addressed include rusted frames as well as sagging walls. These issues are risky and could lead to severe damage over time. It is essential to address any structural problems as soon as possible in order to avoid expensive repairs later on.
Curtain wall systems require a lot of structural support to withstand wind loads and other stresses. The water intrusion caused by these components can be costly and destructive. These failures are usually caused by inadequate construction, design errors or inadequate installation.
Warping can also cause distortion or deformed panels which could impact the appearance, energy efficiency and safety of the system. A glazing inspector will look for signs of warping and suggest repairs if needed.
The first step in an inspection of the glazing is to ensure that the area of work has been cleared of all obstructions and that the workers are wearing the appropriate safety equipment. Hard hats, gloves, and high-visibility vests are all a part of the safety gear. You can also use a ladder and harness to reach higher or more difficult-to-reach places.
For windows made of wood, the most common repairs involve missing or loose hardware. double glazing repair in wooden window panes can often be repaired with an epoxy that is two-part, but damaged or rotted wood is usually better replaced. Sashes that are stuck can usually be freed from their tracks by sanding them and applying graphite oil. More complex issues like replacing sliding mechanisms and major frame or sash parts are typically left to aluminum window companies.
Replacing an existing curtain wall system usually involves the cost of installation is much higher than rehabilitation measures, but the energy savings and increased comfort of the occupants could eventually pay for the initial investment. A replacement system may assist in bringing an existing structure in line with the more stringent requirements of building codes for insulated glass and wind resistance to load.
Sash Issues
Many sash window issues may be easily identified and dealt with by an examination. Things like rotting wood and paintwork damage as well as broken glass can be identified by a professional window assessment to ensure that the window is in good condition to be used in the future. The most common problems can be easily fixed and do not require replacement.
Issues like a sash that doesn't close or open can be annoying and impact the energy efficiency of your home. It's also a risk when windows suddenly slam shut and cause injuries, property damage and loss of cool air or heat.
Sliding windows require regular maintenance to ensure they look good and working properly. Cleaning your sash windows and applying a lubricant spray will allow them to open and close more quickly. If the problem persists it could be because the balances aren't functioning properly or there is a problem with the sash.
Over time the wooden windowsashes absorb moisture and are affected by changing levels of humidity. They can expand and shrink which can cause them to get stuck or trapped in the frame. This can be avoided by maintaining a tight seal on the wood, and applying regularly paint or a sash sealer to shield against moisture.
Other sash issues include a damaged cord displacement, lock and nail jamming. All of these make it difficult to open and close windows for sash. These issues can usually be resolved by a carpenter who will remove the sash, replace or repair any damaged components and replace them with a new cord.
It is possible to re-stain stained windows to restore their original appearance. It's important to keep them in good condition to protect the glass from water ingress and rot which may occur when the paint begins to peel and crack. Re-leading stained glass is another option to prevent it from leaking into the surrounding wood and causing decay.
