Glazing Repairs
The right repair of your window can increase the value of your home. This can also increase the effectiveness of your windows or doors.
It can be a challenge to determine if the issue you encounter requires professional assistance for repair. Here are some of most common problems that need to be addressed:
Seals that are damaged
Window seals are an essential component of your glazing system. They protect, insulate and protect windows from external 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 time. There are many options for repair, depending on your budget.
Fogging in your double-paned IGU is one of the most frequent signs 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 seep in, creating condensation. You can use a steamer to clear the windows or apply window putty. However, it's best to have your window seals fixed by a professional.
A leaky seal could cause your windows' insulation to decrease. The space between the two panes is filled with an inert gas like argon or xenon which assists the IGU in resisting 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 rise.
Rubber gaskets start to degrade with time because of exposure and age. Degradation can be accelerated due to improper care, or environmental factors like UV radiation. If not addressed, this can cause water infiltration into the building envelope resulting in mildew and mold. This can eat through the frame and sash of your IGU, ruining the appearance and compromising your insulation.
The best way to prevent the loss of window seals is to perform regular maintenance and avoiding common mistakes. For instance, do not use a high-pressure washer to clean your windows since it could get into the sash, and damage the seal. Additionally, do not add a reflective window film to your insulated glass, since it could invalidate the warranty and harm the sealant material. Be cautious when using chemicals like paint strippers as they can damage sealant and cause failure.
Broken Glass
Broken glass is a clear problem that requires immediate attention. A broken pane in a window may fall and break windows, or create drafts and even insects or water to enter your home. A broken glass pane can also be dangerous to anyone who comes in contact with it, including children or pets. In addition to being a risk for safety, shattered glass can be difficult to remove and could result in additional damage to frames, sash, and other surfaces.
The first step to take when a windowpane is cracked is to tape it up with a cross patch of duct tap to prevent further shattering. This will keep rain, bugs and other debris out of your house until you can replace your glass. This is especially important for upper-story window.
Wear thick, durable gloves. Also, wear eye protection. With a putty or pliers remove the old glazing points out of the frame recesses. Once the glass is removed, you must clean the entire area to prepare it for new window.
It is essential to measure the window's opening and make sure that the replacement is of the right size. Most glaziers have standard-sized panes available however if energy-efficient or safety glass is required, it could require cutting to fit your frame. To avoid committing mistakes take a measurement of your window's opening and subtract 1/8 to 1/4 inches from the new pane.
Once you're ready to put in the new glass, place it carefully into the frame and check for a flush fit with the rabbets that support it. A glass pane that's too huge can cause a cloud to form and swell on the wood around it, while one that's too small can be thrown off the frame or allow drafts into your home.
Once you've confirmed that the new pane is secured to the frame, wrap another cord of glaziers' compound around the perimeter of the glass to seal it to the frame and sash. Smooth the compound with your finger to ensure it's level with the new pane. After drying, paint the newly glazed frame and compound to match the rest of your window.
Structural Problems
The structural integrity of curtain wall frameworks and systems for framing is vital to the security and performance of glazed surfaces. During an inspection, a professional will check fasteners, anchors and supports to determine whether they have corroded, degraded or misaligned. He or she also checks the sealants and gaskets to make sure that they are properly installed and that they aren't leaking.
Rusted frames and sagging wall are structural issues that need to be addressed. These issues can be dangerous and may lead to severe damage in the future. It is important to address any structural issues as soon as you can, to avoid costly repairs later on.
Curtain wall systems require a lot of structural support to withstand wind loads, and other strains. Water intrusion caused by these components can be costly and destructive. The root causes of the failures are inadequate construction, design mistakes, and inadequate installation.
Warping can also lead to 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 start by making sure the work area is clear of obstructions, and that everyone is wearing the appropriate safety gear. Gloves, hard hats and high-visibility vests are all part of the safety gear. It's also recommended to use a ladder and harness to gain access to higher or difficult-to-access areas.
For windows made of wood, the most common repairs involve missing or loose hardware. A few minor cracks on 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 removed by sanding them before applying graphite grease. More complex issues like replacing sliding mechanisms and the major frame or sash components are usually left to aluminum window companies.
Replacing an existing curtain wall system usually involves a much higher upfront cost than rehabilitation options, however the energy savings and enhanced quality of life for the occupants may eventually cover the initial investment. A replacement system can help bring an existing structure in line with the more stringent requirements of building codes for insulation of glass and wind load resistance.
Sash Issues
Visual inspections can help identify and fix a variety of sash window problems. Things like rotting timber, damage to paintwork and broken glass can be identified with a professional assessment of the window and ensure that the window is in good shape to be used in the future. The most frequent issues are easily rectified and do not require replacement.
Problems such as a sash window that won't open or close can be a source of frustration and could also impact your home's energy efficiency. It's also a risk if your windows unexpectedly slam shut and can lead to injuries, property damage, and loss of cool or warm air.
Regular maintenance is essential to keep sliding sash windows looking nice 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 repair persists, it could be an indication that the balances aren't functioning properly or there is something wrong with the sash itself.
Wooden window sashes absorb moisture over time, and are affected when humidity levels fluctuate. This causes them to expand and shrink, which could cause them to become stuck or jammed in the frame. This can be avoided by ensuring a good seal on the wood and applying regularly paint or a sash sealer to shield against moisture.
Other sash issues that can occur are a damaged lock for sash, cord displacement and nail jamming, which can make sash windows harder to open and close. A carpenter can solve these issues by removing the sash, replacing or repairing any damaged parts, and then re-cording them.
It is possible to re-stain stained glass windows to restore their original appearance. It is essential to keep them in good shape to safeguard the glass from water ingress and rot which may occur when the paint begins to crack and peel. Stained glass can also be re-leaded to keep it from leaking water into the surrounding timber and causing decay of the wood.
