Glazing Repairs
Getting glazing repairs right will increase the value of your home. This will also improve the efficiency of your windows and doors.
However, it isn't always easy to determine whether the issue you're experiencing requires professional assistance. Here are a few of the most frequent problems that require fixing:.
Damaged Seals
Window seals are an essential element of your glazing system that protect, insulate, and protect windows from outside air and moisture. Although they are designed to last a long time and could require repair or replacement, the truth is that they will have to be replaced at some moment. There are many options for repair, depending on your budget.
One of the most obvious indicators that the window seals in your home are failing is a fogging issue in your double pane insulated glass unit (IGU). Foggy windows are caused by a broken seal between the two glass panes of your IGU that allows moisture seep in, creating condensation. Although you can try some quick-fixes to defog your windows, for instance using a steamer or window putty, the best solution is to have your window seals repaired by a professional.
In addition to allowing fogging and condensation between the window panes, a failing seal will also cause your windows to lose their insulating value. The space between the two glass panes is filled with an inert gas, such as xenon or argon, 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 removed and your energy costs will rise.
Over time, rubber gaskets will begin to deteriorate due to age and exposure. The process can be accelerated by improper care, or environmental factors such as UV radiation. If not addressed, this may cause water infiltration into the building envelope and result in the growth of mold and mildew. This can cause damage to the frame and sash on your IGU and ruin the appearance and weakening insulation.
Avoiding common blunders and performing regular maintenance are the best ways to stop window seals from being damaged. Avoid using a high-pressure washer to clean windows, as it can damage the seal. Do not apply a reflective film to your insulated window, because it could void the warranty and damage the sealant. Finally, be careful when using chemicals, such as paint strippers, since they can damage the sealant and cause it to fail.
Broken Glass
Broken glass is a clear issue that requires immediate attention. A cracked pane of glass within a window could fall and cause other windows to break or create a draft, or even let insects or water into your home. A broken pane of glass can be dangerous for anyone who comes into contact with it. This includes children and pets. In addition to being a risk for safety broken glass can be difficult to remove and may cause further damage to frames, sash and adjacent surfaces.
If a window is cracked the first step is to board it up using a cross-patch of duct tape to prevent further shattering and keep bugs, rain and other debris out of your home until you can replace the glass. This method is particularly crucial for windows with higher levels.
Next, take precautions by putting on thick protective eyewear and gloves that are cut-resistant. With double glazing repair or pliers remove the old glazing points out of the frame recesses. After the glass is removed, clean all the surrounding areas to prepare for the new replacement window.
After determining the window's opening, it's important to make sure that the replacement is the exact size. Most glaziers have standard-sized panes on hand however if energy-efficient or safety glass is required, it could require cutting to fit the frame. To avoid mistakes, measure the window opening and subtract 1/8 to 1/4 inch to fit 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's too large could cause the wood to expand and a pane that's too small can fall out of the frame, or allow drafts enter.
Once the new pane is secured, you can roll another cord of glaziers compound around the perimeter of the pane to seal the glass to the frame and the sash. Smooth the compound with your finger to ensure it's level with the new pane. After drying paint the newly glazed compound and frame to match the rest of your window.
Structural Issues
The strength and structural integrity of curtain wall and framing systems is crucial for the safety, compliance and performance of glass surfaces. During an inspection, the professional will inspect anchors, fasteners, and supports to see whether they have corroded, deteriorated, or misaligned. They also check the sealants and gaskets to ensure that they are properly installed and that they are not leaking.
Rusted frames and sagging wall are structural issues that must be addressed. These issues are risky and can lead to serious damage over time. It is essential to address any structural issues as fast as you can to avoid costly repairs down the line.
Curtain wall systems require extensive structural support to withstand wind loads, and other stresses. The intrusion of water by these components can be costly and damaging. These failures are often caused by inadequate construction, design errors, and improper installation.
Another issue that is common is warping, which can cause deformed or distorted glass panels, which can impact the system's appearance, energy efficiency and safety. An inspector for glass looks for warping during an inspection and suggests repair steps if required.
Glazing inspections should start by making sure the work area is clear of any obstructions and that everyone is wearing the appropriate safety gear. Gloves, hard hats and high-visibility vests are all a part of the safety gear. It is also recommended to use a ladder and harness to gain access to higher or difficult-to-access areas.
For windows with wood frames, typical repairs involve loose or missing hardware. A small crack in window frames made of wood can be fixed with two-part epoxy, however damaged or rotten wood is generally better replaced. Sashes that are stuck can usually be removed from their tracks by sanding and applying graphite lubricant. Aluminum window companies are typically the ones who handle more complex issues like replacing sliding mechanisms, or major frame or sash elements.
The cost of replacing the existing curtain wall is usually higher than the cost of rehabilitation, but the energy savings and the increased comfort for people living in the structure could make it possible for the initial investment to be recouped. Additionally, a replacement system can assist in bringing the structure in line to more strict building codes for insulated glass and wind load resistance.
Sash Issues
Visual inspections can help identify and resolve a number of issues with sash windows. A professional window inspection will reveal things like rotting wood, paintwork damage and broken glass, ensuring that the window is in good order to be used in the future. Fortunately, the most frequent problems are less serious and do not necessarily require replacement.
Problems like a sash windows that isn't able to open or close can be a source of frustration and also affect the efficiency of your home's energy usage. It's also a risk when windows suddenly snap shut, causing injuries, property damage or loss of heat or cool air.
Sliding sash windows need regular maintenance to keep them looking good and functioning well. Cleaning the window of your sash and spraying lubricant on it can make it easier to open and shut. However, if the issue persists, it could be an indication that the balances aren't operating properly or there is something wrong with the sash itself.
Wooden window sashes take in moisture over time and can be affected when humidity levels fluctuate. This causes them to expand and shrink, which could cause them to get stuck or trapped within the frame. This can be avoided by keeping a tight seal around the wood, and by regularly applying a sash paint or sealer to protect against moisture.
Other sash issues include a faulty lock, cord displacement 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, replace or repair any damaged parts and re-cord them.
Stained glass windows may be re-stained to restore their appearance. It is essential to keep their condition to avoid water ingress and rot as well as other problems that may arise when 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.
