However, it can be tricky to know whether the issue you're experiencing requires professional assistance. Here are a few of the most frequent problems that require to be fixed:
Damaged Seals
Window seals are an important component of your glazing system. They protect the windows, insulate them and seal against the elements of air and water. They are designed to last for a long time, however, the reality is that they might require repair or replacement at some time. The good news is that there are a variety of options for repair according to your budget and timeframe.
One of the most common indicators that your window seals are failing is fogging in your double pane IGU, also known as an insulated glass unit (IGU). Foggy windows may be caused by the seal being damaged between two glass panes in your IGU. This can allow water to get in, causing condensation. While you can try some quick-fixes to defog your windows, like using a steamer, or applying window putty, the most effective solution is to repair your window seals by an expert.
In addition to allowing condensation and fogging between the window panes, a failing seal could cause your windows to lose their insulating value. The space between the two glass panes is filled with an inert gas such as argon and xenon, which helps the IGU to resist heat transfer and keep heat in the home. The IGU's insulating benefits will be lost when the window seal fails. Your costs for energy will also increase.
Over time rubber gaskets start to degrade due to age and exposure. Degradation can be accelerated due to poor care or environmental factors like UV radiation. If not addressed, this can cause water infiltration into the building envelope resulting in mold and mildew. This could eat away at the frame and sash of your IGU, destroying the appearance and compromising insulation.
Avoiding common blunders and performing regular maintenance are the best ways to stop window seals from falling apart. Avoid using a high pressure washer to clean windows as it can cause damage to the seal. Also, don't add a reflective window film to your insulated glass, as it could void the warranty and damage the sealant material. Finally, be careful when using chemical products, such as paint strippers because they could damage the sealant and cause it to fail.
Broken Glass
Broken glass is a clear problem that requires immediate attention. A broken pane in a window could fall and break windows, or create drafts and possibly even water or insects to get into your home. A glass pane that is broken can be a danger to anyone who comes in contact with it, including children or pets. Glass that has been broken is not just a safety risk however, it can be a challenge to remove, and cause additional damage to frames and sash as well as other surfaces.
The first step to take when a window has cracked is to tape it up with a cross-pattern of duct tape to stop further shattering. This will keep rain, bugs and debris out of the home until you are able to replace the glass. This method is particularly crucial for windows with higher levels.
Take precautions by putting on thick protective eyewear and gloves that are cut-resistant. With a putty or pliers, pry 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 measuring the window opening, it's important to ensure that the replacement is precisely the right size. Most glaziers will have standard-sized panes on hand, but if energy-efficient glass or safety glass is required, it might require cutting to fit the frame. To avoid mistakes take a measurement of the window opening and subtract 1/8 to 1/4 inch from the new pane.
When double glazing to install the glass, put it in the frame with care and check for an even fit with the rabbets holding it. A glass pane too large could cause the wood to swell and a pane that's too small can be thrown out of the frame, or allow drafts get in.
Once you've made sure the new pane is securely secured by a second cord of glaziers' compound around the perimeter of the glass to secure it to the frame and sash. Smooth the compound with your fingers to ensure that it's level with the new pane. After the compound has dried paint it on the frame to match the window.
Structural Problems
The structural strength of curtain wall frames and systems is vital to the security and performance of glass surfaces. In an inspection, a professional examines fasteners, anchor points, and supports for signs of corrosion or deterioration or misalignment. The inspector will also check the sealants and rubber gaskets to ensure they have been installed correctly and aren't leaking.
The structural issues that must be addressed include rusted frames and walls that are sagging. These issues can be extremely hazardous and could result in severe damage over the course of time. It is essential to fix any structural issues as soon as you can to avoid costly repairs down the line.
Curtain wall systems need extensive structural support in order to withstand wind loads, and other strains. double glazing caused by these components can be costly and damaging. These failures are usually caused by poor construction, design mistakes and inadequate installation.
Warping can also result in distortion or deformed panels which could impact the appearance, energy efficiency and safety of the system. A glazing inspector will search for warping and recommend repair measures if necessary.
Glazing inspections should begin by making sure that the work area is free of obstructions, and that all workers are wearing the appropriate safety equipment. This includes gloves, hard hats, and high-visibility vests. It's also a good idea to use a harness and ladder to gain access to higher or difficult-to-access areas.
Common repairs for windows made of wood include loose or missing hardware. Two-part epoxy is a good choice to repair minor cracks in wooden window panes, but severely damaged or rotted wood should be replaced. Sliding sashes stuck in their tracks can be loosened by sanding them, then applying graphite grease. More difficult problems, such as replacing sliding mechanisms or the major frame or sash components are usually left to aluminum window companies.
Replacing a curtain wall system typically involves a much higher upfront cost than rehabilitation measures, but the energy savings and enhanced quality of life for the occupants may eventually cover the initial investment. In addition, a new system could help bring the existing structure into conformance to more strict building codes for insulated glazing and wind load resistance.
Sash Issues
Many sash window issues may be easily diagnosed and addressed by an inspection. A professional assessment of the window can identify things like wood that is rotting or paintwork damage, as well as broken glass, ensuring that the window is in good shape for its future use. Luckily, the most common issues are less severe and don't necessarily necessitate replacement.
Issues like the sash not closing or open can be annoying and can affect the energy efficiency of your home. It's also risky if your windows unexpectedly slam shut and can lead to injuries, property damage or loss of heat or cool air.
Regular maintenance is required to keep sliding sash windows looking nice and working well. Cleaning your windows for sash and applying a lubricant spray can aid in opening and close more easily. If the problem continues, it could indicate that the balances don't work properly or there is a problem with the sash.
Over time, wooden window sashes can absorb moisture and are affected by the fluctuation in levels of humidity. They can expand and shrink, which may cause them to become stuck or jammed within the frame. This can be avoided by maintaining a tight seal on the wood and applying regularly a sash sealer or painting to guard against moisture.
Other sash problems that could be caused by a defective lock for sash, cord displacement and nail jamming that can make sash windows harder to open and close. These can often be fixed by carpenters who can take off the sash, repair or replace any damaged parts and re-cord them.
It is possible to re-stain stained windows to bring back their original appearance. It is important to maintain them in good condition to avoid water ingress, rot and other problems that can occur when the paint begins to peel and crack. Stained glass can also be re-leaded in order to stop it from leaking water onto the surrounding timber, causing wood decay.
