Double Glazing Repairs
If your double-glazed windows are difficult to open or show signs of condensation it may be time for repairs. This can often be done without having to replace the whole window unit.
Doing the repair yourself for double glazing requires special tools, and should be left to professionals.
Condensation
The sight of condensation in your double-glazed windows isn't just an inconvenience, it also means that warm air is escaping your home. It's usually a sign that the seal has broken or is becoming damaged. It's best to replace the entire window if this is the case.
It is possible, in some cases, to use a hairdryer to evaporate the moisture between the glass panes (from an in-between distance). This is a great temporary solution, but it's worth keeping in mind that you should seek professional help as soon as possible as the longer the problem persists and the longer it lasts, the more damage it will cause to the double glazing, and possibly to your health as well.
If the condensation is limited to a tiny portion of the window frame, it is usually possible to remove it by wiping it down frequently and swiftly. If you see condensation on a larger area of the window frame it could indicate that the seal is damaged and windows are less thermally efficient.
Internal condensation can be caused by a variety of reasons, but it's typically down to excessive humidity and/or inadequate ventilation in the house. Double-glazed windows tend to show more condensation than older single pane windows since humidity is able to form water droplets on cold surfaces. If your bathroom or kitchen are especially humid, you may require installing an air vent to reduce the humidity levels.
If your windows are still under warranty, you can get in touch with their installer to explain the issue and request to address the issue. They might be able to simply replace the unit or may have to install one-way vents in order to prevent future condensation. This is a better solution than replacing your double-glazed windows because you'll save time and money.
Foggy Glass
Foggy windows are a sign that the seal on double-paned windows has failed. These windows have two glass panes that have space between them and this space is filled with energy-efficient gases like Krypton or argon. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. If the seal fails, water can enter and cause fog. double glazing repairs cost aren't just unattractive, but they can also make your home less efficient in energy use.
While windows can be replaced when they're leaking some homeowners prefer hiring a professional for window repair instead. A glass specialist can help determine if the windows can be repaired before making recommendations. If they must be replaced they will be able to provide you with a high-quality replacement that won't be susceptible to foggy glass.
Double glazing can also cause problems with the opening or closing of windows or doors. This can be caused by extreme weather conditions or a change in the frame's structure. If you notice that your double glazing is difficult to open, a good first step is to speak to the business you purchased it from. The majority of companies have warranties that provide their products for a certain period of time, and some even offer lifetime warranties.
If you are unable to solve the issue with your supplier, it may be time to switch providers. You should always ask for written confirmation that your complaint has been received and any agreements signed to address the issue and when these dates are. This will make it easier to change providers if needed.
Defogging is a technique that can be used to repair foggy windows. This involves drilling holes into the glass, injecting an cleaning solution, then removing any liquid that has been soiled and drying the inside. This is a relatively new method that is worth a look at whether it's right for your home prior to committing to it. Remember, however that it can't bring back any energy efficiency lost due to damaged window seals.
Cracked Panes
A crack in a window that is double-glazed may seem like something minor but it could cause significant damage. It is crucial to get the crack repaired as quickly as you can in order to avoid further damage, particularly if it's on inside of the glass.
Double-paned windows are made up of two panes of glass which are joined together. The space between the panes is filled with inert gasses, such as argon and Krypton. This is to prevent heat from your house from passing through the glass. The gas slows heat transfer, meaning that the warm air from your home will travel through the window more slowly than if there were nothing between the panes of glass.
When installing, it is essential that the windows are installed properly and with a top-quality seal. The windows should be fitted by a glazier who is qualified, who will be able to install the glass panes with a secure seal to ensure that they are properly insulated to the best extent. If the window seal is not working it may cause the gas inside the panes to leak and reduce their insulation properties and leading to cracks between the two panes of glass.
Another reason that causes cracked double-pane windows is poor installation, which can cause the glass to expand and contracting at different rates. This could cause stress cracks to develop over time, which weakens the glass. If this happens, you should locate a glazier to replace the broken glass with one that is more suitable for your home.
If you notice a tiny crack in your double-glazed windows it is important to know that the crack is not repaired by simply filling it in with adhesive. Double-paned windows depend on an elongated seal between the two panes, and cracks are likely to get worse as time passes.
It is crucial to keep in mind that broken glass can be dangerous. Therefore, it's best to call a professional who has the right tools to do the job. They'll also know how to remove the old sealant without causing damage to the glass.
Seals that leak
The IGU consists of three or two sheets of glass that are annealed or tempered. The IGU is held in place by a combination aluminum spacers, and polyurethane. This creates an airtight seal that stops water from entering your home. In time, however the seal may be damaged and allow water and draughts to get into your living spaces.
This is usually caused by the natural expansion or contraction of materials that were used to make your window. The sealant (silicone or polyurethane) can shrink and stretch slightly with changes in temperature and humidity and can put IGUs at risk of bursting. If the seal fails the insulative fill gas can escape and your windows will be left with a hazy appearance and draughts which reduce the efficiency of your home.
If a window seal is damaged it can cause condensation or water between the panes, which you are unable to remove. In some cases the water may leave an indestructible stain on your window glass.
Typically, you can correct the issue by having your windows professionally defogged and resealed. This process requires specialized equipment that removes moisture, fills in the void with Krypton or argon gas, and then reseals the window without letting gas escape. The cost of this service can vary depending on the type of IGU and the location, but most double glazed windows can be repaired in one or two hours.
You can increase the energy efficiency and comfort of your double-paned windows by doing several things, including replacing the window seals. Select energy-efficient coatings and glass that reflect instead of absorbing the sun's rayons. This will keep your rooms cooler, more comfortable and improve the appearance of your windows. Also, you can use caulk or weatherstripping on the frame of your window to eliminate gaps that can allow cold air into your home and warm air to escape. In some instances this is a good alternative than replacing the entire window.
