Double Glazing Repairs
Repairs might be required if your double-glazed windows are difficult to open or show signs of condensation. This can often be done without having to replace the whole window unit.
Doing double glazing repair cost for double glazing requires special tools, which is why this should be left to a professional.
Condensation
Condensation in your double-glazed windows isn't just annoying it can also indicate that warm air is escaping your home. It's usually a sign the seal has been damaged or is becoming damaged. If this is the case, it's best to have the entire window replaced.
In some cases you might be in a position to use a hair dryer (from an appropriate distance) to eliminate the moisture between the glass panes. This is a good temporary solution, but it's also worth keeping in mind that you should seek out professional assistance as soon as possible as the longer the issue persists for a long time, the more damage it could cause to your double glazing and potentially to your health.
If the condensation is just on a small portion of your window frame you are usually able to eliminate it by wiping it down quickly and regularly. If you see condensation over a larger portion of the frame, it could mean that the seal is damaged and windows are not as efficient in thermal efficiency.
Internal condensation can be caused by a range of factors but is usually due to excessive humidity or poor ventilation in the house. The humidity can easily form droplets of water on cold surfaces and that's why double glazed windows are more likely to display condensation than older single-pane windows. If your kitchen or bathroom are particularly humid, you may require installing a vent to help reduce the humidity levels.
If your windows remain within their warranty you can contact the company that fitted them to describe the issue and ask them to fix the issue for you. They may be able to simply replace the window or they might need to fit one-way air vents in order to stop future condensation. This is a far better solution than simply replacing your double glazed windows entirely as it will save you time and money.
Foggy Glass
The windows that are stained with fog indicate that the seal on double-paned windows has failed. They have two glass panes with an opening between them, and this space is filled with energy-efficient gases such as argon or krypton. This helps keep temperature-controlled air inside your home, while keeping the outside elements out. If the seal is not strong enough it is possible that moisture will seep in and result in fog. Foggy windows aren't just unattractive, but they can also make your home less efficient in energy use.
Many homeowners choose to hire an expert to repair their windows rather than replace their windows. A glass specialist will be able to help determine if the windows are able to be fixed before making a recommendation. If they must be replaced they will be able to provide you with a top-quality replacement that won't be prone to foggy glass.
Another issue that double glazing that people experience is the windows or doors becoming difficult to open or close. This could be due to extreme weather conditions or changes to the structure of the frame. You should contact the company that sold you your double glazing if you discover it difficult to open. Many companies offer warranties on their products that last for a an agreed period of time. Some even provide lifetime warranties.
If you are unable to resolve the issue with your supplier it could be the right time to change providers. Always ask for written confirmation that your complaint has been acknowledged along with any agreements reached to fix it and when these dates will be. This will make it easier to switch providers if necessary.
Defogging is one method that can be used to fix foggy windows. This involves drilling holes into the glass, introducing an cleaning solution, then removing any soiled liquid, and drying the interior. This is a relatively new technique that is worth a look at whether it's appropriate for your home before you commit to it. It won't, however bring back the energy efficiency that's been lost due to the deterioration of seals.
Cracked Panes
A crack in a double-glazed window may appear to be a minor issue, but it can actually cause significant damage. It's crucial to have the crack fixed as quickly as possible in order to avoid further damage particularly if it's on inside of the glass.
Double-paned windows consist of two panes of glass that are glued together. The space between the panes is filled with inert gases, like argon or krypton. This is done to stop heat from your house from transferring through the glass. Gas also slows the transfer of heat so that the warm air in your home can move more slowly through the window than it would if there was nothing between the two panes of glass.
It's crucial that the windows are fitted correctly and have a solid seal. The windows must be installed by a licensed glazier who will be able to install the glass panes with a secure seal to ensure that they are insulated as effectively as possible. If the seal on the window has failed, the gas inside the panes might leak out and reduce their insulation capabilities, leading to cracks between the panes.
Another reason that is commonly cited for cracked double-pane windows is due to poor installation, which may result in the glass expanding and contracting at different rates. This can cause stress cracks that develop over time and can weaken the glass. If this happens, seek out a glazier who can replace the damaged glass with one that is more appropriate for your home.
If you discover a tiny crack in your double-glazed windows, it is crucial to realize that the crack is not repaired by filling it in with adhesive. Double-paned windows rely on an elongated seal between the two panes and any cracks will only worsen with time.
It is important to remember that handling broken glass can be hazardous and it's best to call in a professional glazier who will have the right tools to complete the task. They'll also know how to get rid of the old sealant, without causing damage to the glass.
Seals that leak
The IGU is made up of three or more parallel sheets annealed glass or tempered. The IGU is joined by the combination of polyurethane and aluminum spacers that creates an airtight seal between the windows that prevents water from entering your home. As time passes the seal can break down and allow water to leak into.
Most often it is due to the natural expansion and contraction of the components used to construct your window. The sealant, which is either silicone or polyurethane, can expand and shrink with changes in temperature and humidity which puts the IGU at risk of breaking. If the seal fails the insulative fill gas can escape and your windows will be left with a cloudy appearance and draughts that decrease the efficiency of your house.
If a window seal fails, it can also cause condensation or water between the panes that you can't wipe away. In certain cases the condensation may cause an indestructible stain on the glass of your window.
Generally speaking, you can fix the issue by having your windows professionally cleaned and sealed. This process requires specialized equipment that removes moisture, fills in the void with the gas argon or krypton and then reseals the window, preventing gas escape. The cost of this service can vary depending on the type of IGU and the location, but the majority of double-glazed windows can be repaired within an hour or two.
In addition to changing your window seals, there are a few other things you can do to increase the energy efficiency of double-pane windows. Select energy-efficient coatings and glass that reflect rather than absorb the sun's rays. This will keep your rooms cooler, more comfortable and improve the appearance of your windows. Finally, apply caulk or weatherstripping on the frame of your window to prevent gaps that can let cold air into your home and warm air to escape. In some instances, this is a better alternative to replacing the entire window.
