Double Glazing Windows Repairs
Double glazing refers to the panes of glass within a window frame or wall opening. The window glass can become faulty at times and requires repairs.
If you have noticed condensation between your windows, or a visible draft, or if hinges and handles become difficult to open, this could be an indication that your double glazing is in need of repair. This repair will typically involve replacing the entire unit.
Broken Panes
Double glazed windows are made up of two glass panes that have an air gap which is filled with inert gases like argon or krypton. This keeps the heat in your home while preventing cold drafts and moisture from getting in. Sometimes the windows may be damaged and the whole window may require replacement. It is crucial to contact the company who supplied you with double glazing immediately if you notice a chip or crack in the window.
A few simple steps can be taken to fix a broken window, however it is not recommended you attempt the repairs yourself unless you are an experienced DIYer. First you'll have to put on gloves and carefully remove the damaged pane. If it is cracked, apply strips of masking tape over the cracked areas in a crisscross design. This will stop the cracks from worsening over time, especially during the winter. You should also cover the work surface with newspapers to prevent any broken pieces from falling. Once the damaged pane is removed, scrape away any glazing putty or glazed window seal with a putty knife and remove the glazing points using pliers. Then, you can coat the unfinished wood with an easy-drying primer.
If you're able to buy a new replacement pane you can measure the length and width of the channel using a tape measure. Subtract 1/8" from both measurements to account for the slight movement of the replacement pane. Then, you can roll a thin rope of glazing compound into the channels with grooves and then slide the glass in place. Tap the glass gently using a hammer every 6" or 8" to help it set in its place. Be careful not to break it.
If you have a double-glazing warranty, it's often worth attempting to utilize this to avoid the cost of a full replacement window. Generally the warranty will cover the cost of any parts that you may require replacement, as well as labour. It is crucial to review the specifics of your warranty as it will vary from one company to the next so be sure to know what is covered and until when.
Foggy Glass
Foggy glass is often the result of condensation between the panes of your double glazing. It could be due to a number of things including temperatures, improperly installed frames, or even the deteriorating seals.
In most cases, double glazing contractors can fix this issue quickly and easily. It is important to contact the company who installed your windows immediately if you notice an issue, and make sure to document the issue in writing. This will make it easier in the event that you need to contact them again later on - and can be extremely helpful in the event that the issue is covered under your warranty or guarantee.
The most effective method to eliminate the fogging is by replacing gasket seals. This is done without the need to replace the entire window unit, and it will also help keep your home energy efficient. The window glazier will first take off the clips or retaining strips that hold the IGU and then use the saw to cut through the old sealant.
Then they will build or order a replacement IGU to fit the frame and apply special sealants in order to ensure it's airand water-tight. When they're done they'll install the retaining clips or strips and then apply sealant to ensure it's secure.
If you are lucky, the misting will stop. It's still important to make sure your frames are ventilated properly so that moisture doesn't accumulate within your ceilings and walls.
Another common problem faced by owners of double glazing is that their windows or doors become difficult to open and close It could be the result of extreme weather conditions, or it could be that the frame has dropped or sagged a bit over time, and isn't sitting flush with the rest of your home. If this is the case, try wiping the frames with cold water to shrink them a little - however, it's unlikely that this will solve the problem completely. If you're unable to resolve the issue, you might require an expert to replace them.
Condensation
Condensation occurs when the insulation gas in double-glazed windows fails to stay in place, leaving moisture and air between the panes. This is a frequent issue during winter, when humidity levels are usually higher, but it can occur at other times of the year too. Moisture can cause mildew and mould to grow around window frames, sealants and sills. This isn't just unattractive, but it's also dangerous for your health. The good thing is that condensation can often be resealed by a professional window installer to reduce the moisture level in your home and stop moisture from building up.
Window gaskets are an important element of any double-glazed windows or door. These gaskets aid in sealing in the air that is insulated between your window glass and stop drafts, heat, and moisture from entering or leaving your home. These gaskets can perish or shrink over time due to temperature fluctuations, weather conditions and aging, meaning that condensation could be appearing on your double-glazed windows or doors.
This can be fixed however, it will require replacement of the "sandwich" (thermo-pane and glass) in your double glazing window. It is recommended that unless you have the right tools, you employ an expert to seal your double-glazed windows.
Another common problem is mist that occurs between double-glazed windows. This is difficult to resolve. This indicates that the factory vacuum seal has failed, and there is no way to get air in or out of the sandwich.
A professional will reseal the windows with the same method as they would do for fog or condensation issues. This typically involves removal of the thermo-pane sandwich and spraying it with a cleaning solution and then sucking the sealant out of the old. It is important that you precisely measure the sandwich's length, width and thickness so that the replacement is a perfect fit and a new vacuum seal can be drawn between the glass.
This is a tough task that requires tools not often found in DIY stores. It's normally best left to professionals since faulty seals can lead to damp and mold in your home that could be expensive and harmful to your health.
Water Leaks
If you notice water leaks around your double-glazed windows it's important to respond quickly. If you don't act swiftly even the tiniest leak could be a huge problem.
The window frame could be the cause. Check to make sure the sill pan (the part that is flat at the bottom of the window frame) is pitched to drain water away from your home and not into the frame itself. If the sill pan isn't pitched correctly or if you see moisture in the wood you will need to contact a double glazing repair business for professional help.
Another reason for water leaks is a damaged window seal. This could be due to weather, age, or damage. This isn't as easy to fix, and is generally best left to the experts.
This can lead to lower efficiency of energy. This also allows cold air to enter your home in the winter months and hot air to escape during summer. This could result in expensive heating and cooling costs.
It is easy to fix it by applying a new layer of caulking. Although people who have DIY skills can do this themselves however, it is more efficient to let a double glazing specialist handle the job. This way, you'll get assurance and peace of mind knowing that the job will be done right.
Some double-glazed windows come with more info warranties that last up to 20 years. It is an excellent idea to inquire with the company you bought your windows from and find out what they cover and how long.
