Common Double Glazing Problems & Repairs

There is no need to rush for a window or door replacement the second you notice problems with your double glazing. There are many common problems that can be quickly rectified with the right repair work - a full replacement is not always necessary. 

Contemporary double glazing has an average lifespan of 20 years, but problems can arise over time. Here is a list of the most common double glazing issues and the work needed to repair them: 

• Windows/doors become difficult to open and close - Over time, window handles, hinges and opening mechanisms can become stiff and make it difficult to open and close them smoothly. The easiest fix for this issue is to apply oil to the different parts of the window. If a little lubrication is all that is needed, your windows should be working effectively again in no time.

• Locks not functioning correctly - Similar to above, if you are having trouble locking your windows and doors, try oiling the lock mechanism. If the stiffness persists, you can contact your installers and ask for a replacement lock to be fitted. It may be possible to repair and replace a faulty lock without needing to replace the entire double glazing unit.

• Condensation between the glass - If you notice water droplets or misting appearing between the two panes of double glazing, this means there is a fault in the seal somewhere and moisture has been able to make its way into the unit. It is possible to repair this issue, but you will need to call in the professionals. Condensation in double glazing can be resolved by drilling a hole into the glass pane unit and pumping in a drying agent to clear the moisture.

• Condensation in your double glazing can be prevented by ensuring your windows and doors are properly ventilated. Open your windows daily to allow fresh air to circulate and opt for windows with a trickle vent installed. Misting can be particularly problematic in the winter and is more likely to occur on older frames.

• Doors and windows ‘dropping’ in the frame - Double glazed windows and doors can change shape over time, especially if your home is situated in an area prone to extreme temperature changes. Frames can shrink and expand and this can cause problems with opening and closing. A quick fix to this problem is wiping the frames with cold water to shrink them back down to size. Dropped frames can also indicate a weakening of the hinges, this can be easily resolved with a hinge replacement.

---

• Failing seals - The seals around double glazing are in place to stop moisture from entering the unit and to prevent cold draughts from passing into your property. If you are noticing your home is colder than usual, this may be a sign that the seals have failed and need to be repaired. It may be possible to replace the failed seal without having to install new glass and frames. It is best to hire a professional to inspect your windows and carry out the required maintenance work.

These common double glazing issues can be repaired, depending on their severity and the condition of the rest of the unit. Repair work often seems like the best solution in the short term, but issues can be recurring and maintenance costs can soon add up. While double glazing can be repaired, if your frames are old and not providing optimum energy efficiency and security, a full replacement may be the best option.

Signs Double Glazing Needs Replacing

Sometimes repairing your double glazing is no longer an option and you will need to upgrade to new windows or doors. Contemporary double glazing provides superior temperature regulation and security and can also enhance the appearance of your property.

It may be time to upgrade your double glazing if you notice any of the following issues: 

• Chipped or cracked frame/glass - Any damage to your double glazing can allow cold air to enter your property and moisture to build between the glass panes. Condensation buildup can prevent the double glazing from performing at its best and can also lead to mould issues. This type of damage can be difficult to repair and a full replacement is the most sensible solution.

• Rising heating bills - If your double glazing is no longer providing effective heat regulation, it is likely time for a new installation. Rising heating bills and cold draughts are clear signs that your double glazing is no longer performing at its best. 

---

---

• Water leakage - Double glazing is manufactured to be weatherproof and watertight. If you notice water leaking in and around your windows, this is a sign of damaged seals or a water blockage somewhere in the frame. While you may be able to fix this problem temporarily, it is more cost-effective in the long term to choose a full replacement instead. 

• Decreased soundproofing - Double glazing can work as effective soundproofing for your property. However, if your home is just as loud with the windows closed as when they are open, this can be a sign that their performance is compromised and a new installation is needed.
