Misted Windows and Sticking Doors? Common Double Glazing Problems Explained

Double glazing is designed to improve energy efficiency, reduce noise, and enhance the security of a property. However, like any home improvement feature, it can develop issues over time. At A1 Glass & Glazing, an independent glazing and locksmith business based in Telford, we often help both domestic and commercial customers with a range of glazing problems. Below, we explain some of the most common issues with double glazing and what can be done to resolve them.

Misted or Foggy Windows

Why It Happens

Misted double glazing occurs when condensation forms between the two panes of glass. This typically means that the window seal has failed, allowing moisture to enter the space that should be airtight. Over time, changes in temperature and weather can cause seals to weaken, particularly in older units.

What You Can Do

If you notice fogging or mist inside the glass, the most effective solution is to have the sealed unit replaced. At A1 Glass & Glazing, we can quickly replace the affected unit without needing to change the entire window frame, saving time and cost.

Sticking or Jammed Doors

Common Causes

Double glazed doors—especially uPVC types—can sometimes become difficult to open or close. This can happen due to misalignment caused by temperature changes, worn hinges, or movement in the building structure. In other cases, the locking mechanism itself may be damaged or stiff from lack of maintenance.

Professional Repair

Our skilled team in Telford can diagnose and fix sticking or misaligned doors, ensuring they operate smoothly once again. As qualified Emergency Glaziers and locksmiths, we can also assist if the issue involves a jammed lock or if you are unable to secure your property properly.

Draughts and Heat Loss

When a double glazed unit is no longer sealing effectively, you might notice a cold draught or an increase in heating bills. Damaged seals, poorly fitted frames, or gaps around the glazing can all contribute to energy loss. Repairing or resealing your windows promptly helps maintain comfort and efficiency in your home or business.

Cracked or Broken Glass

Cracks in double glazed windows not only look unsightly but can also compromise insulation and security. Whether caused by accidental damage, vandalism, or thermal stress, prompt attention is essential.
