Common Double Glazing Problems We Fix

  • Misted or foggy windows – caused by failed seals, reducing visibility and insulation.
  • Cracked or broken glass – replacing damaged panes while keeping your existing frames.
  • Draughty windows and heat loss – fixing worn seals and hinges to improve energy efficiency.
  • Condensation between the panes – restoring your glazing’s thermal efficiency.
  • Faulty hinges, handles and locks – ensuring smooth operation and better security.

Our Double Glazing Repair Services

Misted and blown window repairs

If your windows are fogging up between the panes, the seal around the sealed unit has failed and moisture has got in. It won’t clear on its own, and the unit no longer insulates properly. We replace just the glass unit, keeping your existing frame, which saves you money compared with a full window replacement.

  • Argon gas-filled, energy-efficient glass for improved insulation.
  • Soft-coat, warm-edge replacement units to reduce condensation.
  • Hassle-free fitting with no need to remove the frame.

Glass replacement and crack repairs

Accidents happen, and cracked or shattered double glazing can be a security risk. We replace broken glass with toughened or laminated safety glass where it’s needed, in uPVC, timber and aluminium frames. For larger or specialist jobs, see our glazing and glass replacement service.

Window and door mechanism repairs

Struggling with stiff windows, jammed locks or loose handles? We fix uPVC, aluminium and timber windows, including:

  • Faulty locks and handles – improving security and ease of use.
  • Worn or broken hinges and friction stays – restoring smooth opening and closing.
  • Damaged window seals and gaskets – reducing draughts and heat loss.

Repair or Replace?

If your frames are sound, replacing the glass and worn parts is usually far cheaper than new windows. If the frames are warped, rotten or beyond economical repair, we will explain why and talk you through new uPVC, aluminium and timber-look windows.

Double Glazing Repair Questions

Why is my double glazing misty between the panes?

The seal around the sealed unit has failed, letting moist air in between the panes. Once that happens it won’t clear, and the unit insulates less well. The fix is to replace the sealed unit.

Can you replace just the glass, not the whole window?

Yes. In most cases we replace only the sealed glass unit and keep your existing frame, which is much cheaper than a new window.

Can you repair broken window handles, hinges and locks?

Yes. We repair and replace handles, hinges, friction stays, locks and seals on uPVC, aluminium and timber windows.

Is it worth repairing old double glazing?

If the frames are in good condition, a repair is usually the better value. If they are warped or failing, we will tell you honestly and quote for new windows.

Do you fix misted conservatory glass?

Yes. We replace misted and broken units in conservatory walls and roofs. See our conservatory services.
