Emergency Glazier
UK& Surrounding Area

Condensation between the panes of a double glazed window means the seal has failed. The airtight seal around the edge of the unit has broken down, allowing moist air to enter the gap between the panes. Once the seal has gone, the unit cannot be repaired — the sealed unit needs replacing. This typically costs £150–£350 per window and does not require replacing the frame.

Yes, in most cases the sealed double glazing unit can be replaced without changing the frame — this is called a 'unit swap' and costs significantly less than a full window replacement. The glazier removes the beading, takes out the failed unit, and fits a new sealed unit into the existing frame. This is the standard repair for misted, condensation-filled, or cracked double glazing.

A cracked window is not always an immediate emergency, but it should be dealt with promptly. Cracks weaken the glass and can spread rapidly, especially in cold weather when temperature changes cause the glass to expand and contract. If the crack compromises security or there is a risk of the glass falling out, treat it as urgent and call an emergency glazier.

Storm-damaged windows can usually be repaired by replacing the broken panes rather than the entire window frame. If the frame itself is damaged or warped, a full window replacement may be needed. Contact your home insurer promptly — storm damage is typically covered under buildings insurance. An emergency glazier can board up immediately and then assess whether repair or replacement is the best option.

Wear thick gloves and closed-toe shoes before approaching broken glass. Pick up large shards carefully and wrap them in newspaper before placing in a cardboard box — never put loose glass directly into a bin bag. Use damp kitchen roll to pick up small fragments and splinters from the floor. Vacuum the area thoroughly afterwards, and check for stray pieces in curtains, furniture and soft furnishings.

Most emergency glaziers covering UK aim to arrive within 30 to 60 minutes for urgent jobs like break-in damage or dangerous broken glass. For boarding up, they can usually secure your property within the hour. Permanent glass replacement typically follows within 24 to 48 hours once the correct glass has been ordered.
