We carry out slipped glass panel repairs in Belfast and across the BT1 area. A slipped panel is a glass unit that has slid down its glazing bars, leaving a gap at the top and often pushing past the eaves at the bottom.

Signs you need slipped glass panel repairs
- Glass edge overhanging the eaves more than its neighbours
- A leak at the top of one pane only
- A pane that looks out of line with the others
What usually causes it?
Failed glass stops
Many systems use an end stop at the eaves. If it's missing or broken, nothing holds the glass in place.
Loose cappings
If the capping no longer clamps the glass firmly, the unit can creep with thermal movement.
About Belfast and the BT1 area
Damp, mild winters keep moss and algae growing on flat roofs and lantern frames, which holds water against seals and blocks weep slots. Regular clearing makes a real difference in wetter areas.
Near the coast, salt in the air is hard on aluminium finishes and fixings; washing the frame occasionally and touching in chips keeps corrosion away.
We also cover nearby Newtownabbey (4 miles), Holywood (5 miles), Lisburn (7 miles).
