Glass & Glazing in Derry

Frameless screens use 8-10 mm toughened glass with polished edges and specialist hardware, priced per panel plus installation. Semi-frameless and framed options run meaningfully cheaper. Accurate templating matters — out-of-square walls are why this is not a DIY product.

Yes — emergency board-up is a core glazier service: they secure the opening with boards or film, clear the broken glass, and return with the correct replacement pane. Expect a call-out premium at night and weekends, and ask your insurer first as glass cover often includes an approved emergency line.

Toughened (tempered) glass is heat-treated to be several times stronger and crumbles into blunt granules when broken. Laminated glass sandwiches a plastic interlayer so it cracks but stays in place — better for security and overhead glazing. Codes dictate which is required where; laminated also blocks more noise and UV.

Glaziers price per pane by size, thickness and type: float glass is cheapest, toughened (tempered) safety glass costs roughly half again more and must be made to order, and laminated, obscured or low-E glass add further. Emergency board-up plus a return visit is the standard flow for breakages.

Shallow scratches can sometimes be polished out of thick glass and small edge chips stabilized, but cracks always spread — a cracked pane needs replacement. For sealed double-glazed units, any crack means replacing the whole unit since the seal is compromised.

Daytime board-up plus replacement typically runs £150-400 for a standard pane; out-of-hours call-outs add £80-150. Misted sealed-unit swaps land £100-300 per window.
