What we repair:
-
Sash windows — broken or slipped panes, failed putty lines, rattling glass, re-bedding and secure beading.
-
Timber doors — replacement safety glass to Part K critical zones; tidy making-good to mouldings and paint.
-
Shopfronts — replacement toughened or laminated panels, accurate templating and clean re-glazing.
-
Double-glazed units (where installed) — like-for-like sealed unit replacements in timber sashes or casements.
Glass options:
-
Clear float — standard single glazing for upper sashes and non-critical zones.
-
Laminated safety glass — improved security and acoustic benefit; suitable for low-level panes and doors.
-
Toughened safety glass — typical for shopfronts and doors; heat-treated for impact resistance.
-
Heritage glass — cylinder/restoration styles to mimic historic waviness for period façades.
-
Privacy & patterned — obscured/etched finishes for bathrooms and side returns.
-
Low-iron display glass — clearer colour rendition for retail displays (on request).
Note: We advise on safety glazing requirements (e.g., doors and low-level areas) and specify appropriate glass and thickness for each opening.
Sash window glazing — how we work:
-
Survey — confirm sizes, rebates and any timber or putty issues.
-
Preparation — protect the area; carefully remove broken glass and failing compound.
-
Timber repairs — localised splicing/repairs where rebates or beads are worn.
-
Re-glaze — bed the new pane, pin/bead as appropriate and tool clean putty lines for a sharp profile.
-
Finish — tidy make-good and touch-in primed putty edges; provide simple care notes.
Shopfront glazing — what to expect:
-
Templating & measure — accurate sizes for toughened/laminated panels.
-
Order & lead time — we source the correct spec and thickness for location and frame.
-
Installation — clean removal, set and seal; neat perimeter finishing and handover.
Temporary protection can be arranged where required and practical.

FAQs
Will the repair change how my window looks?
No — for period homes we match glass type and maintain slim sightlines. Putty lines are tooled to a sharp, traditional profile.
Do I need safety glass?
Glazing in doors and low-level areas typically requires a safety glass. We’ll advise the appropriate specification for each opening.
Can you match old wavy glass?
Yes — heritage cylinder/restoration glass can be specified for a period-correct look, subject to availability and size limits.
How quickly can you attend?
Lead times vary by glass type and size. We prioritise broken panes in doors or street-facing areas and can arrange temporary protection if required.
What affects cost?
Glass type and thickness, access, window condition (e.g., timber/putty repairs) and whether toughened/laminated or heritage glass is specified.
