How We Can Help
• Handles supplied & fitted: key-locking espagnolette handles (inline/offset), tilt & turn handles, cockspur, and sash fasteners for timber. Finishes to match your décor (white, black, chrome, brass).
• Internal mechanisms replaced: espagnolette strips, multi-point shootbolts, tilt-and-turn gearboxes, keeps/strikers, cams and drive gears.
• Hinges & stays: friction stays, Egress/easy-clean hinges, butt/flag hinges and sash balances for uPVC, aluminium and timber—cures sagging, draughts and poor sealing.
• Safety & access control: child-safety restrictors, ventilation (night-vent) settings, keyed handles for insurance compliance and better key control.
• Repairs without replacing frames: failed gearboxes, seized handles, broken spindles, mis-aligned keeps, stiff or jammed sashes, windows that won’t open/close or won’t lock.
• Weatherproofing & alignment: re-toe & heel of sashes, gasket/trim replacement and hinge adjustment for a tight, rattle-free seal.
• Patio & roof windows: additional locks for sliding windows, secondary locks for rooflights and anti-lift devices where suitable.
Common signs you need us
• Handle turns but the window doesn’t lock/unlock.
• Key spins, or won’t come out.
• Window catches on the frame, feels loose, or is draughty/noisy.
• Tilt-and-turn stuck in tilt or won’t engage the turn position.
What you get
• On-site diagnosis and clear pricing.
• Quality, insurance-rated hardware where required, fitted neatly.
• Non-destructive methods wherever possible, and a parts & labour warranty.
From a single stiff handle to a full house of replacements, we’ll restore security, ease of use and proper weather sealing across your windows.
