Most jammed doors or stiff handles come down to a failed central gearbox rather than a ruined frame. We stock compatible mechanisms for all standard British uPVC and composite systems.
Gearbox Replacement
Door Realignment
Anti-Snap Upgrades
When handles spin loosely or latch bolts seize, we replace the central drive gearbox on your existing strip, saving the expense of complete lock replacement.
Dropped doors catch on thresholds and stress lock hooks. We re-toe and heel the glass panel and reset three-way flag hinges to restore smooth closure.
Upgrade vulnerable euro barrels to British Standard TS007 3-star rated cylinders with hardened steel pins that actively defeat lock-snapping attempts.




Clear sealed units fitted into existing frames
Misted Double-Glazing Replacement
When perimeter sealant degrades, moisture enters the air gap and creates permanent condensation. We measure, fabricate, and install a brand-new energy-efficient glass unit directly into your current uPVC, aluminium, or timber sash.
Friction Hinges and Perimeter Gaskets
Gaps around casement sashes cause draughts, whistled wind, and water ingress. We install heavy-duty stainless steel friction stays and insert fresh neoprene bubble gaskets to return airtight insulation to older frames.
Four steps from fault to fix

We attend your property across Leicestershire, check the tolerances, and supply a clear, fixed price before starting.
Using purpose-built gearboxes and calibrated hinges, we complete repairs on our initial visit wherever possible.
We adjust sash compression, demonstrate effortless key operation, clean the work area, and supply a written receipt.
