Dungannon: window hinge replacement
A uPVC or composite door with a multipoint lock has one central gearbox that drives hooks, rollers or bolts along the door edge. A failed gearbox can leave the door stuck locked or unable to lock. In many cases only the gearbox needs replacing, not the whole strip.
Most modern windows use an espagnolette lock: a metal bar in the sash edge that moves locking cams into keeps on the frame when the handle turns. If the handle feels stiff or spins freely, the gearbox or bar may be worn, rather than the handle itself.
Draught seals and gaskets compress and shrink over time, letting in cold air and noise. Replacing them with a matching profile restores the seal without changing the window. The glazier checks the gasket type, as frames from different makers often use different profiles.
The cost of a window or door repair depends on the part needed, whether it is a standard or discontinued design, how easy it is to identify the make, the number of windows or doors, and access. Discontinued hardware sometimes needs a modern equivalent and adaptation to fit.

Working in Dungannon
- Postcodes covered
- BT71 and the surrounding area, including Cookstown, Armagh and Portadown
- Coast
- Dungannon is well inland, around 55 km from the nearest coast, so salt exposure is not usually a factor.
- Daylight and sun
- In Dungannon the midwinter sun reaches about 12° above the horizon at noon, with roughly 7.0 hours of daylight, rising to about 59° and 17.0 hours in midsummer. Windows and doors on sunny elevations expand and contract more with temperature, which can make them stick in summer and catch the frame. Dark-coloured doors absorb more heat, so hinge adjustment may be needed after hot spells.
- Access and setting
- Older rural homes may have timber casements, sash windows or doors with discontinued hardware, so parts may need matching or adapting. Exposed sites put more strain on hinges and seals, and outbuildings often benefit from upgraded locks.
- Rules in Northern Ireland
- For replacement doors and windows in Northern Ireland, PAS 24 products are a sensible choice for security.

Where a window provides an escape route, its replacement in Northern Ireland should give at least the same escape opening as before.

Window Repairs in Dungannon: questions
Can you find parts for old or discontinued windows?
Often, yes. Many hinges, locks and gearboxes are made to common sizes, and modern equivalents exist for many older designs. The glazier measures key dimensions such as backset, length and stack height. If an exact match is not available, the quote will explain the nearest option and any adaptation needed.
How do I look after window and door hardware?
Clean dirt from tracks, keeps and hinges, then apply a light machine oil or silicone spray to moving parts once or twice a year. Keep frame drainage slots clear. Do not force handles that feel stiff, as this can break gearboxes. Report a dropping door or sticking handle early, as small adjustments are easier than replacing parts.
Can sash windows be repaired instead of replaced?
Usually, yes. Broken sash cords, weak spring balances, sticking sashes and rattles can all be fixed on existing frames. The glazier replaces cords or balances, eases or replaces beads, and adds draught seals where needed. Repairing original sash windows also helps keep the character of older properties and conservation areas.
Is my euro cylinder lock secure?
Many older euro cylinders can be snapped, which lets an intruder open the door. Look for markings on the cylinder face. A TS 007 3-star mark, or certification to Sold Secure SS312 Diamond, shows the cylinder has been tested to resist snapping. The glazier can check and replace the cylinder with one cut to fit your door.
