uPVC window handle broken, won't lock, or letting in draughts? The frame is almost never the problem — it's the handle, locking mechanism, hinges, or seals. We carry standard replacement parts and fix on the same visit.
What We Fix
Most uPVC window faults are with hardware or seals — not the frame. Fixing the component costs a fraction of replacing the window.
Broken, loose or seized window handles replaced. We carry cockspur, cranked, and inline handle styles in multiple sizes for uPVC casement, tilt, and top-hung windows.
The espagnolette gearbox controls the window's locking points. When worn, the handle turns but nothing engages. We replace the mechanism to restore secure locking.
Egress, flag, and friction hinges on uPVC windows replaced when worn or seized. Keeps the window opening correctly and closing flush against the frame.
Child safety restrictors fitted to uPVC windows — required by regulations in rented properties with windows above ground floor. Supplied and fitted same day.
Perished rubber seals and gaskets around uPVC window frames replaced. Stops draughts, prevents condensation, and restores thermal performance without replacing the window.
Misted double-glazed units (failed sealed units) assessed and measured for replacement. We advise on whether the glass unit can be replaced within the existing frame.
