UPVC windows should last years, but the handles, locks and mechanisms inside them don’t always keep up. When your windows start playing up – handles getting stiff, windows not closing properly, or that frustrating moment when they just won’t lock – that’s when you need someone who actually knows what they’re doing.
Swift Lock Repairs has been fixing UPVC windows across Northampton, Wellingborough, Bedford and surrounding areas for years. We’ll get them working smoothly again, usually without the need for costly replacements.
Common UPVC Window Problems We Sort Out
Stiff or Jammed Handles
That handle that takes both hands to turn, or won’t turn at all? Usually it’s the mechanism inside that’s worn out or needs adjusting. We’ll get it working smoothly again.
Windows That Won’t Close Properly
Really Annoying, this one. Especially when winter arrives. If your window won’t shut fully or lock into place, there’s likely an issue with the lock mechanism, hinges or how the frame sits. We’ll find the problem and fix it.
Broken Locks or Gearboxes
The gearbox is the bit that does all the work when you turn the handle. When it fails, your window won’t lock. We carry replacement parts and can usually fix this in one visit.
Damaged or Broken Hinges
Hinges wear out over time, making windows sag or catch. New hinges will have your windows opening and closing like they should.
Draughty Windows
Feeling a draught around your windows? Could be the seals have worn out or the frame needs adjusting. Either way, we’ll sort it and help keep your heating bills down.
Misted Double Glazing
While we mainly focus on the locks and mechanisms, if you’ve got condensation between the glass panes, we can advise you on getting the sealed units replaced.
