I carry the most commonly needed replacement parts and can usually finish the repair on the first visit. If your door needs a less common part, I'll explain the options. You can call me 24/7 if the door is stuck or won't lock.
The handle wasn't engaging properly, so I checked the locking mechanism and found a failed part. I replaced it, checked the door alignment and tested the lock before leaving. The door was locking properly again.
“Came within the hour on a Saturday afternoon and fixed the mechanism in the door very quickly. Very pleased with service provided.”

“Radu changed our locks and sorted a dodgy mechanism quickly and professionally and was able to attend at a time that suited us. Can't fault his work at all, thanks Radu.”
Becca Holden
“I was very grateful for Radu's help after my front door locking mechanism failed late at night and I was stuck outside my house. Radu arrived quickly, regained access and soon resolved the issue and made the house secure again. Highly recommended.”

Handle won't lift, key spins or your uPVC door won't open? Call and tell me what's happening. If the door is jammed shut, I'll try to open it without damage where practical, then check the lock and explain what needs repairing.
Call with your postcode and describe the problem, or send a photo on WhatsApp. I’ll discuss the likely repair options.
I’ll provide a free initial telephone or WhatsApp estimate where possible, without obligation. The final repair cost depends on checking the fault and any parts required; I’ll agree it with you before work begins. The free estimate does not include an on-site inspection, repair, labour or replacement parts.
Parts supplied by MobileLS are covered by a 12-month parts and workmanship warranty. Labour-only repairs where no parts are fitted are not covered by that warranty.
Many uPVC and composite door problems come from adjustment or an individual component, rather than the whole door failing. The door may need alignment, a gearbox or centre case, a multipoint strip, a cylinder, or handle and spindle work.
Where practical, I repair or replace the failed component and keep the parts that still work. A full mechanism replacement can be sensible when the strip or locking points are too worn to save; it is not the starting assumption for every stiff handle.
Once the repair is complete, the door needs to close, lock and open correctly. Replacing a part without checking alignment can leave resistance in the system, so the fit of the door matters as well as the lock.
Not every door or lock is repairable. Once I have checked the actual condition, I’ll explain what can be kept, what needs replacing and why.
Different faults can cause similar problems. I'll check the locking system and explain what needs repairing.
You do not need to name the part. Explain whether the problem started suddenly or became gradually stiffer, and whether the door is currently open, shut or insecure. A photo helps identify visible hardware, but cannot confirm the condition of the components inside.
Give your postcode, the door type and whether it will lock, open or move at all.
A photo of the handle, lock face or accessible door edge can help with preparation; don’t force the door for a photo.
On site, I assess alignment and the locking components; if the door is jammed, access comes first.
I carry out the chosen repair, then check that the door closes, locks and opens correctly.
The repair follows the fault, not just the symptom. These jobs show why a door needs checking before recommending replacement parts.
A uPVC or composite door that will not lock can have a failed gearbox, multipoint mechanism or an alignment problem. I have replaced a failed multipoint lock and realigned a uPVC door in LS8, and completed another multipoint repair in WF17. If the handle lifts but the door will not secure, or the key spins without engaging the lock, I’ll check the fault before recommending parts. A stiff handle does not automatically mean the whole mechanism needs replacing.
Leeds · Replacement parts
On this Leeds uPVC repair, the failed parts were confirmed before the handle and lock were replaced.
LS8 · Composite door
I repaired a composite-door lock in LS8 after the key stopped turning and the customer could no longer secure the door. The lock and door were tested after the repair.
These symptoms are clues, not a diagnosis. I check the door and locking system before deciding which parts, if any, need replacing.
Often points to alignment or a dropped door: the locking points may not line up with the keeps in the frame. It does not automatically mean the lock has failed.
Could be resistance from alignment, a worn gearbox or a multipoint mechanism fault. Forcing the handle can add strain to parts that are already struggling.
The movement may not be reaching the locking points. The gearbox, strip and alignment need checking rather than assuming that the visible handle is the cause.
A cylinder, gearbox or internal mechanism fault can cause this. Tell me whether the door is open or shut and whether the handle still moves.
A failed mechanism may have left the locking points engaged. Restoring access comes before inspecting the fault; non-destructive entry is attempted wherever practical.
This can indicate a dropped door, misaligned keeps or resistance in the mechanism. The fit of the door needs checking alongside the lock.
This includes back doors, double glazed doors, patio and French doors, as well as sliding patio door lock faults. If the door is insecure now, call before forcing it.
A dropped door, worn hinges or misaligned keeps can stop hooks and rollers meeting the frame correctly. If the lock works with the door open but struggles when closed, adjustment may be the right repair.
The centre case transfers movement from the handle and key to the locking system. Wear or failure here can stop the other locking points moving, even when the cylinder still turns.
The strip connects the locking points along the door edge. I check whether a failed centre case can be replaced separately or whether wear or damage calls for a correctly sized replacement mechanism.
The key operates the cylinder; the handle and spindle pass movement into the lock. A fault in one of these components may need a targeted replacement rather than a complete multipoint strip.
An awkward handle or key is a reason to have the door assessed. Repeated force adds stress to the mechanism and can make an existing problem worse.
Alignment, a worn gearbox, a failed multipoint mechanism or a cylinder fault can all stop a door locking. I check the door and components before recommending a repair; the symptom alone does not confirm which part has failed.
This often points to the door and frame no longer lining up correctly. A dropped door or misaligned keeps can prevent the locking points engaging. The fit and the mechanism need checking before deciding whether adjustment is enough.
Not necessarily. Alignment or resistance elsewhere in the mechanism can also stop the handle lifting. Avoid forcing it; the gearbox, locking points and door alignment need checking together.
Sometimes adjustment or replacement of the failed centre case is enough. If the strip or locking points are too worn or damaged, a correctly sized replacement mechanism may be needed. That still does not automatically mean replacing the whole door.
Yes, I attend doors stuck shut in Leeds. Non-destructive entry is attempted wherever practical. If another method is needed, I explain why before starting; the underlying lock fault can be assessed once access is restored.
Call with your postcode and describe the problem, or send a photo on WhatsApp. I’ll discuss the likely options and provide a free initial estimate where possible. The final repair cost depends on checking the fault and any parts needed, and is agreed before work begins.
Many faults can be dealt with through alignment or a replacement lock component. A new door is not the default solution, but not every door can be repaired. I’ll explain the options after checking its condition.
