The detail that matters

Can the central case be replaced on its own?
Sometimes, where a compatible part exists and the rest of the assembly is suitable to retain.
Why assess the door alignment as well?
Unresolved pressure or misalignment can continue to strain a new gearbox after replacement.
What should I include in this enquiry?
Have the postcode, photographs of the lock and door, and a short account of when the fault began. Identify the person authorised to arrange access; do not send key codes or sensitive entry credentials through the form.
How is the quotation worked out?
The quotation depends on the identified mechanism, suitable parts, door condition, access and agreed attendance time. Confirm any initial assessment charge and the scope of replacement before work starts.
Will access authorisation need to be checked?
Be ready to establish that you are entitled to arrange the work and identify the responsible occupier or manager where the property is shared.
Should I buy a replacement part before the visit?
A photograph may not establish the dimensions or mechanism version. Confirm compatibility before purchasing a part for the intended repair.
When can the work be arranged?
For door gearbox replacement, confirm current assessment and supply times for your postcode. A first visit, made-to-order materials and the completed work may have different dates.
Does completing this form send a booking?
The form prepares a summary and an email draft for your review. Send the draft from your email app or call the team; the details of any booking are agreed separately.
