Door hanging
Plain English. Practical detail. UK context.
Door hanging is fitting a suitable door leaf and associated hardware into an appropriate frame or opening so the assembly works as intended. The job can involve measurement, adjustment, hinges, latches and finishing. Ordinary internal, external and fire-resisting doors need different specifications and cannot be treated as interchangeable carpentry tasks.

Survey the opening and intended use
Check frame condition, dimensions, swing, floor finishes and hardware before ordering or cutting. An opening may be out of square or affected by movement; trimming the leaf does not repair every frame defect. Homeowners should state privacy, access, appearance and any performance needs. Trainees should identify the finished floor reference and clearances from the actual product rather than use an early rough-opening dimension. A door chosen only by nominal size may not have the adjustment allowance or hardware compatibility needed for the site.
The assembly includes hardware and support
Hinges, fixings, latch or lock, frame and any closer must suit the leaf, duty and specification. Weight and frequency of use affect selection. A long screw is not an automatic cure for a damaged or unsuitable frame. Product instructions determine permitted alterations and fitting details. The installer should protect completed finishes and coordinate handles or stops with nearby walls and fittings. A trainee needs instruction in accurate setting out, safe cutting and tool use, not only a demonstration of how to make the door close once.
Special doors require their own evidence
A fire-resisting door is an assembly with specified components and installation conditions. External doors can have weather, thermal and security requirements. England's Approved Documents provide relevant building context, with different national guidance elsewhere. Do not trim, glaze or fit hardware to a safety-critical product on the assumption that ordinary internal-door habits apply. The applicable product and performance evidence must be checked. HSE woodworking guidance is relevant to dust and machinery. A trainee should refer uncertainty rather than alter a certified component until it looks like the customer's preferred style.
A homeowner scope and final check
Agree leaf, frame repairs, ironmongery, finish, disposal and making good. Clarify whether painting, sealing edges and adjustment after other building work are included. Prices and outcomes vary from job to job, so compare written, itemised quotations rather than relying on a typical figure. Tradespeople should check the agreed operation, hardware and required performance details and leave relevant records. Homeowners should understand normal use and maintenance, including not defeating required closers or safety functions. A visually even gap alone does not demonstrate the complete door assembly is suitable or properly installed.
Frequently asked questions
Can any new door be trimmed to fit any old frame?
No. Check product allowances, performance requirements and the condition and suitability of the frame.
Is fire-door fitting identical to ordinary internal-door work?
No. The specified assembly, components, evidence and installation conditions must be followed.
