Doorsets & frames
Door leaves, linings and frames fitted, adjusted and checked for consistent gaps and reliable operation.
Commercial joinery
Site installation of doorsets, ironmongery, architraves, skirtings, trims, fitted elements, access panels and specialist timber details across London and the UK.

Installation and finishing
I&O Construction provides site installation of commercial joinery and specialist interior details for fit-out projects across London and the UK.
Our role is installation and finishing rather than manufacture. We work from coordinated drawings, door and ironmongery schedules, setting-out information and project-specific details, with close attention to reveals, shadow gaps, hardware positions, movement, protection and interfaces with adjacent finishes.
Our joinery capability complements our acoustic work, allowing connected elements such as slatted media walls, doors within acoustic elevations, patresses, trims and access details to be coordinated as one practical installation package.
Door leaves, linings and frames fitted, adjusted and checked for consistent gaps and reliable operation.
Hinges, locks, closers, handles, push plates, stops and associated hardware installed to schedules.
Measured joints, controlled lines and careful interfaces with finished walls and floor surfaces.
Desks, counters, media surrounds, wall panels and project-specific joinery components installed on site.
Coordinated access and concealed supports for screens, cameras, speakers and building services.
Linear timber features and trims aligned with ceilings, walls, media equipment and acoustic finishes.



Installation approach
Drawings, schedules, hardware, substrates, openings, tolerances and interface responsibilities.
Confirm datums, fixing grounds, materials, protection, access and the installation sequence.
Set, fix, adjust and coordinate joinery components with surrounding finished surfaces.
Check gaps, operation, alignment, hardware, protection and final outstanding items.
Project example
Our project work includes detailed joinery installation where doors, timber linings, fitted elements and adjacent acoustic finishes must read as one interior.
