Cost: door and corridor widening
Price each opening according to its condition: door assembly, possible masonry, services, threshold and finishes. Nominal door width does not establish usable clearance. Without assessing walls and the route, a per-door price or standard duration cannot reliably compare solutions.
Editorial update on 18 September 2026
Request an item for each opening
Label each door on the plan with finished dimensions, supplied assembly, hardware and finish. Distinguish replacement within an existing opening from enlargement. Door counts alone conceal differences in the supporting walls.
Separate surrounding work
Itemise any study, protection, removal, wall alteration, service relocation and disposal. Add flooring connections, skirtings and paint on both sides. Specify treated areas instead of a general finishes-included statement.
Plan occupancy during work
Ask which rooms will be unavailable, the sequence of openings and what determines return to use. Compare outstanding items and acceptance of the finished passage. No per-door duration is established without knowing the site.

Frequently asked questions
Must every door be widened?
Start with the route actually needed and its continuity; the number depends on the home and use.
Does a 90 cm door give 90 cm clearance?
Request finished clear width in use, not just a commercial size.
Can every threshold be removed?
Assess its function and floor or waterproofing connections before designing the change.
Does a sliding door solve limited space?
It changes swing requirements, but pocket or parking space, grip and operation still need assessment.
