Internal corners, external corners and returns affect the cutting and joining plan. Rooms are not assumed perfectly square from a sketch. The aim is suitable ordinary decorative joints, with any existing wall irregularity discussed before promising a flawless straight line.
Show the finished floor and any planned change to flooring. The new skirting needs an agreed position at that junction. Decorative trim is not a way to conceal unresolved floor movement, and flooring alteration is not automatically part of a skirting replacement quote.
Old adhesive, nails and paint can affect removal and surrounding finishes. Show the condition before work is agreed. Some local making-good may need separate scope; replacing a run should not be sold as guaranteed damage-free removal from every existing wall.
Remove the agreed decorative runs, fit compatible replacement skirting with suitable joints and fixings, and prepare the agreed finish. Scope limits: Complete ordinary decorative runs only. No structural wall work, hazardous materials, concealed-service alterations or repair of underlying floor movement.
