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.
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.
Skirting lengths need a practical delivery and handling route. Mention stairs, narrow halls and room access before purchasing. The final run measurement alone does not show whether a long board can be brought into the workspace without additional joints or handling constraints.
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.
