Height, thickness and shape affect the match with adjoining trim. Send a profile sample or product specification before ordering lengths. A close front-view resemblance may still leave a different projection at door surrounds or corners, so compatibility needs review.
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.
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.
