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.
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.
Clarify filling, preparation and whether painting is included. Factory-primed material may still need finishing after installation. A fitted run and a fully decorated room are different outcomes, so the quote should identify who completes each stage.
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.
