    services for customers in Darlington and the surrounding area.

    The service is represented as an assessment-led process in which the
    rug's fibres, construction, condition and visible staining are considered
    before a suitable cleaning approach is selected.

    Professional cleaning may remove accumulated soil, reduce everyday
    residues and improve the rug's general appearance, but results remain
    dependent on the individual rug and complete stain removal is not
    guaranteed.

    Customers should be helped to understand the proposed method, likely
    drying considerations, handling arrangements, quotation scope, payment
    terms and any optional treatments before confirming the service."
