In depth

Understand the property decision before choosing.

Clearance, diagnosis and repair is part of maintenance and repairs and groups decisions that should be assessed together rather than split into disconnected searches.

Use the child pages to compare scope, property fit, timing, access, cost drivers, professional boundaries and the exact services or goods available.

The route is narrowed using property type, occupancy or operating use, existing records, access, urgency, specification and the responsibilities of owners, occupiers, landlords, managers and appointed professionals.

At this level, cost depends on the child route selected, the condition and type of property, scale, access, timing, specification and whether qualified or specialist attendance is required.

The guidance is supported by Citizens Advice, Ofwat, National Association of Drainage Contractors, Ministry of Housing, Communities and Local Government. Source links and review dates are shown on the page so customers can distinguish general Mayfair guidance from statutory, professional or regulator information.

Mayfair keeps the selected property-service context in the Property AI handoff, including the exact route and any location chosen, so the conversation begins here rather than starting again.

A simpler way to start

Start with the symptom, not the trade.
