Yes — a concrete footing sized to the wall's height and the soil. Retaining walls also need drainage behind them (weep holes, gravel backfill) or water pressure will crack or topple them. Most retaining-wall failures trace to missing drainage, not weak bricks.

Stepped cracks along mortar joints usually mean foundation movement; vertical cracks through bricks suggest thermal movement or missing expansion joints; horizontal cracking on retaining walls means soil pressure. Small hairline cracks can be monitored, but widening or stepped cracks deserve a structural opinion before cosmetic repair.

Usually, with effort — reclaimed bricks, brick-matching services and tinted mortars get close. An exact match matters most on street-facing walls; ask to see a sample panel before committing, since a bad match is permanent and obvious.

Bricklayers price per thousand bricks laid, per square metre of wall, or by day rate. The total depends on brick type, wall thickness (single or double skin), height and access. Foundations, damp-proof courses, copings and scaffold are separate line items that quotes must state.

A skilled bricklayer lays roughly 300-600 standard bricks a day on straightforward wall runs — fewer on detailed work, arches, or restoration. That is why fiddly small jobs cost more per brick than long straight walls.

Only if it is non-structural, and even then partition demolition/erection may need a registered minor works contractor. Structural walls need an Authorized Person's assessment and Buildings Department approval — never take a contractor's word alone that a wall is non-structural.
