Bricklaying & Masonry in Kai Tak

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.

Rules vary, but retaining walls above roughly 0.6-1m, boundary walls above fence-height limits, and anything structural typically need approval and sometimes an engineer's design. A bricklayer in Kai Tak should know the local threshold — if they say approval never applies, get a second opinion.

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.

Repointing — grinding out failed mortar joints and refilling them — is priced per square metre and needed when mortar crumbles, washes out, or lets damp through. It is far cheaper than rebuilding, but matching the mortar mix and joint style to the original is what separates good work from patchwork.

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.

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.

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.
