Alexandra sits between Sandton and Marlboro and is one of the oldest townships in Johannesburg, established in 1912. It is also among the most densely built areas in the province, with original housing, decades of owner extension and a very high proportion of backyard rental accommodation packed onto small stands.

Common plaster problems in Alexandra
Very high density, older original housing with extensive backyard development.
Density and shared walls
Structures are frequently built right up to boundaries and against one another. Where a neighbouring building shares or abuts a wall, moisture and movement transfer between them, and a repair on one side may not hold unless the other is addressed.
Backyard rental units
Rooms built for rental are usually put up quickly and plastered thinly. They deteriorate faster than the main house and are the most frequent repair request on multi-unit stands.
Original housing at end of life
The oldest stock is now more than a century old in places. Original plaster on these has usually failed entirely and been patched many times over.
Extension junctions
Rooms and additions built at different times sit on different foundations and move independently of the original structure. The junction between them cracks repeatedly, and filling it without addressing the movement does not hold.
Exterior weathering
Exterior plaster takes the full Highveld cycle of intense summer storms and cold dry winters. That expansion and contraction opens hairline cracking, and once water gets behind the plaster the winter dry-out lifts it away from the wall.
Reading the age of the property
Alexandra spans more than a hundred years of building. The earliest stock carries original plaster long past its life. Extensions and backyard structures added from the 1970s onward vary enormously in quality — some are competently built, many were plastered thinly onto unprepared blockwork and have never held. Recent rebuilds are conventional modern construction.
Typical projects around Alexandra
Repair on older structures and replastering of thin work on backyard units.
- Old Alexandra — oldest housing, full replastering.
- Backyard rental units — thin plaster, frequent repair.
- Extended properties — multiple phases, junction cracking.
- Newer rebuilds — conventional finish work.
Working in Alexandra
Access is the defining practical constraint. Streets are narrow, stands are tight and there is often no space for material storage or on-site mixing, so deliveries have to be planned and material brought in smaller quantities. Being specific about the street and which structure on the stand needs attention makes a real difference to how accurately the job can be quoted and scheduled.
Scope and phasing
Where the whole property cannot be done at once, the sensible order is to deal with anything letting water in first, then walls showing structural failure, then cosmetic surfaces. Each return visit carries setup and protection time, so a phased job costs more in total than the same work done continuously — worth pricing both ways before deciding. Where several structures share a stand, listing them separately gives a far more accurate quote than treating the property as one job.
What helps when requesting a quote
Quotes are more accurate when the brief is specific. Give the street or section rather than just the area, say whether the work is at ground or upper level, and send photographs of each affected surface in normal daylight. Where several rooms are involved, list them separately — preparation differs between walls and ceilings even in the same house. The quote checklist covers everything worth including.

Frequently asked questions
Do you charge extra to travel to Alexandra?
Location affects scheduling rather than the rate for the work itself. What moves a quote is surface condition, preparation required, access and the finish expected. See plastering rates per m².
Can cracks just be filled?
Only where the cause has settled. A crack that keeps returning is a symptom rather than the problem — hairline vs structural cracks covers how to tell, and why cracks return covers recurrence after a repair.
Do you handle exterior and boundary walls?
Yes. Boundary walls and outbuildings are frequently the worst-affected plaster on a property, and exterior repair is routine work in Alexandra. See exterior plastering.
How soon can the work be painted?
Fresh plaster needs to cure before decorating, and rushing it is the most common cause of paint failing later. How long plaster takes to dry sets out realistic periods.
