Kosmos clings to the mountainside on the northern shore of the Hartbeespoort Dam, one of the steepest residential areas in the country, with houses terraced into the slope above the water.

Common plaster problems in Kosmos
Terraced housing on the steep mountainside above the northern shore of the dam.
The steepest ground of any area served
Kosmos is built into a mountainside, and that dominates everything about working here. Properties are terraced, retaining walls do structural work, scaffolding takes far longer to set safely, and materials are routinely carried the last stretch by hand because no vehicle can reach the wall. A job that would take two days on flat ground can take four here, and that is worth establishing at quoting stage rather than discovering on the first morning.
Steep dam-side sites and retaining walls
The ground around the dam falls away sharply, so most properties here are terraced and retaining walls are structural rather than decorative. Plaster on a retaining wall has water behind it permanently, and it fails quite differently from a free-standing wall — blistering, salt staining and patches pushing off under pressure rather than simply cracking. Drainage behind the wall is the actual repair; replastering without it repeats the failure within a season.
Water-side humidity and algae
Property close to the water sits in noticeably more humid conditions than the slopes above, and walls facing the dam stay damp far longer. Algae establishes readily on plaster there, and painting over growth does not kill it — it returns through the new coat. Treating the growth and dealing with what is feeding it comes before any recoating.
Weekend and absentee property
A great deal of the housing here belongs to Gauteng owners and stands empty midweek and through parts of the year. A leak or a burst pipe develops unseen and is found on arrival as a ceiling and wall-head repair rather than a small job. Where an owner is not local, agreeing access and progress reporting up front matters as much as agreeing the scope.
Access and scaffolding on a slope
Steep, terraced sites take considerably longer to scaffold safely, and materials frequently have to be carried the last stretch rather than driven to the wall. Both affect how long a job takes and are worth establishing before the quote rather than discovering on the day.
Reading the age of the property
Older hillside cottages carry the oldest fabric and are frequently the hardest to reach. Later development is conventional and contemporary with high finish expectations. Retaining and terracing structures span the full range and are usually the oldest built elements on a property.
Typical projects around Kosmos
Retaining wall repair, access-constrained exterior work and damp treatment.
- Retaining and terrace walls — water behind, structural role.
- Steep and unreachable elevations — access and scaffolding.
- Water-facing walls — humidity, algae, persistent damp.
- Weekend homes — absentee owners, damage found late.
Working in Kosmos
Access is the first thing established here, before materials or method. On a retaining wall the drainage is checked before the plaster is specified. Scaffolding time is quoted honestly rather than absorbed.
Seasons and scheduling
North West runs on summer rainfall — storms from about October to March, usually heavy and short. The dry winter suits exterior work well: days are warm and settled, though nights get cold enough for frost on the higher ground. Roughly April to August is the practical window for exterior plastering, boundary walls and recoating, with summer work started early in the day. Interior work continues year round.
What helps when requesting a quote
Quotes are more accurate when the brief is specific. Give the street or property name rather than just the town, say whether the work is at ground or upper level, and send photographs of each affected surface in normal daylight. Where several rooms or several buildings are involved, list them separately. The quote checklist covers everything worth including.

Frequently asked questions
Do you charge extra to travel to Kosmos?
Location affects scheduling rather than the rate for the work itself. This area is within easy reach of the Gauteng base and is worked as a day trip, with several jobs in the area combined into one visit. 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.
Why does the damp keep coming back on a retaining wall?
Because a retaining wall has water behind it permanently, and replastering the face does nothing about that. The moisture pushes through and lifts the new work exactly as it lifted the old. The drainage behind the wall has to be dealt with first — after that the plaster holds. How long plaster takes to dry sets out realistic periods.
Do you handle outbuildings and boundary walls?
Yes, and boundary and retaining walls in particular. A retaining wall has water behind it permanently and fails differently from a free-standing one, so it is quoted differently too. See exterior plastering.
