Common plaster problems in Theunissen
A farming town on the southern edge of the mining district.
Between two districts, taking dust from both
Theunissen sits where farming country meets the goldfields, and exterior surfaces here carry organic grain dust and drifting mineral dust in varying proportions. Both hold moisture and prevent coatings keying, and both need washing off properly rather than being painted over.
Ground movement at the district margin
Mining on this scale required enormous volumes of groundwater to be pumped out over decades, and taking water out of the ground changes how that ground behaves. As operations have wound down in places and pumping regimes have changed, water levels recover, and ground that moved one way while it was being dewatered can move again as it refills. This is slow and it is not a crisis, but it does mean ground movement in this district is not necessarily finished. A crack that keeps widening after a proper repair is worth having looked at rather than filled a third time.
Older town fabric at end of life
The older layer of buildings has generally reached the point where original plaster is not sound, and patching material in that state is money spent twice.
River-district damp
Ground near the Sand holds water and older construction shows a persistent low band of failing plaster with salts pushing through the finish, which is also where frost concentrates.
Farm buildings across the district
Sheds, stores and handling structures on the surrounding farms take heavy use and minimal maintenance, quoted to durability rather than finish and scheduled around the farming year.
Reading the age of the property
An older town core with plaster generally at end of life, some mining-era building, and a substantial agricultural stock across the district.
Typical projects around Theunissen
Dust from two districts, ground movement, river damp and farm buildings.
- Grain and mineral dust — wash-down before any recoating.
- Ground movement — assessed rather than refilled.
- River damp — low band with salting, then frost.
- Farm buildings — durability, seasonal timing.
Working in Theunissen
Where two dust sources are present the wash-down takes longer than owners expect, and skipping it is why so much repainting in this district fails early. Ground levels get checked before low-level repairs.
Seasons and scheduling
The Free State runs on summer rainfall — thunderstorms from about October to March, usually heavy and short. The dry winter looks ideal for exterior work, and the daytime hours genuinely are, but this is among the coldest inhabited parts of the country and frost is the binding constraint rather than rain. Plaster that has not set before the overnight minimum arrives can be damaged in a single night. Roughly March to May and August to October give the most reliable exterior conditions — warm enough to cure, past the storms and clear of the hardest frost. Midwinter exterior work is started late in the morning and stopped early enough for the surface to set. 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 Theunissen?
Location affects scheduling rather than the rate for the work itself. The goldfields are a long run from the Gauteng base, so work here is planned as a block rather than a single call-out, with several jobs across the district combined into one visit. Notice is what makes that efficient. 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 plaster flake off in patches rather than crack?
Frost is the usual answer. Water that has soaked into the outer few millimetres of plaster expands as it freezes overnight and contracts again by the afternoon, and repeated often enough that cycle pushes the face of the plaster off in flakes and patches rather than cracking it. It shows first where walls stay damp longest — below a leaking gutter, behind a downpipe, at the base of a wall taking splash-back, on the south elevation that gets no winter sun. Fixing the plaster without fixing the water simply restarts the clock. See water damaged plaster repair.
Do you handle outbuildings and boundary walls?
Yes, and boundary walls in particular. They take sun, frost and weather on both faces with nothing sheltering them, and hold no interior warmth at all overnight, so they freeze harder than the house does. They are commonly the worst-affected plaster on a property here. See exterior plastering.
