Welkom was laid out from scratch in the late 1940s to serve the newly opened Free State goldfields, one of very few South African cities designed as a whole before it was built, and still the commercial centre of the district.

Common plaster problems in Welkom
A wholly planned city built over one concentrated era, now ageing together.
A city that was designed, then built, all at once
Welkom is unusual and it matters for this work. Most towns accumulate over a century and their buildings fail one at a time. Welkom was planned as a complete city and built out over a short, concentrated period, which means its housing, its commercial stock and its infrastructure are effectively the same age. The original plaster is of one broad specification and it reaches each stage of its life across the whole city at once. Whole streets need the same thing at the same time, and that is the single most useful fact about working here.
Ground that has been dewatered, and is refilling
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.
Deep-level seismicity
Deep mining produces tremors, and these reopen cracks that were filled rather than cut out and keyed. Distinguishing a crack that is being worked by ground movement from ordinary thermal cracking is the first step here, because they need entirely different repairs and one of them cannot be solved by plastering.
Mine dust and coating adhesion
Workings, dumps and haul routes put fine mineral dust onto exterior surfaces. It settles into the finish, holds moisture against the wall and stops paint keying, so washing down to a clean, sound surface before recoating is preparation rather than an extra.
Company and hostel accommodation
The mines brought very substantial company housing and converted hostel accommodation, maintained in blocks rather than singly, specified for durability and turnaround rather than fine finish, and carrying decades of hard use.
Reading the age of the property
One dominant building era from the late 1940s onward, unusually uniform, with later infill and some recent development on the edges. Nothing here is old enough to raise compatible-repair questions.
Typical projects around Welkom
Whole-street plaster renewal, ground-movement cracking, dust preparation and block housing.
- Uniform original stock — one specification, one failure timetable.
- Ground movement — assessed before repair, not filled repeatedly.
- Mine dust — wash-down before any recoating.
- Company and hostel housing — block work, hard wear.
Working in Welkom
Because the stock is so uniform, several properties can be assessed and scheduled together and that is much the most economical way to work. Where a crack has been repaired before and returned, establishing whether the ground is still moving comes before specifying anything further.
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 Welkom?
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.
