Cracking Is the Plumstead Problem
Plumstead is mostly single-storey family housing from the 1940s through the 1960s, and a very high proportion of it has been extended at some point - an enclosed stoep, a converted garage, a room added on the back. That is where the paint problems start.
An extension built decades after the original house sits on its own foundation and moves independently. The junction between old and new opens up as a vertical crack, usually running floor to roof, and it reopens every summer as the ground dries out and closes again in winter. Filling it and painting over it looks fine for about eight months. Then the crack telegraphs straight back through the new paint, and people conclude the paint was bad when the problem was the preparation.
What Painting Costs in Plumstead
These are 2026 ranges for prepped, two-coat work in Plumstead, not quotes. The swing factor is cracking. Metres of crack to rout and mesh, and how many steel windows need stripping, will move a Plumstead quote by R10,000 either way on houses that look identical from the street.
Crack work is normally R3,000 to R9,000 on a typical Plumstead house. If a quote does not have a separate line for it, the painter is either planning to skim over the cracks or intends to come back to you for more money once the scaffolding is up.
When to Paint in Plumstead
October to April for exteriors, with February to April the best of it. Plumstead is on the drier side of the Southern Suburbs so the season is reasonably long and you have some flexibility.
There is a specific reason to prefer late summer here. Crack movement is seasonal: cracks open widest in the dry months as the ground shrinks. Repairing them at their widest, in February or March, means the filler is not later forced apart when the crack expands further. Repair a crack in October at its narrowest and it will split the repair by the following autumn.
Steel window work is best in dry, still weather - the rust converter and the enamel both need clean, dry conditions and enamel picks up dust badly on a windy day. February and March again.
Getting Cracks and Steel Windows Right
- Structural cracks are cut out, not filled over. The crack is routed into a V, dust blown out, then filled with a flexible polyurethane or acrylic crack filler and bedded with fibreglass mesh so the repair can move with the wall instead of splitting.
- High-build elastomerics: Plascon Micatex or a Dulux Weathershield textured system stretch across hairline crazing and hide minor cracking that a smooth paint would show straight through. On a house with widespread fine cracking this upgrade pays for itself.
- Elastomeric is not a structural fix. It bridges hairline movement. A crack you can fit a coin into is moving too much for any coating and needs the routing and mesh treatment first.
- Steel window frames: wire-brush or mechanically strip to bare metal, apply a rust converter, then a metal primer, then two coats of enamel. Plascon Velvaglo Water-Based or a Duram enamel both work well.
- Do not paint over rust bloom on steel. It carries on corroding under the film, and the section that lifts next time will be bigger than the one you painted over.
Reading the Cracks Before You Quote
- Hairline crazing spread evenly across a wall is surface shrinkage in the plaster - cosmetic, and a high-build coating covers it
- A single vertical crack at the junction of an extension is movement, and it needs routing, mesh and a flexible filler
- Stepped cracking following the mortar joints in a diagonal line means foundation movement - get a structural opinion before spending on paint
- Cracks wider at the top than the bottom, or vice versa, indicate active settlement rather than a stable old crack
- Mark a few cracks with a pencil line and date them. If they move over a season, you have a structural issue rather than a painting one
- Never let a painter fill a crack without cutting it out first - filler smeared into a closed crack has nothing to grip and pops out
