Cornice installation & repair Roodepoort

The most common are polystyrene and polyurethane (lightweight, easy to install), gypsum plaster (traditional and heavier) and timber. Polyurethane gives crisp detail and holds up well; plaster suits older homes where matching an existing profile matters.

Expect roughly R60 to R150 per running metre for supply and fitting of standard polystyrene or polyurethane cornice in Roodepoort. Plaster and decorative profiles cost more. A typical bedroom needs 14 to 18 metres, so budget a few thousand rand for an average room.

Small cracks and gaps can be filled and repainted. If a section has come loose, crumbled or been broken, it is cleaner to cut out that length and replace it with a matching profile, then blend the join with filler.

Ceilings and walls move slightly with temperature and roof timber movement, and rigid filler at the joint cracks. Fitting with a flexible adhesive and finishing with a paintable flexible sealant rather than hard filler prevents most of it.

A standard room with simple corners takes half a day to fit, plus time for the adhesive to set and for the joints to be filled and painted. Rooms with many corners or ornate profiles take longer because every mitre has to be cut precisely.
