Repair or Replace?
In many cases, damaged plaster can be repaired without removing the entire wall or ceiling. The right approach depends on the cause of the damage, how secure the surrounding plaster is and the condition of the existing substrate.
Where sections are loose, badly deteriorated or affected by repeated movement or moisture, partial removal and replacement may provide a better long-term result.
We can assess the existing area and explain the practical repair options before the work begins.

Older Melbourne Homes
Many Melbourne homes contain older solid plaster, horsehair plaster, lath-and-plaster ceilings or previous repairs completed over many decades.
Older plaster can behave differently from modern plasterboard. Some areas may be suitable for repair, while loose or deteriorated sections may need to be removed and replaced.
RSG Plastering has extensive experience working with existing walls and ceilings and can recommend a practical approach based on the condition of the property.
