Common Causes of Cracked Plaster and What Homeowners Can Do

Cracked plaster is a common problem in older and newer properties. While some cracks may be relatively minor, others can indicate that the surface requires more extensive attention.

Small cracks can sometimes develop as materials move naturally over time. Changes in temperature, movement within a building, previous repairs and ageing plaster can all contribute to cracking.

The correct repair depends on the size, location and condition of the damaged area. Small localised defects may only require preparation and patch repair, while walls with widespread damage may benefit from replastering or skimming.

Before repairing cracks, loose material should be removed and the surface properly prepared. Simply covering a damaged area without addressing the underlying problem can result in the crack returning.

Homeowners in London looking for professional assistance can contact London Plastering Service for plaster repairs, skimming and replastering.

A properly prepared surface provides a much better foundation for painting and decorating.
