The first factor affecting cost is the size of the area. Larger rooms require more materials and labour, naturally increasing the overall price. Ceilings, high walls, or areas with architectural features such as alcoves or coving take longer to complete, adding to the cost.
Wall and ceiling conditions also impact pricing. Surfaces with cracks, holes, damp patches, or uneven textures require extra preparation before skimming. Proper preparation ensures the plaster adheres correctly and produces a professional, long-lasting finish. Skipping preparation can lead to uneven surfaces or cracks in the finished work.
Material choice matters. Standard plaster is commonly used for skimming and is affordable, while specialist plaster or additives may be required for moisture-prone areas or premium finishes. High-quality materials ensure a smoother finish and reduce the likelihood of future repairs.
Labour costs vary depending on skill, experience, and location. Experienced plasterers work efficiently, achieving a flawless finish with minimal mess. Inexperienced tradespeople may require more time and may not produce the same consistent results, potentially leading to additional costs for corrections.
Access and logistics are also considerations. Difficult-to-reach areas, tight spaces, or high ceilings may require scaffolding or ladders, which can increase labour and equipment costs. Project timing can influence pricing as well, with urgent or weekend work often attracting a premium.
When obtaining quotes, request a detailed breakdown covering labour, materials, preparation, and cleanup. This ensures transparency and allows for a fair comparison of different plasterers. Understanding these factors helps homeowners budget effectively and hire a professional who delivers a smooth, durable, and visually appealing finish on walls and ceilings.
