If you are pricing up a plastering job, you will find quotes vary a lot, and it is not always obvious why. This guide breaks down what plastering a room typically costs in Liverpool and the wider North West, what pushes the price up or down, and how to compare quotes sensibly.
The biggest factor is whether you need a skim coat or a full replaster. Skimming means applying a thin finishing coat over existing sound plaster or fresh plasterboard, and it is the most common job in older Liverpool terraces and semis. For a small room such as a box bedroom, skimming the walls typically comes in around £150 to £300. A medium bedroom or average living room is usually £250 to £450, and a large lounge or open plan space can be £400 to £600 or more.
A full replaster, where the old plaster is stripped back and the wall is reboarded or rendered before skimming, costs considerably more because of the extra labour, materials and waste removal. Expect roughly £500 to £900 for a medium room, and upwards of £1,000 for larger rooms or where the walls are in poor condition. Ceilings are priced separately, usually £150 to £400 depending on size and whether the old ceiling needs overboarding. These are realistic ranges rather than fixed prices, and any decent plasterer will confirm a figure after seeing the room.
Two rooms of the same size can be quoted very differently, and there are usually good reasons for it. The condition of the existing walls matters most. Blown or hollow plaster, old wallpaper that has been painted over, or crumbling backing coats all add preparation time, and preparation is where much of the labour goes.
Access and layout play a part too. Stairwells and high ceilings need towers or staging, and rooms full of furniture take longer to protect and work around. In older properties around Liverpool, from Victorian terraces in Wavertree to 1930s semis in Crosby, it is common to uncover lath and plaster or damp issues once work starts, so a sensible quote may include a note about what happens if hidden problems appear.
A common mistake is paying for a full replaster when a skim would do, or the reverse, skimming over failing plaster that then cracks within a year. As a rough test, tap the wall. A dull, solid sound suggests the plaster is well bonded and a skim is fine. A hollow sound over large areas means the plaster has blown away from the wall and skimming over it is a false economy.
Dot and dab plasterboarding, where new boards are fixed over the old wall and then skimmed, is often a good middle ground for tired walls. It costs more than a skim but less than a full hack off and render, and it gives a flat, modern finish. If there is damp, that needs diagnosing and fixing before any plastering, otherwise the new finish will fail no matter how well it is applied.
When you gather quotes, make sure each one covers the same scope. One plasterer might include stripping wallpaper, PVA bonding, protecting floors and removing waste, while another quotes purely for the skim. The cheapest number is not always the cheapest job once extras appear.
Ask how long the work will take, what preparation is included, and how long to leave the plaster before painting. Fresh plaster in an average room usually needs several days to a week to dry fully, longer in winter, and it should be painted first with a watered down mist coat. A plasterer who explains this without being asked is usually one who takes the finish seriously.
