It is preferable if chuck’s of your already existing plaster is coming off then you should first patch it or take of the existing plaster so that cracks do not appear again after replastering.

How much it costs to plaster a room?

The costs of plastering a room is not fixed as a lot of factors guide it. The prices vary based on materials used for the plastering, the size of the room, time and the kind of plaster. I will provide an estimated costs of plastering for the various kinds of plaster. Also, when plasterers price up a job they will consider the level of access to the area they are plastering. If you have a job that is on a steep ladder or in a tight space then it is likely that they will charge you more for this. The average price of bonding, multi-finish plaster sand / cement and other plastering material has increased significantly in 2021-2022 so you should expect plasterers to adjust their prices accordingly.

cost of plastering - money picture

Skimming costs relatively cheaper than the others. For small sized rooms in london, plasterers usually charge around £450 – £600. For medium sized suite, it costs about  £600 – £800 and for large sized suite it costs about £800 and above. The prices also differ based on complexity, travel distance and time involved.

So plastering of small en-suite costs approximately £800 plus whereas medium and large sized en-suite rooms costs £1,500 – £2,000 plus. If you are considering plastering only ceilings you should expect to pay between £450 and £700 based on the size of the room. 

The costs of labour for dry lining for ceiling  is about £250-£350 , whereas the costs of materials should be about £50-£100 per ceiling. For medium rooms, it costs about £300-£500 for labour and £100 for materials per room. It will obviously cost much more for dry lining  a whole house. 

In conclusion the cost of plaster depends on the size of the area needing plastering. So if you’re looking to plaster a large area, then it’s going to be more expensive than if you’re doing a small patch or filler job on a smaller scale. It’s also important to consider the type of plaster you need. If you want to paint a wall with texture and detail, then a fine grade of plaster is going to work best for you.

Where Your Money Goes –Work Manship vs. Materials Costs

Plasterers measure up the job and consider relevant factors before judging how much stuff will be needed and how much time will be used . Plastering is a job that must be done meticulously and most plasterers charge a fair price for this .When it comes to plastering  a ceiling it can be very pain stacking because the plasterer works above his head. Thus putting a lot of strain on his neck, shoulder and upper back hence the costs of plastering a single ceiling is more when taking into consideration the area alone.

On the other hand , the costs of materials is another thing, depending on the project you decide on . For example, if the project is a family house with cracks running through most walls then you will need to weigh the cost of additional material such as mash, fillers, bonding and the time involved in additional preparation work.

However, the key difference between these two when comparing them is where and at what stage they are done at.
