How Much Does it Cost to Plaster a House?

Cost of Plastering Your Home

Cost is usually considered by the room, unlike a house rendering cost, which is estimated by the m2, or square metre.

  • The cost to plaster a small room averages about £675 for new plaster (base layer plus skimming the surface with a second layer)
  • The cost to plaster a medium sized room averages £1000.
  • The cost to plaster a large room is about £1350 for the average, though plastering a very large room can run over £1500.

The cost to skim a room, which is to apply an additional layer of plaster to existing plaster in good condition, is £450 to £1000.

That’s an overview. Keep reading for additional information on the average cost to plaster a house, cost to skim a ceiling and much more.

Plastering vs Skimming

Plastering a room usually refers to starting from scratch and proceeding in one of two ways. First, by installing plasterboard, aka drylining, and then skimming it with a smooth top layer. Secondly, by wet plastering with one or two base layers before applying the skim coat.

Plastering is the right choice with new building or when the existing plaster is in such poor condition it is better to remove it and start fresh.

Skimming is technically one of the tasks in plastering – a subset of plastering, you might say. To skim a wall or ceiling is to apply just a single plaster coat, a skim coat, to an existing plaster wall.

A skim coat is acceptable when the underlying plaster is in good condition but has surface imperfections that would be seen even if covered with paint or wallpaper. Large cracks in the underlying plaster must be filled and sanded for best results when skimming existing plaster.

Plastering vs skimming, which is right for you?

Ask the various plasterers you speak to when getting quotes. They will suggest the best option after inspecting your walls and/or ceiling and should be able to clearly explain why the work they suggest is the right choice for your room or entire home. 

It might be a good idea to get quotes for both types of work, and then decide if you want to spend the extra to have old plaster removed and new plaster installed and covered with a skim coat.

Cost to Plaster a Whole House

Cost of Plastering Your Whole House

The cost to plaster a house per room varies because houses vary so much in size. Expect to pay £3600 to to £10,000 to plaster a house, with the average cost to plaster a 2 bedroom house being about £5800 and the cost to plaster a 3 bedroom house being £6400

In general, the average cost to plaster a house is about £785 per room, including ceilings. Small rooms might cost less than £600 whilst the largest rooms exceed £1500.

The larger the home – the more rooms it has – the lower the cost per room. This is because the plasterer is already on site with equipment and materials, so the more rooms plastered, the lower the cost per room based on economies of scale. The cost difference isn’t large, as you can see in our Cost to Plaster a House table.

All House Sizes £595 – £1,000 per room 5-10 days

Cost to Skim a Room

As noted, to skim a room means to apply a surface coat to existing plaster to give walls and ceilings a smooth finish. It is a cost-saving approach to putting a fresh look on old plaster that is in reasonably good condition. That is the key. 

However, if you choose this method as a shortcut in trying to make damaged, stained plaster look like new, it probably won’t work. 

The cost to skim a room is a third to half less than the cost to plaster a room. Putting on the skim coat requires the most expertise.

This table shows costs for adding a skim coat to rooms of various sizes.

Cost to Skim a Room in your home
Room / Project Size Costs Time to Complete Job
Skimming a Room    
Skim a Small Room £300 – £450 Up to 1 day
Skim a Medium Room £425 – £650 About 1 day
Skim a Large Room £600 – £1000 1-2 days

Factors Affecting the Cost of Plastering

Whether your cost estimates will be closer to £650 per room or £950 or more per room will largely be based on these factors. 

Room Size: Larger rooms cost more to plaster, but other factors might have a greater impact on the cost to plaster a room. 

The Specific Work Done: We’ve included costs for plastering from scratch, the cost to re-plaster and the cost to skim a room. If you’re building a home or extension, then, of course, you’ll be plastering from scratch. If you have existing plaster that you know is in terrible condition, then you’ll also be plastering – with removal costs included (see the next factor). When your not sure about the condition, it makes sense to get several cost estimates from reputable contractors to decide the proper scope of the project. There’s no need to pay for re-plastering, for example, if skimming the walls will be sufficient. 

The Condition of the Walls: When working in an older house, the walls might need repairs prior to adding plaster. This is true when skimming walls rather than re-plastering or installing new plaster. The more repair work required, the higher the cost of the project. 

Wall and Ceiling Height: Tall rooms cost more for two reasons – there is more wall to plaster, and reaching the top of high walls and reaching high ceilings takes more labour, time and equipment. Cost can rise significantly is scaffolding must be brought in for the purpose. While rare, hiring scaffolding to complete a plastering job is expensive. 

Room Complexity: When there are more than four corners and obstacles like shelving or a fireplace must be worked around, the cost to plaster a room can go up. 

The Cost of Removal and Disposal: The labour costs to tear out plaster, load it into a truck or bin and haul it away can really add up. If you know the old plaster must be removed, one option is to do the work yourself. If the project is large – your entire house – then hiring a skip for the disposal should be considered. 

Who You Hire: Qualified tradesmen with good experience might cost more than those with little experience. But the difference in outcomes can be very obvious. It makes sense to choose a plasterer with proven experience of doing the work properly the first time – and giving you plastered walls and ceilings you’ll be happy to live with for decades to come. 

Where you Live: As you likely know, costs are higher in London and the surrounding area than they are in other parts of the country.

Is Plastering a DIY Job?

Cost of Plastering FAQ

You might have one or more of these questions for this home improvement project

Q. How much do plasterers charge?

A. If they price a job by the hour, the cost is £33 to £55 per hour based on the type of work, the experience of the contractor and where you live. 

Q. What is the best time of year to have plastering work done?

A. Plaster dries best when the air is warm and dry – though not too dry. Summer is ideal, but plasterers are very busy in this season. During winter when you’re heating your home and the air is fairly dry can also be a good time, if you don’t mind the light odor of plaster in a closed-up home. 

Q. Can I plaster my own walls and ceilings?

A. Yes, but we recommend hiring a skilled, experienced plasterer when you want professional-quality results. Most homeowners don’t possess the skills to make the surfaces look as good as they want them to look. 

Q. What is the difference between plastering and skimming?

A. Plastering includes plasterboard or layers of plaster covered with a skim coat. Skimming includes just the final layer of plaster and is done when the existing plaster is in excellent condition – but just needs freshening. 

Hiring a Plasterer

It is considered good practice to get quotes from 3 plasterers, consider the experience of each, check their references and then choose a contractor you believe will do a good job at a fair price.
