How to choose a good plasterer in London
Two plasterers visit the same room. One suggests a skim; the other says the wall needs more work first. How do you decide? Start with the reasons behind the quote, then look for evidence that they can do the job they’re proposing.
Six checks that tell you more than a sales pitch
You don’t have to know how to plaster a wall to choose someone to do it. You do need a clear picture of their experience, their proposed work and the arrangements for your home.
Ask for a job that looks like yours
A neat new-build wall won’t tell you much about repairing an older ceiling. Ask for examples of the type of work you need: a room skim, patch repairs, plasterboarding or exterior rendering. A useful follow-up is, “What was the surface like before you started?”
Listen to the questions they ask
What’s on the wall now? Has it been repaired before? What finish are you expecting? Someone who asks about the background has more to work with than someone pricing a room from its name alone. If a detail is uncertain, ask how they’ll check it.
Get the preparation explained
Ask which areas need attention before the finish goes on, and why. If one quote includes repairs or boarding and another doesn’t, have both plasterers explain their approach. You’re looking for a reason tied to your property, rather than a list of unfamiliar product names.
Look beyond the best photograph
Ask to see wider views as well as close-ups, including corners and the edges around openings. Read reviews for details of the work, communication and how any problems were handled. Where possible, ask whether a previous customer with a similar job is happy to provide a reference.
Check who you’re booking
Confirm the business name, contact details and who will actually carry out the work. Ask about relevant insurance. If a trade membership or accreditation influences your choice, check it with the organisation named rather than relying only on a logo.
Talk through a normal working day
Agree access, working hours, room clearance, protection and cleanup. In a London flat, discuss stairs or lift access, parking arrangements and any building restrictions. These practical details deserve a place in the conversation before a start date is set.
What are you getting for the price?
“Plaster bedroom” leaves a lot open to interpretation. A useful written quote identifies the surfaces, the preparation and the finish. Use the checks below to find gaps before choosing.
| Item | What to look for | Question to ask |
|---|---|---|
| Surfaces | Named rooms, walls and ceilings; areas left out. | “Does this cover the ceiling and window reveals too?” |
| Preparation | Repairs, removal of loose material, boarding or other agreed work. | “Which preparation is included in this price?” |
| Materials | Whether labour and materials are both covered. | “Is there anything I need to buy separately?” |
| Protection and waste | Who clears the room, protects surrounding areas and removes waste. | “What will I need to do before and after the job?” |
| Finish | The intended finish and whether decorating is separate. | “What work will the decorator need to allow for?” |
| Price and payment | The total, any applicable VAT, payment stages and exclusions. | “What could change the price, and how would we agree it?” |
| Timing | The proposed start, expected time on site and dependencies. | “What needs to happen before you can start?” |
A simple example
One quote covers skimming four walls. Another includes the ceiling, repairs around a doorway and waste removal. The totals alone won’t tell you which is better value. First ask each plasterer to price the same agreed scope.
For early budgeting, our plastering cost calculator is a starting point. Use a job-specific quotation to decide what you’re actually booking.
Check the edges as well as the middle
When you look at previous work or walk through your own completed room, take in the whole surface. Then look more closely at corners, window reveals and the lines around doorways. Ask about obvious ridges, rough patches or untidy junctions.
View the room from more than one position and in its usual lighting. A single photograph is useful evidence, but it can’t show everything about a wall or ceiling.
Make sure you and the plasterer mean the same thing by the agreed finish. If the job is a thin skim over an existing wall, ask beforehand whether straightening the wall is part of the work.
Ask why that method suits this wall
A painted wall, new plasterboard and an older repaired surface can raise different questions. You don’t need to prescribe the product; ask the plasterer to explain the choice and any preparation it requires.
For example, British Gypsum says plastering over paint depends on both the paint and the underlying surface being in very good condition. That’s a more useful discussion than simply asking whether any painted wall can be skimmed.

Don’t leave these questions until work starts
An unclear answer doesn’t automatically make someone a poor plasterer. Give them a chance to explain. If the important details stay unclear, take more time before booking.
The quote is only a total
Ask for the work and exclusions in writing. You need to know what the number covers.
The proposed repair has no explanation
If a problem keeps returning, ask what has been considered before agreeing to cover it again.
You’re pushed to decide on the spot
Take time to read the scope and payment arrangements. A date being available doesn’t answer questions about the work.
Changes are left to “sort out later”
Agree how extra work will be discussed and priced. Don’t wait until the original scope has already changed.
Could you explain the job back to them?
Before you accept, you should be able to say which surfaces are being worked on, what preparation is included, what it costs and what remains for you or another trade. If you can’t, there’s still a useful question to ask.
The questions that often come next
How many plastering quotes should I get?
If practical, get three written quotations for the same work. Give each plasterer the same brief, then compare the proposed preparation, included surfaces and exclusions. A third quote is less useful if it describes a different job.
Is a higher price a sign of better plastering?
Price alone can’t tell you how well a job will be done. Ask what explains the difference: extra preparation, more surfaces, materials or access arrangements. Then weigh that against relevant work examples and how clearly the scope has been explained.
Can I judge a plasterer from photos alone?
Photos help you shortlist, but they don’t show how a job was prepared or managed. Ask what each project involved, look for examples similar to yours and use reviews or references to fill in the gaps.
Should I ask about a deposit?
Yes. Ask whether one is required, what it covers, when any later payments are due and how payments will be recorded. Make sure the arrangements are written down and understood before you commit.
What if extra work is uncovered after starting?
Ask how the plasterer handles that situation before the job begins. If the scope changes, request an explanation and agree the additional work, cost and effect on timing in writing before it goes ahead.
What should I ask at the end of the job?
Walk through the agreed areas together and raise anything you’re unsure about. Ask for aftercare and decorating guidance for the materials used, and confirm who to contact if a question comes up later.
