Drywall and Plasterboard Repair Services

Plasterboard walls and ceilings are standard in UK homes built from the 1970s onward, and damage — from accidental impacts, door handle strikes, water ingress, or building work exposing concealed services — is common. Knowing what kind of repair is needed, which trade to call, and what a properly finished result looks like helps you scope the job accurately and budget without guesswork.

Key points

• Standard plasterboard used in UK homes is most commonly 12.5mm thick; moisture-resistant board (often pink or green-faced) is specified for bathrooms and kitchens under BS EN 520.
• Small holes up to approximately 50mm across can usually be filled using a repair patch and jointing compound; larger sections require new board, taped joints, and a skim coat.
• Moisture-damaged plasterboard should be replaced rather than patched — board that has been wet loses its core integrity and may harbour mould behind the facing paper.
• Most plasterboard repair work does not require building regulations consent, but work affecting a fire-rated partition or structural element may need approval from your local building control authority.
• UK plasterers carrying out dry-lining work may hold an NVQ in Plastering (Dry Lining) Level 2 or Level 3 (CITB-accredited), a useful indicator of competence when selecting a contractor.

What types of plasterboard damage are common in UK homes?

Damage falls into a few clear categories. Understanding which type you have helps you scope the job accurately before requesting quotes.

DIY or hire a professional?

Not all plasterboard repairs need a tradesperson — but the right choice depends on hole size, desired finish quality, and whether there is an underlying cause to investigate.

Choose professional help if:

• The damage is larger than roughly 150mm across.
• The damaged area is in a ceiling.
• You suspect water ingress as the underlying cause — the source must be identified and resolved before any board replacement.
• A skimmed finish is needed rather than a filled-and-sanded surface.
• The wall is in a high-visibility location such as a living room, hallway, or open-plan space.
• The board forms part of a fire-rated partition in a flat, conversion, or HMO — do not disturb without checking the specification.

DIY may be appropriate if:

• The hole is small (under 50mm) and a filled, lightly sanded finish is acceptable.
• You have experience with jointing compound and understand the drying times involved.
• There is no risk of hidden cables or pipes behind the board — always use a cable and pipe detector before cutting into any wall.
• The area is low-visibility, such as inside a cupboard or utility room.

Finding a qualified plasterboard repair contractor

For most repair work you need a plasterer with dry-lining experience, or a qualified dryliner who also provides finishing and skimming services. Useful indicators of competence include:

• NVQ in Plastering (Dry Lining) Level 2 or Level 3 — awarded through CITB-accredited assessment centres.
• TrustMark registration — the government-endorsed quality scheme for home improvement tradespeople, covering plastering and dry-lining work.
• Federation of Plastering and Drywall Contractors (FPDC) membership — the recognised trade body for the sector.
• References from comparable repair jobs with photographs of completed skims in similar properties.

For jobs involving fire-rated partitions — common in purpose-built flats, loft conversions, and properties used as HMOs — confirm that the contractor understands the fire performance specification of the existing board and can match it correctly.

Homeowner checklist before work starts

Use this checklist to prepare for a plasterboard repair visit and avoid common delays:

• Identify and resolve any source of moisture before instructing repair work.
  
• Locate and mark electrical sockets, switches, and light fittings on or near the damaged wall.
  
• Check whether the wall or ceiling forms part of a fire-rated construction (check your lease or building information if the property is a flat).
  
• Clear the work area and protect flooring — skim plastering produces fine dust.
  
• Decide on the finish level required: filled and sanded (suitable for wallpaper), or skimmed and ready to paint.
  
• Confirm access requirements — parking, lift access in flats, agreed working hours in leasehold properties.
  
• Agree in writing whether decoration (priming, painting) is included in the quote or is a separate phase.
  
• Ask the quote to specify board type (standard, moisture-resistant, or fire-rated) so you can confirm it matches the existing construction.
  

When to get professional help

Call a professional rather than attempting DIY repair when:

• Damp or discolouration around the damage suggests an active or historic water leak — the source must be found and fixed first.
• The damage is on a ceiling above a bathroom, kitchen, or shower room where moisture levels are elevated.
• The plasterboard forms part of a fire-rated partition in a flat, conversion, or HMO.
• A hollow sound covers a large area, suggesting a dot-and-dab board bay may be separating from the masonry behind.
• Mould is visible on or behind the facing paper of the board.

Frequently asked questions

What is the difference between plasterboard and drywall in the UK?

The terms refer to the same product: a gypsum plaster core faced on both sides with paper. Plasterboard is the standard UK trade term; drywall is the American term also used informally in the UK. Products from British Gypsum (Gyproc), Knauf, and others are broadly interchangeable at equivalent grades.

Can plasterboard be repaired without re-skimming the whole wall?

Yes, for small holes a patch and jointing compound, once primed and painted, can be blended well enough to be barely visible. For larger areas, a full skim of the wall or ceiling gives a more consistent finish, as spot repairs can leave visible ridges under raking light or sheen paint.

How long does a plasterboard repair take to dry before painting?

Jointing compound typically takes 24 hours per coat to dry at normal room temperatures (around 20°C). A skim coat of finishing plaster needs a minimum of 24–48 hours before priming and painting, and longer in cool or humid conditions. Painting too early can cause efflorescence and poor adhesion.

Do I need building regulations approval for plasterboard repairs?

Straightforward repairs to an existing wall or ceiling do not require building regulations consent. If the work affects a fire-rated partition, a structural element, or involves notifiable electrical alterations, separate approvals may apply. If in doubt, check with your local building control authority before proceeding.

How much does plasterboard repair cost in the UK?

Small patch repairs typically range from £80–£200 including labour and materials. Larger section replacements with a skim finish may cost £200–£600 or more depending on area and access. Ceiling repairs generally cost more than wall repairs. Obtain at least two or three written quotes before committing. (Indicative UK costs, last reviewed 2026-05-11.)
