Party wall work is meant to be manageable and properly controlledābut when damage shows up, it can quickly become stressful. Even small cracks, lifted plaster, or staining can feel intrusive, and because the issue may affect two properties, it can also strain neighbour relationships.
This is exactly why party wall surveyors exist. Their role is to identify and manage risk, record the condition of the adjoining property, and put a clear framework in place so that any damage is dealt with fairly. The aim is straightforward: keep disputes to a minimum and make sure the adjoining owner is not left paying for repairs they didnāt cause.
What repair costs might a building owner face?
There isnāt a fixed price for āparty wall damageā because it depends on what has happened and how extensive the making-good needs to be. That said, many damage issues result in finishes needing reinstatement, such as plaster repairs and redecoration.
As broad 2026 guide figures for painting and decorating:
- Repainting a typical room often comes in at around £450
- Decorating a larger home (for example, a 5-bedroom house) may be around £6,000
- Many decorators charge roughly £325 per day, with day rates commonly falling between £250 and £400
These figures generally assume standard trade paint. Higher-end finishes and premium brands will usually increase the overall cost.
Itās also worth noting that āredecorationā can mean very different things. Painting walls only is a different job entirely from redecorating walls and ceilings, refreshing woodwork, repainting doors, or repairing damaged surfaces first. For that reason, estimates are best treated as a starting point rather than a fixed expectation.
Room painting costs by size
Room size has a direct impact on both time and materials, which is why itās often used as the simplest benchmark:
- Small room (approx. 8m²): ~£350
- Medium room (approx. 18m²): ~£450
- Large room (approx. 30m²): ~£1,000
Day rates: how decorators typically price work
Some decorators provide a fixed quote for a room or project, while others charge by the dayāparticularly when thereās uncertainty around preparation and repair time.
A typical UK range is:
- Ā£250āĀ£400 per day, with an average around Ā£325
London and other major cities often sit at the upper end due to higher operating costs.
Examples of common making-good costs
If party wall damage affects internal finishes, repairs often involve a combination of preparation, patching, and repainting. Typical benchmarks include:
Interior painting (average costs)
- Walls: ~£15 per m²
- Ceilings: ~£15 per m²
- Hallways/landings/stairs: ~Ā£1,600
- Doors (both sides): ~Ā£90 each
- Woodwork: ~£15 per m²
- Radiators: ~Ā£15 each
Plaster patching and repairs
In many cases, damage isnāt solved by simply painting over it. Cracking may need opening up, filling, stabilising, and sometimes re-plasteringāeither in a small area or across a broader section to blend the finish properly.
- Minor plaster patching is often Ā£50āĀ£100
Larger plastering works are typically priced separately by a plasterer.
Why two quotes can look wildly different
Even where the visible damage appears similar, the cost to repair it can vary a lot. Common factors include:
- Preparation requirements: filling, sanding, stain sealing, wallpaper removal, caulking, damp treatment
- Access and complexity: high ceilings, stairs, tight spaces, detailed trims
- Scope: one wall versus multiple rooms; isolated patching versus wider blending
- Location: labour and travel costs vary by region
- Finish specification: premium paints, strong colour changes, multiple coats, specialist finishes
Extra items that can push costs up
Repair quotes can rise when additional tasks are needed, such as:
- Removing and disposing of wallpaper
- Extra prep once surfaces are uncovered
- Treating stains or water marks
- Moving furniture and protecting floors
- Dust protection near active works
- Access equipment for external areas (towers/scaffolding)
- Site waste removal
If damage occurs, what happens next?
A properly drafted party wall award usually includes provisions covering what happens if damage occursāoften setting out the requirement to make good (repair) or to provide compensation, depending on whatās appropriate.
The most effective first step is to notify the party wall surveyor as soon as the issue is noticed. They can coordinate inspection, agree the scope of making-good, and keep the process movingāso it doesnāt become an administrative headache for either owner.
