Staircase Painting in a London Townhouse: Heights, Access & Finishes

The staircase is the spine of a London townhouse. It connects every floor, it is the first interior space visitors experience, and in a Georgian or Victorian property, it is often an architectural set piece in its own right, with sweeping banisters, turned balusters, carved newel posts, and decorative plasterwork that extends from the entrance hall to the top of the house.

Painting a townhouse staircase is also one of the most challenging projects a decorator can undertake. The combination of extreme heights, restricted access, continuous use by residents, intricate woodwork, and the need for a durable finish that withstands constant foot traffic makes it a specialist job that demands experience, proper equipment, and meticulous planning.

This guide covers the practical realities of staircase painting in London townhouses, from the access solutions needed to reach four-storey stairwells to the finishes that will stand up to daily use.

The Access Challenge

Understanding Stairwell Heights

A typical London townhouse stairwell extends from the lower ground floor to the second or third floor, creating a vertical void that can be twelve to fifteen metres high. Even a modest three-storey terrace in Pimlico will have stairwell walls that extend eight to ten metres from ground to ceiling.

Painting these walls and the associated cornicing requires working at heights that are dangerous without proper equipment and training. Ladders alone are not suitable for stairwell work; the angles, the gaps between treads, and the need for stable working positions at multiple heights demand more sophisticated solutions.

Scaffold Towers and Stairwell Platforms

The safest and most efficient access solution for stairwell painting is a purpose-built stairwell scaffold. These systems are designed to bridge the stairwell void, providing a stable working platform at the required height while still allowing passage up and down the stairs below.

Professional stairwell scaffolds have several key features:

• Adjustable legs that accommodate the height difference between stair treads
• Guardrails on all open sides to prevent falls
• Locking castors where applicable for repositioning
• Modular construction that allows the tower to be built incrementally within the confined space of a stairwell

For taller stairwells in properties across Belgravia and Kensington, where the void may extend four or five storeys, a more complex scaffold arrangement may be needed. In some cases, the scaffold must be built in stages, with lower sections being painted and the scaffold then raised to reach higher areas.

Protecting the Staircase

Before any scaffold is erected, the staircase itself must be thoroughly protected:

• Treads and risers: Covered with dust sheets and then hardboard or heavy-duty protective film to prevent damage from scaffold feet and foot traffic.
• Handrails and balusters: Wrapped in protective material if they are not being painted. If they are being painted, they are typically done after the walls and ceiling to avoid damage from scaffold erection and removal.
• Stair runners and carpets: Should be lifted before work begins. This is the ideal time to have the carpet professionally cleaned before refitting, or to replace it entirely.

Maintaining Access

In a family home, completely blocking the staircase for days or weeks is impractical. A professional painting team plans the work to maintain access at all times, even if this means erecting and partially dismantling the scaffold daily, or working on one half of the stairwell at a time.

Preparation

Walls and Ceilings

Stairwell walls and ceilings accumulate dirt, dust, and scuff marks over the years. Before painting:

• Wash down: All surfaces should be washed with sugar soap to remove grease and dirt. In a stairwell, this is particularly important on the lower sections of walls where hands brush the surface daily.
• Fill and sand: Fill any cracks, holes, and dents. Stairwell walls are prone to cracking at corners and around door frames due to the vibration of doors closing throughout the house.
• Sand back: Sand all surfaces to provide a key for the new paint. Remove any flaking or peeling paint.
• Prime: Spot-prime any bare plaster, filled areas, or stained patches with an appropriate primer.

Woodwork

The woodwork in a townhouse staircase, the handrail, balusters, newel posts, string, skirting, and any panelling, requires particularly thorough preparation:

• Clean and degrease: Handrails accumulate oil from hands over years. Clean thoroughly with sugar soap, and consider a light wipe with white spirit on stubborn areas.
• Sand: Sand all surfaces to remove the gloss from the existing finish and provide a key. Pay attention to the turned profiles of balusters, which have recesses that need careful sanding.
• Fill: Fill any cracks at joints between balusters and handrail, between string and treads, and at any point where movement has opened gaps.
• Strip if necessary: If the existing paint on woodwork is thick, uneven, or badly failing, stripping back to bare wood may be necessary. This is time-consuming but produces the best results on heritage woodwork.

Painting the Walls and Ceiling

Product Choice

Stairwell walls need paint that combines good appearance with practical durability. The lower sections of the walls, up to about waist height, take more wear than the upper sections, and a more durable finish here is justified.

• Upper walls and ceiling: A good quality matt emulsion such as Little Greene Intelligent Matt or Dulux Trade Diamond Matt. In very tall stairwells, a flat matt ceiling paint on the ceiling proper, with the wall colour carried up to the cornice.
• Lower walls: Consider a slightly more durable finish on the lower half, such as Dulux Trade Diamond Matt or a silk emulsion. In period properties with a dado rail, the natural division between the rail and the skirting is the perfect area for a harder-wearing finish.
• Cornicing: Stairwell cornicing should be painted with a brush to work paint into the moulding detail. If the cornice runs the full height of the stairwell, it provides a continuous decorative element that unifies the space. See our guide to painting cornices and ceiling roses for detailed techniques.

Colour Choices

Staircase colour schemes should consider both aesthetics and practicality:

• Light colours make stairwells feel more spacious and reflect available light downwards through the house. In a narrow townhouse stairwell, this is a significant practical benefit.
• The same colour throughout creates a sense of continuity and makes the staircase feel like a single, unified space from bottom to top.
• A gradual lightening of colour from ground floor to top floor can create a sense of ascending into light, which is particularly effective in taller townhouses.
• Dado treatment: Using a stronger colour below the dado rail and a lighter colour above is both practical (marks show less on the lower section) and aesthetically effective, adding horizontal interest to the vertical space.

Popular stairwell colours in London townhouses include Farrow & Ball Strong White, Ammonite, and Skimming Stone; Little Greene Slaked Lime, French Grey Pale, and Loft White; and Dulux Heritage DH Linen and Raw Cashmere.

Painting the Balustrade

The Full Balustrade System

A townhouse balustrade typically comprises:

• Newel posts: The substantial vertical posts at the top and bottom of each flight, and at any turns or landings.
• Handrail: The continuous rail running between the newel posts.
• Balusters (spindles): The individual vertical elements between the handrail and the string.
• String: The inclined board running along the side of the staircase, into which the balusters are fixed.

Painting a balustrade properly is one of the most labour-intensive tasks in domestic decoration. A typical London townhouse staircase running from lower ground to second floor may have two hundred or more individual balusters, each of which must be painted individually on all four sides, plus the turned profile.

Technique

• Balusters: Each baluster should be painted individually with a small brush, typically a one-inch or one-and-a-half-inch brush. Work the paint into the turned profile, covering all recesses and edges. Two coats of satinwood or eggshell are standard.
• Handrail: The handrail must be painted smoothly, as any brush marks or runs will be felt by every hand that uses it. Apply thin, even coats and tip off with a light brush stroke along the length of the rail. The top surface of the handrail should be slightly glossier than the underside for durability.
• Newel posts: These often have carved or moulded detail that requires careful brush work. The tops of newel posts may have caps or finials that should be painted or polished separately.
• String: The exposed face of the string is usually painted with the same product and colour as the rest of the woodwork. Where the string meets the wall, ensure a clean line.

Finish Choice

The choice between eggshell and satin for balustrade woodwork depends on the look you want:

• Eggshell: A subtle, low-sheen finish that suits period properties and creates a sophisticated, contemporary look. Less durable than satin and shows wear more quickly on high-contact areas like handrails.
• Satin: A mid-sheen finish that is more practical for handrails and high-contact areas. It resists marks better and is easier to clean.
• Gloss: Traditional but increasingly uncommon. Provides the most durable finish but can look overly shiny in a modern context. Still appropriate for some Victorian properties where a high-gloss finish is period-authentic.

Stair Treads and Risers

If the staircase has exposed treads and risers rather than carpet, painting them requires specific products and techniques:

• Treads: Must be painted with a floor paint or a tough, anti-slip finish. Standard woodwork paint will wear through quickly under foot traffic. Dulux Trade Floor Paint or Little Greene Floor Paint are suitable options. Consider adding an anti-slip additive to the paint on treads.
• Risers: Can be painted with standard woodwork paint as they receive no foot traffic. A contrasting colour between treads and risers can create a striking visual effect.
• Runner gaps: If a carpet runner is fitted, the exposed edges of the treads and the painted borders require careful masking and painting. Ensure the paint system is applied before the runner is refitted.

Timing and Disruption

Project Duration

A complete staircase repaint in a three-storey London townhouse, including walls, ceiling, cornicing, and the full balustrade, typically takes one to two weeks for a team of two painters. A four or five-storey property in Belgravia or Knightsbridge may take two to three weeks.

Minimising Disruption

We understand that the staircase is in constant use and that blocking access is not feasible for extended periods. Our approach includes:

• Working systematically from top to bottom so completed sections remain accessible
• Erecting and adjusting scaffold to maintain passage at all times
• Protecting all surfaces to allow safe movement through the work area
• Scheduling the most disruptive work, such as scaffold erection, for times that suit the household
