Exterior House Painting in London: When, Why, and How Much It Costs

The exterior of your home is the first thing visitors, neighbours, and potential buyers see. A fresh, well-executed exterior paint job doesn't just improve kerb appeal — it protects your brickwork, render, and timber from the relentless assault of the British weather. But what does exterior house painting cost in London? In this guide, we give you honest, up-to-date pricing for 2026, explain what drives the cost, and share what to look for when choosing an exterior painting contractor in East London.

Exterior House Painting Cost in London: Price Ranges for 2026

For a typical three-bedroom semi-detached house in East London, the cost to paint the exterior ranges from £1,500 to £4,000. The actual figure for your property will depend on size, surface condition, the type of finish required, and access requirements. Here are some typical price brackets:

• Mid-terrace, two-storey (front and rear elevations only): £1,200–£2,200
• Semi-detached, two-storey (three sides): £1,800–£3,200
• Detached, two-storey (four sides): £2,500–£4,500
• Fascias, soffits, and gutters only: £400–£900
• Front door and windows repaint: £300–£600

These figures assume professional preparation and two coats of a quality exterior masonry or timber paint. They do not include scaffolding if required, which is typically charged separately at £300–£800 for a two-storey domestic property.

When Is the Best Time for Exterior Painting in London?

Exterior painting in London is best carried out between April and September, when temperatures are reliably above 10°C and rain is less frequent. Paint manufacturers specify minimum application temperatures, and applying exterior masonry paint in cold or damp conditions leads to poor adhesion, uneven curing, and premature failure.

That said, London's mild autumns mean that October and even early November can be viable for exterior work, particularly on sheltered elevations. We always check forecast weather conditions before beginning exterior projects and won't apply paint to wet or frost-affected surfaces — even if it means a short delay to protect the quality of the finish.

The Importance of Surface Preparation for Exterior Painting

Surface preparation is even more critical for exterior painting than for interior work, because the paint will be exposed to UV light, rain, frost, and temperature fluctuations throughout its life. Cutting corners on preparation is the single biggest reason exterior paint jobs fail prematurely.

A proper exterior preparation process includes:

• Pressure washing or scrubbing all surfaces to remove dirt, algae, and moss
• Allowing surfaces to dry completely before painting begins
• Treating any areas of algae or black mould with a biocidal wash
• Raking out and repointing any cracked or deteriorated mortar joints
• Filling surface cracks in render with an appropriate flexible filler
• Priming all bare or repaired areas before top coats are applied
• Preparing and priming all timber — sanding, back-priming end grain, applying undercoat

At Paez Brothers, we never rush the preparation phase. It's what separates a paint job that lasts 5–7 years from one that starts peeling within 18 months.

Masonry Paint vs Render Systems for East London Homes

East Ham and the surrounding East London postcodes have a wide variety of exterior wall finishes — from exposed London stock brick to smooth sand-and-cement render, pebbledash, and modern through-coloured render systems. Each requires a different product and approach.

Masonry paint is suitable for most painted render and brick surfaces and comes in smooth or textured finishes. Quality brands like Sandtex or Dulux Weathershield offer 15-year guarantees when applied correctly to properly prepared surfaces.

Flexible render coatings are better suited to properties with existing cracking or movement, as they bridge fine cracks and flex with the building rather than cracking themselves. These are more expensive but provide superior protection on older properties.

Timber Windows, Fascias, and Soffits

Many East London properties — particularly Victorian and Edwardian houses — still have original timber sash windows and traditional painted fascias. These require regular maintenance to prevent rot and deterioration. When timber is properly prepared and painted with a quality exterior gloss or microporous paint, it can last 4–6 years between repaints.

Signs that timber needs urgent attention include: flaking or peeling paint, visible bare wood, soft or spongy areas (indicating rot), gaps around frames, and windows that are difficult to open or close. Early intervention is always far cheaper than timber replacement.

How Long Does Exterior House Paint Last?

A quality exterior paint job on a well-prepared surface should last 5 to 7 years before requiring repainting. Factors that affect longevity include the orientation of the property (south-facing walls get more UV exposure), local air quality, and how well the paint was applied. Regular inspection — particularly after harsh winters — allows you to address minor issues before they become major ones.

Does Exterior Painting Require Planning Permission?

In most cases, repainting the exterior of a domestic property in a colour of your choice does not require planning permission. However, if your property is in a Conservation Area (parts of Forest Gate, parts of Walthamstow, and other designated areas across East London) or is a Listed Building, there may be restrictions on colours or materials. We always advise checking with your local council before proceeding if you're unsure.
