Masonry Painting Services in Hampstead
Rendered Walls
Rendered facades are the most common exterior masonry surface. Render types include smooth sand and cement render, pebbledash, and roughcast.
Smooth render in good condition needs cleaning, biological growth treatment, and a masonry primer before two topcoats. Pebbledash with friable or loose sections needs stabilising treatment to consolidate the surface. Applying masonry paint over unstabilised friable render causes the finish to pull away as it dries.
For combined projects, see our exterior painting page. Rendered facades are often painted at the same time as wood painting of soffits, fascias, and frames.
Exposed Brick
Painted brick facades are common across NW London. Once painted, brick typically needs repainting regularly.
We assess the existing paint condition, clean the surface, and apply flexible masonry paint in the same or updated colour. London stock brick that has never been painted can be treated with a clear waterproof masonry sealant for protection without colour change.
Stone Facades
Ragstone, flint, and dressed stone features are found on older properties in Hampstead village. Stone surfaces are treated with breathable masonry paint only.
Standard impermeable masonry paint causes moisture to become trapped and leads to spalling. We assess stone surfaces carefully before recommending treatment. Some benefit from cleaning alone.
Breathable Coatings
Breathable masonry paint is correct for all properties with lime mortar or lime render, including Grade II listed properties. Standard acrylic masonry paints trap moisture and cause damp to develop internally.
We stock breathable masonry paint systems as standard. On listed or lime mortar properties, we use breathable products without being asked. This is not optional.
Biological Growth Treatment
Algae, lichen, and moss growth is common on north-facing or shaded masonry. Painting over active biological growth results in a finish that fails quickly.
We apply specialist biological growth treatment and allow it to work before cleaning and painting. Mechanical scrubbing alone does not kill the spores.
How Masonry Painting Works
1. Surface Inspection
We inspect for hollow sections, friable areas, biological growth, cracks, and existing paint condition.
2. Stabilising Treatment
Friable or powdery render is treated with a masonry stabiliser. This consolidates the surface before any paint is applied.
3. Biological Growth Treatment
Growth is treated with specialist biocide and left to die off. The surface is cleaned and dried before painting begins.
4. Masonry Primer
A full masonry primer coat is applied across the surface. This seals and improves paint adhesion.
5. First and Second Coat
Two full coats of flexible or breathable masonry paint are applied, giving a durable, weatherproof finish.

Masonry Painting Costs in London
Prices below are estimates only. Every facade is different. Call 020 4634 9779 for a precise quote.
Surface Area and Height
A 2-storey facade is very different from a 5-storey townhouse. Height requires scaffolding, adding cost above two floors.
Front facade of a Victorian or Edwardian terrace in West Hampstead or Primrose Hill (2 storeys): £1,200 to £2,500.
Surface Condition
Friable or soft render needing stabilising treatment adds preparation time and cost. A semi-detached Edwardian rendered facade (Compayne Gardens, West Hampstead) typically costs £1,800 to £3,200.
Coating Type
Standard masonry paint suits modern cement render. Breathable systems are needed for listed properties and lime mortar buildings.
Full exterior masonry on a Georgian townhouse in Hampstead village using a breathable system typically costs £5,000 to £10,000.
Listed Buildings and Lime Mortar
Georgian townhouses in Hampstead village with lime mortar must use breathable masonry paint. Standard impermeable paint traps moisture and causes damp to develop internally.
This is the correct technical requirement, not aesthetic preference. We advise on listed building consent where needed before any external paintwork begins.
