Exterior repaint checklist for Kensington stucco and brick before you book

Planning an exterior repaint in Kensington? This checklist explains what to inspect on stucco and brick, how to spot early failure, and what good prep looks like so your finish lasts longer in London weather.

January 22, 2026

Short answer: A long lasting exterior repaint in Kensington starts with inspection and prep, not with colour. Check for hairline cracks, peeling edges, damp signs, rust around metalwork, and failed past filler. Then plan repairs, cleaning, and a breathable paint system that suits stucco or brick. If you want a survey and a clear plan, see our exterior and heritage painting service.

When an exterior repaint fails early, it is rarely because the colour was wrong. It is usually because water got behind the coating, old layers were not stable, or prep was rushed to meet a deadline. In Kensington, exteriors take a lot of weather. Rain, wind, traffic dust, winter freeze and thaw, and strong sun on clear days. Stucco and brick react differently to that stress, and period details add more places for small failures to start.

This checklist is written for homeowners and designers planning work on Kensington period homes. It is not a legal survey and it is not a substitute for a site inspection. It is a practical guide that helps you spot common problems early, ask the right questions, and plan an exterior repaint that looks calm from the pavement and stays that way.

Step 1, identify what you are painting

Kensington homes often mix materials. A front elevation might be stucco with stone details, plus iron railings and timber windows. A side return might be brick. Each needs a suitable approach.

  • Stucco and render often have hairline cracks and older repairs. They usually need a breathable system and careful crack work.
  • Brick can be painted or left natural. If painted, you need to understand the condition of the existing coating and the moisture path.
  • Stone details can stain and spall if moisture is trapped. The wrong coating can make this worse.
  • Metalwork can rust under paint, especially at joints and where water sits.
  • Timber windows and doors need clean edges and a system that can handle movement.

If you are not sure what your facade is made of, take clear photos of the surface texture and details, and get a survey. This step decides the paint system, not just the schedule.

Step 2, look for early signs of failure

Most repaint issues show small warning signs first. Walk the facade slowly and look for these.

  • Peeling edges where old paint lifts at corners, window reveals, and ledges.
  • Blisters small bubbles that can signal trapped moisture or poor bond.
  • Hairline cracks common on stucco, often around corners and mouldings.
  • Wider cracks that may suggest movement or deeper repair needs.
  • Powdering chalky residue on your hand when you rub the wall.
  • Staining under sills, near downpipes, or under cornices where water runs.
  • Green growth algae in shaded areas or on north facing elevations.

These signs do not always mean the whole elevation is failing. They do mean you should not just paint over them. If you do, the new finish can fail in the same spots, often within one season.

Step 3, check water sources first

Water is the main enemy of exterior paint. Before choosing any system, check where water might be getting in or sitting.

  • Gutters and downpipes look for leaks, overflow marks, and staining trails.
  • Parapets and coping stones check for open joints and cracks.
  • Window sills look for water sitting on flat sections and failed seal lines.
  • Basement areas check for damp patches, salt staining, and bubbling paint.
  • Balconies and railings check joints where water can sit and rust can begin.

If a gutter is leaking, repainting the wall below it will not last. Fix the water source first, then repair and repaint. This is one reason exterior and heritage work should begin with a survey, not a colour chat.

Step 4, decide what “prep” really means on a period facade

Prep is not one step. It is a set of steps that make the surface stable, clean, and ready to accept a new system. Period facades often need more than modern ones because of old repairs and many layers of paint.

Typical prep stages can include:

  • Cleaning to remove traffic film, algae, and loose matter.
  • Scraping back loose paint to sound edges.
  • Sanding and feathering edges so the surface reads as one.
  • Repairing cracks and failed filler with suitable materials.
  • Priming bare areas and repaired areas correctly.
  • Spot treating rust on metalwork and priming before top coats.

A proper repaint should not look thick and lumpy. It should look calm. That calm look comes from flattening and blending, not from adding more layers on top of old ones.

Stucco in Kensington, crack repair and breathability

Stucco can look beautiful when it is cared for, yet it is prone to fine cracking. Some cracks are cosmetic. Some allow water to enter. The right approach depends on the crack type and the location.

Practical guidance:

  • Hairline cracks often need careful opening, filling, and blending, not just paint over the top.
  • Cracks at corners can signal movement. These need assessment before filling.
  • Repeated cracking in the same place can mean the base repair failed. It may need reworking.

Breathability matters for many period walls. When a wall needs to release moisture, a dense film can trap it and create blisters. A suitable heritage approach aims to protect the surface while letting the building behave naturally. This is part of what we cover on our exterior and heritage painting page.

Brick, painted or not, and what to watch for

Some Kensington properties have brick facades or side returns that have been painted in the past. Painted brick can look smart, yet it needs careful handling because brick is porous and holds moisture.

Checks for painted brick:

  • Look for flaking and powdering, which can signal old coating failure.
  • Check for salt staining and bubbling, often linked to moisture movement.
  • Assess if the existing coating is breathable or not.
  • Check mortar joints, since water often enters through failed pointing.

If brick is unpainted and you are considering painting it, it is worth discussing the long term impact. Paint can change how the wall handles moisture. A survey helps you decide if painting is a good idea for that elevation, or if a different finish makes more sense.

Metalwork, railings, gates, and rust traps

Iron railings and gates are a major part of the Kensington look. They also fail in predictable places, especially where water sits.

Common rust traps:

  • Bottom rails close to the ground where splash back happens.
  • Joints and welds where water can sit under paint.
  • Where railings meet masonry, especially if seal lines failed.
  • Horizontal surfaces such as top rails and flat caps.

A clean finish on metalwork comes from rust removal, correct primers, and careful top coats. Painting over rust does not stop it. It hides it for a short time, then it breaks through again.

Windows and joinery, the details people notice most

Timber windows and doors often show wear first because they move, they get sun and rain, and they are touched constantly. A good repaint here is about sharp lines and stable bond.

Checklist for joinery:

  • Look for peeling at glazing bars and lower rails.
  • Check for soft timber, which can mean rot or long term water exposure.
  • Check putty lines and seal joints for gaps.
  • Look for sticking sashes, which can be linked to paint build up.

Joinery is where “quick work” looks obvious. Clean prep and careful finish coats can make the whole elevation feel more expensive, even if the main wall colour stays classic.

Choosing sheen for the exterior

For many period exteriors, a softer sheen often looks more natural on stucco and render. High gloss can feel too sharp and can show defects more clearly. Metalwork and joinery may use a different sheen for durability and definition, but the main wall finish often benefits from staying calmer.

The best choice depends on the facade detail, the light, and how perfect the substrate is. On a very flat modern surface, higher sheen can look clean. On textured heritage stucco, a softer look often reads better.

Colour comes after prep, but it still needs a method

Once the surface plan is clear, colour selection becomes easier. In Kensington, classic families tend to work well because they respect the street and cope with weathering.

  • Warm off whites and soft stone tones for stucco.
  • Deep charcoal or near black for railings.
  • Deep greens or deep blues for front doors if you want character.

The safest way to choose is to test on the wall, even outside. Light and shadow can change the colour a lot. Test patches help avoid a repaint regret.

Timing, weather, and why scheduling matters

Exterior work needs sensible timing. Rain can interrupt prep and coating stages. Strong direct sun can affect how paint dries. Wind can carry dust onto wet surfaces. A good schedule builds in flexibility and keeps the work methodical.

If you have a fixed date, for example guests, an event, or a move, it helps to plan early. The best results come when the team can do prep, repairs, priming, and coats without rushing. Rushing is when edges stay rough and failures return quickly.

What to ask your decorator before you book

If you are speaking to contractors, these questions help you understand the plan and the quality level.

  • How will you handle loose and unstable old paint, scrape only, or full feathering to a clean edge?
  • How will you repair cracks and old failed filler, and what materials will you use?
  • How will you handle moisture issues, and will you check gutters and downpipes?
  • What is the paint system for stucco or render, and why is it suitable for a period property?
  • How will you treat rust on railings before top coats?
  • How will you protect details and keep edges crisp around windows and mouldings?

Good answers are usually specific. Vague answers often signal vague prep.
