Render and facade repair in Kensington and Chelsea

External rendering and facade repair in Kensington and Chelsea, London

Lian Construction carries out external rendering and facade repair across London, working from our Kingston upon Thames base out across South West London and the wider capital. We apply and repair sand and cement render, K Rend and other silicone renders, and monocouche systems, and we re-render properties where existing render has failed or trapped damp behind it. Work includes full elevation re-rendering, patch and crack repair, pointing and detailing around window and door reveals, and facade cleaning and repainting. Many of our render projects are on Victorian and Edwardian solid-wall terraces, where the right render specification depends on the wall build-up as much as the finish you want.

Kensington and Chelsea overview

External rendering and facade repair in Kensington and Chelsea

Premium Central London borough where finishing quality — tiling, plastering, decorating — is the deciding factor on every project. Kensington and Chelsea falls well within the Central London ground Lian Construction covers on a regular basis. For external rendering and facade repair work in Kensington and Chelsea, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.

Kensington and Chelsea is dominated by period property. Stucco-fronted Victorian and Georgian terraces, garden squares, mansion blocks and mews houses make up a large share of the borough's housing stock, much of it dating from the 1800s. Ceiling heights, cornicing, sash windows and original plasterwork are common in these properties, which is part of why finishing quality carries so much weight on a project here — the existing detailing sets a high bar, and any new tiling, plastering or decorating has to sit alongside it convincingly. A large proportion of the borough falls within conservation areas, and there is a higher-than-average concentration of listed buildings compared with most of London. Basement conversions, loft extensions and internal reconfigurations of older terraces are common project types, often on properties that have already been altered several times over the decades. Newer flats and mansion blocks exist too, particularly nearer the borough's busier corridors, but even these tend to have higher specification finishes than the London average, so the same emphasis on tiling, plastering and decorating quality applies across most of the housing stock, not just the period buildings.

In a premium Central London borough like this, the finish is what homeowners and landlords notice first and remember longest. Structural work matters, but a project can be sound behind the walls and still feel like a failure if the tiling is uneven, the plaster shows joints under light, or the decorating looks rushed. That raises the bar for any contractor working here — clients in Kensington and Chelsea tend to have seen good finishing before, in their own homes or others', and they know what it looks like when it is done properly. For landlords, this matters commercially as well as aesthetically: a flat presented with a poor finish is harder to let at the rents the area commands, and tenants at this price point notice the same details owner-occupiers do. For homeowners, redoing a badly finished tiling or plastering job is disruptive and expensive, which makes getting it right the first time worth more here than in most areas. Given the concentration of high-value property, competition among contractors able to deliver consistently high-quality finishing work is real, and it tends to be finishing standard, not price alone, that decides who gets the work.

Given how much of Kensington and Chelsea's housing stock is period property, conservation area status and listed building consent are recurring considerations for refurbishment work in the borough. Many alterations that would be straightforward elsewhere — replacing windows, altering facades, or changing rooflines — can require planning permission or listed building consent here, and conservation area rules often extend to details like window materials, render finishes and external decoration colours. This does not affect every job; plenty of internal refurbishment, redecorating and like-for-like repair work falls outside these controls. But for anything touching the exterior, the roofline or a listed structure, it is worth checking the property's planning status early, ideally before finalising a scope of work, since consent requirements can affect both timeline and the materials that can be used.

What drives the cost of rendering work

Render pricing depends on access and area more than most people expect. Scaffolding is usually needed for anything beyond ground floor level, and a full terrace elevation on a three-storey Victorian house costs considerably more to scaffold than a single-storey rear extension, so access sometimes ends up being a larger line item than the render itself on a modest repair. Substrate condition is the next major factor: removing failed cement render down to brick, especially where it's been on the wall for decades and is well bonded in places, takes far longer than applying render to a clean, sound background, and a wall with historic patch repairs in mismatched materials sometimes needs more preparation than a wall that's never been touched. Render system choice affects both material and labour cost, monocouche and silicone renders are typically applied in fewer coats than traditional sand and cement with a separate top coat, which affects labour time, though material cost per bag or per square metre varies the other way. Detailing adds cost too: window and door reveals, string courses, decorative mouldings and downpipe brackets all need cutting in around carefully rather than rendering in one flat pass, and a plain elevation renders faster than one with a lot of period detailing to work around. As a general guide, a single-storey rear extension elevation might be scaffolded, prepared and rendered within a week to ten days, while a full three-storey terrace elevation with substantial preparation typically runs two to three weeks once curing time between coats is factored in. Labour tends to be the larger share of the cost on a heavily prepared wall, since stripping decades-old cement render safely without damaging the brick behind it is slow, careful work, whereas material cost dominates more on a straightforward re-render over a sound, already-prepared substrate. We price rendering work after a proper survey of the elevation and substrate, broken down by scaffold, preparation, render system and detailing, rather than a blanket rate per square metre that doesn't reflect what a specific wall actually needs.

Render systems compared: sand and cement, K Rend, monocouche and lime

Traditional sand and cement render is applied in two or three coats, a scratch coat, a floating coat and sometimes a setting coat, and finished with a texture such as a wood float, scraped or roughcast finish, then usually painted. It's a well-understood, relatively affordable system, but it's rigid and prone to cracking if the mix ratio is wrong for the background or if it's applied too thickly in one pass. K Rend and other silicone renders are polymer-modified, factory-mixed systems applied over a base coat and mesh, and they're more flexible and crack-resistant than sand and cement, with colour built into the render itself rather than relying on paint, which means the colour doesn't need repainting every decade in the way a painted cement render does. Monocouche render is a single-coat, through-coloured system applied in one pass over a mesh-reinforced base, and it's popular on newer builds and extensions for speed of application, though it needs the right weather conditions and a skilled hand to avoid an uneven, patchy finish. Lime render is the traditional specification for solid-wall period properties and behaves quite differently to the modern systems: it's breathable, allowing moisture to pass through and evaporate rather than trapping it, and it flexes slightly with the building's natural movement rather than cracking. We specify the system to suit the wall it's going onto rather than defaulting to one product across every job, since the wrong render on the wrong substrate is one of the most common causes of render failure we're called out to fix.

Signs to look for

Do you need external rendering and facade repair in Kensington and Chelsea?

  • Render around window and door reveals has cracked or come away, letting water track in around the frames during heavy rain.
  • The render looks tired, stained or algae-covered but is otherwise sound, and a clean and repaint would refresh it without full replacement.
  • You're planning a wider refurbishment or facade upgrade and want render assessed alongside brickwork, windows and other exterior works together.
  • Render on the front or side elevation shows visible cracking, particularly stepped or spreading cracks rather than a single fine hairline.

Questions

External rendering and facade repair questions in Kensington and Chelsea

How quickly can Lian start external rendering and facade repair work in Kensington and Chelsea?

Kensington and Chelsea is part of our regular Central London coverage, so once we've surveyed the property we can usually confirm a start date quickly. Send the address and scope and we'll arrange the next step.

Do you cover all of Kensington and Chelsea?

Yes. Kensington and Chelsea falls within the area Lian Construction serves across Greater London.

Do I need planning permission to re-render my house?

It depends on the property. Outside a conservation area and where the property isn't listed, re-rendering with a similar finish is often permitted development. Inside a conservation area, changing render colour, texture or painting a previously unpainted elevation can require planning permission, and listed buildings almost always need listed building consent for render changes regardless of how minor they look. We'll flag at survey stage if your property's location is likely to bring the work into scope for consent, though confirming the exact position and making any application is handled by you or a planning consultant, not by us directly.

How long does a full re-render take?

It depends on the size of the elevation, the render system and the weather. A single-storey rear extension might take a few days to a week once scaffold is up. A full three-storey terrace elevation, including stripping old render, repairing the substrate and applying a new system in the correct number of coats with proper curing time between them, more commonly runs two to three weeks. Render needs a settled weather window to go on and cure properly, since rain, frost or strong sun during application or early curing can all cause defects, so we build a weather allowance into the programme rather than a best-case figure.

Can render be cleaned and repainted instead of replaced?

Yes, where the existing render is structurally sound and the problem is mainly appearance, algae staining, general dirt or a dated colour. We clean the surface properly, treat any biological growth, and repaint with a suitable masonry paint, breathable where the render itself is breathable, rather than sealing a permeable render with the wrong type of paint. This is a considerably cheaper option than full re-rendering, though it only makes sense where the render is genuinely sound underneath, so we'll check for cracking and hollow areas before recommending a clean and repaint over a repair.

Does render work interact with brickwork repointing or repair?

Yes, quite often. Where render has failed and needs stripping back to brick, the exposed brickwork sometimes needs repair or repointing before new render goes on, particularly where the wall has been damp for a while or where old pointing has failed underneath the render. We can coordinate rendering and brickwork repair as one project so the wall gets a proper structural and weatherproofing fix before the finish goes back on, rather than rendering over brickwork that needed attention first and storing up a problem behind the new coat. This tends to work out cheaper overall than instructing two separate contractors, since scaffold and access only need arranging once for both trades.
