Render and facade repair in Greenwich

External rendering and facade repair in Greenwich, 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.

Greenwich overview

External rendering and facade repair in Greenwich

A large stock of Victorian and Edwardian houses with essentially no dedicated roofing competitor coverage. Greenwich falls well within the South East London ground Lian Construction covers on a regular basis. For external rendering and facade repair work in Greenwich, that local knowledge means fewer surprises once work is on site and a team that already understands the borough's typical property stock.

Greenwich has a large stock of Victorian and Edwardian houses, much of it terraced or semi-detached, built in the decades either side of 1900 as London's suburbs expanded along the riverside and rail lines. As with similar housing across inner and near-inner London boroughs, roofs on these properties are typically slate or clay tile, often with parapet walls, valley gutters, and multiple original chimney stacks. Many houses will have had partial re-roofing, loft conversions, or rear extensions at some point over the past century, which means roof coverings and detailing are frequently mixed ages even on a single property. Bay windows with their own small roofs, and shared or party-wall guttering between terraced neighbours, are common features that need particular care during repair work. Given the age of this housing stock, issues such as slipped or missing tiles, ageing lead flashing around chimneys, and worn valley gutters are the kind of thing homeowners in Greenwich are likely to encounter periodically, rather than one-off problems. Property condition varies a good deal street by street depending on maintenance history, so what one house needs can differ significantly from its neighbour.

With a large stock of Victorian and Edwardian houses and essentially no dedicated roofing competitor coverage in the area, homeowners and landlords in Greenwich are often left choosing between general builders who treat roofing as a sideline, or firms based further afield who may not prioritise smaller local jobs. This gap tends to show up most clearly with urgent repairs, where a slipped tile or a leak after a storm needs someone who can attend quickly rather than fit the job in around larger contracts elsewhere. It also affects planning and quoting for larger work such as full re-roofs or chimney repairs, where a lack of specialist local knowledge can mean longer lead times or less accurate initial assessments. For landlords managing older rental stock, this matters because roof issues left unresolved tend to escalate into damp and interior damage, which is more disruptive and costly to fix than catching problems early. Homeowners undertaking wider refurbishment work, such as loft conversions or extensions, may also find it harder to coordinate roofing specifically as part of a bigger project if there isn't a contractor locally who covers that trade in depth. In practice, this means demand for reliable, responsive roofing and refurbishment work in Greenwich likely outstrips the readily available supply.

Given the concentration of Victorian and Edwardian houses in Greenwich, conservation area and, in some cases, listed building considerations are worth checking before starting roofing or exterior refurbishment work. As in many outer and inner London boroughs with older housing stock, parts of Greenwich may fall within conservation areas, where changes visible from the street, such as replacing roof coverings with a different material, altering rooflines, or adding roof windows to a front elevation, can require planning permission even where similar work elsewhere would be permitted development. Chimney stacks and original architectural detailing are often specifically protected in these areas. It's worth checking with the local planning department or a surveyor early on, since retrospective permission is harder to secure than getting it sorted before work starts. This doesn't apply to every property, and plenty of routine repairs and like-for-like replacements fall outside these controls, but it's a sensible thing to verify given the age of the housing stock.

Render and External Wall Insulation (EWI)

External Wall Insulation systems, increasingly common on solid-wall Victorian and ex-council properties looking to improve thermal performance, change how the render on a wall needs to be specified and detailed. EWI involves fixing rigid insulation boards to the outside of the wall, then applying a reinforced base coat with mesh embedded into it, followed by a top coat, usually a silicone or acrylic render, rather than rendering directly onto brick. Where we're asked to re-render a wall that already has EWI installed, or to repair render that's failed on an EWI system, the detailing at openings matters more than on a solid masonry wall, since window and door reveals, meter boxes and pipe penetrations all need the insulation and render built up correctly around them to avoid a thermal bridge or a point where water can track behind the system. Reveal depth changes too, since adding insulation and render to an external wall typically adds 80 to 150mm of thickness depending on the insulation used, which affects how windows, door thresholds, cills and rainwater goods need to be extended or re-detailed to sit properly against the new wall face. We don't design or specify EWI insulation systems as a standalone service, but where render work is needed on a wall with EWI already fitted, or as part of a wider EWI installation being coordinated by others, we work to the system manufacturer's detailing requirements so the render performs and weathers as the system was designed to.

Conservation areas and planning considerations for render

Render is often the single biggest visual element of a street-facing elevation, which is exactly why conservation areas and Article 4 directions frequently place restrictions on changing it. In many conservation areas, painting over previously unpainted render, or changing the render colour on the principal elevation, from a natural sand and cement finish to a bright modern colour for example, can require planning permission even though the same change would be permitted development on an unlisted property outside a conservation area. Some councils also restrict changing render texture or replacing traditional lime or sand and cement render with a modern silicone or monocouche system on street-facing elevations, since the visual character of a terrace often depends on a consistent render finish across neighbouring properties. Listed buildings carry stricter controls again, and render specification on a listed property, including colour, texture and material, is very likely to need listed building consent regardless of how minor the change looks in practice. On a terrace of uniformly rendered Victorian or Edwardian houses, render finish and colour often forms part of what gives the street its character as a whole, which is one of the main reasons conservation area controls focus on it specifically rather than on less visible changes. Where several neighbouring properties have already changed their render finish or colour without consent, that doesn't necessarily set a precedent that makes a similar change acceptable for your property, since councils can and do take enforcement action retrospectively, so it's worth checking the current position for your specific address rather than assuming what's already been done nearby is a reliable guide. We flag at survey stage where a property's location is likely to bring render work into scope for planning or listed building consent, but confirming the position and making any application is a separate process handled by the property owner, or an architect or planning consultant working on their behalf, rather than something we apply for on the client's part.

Signs to look for

Do you need external rendering and facade repair in Greenwich?

  • 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.
  • Sections of render sound hollow when tapped, or have visibly bulged or blown away from the wall in one or more patches.
  • Damp patches appear on internal walls behind a rendered elevation, especially after wet weather, suggesting moisture trapped behind the render.

Questions

External rendering and facade repair questions in Greenwich

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

Greenwich is part of our regular South East 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 Greenwich?

Yes. Greenwich falls within the area Lian Construction serves across Greater London.

Do you apply K Rend or other silicone render systems?

Yes. K Rend and comparable silicone render systems are applied over a mesh-reinforced base coat, with colour built into the render rather than relying on paint, which suits homeowners who want a low-maintenance, crack-resistant finish that doesn't need repainting every decade. They're a good fit for cavity-wall properties and extensions, and can also work well over External Wall Insulation systems. On solid-wall period properties we'd talk through whether a silicone system or a more breathable lime specification suits the wall better before recommending one over the other.

Will render work need scaffolding?

For anything above ground floor level, yes, in almost all cases. Render needs to be applied and finished consistently across a wall in one continuous process, which isn't practical from a ladder, and scaffolding also protects neighbouring property, pedestrians and parked cars from debris and overspray during preparation and application. We factor scaffolding into the quote as a separate line, since it's often needed for a longer period than the render application itself, to allow proper curing time before it comes down, and its cost varies with the height and length of the elevation being worked on.

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.
