External rendering is applying a protective, weather-resistant coating to the outside walls of a house, using sand and cement, monocouche or thin-coat silicone render, to give a smooth or textured finish that protects the masonry and improves appearance.

| Typical semi-detached | All rendered walls of a 3-bed semi in monocouche or silicone, with scaffolding. | £9,100–£21,000 |
| Detached or full strip and re-render | Larger houses, or homes needing old render removed and walls repaired first. | £19,500–£39,000 |
Your price depends mostly on:
- Render system: sand and cement, monocouche or silicone
- Removing old render or pebbledash and repairing the walls
- Scaffolding, access and protection of neighbouring property
- Detailing around windows, bays, sills and pipes
What’s included?
- Scaffolding erected and removed, with neighbours' access agreed
- Removal of loose or failed render and pebbledash where needed
- Beads at corners, edges and above the damp-proof course
- Mesh reinforcement and base coats to suit the chosen system
- Finish coat in your chosen colour and texture
- Making good around pipes, vents and fixings, and a site clean-up
Local housing and external rendering
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
That mix of housing shapes how we approach external rendering in Morden: the age and construction of your home affect the materials, the method and, in the end, the price.
Do you need permission in Morden?
The notes below cover England, which is where Morden sits. Rules change and every property is different, so we speak to the council before pricing your job.
In England, re-rendering or cladding a house is often allowed without planning permission, but stone, render, timber, plastic or tile cladding is not permitted development in conservation areas, and listed buildings need consent.
If you render or re-clad more than 25% of an external wall, Building Regulations usually require the wall’s insulation to be improved where that is practical, and building control should be notified.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Survey and measure
A free survey comes first. It gives us what we need to price external rendering properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
After the survey we send a quote for external rendering that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Plan and prepare
Preparation matters as much as the build. We agree access, parking and working hours with you, order materials in good time, and confirm any permissions so the job isn't held up once it starts.
The work itself
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.

External rendering in Morden: questions
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from external rendering, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
What time of year should rendering be done?
Render needs mild, dry conditions to cure properly, so spring to early autumn is ideal. Most render systems should not be applied when frost is likely, in heavy rain or in strong direct sun, which can dry it too quickly and cause cracking. We plan the programme around the forecast and may pause work if the weather turns, which protects the finish.
How do I look after silicone or monocouche render?
Through-coloured render needs little upkeep. Check it once a year for cracks or damage, especially around windows and pipes, and keep gutters clear so water does not run down the walls. If green algae appears on shaded walls, a specialist render cleaner applied with a soft brush or low-pressure wash removes it. Avoid high-pressure jet washing, which can damage the surface.
Can you combine external rendering with other work?
Yes. Because we manage several trades under one contract, we can plan external rendering alongside other work on your Morden home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
Do I need planning permission to render my house?
Whether rendering needs planning permission depends on how it changes the appearance, your home's location, whether it is listed or in a conservation area, and which UK nation you are in. Rendering over brick may need permission in some places, while replacing existing render like for like often does not. Listed buildings need consent. We check the position before quoting.
