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.
If you have external rendering on your list for a property in Hook, we can help from the first measurements to the final clean-up. For a typical home, plan for 1–3 weeks on site, depending on weather, though larger or more complex jobs take longer. We cover postcodes KT5, KT6, KT7 and KT9 and nearby Chessington, Surbiton and Esher, and every quote we send is fixed for the scope described in it.

How much does external rendering cost in Hook?
No two jobs cost exactly the same, but the ranges below give a fair picture of external rendering in Hook. Pricing for London runs about 30% above the national guide, and the overall guide is £9,100–£21,000 with VAT included. We'll confirm your figure after surveying the property for free.
| Type of job | What it usually involves | Guide in Hook |
|---|---|---|
| Front elevation or small terrace | One elevation or a small terraced house, including scaffolding and preparation. | £3,900–£9,100 |
| 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 |
The main things that change the figure:
- Wall area to be rendered and the height of the house
- Render system: sand and cement, monocouche or silicone
- Removing old render or pebbledash and repairing the walls
- Detailing around windows, bays, sills and pipes
Scope of the work
- Survey of walls, existing render, cracks and damp-proof course
- Scaffolding erected and removed, with neighbours' access agreed
- Windows, doors and surfaces masked and protected
- 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
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 variety is why a guide price for external rendering in Hook is only a starting point; the survey shows what your particular property needs.
Do you need permission in Hook?
Hook is in England, so the planning and building rules set out below are the ones that apply. We confirm the details with the council before we quote.
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
We look at the job
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for external rendering so the price reflects your home.
Price and scope agreed
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for external rendering.
Dates and permissions
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Hook property.
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.
Why homeowners choose us
External rendering in Hook: questions
Do I need planning permission in Hook?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Hook is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
Can you render over pebbledash or old render?
Rendering over existing pebbledash or render is sometimes possible if it is firmly bonded, but if it sounds hollow, is cracked or is coming away, it must be removed first. Covering failing render simply hides the problem until the new coat fails too. We tap-test the walls and explain whether removal is needed. Removal adds time and cost but gives a sound base.
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
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.
How much does it cost to render a house?
Rendering a typical 3-bed semi costs £9,100–£21,000, including scaffolding and preparation. As a guide, allow around £60–£120 per square metre of wall plus fixed costs for scaffolding and set-up. Sand and cement is the lowest-cost system, while silicone thin-coat costs more but needs no painting. Removing old render or pebbledash first adds noticeably to the price. We confirm a fixed figure after the survey.
