Scaffold, tower or poles? How high render is reached for cleaning
Why access decides the method and the price
Cleaning the wall itself is often quicker than getting safely to it. A bungalow with open gardens is easy to reach. A three-storey townhouse on a pavement, with a conservatory at the back, is not. Contractors must plan work at height safely under the Work at Height Regulations 2005, and the safest suitable method should be chosen, not just the cheapest.
The main access options
| Method | Typical reach | Best for | Drawbacks |
|---|---|---|---|
| Water-fed or spray poles from the ground | Two to three storeys | Most houses, soft washing | Less control for stubborn spot cleaning |
| Ladders | Short, low-risk tasks | Small areas, sills, gutters | Not suitable for long jobs or heavy equipment |
| Mobile tower | Around one to three storeys | Small elevations, end walls | Needs firm level ground and assembly |
| Cherry picker or MEWP | Several storeys | Tall walls, quick access | Needs space for the vehicle, may need a permit on the road |
| Scaffolding | Any height | Large jobs, repairs, repainting | Most expensive, takes time to erect, may need a licence |
Ground-based cleaning with poles
Much modern render cleaning is done from the ground. Telescopic poles carry hoses or spray lances up to the wall, and a biocide or cleaning solution is applied at low pressure. Rinsing is also done from the ground. This keeps operatives off ladders and is usually the most cost-effective method for typical two-storey houses.
Poles work best where the wall can be reached at a reasonable angle from the ground. Obstacles such as conservatories, extensions, steep banks or narrow passages can make this harder.
Conservatory roofs, glass canopies and flat extension roofs must never be leaned on or walked on unless they are designed for it. Contractors usually work around them from the ground or from a tower set up beside them, and protect the glass from overspray while the wall above is treated.
Towers and cherry pickers
Mobile towers are useful where a section of wall needs closer work, such as rust stain treatment, small repairs or careful cleaning around windows. They need firm, level ground and should be erected by someone trained to do so.
Cherry pickers and other mobile elevating work platforms reach high walls quickly without the cost of scaffolding. They need hard standing or ground protection and enough space to set up. On a public road, the operator may need permission from the highways authority and to put out signs and barriers.
When scaffolding makes sense
Scaffolding is the most expensive option and is rarely needed for cleaning alone. It becomes worthwhile when the render is also being repaired or repainted, when the building is very tall, or when other work such as roofing, gutter replacement or window fitting is happening at the same time. Sharing scaffold between trades can save a lot of money.
- Check how long the scaffold will be up and what the hire period covers
- Ask about scaffold alarms or ladder guards for security
- Confirm who arranges any pavement licence
- Make sure neighbours are told if scaffold crosses a boundary or shared path
Working near neighbours and boundaries
On terraced and semi-detached houses, access to the side or rear wall may only be possible from a neighbour's garden or a shared path. There is no general right to go onto a neighbour's land for cleaning, so permission is needed. A polite conversation in advance usually works. Explain how long it will take and how plants, cars and windows will be protected from overspray.
If the wall is a party structure or the render sits partly on a neighbour's property, agree in advance what will be cleaned and who pays for what.
How access affects your quote
- Ground access to all walls: usually the lowest price
- One awkward elevation: a little extra time or a tower
- Pavement-fronted terraced houses: may need a licence and signage
- Three storeys or more: often a cherry picker or scaffold
- Cleaning combined with repainting: scaffold is often worth it
When asking for quotes, mention the number of storeys, whether there is a conservatory or extension, and whether any walls can only be reached from a neighbour's land. Photos of every elevation help a contractor price accurately.
It also helps to say where the nearest outside tap is and whether there is somewhere to park a van close to the house. Long hose runs and distant parking add time, and on busy streets parking restrictions can affect which day the work is booked.
Frequently asked questions
Can render be cleaned without scaffolding?
Yes, in most cases. Typical two-storey houses can usually be cleaned from the ground with telescopic poles and low pressure spray equipment. Towers or cherry pickers are used where poles cannot reach well. Scaffolding is usually only needed for tall buildings or when cleaning is combined with repairs or repainting.
Do I need my neighbour's permission for render cleaning?
If any part of the work needs access from your neighbour's land, you need their permission, as there is no general right to enter for cleaning. Even when working from your own land, telling neighbours in advance is sensible, because overspray and rinse water can drift. Agree arrangements for protecting their windows, cars and plants.
Why is render cleaning more expensive on a three-storey house?
Taller walls take longer to treat and rinse, and often need more specialist access equipment such as a cherry picker or scaffold, which adds hire costs and setup time. Safety planning and any road permits also add time. The cleaning itself is similar, so the extra cost is mainly about safe access to the upper walls.
