Cost of Rendering a House
Rendering advice and prices
Rendering is a wall covering method used on external walls to protect the bricks or blocks. The difference between plaster and render is simply that plaster is applied to internal walls, while render is applied to external walls. There are many different styles of render, but the main ingredients are cement, sand, and water. Lime is sometimes added especially when rendering older properties. Different proportions of cement, sand and water are used in rendering and plastering, render has more cement and coarse sand, whereas plaster mixtures use fine sand and less cement for a smoother finish that’s easier to paint and decorate on.
Homes are typically rendered because it is not possible to achieve a suitably weatherproof finish with just the stone or brick work. Renders can also be used when the brickwork has been damaged and rendering is the cheapest way to make the wall weatherproof again.

Typical rendering costs
|Job Description||Duration||Material Cost||Labour Cost|
|Small bungalow no scaffolding required||4-5 days||£1200||£1000|
|3 bed detached property including scaffolding||5-8 days||£2700||£1600|
|Detached house with scaffolding||1-2 weeks||£2500||£2350|
All of the above costs and durations are averages only and will vary depending upon location, complexity of job, etc.
Things to consider
Rendering external walls is labour intensive so already expensive, plus you will require access and safety equipment, usually scaffolding towers, which adds to the overall costs (unless you live in a bungalow). The type of render you choose will also affect price, with anything other than standard render being more expensive, so pebble-dash, for example, will cost extra. A standard rendering job will entail removing any existing render, key and repoint the brickwork, then apply new render in two coats, a sponge finish, then usually masonry paint will be applied to prevent moisture penetration and extend the lifespan of the render.
The price will differ depending on where you live in the UK, regional price variations can be huge with jobs in and around London often being twice as expensive as jobs in the North. Lime render has been traditionally applied to walls built out of stone or rubble or low-quality porous bricks. The lime render does not create a moisture barrier like cement render, but rather acts like a sponge and absorbs the water to stop it passing through the walls. This moisture then eventually evaporates from the surface of the lime render when the weather gets warmer. Traditional buildings that have been lime rendered originally, will tend to experience penetrating damp if the lime render is replaced with cement render.
Sand and cement renders are much stronger and harder than lime render and are typically painted. With more focus being put on energy efficiency, external wall insulation is becoming a popular topic as by adding external wall insulation when rendering it is possible to reduce heat loss from the building in cold weather. External insulation takes up no space inside the building and is seen as a popular choice when there are no cavities to fill with insulation. The application is pretty simple, before the render is applied an insulant material is fixed to the wall, then this is rendered over.
Doing it Yourself
Everyone likes to save money and corners can be cut on many jobs, but one place you definitely don’t want to cut corners on is the walls that support your house! If the job isn’t done correctly then the render will fail after a few years and then moisture will start to penetrate the wall causing damp and even structural damage. So if you plan on rendering the walls yourself as a DIY project, then the key doing a good job is in the preparation.
You need to spend time getting the walls keyed correctly by cleaning them thoroughly then scoring lines into the brickwork, then washing off so the surface is clean and free of dust and the new render can adhere correctly. You should avoid rendering on extremely hot days (which shouldn’t be too difficult in the UK) as the heat will cause the cement to dry too quickly and if it dries too fast it will start to crack.
The perfect day to render is a mild and dry day without too much direct sunlight and no rain or frost. When mixing the render the sand needs to be washed first to remove any salts or special plasterers sand should be used. Waterproofer, PVA, plasticiser and some lime should all be mixed in the correct quantities which will depend on the weather and the wall being rendered.
- Render is a sand/cement mix that is applied to external brickwork
- Masonry paint is almost always applied to render to keep out moisture
- Render both protects the brickwork and adds a layer of insulation
- Properties which are two storeys or higher will need scaffolding to apply render
Hiring a Tradesman Checklist
- Always get at least 2 quotes before hiring.
- Never pay the full amount upfront.
- Get the quote in writing.
- For any payment you make, always get a receipt.
- On more expensive jobs, ask for references.
- Check if the tradesman is a member of any trades associations.
- Make sure the tradesman has public liability insurance.

I need fitting insulation and rendering a full end terraced house. I will provide all materials and I will rent the scaffolding all around the property. I need a few quotes because the job is nearly ready to start.
