We recently updated our price guide for internal wall plastering (you can find that price here) so we thought it would a good time to take another look at external wall rendering.
Wall render is traditionally a mixture of sand, cement and other aggregates which are then applied to external walls to form a protective layer that is an alternative to brickwork or cladding. While the cost of sand and cement is fairly cheap, the work needs to carried out by specialists and scaffold is often required.
Also, there are other options such as silicone and acrylic render systems. But, how much does wall rendering typically cost?
Top tip: for new visitors to our site – this is just one dozens of insightful home improvement prices we have created for you. Join the many thousands of other people who have saved money by exploring our recently updated full price list here.
We created this page as a guide so you can get a rough idea of how much this type of work costs. Obviously, every job is different and things like location, the age of the property and the amount of scaffold required will affect the price.
Also, make sure you read our section titled “Additional Costs” as there are some hidden costs that you may need to account for to meet current building regulations
Don’t Confuse Render With Plaster
Render is almost always applied outdoors, plaster is a different material and is used indoors.
For internal plastering prices check out this separate price.
Three Different Types of Render to Consider
There are three different types of render you can use on your external walls, each is priced differently;
- Sand and Cement – this is the traditional method of applying two layers of a sand and cement mixture to the walls. Once dry, the wall is usually painted with two or three coats of a good quality masonry paint.
- Monocouche – this is a cement based product that has a coloured pigment added to the mixture. One finishing layer is installed on top of a base layer, you don’t need to paint the surface.
- Silicone – this is the most expensive type of render but has many benefits, it’s flexible so shouldn’t crack and it’s also breathable so can help prevent wall condensation. Like the Moncouche, this is also a “through colour” so no painting is needed, just a wash every few years or so.
We Have Two Render Prices For Comparison
Below you will find two example wall rendering prices for your consideration:
1) Small Terraced House Sand/Cement Finish
This price is for a sand and cement finish to a small terraced property. The existing render needs to be removed and disposed of, a sand and cement render is then applied in layers and allowed to dry. Finally, the dried wall is painted with two or if required, three coats of external wall paint.
We assume there are approximately 50 square metres of the wall to be rendered:
|Remove and dispose of existing render||£600.00|
|Apply layer of new S/C render inc primer, beads/trims etc||£2250.00|
|Paint, 2 to 3 coats||£600.00|
2) Semi Detached House With Coloured Silicone Finish
The price you can see displayed in the table below is for a typical semi-detached house with three sides. The existing wall render will be removed and two layers of render applied, the final layer being a silicone coloured product.
We assume that this semi-detached house has 100 square metres of an external wall:
|Remove and dispose of existing render||£1000.00|
|Apply layers of new render with coloured silicone finish, inc primer, beads/trims etc as required||£6000.00|
Added Extras to Consider
Scaffolding costs can vary by a lot, it’s not just the height of the scaffold that needs to be considered but it’s location. Erecting this access equipment over roads and footpaths is more pricey than on private land. Obstacles such as conservatories will need to be bridged and this can add to the final price.
Insulation – if you intend to replace or install render to 50% or more of the walls on your house, building regulations stipulate that must ensure that the wall insulation meets current requirements. If you have a cavity wall, this can be filled at extra cost or if you have a single skin wall, you can have an insulation board installed between the wall and the render. Cavity wall insulation is fairly cheap and easy to install but the insulation-backed render is very expensive, expect to pay north of £110 per square for the boards, render and all the necessary beads and trims. The reason it’s so expensive is that the wall will be around 100mm thicker so window sills need to be extended and similar alterations made.
What About Patch Repair Costs?
This depends on the type of render that is currently on the wall, as well as its condition. For Monocouche and silicone rendering, patch repairs are not advised, you would need to replace, or at least apply an extra layer to the entire wall to ensure a consistent colour throughout. For old fashioned sand/cement render, you may be able to chisel off the damaged section, replace as required and then apply a coat of paint.
As a general rule of thumb, if the existing sand/cement render issue is due to an “event” such as a water leak that has blown the render off the wall, or perhaps damage caused by an impact, then a repair should be possible. If however, the render is in generally poor condition then patch repairs are usually a waste of time and it would be better to replace the whole wall.
Don’t forget; the cost of the wall rendering isn’t just the labour and materials but also arranging for the scaffold, skip hire, finishing off with paint etc. It can be a false economy to keep repairing an old wall in patches and in most cases, it’s best to “bite the bullet” and get the whole lot done.
We have a guide to mortar mixes which provides details of the ideal amount of sand, cement, lime and other additives that are mixed together to create render.
