Overview of House Rendering

House rendering is a process of coating the exterior walls of a home with material that has several practical and aesthetic benefits:

  • Stops further deterioration of brick and some other exterior siding materials
  • Protects the house from moisture penetration that might otherwise cause rot and mold
  • Slightly increases thermal insulation, though this isn’t a cost-effective reason to render a house
  • Beautifies the house’s exterior, especially if the home is looking aged
  • Adds value to a home, should you choose to sell
  • Lasts 15 to 40 years depending on the type used

Can a new house be rendered? Yes, sometimes builders choose rendering as the exterior finish because it is cost-effective and quite durable.

Can a house be re-rendered? They often are. The cost to re-render a house can be significantly higher than the first rendering because surface repairs are usually needed before applying fresh rendering. In some cases, the old rendering must be scraped off completely.

Types and Costs of Rendering Options

House Rendering Cost by Type & Location
House Rendering Cost per m2 by Type
North Midlands London/South
Sand and Cement £25 – £33 £30 – £36 £35 – £42
Monocouche £35 – £48 £44 – £60 £50 – £64
Acrylic or Silicone £48 – £60 £52 – £64 £58 – £70

Note: The average cost to re-render a house is £10 – £20 per square metre higher in every category based on how much preparation or removal of old rendering is needed.

You have three material options. The one you select is the most important factor in the average cost to render a house.

1. Sand and cement rendering is the most traditional of the three house rendering types. It is available pre-mixed or in bags for mixing with water on the job site. It has the advantages of being affordable and easy to paint. But that’s the downside too – It must be painted periodically.

Tradesmen are familiar with sand and cement rendering application, so problems are rare with it going on the walls. Two or three layers are applied depending on the exterior wall conditions. Sand and cement rendering lasts 10-20 years depending on wall condition, climate and whether the paint is maintained.

2. Monocouche is the newest type of render. It’s mid-priced and quite durable. This rendering material is supplied in bags, mixed on the job and applied to the walls of your house with a trowel. The nice thing about it is that colour is added to the mix, so no painting is required.

You have several colour options too. Two layers are applied. Expect monocouche rendering to last up to 25 years.

3. Acrylic or silicone or other polymer rendering is used for repairs or for re-rending a home on which the old rendering is starting to age. Clear rendering enhances the looks and durability of the underlying material. Coloured options are available too. By the way, acrylic is slightly less expensive than silicone and other polymers, but not quite as durable. It lasts 20-30 years. Silicone and other polymers have longevity of 25-40 years depending on wall conditions, climate and other factors.

House Rendering Cost Factors

These will give you a good idea of what your cost to render a house will be.

  • Rendering Type – As noted above, there is a significant price difference among the three. However, keep in mind that if you choose sand and cement, you’ll need to re-render the house sooner plus the rendering will have to be painted every 3-6 years. That means long-term costs might be higher. If it is in the budget, choosing one of the more durable types will reduce long-term costs and make your home more attractive to buyers.
  • Prep Work – If old mortar needs tuck pointing or cracks must be filled before the rendering is applied, cost will be higher.
  • Ease of Access – Where shrubs or a conservatory or other obstacle must be worked around and over, cost can be slightly higher. This is because the job will take longer, and time and materials are the two key elements of a house rending cost quote.
  • Whether Scaffolding is Needed – If you have to hire scaffolding as a separate cost, the total price will be higher.
  • Time of Year – Summer is the ideal time to apply rendering because the air is drier and warmer than at other times, so it cures more effectively. These conditions make summer the busy time, so house rendering cost quotes might be higher than at other times of the year. You might get estimates that are more competitive at other times, as long as weather conditions allow the work to be completed. Regardless of when you get house rendering cost quotes, it makes sense to request them from multiple companies that know they are competing for the job.
  • Where you Live – It’s no surprise to you that if you live in or around London or in the Southeast, prices are higher than in the Midlands and North.

House Rendering FAQs

Here are common questions and their answers.

When is the best time to render a house?

In terms of the season, summer is best because warm, dry air facilitates the curing of the render. This is true as long as it isn’t a heat wave. If the air is too hot and dry, the rendering might dry too fast, not curing properly.

Secondly, the best time to render your house is before the brickwork falls into disrepair. If it does, you’ll have costly preparation work to do before rendering can be applied. It isn’t a replacement for loose or missing mortar.

 How long does it take to render a house?

  • Terraced house: 3-4 days
  • 3 bedroom semi-detached: 4-5 days
  • 2 bedroom detached: 4-6 days
  • 3 bedroom detached: 5-8 days
  • 4 bedroom detached: 6-10 days

How much to render a terraced house?

How much to render a 3 bed detached house?

How much to render a 4 bed detached house?

How much to render the front of a house?

Choosing a House Rendering Company

It’s always a good idea to get quotes from 3 contractors that know they are competing. Then interview each to determine the crew’s experience. Look at homes it has recently rendered, and if possible, houses completed 5-10 years ago to see if the rendering is holding up.

Then select a rendering tradesman based on work quality and cost. If you select based on low cost only, you might end up getting a shoddy job that cuts corners. It’s worth paying a little more to get a proven professional to do the work.
