What is Rendering?

Rendering, when applied to buildings, refers to the application of cement to external and/or internal brick or concrete walls in order to achieve a smooth or deliberately textured surface. Also called cement rendering or solid plastering, rendering work need to be carried out by highly experienced and qualified plasterers in order to create a top quality finish.

You can see some of our professionally finished work in our Portfolio.

Why Render?


The number one reason for rendering a property is of course to improve the look. Rendering can improve the waterproofing and fire rating of a building, but the primary reason for doing it is aesthetic. Adding a render coat can really brighten up and refresh any property or building.

Penetrating Damp Issues

Another reason people choose to render their homes is to deal with penetrating damp issues. Some forms of brick can be liable to damp if exposed to the elements over prolonged periods. By adding a layer of render to the outside wall of a property, we can prevent this form of damp occurring.

Improve thermal performance

Rendering your property will provide some slight insulating benefits on its own, but if you are rendering, it is a great time to consider full external insulation. Luckily, that’s another service we have over 25 years experience in installing! Find out more here.

So for any rendering in Coventry, the Midlands and beyond – look no further than Altmor.
