A Guide to Rendering

A step by step guide on external rendering

If your house is looking a little run-down, or has just had some work done on the exterior, rendering is an excellent way to finish the look, or make a multi-material house more uniform. If you’re ready to make moves on applying rendering to the outside of your property, here are some things you might want to know.

Will I need planning permission?

Rarely. You may if your house is in a conservation area or is listed. One thing you will need to do is comply with building regulations, which, depending on the age of your property, may mean adding insulation in the cavity, or if the walls are solid, inside or outside.

Do I need to do anything before applying the plaster?

Yes. Have the walls surveyed to make sure they are structurally sound. You don’t want to spend all that time and money on a great finish just to have it fail because you missed a spot that needed a repair.

You’ll also need to consider extensions to elements of a facade which ‘jut’ out, like vents, window sills, and corners of door and window frames, as well as pipes. Then, position angle beads around the frames and corners of the wall to support a smooth edge for the plaster. If you had to add external insulation, it comes before the fabric mesh of render too. Depending on the type of wall you have, rigid insulation boards are applied with glue, or in some cases, mechanically fixed in place.

Various render systems come pre-painted and finished, available in a plethora of colours and finishes, ranging from smooth to rough. After all the plaster and masonry coats have been applied, you can put back the soil pipes and vents, and anything else you removed from the facade.

Cost and timeframe

Naturally, if you need professional help (which most people will), it’ll cost more. It will also depend heavily on the size of your house, and whether you need to apply external insulation. A good benchmark is this – for a 3 bedroom house that requires external insulation, you could end up paying between £6-8k, and the process, from start to finish, could take a month.
