House Rendering Costs

Material Costs, Labour Fees and Time Frame Estimates for House Rendering External Walls

Costs for External Rendering

If you have a semi-detached 3-bedroom house, building a scaffold will require removing any existing render, getting the surface prepped up including keying, stabilizing, and brushing, as well as applying double layers of smooth render. This could cost about £3000 to £4000. 

Note that this cost does not yet account for the painting. If you want to get pebbledash for a finish, expect to add £1000 to the cost. If you wish to have it painted afterwards, expect to add at least £500 more since the task isn’t going to be an easy one to carry out. The job will require the use of a brush to press into the render to ensure good coverage. 

It’s common for renderers to charge on a per job basis instead of charging a daily rate since there are several days that they will need to wait first to allow the finish to properly dry before the next stage of the rendering can be carried out. If you have a semi-detached home with 3 bedrooms, a complete house rendering job could take about an entire week to get done. 

Cost Breakdown

Hiring a house rendering company to get your external walls fully rendered could cost up to £3750. This is for a semi-detached home that requires a smooth finish. Of that, £375 covers for the materials, £2250 covers for the tradesmen fees and £1125 will pay for the costs for erecting the scaffolding. 

What does the Rendering Job Entail?

Render is a mixture of cement and sand that is then applied to the exterior brickwork. It is intended to waterproof and cover up old bricks when they start letting moisture in. Today, it is now being used as alternative finish for external walls. Render is often applied as dual coats, with the second coat being either pebble-dashed or smooth.   

After house rendering, masonry paint can now be applied next to help ensure that moisture is kept out. This is important as moisture that seeps through the render can freeze in the winter which could break the render and cause it to fall off.  Scaffolding will need to be erected then any existing render will be removed, followed by brickwork keying, and the getting the two render coats applied. 

Before the render is applied, the brickwork must be assessed first to ensure that it is still in good condition. If not, repointing is necessary and the damaged bricks will have to be replaced. Do remember that the quote from the tradesman is not going to include repainting quotes. So, this will be a related job that you will need to budget for. There may be a need to remove the soffit boards and fascia before the actual rendering so if they are in dire need of replacement, make sure to do so too to maximize the labour costs. 

Make sure to carefully check the walls before rendering, make sure that any necessary repairs are carried out for any structural defect or the new render is just going to end up failing.  Roofline products and other external items will also need to be removed, along with satellite dishes, alarm boxes and other external details. If applying wall insulation, they will have to be in of slab or rigid board forms, though this depends on the wall type and budget that you’re willing to spend.

Planning Permissions

Planning permission is generally not necessary when rendering your external walls, with the only exception being when the property is a listed building or is located within a known conservation zone. However, there may be a need for you to comply with specific Building Regulations if you expect to render a considerable part of your home. 

Render vs Cladding vs Pebbledash vs Roughcast

Cladding is the skin of materials that are applied for their protective and decorative properties. A variety of materials can be used for this purpose including uPVC and materials made from timber which require little to no maintenance. Render also does the same thing although most of the materials used for cladding are generally considered dry ones and are usually fixed mechanically through fittings or screws. Render, meanwhile, is a wet coat that gets applied to the exteriors, very much like plaster. 

Pebbledash and roughcast are just rendering that are reinforced with gravel, shells, and pebbles that are aimed to create an outer layer that is hard-wearing. These finishes are usually seen outside of homes in coastal areas as they are quite effective against the rough elements. It used to be a very popular option in various housing authorities in the 70s to the 80s, thanks mainly to its cheap application and maintenance. They are no longer as popular today, possibly due to the fact that they are considered old-fashioned. 

Your options will be largely dictated by the amount of money that you’re willing to spend. Sometimes, the approval of the local council will have to play a crucial role in your decision as well. Note that most of those options that promise low maintenance tend to require an extensive application. However, you do get the benefit of cost-effective upkeep moving forward. Traditional rendering is the most ideal if what you’re looking for is a cheaper choice at £60 a square metre. uPVC cladding costs less at £50 a square metre and natural stone could cost around £100 a square metre. If you want to go for artificial stone, expect the costs to be around £70 a square metre. Expect to pay about £90 a square metre if going for cladding made from hardwood timber. If you’re looking for the cheapest option there is, you can go for masonry paint that is weather-proof which could cost 15 for three coats. Unfortunately, this is generally considered less durable. 

Coloured External Rendering

If you’re looking for a practical yet decorative alternative, coloured external render is an alternative to consider. There are a variety of colours that are available for you, which makes it easier to find one that will suit your taste and the style of your home. Choosing the right colour should be easy enough considering your options are plenty. Note that you’ll need a primer as a base coat before applying the coloured render.  It’s common for these renders to use fiberglass mesh that is embedded within so they can effectively bond with the render. The primer needs to match the render colour as well then the coloured render can finally be applied. Among the numerous coloured render types you can choose from include acrylic, silicone, monocouche scratch and mineral render. Silicon render is available in a variety of colours and is known for being able to repel dirt, water as well as growth like kitchen and moss. It is also quick and easy to apply since it comes in a bucket, ready to use.
