External rendering is applying a protective, weather-resistant coating to the outside walls of a house, using sand and cement, monocouche or thin-coat silicone render, to give a smooth or textured finish that protects the masonry and improves appearance.
In Isle of Lewis, as anywhere in Highlands and Islands, the price of external rendering is driven mainly by size, materials and access. Across Scotland our guide sits at £6,700–£15,500 with VAT, but restricted parking, a narrow side passage or extra preparation can move the figure either way. That is why every price we give follows a visit to the house.

- Making good around pipes, vents and fixings, and a site clean-up
Homes in Highlands and Islands
Inverness has Victorian villas and terraces and large modern estates, while rural Highland homes range from harled stone cottages and croft houses to modern timber-frame kit houses, which are common across the region. Orkney uses local flagstone, and island and coastal communities mix traditional stone homes with newer bungalows.
Croft houses and stone cottages often need lime harling, re-roofing and window renewal. Bungalows commonly take extensions and loft rooms, and remote projects need careful planning for materials and access.
In Isle of Lewis, as elsewhere in Highlands and Islands, we take the building's age and construction into account before recommending anything, because both can change what is involved in external rendering.
Do you need permission in Isle of Lewis?
For anyone in Isle of Lewis, the relevant framework is Scotland's. The summary below is general, so we always contact the council about your address before putting a price in writing.
In Scotland, changing the external finish of a house in a conservation area or on a listed building needs consent; elsewhere, like-for-like re-rendering is usually treated as repair.
Large-scale re-cladding or external insulation can need a building warrant; like-for-like render repairs normally do not.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
The four stages
Free site survey
First, someone visits your home in Isle of Lewis to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Quote in writing
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for external rendering.
Dates and permissions
With the quote agreed, we book the work in and handle preparation: permissions where needed, building control notifications, material orders and access arrangements for your Isle of Lewis property.
On site to finish
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Questions about external rendering in Isle of Lewis
Which postcodes in Isle of Lewis do you cover?
We cover HS1, along with the rest of Highlands and Islands. If your postcode is not listed, get in touch anyway: our coverage is UK-wide, and we can usually arrange a survey wherever you live. Enter your postcode in the guide-price tool or contact form and we will confirm.
Can you combine external rendering with other work?
Yes. Because we manage several trades under one contract, we can plan external rendering alongside other work on your Isle of Lewis home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
Do I need planning permission to render my house?
Whether rendering needs planning permission depends on how it changes the appearance, your home's location, whether it is listed or in a conservation area, and which UK nation you are in. Rendering over brick may need permission in some places, while replacing existing render like for like often does not. Listed buildings need consent. We check the position before quoting.
Can you render over pebbledash or old render?
Rendering over existing pebbledash or render is sometimes possible if it is firmly bonded, but if it sounds hollow, is cracked or is coming away, it must be removed first. Covering failing render simply hides the problem until the new coat fails too. We tap-test the walls and explain whether removal is needed. Removal adds time and cost but gives a sound base.
How do I look after silicone or monocouche render?
Through-coloured render needs little upkeep. Check it once a year for cracks or damage, especially around windows and pipes, and keep gutters clear so water does not run down the walls. If green algae appears on shaded walls, a specialist render cleaner applied with a soft brush or low-pressure wash removes it. Avoid high-pressure jet washing, which can damage the surface.
