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.
If you live in Armagh and are weighing up external rendering, the starting point is a visit to measure up and talk through what you want, which costs nothing. We cover homes across BT61, and a typical project of this kind in Northern Ireland lands somewhere in the £6,000–£14,000 bracket, including VAT. The exact figure depends on size, access and the finish you choose.

Homes in County Armagh
Armagh city has Georgian buildings, many in local limestone, around its historic centre. Portadown and Lurgan, linked by the Craigavon plan of the 1960s, have Victorian terraces, post-war estates and newer developments. The countryside is dotted with detached rural houses and bungalows, often finished in roughcast or render.
A moderate inland climate with frequent rain and winter frost, and low ground near Lough Neagh can be wet.
Knowing the typical building types in County Armagh helps, but a survey of your own home in Armagh is what decides the right approach to external rendering.
Do you need permission in Armagh?
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Armagh comes under Northern Ireland, covered below, and we raise any questions with the council before your quote is finalised.
In Northern Ireland, re-rendering is usually treated as repair, but conservation areas and listed buildings are controlled.
Significant re-cladding or external insulation should be checked with building control under the Building Regulations (Northern Ireland).
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
What happens after you get in touch?
A visit to your home
Book a visit and we'll come to you. The survey covers measurements, the state of what's there now and any obvious constraints, so the price that follows is based on your actual home, not an average.
Quote in writing
We put everything into a written, fixed-price quote: the specification, what's excluded, staged payments and the expected time on site. Take whatever time you need to decide; there's no pressure to commit.
Booking the work
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 Armagh property.
The work itself
On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.
How we work
Common questions
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.
How long does rendering take?
Rendering a typical semi-detached house takes around one to three weeks. Scaffolding goes up first, then removal of old render, repairs, beads and mesh. Base coats need time to cure before the finish coat. Weather has a big effect, because render should not be applied in rain, frost or strong heat. We give you an expected programme with the quote.
How much does it cost to render a house?
Rendering a typical 3-bed semi costs £6,000–£14,000, including scaffolding and preparation. As a guide, allow around £60–£120 per square metre of wall plus fixed costs for scaffolding and set-up. Sand and cement is the lowest-cost system, while silicone thin-coat costs more but needs no painting. Removing old render or pebbledash first adds noticeably to the price. We confirm a fixed figure after the survey.
Which postcodes in Armagh do you cover?
We cover BT61, along with the rest of County Armagh. 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.
Do I need planning permission in Armagh?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Armagh is in Northern Ireland, so Northern Ireland's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
