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.
From Craigavon, Portadown and Armagh to the quieter corners of County Armagh, homeowners can book a free survey for external rendering. We look at the building, agree the scope, then send a quote in writing that fixes the cost of that scope. Work follows the rules for Northern Ireland, and our published range for Northern Ireland, £6,000–£14,000 with VAT, gives you a sense of budget before we visit.

Housing across 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.
Rural bungalows and detached homes commonly take extensions, loft rooms, driveways and fencing. Terraces suit rear extensions and window replacement, and rendered houses often need re-rendering or painting.
A moderate inland climate with frequent rain and winter frost, and low ground near Lough Neagh can be wet.
Planning and building rules in County Armagh
England, Wales, Scotland and Northern Ireland each handle planning a little differently. County 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.
The four stages
Free site survey
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for external rendering so the price reflects your home.
Quote in writing
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Plan and prepare
Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.
Build and hand over
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
What you can expect from us
Frequently asked questions
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.
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.

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.
