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.
Aberdare sits within our coverage for external rendering, as do neighbouring Rhondda, Merthyr Tydfil and Tonypandy. Before giving a price we want to see the property: the condition of what's there now, the access, and anything that might need extra work. The guide range for Wales is £6,400–£14,500 including VAT, and your written quote will spell out exactly what that covers.

Local housing and external rendering
The Rhondda, Cynon and Merthyr valleys are lined with stone terraces built for mining families, stepped along steep hillsides. Pontypridd, Caerphilly and Merthyr Tydfil have Victorian centres, and Bridgend has grown with large modern estates alongside interwar and post-war housing.
The valleys get heavy rainfall and steep, sloping sites are common, so drainage, retaining walls and render specification matter.
Whatever era your Aberdare home dates from, we plan external rendering around how it is actually built rather than a one-size-fits-all specification.
Permissions for external rendering in Aberdare
Each UK nation sets its own consent rules, and Aberdare is in Wales. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.
In Wales, rendering or cladding may need planning permission in conservation areas, and listed buildings need consent.
Building Regulations in Wales can require insulation upgrades when a large part of an external wall is renovated.
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?
Survey and measure
A free survey comes first. It gives us what we need to price external rendering properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
The quote arrives in writing, not over the phone. It covers the full scope, the finishes you've chosen, any exclusions and the payment schedule, with a fixed price tied to that specification.
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.
On site to finish
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.
How we work
External rendering in Aberdare: questions
Do I need planning permission in Aberdare?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Aberdare is in Wales, so Wales'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.
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 much does it cost to render a house?
Rendering a typical 3-bed semi costs £6,400–£14,500, 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.
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.
What happens at the survey?
We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from external rendering, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
