Protecting What Matters. Finished to Last.
Rendering is more than just a coat on the outside of your home — it’s your property’s first line of defence against the weather. At Adfer Cymru, we take rendering seriously. Whether you’re updating tired walls, repairing failed systems, or starting from scratch, we deliver high-quality finishes that look great and perform for years to come.

Built for the Welsh Weather
South Wales sees its fair share of rain — and if your render is cracked, blown or holding in damp, it won’t just look tired, it’ll let the water in. We work with breathable, weather-resistant systems that suit the building type and the local climate. That means protection that actually works — not just a fresh face.
Heritage-Friendly Options
Rendering older stone or brick properties needs a gentler touch. We use traditional lime renders for solid wall homes that need to breathe. Modern cement-based systems can trap moisture and cause damage over time — we’ll always recommend the right solution, not just the quickest one.
Every Detail, Done Right
We don’t just slap on a coat and move on. From proper preparation and reinforcement mesh to clean beadwork and crisp corners, everything is done with long-term performance in mind. A clean finish isn’t just about looks — it’s about durability, too.
Need More Than Just Rendering?
Rendering often goes hand-in-hand with other improvements — insulation, repointing, roofline work, or full renovations. We can take care of the whole job, project managing trusted trades and delivering a consistent, high-spec finish from start to end.

Frequently Asked Questions
What's the best type of render for my home?
That depends on your property. Modern cavity wall homes usually suit silicone or monocouche renders, while older solid wall homes often need lime render to stay breathable. We’ll assess your building and recommend the best solution — not just the most common one.
My current render is cracked and falling off. Do I need to remove it all?
In most cases, yes. Cracked or blown render traps moisture, damages walls, and can’t be patched reliably. We’ll strip it back, inspect the surface, and apply a fresh system that’s built to last.
Can rendering stop damp?
It can help — especially when it replaces failed or non-breathable systems. But the key is choosing the right materials. In older homes, we use breathable renders like lime or vapour-open silicone to allow trapped moisture to escape, rather than sealing it in.
What's the difference between sand & cement and monocouche render?
Sand and cement is the traditional method — strong and cost-effective, but more prone to cracking without reinforcement. Monocouche is a modern, through-coloured render applied in one coat, which saves on painting and provides a crisp finish. Each has pros and cons, and we’ll advise on what suits your property and budget best.
What is silicone render, and is it worth the extra cost?
Silicone render is a flexible, water-repellent finish that resists cracking and stains. It’s great for wetter areas like South Wales and offers long-term performance with minimal maintenance. It costs more upfront, but often pays off in longevity.
Can you insulate my walls before rendering?
Yes — we install external wall insulation (EWI) systems that improve energy efficiency and reduce heat loss. These systems are then finished with a render coat. It’s an ideal solution for homes with poor EPC ratings or cold, solid walls.
How long does rendering last?
Yes. Adfer Cymru is a member of the Federation of Master Builders, and we hold full public liability insurance. Your home and project are in safe hands.
Will you protect my windows, garden and driveway during the job?
How long does the rendering process take?
That depends on the size of the property and the system used. A small house with monocouche render might take 4–5 days, while larger or lime-based jobs may take longer due to drying times. We’ll give you a clear schedule before starting.
Do I need planning permission to render my house?
Usually not — but if your property is listed, in a conservation area, or you’re changing the appearance significantly, it’s worth checking with your local authority. We’re happy to help you navigate the process if needed.
