Traditional roughcast render that protects your home from North West weather. Applied by specialist rendering contractors with over 45 years of experience across the North West.
Roughcast render - sometimes called wet dash or harling - is a traditional external wall finish that has been used on British homes for well over a century. It consists of a sand and cement base coat topped with a finish coat containing aggregate, which gives it its distinctive textured appearance.
The rough, pebbled surface is not merely decorative. It's highly functional: the texture breaks up rainwater, preventing it from sheeting down the wall and penetrating the substrate. This makes roughcast particularly well-suited to the wet, windswept climate of North West England, where driving rain is a regular feature of autumn and winter.
At FX Render Systems, we apply roughcast render to a high standard using quality materials and time-tested techniques. Every job is prepared properly, applied carefully, and finished neatly - because the longevity of the system depends on the quality of the application.

The textured aggregate surface of roughcast render is specifically designed to shed water quickly and resist the driving rain that's common across North West England. It's been protecting British homes for generations.
When applied correctly, roughcast render is one of the most long-lasting external finishes available. A properly installed system can protect your walls for 20–30 years with minimal maintenance.
Roughcast is particularly effective at concealing uneven brickwork, patched repairs, or ageing stonework - delivering a uniform, consistent finish across the whole elevation.
Compared to some premium render systems, roughcast offers excellent value for money without compromising on protection. It's a practical, hardwearing choice for budget-conscious homeowners.
Roughcast render has a long history in the North West of England. It suits the character of the region's housing stock and is widely accepted by local planning authorities.
Once applied and cured, roughcast render requires very little upkeep. An occasional clean and periodic inspection is all that's needed to keep it performing well.

Roughcast render is a versatile system that suits a wide range of property types common across Wigan, Bolton, Manchester and the surrounding areas. It's particularly well-regarded for older solid-wall properties where weather protection is the primary concern.

A quality roughcast render job starts well before the first coat goes on. Preparation is everything - and it's where many contractors cut corners.
We inspect the existing substrate, identify any areas of loose or damaged masonry, and assess the condition of existing render if present. Any defects are made good before work begins.
The wall surface is cleaned, any loose material is removed, and the substrate is treated to ensure proper adhesion. Window and door reveals are protected with masking and dust sheets.
A base scratch coat is applied to the wall and combed to create a key for the finish coat. This layer is left to cure fully before the next stage.
The roughcast mix - comprising sand, cement, and aggregate - is applied and worked to achieve the characteristic textured finish. Colour can be added at this stage if required.
Reveals, sills, and edges are carefully finished. Any protective masking is removed and the surrounding area is thoroughly cleaned.
The render is left to cure properly. We carry out a final inspection with you before handover, and your 10-year workmanship guarantee is issued.
Every roughcast rendering job we complete is backed by a 10-year workmanship guarantee. We're fully insured with public liability and employer's liability cover, and certificates are available on request. We stand behind our work - long after the scaffolding comes down.
