The Challenge – Updating Existing Buildings With Coloured Render and Insulation

This homeowner in Clevedon wanted to transform the property’s exterior and improve energy efficiency at the same time. The existing exterior walls featured ageing render and dated cladding, leaving the house looking tired and uneven, which is common with older properties.

The brief was to remove the old finishes and create a clean, uniform look using a durable monocouche render system. Long-term performance, thermal performance, and minimal maintenance were key requirements, leading to a solution that combined external wall insulation with a modern coloured render finish.

Our Approach – One Coat Monocouche Render and External Insulation Systems

We began by protecting the surrounding property, including driveways, windows, and access areas, ensuring the job was completed cleanly and safely to the highest standards.

Existing rendered surfaces were prepared and primed using PRB Accrofix. A reinforcement mesh was applied, followed by a premium one coat monocouche render. This pre-mixed render is spray applied, weather resistant, and designed for long-run durability.

The existing cladding was removed and replaced with 50mm EPS external insulation boards, securely fixed to the masonry using adhesive and mechanical fixings. These insulating materials brought the façade flush and eliminated uneven detail. A basecoat with mesh was applied before finishing with a lightweight monocouche render chosen for its aesthetic appeal, flexibility, and reliable performance in Somerset weather conditions.

The Result – Improved Energy Efficiency and a Transformed Property Exterior

The finished project delivers a fresh, uniform exterior that has completely transformed the house. The combination of external wall insulation and coloured render has improved thermal performance, reduced maintenance, and enhanced the property’s exterior walls.

All works were completed in line with manufacturer render systems and include a full 10-year guarantee. The site was left spotless, the quality of workmanship exceeded expectations, and the upgrade has added long-term value and weatherproof protection to the property.
