ProGuard Exteriors completed an external wall insulation upgrade on a detached solid wall bungalow in Sutton, South London. The property previously had a white painted pebbledash finish and the homeowner wanted to improve energy efficiency, reduce heat loss through the external walls and achieve a cleaner, more modern exterior finish.

Overview

The project involved a detached bungalow in Sutton with solid walls and an existing white painted pebbledash finish. The property had limited thermal performance through the external walls, and the homeowner was looking for a practical way to improve year-round comfort while upgrading the appearance of the exterior.

Following a detailed assessment, ProGuard Exteriors recommended a 90mm EPS External Wall Insulation system supplied by EWI Pro. The system was selected to help reduce heat loss, improve energy efficiency and provide the property with a durable, low-maintenance finish.

Our Response

ProGuard managed the full supply and fit installation, including the enabling works required before the insulation system could be installed. This included window sill extensions, gate adjustments, electrical adjustments and gas adjustments, ensuring the new EWI system could be fitted correctly and finished to a high standard.

Once the enabling works and insulation installation were complete, the EPS system was finished with a premium silicone render. White silicone render was applied to the main walls to create a bright, clean appearance, while a grey finish was used below the DPC to add contrast and provide a neat, practical finishing detail around the lower section of the bungalow.
