Render & Exterior Wall Cleaning

Rendered and painted exterior walls are prone to green algae growth, pollution staining, and general discolouration — particularly on north-facing elevations. Our exterior wall cleaning service uses soft-wash techniques combined with biocidal treatments to safely clean render without causing damage.

Soft washing is gentler than standard pressure washing and is the recommended method for K-Rend, monocouche, pebble-dash, and painted surfaces. The biocide treatment continues working after we leave, killing algae and moss spores at the root to keep your walls cleaner for longer.
