Powerwash Contractors provides a careful, specialist render cleaning service that brightens exterior walls without damaging the surface. We’re based in Swindon and can help homeowners remove years of grime and weather-related staining, so their property looks clean and well-kept again.

Render is porous, which means it naturally attracts algae and dark patches that become more noticeable over time. We use a low-pressure soft-wash system designed specifically for render, along with targeted treatments that break down stubborn stains without damaging the material. Our service is safe and effective on most render surfaces, including K-Rend, monocouche, silicone, acrylic or painted render, we select a method that suits your wall type and condition.

We cover homes across Wiltshire and the surrounding areas, using commercial-grade equipment and reliable cleaning products for a fresh finish. No two houses are the same, and we tailor the strength of each treatment to make sure your render is cleaned safely and effectively.
