Herts Pressure Washing are Hertfordshire’s leading Soft Wash and Steam Cleaning Specialists


We only use the ‘softwashing’ method to clean render which is a safe and eco-friendly way of removing organic matter and atmospheric pollution from exterior render. Our soft washing and pre-treatment render cleaning systems will:

  • Remove unsightly black mould and algae.
  • Restore the render to a new state.
  • Gently remove pollutants, algae, and stains.
  • Protect your property from further damage due to moss, lichens, and mould growth.
  • Prevent dampness from becoming an issue.
  • Allow the rendered walls to breathe as designed.

We use low-pressure units to gently clean render, restoring the surface to its natural new state, while not harming the building’s substrate. Our special ‘softwash’ approach completely removes the need for any pressure washer, instead relying on gently soaking the surface with a biocidal chemical at no more pressure than your garden hose. Learn more about our Softwashing technique.

We were looking for a company that could clean our render as we had previously tried doing it ourselves, only to make it look far worse. Alex came and looked at the job within a few days, gave us a very reasonable price whilst explaining the process and left us happy that he knew what he was doing. He turned up on time, got on with the job, and most importantly, made our render look brand new again! I would without doubt recommend Alex and team if looking to get render cleaned.
