Green algae and black mould on communal steps are more than an eyesore. They are a genuine slip hazard, and one that gets worse every time it rains. At Canterbury House on The Reeds in Watford, our team carried out targeted jet washing to strip away mould and restore safe footing on the communal areas. This report was prepared for Ms Jennifer Mann, Senior Property Manager at Rendall & Rittner Ltd.
The Safety Issue Behind the Stain
Mould and algae thrive in the damp, shaded spots common to communal entrances and stairways. As they spread across steps and paths, they create a slick film that becomes dangerously slippery underfoot, especially in wet or icy weather. For a managing agent, that is a clear health and safety concern. Mould removal through professional cleaning is one of the simplest ways to reduce that risk.
How We Cleaned It
We treated the communal entrance, the steps and the path leading to them, using a method designed to remove biological growth at the root rather than just on the surface:
- Manual scrubbing to loosen ingrained dirt and break up established mould.
- A light chemical treatment to kill off algae and mould without harsh or environmentally harmful products.
- A strong jet wash to flush the surface completely clean.
Treating the growth, not just rinsing it, is what stops it returning within weeks.
The Result
The before and after pictures show a significant transformation. The steps and path at Canterbury House were left clean, bright and, most importantly, far safer to walk on. Residents get communal areas they can use with confidence through the wetter months and a brighter look heading into spring and summer.
Why Anti-Slip Cleaning Matters
Communal steps are one of the most common sites of slip-and-trip incidents in residential blocks. Regular anti-slip pressure washing keeps mould and algae from building up in the first place, protecting both residents and the managing agent's duty of care. It is preventative maintenance that pays for itself the first time it stops an accident.
Frequently Asked Questions
Does jet washing remove mould permanently? Jet washing combined with a light treatment removes existing mould and slows regrowth. In damp, shaded areas, a regular cleaning schedule keeps it from re-establishing.
Are your cleaning products safe for residents and pets? Yes. We use eco-friendly methods and natural products wherever possible, so communal areas are safe to use once dry.
How quickly can steps be used after cleaning? Communal steps are typically safe to use again the same day, once surfaces have dried.
