Commercial Pool Mould & Algae Removal, UK
A busy indoor swimming pool facility contacted us regarding extensive mould growth and algae build-up on tiled walls and surrounding poolside surfaces. With daily bookings and member sessions scheduled, the pool could not be shut down for an extended period. The project required a fast turnaround, strict contamination control, and seamless coordination.
The Challenges
Our inspection identified:
- Heavy mould growth on the upper tiled walls
- Green algae build-up
- Slippery poolside flooring
The key concerns were:
- Limited shutdown window
- Zero contamination risk to the pool water
- Protection of the filtration and chemical balance systems
- Immediate reopening once the works were complete
Our Strategic Approach
1. Containment & Contamination Control
Before starting work, we implemented strict protection measures:
- The pool water surface is fully covered and sealed
- Containment barriers were installed to prevent airborne spread
- Controlled application methods
- Runoff management systems to prevent chemical entry into the pool
Extra care was taken for our work throughout the project to ensure no debris, chemicals, or mould spores entered the pool water or plant systems.
2. Coordinated Time-Sensitive Execution
To meet the restricted closure period:
- Immediate on-site risk assessment
- Equipment and materials prepared in advance
3. Specialist Multi-Step Remediation Process
Targeted Anti-Fungal & Algaecide Treatment: Precision-applied commercial-grade solutions eliminated mould and algae at the source.
Controlled Rinse & Drying: Ensured all surfaces were clean, residue-free, and safe before reopening.
4. Post-Clean Water Testing & Collaboration
Upon completion, we worked closely with the pool's on-site maintenance team to:
- Conduct full water quality testing
- Confirm no chemical imbalance
- Verify filtration system integrity
- Ensure chlorine and pH levels remained within safe operating range
This collaborative approach ensured the facility could reopen immediately with full confidence in both hygiene and water safety.

“A huge thanks to Clean N Bright who carried out a large scale clean of our stands at Doncaster Racecourse. Not only did they carry out the work at short notice, but they did so efficiently and with professionalism. When I needed assistance with other areas of work, they rose to the challenge.”

“Clean N Bright is an amazing company. We worked with them over the summer to clean our entire auditorium, which is a feat in itself, at 620 seats. The team were absolutely incredible, they went above and beyond. It’s really great to work with a local company that cares so much about the Arts Theatre and just everybody in general.”
