Services
Contract Cleaning
Tailored daily cleaning services for commercial premises, including offices, schools, and hospitality venues. Our teams perform surface sanitisation, waste management, and equipment maintenance during agreed hours to minimise disruption. Clients benefit from consistent hygiene standards and flexible scheduling options.
Fogging Sanitisation
Pandemic-compliant decontamination using electrostatic fogging technology. This service eliminates viruses and bacteria from hard-to-reach areas in schools, offices, and healthcare facilities. The biocidal solution meets EN14476 standards for effectiveness against enveloped viruses including SARS-CoV-2.
Window Cleaning
Water-fed pole system for safe, streak-free window cleaning up to five storeys. This eco-friendly method uses purified water to clean external glass without ladders. Internal windows are cleaned using traditional squeegee techniques to maintain professional presentation standards.
Gutter Clearance
Professional gutter and downpipe maintenance to prevent water damage. Our technicians use triple-motor vacuums for high-level access, clearing debris and checking seals. Seasonal cleaning helps maintain property integrity and prevent costly structural issues from blocked drainage.
Carpet Cleaning
Hot water extraction cleaning for carpets and specialist treatments for upholstery. We remove stains, apply protective coatings, and reduce allergens using industry-leading equipment. Regular maintenance prolongs textile lifespan while maintaining hygienic environments in commercial spaces.
