What to think about in Cardiff
Smells
Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Grease
Units near kitchens need cleaning more often, and sometimes relocating.
Working hours
Most Cardiff businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
