Things to check in Farnham
Frequency
Most units need a deep clean every one to two years; kitchens and salons more often.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
Downtime
Each unit is out of action for about an hour while it is cleaned.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
