Local points to consider
Frequency
Most units need a deep clean every one to two years; kitchens and salons more often.
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.
Downtime
Each unit is out of action for about an hour while it is cleaned.
Leased premises
If your Darlington premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
