Local points to consider
Hygiene
Drip trays and coils must be kept clean to avoid biological growth.
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.
Energy
Fan upgrades and better controls can cut energy use significantly on older units.
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.
Types of premises we cover in Guildford
