Before you book in Watford
Space
Units need space in the ceiling void or a plant area with access for filter changes.
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.
Integration
Heat recovery pairs well with air conditioning, which handles the room heating and cooling.
Access and parking
Town-centre jobs in Watford often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Premises we work in around Watford
