How it works in St Helens
Check the void
We confirm void depth, grid size and any obstructions such as beams, sprinkler pipes or ductwork.
Set positions
Cassettes are placed against the lighting and grid layout so air reaches the whole space.
Hang and connect
Units are hung on drop rods, connected to pipework and the condensate line. We keep work areas in St Helens screened and tidy at the end of each day.
Test and commission
The condensate pump is water-tested, the system pressure tested and charged, and air directions set.
What to think about in St Helens
Ceiling grid
Compact cassettes drop into a 600 mm grid; full-size units need the grid adapting around a larger panel.
Working hours
Most St Helens businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Cleaning access
Filters need cleaning regularly, so cassettes should be reachable with a step ladder.
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 St Helens
