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.
Filters
Filter grades should match the original design or current guidance for the building.
Conservation areas
Historic streets and listed buildings in and around Belfast are more likely to need planning permission for outdoor units on visible elevations. We check with the council's planning service before work is booked.
