Things to check in County Londonderry
Smells
Musty smells usually mean biological growth in the coil or tray; a deep clean and drain treatment normally cures them.
Conservation areas
Historic streets and listed buildings in and around County Londonderry 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.
Grease
Units near kitchens need cleaning more often, and sometimes relocating.
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.
