Before you book in County Armagh
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
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.
Building Regulations
New or altered ventilation in Northern Ireland must meet Technical Booklet K. We design to it and hand over the commissioning records.
Working hours
Most County Armagh businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
