Before you book in Bexley
Noise
Fans and grilles are selected and attenuated to keep noise down.
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.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most Bexley businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
